                                  THE COMPANY
 
     The Company is one of the leading manufacturers and marketers of brand name
nutritional supplements sold through domestic health food stores and is also
engaged in the sale of its products through national and regional drug store
chains, supermarkets, mass market retailers and Changes International, its
recently acquired network marketing company. The Company produces a full line of
nutritional supplements and offers the broadest product line in the industry
with more than 940 products and 1,700 stockkeeping units (SKU's). The Company's
product line includes vitamins, minerals, amino acids, fish and marine oils,
sports nutrition products and special formulas marketed under the TWINLAB(R)
trademark, a full line of herbal supplements and phytonutrients marketed under
the Nature's Herbs(R) and HealthCare Naturals(R) trademarks and herb teas
marketed under the Alvita(R) trademark. In addition, the Company markets a line
of nutritional supplements exclusively through Changes International. The
Company emphasizes the development and introduction of high-quality, unique
nutraceuticals and other products in response to emerging trends in the
nutritional supplement industry. The Company's broad product line, strong
history of new product introductions and innovations, superior marketing and
advertising programs and premium product quality have established TWINLAB,
Nature's Herbs and Alvita as leading and widely-recognized brands in the
nutritional supplement industry.
 
     Under the leadership of the Blechman family, Twinlab has achieved increased
net sales and income from operations every year since 1990. Since 1993, the
Company's net sales and income from operations have grown at compound annual
growth rates of 20.9% and 30.9%, respectively. For the year ended December 31,
1997, the Company generated net sales, net income and net income per share of
$213.2 million, $22.7 million and $0.84, respectively.
 
     The Company's products target consumers who utilize nutritional supplements
in their daily diet and who demand premium quality ingredients in a broad
variety of dosages and delivery methods. To reach the broadest possible consumer
market, the Company has developed a multi-branded and multi-channel distribution
strategy, consisting of the following categories:
 
   
     - Health Food Stores -- The Company's TWINLAB, Nature's Herbs and Alvita
       brand products are sold through a network of approximately 60
       distributors to nearly 11,000 health food stores and other selected
       retail outlets. The health food store channel of distribution has
       continued to experience significant growth in recent years as national
       chains, including those which sell the Company's products, such as
       General Nutrition Companies, Inc. ("GNC"), Whole Foods Market, Inc.
       ("WFM"), Wild Oats Markets, Inc. ("Wild Oats") and other industry
       participants continue to add stores in new and existing markets. The
       Company believes that it has a competitive advantage in the health food
       store channel due to the high quality of its products which is a direct
       result of its use of premium ingredients, its modern manufacturing
       facilities and its comprehensive quality control procedures. Sales to the
       health food store channel, primarily through distributors, continue to
       represent the Company's largest market, totaling approximately $171.6
       million, or approximately 80.5%, of the Company's net sales in 1997. The
       Company believes that its products have a presence in over 90% of the
       health food stores in the United States, but that only approximately 12%
       of such stores carry a comprehensive line of the Company's products.
       Management believes that the continued expansion of health food store
       retail outlets and the strong growth characteristics of the nutritional
       supplement industry, combined with health food retailers' success with
       the Company's product lines, provide Twinlab with significant
       opportunities to increase sales in the health food store channel.

     - Mass Market Retailers -- The Company continues to increase its
       penetration of the fast growing mass market retail channel, which
       consists of drug store chains, supermarkets and other mass merchandisers.
       The Company is currently a provider of private label herbal products to
       Wal-Mart Stores, Inc. ("Wal-Mart"), which are being sold under Wal-Mart's
       proprietary Spring Valley brand name. The Company also sells its products
       through national and regional drug store and supermarket chains, such as
       Rite Aid Corporation, Duane Reade Inc., American Stores, Inc. and
       Albertson's, Inc., under its established TWINLAB, HealthCare Naturals and
       Alvita brand names. The Company believes that the mass market
       distribution channel affords significant growth opportunities and intends
       to continue to introduce new products and new brands designed
       specifically for customers in this channel. During 1998, the Company
       plans to introduce a line of sports nutrition products under a new
       proprietary brand name which will be sold exclusively in the mass market
       channel. Approximately $14.0 million or 6.6% of the Company's 1997 net
       sales were attributable to mass market retailers compared to $3.4 million
       or 2.0% in 1996. Due to a variety of recent programs initiated by the
       Company, Twinlab expects to experience significant growth in this
       category during fiscal 1998. See "Recent Trends and Developments -- First
       Quarter Trends."
    
 
     - Network Marketing -- Through Changes International, a network marketing
       company which the Company acquired in November 1997, Twinlab develops,
       markets and sells vitamins, herbs and nutritional supplements exclusively
       under the Changes(R) brand name. Changes International operates through a
       large sales force of independent distributors located throughout the
       United States and Canada who sell directly to consumers. Changes
       International's products include Changes Relief, an advanced supplement
       that nutritionally supports healthy bone and joint functions, and
       Perfor-Max, an antioxidant formula containing grapeseed extract, pine
       bark extract and tumeric. All of Changes International's products are
       specially formulated and packaged exclusively for the network marketing
       channel and are not intended for sale to retail outlets. The Company is
       making a significant investment to enhance Changes International's
       management team, infrastructure and management information systems in an
       effort to expand its distributor and customer base and to increase sales
       in this distribution channel. During 1998, the Company intends to more
       than double the size of Changes International's nutritional supplement
       line, beginning with the introduction of eight new products during the
       first half of 1998. Changes International was founded in 1994 and
       generated gross sales of $41.5 million in 1997 ($7.0 million in fiscal
       1997 after its acquisition by the Company).
 
     The Company believes it is well positioned to capitalize on the continued
growth of the vitamin, herb and nutritional supplements market and the multiple
distribution channels through which these products are sold. Based on estimates
in 1997 market reports conducted by Packaged Facts (the "Packaged Facts
Report"), an independent research firm, the retail market for vitamins, minerals
and other supplements (excluding sports nutrition and diet products; the "VMS
Products") has grown at a compound annual rate of 15% from $3.7 billion in 1992
to $6.5 billion in 1996. Leading this increase, the retail market for
supplements (primarily herbal products) has grown at a compound annual rate of
41.7% from $570 million in 1992 to $2.3 billion in 1996. In addition, according
to Packaged Facts, the retail market for sports nutrition products has grown at
a compound annual rate of 10.7% from $585 million in 1992 to $880 million in
1996. Packaged Facts forecasts 13.6% compound annual growth in the market for
VMS Products, including 25% compound annual growth in the market for
supplements, through the year 2001. Management believes this continued growth
will be fueled by (i) favorable demographic trends towards older Americans, who
are more likely to consume nutritional supplements; (ii) product introductions
in response to new scientific research findings supporting the positive health
effects of certain nutrients; (iii) the nationwide trend toward preventive
medicine in response to rising health care costs; (iv) increased consumer
interest in herbs and herb-related supplements; and (v) the heightened
understanding and awareness of healthier lifestyles and the connection between
diet and health. Moreover, although the industry has grown dramatically in
recent years, there is still a large untapped domestic market as only an
estimated 50% of Americans currently consume vitamins, herbs and nutritional
supplements on a regular basis.

     Vitamins and nutritional supplements are sold through several channels of
distribution: health food stores, mass market retailers (drug store chains,
supermarkets and other mass merchandisers), and direct sales channels (including
network marketing and catalog distribution). In 1996, according to Packaged
Facts, the mass market channel accounted for approximately 45.8% of sales of VMS
Products, health food stores accounted for 38.2% of sales and the remaining
16.0% of sales were generated through direct selling, mail order and the
internet.
 
                               BUSINESS STRATEGY
 
     The Company's strategy is to continue to increase sales and profits by
furthering its leadership position in the sale of vitamins, herbs and
nutritional supplements to the health food store channel while continuing to
increase sales and market share in the mass market and network marketing
channels. The Company also intends to seek opportunities to enter other channels
of distribution, including catalog distribution. Twinlab plans to implement this
strategy both by capitalizing on the strength of its established brands as well
as through the development and introduction of new brands. In addition, the
Company expects to continue to develop and introduce new products and product
innovations for each of its distribution channels, to increase its penetration
of foreign markets and to provide the advertising, marketing, operational and
personnel support necessary to grow its businesses. Twinlab intends to achieve
these goals while continuing its past emphasis on its financial performance and
the overall efficiency of its operations. Specifically, the Company seeks to:
 
     Further Develop Portfolio of Brands -- Twinlab has developed a portfolio of
core brands which are among the most recognized in the vitamin and nutritional
supplement industry. The Company intends to continue to nurture and extend the
reach of its TWINLAB, Nature's Herbs and Alvita brands in the health food
distribution channel while furthering the development of its portfolio of
private label and proprietary brands, including the HealthCare Naturals and
Changes brands, targeted to the mass market retail and network marketing
channels. During 1998, the Company plans to introduce a line of sports nutrition
products under a new proprietary brand name which will be sold exclusively in
the mass market channel. As in the past, the Company will continue to promote
its brands through strong marketing and advertising programs. Management
believes that Twinlab has one of the largest marketing and advertising budgets
as a percentage of sales in the nutraceutical industry and that the strong brand
name recognition of its products is, in part, a direct result of this support.
In fiscal 1997, the Company spent $15.9 million, an increase of 25.1% over
fiscal 1996, on marketing and advertising to promote its products. The Company
has budgeted $20.5 million for marketing and advertising expenses in fiscal
1998, a 29.2% increase over fiscal 1997.
 
     Further Develop Multiple Channels of Distribution -- The Company intends to
continue to increase its penetration of the health food store channel, expand
its mass market retail and network marketing businesses, and enter additional
distribution channels, such as catalog distribution, through internal growth and
selective acquisitions. See "Recent Trends and Developments -- Bronson
Acquisition." By utilizing a multiple distribution channel approach, the Company
believes it will be well positioned to also reach customers who historically
have not shopped in health food stores.
 
   
     Continue to Introduce New Products and Product Innovations -- A cornerstone
of the Company's success has been its ability to rapidly utilize recent
scientific and medical findings in its new product development efforts. The
Company has consistently been among the first in its industry to introduce new
products and product innovations which anticipate and meet customer demands for
newly identified nutritional supplement benefits. As part of its ongoing
research and development effort, the Company maintains an extensive database and
actively researches and monitors a wide variety of publications containing
scientific and medical research. The Company's geographically diverse network of
distributors allows Twinlab to achieve immediate and broad distribution for new
product launches. From 1991 through 1997, the Company introduced over 560
products, with over 100 new products introduced in 1997 alone. Net sales during
1997 from new products introduced in 1997 were approximately $17.7 million, or
approximately 8.3% of net sales. In 1998, the Company expects to introduce over
100 new products in the health food store and mass market retail channels, 18 of
which have already been introduced, and plans to more than double the number of
products offered by Changes International.

     Increase Penetration of Foreign Markets -- Management believes that there
are substantial opportunities for the Company to expand its presence in foreign
markets. As part of its continuing efforts to increase international sales, the
Company recently hired a Director of International Sales. The Company's
international sales force is supported by a network of 37 overseas distributor
organizations, serving 56 foreign countries. Approximately 5.1%, or $10.9
million, of the Company's net sales in 1997 were derived from international
sales originating from overseas distributor organizations. The Company presently
has distribution agreements covering fourteen western European countries,
including Great Britain, France, Belgium, the Netherlands and the Scandinavian
countries; six eastern European countries, including Russia; nine Latin American
countries, including Mexico, Brazil and Argentina; eight Middle Eastern
countries, including Israel and Saudi Arabia; and several other countries in the
Far East and the Caribbean. The Company has also initiated new programs to
qualify distributors in Italy and China.
    
 
     Supplement Internal Growth Through Strategic Acquisitions -- The Company
actively pursues acquisition opportunities that complement or extend its
existing product line, expand its distribution channels or are compatible with
its business philosophy and strategic goals. The Company believes that its
leading and widely recognized brand names, broad distribution capabilities and
proven ability to generate sales of its products through successful marketing
programs provide it with a strategic advantage in identifying potential
acquisition candidates. In addition, the Company's success with past
acquisitions provides it with the knowledge to successfully integrate future
acquisitions into its operations. See "Recent Trends and Developments -- Bronson
Acquisition."
 
     Ongoing Investment in Personnel and Infrastructure -- The Company continues
to make significant investments in developing its management team and building
its infrastructure to support the growth of its businesses. The Company recently
hired several key individuals, including a new Chief Financial Officer, a
President of Mass Market Sales and a Director of International Sales, to enhance
its senior management team. As part of its ongoing efforts to maintain its
reputation for providing the highest quality products and services to its
customers, the Company continues to invest in its manufacturing and distribution
facilities and management information systems. The Company recently broke ground
on an approximately $13.0 million expansion of its state-of-the-art
manufacturing, distribution and warehouse facility in American Fork, Utah (the
"Utah Facility"). The total size of the Utah Facility will increase from 57,000
square feet to approximately 143,000 square feet and will substantially increase
the Company's production capacity.
 
     Twinlab was incorporated under the laws of the State of Delaware in 1996
and maintains its principal executive offices at 2120 Smithtown Avenue,
Ronkonkoma, New York 11779. Its telephone number is 516-467-3140.
 
                         RECENT TRENDS AND DEVELOPMENTS
 
     Bronson Acquisition -- On March 17, 1998, the Company entered into a
definitive agreement to acquire substantially all of the assets and assume
certain liabilities of the Bronson division ("Bronson") of Jones Medical
Industries, Inc. ("Jones") (the "Bronson Acquisition"). The Company expects that
the closing of the Bronson Acquisition will occur during the second quarter of
fiscal 1998. Bronson's net sales and operating income for the fiscal year ended
December 31, 1997, were approximately $32.1 million, and $9.5 million,
respectively. The purchase price is $55.0 million in cash, subject to certain
adjustments, which the Company intends to finance with a portion of the net
proceeds of the Offerings. In the event the Offerings are not consummated, the
Company would seek to amend its Revolving Credit Facility (as hereinafter
defined) to increase the permitted borrowings and to finance the Bronson
Acquisition with borrowings thereunder.
 
     Bronson manufactures, markets and distributes a line of over 350 vitamins,
herbs, nutritional supplements and health and beauty aids, which are sold under
the Bronson(R) name through catalogs and direct mailings to customers, including
healthcare and nutritional professionals and mail order and retail customers.
Bronson also markets its MD Pharmaceutical(R) brand exclusively to United States
military commissaries. Bronson's products are manufactured in a 30,000 square
foot facility in Tempe, Arizona, which the Company will acquire and operate
after the closing. This facility also manufactures private label nutritional
supplements for other companies on a contract manufacturing basis. Pursuant to a
Transition Services Agreement, Jones will
                                        8
<PAGE>   10
 
continue to provide sales services and packaging and distribution operations for
Bronson's products through December 31, 1998.
 
     The Bronson Acquisition is subject to certain customary conditions, and
there can be no assurance that the Bronson Acquisition will be consummated. The
Offerings are not contingent upon the consummation of the Bronson Acquisition.
 
     First Quarter Trends -- In the first quarter of 1998, the Company received
a substantial increase in orders for its herbal supplement products, including a
significant increase in orders from Wal-Mart for herbal products which are being
sold under Wal-Mart's proprietary Spring Valley brand name. This increase is due
to increased demand at the retail level and to the fact that the number of SKU's
sold under this brand name at Wal-Mart more than doubled during the first
quarter of 1998. The Company has made several adjustments to its operations to
accommodate this increased demand for its herbal products, including the use of
production capacity at the New York Facility (as hereinafter defined) to produce
herbal supplement products and the installation of additional manufacturing
equipment at both the New York and Utah Facilities. As a result of these
operational adjustments and the Company's decision to reduce promotions offered
to distributors during the first quarter of 1998, the Company's mix of product
sales during the first quarter of 1998 will differ substantially from the
product mix in the comparable period in 1997. For the first quarter of 1998,
herbal supplements will represent a substantially greater portion of the
Company's total net sales, and sales of vitamins, minerals and nutritional
supplements products will represent a smaller percentage of total net sales and
decline significantly from the comparable period in 1997. Nevertheless, the
Company anticipates that its overall growth rate in net sales in the first
quarter of 1998 will be comparable to that achieved in the first quarter of
1997, as the increased sales of herbal products will more than offset the
decreased sales of vitamins, minerals and nutritional supplements (all of the
foregoing first quarter comparisons exclude the impact of Changes
International). The Company believes that there has been no material decline in
retail sales of its vitamin, mineral and nutritional supplement products during
the first quarter of 1998, as there has been adequate inventory of its products
in the distribution channel. The Company plans to adjust its production mix
during the second quarter of 1998 to increase the production of vitamins,
minerals and nutritional supplements compared to the first quarter of 1998, as
additional capacity comes on line and production schedules are adjusted, and
expects to realize increased sales of these products during the second quarter
of 1998 as compared to the first quarter of 1998.

(a) Reflects $15.3 million of nonrecurring non-competition agreement expense and
    $0.4 million of Transaction expenses.
 
(b) Basic and diluted income per share has been computed by dividing net income
    (and pro forma income before extraordinary item and pro forma net income for
    1995 and 1996), after reduction for Preferred Stock (as hereinafter defined)
    dividends, by the applicable weighted average shares outstanding.
 
   
(c) Supplemental basic and diluted net income per share for the year ended
    December 31, 1997, after giving effect to the Redemption (as hereinafter
    defined), would be $0.89. Such calculation assumes the Redemption occurred
    on January 1, 1997, and includes the assumed issuance of 1,033,000 shares of
    Common Stock required to effect the Redemption and the elimination of
    interest expense and amortization of deferred finance costs, net of tax,
    relating to the redeemed Notes.
    
 
(d) Diluted weighted average shares outstanding for 1993 through 1996 represents
    the number of equivalent shares outstanding after giving retroactive effect
    to Twinlab's 18.5 for 1 stock split (effected in the form of a stock
    dividend) and assumes that the 10,175,000 shares of Common Stock issued in
    connection with the Acquisition (as hereinafter defined) and the 8,500,000
    shares of Common Stock issued in connection with the Company's IPO were
    outstanding. See Notes to the Consolidated Financial Statements of the
    Company included elsewhere in this Prospectus.
 
(e) Prior to May 1996, the Company consisted of "S" corporations and,
    accordingly, federal and state taxes were generally paid at the shareholder
    level only. Upon consummation of the Transactions, the Company eliminated
    its "S" corporation status and, accordingly, became subject to federal and
    state income taxes.
 
(f) Represents the write-off of previously deferred finance costs incurred in
    connection with the Original Credit Facility (as hereinafter defined) (the
    "Extraordinary Item").
 
(g) The unaudited pro forma results of operations assume the Transactions and
    the subsequent IPO occurred on January 1, 1995, and exclude the effect of
    (i) the nonrecurring non-competition agreement expense, (ii) the Transaction
    expenses, (iii) the Extraordinary Item and (iv) the dividends paid on the
    Preferred Stock which was redeemed in connection with the IPO, and reflects
    the additional interest expense relating to the financing of the Acquisition
    and the change in tax status described in Note (e) above. This data has been
    prepared for comparative purposes only and does not purport to represent
    what the Company's actual results of operations would have been had the
    Transactions and the subsequent IPO in fact occurred on January 1, 1995.
 
(h) Income from operations margin equals income from operations as a percentage
    of net sales.
 
   
(i) Gives effect to the consummation of the Offerings (using an assumed offering
    price of $38.875 per share) and the application of the estimated net
    proceeds therefrom as if they occurred on December 31, 1997. The application
    of the net proceeds assumes the consummation of the Bronson Acquisition and
    the repayment of approximately $13.9 million of outstanding borrowings under
    the Revolving Credit Facility (including accrued and unpaid interest
    thereon), which borrowings are expected to have been reduced through
    repayments to $5.6 million (including accrued and unpaid interest thereon),
    prior to the consummation of the Offerings.

                                  RISK FACTORS
 
     Prospective purchasers of the Common Stock should carefully consider the
following risk factors, as well as the other information contained, and
incorporated by reference, in this Prospectus before making an investment in the
Common Stock.
 
     This Prospectus contains or incorporates by reference certain
"forward-looking statements" within the meaning of Section 27A of the Securities
Act of 1933, as amended (the "Securities Act"), which represent the Company's
expectations or beliefs, including, but not limited to, statements concerning
industry performance, the Company's operations, performance, financial
condition, growth and acquisition strategies, margins and growth in sales of the
Company's products. For this purpose, any statements contained or incorporated
by reference in this Prospectus that are not statements of historical fact may
be deemed to be forward-looking statements. Such statements can be identified by
the use of forward-looking terminology such as "believes," "expects," "may,"
"will," "should" or "anticipates" or the negative thereof or other variations
thereon or comparable terminology, or by discussions of strategy. See, e.g.,
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," "Prospectus Summary -- Business Strategy," and
"Business -- Business Strategy." No assurance can be given that the future
results covered by the forward-looking statements will be achieved. These
statements by their nature involve substantial risks and uncertainties, certain
of which are beyond the Company's control. The following matters constitute
cautionary statements identifying important factors with respect to such
forward-looking statements, including certain risks and uncertainties, that
could cause actual results to vary materially from the future results covered in
such forward-looking statements. Other factors could also cause actual results
to vary materially from the future results covered in such forward-looking
statements.
 
UNCERTAINTY RELATED TO ACQUISITIONS; BROAD DISCRETION IN USE OF PROCEEDS
 
     The Company intends to actively pursue acquisition opportunities that
complement or extend its existing products, expand its distribution channels or
are compatible with its business philosophy and strategic goals. Acquisitions
involve a number of risks that could adversely affect the Company's operating
results, including the diversion of management's attention, the assimilation of
operations and personnel of the acquired companies, the amortization of acquired
intangible assets and the potential loss of key employees of the acquired
companies. There can be no assurance that the Company will consummate future
acquisitions on satisfactory terms, if at all, that adequate financing will be
available on terms acceptable to the Company, if at all, or be permitted under
the Company's financing instruments, that any acquired product lines or
businesses will be successfully integrated or that such product lines or
businesses will ultimately have a positive impact on the Company, its financial
condition or results of operations. In addition, such acquisitions could result
in substantial equity dilution to existing stockholders. See
"Business -- Business Strategy."
 
     The Company intends to finance the purchase price of the Bronson
Acquisition with $56.5 million (including related fees and expenses) of the net
proceeds of the Offerings. There can be no assurance that the Bronson
Acquisition will be consummated. In the event the Bronson Acquisition is not
consummated, the Company intends to use the resulting excess net proceeds from
the Offerings for working capital and other general corporate purposes,
including to pursue acquisition opportunities. Accordingly, the Company may have
broad discretion in using the net proceeds of the Offerings. An investor will
not have the opportunity to evaluate the economic, financial and other relevant
information which will be utilized by the Company in determining the application
of such proceeds. See "Use of Proceeds."
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company believes that its continued success depends to a significant
extent on the management and other skills of Brian Blechman, Dean Blechman, Neil
Blechman, Ross Blechman and Steve Blechman (the "Blechman Brothers"), as well as
its ability to retain other key employees and to attract skilled personnel in
the future to manage the growth of the Company. The loss or unavailability of
the services of one or more of the Blechman Brothers could have a material
adverse effect on the Company. The Company has employment
 
                                       13
<PAGE>   15
 
agreements with each of the Blechman Brothers and upon completion of the
Offerings each of the Blechman Brothers will own approximately 5.3% of the
outstanding Common Stock. See "Management."
 
CERTAIN GOVERNMENT ACTION AND ADVERSE PUBLICITY REGARDING CERTAIN PRODUCTS
CONTAINING EPHEDRINE
 
   
     Approximately 15 of the Company's products include an herb known as "Ma
Huang," which contains naturally-occurring ephedrine. Certain of such products
also contain caffeine or other central nervous system stimulants. Such products
accounted for approximately 13.0% of the Company's net sales in 1997. The
Company's products which contain Ma Huang are generally marketed for
bodybuilding, weight loss, sports nutrition and other purposes, including
increased endurance and energy, generally in conjunction with diet or exercise,
and as natural alternatives to over-the-counter medications.
    
 
   
     Ma Huang has been the subject of certain adverse publicity in the United
States and other countries relating to alleged harmful or adverse effects. The
United States Food and Drug Administration (the "FDA") has proposed regulations
relating to the sale of dietary supplements containing Ma Huang which, if
promulgated in final form, would require the Company to substantially
reformulate and relabel almost all of its Ma Huang products, limit potency,
require warnings, prohibit certain combination products and preclude the Company
from making bodybuilding and weight loss claims for such products. Comments from
industry participants and inquiries from Committees of the United States
Congress have been filed with the FDA challenging the scientific and legal basis
for the proposed regulations. The Company is not able to predict whether the
FDA's proposed regulations will become final. There can be no assurance as to
the effect that any resulting reformulation, relabeling or change in the
marketing of the Company's products would have on the sales of such products. In
1996, the Company introduced a line of Ma Huang-free products as alternatives to
certain of its bodybuilding and sports nutrition products which currently
contain Ma Huang. The Company's net sales of Ma Huang-free products were $1.9
million for fiscal 1997. There can be no assurance that sales of such
alternative products would offset any decrease in sales attributable to any
reformulation or relabeling of the Company's Ma Huang products.
    
 
     A number of state and local governments have proposed or passed legislation
prohibiting or regulating the sale of Ma Huang products. The Company's products
containing Ma Huang may become subject to further federal, state, local or
foreign laws or regulations, which could also require the Company to reformulate
its products with reduced ephedrine levels or with a substitute for Ma Huang
and/or relabel its products with different warnings or revised directions for
use. There can be no assurance that the loss of sales of the Company's Ma Huang
products would not have a material adverse effect on the Company. See
"Business -- Legal Matters."
 
LEGAL MATTERS
 
     The Company, like other retailers, distributors and manufacturers of
products that are ingested, faces an inherent risk of exposure to product
liability claims in the event that the use of its products results in injury.
The Company may be subjected to various product liability claims, including,
among others, that its products contain contaminants or include inadequate
instructions as to use or inadequate warnings concerning side effects and
interactions with other substances. While such claims to date have not been
material to the Company and the Company maintains product liability insurance,
there can be no assurance that product liability claims and the resulting
adverse publicity will not have a material adverse effect on the Company. See
"Business -- Legal Matters." The Company carries insurance in the types and
amounts that management considers reasonably adequate to cover the risks
associated with its business. There can be no assurance that such insurance will
continue to be available at a reasonable cost, or if available will be adequate
to cover liabilities.
 
     The State of California and the National Resources Defense Council (the
"NRDC") filed lawsuits against the Company and a large number of manufacturers
of dietary supplements containing calcium, claiming that naturally-occurring
lead levels in these supplements exceed acceptable levels under California law
("Proposition 65"). The NRDC settled its suit with the manufacturers, including
the Company. The State of California settled the first of two phases of its
lawsuit with the Company and the other manufacturers
 
                                       14
<PAGE>   16
 
and is engaged in settlement discussions with respect to the remainder of the
case. The Company also received notice of a possible State of California legal
claim relating to alleged toxic impurities in fish oil products. No action has
been filed. There can be no assurance that the Company will not be the subject
of future Proposition 65 claims asserted by the State of California or private
parties or that any such claim or the existing California lawsuit, if
successful, might not have a material adverse effect on the Company's
operations.
 
     The Company is presently engaged in various other legal actions, and,
although ultimate liability cannot be determined at the present time, the
Company believes that the amount of any such liability, if any, from these other
actions, after taking into consideration the Company's insurance coverage, will
not have a material adverse effect on its results of operations and financial
condition. See "Business -- Legal Matters."
 
GOVERNMENT REGULATION
 
     The manufacturing, processing, formulating, packaging, labeling and
advertising of the Company's products are subject to regulation by one or more
federal agencies, including the FDA, the Federal Trade Commission (the "FTC"),
the United States Department of Agriculture and the Environmental Protection
Agency. These activities are also regulated by various agencies of the states,
localities and foreign countries to which the Company's products are distributed
and in which the Company's products are sold. The FDA, in particular, regulates
the formulation, manufacture and labeling of vitamin and other nutritional
supplements.
 
     On October 25, 1994, the President signed into law the Dietary Supplement
Health and Education Act of 1994 ("DSHEA"). This new law revises the provisions
of the Federal Food, Drug, and Cosmetic Act (the "FFDC Act") concerning the
composition and labeling of dietary supplements and, in the judgment of the
Company, is favorable to the dietary supplement industry. The legislation
creates a new statutory class of "dietary supplements." This new class includes
vitamins, minerals, herbs, amino acids and other dietary substances for human
use to supplement the diet, and the legislation grandfathers, with certain
limitations, dietary ingredients on the market before October 15, 1994. A
dietary supplement which contains a new dietary ingredient, one not on the
market before October 15, 1994, will require evidence of a history of use or
other evidence of safety establishing that it will reasonably be expected to be
safe. The substantial majority of the products marketed by the Company are
classified as dietary supplements under the FFDC Act.
 
     Both foods and dietary supplements are subject to the Nutrition Labeling
and Education Act of 1990 (the "NLEA"), which prohibits the use of any health
claim for foods, including dietary supplements, unless the health claim is
supported by significant scientific agreement and is either pre-approved by the
FDA or the subject of substantial government scientific publications and a
notification to the FDA. To date, the FDA has approved the use of only limited
health claims for dietary supplements. However, among other things, the DSHEA
amends, for dietary supplements, the NLEA by providing that "statements of
nutritional support" may be used in labeling for dietary supplements without FDA
preapproval if certain requirements, including prominent disclosure on the label
of the lack of FDA review of the relevant statement, possession by the marketer
of substantiating evidence for the statement and post-use notification to the
FDA, are met. Such statements may describe how particular nutritional
supplements affect the structure, function or general well-being of the body
(e.g. "promotes your cardiovascular health").
 
     The FDA issued final dietary supplement labeling regulations in 1997 that
require the Company to revise most of its product labels by 1999. The
regulations also currently require the Company to submit notification to the FDA
of all "statements of nutritional support," a process that the Company has not
fully completed.
 
     Advertising and label claims for dietary supplements and conventional foods
have been regulated by state and federal authorities under a number of disparate
regulatory schemes. There can be no assurance that a state will not interpret
claims presumptively valid under federal law as illegal under that state's
regulations, or that future FDA regulations or FTC decisions will not restrict
the permissible scope of such claims.
 
     Governmental regulations in foreign countries where the Company plans to
commence or expand sales may prevent or delay entry into the market or prevent
or delay the introduction, or require the reformulation, of certain of the
Company's products. Compliance with such foreign governmental regulations is
generally the
 
                                       15
<PAGE>   17
 
responsibility of the Company's distributors for those countries. These
distributors are independent contractors over whom the Company has limited
control.
 
     As a result of the Company's efforts to comply with applicable statutes and
regulations, the Company has from time to time reformulated, eliminated or
relabeled certain of its products and revised certain provisions of its sales
and marketing program. The Company cannot predict the nature of any future laws,
regulations, interpretations or applications, nor can it determine what effect
additional governmental regulations or administrative orders, when and if
promulgated, would have on its business in the future. They could, however,
require the reformulation of certain products to meet new standards, the recall
or discontinuance of certain products not capable of reformulation, additional
recordkeeping, expanded documentation of the properties of certain products,
expanded or different labeling, and/or scientific substantiation. Any or all of
such requirements could have a material adverse effect on the Company's results
of operations and financial condition.
 
     Compliance with the provisions of national, state and local environmental
laws and regulations has not had a material adverse effect upon the capital
expenditures, earnings, financial position, liquidity or competitive position of
the Company. See also "Business -- Legal Matters" and "-- Regulatory Matters."
 
RESTRICTIONS IMPOSED BY TERMS OF THE COMPANY'S INDEBTEDNESS
 
     The Indenture (as hereinafter defined) and the Revolving Credit Facility
impose upon the Company certain financial and operating covenants, including,
among others, requirements that the Company maintain certain financial ratios
and satisfy certain financial tests, limitations on capital expenditures and
restrictions on the ability of the Company to incur debt, pay dividends or take
certain other corporate actions, all of which may restrict the Company's ability
to expand or to pursue its business strategies. Changes in economic or business
conditions, results of operations or other factors could in the future cause a
violation of one or more covenants in the Company's debt instruments. See
"Description of Certain Indebtedness."
 
COMPETITION
 
     The business of developing, manufacturing and selling vitamins, herbs,
sports nutrition products, nutritional supplements and other nutraceuticals is
highly competitive. There are numerous companies in the vitamin and nutritional
supplement industry selling products to retailers such as mass merchandisers,
drug store chains, independent drug stores, supermarkets and health food stores.
Certain of the Company's competitors are substantially larger and have greater
financial resources than the Company. See "Business -- Competition."
 
ABSENCE OF CLINICAL STUDIES AND SCIENTIFIC REVIEW; EFFECT OF PUBLICITY
 
     While the Company conducts extensive quality control testing on its
products, the Company generally does not conduct or sponsor clinical studies on
its products. See "Business -- Manufacturing and Product Quality." The Company's
products consist of vitamins, minerals, herbs and other ingredients that the
Company regards as safe when taken as suggested by the Company. However, because
the Company is highly dependent upon consumers' perception of the safety and
quality of its products as well as similar products distributed by other
companies (which may not adhere to the same quality standards as the Company),
the Company could be adversely affected in the event any of the Company's
products, or any similar products distributed by other companies, should prove
or be asserted to be harmful to consumers. In addition, because of the Company's
dependence upon consumer perceptions, adverse publicity associated with illness
or other adverse effects resulting from consumers' failure to consume the
Company's products as suggested by the Company or other misuse or abuse of the
Company's products or any similar products distributed by other companies could
have a material adverse effect on the Company's results of operations and
financial condition.
 
     Furthermore, the Company believes the recent growth experienced by the
nutritional supplement market is based in part on national media attention
regarding recent scientific research suggesting potential health benefits from
regular consumption of certain vitamins and other nutritional products. Such
research has been described in major medical journals, magazines, newspapers and
television programs. The scientific research
                                       16
<PAGE>   18
 
to date is preliminary, and there can be no assurance of future favorable
scientific results and media attention or of the absence of unfavorable or
inconsistent findings.
 
DEPENDENCE ON DISTRIBUTORS
 
     The Company's success depends in part upon its ability to attract, retain
and motivate a large base of distributors, and its ability to maintain a
satisfactory relationship with Tree of Life Inc. ("Tree of Life") and GNC. Tree
of Life and GNC accounted for approximately 19% and 23%, respectively, of the
Company's net sales in 1997. The loss of Tree of Life or GNC as a distributor,
or the loss of a significant number of other distributors, or a significant
reduction in purchase volume by Tree of Life, GNC or such other distributors,
for any reason, would have a material adverse effect on the Company's results of
operations and financial condition. See "Business -- Sales and Distribution."
 
AVAILABILITY OF RAW MATERIALS
 
     Substantially all of the Company's herbal supplements and herb teas contain
ingredients that are harvested by and obtained from third-party suppliers, and
many of those ingredients are harvested internationally and only once per year
or on a seasonal basis. An unexpected interruption of supply, such as a harvest
failure, could cause the Company's results of operations derived from such
products to be adversely affected. Although the Company has generally been able
to raise its prices in response to significant increases in the cost of such
ingredients, the Company has not always in the past been, and may not in the
future always be, able to raise prices quickly enough to offset the effects of
such increased raw material costs.
 
INTELLECTUAL PROPERTY PROTECTION
 
     The Company's trademarks are valuable assets which are very important to
the marketing of its products. The Company's policy is to pursue registrations
for all of the trademarks associated with its key products. The Company has
approximately 289 trademark registrations with the United States Patent and
Trademark Office. The Company relies on common law trademark rights to protect
its unregistered trademarks. Common law trademark rights do not provide the
Company with the same level of protection as would U.S. federal registered
trademarks. In addition, common law trademark rights extend only to the
geographic area in which the trademark is actually used, while U.S. federal
registration prohibits the use of the trademark by any third party anywhere in
the United States.
 
CONTROL BY PRINCIPAL STOCKHOLDERS; SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of the Offerings, Green Equity Investors II, L.P., an
affiliate of Leonard Green & Partners, L.P. ("GEI") will own 16.8% and the
Blechman Brothers will own 26.5%, of the Common Stock of Twinlab. As a result,
GEI and the Blechman Brothers will have significant influence over all matters
requiring approval by the Company's stockholders without the approval of
minority stockholders. Such influence could adversely affect the market price of
the Common Stock or delay or prevent a change in control of the Company. See
"Principal and Selling Stockholders."
 
     The Blechman Brothers and Stephen L. Welling (collectively, the "Senior
Executive Officers") and GEI are eligible to sell their shares of Common Stock
pursuant to Rule 144 ("Rule 144") under the Securities Act at prescribed times
and subject to the manner of sale, volume, notice and information restrictions
of Rule 144. The Company has granted the Senior Executive Officers and the
Selling Stockholders certain demand and piggyback registration rights covering
an aggregate of 18,176,250 shares of Common Stock (14,176,250 shares after the
consummation of the Offerings). The Senior Executive Officers and the Selling
Stockholders, who collectively are the beneficial owners of an aggregate of
18,180,420 shares of Common Stock (14,180,420 shares after the consummation of
the Offerings), and the Company have agreed with the Underwriters, subject to
certain exceptions, not to directly or indirectly, offer, sell, contract to
sell, grant any option to purchase or otherwise dispose of, without the prior
written consent of Bear, Stearns & Co. Inc. ("Bear Stearns"), any Common Stock,
or any securities convertible into or exchangeable or exercisable for, or
warrants, options or rights to purchase or acquire Common Stock or in any other
manner transfer all or a
 
                                       17
<PAGE>   19
 
portion of the economic consequences associated with the ownership of any Common
Stock, or enter into any agreement to do any of the foregoing, for a period of
90 days after the date of this Prospectus. Upon the expiration of such 90 day
period, such holders will in general be entitled to dispose of their shares of
Common Stock, although the shares of Common Stock held by affiliates of the
Company will continue to be subject to the restrictions of Rule 144 under the
Securities Act. Sales of substantial amounts of such shares in the public market
or the perception that such sales could occur could adversely affect the market
price of the shares of Common Stock and the Company's ability to raise
additional capital at a price favorable to the Company. See "Shares Eligible for
Future Sale" and "Underwriting."
 
ANTI-TAKEOVER PROVISIONS
 
     The Company's Second Amended and Restated Certificate of Incorporation (the
"Certificate of Incorporation") and its Amended and Restated By-laws (the
"By-laws"), as well as Delaware corporate law, contain certain provisions that
could have the effect of making it more difficult for a third party to acquire,
or discouraging a third party from attempting to acquire, control of the
Company. Certain of these provisions impose various procedural and other
requirements, including advance notice and other provisions, that could make it
more difficult for stockholders to effect certain corporate actions. The
Company's Board of Directors has the authority to issue additional shares of
preferred stock and to determine the designations, preferences and rights and
the qualifications or restrictions of those shares without any further vote or
action by the stockholders. The rights of the holders of Common Stock will be
subject to, and may be adversely affected by, the rights of the holders of any
preferred stock that may be issued in the future. The issuance of preferred
stock, while providing desirable flexibility in connection with possible
acquisitions and other corporate actions, could have the effect of making it
more difficult for a third party to acquire a majority of the outstanding voting
stock of the Company. These provisions could limit the price that certain
investors might be willing to pay in the future for shares of Common Stock.
Furthermore, certain provisions of the Indenture and the Company's Amended and
Restated Revolving Credit Facility (the "Revolving Credit Facility") provide for
the acceleration of the indebtedness evidenced thereby upon the occurrence of
certain change in control events (as defined in such debt instruments), which
provisions could also tend to prevent or discourage the acquisition of the
Company by a third party. See "Description of Capital Stock" and "Description of
Certain Indebtedness."
 
HOLDING COMPANY STRUCTURE; RESTRICTIONS ON DIVIDENDS
 
     Twinlab conducts its business through its direct and indirect subsidiaries
and has no operations of its own. The principal assets of Twinlab are the
capital stock of its direct and indirect subsidiaries, Twin, ARP and Changes
International. Accordingly, Twinlab has no independent means of generating
revenues. As a holding company, Twinlab's internal sources of funds to meet its
cash needs, including payment of expenses, are dividends and other permitted
payments from its direct and indirect subsidiaries. Financing arrangements under
which Twin is the borrower restrict the payment of dividends and the making of
loans, advances or other distributions to Twinlab except in certain limited
circumstances. See "Dividend Policy" and "Description of Certain Indebtedness."
 
YEAR 2000
 
     The Company recognizes the importance of ensuring that neither its
customers nor its business operations are disrupted as a result of Year 2000
software failures. The Company is communicating with customers, suppliers,
financial institutions and other vendors with which it does business to
coordinate Year 2000 conversion efforts. At the present time, the Company
believes that its systems are substantially Year 2000 compliant and does not
expect Year 2000 issues to materially effect its products, services, competitive
position or financial performance. However, there can be no assurance that this
will be the case. The ability of third parties with whom the Company transacts
business to adequately address their Year 2000 issues is outside the Company's
control. There can be no assurance that the failure of such third parties to
adequately address their respective Year 2000 issues will not have a material
adverse effect on the Company's business, financial condition, cash flows and
results of operations.

                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of the 4,000,000 shares of
Common Stock offered by the Company hereby (using an assumed offering price of
$38.875 per share) are estimated to be approximately $147.7 million, after
deducting the estimated underwriting discounts and commissions and offering
expenses payable by the Company. The Company intends to use $56.5 million of the
net proceeds from the Offerings to pay the purchase price of the Bronson
Acquisition (including related fees and expenses). In addition, the Company
intends to use approximately $40.1 million of the net proceeds from the
Offerings to redeem $35.0 million in outstanding principal amount of Notes at a
redemption price equal to 109 1/2% of the principal amount thereof plus accrued
and unpaid interest thereon to the date of redemption (the "Redemption"), and
approximately $5.6 million to reduce outstanding borrowings under the Company's
Revolving Credit Facility (including accrued and unpaid interest thereon). The
remaining net proceeds from the Offerings will be used for working capital and
other general corporate purposes. Borrowings under the Revolving Credit Facility
were used for general corporate purposes, including the payment of the cash
portion of the purchase price of Changes International. See "Prospectus
Summary -- Business Strategy -- Supplement Internal Growth Through Strategic
Acquisitions" and "-- Recent Trends and Developments -- Bronson Acquisition."
Pending the use of the net proceeds for such purposes, the Company will invest
such proceeds in short-term, interest-bearing investments.
    
 
     In the event the Bronson Acquisition is not consummated, the Company
intends to use the resulting excess net proceeds from the Offerings for working
capital and other general corporate purposes, including to pursue acquisitions.
See "Risk Factors -- Uncertainty Related to Acquisitions; Broad Discretion in
Use of Proceeds."
 
     For information with respect to the Revolving Credit Facility and the Notes
(including applicable interest rates and the maturity dates thereof), see
"Description of Certain Indebtedness."
 
     The Company will not receive any proceeds from the sale of shares of Common
Stock offered by the Selling Stockholders.

                                DIVIDEND POLICY
 
     The Company currently intends to retain earnings to finance its operations
and future growth and does not anticipate paying any cash dividends on its
Common Stock in the foreseeable future. Twinlab conducts its business through
its direct and indirect subsidiaries and has no operations of its own. The
principal assets of Twinlab are the capital stock of its direct and indirect
subsidiaries, Twin, ARP and Changes International. Accordingly, Twinlab has no
independent means of generating revenues. As a holding company, Twinlab's
internal sources of funds to meet its cash needs, including payment of expenses,
are dividends and other permitted payments from its direct and indirect
subsidiaries. Financing arrangements under which Twin is the borrower restrict
the payment of dividends and the making of loans, advances or other
distributions to Twinlab, except in certain limited circumstances. See
"Description of Certain Indebtedness." The payment of cash dividends in the
future will depend upon, among other things, the Company's results of
operations, financial condition, cash requirements and other factors deemed
relevant by the Company's Board of Directors.
 
                                 CAPITALIZATION
 
   
     The following table sets forth the actual capitalization of the Company as
of December 31, 1997, and as adjusted to reflect the sale by the Company in the
Offerings of 4,000,000 shares of Common Stock at an assumed price of $38.875 per
share and the application by the Company of the estimated net proceeds therefrom
(including the consummation of the Bronson Acquisition) as if they occurred on
December 31, 1997. This table should be read in conjunction with "Management's

(a) The Blechman Brothers, their parents, David and Jean Blechman, Stephen L.
    Welling, the President of the Nature's Herbs division of the Company
    (collectively, the "Stockholders"), GEI and certain other parties entered
    into a Stock Purchase and Sale Agreement, dated as of March 5, 1996, as
    amended (the "Acquisition Agreement"), pursuant to which, among other
    things, on May 7, 1996 (i) GEI acquired 48% of the Common Stock of Twinlab
    for aggregate consideration of $4.8 million and shares of non-voting junior
    redeemable preferred stock of Twinlab (the "Junior Preferred Stock") for
    aggregate consideration of $37.0 million, (ii) certain other investors
    acquired 7% of the Common Stock of Twinlab for aggregate consideration of
    $0.7 million and shares of nonvoting senior redeemable preferred stock of
    Twinlab (the "Senior Preferred Stock," and, together with the Junior
    Preferred Stock, the "Preferred Stock") for aggregate consideration of $30.0
    million, (iii) the Senior Executive Officers exchanged certain of their
    shares of common stock of Twin (formerly known as Natur-Pharma Inc.) for 45%
    of the outstanding shares of Common Stock of Twinlab valued at $4.5 million,
    (iv) Twinlab purchased all of the remaining shares of common stock of Twin
    from the Stockholders for cash, resulting in Twin becoming a wholly owned
    subsidiary of Twinlab. The total cash consideration that the Stockholders
    received was approximately $212.5 million, the majority of which was paid to
    David and Jean Blechman. The transactions described above are hereinafter
    referred to as the "Acquisition." Concurrently with the consummation of the
    Acquisition, the Company entered into a credit facility (the "Original
    Credit Facility") (which provided for a term loan facility in the amount of
    $53.0 million and a revolving credit facility in the amount of $15.0
    million) and issued $100.0 million principal amount of 10 1/4% Senior
    Subordinated Notes due 2006 (the "Note Offering"; and, collectively with the
    Acquisition and the Original Credit Facility, the "Transactions"). The net
    cash proceeds of the Note Offering were used, together with borrowings under
    the Original Credit Facility, the proceeds from the issuance of the Common
    Stock and Preferred Stock of Twinlab and available cash of the Company, to
    finance the Acquisition, to refinance approximately $7.0 million aggregate
    principal amount of debt of the Company and to pay related fees and
    expenses. The Company consummated an initial public offering of 8,500,000
    shares of Common Stock in November 1996 (the "IPO"). The net proceeds of the
    IPO of approximately $93.7 million, together with available cash resources
    of the Company and approximately $20.0 million of borrowings under the
    Revolving Credit Facility, were used to repay all of the Company's
    outstanding indebtedness under the Original Credit Facility and to redeem
    all of the outstanding shares of Preferred Stock. See Note 1 to the

    Prospectus.
 
(b) Reflects $15.3 million of nonrecurring non-competition agreement expense and
    $0.4 million of Transaction expenses.
 
(c) Basic and diluted income per share has been computed by dividing net income
    (and pro forma income before extraordinary item and pro forma net income for
    1995 and 1996), after reduction for Preferred Stock dividends, by the
    applicable weighted average shares outstanding.
 
   
(d) Supplemental basic and diluted net income per share for the year ended
    December 31, 1997, after giving effect to the Redemption, would be $0.89.
    Such calculation assumes the Redemption occurred on January 1, 1997 and
    includes the assumed issuance of 1,033,000 shares of Common Stock required
    to effect the Redemption and the elimination of interest expense and
    amortization of deferred finance costs, net of tax, relating to the redeemed
    Notes.
    
 
(e) Diluted weighted average shares outstanding for 1993 through 1996 represents
    the number of equivalent shares outstanding after giving retroactive effect
    to Twinlab's 18.5 for 1 stock split (effected in the form of a stock
    dividend) and assumes that the 10,175,000 shares of Common Stock issued in
    connection with the Acquisition and the 8,500,000 shares of Common Stock
    issued in connection with the Company's IPO were outstanding. See Notes to
    the Consolidated Financial Statements of the Company included elsewhere in
    this Prospectus.
 
(f) Prior to May 1996, the Company consisted of "S" corporations and,
    accordingly, federal and state taxes were generally paid at the shareholder
    level only. Upon consummation of the Transactions, the Company eliminated
    its "S" corporation status and, accordingly, became subject to federal and
    state income taxes.
 
(g) Represents the write-off of previously deferred finance costs incurred in
    connection with the Original Credit Facility (the "Extraordinary Item").
 
(h) The unaudited pro forma results of operations assume the Transactions and
    the subsequent IPO occurred on January 1, 1995, and exclude the effect of
    (i) the nonrecurring non-competition agreement expense, (ii) the Transaction
    expenses, (iii) the Extraordinary Item and (iv) the dividends paid on the
    Preferred Stock which was redeemed with a portion of the net proceeds of the
    IPO, and reflects the additional interest expense relating to the financing
    of the Acquisition and the change in tax status described in Note (f) above.
    This data has been prepared for comparative purposes only and does not
    purport to represent what the Company's actual results of operations would
    have been had the Transactions and the subsequent IPO in fact occurred on
    January 1, 1995.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion and analysis should be read in conjunction with
"Selected Historical Financial Data" and the audited Consolidated Financial
Statements of the Company and the notes thereto included elsewhere in this
Prospectus.
 
RESULTS OF OPERATIONS
 
     The Company operates in one business segment, the manufacture and marketing
of brand name nutritional supplements. Within this segment, the Company operates
in three primary business areas: the TWINLAB division, the herbal products
division, and the network marketing division. Products sold by the TWINLAB
division include vitamins, minerals, amino acids, fish and marine oils, sports
nutrition products and special formulas primarily under the TWINLAB brand name.
The herbal products division includes a full line of herbal supplements and
phytonutrients marketed by the Nature's Herbs division and a full line of herb
teas marketed by the Alvita division. The Company's network marketing activities
are conducted through Changes International, which was acquired by the Company
in November 1997. The Company's publishing activities are conducted through ARP.
 
     The following table sets forth, for the periods indicated, certain
historical income statement and other data for the Company and also sets forth
certain of such data as a percentage of net sales.

</TABLE>
 
FISCAL 1997 COMPARED TO FISCAL 1996
 
     Net Sales.  Net sales for fiscal 1997 were $213.2 million, an increase of
$43.1 million, or 25.4%, as compared to net sales of $170.1 million for fiscal
1996. The 25.4% increase was attributable to increased sales in each of the
Company's product categories other than publishing, partially offset by an
increase in sales discounts and allowances which was primarily due to the
Company's increased sales volume. Changes International contributed gross sales
of $7.0 million after its acquisition in November 1997. Gross sales of TWINLAB
products contributed $174.9 million, an increase of $24.5 million or 16.3% as
compared to $150.4 million for fiscal 1996. This increase was primarily due to
the expansion of established accounts, increased sales of existing products, new
product introductions and product specific advertising. Herbal supplements and
phytonutrients contributed $41.1 million, an increase of $18.0 million, or
78.2%, as compared to $23.1 million for fiscal 1996 and herb teas contributed
$8.4 million as compared to $8.1 million for fiscal 1996. The gross sales
increase in herbal supplements and phytonutrients was primarily due to the
expansion of established accounts in domestic health food stores, improved
business development in the mass market channel of distribution, increased sales
of existing products and new product introductions.
 
     Gross Profit.  Gross profit for fiscal 1997 was $92.3 million, which
represented an increase of $22.1 million or 31.4%, as compared to $70.2 million
for fiscal 1996. Gross profit margin was 43.3% for 1997, as
 
                                       23
<PAGE>   25
 
compared to 41.3% for fiscal 1996. The overall increase in gross profit was
primarily attributable to the Company's higher sales volume for fiscal 1997 as
compared to fiscal 1996. The increase in gross profit margin for fiscal 1997 as
compared to fiscal 1996 was due primarily to a more favorable product mix to
higher margin sports nutrition and special formula products, to higher gross
profit margins on recently introduced new product formulations and product line
extensions, to lower unit manufacturing overhead as a result of overhead costs
increasing at a rate lower than sales and to higher gross margins on sales
through the network marketing business, partially offset by an increase in sales
discounts and allowances.
 
     Operating Expenses.  Operating expenses were $43.4 million for fiscal 1997,
representing an increase of $12.6 million, or 41.1%, as compared to $30.8
million for fiscal 1996. As a percent of net sales, operating expenses increased
from 18.1% for fiscal 1996 to 20.4% for fiscal 1997. The increase in operating
expenses and operating expenses as a percent of net sales was primarily
attributable to increased selling and marketing expenses and higher general and
administrative expenses due to increased levels of promotional and sales
activities, including commission expense relating to Changes International, and
the hiring of additional administrative staff.
 
     Income from Operations.  Income from operations was $48.8 million for
fiscal 1997, representing an increase of $9.3 million or 23.8% as compared to
$39.5 million for fiscal 1996. Income from operations margin decreased to 22.9%
of net sales for fiscal 1997, as compared to 23.2% of net sales for fiscal 1996.
The increase in income from operations for 1997 was primarily due to the
Company's higher sales volume together with higher gross margins, offset in part
by higher operating expenses. The decrease in operating margin as a percent of
net sales in 1997 was due to higher operating expenses as a percent of net
sales, partially offset by increased sales volumes together with higher gross
margins.
 
     Other Expense.  Other expense was $12.1 million for fiscal 1997, as
compared to $25.1 million for fiscal 1996. The net decrease of $13.0 million is
primarily attributable to $15.7 million of nonrecurring non-competition
agreement expense and transaction expenses which were incurred in 1996 in
connection with the Transactions offset by an increase in net interest expense
of $2.7 million resulting from increased borrowings during 1997.
 
FISCAL 1996 COMPARED TO FISCAL 1995
 
     Net Sales.  Net sales for fiscal 1996 were $170.1 million, an increase of
$21.4 million, or 14.3%, as compared to net sales of $148.7 million for fiscal
1995. The 14.3% increase was attributable to increased sales in each of the
Company's product categories, partially offset by an increase in sales discounts
and allowances which was primarily due to the Company's increased sales volume.
Gross sales of TWINLAB products contributed $150.4 million, an increase of $18.2
million, or 13.7%, as compared to $132.2 million for fiscal 1995. This increase
was primarily due to increased demand for products sold under the TWINLAB brand
name, which increase was due in substantial part to the successful introduction
of a number of new special formula and sports nutrition products. Herbal
supplements and phytonutrients contributed $23.1 million, an increase of $3.3
million, or 16.4%, as compared to $19.8 million for fiscal 1995 and herb teas
contributed $8.1 million, an increase of $2.3 million, or 41.5%, as compared to
$5.8 million for fiscal 1995. The gross sales increase in both herbal
supplements and phytonutrients and herb teas was primarily due to increased
demand for both Nature's Herbs and Alvita products, which increase was due in
part to the successful introduction of new products, continued strong consumer
interest in existing products and increased penetration of both Nature's Herbs
and Alvita products into domestic health food stores. Publishing contributed
gross sales of $5.4 million for fiscal 1996, as compared to $4.8 million for
fiscal 1995.
 
     Gross Profit.  Gross profit for fiscal 1996 was $70.2 million, which
represented an increase of $11.4 million, or 19.5%, as compared to $58.8 million
for fiscal 1995. Gross profit margin was 41.3% for fiscal 1996 as compared to
39.5% for fiscal 1995. The overall increase in gross profit was primarily
attributable to the Company's higher sales volume for fiscal 1996 as compared to
fiscal 1995. The increase in gross profit margin for fiscal 1996 as compared to
fiscal 1995 was due primarily to higher gross profit margins on recently
introduced new product formulations and lower unit manufacturing overhead as a
result of overhead costs
 
                                       24
<PAGE>   26
 
increasing at a rate lower than sales due to manufacturing efficiencies,
partially offset by an increase in sales discounts and allowances.
 
     Operating Expenses.  Operating expenses were $30.8 million for fiscal 1996,
representing an increase of $3.6 million, or 13.2%, as compared to $27.2 million
for fiscal 1995. As a percent of net sales, operating expenses declined from
18.3% for fiscal 1995 to 18.1% for fiscal 1996. The increase in operating
expenses was primarily attributable to increased selling and advertising
expenses and higher operating expenses resulting from the Company's increased
sales for fiscal 1996. The decline in operating expenses as a percent of net
sales was due to the Company's ability to maintain its research and development
expenditures and a substantial portion of its general and administrative costs
at approximately the same level as in fiscal 1995, while substantially
increasing the Company's sales volume.
 
     Income from Operations.  Income from operations was $39.5 million for
fiscal 1996, representing an increase of $7.9 million, or 24.8%, as compared to
$31.6 million for fiscal 1995. Income from operations margin increased to 23.2%
of net sales for fiscal 1996, as compared to 21.3% of net sales for fiscal 1995.
The increase in income from operations and income from operations margin was
primarily due to the Company's higher sales volume, higher gross margins and
lower operating expenses as a percent of net sales for fiscal 1996.
 
     Other Income (Expense).  Other expense was $25.1 million for fiscal 1996,
as compared to $1.1 million for fiscal 1995. The net increase is primarily
attributable to a nonrecurring $15.3 million charge relating to the write-off of
certain non-competition agreements and a $9.1 million increase in interest
expense which resulted from increased borrowings.
 
     Income taxes.  The Company consisted of "S" corporations for the year ended
December 31, 1995, and through the consummation of the Acquisition on May 7,
1996. Accordingly, federal and state taxes were generally paid at the
shareholder level only. The provision for income taxes through May 7, 1996 and
for the year ended December 31, 1995, represented state taxes for New York,
which imposes a corporate tax for all income in excess of $0.2 million. Upon
consummation of the Transactions, the Company eliminated its "S" corporation
status and, accordingly, became subject to federal and state income taxes.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     For fiscal 1997, cash provided by operating activities was $11.4 million,
as compared to $25.5 million for fiscal 1996 and $26.8 million for fiscal 1995.
The decrease in fiscal 1997 compared to fiscal 1996 was primarily due to higher
accounts receivable and inventory balances due to higher levels of sales volume
as well as the timing of payments of accrued expenses and other current
liabilities. The decrease in fiscal 1996 compared to fiscal 1995 was primarily
due to higher interest expense, substantially offset by higher income from
operations. Cash used in financing activities was $6.3 million for fiscal 1997,
and represented repayment of certain outstanding indebtedness. Cash used in
financing activities for fiscal 1996 was $28.0 million, reflecting the net cash
effect of the Transactions (including the payments to the Stockholders made
pursuant to the Acquisition) and the IPO, and the application of the proceeds
therefrom, the repayment of $6.0 million of outstanding indebtedness and
distributions of $8.9 million to the Stockholders prior to the consummation of
the Acquisition. Cash used in financing activities for fiscal 1995 was $24.0
million and primarily consisted of distributions to the Stockholders of $23.5
million.
 
     Capital expenditures in 1997 were $3.8 million ($3.1 million of which was
for equipment that was subsequently sold and leased back) and $2.3 million and
$2.6 million for fiscal 1996 and 1995, respectively. Historical capital
expenditures were primarily used to purchase production equipment, expand
capacity and improve manufacturing efficiency. Capital expenditures are expected
to be approximately $17.0 million during fiscal 1998, of which approximately
$13.0 million will be used to expand the Company's Utah Facility (approximately
$8.0 million of which will be financed by a nine-month construction loan that
will be converted to a fifteen-year mortgage) and the remainder of which will be
used primarily to purchase manufacturing equipment and computer hardware and
software. The Company estimates that its historical level of maintenance capital
expenditures has been approximately $0.5 million per fiscal year.
 
                                       25
<PAGE>   27
 
     On November 12, 1997, the Company acquired Changes International for a
purchase price (including fees and expenses) of approximately $13.7 million,
consisting of $7.9 million in cash and 312,500 shares of Twinlab Common Stock.
The cash portion of the purchase price was financed through borrowings under the
Company's Revolving Credit Facility. Changes International operates as a network
marketer of nutritional supplements through independent distributors located
primarily throughout the United States and Canada. The acquisition was recorded
using the purchase method of accounting.
 
     Twinlab has no operations of its own and accordingly has no independent
means of generating revenue. As a holding company, Twinlab's internal sources of
funds to meet its cash needs, including payment of expenses, are dividends and
other permitted payments from its direct and indirect subsidiaries. The
Indenture relating to the Notes and the Revolving Credit Facility impose upon
the Company certain financial and operating covenants, including, among others,
requirements that the Company maintain certain financial ratios and satisfy
certain financial tests, limitations on capital expenditures and restrictions on
the ability of the Company to incur debt, pay dividends or take certain other
corporate actions. The Company was in compliance with all such covenants as of
December 31, 1997.
 
     Management believes that the Company has adequate capital resources and
liquidity to meet its borrowing obligations, fund all required capital
expenditures and pursue its business strategy for at least the next 18 to 24
months. The Company's capital resources and liquidity are expected to be
provided by the Company's cash flow from operations, borrowings under the
Revolving Credit Facility and the proceeds from the Offerings. As of December
31, 1997, approximately $36.3 million of borrowings were available under the
Revolving Credit Facility for working capital requirements and general corporate
purposes.
 
     One of the Company's business strategies is to actively pursue acquisition
opportunities that complement or extend its existing products, expand its
distribution channels or are compatible with its business philosophy and
strategic goals. Future acquisitions could be financed by internally generated
funds, bank borrowings, public offerings or private placements of equity or debt
securities, or a combination of the foregoing. Up to $35.0 million of borrowings
under the Revolving Credit Facility is available to fund acquisitions subject to
certain conditions and reductions (approximately $21.3 million of which was
available as of December 31, 1997). There can be no assurance that the Company
will be able to make acquisitions on terms favorable to the Company and that
funds to finance an acquisition will be available or permitted under the
Company's financing instruments.
 
     On March 17, 1998, the Company entered into a definitive agreement to
acquire substantially all of the assets and assume certain liabilities of
Bronson. The Company expects that the closing of the Bronson Acquisition will
occur during the second quarter of fiscal 1998. Bronson's net sales and
operating income for the fiscal year ended December 31, 1997, were approximately
$32.1 million, and $9.5 million, respectively. The purchase price is $55.0
million in cash, subject to certain adjustments, which the Company intends to
finance with a portion of the net proceeds of the Offerings. See "Prospectus
Summary -- Recent Trends and Developments -- Bronson Acquisition" and "Risk
Factors -- Uncertainty Related to Acquisitions; Broad Discretion in Use of
Proceeds."
 
     In addition, the Company intends to use approximately $40.1 million of the
net proceeds from the Offerings to pay for the Redemption and approximately $5.6
million to reduce outstanding borrowings under the Company's Revolving Credit
Facility (including accrued and unpaid interest thereon). In connection with the
Redemption, the Company will record an extraordinary charge of approximately
$2.9 million (net of tax benefit of approximately $1.8 million) relating to the
payment of premiums on the Notes and the write-off of a pro rata portion of
deferred finance costs.
 
     The Company is currently considering the possibility of making an offer
(the "Offer") to purchase for cash all Notes not otherwise purchased in the
Redemption. The Company would finance any such Offer with borrowings under a new
bank credit facility, any remaining excess proceeds of the Offerings, available
cash, or any combination of the foregoing. There can be no assurance that the
Company will be in a position to enter into a new bank credit facility for the
purposes of making an Offer or that other financing will be available. Moreover,
the Company's determination to make an Offer would be subject to financial,
market and other conditions and there can be no assurance that the Company will
make an Offer. Accordingly, the possibility
                                       26
<PAGE>   28
 
that an Offer may be made or consummated should not be considered by prospective
purchasers of the Common Stock.
 
RECENT TRENDS
 
     In the first quarter of 1998, the Company received a substantial increase
in orders for its herbal supplement products, including a significant increase
in orders from Wal-Mart for herbal products which are being sold under
Wal-Mart's proprietary Spring Valley brand name. This increase is due to
increased demand at the retail level and to the fact that the number of SKU's
sold under this brand name at Wal-Mart more than doubled during the first
quarter of 1998. The Company has made several adjustments to its operations to
accommodate this increased demand for its herbal products, including the use of
production capacity at the New York Facility to produce herbal supplement
products and the installation of additional manufacturing equipment at both the
New York and Utah Facilities. As a result of these operational adjustments and
the Company's decision to reduce promotions offered to distributors during the
first quarter of 1998, the Company's mix of product sales during the first
quarter of 1998 will differ substantially from the product mix in the comparable
period in 1997. For the first quarter of 1998, herbal supplements will represent
a substantially greater portion of the Company's total net sales, and sales of
vitamins, minerals and nutritional supplements products will represent a smaller
percentage of total net sales and decline significantly from the comparable
period in 1997. Nevertheless, the Company anticipates that its overall growth
rate in net sales in the first quarter of 1998 will be comparable to that
achieved in the first quarter of 1997, as the increased sales of herbal products
will more than offset the decreased sales of vitamins, minerals and nutritional
supplements (all of the foregoing first quarter comparisons exclude the impact
of Changes International). The Company believes that there has been no material
decline in retail sales of its vitamin, mineral and nutritional supplement
products during the first quarter of 1998, as there has been adequate inventory
of its products in the distribution channel. The Company plans to adjust its
production mix during the second quarter of 1998 to increase the production of
vitamins, minerals and nutritional supplements compared to the first quarter of
1998, as additional capacity comes on line and production schedules are
adjusted, and expects to realize increased sales of these products during the
second quarter of 1998 as compared to the first quarter of 1998.
 
IMPACT OF INFLATION
 
     Generally, the Company has been able to pass on inflation-related cost
increases; consequently, inflation has not had a material impact on the
Company's historical operations or profitability.
 
RECENT FINANCIAL ACCOUNTING STANDARDS BOARD STATEMENTS
 
     Recent pronouncements of the Financial Accounting Standards Board, which
are not required to be adopted at this date, include Statement of Financial
Accounting Standards ("SFAS") No. 130, "Reporting Comprehensive Income", SFAS
No. 131, "Disclosures about Segments of an Enterprise and Related Information"
and SFAS No. 132, "Employers' Disclosures about Pensions and Other
Postretirement Benefits." These pronouncements are not expected to have material
impact on the Company's financial statements.
 
YEAR 2000
 
     The Company recognizes the importance of ensuring that neither its
customers nor its business operations are disrupted as a result of Year 2000
software failures. The Company is communicating with customers, suppliers,
financial institutions and other vendors with which it does business to
coordinate Year 2000 conversion efforts. At the present time, the Company
believes that its systems are substantially Year 2000 compliant and does not
expect Year 2000 issues to materially affect its products, services, competitive
position or financial performance. However, there can be no assurance that this
will be the case. The ability of third parties with whom the Company transacts
business to adequately address their Year 2000 issues is outside the Company's
control. There can be no assurance that the failure of such third parties to
adequately address their respective Year 2000 issues will not have a material
adverse effect on the Company's business, financial condition, cash flows and
results of operations.

                                    BUSINESS
 
GENERAL
 
     The Company is one of the leading manufacturers and marketers of brand name
nutritional supplements sold through domestic health food stores and is also
engaged in the sale of its products through national and regional drug store
chains, supermarkets, mass market retailers and Changes International, its
recently acquired network marketing company. The Company produces a full line of
nutritional supplements and offers the broadest product line in the industry
with more than 940 products and 1,700 stockkeeping units (SKU's). The Company's
product line includes vitamins, minerals, amino acids, fish and marine oils,
sports nutrition products and special formulas marketed under the TWINLAB
trademark, a full line of herbal supplements and phytonutrients marketed under
the Nature's Herbs and HealthCare Naturals trademarks and herb teas marketed
under the Alvita trademark. In addition, the Company markets a line of
nutritional supplements exclusively through Changes International. The Company
emphasizes the development and introduction of high-quality, unique
nutraceuticals and other products in response to emerging trends in the
nutritional supplement industry. The Company's broad product line, strong
history of new product introductions and innovations, superior marketing and
advertising programs and premium product quality have established TWINLAB,
Nature's Herbs and Alvita as leading and widely-recognized brands in the
nutritional supplement industry.
 
     Under the leadership of the Blechman family, Twinlab has achieved increased
net sales and income from operations every year since 1990. Since 1993, the
Company's net sales and income from operations have grown at compound annual
growth rates of 20.9% and 30.9%, respectively. For the year ended December 31,
1997, the Company generated net sales, net income and net income per share of
$213.2 million, $22.7 million and $0.84, respectively.
 
     The Company's products target consumers who utilize nutritional supplements
in their daily diet and who demand premium quality ingredients in a broad
variety of dosages and delivery methods. To reach the broadest possible consumer
market, the Company has developed a multi-branded and multi-channel distribution
strategy, consisting of the following categories:
 
   
     - Health Food Stores -- The Company's TWINLAB, Nature's Herbs and Alvita
       brand products are sold through a network of approximately 60
       distributors to nearly 11,000 health food stores and other selected
       retail outlets. The health food store channel of distribution has
       continued to experience significant growth in recent years as national
       chains, including those which sell the Company's products, such as GNC,
       WFM, Wild Oats and other industry participants continue to add stores in
       new and existing markets. The Company believes that it has a competitive
       advantage in the health food store channel due to the high quality of its
       products which is a direct result of its use of premium ingredients, its
       modern manufacturing facilities and its comprehensive quality control
       procedures. Sales to the health food store channel, primarily through
       distributors, continue to represent the Company's largest market totaling
       approximately $171.6 million, or approximately 80.5%, of the Company's
       net sales in 1997. The Company believes that its products have a presence
       in over 90% of the health food stores in the United States, but that only
       approximately 12% of such stores carry a comprehensive line of the
       Company's products. Management believes that the continued expansion of
       health food store retail outlets and the strong growth characteristics of
       the nutritional supplement industry, combined with health food retailers'
       success with the Company's product lines, provide Twinlab with
       significant opportunities to increase sales in the health food store
       channel.
    
 
     - Mass Market Retailers -- The Company continues to increase its
       penetration of the fast growing mass market retail channel, which
       consists of drug store chains, supermarkets and other mass merchandisers.
       The Company is currently a provider of private label herbal products to
       Wal-Mart, which are being sold under Wal-Mart's proprietary Spring Valley
       brand name. The Company also sells its products through national and
       regional drug store and supermarket chains, such as Rite Aid Corporation,
       Duane Reade Inc., American Stores, Inc. and Albertson's, Inc., under its
       established TWINLAB, HealthCare Naturals and Alvita brand names. The
       Company believes that the mass market distribution channel
 
                                       28
<PAGE>   30
 
   
       affords significant growth opportunities and intends to continue to
       introduce new products and new brands designed specifically for customers
       in this channel. During 1998, the Company plans to introduce a line of
       sports nutrition products under a new proprietary brand name which will
       be sold exclusively in the mass market channel. Approximately $14.0
       million or 6.6% of the Company's 1997 net sales were attributable to mass
       market retailers compared to $3.4 million or 2.0% in 1996. Due to a
       variety of recent programs initiated by the Company, Twinlab expects to
       experience significant growth in this category during fiscal 1998. See
       "Prospectus Summary -- Recent Trends and Developments -- First Quarter
       Trends."
    
 
     - Network Marketing -- Through Changes International, a network marketing
       company which the Company acquired in November 1997, Twinlab develops,
       markets and sells vitamins, herbs and nutritional supplements exclusively
       under the Changes brand name. Changes International operates through a
       large sales force of independent distributors located throughout the
       United States and Canada who sell directly to consumers. Changes
       International's products include Changes Relief, an advanced supplement
       that nutritionally supports healthy bone and joint functions, and
       Perfor-Max, an antioxidant formula containing grapeseed extract, pine
       bark extract and tumeric. All of Changes International's products are
       specially formulated and packaged exclusively for the network marketing
       channel and are not intended for sale to retail outlets. The Company is
       making a significant investment to enhance Changes International's
       management team, infrastructure and management information systems in an
       effort to expand its distributor and customer base and to increase sales
       in this distribution channel. During 1998, the Company intends to more
       than double the size of Changes International's nutritional supplement
       line, beginning with the introduction of eight new products during the
       first half of 1998. Changes International was founded in 1994 and
       generated gross sales of $41.5 million in 1997 ($7.0 million in fiscal
       1997 after its acquisition by the Company).
 
BUSINESS STRATEGY
 
     The Company's strategy is to continue to increase sales and profits by
furthering its leadership position in the sale of vitamins, herbs and
nutritional supplements to the health food store channel while continuing to
increase sales and market share in the mass market and network marketing
channels. The Company also intends to seek opportunities to enter other channels
of distribution, including catalog distribution. Twinlab plans to implement this
strategy both by capitalizing on the strength of its established brands as well
as through the development and introduction of new brands. In addition, the
Company expects to continue to develop and introduce new products and product
innovations for each of its distribution channels, to increase its penetration
of foreign markets and to provide the advertising, marketing, operational and
personnel support necessary to grow its businesses. Twinlab intends to achieve
these goals while continuing its past emphasis on its financial performance and
the overall efficiency of its operations. Specifically, the Company seeks to:
 
     Further Develop Portfolio of Brands -- Twinlab has developed a portfolio of
core brands which are among the most recognized in the vitamin and nutritional
supplement industry. The Company intends to continue to nurture and extend the
reach of its TWINLAB, Nature's Herbs and Alvita brands in the health food
distribution channel while furthering the development of its portfolio of
private label and proprietary brands, including the HealthCare Naturals and
Changes brands, targeted to the mass market retail and network marketing
channels. During 1998, the Company plans to introduce a line of sports nutrition
products under a new proprietary brand name which will be sold exclusively in
the mass market channel. As in the past, the Company will continue to promote
its brands through strong marketing and advertising programs. Management
believes that Twinlab has one of the largest marketing and advertising budgets
as a percentage of sales in the nutraceutical industry and that the strong brand
name recognition of its products is, in part, a direct result of this support.
In fiscal 1997, the Company spent $15.9 million, an increase of 25.1% over
fiscal 1996, on marketing and advertising to promote its products. The Company
has budgeted $20.5 million for marketing and advertising expenses in fiscal
1998, a 29.2% increase over fiscal 1997.
 
     Further Develop Multiple Channels of Distribution -- The Company intends to
continue to increase its penetration of the health food store channel, expand
its mass market retail and network marketing businesses, and enter additional
distribution channels, such as catalog distribution, through internal growth and
selective
                                       29
<PAGE>   31
 
acquisitions. See "Recent Trends and Developments -- Bronson Acquisition." By
utilizing a multiple distribution channel approach, the Company believes it will
be well positioned to also reach customers who historically have not shopped in
health food stores.
 
   
     Continue to Introduce New Products and Product Innovations -- A cornerstone
of the Company's success has been its ability to rapidly utilize recent
scientific and medical findings in its new product development efforts. The
Company has consistently been among the first in its industry to introduce new
products and product innovations which anticipate and meet customer demands for
newly identified nutritional supplement benefits. As part of its ongoing
research and development effort, the Company maintains an extensive database and
actively researches and monitors a wide variety of publications containing
scientific and medical research. The Company's geographically diverse network of
distributors allows Twinlab to achieve immediate and broad distribution for new
product launches. From 1991 through 1997, the Company introduced over 560
products, with over 100 new products introduced in 1997 alone. Net sales during
1997 from new products introduced in 1997 were approximately $17.7 million, or
approximately 8.3% of net sales. In 1998, the Company expects to introduce over
100 new products in the health food store and mass market retail channels, 18 of
which have already been introduced, and plans to more than double the number of
products offered by Changes International.
    
 
   
     Increase Penetration of Foreign Markets -- Management believes that there
are substantial opportunities for the Company to expand its presence in foreign
markets. As part of its continuing efforts to increase international sales, the
Company recently hired a Director of International Sales. The Company's
international sales force is supported by a network of 37 overseas distributor
organizations, serving 56 foreign countries. Approximately 5.1%, or $10.9
million, of the Company's net sales in 1997 were derived from international
sales originating from overseas distributor organizations. The Company presently
has distribution agreements covering fourteen western European countries,
including Great Britain, France, Belgium, the Netherlands and the Scandinavian
countries; six eastern European countries, including Russia; nine Latin American
countries, including Mexico, Brazil and Argentina; eight Middle Eastern
countries, including Israel and Saudi Arabia; and several other countries in the
Far East and the Caribbean. The Company has also initiated new programs to
qualify distributors in Italy and China.
    
 
     Supplement Internal Growth Through Strategic Acquisitions -- The Company
actively pursues acquisition opportunities that will complement or extend its
existing product line, expand its distribution channels or would be compatible
with its business philosophy and strategic goals. The Company believes that its
leading and widely recognized brand names, broad distribution capabilities and
proven ability to generate sales of its products through successful marketing
programs provide it with a strategic advantage in identifying potential
acquisition candidates. In addition, the Company's success with past
acquisitions provides it with the knowledge to successfully integrate future
acquisitions into its operations. See "Prospectus Summary -- Recent Trends and
Developments -- Bronson Acquisition."
 
     Ongoing Investment in Personnel and Infrastructure -- The Company continues
to make significant investments in developing its management team and building
its infrastructure to support the growth of its businesses. The Company recently
hired several key individuals, including a new Chief Financial Officer, a
President of Mass Market Sales and a Director of International Sales, to enhance
its senior management team. As part of its ongoing efforts to maintain its
reputation for providing the highest quality products and services to its
customers, the Company continues to invest in its manufacturing and distribution
facilities and management information systems. The Company recently broke ground
on an approximately $13.0 million expansion of its state-of-the-art Utah
Facility. The total size of the Utah Facility will increase from 57,000 square
feet to approximately 143,000 square feet and will substantially increase the
Company's production capacity.
 
INDUSTRY
 
     Based on estimates in the Packaged Facts Report, the retail market for VMS
Products has grown at a compound annual rate of 15% from $3.7 billion in 1992 to
$6.5 billion in 1996. A large portion of this growth is attributable to an
increase in sales of supplements (primarily herbal products), which grew from
$570 million in 1992 to $2.3 billion in 1996. Growth in this category has been
fueled by the popularity of such herbs as
 
                                       30
<PAGE>   32
 
echinacea, garlic, ginseng, gingko and, more recently, saw palmetto and St.
John's wort. Packaged Facts forecasts 13.6% compound annual growth in the market
for VMS Products, including 25% compound annual growth in the market for
supplements, through the year 2001. In addition, according to Packaged Facts,
the retail market for sports nutrition products has grown at a compound annual
rate of 10.7% from approximately $585 million in 1992 to $880 million in 1996.

     Management believes this continued growth will be fueled by (i) favorable
demographic trends towards older Americans, who are more likely to consume
nutritional supplements; (ii) product introductions in response to new
scientific research findings supporting the positive health effects of certain
nutrients; (iii) the nationwide trend toward preventive medicine in response to
rising health care costs; (iv) increased consumer interest in herbs and
herb-related supplements; and (v) the heightened understanding and awareness of
healthier lifestyles and the connection between diet and health. Moreover,
although the industry has grown dramatically in recent years, there is still a
large untapped domestic market as only an estimated 50% of Americans currently
consume vitamins, herbs and nutritional supplements on a regular basis.
 
     Vitamin and nutritional supplements are sold through several channels of
distribution: health food stores, mass market retailers (drug store chains,
supermarkets and other mass merchandisers), and direct sales channels (including
network marketing and catalog distribution). In 1996, according to Packaged
Facts, the mass market channel accounted for approximately 45.8% of sales of VMS
Products, health food stores accounted for 38.2% of sales and the remaining
16.0% of sales were generated through direct selling, mail order and the
internet.
 
     The United States health food store market is comprised of approximately
11,000 stores, which are generally either independently owned or associated with
one of several regional or national chains, including GNC and WFM. According to
the Packaged Facts Report, nutritional supplements account for over 38% of a
typical health food store's sales. The health food store channel of distribution
has continued to experience growth in recent years as national chains, including
those which sell the Company's products, such as GNC, WFM and other industry
participants continue to add stores in new and existing markets. The growth in
the health food channel of distribution is partially attributable to the general
growth in natural product sales. Natural products are defined as products that
are minimally processed, environmentally friendly, largely or wholly free from
artificial chemicals and, in general, as close to their natural states as
possible.
 
     In the mass market channel, sales of vitamins, herbs and nutritional
supplements have generally grown in line with the growth in all channels due to
the proliferation of retail outlets and the expansion of SKU's offered by these
stores. However, within the mass market channel, mass merchandisers have
captured increasing market share from traditional drug store chains and
supermarkets. According to Packaged Facts, these mass merchandisers accounted
for 14.8% of total retail sales of VMS Products in 1996 compared to 11.5% in
1994. This compares to traditional drug store chains and supermarkets which
accounted for 31.0% and 34.6% of total retail sales of VMS Products in 1996 and
1994, respectively.
 
     Although growing, sales generated via direct selling, mail order and the
internet have not grown as quickly as sales in other channels of distribution.
According to Packaged Facts, sales via direct selling as a
 
                                       31
<PAGE>   33
 
percentage of total retail sales of VMS Products were 12.6% in 1996 compared to
13.1% in 1994. Sales via mail order and the internet were 3.4% and 4.2% of total
retail sales of VMS Products in 1996 and 1994, respectively. It is expected that
the market for internet sales will increase in the future as consumers become
more accustomed to ordering products online.

     Vitamins, Minerals and Amino Acids.  The vitamins, minerals and amino acids
category is comprised of a complete line of vitamins, minerals and amino acids
marketed under the TWINLAB brand name, including multivitamins and single-entity
vitamins (such as B-complex, C and E), minerals (such as calcium and magnesium)
and amino acids (such as glutamine and carnitine). These products are available
in a variety of delivery forms, including liquid, powder, capsule and tablet to
accommodate a variety of consumer preferences. This category targets a broad
array of health conscious consumers, with particular emphasis on consumers who
utilize nutritional supplements in their daily diet and who demand premium

     Sports Nutrition.  The sports nutrition category consists of a wide variety
of nutritional supplements designed for and targeted to athletes. These products
are specially formulated to help athletes achieve their personal physical goals
and enhance performance. Sports nutrition products include Hydra Fuel and Ultra
Fuel drinks, which replenish glucose and electrolytes depleted during strenuous
exercise; DietFuel, RxFuel and Ripped Fuel, which are marketed for the
preservation of lean body mass and the building of muscle mass, in conjunction
with a low fat diet and exercise program; Creatine Fuel, a university tested
supplement designed to increase body mass and muscular performance; and
Metabolift, a successful thermogenic formula. The Company plans to introduce a
line of sports nutrition products under a new proprietary brand name in the mass
market channel during fiscal 1998. The Company's sports nutrition products are
utilized by both amateur and professional athletes in a variety of competitive
sports. The Company believes that its strong sports nutrition business serves to
increase the Company's brand awareness among customers who, as they grow older,
are likely to shift their buying patterns to include the Company's vitamins,
herbs and other nutraceuticals.
 
     Special Formulas.  The special formulas category consists of a broad
assortment of products formulated with specific health conditions or objectives
in mind. Special formulas are primarily targeted to sophisticated users of
health related products, including regular customers of health food stores.
Examples include OcuGuard Plus with Lutein, which is formulated for nutritional
support for the eyes, Coenzyme Q(10), which is designed for cardiovascular
health, MaxiLIFE Glucosamine Sulfate and Chondroitin Sulfate Formula, which
nutritionally supports healthy bone and joint function, and the MaxiLIFE
Protector Series, the first premium supplement line to target the body's most
aging-prone areas. In addition, the Company sells a variety of fish and marine
oils in a number of different delivery forms which offer a multitude of
nutritional benefits, including favorable effects on cardiovascular health.
 
     Herbal Supplements and Phytonutrients.  Herbal supplements and
phytonutrients (produced from nutrients from botanical sources that are
considered to have medicinal properties) have become increasingly important
categories across all distribution channels. Through its Nature's Herbs product
line, the Company produces a full line of herbal supplements and phytonutrients
which offer natural alternatives to over-the-counter ("OTC") medications. The
Company manufactures and markets approximately 600 herbal and botanical
supplements which are produced at the Company's modern FDA registered Utah
Facility and sold under the Nature's Herbs and HealthCare Naturals brand names.
Nature's Herbs products include single herbs, such as saw palmetto, garlic,
ginseng and golden seal; traditional combinations, such as echinacea-golden
seal; standardized extracts, such as St. John's Wort Power, Gingko Power,
Bilberry Power and Milk Thistle Power sold under the POWER HERBS(R) brand name;
and natural HealthCare product formulations, such as Allerin and Coldrin.
Nature's Herbs recently introduced the first line of time-release herbs ever
developed. This advanced technology includes a unique micro-encapsulation
process that permits the Company's finely granulated herbal extracts to dissolve
gradually and consistently throughout the day. Nature's Herbs products are
packaged using the innovative FRESH CARE(R) System developed by the Company. The
FRESH CARE System is the first all-glass and antioxidant-protected herbal
packaging system that helps remove oxygen while locking out air, moisture and
light in order to maintain potency and to extend freshness. Management believes
that the association of the Nature's Herbs product line with TWINLAB's strong
name brand recognition and reputation for premium quality and service, combined
with the increased penetration of herbal supplements and phytonutrients in the
growing health food store channel of distribution, have contributed to the rapid
growth experienced by this product line. The HealthCare Naturals product line
also continues to gain strength and recognition in the mass market channel.
 
     Herb Teas.  Through its Alvita product line, the Company offers almost 200
herb teas in both single use bags and bulk. Alvita is a leading brand of herb
tea and is one of the most recognizable tea brands sold through health food
stores. Founded in 1922, Alvita is one of the nation's oldest herb tea
companies. Alvita purchases tea in bulk form, formulates blends of natural herb
teas and designs the packaging for its products. Alvita's teas are currently
blended and packaged by an independent contractor. Alvita teas include
Peppermint Leaf, Chamomile, Echinacea, Golden Seal, Ginger and Senna Leaf, as
well as new-age blends such as Chinese Green Tea, available in a choice of
citrus flavors, and TrimTime Thermogenic Diet Tea. Alvita markets its products
with an environmentally conscious theme by packaging bulk tea and tea bags in
paper and by not
 
                                       33
<PAGE>   35
 
utilizing shrink wrap for either its outer boxes or tea bags. Beginning in 1996,
Alvita launched a new line of herbal tea blends named Herbal Remeteas, including
Highland Lullaby, Manchurian Brain Blend, Jamaica Digesti Brew, and Canadian
Natur-Tussin. The Company believes that significant opportunities for product
line expansion exist in combining Alvita teas and other nutritional supplements
to create a new delivery form for traditional herbal supplements and
phytonutrients.
 
     Network Marketing.  Through Changes International, a network marketing
company which was acquired in November 1997, the Company develops, markets and
sells vitamins, herbs and nutritional supplements exclusively under the Changes
brand name. Changes International operates through a large sales force of
independent distributors located throughout the United States and Canada.
Changes International's products include Changes Relief, an advanced supplement
that nutritionally supports healthy bone and joint functions, and Perfor-Max, an
antioxidant formula containing grapeseed extract, pine bark extract and tumeric.
All of Changes International's products are specially formulated and packaged
and are manufactured by an independent contractor pursuant to the Company's
specifications solely for the network marketing channel and are not intended for
sale to retail outlets. During 1998, the Company intends to more than double the
size of Changes International's nutritional product line, beginning with the
introduction of eight new products during the first half of 1998.
 
     Publishing.  Through ARP, the Company publishes All Natural Muscular
Development, a high-quality physique and fitness magazine featuring a scientific
advisory board and contributors considered to be among the most accomplished and
knowledgeable in their respective fields. The magazine covers recent
developments and provides innovative information in the fields of training and
nutrition research, supplements, health, fitness and diet. This publication
serves as a useful vehicle to increase public awareness of the Company's
products and as an outlet for a portion of the Company's advertising program.
All Natural Muscular Development currently has a monthly paid circulation of
approximately 104,000 readers. ARP is planning to offer a line of All Natural
Muscular Development sports nutrition products which are expected to be
introduced in the second half of 1998. The Company also publishes health and
fitness related books and is exploring the introduction of new health and
fitness related products.
 
PRODUCT DEVELOPMENT
 
     The Company is recognized as an industry leader in new product development.
The Company closely monitors consumer trends and scientific research, and has
consistently introduced innovative products and programs in response thereto.
The Company's product development staff regularly studies over 50 different
health and nutrition periodicals, including the New England Journal of Medicine
and the Journal of the American Medical Association, in order to generate ideas
for new product formulations. Management believes that the Company's
introduction of new products has increased market share for both the Company and
its retail customers, and the Company intends to continue developing new
products and programs in the future. The Company was the first major nutritional
supplement manufacturer to introduce such industry-wide innovations as: an
all-capsule vitamin and mineral line that is well tolerated by allergy-prone
individuals; a complete line of amino acids and fish and marine oils; the most
advanced and complete array of antioxidants, including beta carotene, lutein,
lycopene, L-glutathione, N-acetyl cysteine (NAC), lipoic acid and an entirely
new class of antioxidants, including polyphenols, flavonoids and isoflavones;
concentrated Coenzyme Q(10); chondroitin sulfate; thermogenic products;
standardized herbal extracts guaranteeing potency (Certified Potency); the FRESH
CARE packaging system, designed to preserve potency and freshness; a full line
of Ayurvedic Indian herbal products; and a complete line of herb teas in single
use bag and bulk form. From 1991 through 1997, the Company introduced over 560
products, with over 100 new products introduced in 1997. Representative products
introduced in 1997 include MaxiLIFE SOY Cocktail, an advanced nutraceutical
drink rich in soy and isoflavones; Creatine Fuel Chews, chewable wafers
containing one gram of pure creatine monohydrate; St. John's Power 0.3%, a
concentrated extract of St. John's wort; and caffeine-free Chinese Green Tea, a
popular drink consumed worldwide for its health benefits. In 1998, the Company
expects to introduce over 100 new products in the health food and mass market
retail channels, 18 of which have already been introduced. Representative
products introduced in 1998 include MaxiLIFE Joint Food, an advanced
nutraceutical which supports healthy cartilage and joint function, and Triple
Whey Fuel, a product
 
                                       34
<PAGE>   36
 
containing high biological value whey protein. The Company also plans to more
than double the number of products offered through Changes International's
distribution network. The Company's research and development expenses were $1.1
million in 1997, 1996 and 1995.
 
SALES AND DISTRIBUTION
 
   
     The Company believes that its TWINLAB products have a presence in over 90%
of the health food stores in the United States, but that only approximately 12%
of such stores carry a comprehensive line of the Company's products. The Company
sells its products primarily through a network of approximately 60 distributors,
which service approximately 11,000 health food stores throughout the country and
selected retail outlets. Sales to domestic distributors represented
approximately 79.3% of the Company's net sales in 1997. The Company's
distributor customers include GNC, Tree of Life, United Natural Foods, Inc.
("United Naturals"), Nature's Best, Inc. and other distributors that supply
retailers of vitamins, herbs and other nutritional supplements. Management
believes that it sells its products to every major nutritional supplement
distributor servicing health food stores and is generally the largest
independent supplier of nutritional supplements to such distributors. The
Company is also currently expanding distribution into domestic military
exchanges.
    
 
     Several of the Company's distributors, such as GNC, Tree of Life and United
Naturals, are national in scope, but most are regional in nature and operate one
or more localized distribution centers. Generally, the Company enters into
nonexclusive area rights agreements with its domestic distributors, who are also
responsible for new account development. Retailers typically place orders with
and are supplied directly by the Company's distributors. In the past ten years,
the Company has not lost a major distributor customer other than through
consolidation with an existing customer of the Company. The breadth and depth of
the products manufactured and the ability to manufacture with minimal throughput
times enables the Company to maintain extremely high order fill rates, which
management believes are among the highest in the industry, with its customer
base.
 
     Tree of Life and GNC accounted for approximately 19% and 23%, respectively,
of the Company's net sales in 1997. No other single customer accounted for more
than 10% of the Company's net sales in 1997. The largest retail organization
which sells the Company's products is GNC, with approximately 3,400 stores.
 
     The Company believes that substantial long-term growth opportunities exist
within the mass market distribution channel. The Company's major customers among
mass market retailers include Wal-Mart, Albertson's, Inc., American Stores,
Inc., Duane Reade Inc., Rite Aid Corporation and Safeway, Inc. Management is
continuing its efforts to expand its presence in mass market retail outlets and
recently hired a President of Mass Market Sales to oversee the Company's efforts
in this distribution channel.
 
     Changes International currently markets and distributes 10 products through
a network of over 60,000 independent distributors in the United States and
Canada. The distributor network markets Changes International's products
directly to consumers.
 
   
     Approximately 5.1%, or $10.9 million, of the Company's net sales in 1997
were derived from international sales originating from overseas distributor
organizations. The Company presently has distribution agreements covering
fourteen western European countries, including Great Britain, France, Belgium,
the Netherlands and the Scandinavian countries; six eastern European countries,
including Russia; nine Latin American countries, including Mexico, Brazil and
Argentina; eight Middle Eastern countries, including Israel and Saudi Arabia;
and several other countries in the Far East and the Caribbean. The Company has
also initiated new programs to qualify distributors in Italy and China.
    
 
MARKETING
 
     The Company's marketing strategy, which centers around an extensive
advertising and promotion program, has been a critical component of the
Company's growth, strong brand name recognition and leading position within the
nutritional supplement industry.
 
                                       35
<PAGE>   37
 
     The Company's marketing and advertising expenditures were approximately
$15.9 million in 1997, $12.7 million in 1996 and $11.1 million in 1995. The
Company has budgeted $20.5 million for marketing and advertising expenditures in
fiscal 1998, a 29.2% increase over fiscal 1997. Approximately 45.5% of the
Company's 1998 advertising budget is slated for network and cable television
programming. Of the Company's \$13.0 million in 1997 advertising expenditures,
approximately $4.8 million, or 37.3%, was spent on print advertising,
approximately $5.1 million, or 38.8%, was spent on television and radio
advertising and approximately $3.1 million, or 23.9%, was spent on production of
advertising materials. As the Company's customers align themselves with fewer
vendors of brand name products, the Company believes that its strong commitment
to advertising and promotion will continue to constitute a significant
competitive advantage. The Company's advertising strategy stresses brand
awareness of the Company's various product categories in order to generate
purchases by customers and also communicates the points-of-difference between
the Company's products and those of its competitors.
 
     Print advertisements continue to be an integral part of the Company's
advertising efforts. The Company regularly advertises in consumer magazines such
as Better Nutrition, Delicious, Vegetarian Times, Let's Live, Natural Health,
Nutrition Science Journal, New Age Journal, Muscle & Fitness and Flex. The
Company also plans to expand its print advertising into more widely circulated
publications such as GQ, Men's Health & Fitness and Reader's Digest.
 
     Other marketing and advertising programs conducted by the Company include
participation in or sponsorship of sporting events such as running competitions,
including the Boston Marathon and the Los Angeles Marathon, and bodybuilding
shows, including Team Universe, Fitness America and Natural Eastern Classic, and
sponsorship of health-oriented television and radio programs. In addition, the
Company promotes its products at major industry trade shows and through in-store
point of sale materials. The Company also engages athletic personalities as well
as scientists to communicate on the Company's behalf with the trade and the
public and to promote the Company's products.
 
     The Company extended its marketing efforts in 1997 to include a new site on
the World Wide Web at http://www.twinlab.com, which provides an overview of the
Company in addition to a product catalog. The site also provides a list of
retailers carrying the Company's products and is linked to other sites,
including those of the Company's Nature's Herbs division
(http://www.herbalvillage.com) and the publishing division
(http://www.musculardevelopment.com). Changes International's web site can be
reached at http://www.changesinternational.com. Information contained in any of
the Company's Web sites shall not be deemed to be a part of or incorporated by
reference into this Prospectus.
 
CUSTOMER SALES SUPPORT
 
     The Company's established customer relationships are based upon the
Company's long-standing commitment to a high level of customer service. The
Company's sales force currently consists of 32 dedicated sales professionals
whose primary functions are to gain better placement and additional shelf space
for TWINLAB, Nature's Herbs and Alvita products and to stay abreast of customer
needs. These sales representatives are assigned to specific territories covering
the entire continental United States and Alaska. These personnel work with
direct accounts, distributors and individual retailers to enhance knowledge of
the Company's products and to maximize exposure for TWINLAB, Nature's Herbs and
Alvita products. An additional sales and marketing staff supports Nature's Herbs
products and the servicing of customer needs. The Company is presently expanding
its administrative and sales infrastructure to service its increased sales in
the mass market channel. The Company also designs and supplies a broad range of
marketing literature, including brochures, pamphlets and in-store display
materials to help educate retailers and consumers as to the benefits of the
Company's products.
 
     The Company operates an in-house customer service department to respond to
inquiries requesting information concerning product applications, background
data, ingredient compositions and the efficacy of products. The department is
currently staffed by three nutrition experts.
 
     Changes International provides its independent distributors with a broad
range of informational materials, including product brochures, sales tools,
business and information forms, audio materials and initial distributor
                                       36
<PAGE>   38
 
startup kits. Changes International maintains a 24-hour toll-free phone line for
receiving distributors' orders and a separate customer service line to answer
product questions.
 
MANUFACTURING AND PRODUCT QUALITY
 
     Virtually all of the Company's TWINLAB products are manufactured at the
Company's 72,000 square foot manufacturing facility located in Ronkonkoma, New
York (the "New York Facility"). Herbal supplements and phytonutrients are
manufactured at the Company's 57,000 square foot FDA registered Utah Facility
and at the New York Facility. Herb teas are currently packaged by an independent
contractor and are warehoused at the Utah Facility. Changes International's
product line is currently manufactured and packaged by an independent contractor
pursuant to the Company's specifications and warehoused in Destin, Florida. The
Company's two modern manufacturing facilities provide the Company with the
capability to promptly meet customers' sales demands and to maintain the highest
level of quality control. The Company is continuously upgrading its facilities
and enhancing its manufacturing capabilities through new equipment purchases and
technological improvements. Management believes that the Company's manufacturing
facilities are among the most advanced in the nutritional supplement industry.
In 1996, the Company completed an addition of approximately 8,500 square feet to
the Utah Facility to provide additional plant capacity for the operations of the
Nature's Herbs and Alvita divisions of the Company. In March 1998, the Company
commenced construction of an 85,000 square foot addition to its Utah Facility
which will provide additional capacity for the production, warehouse and
distribution operations, as well as additional office space for the Nature's
Herbs and Alvita divisions. The cost of the project, including land,
construction and equipment, will total approximately $13.0 million. It will be
financed through a nine-month construction loan that will be converted to a
fifteen year mortgage. Management believes that the Company's New York and Utah
Facilities will be sufficient to enable the Company to meet sales demand for the
foreseeable future. If additional space is required, management believes that it
will have the option to lease or purchase additional space or to construct an
additional facility.
 
     The Company's modern manufacturing operations feature pharmaceutical
quality blending, filling and packaging capabilities, which enable the Company
to offer quality and consistency in formulation and dosage forms. The Company
operates flexible manufacturing lines which enable it to efficiently and
effectively shift output among various products as dictated by customer demand.
The Company is capable of producing over 40 million capsules and tablets, over
100,000 pounds of blended powder and up to 2,500 gallons of liquid preparations
per day. The Company has ten high-speed capsule and tablet packaging lines, two
high-speed liquid filling lines and two powder filling lines, which are capable
of operating simultaneously, at its New York and Utah Facilities. The Company
manufactures the powders used in its Ultra Fuel, Hydra Fuel and Nitro Fuel
single-serving sports drink products and utilizes a contract bottler for the
hydration and bottling of these products. The Company operates on a 24-hour work
day that includes two production shifts and a third shift primarily for
cleaning, maintenance and equipment set-up.
 
     The Company sources its raw material needs from over 200 different
suppliers, including some of the largest pharmaceutical and chemical companies
in the world. The Company's raw materials and packaging supplies are readily
available from multiple suppliers, and the Company is not dependent on any
single supplier for its needs. No single supplier accounted for more than 10% of
the Company's total purchases in 1997.
 
     The Company's quality standards are a critical factor in consumer purchase
decisions, and the Company believes it has established a competitive advantage
based on the quality of its products. All capsule and tablet products
manufactured by the Company are visually inspected before being packaged.
Moreover, each of the Company's products undergoes comprehensive quality control
testing procedures from the receipt of raw materials to the release of the
packaged product. The Company utilizes real-time computerized monitoring of its
manufacturing processes to ensure proper product weights and measures. In
addition, the Company maintains two in-house laboratories with state-of-the-art
testing and analysis equipment where the Company performs most of its testing,
including stability tests, active component characterization utilizing
thin-layer and high-pressure liquid chromatography, and UV visible and infrared
spectrometry. The Company contracts with independent laboratories to perform the
balance of its testing requirements. A team of 63 full-time
                                       37
<PAGE>   39
 
quality assurance professionals regularly conducts a wide variety of visual and
scientific tests on all manufactured products, and samples of raw materials and
finished products are retained for quality control purposes for up to five
years.
 
     The Company has a strong commitment to maintaining the quality of the
environment. All of the Company's plastic and corrugated cardboard containers
are recyclable and, wherever possible, the Company uses recyclable glass. The
Company was also one of the first companies in the industry to use biodegradable
starch pellets for packing materials. In addition, the Company has removed most
solvents from its production processes (using natural, environmentally-safe
alternatives) and helped develop a special glue, for manufacturing purposes,
that contains virtually no harmful hydrocarbons. The Company believes it is in
material compliance with all applicable environmental regulations.
 
COMPETITION
 
     Vitamins and nutritional supplements are sold primarily through several
channels of distribution: health food stores, mass market retailers (drug store
chains, supermarkets and other mass merchandisers), and direct sales channels
(including network marketing and catalog distribution).
 
     The Company's principal competitors in the health food store market include
Nutraceutical International Corporation, Weider Nutrition International, Inc.,
Nature's Way Products, Inc., Solgar Vitamin and Herb Company, Inc. and Nature's
Plus Inc. Private label products of the Company's customers also provide
competition to the Company's products. For example, a substantial portion of
GNC's vitamin and mineral supplement offerings are products offered under GNC's
own private label.
 
     The Company believes that the growing number of health food retailers are
increasingly likely to align themselves with those companies which offer a wide
variety of high quality products, have a loyal customer base, support their
brands with strong marketing and advertising programs and provide consistently
high levels of customer service. The Company believes that it competes favorably
with other nutritional supplement companies because of its comprehensive line of
products, premium brand names, commitment to quality, ability to rapidly
introduce innovative products, competitive pricing, high customer-order fill
rate, strong and effective sales force and distribution network, and
sophisticated advertising and promotional support. The wide variety and
diversity of the forms, potencies and categories of the Company's products are
important points of differentiation between the Company and many of its
competitors.
 
     In the mass market retail channel of distribution, the Company competes
with major private label and broadline brand manufacturers, including Leiner
Health Products Inc., Pharmavite Corp., Rexall Sundown, Inc. and NBTY, Inc.,
certain of which are larger and have access to greater resources than the
Company. The Company competes on the basis of customer service, product quality,
pricing and marketing support. The Company believes that it competes favorably
with other companies because of its (i) sales and marketing strategies, (ii)
customer service (including speed of delivery) and (iii) reputation as being a
supplier of quality products.
 
     Many of the Company's competitors in markets other than the health food
store market, including the major pharmaceutical companies, have substantially
greater financial and other resources than the Company.
 
     Although Changes International competes with other health and nutritional
food companies, the Company believes Changes International's primary competition
stems from other network marketing companies. Changes International competes in
the recruitment of independent distributors with other network marketing
organizations whose product lines may or may not compete with its products.
 
REGULATORY MATTERS
 
  Government Regulation
 
     The manufacturing, processing, formulating, packaging, labeling and
advertising of the Company's products are subject to regulation by one or more
federal agencies, including the FDA, the FTC, the Consumer Product Safety
Commission, the United States Department of Agriculture and the Environmental
 
                                       38
<PAGE>   40
 
Protection Agency. These activities are also regulated by various agencies of
the states, localities and foreign countries to which the Company's products are
distributed and in which the Company's products are sold. The FDA, in
particular, regulates the formulation, manufacture and labeling of vitamin and
other nutritional supplements.
 
     On October 25, 1994, the President signed into law the DSHEA. This new law
revises the provisions of the FFDC Act concerning the composition and labeling
of dietary supplements and, in the judgment of the Company, is favorable to the
dietary supplement industry. The legislation creates a new statutory class of
"dietary supplements." This new class includes vitamins, minerals, herbs, amino
acids and other dietary substances for human use to supplement the diet, and the
legislation grandfathers, with certain limitations, dietary ingredients on the
market before October 15, 1994. A dietary supplement which contains a new
dietary ingredient, one not on the market before October 15, 1994, will require
evidence of a history of use or other evidence of safety establishing that it
will reasonably be expected to be safe. The substantial majority of the products
marketed by the Company are classified as dietary supplements under the FFDC
Act.
 
     Both foods and dietary supplements are subject to the NLEA which prohibits
the use of any health claim for foods, including dietary supplements, unless the
health claim is supported by significant scientific agreement and is either
pre-approved by the FDA or the subject of substantial government scientific
publications and a notification to the FDA. To date, the FDA has approved the
use of only limited health claims for dietary supplements. However, among other
things, the DSHEA amends, for dietary supplements, the NLEA by providing that
"statements of nutritional support" may be used in labeling for dietary
supplements without FDA pre-approval if certain requirements, including
prominent disclosure on the label of the lack of FDA review of the relevant
statement, possession by the marketer of substantiating evidence for the
statement and post-use notification to the FDA, are met. Such statements may
describe how particular nutritional supplements affect the structure, function
or general well-being of the body (e.g. "promotes your cardiovascular health").
 
     The FDA issued final dietary supplement labeling regulations in 1997 that
require the Company to revise most of its product labels by 1999. The
regulations also currently require the Company to submit notification to the FDA
of all "statements of nutritional support," a process that the Company has not
fully completed.
 
     Advertising and label claims for dietary supplements and conventional foods
have been regulated by state and federal authorities under a number of disparate
regulatory schemes. There can be no assurance that a state will not interpret
claims presumptively valid under federal law as illegal under that state's
regulations, or that future FDA regulations or FTC decisions will not restrict
the permissible scope of such claims.
 
     Governmental regulations in foreign countries where the Company plans to
commence or expand sales may prevent or delay entry into the market or prevent
or delay the introduction, or require the reformulation, of certain of the
Company's products. Compliance with such foreign governmental regulations is
generally the responsibility of the Company's distributors for those countries.
These distributors are independent contractors over whom the Company has limited
control.
 
     As a result of the Company's efforts to comply with applicable statutes and
regulations, the Company has from time to time reformulated, eliminated or
relabeled certain of its products and revised certain provisions of its sales
and marketing program. The Company cannot predict the nature of any future laws,
regulations, interpretations or applications, nor can it determine what effect
additional governmental regulations or administrative orders, when and if
promulgated, would have on its business in the future. They could, however,
require the reformulation of certain products to meet new standards, the recall
or discontinuance of certain products not capable of reformulation, additional
recordkeeping, expanded documentation of the properties of certain products,
expanded or different labeling, and/or scientific substantiation. Any or all of
such requirements could have a material adverse effect on the Company's results
of operations and financial condition.
 
     The Company's Utah Facility is registered with the FDA as a manufacturer of
OTC drugs and is subject to periodic inspection by the FDA.
 
                                       39
<PAGE>   41
 
     Compliance with the provisions of national, state and local environmental
laws and regulations has not had a material adverse effect upon the capital
expenditures, earnings, financial position, liquidity or competitive position of
the Company. See also "Business -- Legal Matters."
 
  Ma Huang
 
   
     Approximately 15 of the Company's products include an herb known as "Ma
Huang," which contains naturally-occurring ephedrine. Certain of such products
also contain caffeine or other central nervous system stimulants. Such products
accounted for approximately 13.0% of the Company's net sales in 1997. The
Company's products which contain Ma Huang are generally marketed for
bodybuilding, weight loss, sports nutrition and other purposes, including
increased endurance and energy, generally in conjunction with diet or exercise,
and as natural alternatives to over-the-counter medications.
    
 
   
     Ma Huang has been the subject of certain adverse publicity in the United
States and other countries relating to alleged harmful or adverse effects. The
FDA has proposed regulations relating to the sale of dietary supplements
containing Ma Huang which, if promulgated in final form, would require the
Company to substantially reformulate and relabel almost all of its Ma Huang
products and would limit potency, require warnings, prohibit certain combination
products and would preclude the Company from making bodybuilding and weight loss
claims for such products. Comments from industry participants and inquiries from
Committees of the United States Congress have been filed with the FDA
challenging the scientific and legal basis for the proposed regulations. The
Company is not able to predict whether the FDA's proposed regulations will
become final. There can be no assurance as to the effect that any resulting
reformulation, relabeling or change in the marketing of the Company's products
would have on the sales of such products. In 1996, the Company introduced a line
of Ma Huang-free products as alternatives to certain of its bodybuilding and
sports nutrition products which currently contain Ma Huang. The Company's net
sales of Ma Huang-free products were $1.9 million for fiscal 1997. There can be
no assurance that sales of such alternative products would offset any decrease
in sales attributable to any reformulation or relabeling of the Company's Ma
Huang products.
    
 
     A number of state and local governments have proposed or passed legislation
prohibiting or regulating the sale of Ma Huang products. The Company's products
containing Ma Huang may become subject to further federal, state, local or
foreign laws or regulations, which could also require the Company to reformulate
its products with reduced ephedrine levels or with a substitute for Ma Huang
and/or relabel its products with different warnings or revised directions for
use. There can be no assurance that the loss of sales of the Company's Ma Huang
products would not have a material adverse effect on the Company. See
"Business -- Legal Matters."
 
EMPLOYEES
 
     At December 31, 1997, the Company employed 634 persons, of which 134 were
involved in executive, sales and administrative activities. The balance of the
Company's employees were engaged in production, packaging and shipping
activities. Changes International also subcontracts an additional 67 persons
from an independent personnel agency. None of the Company's employees are
covered by a collective bargaining agreement, and management considers relations
with its employees to be good.
 
PROPERTIES
 
     The Company owns a modern vitamin, mineral and nutritional supplement
manufacturing facility in Ronkonkoma, New York. The 72,000 square foot New York
Facility also houses the Company's executive offices. The Company recently
signed a lease for approximately 21,000 square feet of space in a modern office
building in Hauppauge, New York and expects to move all of its corporate and
most of its administrative offices to this location in the second quarter of
fiscal 1998. The Company leases 26,300 square feet of warehouse space in
Ronkonkoma, 60,000 square feet of warehousing space in Hauppauge, and 5,000
square feet of office space in Ronkonkoma. In addition, the Company owns the
modern FDA-registered 57,000 square foot Utah Facility. The Utah Facility, which
was initially constructed in 1993, houses office,
 
                                       40

manufacturing and warehousing facilities for the operations of the Nature's
Herbs division and office and warehousing facilities for the operations of the
Alvita division. The Company also leases 21,500 square feet of warehouse and
office space in Destin, Florida for Changes International.
 
     The Company believes that its facilities and equipment generally are well
maintained and in good operating condition. In 1996, the Company completed an
addition of approximately 8,500 square feet to the Utah Facility at a cost of
approximately $700,000 to provide additional plant capacity for the operations
of the Nature's Herbs and Alvita divisions of the Company. In March 1998, the
Company commenced construction of an 85,000 square foot addition to its Utah
Facility which will provide additional capacity for the production, warehouse
and distribution operations, as well as additional office space for the Nature's
Herbs and Alvita divisions. The cost of the project, including land,
construction and equipment, will total approximately $13.0 million,
approximately $8.0 million of which will be financed through a nine-month
construction loan that will be converted to a fifteen year mortgage. Management
believes that the Company's New York and Utah Facilities will be sufficient to
enable the Company to meet sales demand for the foreseeable future. If
additional space is required, management believes that it will have the option
to lease or purchase additional space or to construct an additional facility.
 
TRADEMARKS
 
     The Company owns trademarks registered with the United States Patent and
Trademark Office and/or similar regulatory authorities in many other countries
for its TWINLAB, Nature's Herbs, Alvita, Changes and Fuel family of trademarks,
and has rights to use other names material to its business. In addition, the
Company has obtained trademarks for various of its products and has
approximately 289 trademark registrations with the United States Patent and
Trademark Office for TWINLAB, Nature's Herbs, Alvita and Changes brands.
Federally registered trademarks have perpetual life, provided they are renewed
on a timely basis and used properly as trademarks, subject to the rights of
third parties to seek cancellation of the marks. The Company regards its
trademarks and other proprietary rights as valuable assets and believes that
they have significant value in the marketing of its products. The Company
vigorously protects its trademarks against infringement.
 
LEGAL MATTERS
 
     The Company, like other retailers, distributors and manufacturers of
products that are ingested, faces an inherent risk of exposure to product
liability claims in the event that, among other things, the use of its products
results in injury. The Company may be subjected to various product liability
claims, including, among others, that its products contain contaminants or
include inadequate instructions as to use or inadequate warnings concerning side
effects and interactions with other substances. While such claims to date have
not been material to the Company and the Company maintains product liability
insurance, there can be no assurance that product liability claims and the
resulting adverse publicity will not have a material adverse effect on the
Company. The Company carries insurance in the types and amounts that management
considers reasonably adequate to cover the risks associated with its business.
There can be no assurance that such insurance will continue to be available at a
reasonable cost, or if available will be adequate to cover liabilities.
 
     The Company has been a defendant in court actions seeking damages for
alleged personal injuries resulting from products containing allegedly
contaminated added manufactured L-Tryptophan. To date, 132 of the 133
L-Tryptophan actions brought against the Company (the "L-Tryptophan Actions")
have been dismissed or settled at no cost to the Company pursuant to an
indemnification agreement (the "Indemnification Agreement") between the Company
and a U.S. subsidiary of the Japanese manufacturer of the allegedly contaminated
ingredient. The Company believes that few new lawsuits are likely to be brought
in view of applicable statutes of limitation and, in light of the
Indemnification Agreement and the resolution of virtually all of the
L-Tryptophan Actions at no cost to the Company, that the prospect of the
remaining L-Tryptophan Actions and any possible future actions having a material
adverse effect on the Company's results of operations or financial condition is
remote. The Company ceased marketing products containing added manufactured
L-Tryptophan in 1990.

     The Company has been named as a defendant in three currently pending
lawsuits alleging that its Ma Huang containing products caused injuries and/or
damages, including a proceeding seeking class action certification. The Company
intends to vigorously defend these lawsuits. The Company believes that such
claims, if successful, would not have a material adverse effect on the financial
condition or results of operations of the Company. There can be no assurance
that the Company will not be subject to further private civil actions with
respect to its Ma Huang products.
 
     The State of California and the NRDC filed lawsuits against the Company and
a large number of manufacturers of dietary supplements containing calcium,
claiming that naturally-occurring lead levels in these supplements exceed
acceptable levels under California law ("Proposition 65"). The NRDC settled its
suit with the manufacturers, including the Company. The State of California
settled the first of two phases of its lawsuit with the Company and the other
manufacturers and is engaged in settlement discussions with respect to the
remainder of the case. The Company also received notice of a possible State of
California legal claim relating to alleged toxic impurities in fish oil
products. No action has been filed. There can be no assurance that the Company
will not be the subject of future Proposition 65 claims asserted by the State of
California or private parties.
 
     The Company is presently engaged in various other legal actions which arise
in the ordinary course of business. Although ultimate liability cannot be
determined at the present time, the Company believes that the amount of any such
liability, if any, from these other actions, after taking into consideration the
Company's insurance coverage, will not have a material adverse effect on its
results of operations or financial condition.

 (c) The shares shown as beneficially owned by Messrs. Danhakl and Sokoloff and
     Ms. Holden Dunbar represent 8,880,000 shares owned of record by GEI. GEI is
     a Delaware limited partnership managed by LGP, which is an affiliate of the
     general partner of GEI. Each of Leonard I. Green, Jonathan D. Sokoloff,
     John G. Danhakl, Peter J. Nolan, Gregory J. Annick and Jennifer Holden
     Dunbar, either directly (whether through ownership interest or position) or
     through one or more intermediaries, may be deemed to control LGP and such
     general partner. LGP and such general partner may be deemed to control the
     voting and disposition of the shares of Common Stock of Twinlab owned by
     GEI. As such, Messrs. Sokoloff and Danhakl and Ms. Holden Dunbar may be
     deemed to have shared voting and investment power with respect to all
     shares held by GEI. However, such individuals disclaim beneficial ownership
     of the securities held by GEI except to the extent of their respective
     pecuniary interests therein.

TERMS OF THE STOCKHOLDERS AGREEMENT
 
     Upon consummation of the Acquisition, GEI, the Senior Executive Officers
and Twinlab entered into a Stockholders Agreement (the "Stockholders Agreement")
in respect of their holdings of shares of Common Stock of Twinlab. Pursuant to
the Stockholders Agreement, each of GEI and the Senior Executive Officers was
granted certain demand registration rights. The Stockholders Agreement also
contains certain "piggyback" registration rights arising in the event that
Twinlab registers its securities under the Securities Act. The Stockholders
Agreement terminates on the tenth anniversary of the date thereof.
 
     Shares of Common Stock and Senior Preferred Stock of Twinlab were issued to
various institutional investors (the "Institutional Investors") pursuant to a
Stock Subscription Agreement among each such investor and Twinlab. Upon
consummation of the Acquisition, GEI, the Senior Executive Officers, the
Institutional Investors and Twinlab entered into a secondary stockholders
agreement (the "Secondary Stockholders Agreement") in respect of their holdings
of shares of capital stock of Twinlab. Commencing on the fifth anniversary of
the Secondary Stockholders Agreement, the Institutional Investors will be
entitled to exercise one demand registration right with respect to their shares
of Common Stock of Twinlab. Finally, the Institutional Investors will have
certain "piggyback" registration rights on other registrations of equity
securities of the Company. The Secondary Stockholders Agreement terminates on
the tenth anniversary of the date thereof.
 
                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
THE AMENDED AND RESTATED REVOLVING CREDIT FACILITY
 
     In November 1996, Twinlab and Twin entered into the Revolving Credit
Facility agented by Chase and co-agented by Bank of New York. The Revolving
Credit Facility provides for a revolving credit facility for Twin of $50.0
million expiring on May 7, 2002. The Revolving Credit Facility bears interest at
an annual rate, at the option of Twin equal to the ABR plus the Applicable
Margin ("ABR Loans") or the Eurodollar Rate plus Applicable Margin ("Eurodollar
Loans"). With respect to the Revolving Credit Facility, "Applicable Margin"
means (a) 0%, in the case of ABR Loans and (b) 1.25%, in the case of Eurodollar
Loans. Interest rates on the Revolving Credit Facility are subject to increase
or reduction based on Twin's meeting certain financial tests. Outstanding
borrowings under the Revolving Credit Facility currently bear interest at a rate
of 6.875% per annum.
 
     The proceeds of the Revolving Credit Facility are available for the working
capital requirements of Twin and its subsidiaries and for general corporate
purposes, including up to $35.0 million to fund permitted acquisitions (as
defined), subject in each case to certain conditions and reductions set forth in
the Revolving Credit Facility. As of December 31, 1997, approximately $36.3
million of borrowings were available under the Revolving Credit Facility for
working capital requirements and general corporate purposes of which
approximately $21.3 million was available for acquisitions. See "Use of
Proceeds." A portion of the Revolving Credit Facility not to exceed $15.0
million is available for the issuance of letters of credit which generally will
have an initial term of one year or less.
 
     The Revolving Credit Facility is secured by first priority security
interests in all of the tangible and intangible assets of the Company. In
addition, the loans under the Revolving Credit Facility are guaranteed by
Twinlab, ARP, Changes International and certain of Twin's future subsidiaries.
Additionally, Twin is required to apply various percentages of the net proceeds
of (i) certain issuances or sales of equity by Twinlab (provided that in the
case of a public offering by Twinlab of its capital stock, the net proceeds
thereof may be used, at the discretion of Twinlab and Twin, including without
limitation, to redeem or retire the Notes and/or to reduce the Revolving Credit
Facility), (ii) the incurrence of certain indebtedness by Twinlab or its direct
or indirect subsidiaries, or (iii) any disposition of any material assets (other
than inventory in the ordinary course of business), to the repayment of the
Revolving Credit Facility.
 
                                       48
<PAGE>   50
 
     The Revolving Credit Facility contains certain financial and operating
covenants, including a maximum leverage ratio and a minimum interest coverage
ratio. In addition, Twin and its subsidiaries are limited in the amount of
annual capital expenditures and capital lease obligations they may incur.
 
     The operating covenants of the Revolving Credit Facility include
limitations on the ability of the Company to (i) incur additional indebtedness,
other than certain permitted indebtedness, (ii) permit additional liens or
encumbrances, other than certain permitted liens, (iii) make any investment in
other persons, other than certain permitted investments; (iv) become obligated
with respect to contingent obligations, other than certain permitted contingent
obligations, and (v) make restricted junior payments (including dividends on its
common stock). The operating covenants also include restrictions on certain
specified fundamental changes, such as mergers and asset sales, transactions
with shareholders and affiliates, and business outside the ordinary course as
currently conducted, amendments or waivers of certain specified agreements, and
the issuance of preferred stock, guarantees or other credit enhancements.
 
DESCRIPTION OF NOTES
 
     The 10 1/4% Senior Subordinated Notes due 2006 (the "Notes") were issued in
a transaction (the "Notes Offering") pursuant to which Twin issued an aggregate
of $100,000,000 principal amount of the Notes to Donaldson, Lufkin & Jenrette
Securities Corporation ("DLJ") and Chase Securities Inc. (together with DLJ, the
"Initial Notes Purchasers") on May 7, 1996 (the "Note Offering Closing Date").
The Initial Notes Purchasers subsequently resold the Notes in reliance on Rule
144A and certain other exemptions under the Securities Act. The Company and the
Initial Notes Purchasers also entered into a Registration Rights Agreement,
pursuant to which the Company granted certain registration rights for the
benefit of the holders of the Notes. On October 28, 1996, the Company
consummated a fully-subscribed registered exchange offer under the Securities
Act for the Notes (the "Exchange Offer") to satisfy certain of the Company's
obligations under the Registration Rights Agreement with respect to the Notes.
The form and terms of the notes issued under the Exchange Offer are identical in
all material respects to the form and terms of the Notes.
 
     The Notes were issued under an indenture, dated as of the Note Offering
Closing Date (the "Indenture"), among Twinlab, Twin, ARP and Fleet National Bank
as trustee. The Indenture was supplemented as of December 1, 1997 to add Changes
International as a Guarantor (as hereinafter defined) thereunder. The Notes are
not redeemable, in whole or in part, prior to May 15, 2001. Thereafter, the
Notes are redeemable at the redemption prices set forth in the Indenture, plus
interest accrued thereon to the redemption date. Notwithstanding the foregoing,
at any time on or before May 15, 1999, Twin may redeem up to 35% of the original
aggregate principal amount of the Notes, in whole or in part, with the net
proceeds of one or more Equity Offerings (as defined therein) at a redemption
price equal to 109 1/2% of the principal amount thereof, plus accrued and unpaid
interest, if any, to the date of redemption. Upon the occurrence of a Change of
Control (as defined therein), Twin will be required to make an offer to
repurchase all outstanding Notes at 101% of the aggregate principal amount
thereof, plus accrued and unpaid interest, if any, to the date of repurchase.
 
     The Notes are general unsecured obligations of Twin subordinated in right
of payment to all existing and future Senior Debt (as defined therein) of Twin,
including borrowings under the Revolving Credit Facility. The payment of the
principal, premium, if any, and interest on the Notes are guaranteed (the
"Guarantees") by Twinlab, ARP and Changes International (the "Guarantors"). The
Guarantees are subordinated in right of payment to all existing and future
Senior Debt of the Guarantors. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources." The Indenture permits the Company to incur additional indebtedness,
including additional Senior Debt. The Indenture contains certain covenants with
respect to Twin and the Subsidiary Guarantors (as defined therein) that limit
the ability of Twin and the Subsidiary Guarantors to, among other things, (i)
incur additional Indebtedness (as defined therein) and issue certain preferred
stock, (ii) pay dividends or make other distributions, (iii) layer Indebtedness,
(iv) create certain liens, (v) sell certain assets, (vi) enter into certain
transactions with affiliates, or (vii) enter into certain mergers or
consolidations involving Twin.

                          DESCRIPTION OF CAPITAL STOCK
 
     The Company is authorized by its Certificate of Incorporation to issue
75,000,000 shares of Common Stock, $1.00 par value per share, of which
31,321,500 shares will be outstanding upon completion of the Offerings, and
2,000,000 shares of preferred stock, $.01 par value per share, none of which
shares will be outstanding upon consummation of the Offerings.
 
     The following summary description of the capital stock of Twinlab is
qualified in its entirety by reference to the Certificate of Incorporation and
the By-laws, which are incorporated by reference herein.
 
COMMON STOCK
 
     Holders of shares of Common Stock vote as a single class on all matters
submitted to a vote of the stockholders, including the election of directors,
with each share of Common Stock entitled to one vote. There is no cumulative
voting with respect to the election of directors, with the result that holders
of more than 50% of the shares voting for the election of directors can elect
all of the directors. Upon completion of the Offerings, GEI will own 16.8% and
the Senior Executive Officers of the Company will own 26.6% of the Common Stock
of Twinlab.
 
     Holders of Common Stock on the applicable record date are entitled to share
ratably in such dividends, if any, as may be declared from time to time by the
Board of Directors out of funds legally available therefor, subject to the
rights of the holders of any series of preferred stock. See "Dividend Policy."
Upon the liquidation, dissolution or winding up of the Company, each holder of
Common Stock will be entitled to share ratably in any distribution of the
Company's assets after the payment of all debts and other liabilities, subject
to any superior rights of the holders of any outstanding shares of preferred
stock.
 
     Holders of the shares of Common Stock have no preemptive or other
subscription rights and there are no conversion rights or redemption or sinking
fund provisions with respect to such shares. All of the outstanding shares of
Common Stock are, and the shares of Common Stock offered hereby will be when
issued, fully paid and non-assessable.
 
     Special meetings of stockholders may be called by the Company's Board of
Directors, the Chairman of the Board of Directors, the President or the holders
of twenty-five (25%) of the then outstanding Common Stock.
 
     Stockholders of the Company are required to provide advance notice of
nominations of directors to be made at, and of business proposed to be brought
before, a meeting of stockholders. The failure to deliver proper notice within
the period specified in the Company's By-laws will result in the denial to the
stockholder of the right to make such nominations or propose such action at the
meeting.
 
PREFERRED STOCK
 
     The Company's Board of Directors has authority (without action by the
stockholders) to issue authorized and unissued shares of preferred stock in one
or more series, to designate the number of shares constituting any series, and
to fix, by resolution, the voting powers, designations, preferences and
relative, optional or other special rights thereof, including liquidation
preferences and the dividend, conversion and redemption rights of each such
series. Under certain circumstances, the Company could issue the preferred stock
as a method of discouraging, delaying or preventing a change of control of the
Company.
 
CERTAIN PROVISIONS OF THE DELAWARE GENERAL CORPORATION LAW ("DGCL")
 
     Section 228 of the DGCL allows any action which is required to be or may be
taken at a special or annual meeting of the stockholders of a corporation to be
taken without a meeting with the written consent of holders of outstanding stock
having not less than the minimum number of votes that would be necessary to
authorize or take such action at a meeting at which all shares entitled to vote
thereon were present and voted, provided that the certificate of incorporation
of such corporation does not contain a provision to the contrary. The
Certificate of Incorporation contains no such provision, and therefore, pursuant
to Section 228 and the By-
 
                                       50
<PAGE>   52
 
laws, stockholders holding a majority of the voting power of the Common Stock
will be able to effect most corporate matters requiring stockholder approval by
written consent, without the need for a duly-noticed and duly-held meeting of
stockholders. See "Risk Factors -- Control by Principal Stockholders."
 
TRANSFER AGENT AND REGISTRAR
 
     The Transfer Agent and Registrar for the Common Stock is American
Securities Transfer & Trust, Inc. American Securities Transfer & Trust, Inc. is
located at 1825 Lawrence Street, Suite 444, Denver, Colorado 80202-1817, and its
telephone number is (303) 298-5370.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of the Offerings, Twinlab will have 31,321,500 shares of
Common Stock outstanding, of which 16,832,750 shares will be freely tradeable
without restriction or further registration under the Securities Act, except
that any shares held by "affiliates" of the Company, as that term is defined
under the Securities Act ("Affiliates"), may generally only be sold in
compliance with the limitations of Rule 144 described below.
 
     The remaining 14,488,750 shares of Common Stock (the "Restricted Shares")
constitute restricted securities under Rule 144 and were issued by the Company
in private transactions in reliance upon one or more exemptions under the
Securities Act. Such restricted securities may be resold in a public
distribution only if registered under the Securities Act or pursuant to an
exemption therefrom, including Rule 144. The Senior Executive Officers and the
Selling Stockholders, who collectively are the beneficial owners of an aggregate
of 18,180,420 shares of Common Stock (14,180,420 shares after the consummation
of the Offerings), and the Company have agreed with the Underwriters, subject to
certain exceptions, not to directly or indirectly offer, sell, contract to sell,
grant any option to purchase or otherwise dispose of, without the prior written
consent of Bear Stearns, any Common Stock or any securities convertible into or
exchangeable or exercisable for, or warrants, options or rights to purchase or
acquire Common Stock or in any other manner transfer all or a portion of the
economic consequences associated with the ownership of any Common Stock, or
enter into any agreement to do any of the foregoing, for a period of 90 days
after the date of this Prospectus (the "Lock-Up Period"), except (i) offers to
sell and sales to the Underwriters pursuant to the Offerings and (ii) the
issuance of shares of Common Stock pursuant to employee benefit arrangements of
the Company. Upon the expiration of such 90 day period, such holders will in
general be entitled to dispose of their shares of Common Stock, although the
shares of Common Stock held by affiliates of the Company will continue to be
subject to the restrictions of Rule 144 under the Securities Act.
 
     In general, under Rule 144 of the Securities Act as currently in effect, a
person (or persons whose shares are aggregated) who has beneficially owned
Restricted Shares for at least one year, including a person who may be deemed an
Affiliate of the Company, is entitled to sell within any three-month period a
number of shares of Common Stock that does not exceed the greater of 1% of the
then outstanding shares of Common Stock or the average weekly trading volume in
the Common Stock during the four calendar weeks preceding the date on which
notice of such sale is filed pursuant to Rule 144. Sales under Rule 144 are
subject to certain restrictions relating to manner of sale, notice and the
availability of current public information about the Company. In addition, under
Rule 144(k), a person who is not an Affiliate of the Company at any time 90 days
preceding a sale, and who has beneficially owned shares for at least two years,
would be entitled to sell such shares immediately following the Offerings
without regard to the volume limitations, manner of sale provisions or notice or
other requirements of Rule 144.
 
     Upon completion of the Offerings, 13,570,595 of the Restricted Shares will
be owned by GEI and the Blechman Brothers. The Company has granted the Senior
Executive Officers and the Selling Stockholders certain demand and piggyback
registration rights covering an aggregate of 18,176,250 shares of Common Stock
(14,176,250 shares after the consummation of the Offerings). When and as these
rights are exercised, additional shares will become available for sale upon the
effectiveness of a registration statement filed pursuant to exercise of such
rights. See "Principal and Selling Stockholders -- Terms of the Stockholders
Agreement."
 
     Any sale of substantial amounts of Common Stock in the open market may
adversely affect the market price of the Common Stock offered hereby.

                 CERTAIN UNITED STATES FEDERAL TAX CONSEQUENCES
                          TO NON-UNITED STATES HOLDERS
 
     The following is a general discussion of certain United States federal
income and estate tax consequences of the acquisition, ownership and disposition
of the Common Stock by a "Non-United States Holder." For the purpose of this
summary, a "Non-United States Holder" is any person or entity that is not (a) a
citizen or resident of the United States, (b) a corporation or partnership
created or organized in or under the laws of the United States or of any
political subdivision thereof, (c) an estate that is subject to United States
federal taxation on its income regardless of its source or (d) a trust if a
court within the United States is able to exercise primary supervision over its
administration and one or more United States persons have the authority to
control all substantial decisions of the trust. An individual may be deemed to
be a resident of the United States for federal income tax purposes in several
circumstances, including being present in the United States on at least 31 days
in the calendar year and for an aggregate of 183 days during the three-year
period ending with the current calendar year. For purposes of this
determination, all of the days present in the United States during the current
year, one-third of the days present during the immediately preceding year and
one-sixth of the days present during the second preceding year are taken into
account. Resident aliens are subject to U.S. federal income tax as if they were
U.S. citizens and residents.
 
     This summary does not deal with all aspects of United States federal income
and estate taxation that may be relevant to Non-United States Holders in light
of their personal circumstances and does not address tax consequences under the
laws of any state, municipality, or other taxing jurisdiction or under the laws
of any country other than the United States. Furthermore, this summary is based
on current provisions of the Internal Revenue Code of 1986, as amended (the
"Code"), existing, temporary and proposed regulations promulgated thereunder and
administrative and judicial interpretations, all of which are subject to change,
possibly with retroactive effect. Prospective Non-United States Holders are
urged to consult their tax advisors regarding the United States federal, state,
local and foreign income and other tax consequences of acquiring, owning and
disposing of the Common Stock.
 
DIVIDENDS
 
     The Company does not expect to pay dividends on its Common Stock in the
foreseeable future. See "Dividend Policy." Generally, any dividends paid with
respect to the Common Stock to a Non-United States Holder will be subject to
withholding of United States federal income tax at a 30% tax rate (or such lower
tax rate as may be specified by an applicable income tax treaty). Dividends
received by a Non-United States Holder that are effectively connected with a
United States trade or business conducted by such Non-United States Holder (and
attributable to a U.S. permanent establishment of the Non-United States Holder,
if any income tax treaty applies) are exempt from such withholding tax. However,
such effectively connected dividends, net of certain deductions and credits, are
taxed at the same graduated rates applicable to United States persons.
Effectively connected dividends received by a corporate Non-United States Holder
may be subject to an additional "branch profits tax" at a 30% tax rate (or such
lower rate as may be specified by an applicable income tax treaty). A Non-United
States Holder may claim exemption from withholding under the effectively
connected income exception by filing Form 4224 (Statement Claiming Exemption
from Withholding of Tax on Income Effectively Connected with the Conduct of
Business in the United States) with the Company or its paying agent.
 
     Under current United States Treasury regulations, dividends paid to an
address in a foreign country are presumed to be paid to a resident of such
country for purposes of the withholding discussed above (unless the payor has
knowledge to the contrary) and, under the current interpretation of United
States Treasury regulations, for purposes of determining the applicability of a
tax treaty rate. Recently finalized Treasury regulations generally effective for
payments made after December 31, 1998 (the "Withholding Regulations"), however,
will require Non-United States Holders to file certain new forms to obtain the
benefit of any applicable tax treaty providing for a lower rate of withholding
tax on dividends. Such forms will be required to contain the holder's name,
address and certain other information.
 
                                       52
<PAGE>   54
 
DISPOSITION OF COMMON STOCK
 
     A Non-United States Holder generally will not be subject to United States
federal income tax on any gain recognized upon the sale or other disposition of
Common Stock unless (i) such gain is effectively connected with a United States
trade or business of the Non-United States Holder (and, if the applicable treaty
so provides, is attributable to such holder's office or other fixed place of
business within the United States), (ii) in the case of a Non-United States
Holder who is a non-resident alien individual and holds the Common Stock as a
capital asset, such holder is present in the United States for 183 or more days
in the taxable year of disposition and either (a) has a "tax home" in the United
States for United States federal income tax purposes or (b) has an office or
other fixed place of business in the United States to which the gain is
attributable and no treaty exemption applies, (iii) the Non-United States Holder
is subject to tax pursuant to the provisions of United States federal income tax
laws applicable to certain expatriates or (iv) the Company is or has been a
"United States real property holding corporation" ("USRPHC") at any time within
the shorter of the five-year period preceding such disposition or such
Non-United States Holder's holding period and, provided that the Common Stock
continues to be "regularly traded on an established securities market" for tax
purposes, the Non-United States Holder held, directly or indirectly, at any time
during the five-year period ending on the date of disposition, more than 5% of
the outstanding Common Stock. The Company has determined that it has not been
and is not currently and does not believe that it will become a USRPHC for
federal income tax purposes. If a Non-United States Holder falls under clause
(i) above, the holder will be subject to United States federal income tax on the
same basis as United States persons generally (and, with respect to corporate
Non-United States Holders, may also be subject to the branch profits tax
described above). If an individual Non-United States Holder falls under clause
(ii) above, the holder generally will be subject to a 30% tax on the gain
derived from the sale, which gain may be offset by U.S. capital losses
recognized within the same taxable year of such sale or disposition.
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
     In the event the Company decides, contrary to its present intention, to pay
dividends with respect to its Common Stock, the Company must report to the IRS
the amount of dividends paid, the name and address of the recipient and the
amount, if any, of tax withheld. A similar report will be sent to the Non-United
States Holder. See "Dividend Policy." Pursuant to tax treaties or other
agreements, the IRS may make such reports available to tax authorities in the
recipient's country of residence.
 
     Dividends paid to a Non-United States Holder at an address within the
United States may be subject to backup withholding at a rate of 31% if the
Non-United States Holder fails to establish that it is entitled to an exemption
or to provide a correct taxpayer identification number and other information to
the payor.
 
     The payment of the proceeds of the disposition of Common Stock by or
through the United States office of a broker is subject to information reporting
and backup withholding at a rate of 31% unless the holder certifies its name,
address and non-United States status under penalties of perjury or otherwise
establishes an exemption. Information reporting requirements (but not backup
withholding) will apply to a payment of disposition proceeds by or through a
foreign office of (a) a United States broker, (b) a foreign broker that is a
"controlled foreign corporation" for United States federal income tax purposes
or (c) a foreign broker 50% or more of whose gross income for certain periods is
effectively connected with the conduct of a United States trade or business,
unless, in each case, such broker has documentary evidence in its files of the
owner's foreign status and has no actual knowledge to the contrary. Generally,
United States information reporting and backup withholding will not apply to a
payment of disposition proceeds if the payment is made outside the United States
by or through a foreign office of a non-U.S. broker.
 
     The Withholding Regulations will affect the procedures to be followed by a
Non-United States Holder in establishing such holder's status as a Non-United
States Holder for purposes of the withholding, backup withholding and
information reporting rules discussed herein. Among other things, the
Withholding Regulations will provide certain presumptions under which a
Non-United States Holder would be subject to backup withholding in the absence
of certification from the holder as to non-U.S. status. Prospective investors
should
 
                                       53
<PAGE>   55
 
consult their tax advisors concerning the effect of the Withholding Regulations
on an investment in Common Stock.
 
   
     Backup withholding is not an additional tax. Rather, the United States tax
liability of persons subject to backup withholding will be reduced by the amount
of tax withheld. If withholding results in an overpayment of taxes, a refund may
be obtained, provided that the required information is furnished to the IRS.
    
 
FEDERAL ESTATE TAXES
 
     Common Stock owned or treated as owned by an individual who is not a
citizen or resident of the United States (as specially defined for United States
federal estate tax purposes) at the time of death will be subject to United
States federal estate tax unless an applicable estate tax treaty provides
otherwise. Estates of non-resident aliens are generally allowed a statutory
credit which is the equivalent of an exclusion of $60,000 of assets from the
U.S. estate tax. Tax treaties may permit a larger credit.

     The nature of the respective obligations of the U.S. Underwriters and the
International Managers is such that all of the U.S. Shares and all of the
International Shares (other than those covered by the over-allotment option)
must be purchased if any are purchased. Those obligations are subject, however,
to various conditions, including the approval of certain matters by counsel. The
Company and the Selling Stockholders have agreed to indemnify the U.S.
Underwriters and the International Managers against certain liabilities,
including liabilities under the Securities Act, and, where such indemnification
is unavailable, to contribute to payments that the U.S. Underwriters and the
International Managers may be required to make in respect of such liabilities.

     The Company and the Selling Stockholders have been advised that the U.S.
Underwriters propose to offer the U.S. Shares in the United States and Canada
and the International Managers propose to offer the International Shares outside
the United States and Canada, initially at the public offering price set forth
on the cover page of this Prospectus and to certain selected dealers at such
price less a concession not to exceed $     per share; that the U.S.
Underwriters and the International Managers may allow, and such selected dealers
may reallow, a concession to certain other dealers not to exceed $     per
share; and that after the commencement of the Offerings, the public offering
price and the concessions may be changed.
 
     The Company and the Selling Stockholders have granted the U.S. Underwriters
and the International Managers options to purchase in the aggregate up to
1,200,000 additional shares of Common Stock solely to cover over-allotments, if
any. The options may be exercised in whole or in part at any time within 30 days
after the date of this Prospectus. To the extent options are exercised, the U.S.
Underwriters and the International Managers will be severally committed, subject
to certain conditions, to purchase the additional shares of Common Stock in
proportion to their respective commitments as indicated in the preceding tables.
 
     Pursuant to an Agreement Between U.S. Underwriters and International
Managers (the "Agreement Between U.S. Underwriters and International Managers"),
each U.S. Underwriter has represented and agreed that, with respect to the
shares included in the U.S. Offering and with certain exceptions, (a) it is not
purchasing any Common Stock for the account of anyone other than a United States
or Canadian Person (as defined below) and (b) it has not offered or sold, and
will not offer or sell, directly or indirectly, any Common Stock or distribute
this Prospectus outside of the United States or Canada or to anyone other than a
United States or Canadian Person. Pursuant to the Agreement Between U.S.
Underwriters and International Managers, each International Manager has
represented and agreed that, with respect to the shares included in the
International Offering and with certain exceptions, (a) it is not purchasing any
Common Stock for the account of any United States or Canadian Person and (b) it
has not offered or sold, and will not offer or sell, directly or indirectly, any
Common Stock or distribute this Prospectus within the United States or Canada or
to any United States or Canadian Person. The foregoing limitations do not apply
to stabilization transactions and to certain other transactions among the
International Managers and the U.S. Underwriters. As used herein, "United States
or Canadian Person" means any national or resident of the United States or
Canada or any corporation, pension, profit-sharing or other trust or other
entity organized under the laws of the United States or Canada or of any
political subdivision thereof (other than a branch located outside the United
States or Canada of any United States or Canadian Person) and includes any
United States or Canadian branch of a person who is not otherwise a United
States or Canadian Person, and "United States" means the United States of
America, its territories, its possessions and all areas subject to its
jurisdiction.
 
     Pursuant to the Agreement Between U.S. Underwriters and International
Managers, sales may be made between the U.S. Underwriters and the International
Managers of any number of shares of Common Stock to be purchased pursuant to the
Underwriting Agreement as may be mutually agreed. The per share price and
currency of settlement of any shares so sold shall be the public offering price
set forth on the cover page hereof, in United States dollars, less an amount not
greater than the per share amount of the concession to dealers set forth above.
 
     Pursuant to the Agreement Between U.S. Underwriters and International
Managers, each U.S. Underwriter has represented that it has not offered or sold,
and has agreed not to offer or sell, any Common Stock, directly or indirectly,
in Canada in contravention of the securities laws of Canada or any province or
territory thereof and has represented that any offer of Common Stock in Canada
will be made only pursuant to an exemption from the requirement to file a
prospectus in the province or territory of Canada in which such offer is made.
Each U.S. Underwriter has further agreed to send any dealer who purchases from
it any Common Stock a notice stating in substance that, by purchasing such
Common Stock, such dealer represents and agrees that it has not offered or sold,
and will not offer or sell, directly or indirectly, any of such Common Stock in
Canada in contravention of the securities laws of Canada or any province or
territory thereof and that any offer of Common Stock in Canada will be made only
pursuant to an exemption from the requirement to file a prospectus in the
province or territory of Canada in which such offer is made, and that such
dealer will deliver to any other dealer to whom it sells any of such Common
Stock a notice to the foregoing effect.

<PAGE>   58
 
     Pursuant to the Agreement Between U.S. Underwriters and International
Managers, each International Manager has represented and agreed that (i) it has
not offered or sold and during the period of six months from the date of this
Prospectus will not offer or sell any Common Stock to persons in the United
Kingdom except to persons whose ordinary activities involve them in acquiring,
holding, managing or disposing of investments (as principal or agent) for the
purposes of their businesses or otherwise in circumstances which do not
constitute an offer to the public in the United Kingdom for the purposes of the
Public Offers of Securities Regulations 1995 (the "Regulations"); (ii) it has
complied and will comply with all applicable provisions of the Financial
Services Act 1986 of Great Britain and the Regulations with respect to anything
done by it in relation to the Common Stock in, from or otherwise involving the
United Kingdom; and (iii) it has only issued or passed on and will only issue or
pass on in the United Kingdom any document in connection with the issue or sale
of the Common Stock to a person who is of a kind described in Article 11(3) of
the Financial Services Act 1986 (Investment Advertisements) (Exemptions) Order
1995 of Great Britain or is a person to whom the document may otherwise lawfully
be issued or passed on.
 
     No action has been taken in any jurisdiction by the Company or the U.S.
Underwriters or the International Managers that would permit a public offering
of the Common Stock offered pursuant to the Offerings in any jurisdiction where
action for that purpose is required, other than the United States. The
distribution of this Prospectus and the offering or sale of the shares of Common
Stock offered hereby in certain jurisdictions may be restricted by law.
Accordingly, the shares of Common Stock offered hereby may not be offered or
sold, directly or in directly, and neither this Prospectus nor any other
offering material or advertisements in connection with the Common Stock may be
distributed or published, in or from any jurisdiction, except under
circumstances that will result in compliance with applicable rules and
regulations of any such jurisdiction. Such restrictions may be set out in
applicable Prospectus supplements. Persons into whose possession this Prospectus
comes are required by the Company and the U.S. Underwriters and the
International Managers to inform themselves about and to observe any applicable
restrictions. This Prospectus does not constitute an offer of, or an invitation
to subscribe for purchase of, any shares of Common Stock and may not be used for
the purpose of an offer to, or solicitation by, anyone in any jurisdiction or in
any circumstances in which such offer or solicitation is not authorized or is
unlawful.
 
     The Senior Executive Officers and the Selling Stockholders, who
collectively are the beneficial owners of an aggregate of 18,180,240 shares of
Common Stock (14,180,420 shares after consummation of the Offerings), and the
Company, have agreed with the U.S. Underwriters and the International Managers,
subject to certain exceptions, not to, directly or indirectly, offer, sell,
contract to sell, grant any option to purchase or otherwise dispose of, without
the prior written consent of Bear Stearns, any shares of Common Stock or any
securities convertible into or exercisable or exchangeable for, or warrants,
options or rights to purchase or acquire, Common Stock or in any other manner
transfer all or a portion of the economic consequences associated with the
ownership of any Common Stock, or enter into any agreement to do any of the
foregoing, for a period of 90 days after the date of this Prospectus. See
"Shares Eligible for Future Sale."
 
     In order to facilitate the Offerings, certain persons participating in the
Offerings may engage in transactions that stabilize, maintain or otherwise
affect the price of the Common Stock during and after the Offerings.
Specifically, the U.S. Underwriters and the International Managers may
over-allot or otherwise create a short position in the Common Stock for their
own account by selling more shares of Common Stock than have been sold to them
by the Company. The U.S. Underwriters and the International Managers may elect
to cover any such short position by purchasing shares of Common Stock in the
open market or by exercising the over-allotment options granted to the U.S.
Underwriters and the International Managers. In addition, such persons may
stabilize or maintain the price of the Common Stock by bidding for or purchasing
shares of Common Stock in the open market and may impose penalty bids, under
which selling concessions allowed to syndicate members or other broker-dealers
participating in the Offerings are reclaimed if shares previously distributed in
the Offerings are repurchased in connection with stabilization transactions or
otherwise. The effect of these transactions may be to stabilize or maintain the
market price of the Common Stock at a level above that which might otherwise
prevail in the open market. The imposition of a penalty bid may also affect the
price of the Common Stock to the extent that it discourages resales thereof. No
 
                                       57
<PAGE>   59
 
representation is made as to the magnitude or effect of any such stabilization
or other transactions. Such transactions, if commenced, may be discontinued at
any time.
 
     Certain persons participating in the Offerings may engage in passive market
making transactions in the Common Stock on the Nasdaq National Market in
accordance with Rule 103 of Regulation M under the 1934 Act. Rule 103 permits,
upon the satisfaction of certain conditions, underwriting and selling group
members participating in a distribution that are also registered Nasdaq market
makers in the security being distributed (or a related security) to engage in
limited passive market making transactions during the period when Regulation M
would otherwise prohibit such activity. In general, a passive market maker may
not bid for or purchase a security at a price that exceeds the highest
independent bid for those securities by a person that is not participating in
the distribution and must identify its passive market making bids on the Nasdaq
electronic inter-dealer reporting system. In addition, the net daily purchases
made by a passive market maker generally may not exceed 30% of such market
maker's average daily trading volume in the security for the two full
consecutive calendar months (or any 60 consecutive days ending within 10 days)
immediately preceding the date of filing of the Registration Statement of which
this Prospectus forms a part.
 
     Certain of the U.S. Underwriters and International Managers have in the
past provided, and may in the future provide, investment banking services for
the Company. In particular, Bear Stearns, DLJ and Adams, Harkness & Hill, Inc.
and certain of their respective affiliates served as underwriters for the
Company's initial public offering in November 1996. In addition, in May 1996 DLJ
acted as an initial purchaser of the Company's 10 1/4% Senior Subordinated Notes
due 2006.
 
   
     DLJ Investment Partners, L.P., DLJ Investment Funding, Inc. and DLJ First
ESC L.P. (collectively, the "DLJ Affiliates"), each of which is an affiliate of
DLJ, are collectively the owners of 323,750 shares of Common Stock and will be
Selling Stockholders in the Offerings. The DLJ Affiliates will be selling
131,455 shares in the Offerings and as a result will receive approximately $4.9
million of the net proceeds of the Offerings (using an assumed offering price of
$38.875 per share). In addition, Bear Stearns and DLJ each have in the past
provided, and may in the future provide, investment banking services for GEI and
its affiliates. Affiliates of Bear Stearns and DLJ each own approximately 1.6%
of the limited partnership interests in GEI.

     The validity of the shares offered hereby will be passed upon for the

                          INDEPENDENT AUDITORS' REPORT
 
To the Shareholders of
Twinlab Corporation and subsidiaries
Ronkonkoma, New York
 
     We have audited the accompanying consolidated balance sheets of Twinlab
Corporation and subsidiaries as of December 31, 1996 and 1997, and the related
consolidated statements of income, shareholders' equity and cash flows for each
of the three years in the period ended December 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Twinlab Corporation and
subsidiaries as of December 31, 1996 and 1997, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1997 in conformity with generally accepted accounting principles.

affiliates, Twinlab Export Corp. ("Export"), Twinlab Specialty Corporation
("Specialty"), Alvita Products, Inc. ("Alvita"), Natur-Pharma, Inc.
("Natur-Pharma"), B. Bros. Realty Corporation ("B. Bros.") and Advanced Research
Press, Inc. ("ARP") (collectively, the "Companies") operated as separate
corporations, all of which were wholly-owned by the same individuals (with some
companies having different ownership percentages among such individuals) except
for Natur-Pharma and B. Bros., which were 97 percent owned by such individuals.
 
     On February 27, 1996, Twinlab Corporation (formerly TLG Laboratories
Holding Corp.) ("Twinlab") was incorporated in contemplation of the Acquisition
(as hereinafter defined). The accompanying consolidated financial statements
include the accounts of Twinlab and subsidiaries (the "Company") after giving
retroactive effect, in a manner similar to a pooling of interests, to the merger
of the Companies pursuant to the Acquisition.
 
     The shareholders of the Companies entered into a stock purchase and sale
agreement dated as of March 5, 1996 and which was consummated on May 7, 1996
pursuant to which (i) Green Equity Investors II, L.P. ("GEI") acquired 8,880,000
shares (adjusted for the 18.5 for 1 stock split -- see Note 9a) (48 percent) of
the common stock of Twinlab for aggregate consideration of $4,800 and shares of
11.25 percent non-voting junior redeemable preferred stock of Twinlab (the
"Junior Preferred Stock") for aggregate consideration of $37,000, (ii) certain
other investors acquired 1,295,000 shares (adjusted for the 18.5 for 1 stock
split -- see Note 9a) (7 percent) of the common stock of Twinlab (each of these
other investors owns less than 5 percent of the common stock of Twinlab) for
aggregate consideration of $700 and shares of 14 percent non-voting senior
redeemable preferred stock of Twinlab for aggregate consideration of $30,000
(the "Senior Preferred Stock", and together with the Junior Preferred Stock, the
"Preferred Stock"), (iii) certain of the shareholders of the Companies (the
"Continuing Shareholders") exchanged certain of their shares of common stock of
Natur-Pharma for 8,325,000 shares (adjusted for the 18.5 for 1 stock
split -- see Note 9a) (45 percent) of the outstanding shares of common stock of
Twinlab, valued at $4,500, (iv) Twinlab purchased all of the remaining shares of
common stock of Natur-Pharma from the existing shareholders for cash, resulting
in Natur-Pharma becoming a wholly-owned subsidiary of Twinlab, (v) Old Twin,
Alvita, Export, Specialty, and B. Bros. merged into Natur-Pharma and ARP merged
with Natur-Pharma II, Inc., a wholly-owned subsidiary of Natur-Pharma (the
surviving entity in such merger is referred to herein as "ARP"), and (vi) in
connection with such mergers, the existing shareholders received cash in
consideration for all their shares of capital stock of Old Twin, Alvita, Export,
Specialty, B. Bros., and ARP. The total cash consideration that the existing
shareholders received was approximately $212,500, approximately $15,300 of which
represented consideration for non-competition agreements with each of the
existing shareholders, which was recognized as a nonrecurring expense upon the
consummation of the Acquisition. The transactions described above are
hereinafter referred to as the "Acquisition." Concurrently with the consummation
of the Acquisition, the Company entered into a credit facility (which provided
for a term loan facility in the amount of $53,000 and a revolving credit
facility in the amount of $15,000) (the "Original Credit Facility") and issued
$100,000 aggregate principal amount of senior subordinated notes in a private
placement (the "Note Offering", and, collectively with the Acquisition and the
Original Credit Facility, the "Transactions"), which notes were subsequently
exchanged in October 1996 for publicly registered notes. The net cash proceeds
of the Note Offering were used, together with borrowings under the Original
Credit Facility, the proceeds from the issuance of the common stock and
Preferred Stock of Twinlab and available cash of the Company, to finance the
Acquisition, to refinance approximately $7,000 aggregate principal amount of
debt of the Company and to pay related fees and expenses. In connection with the
Acquisition, Natur-Pharma's name was changed to Twin Laboratories Inc. ("Twin").
In connection with the Transactions, the Company has expensed $656 and $400 of
professional fees for the year ended December 31, 1995 and 1996, respectively
(the "Transaction Expenses").

                  (DOLLAR AMOUNTS ARE IN THOUSANDS OF DOLLARS)
 
     Because the Acquisition did not result in a change in control as defined in
Emerging Issues Task Force Issue No. 88-16, "Basis in Leveraged Buyout
Transactions" ("EITF 88-16"), the transactions were accounted for as a
recapitalization under the guidance of EITF 88-16 and the Companies' historical
basis of accounting were applied to the consolidated financial statements of
Twinlab.
 
     The Company manufactures and markets high quality nutritional products,
including a complete line of vitamins, minerals, and nutraceuticals,
antioxidants, fish and marine oils and sports nutrition supplements through its
Twinlab Division; a full line of herbs and phytonutrients through its Nature's
Herbs Division; herbal teas through its Alvita Division; and a line of
nutritional supplements through its network marketing subsidiary, Changes
International of Fort Walton Beach, Inc. ("Changes International"). Twinlab
Corporation also publishes "All Natural Muscular Development", a sports and
fitness magazine, and health and fitness related books, audios, and newsletters
through its publishing subsidiary, ARP.
 
     The following unaudited pro forma results of operations assume the
Transactions occurred on January 1, 1995 and excludes the effect of (i) the
nonrecurring non-competition agreement expense, and (ii) the Transaction
Expenses, and reflects the additional interest expense relating to the financing
of the Acquisition and the change in tax status. The pro forma operations data

     On November 15, 1996, the Company consummated an initial public offering of
common stock (the "IPO"), with the sale to the public of 8,500,000 shares of
common stock at $12.00 per share. In connection with the consummation of the
IPO, the Company entered into an amended credit agreement which provides for a
revolving credit facility of $50,000 (the "Revolving Credit Facility") (see Note
8). The net proceeds to the Company of the IPO of approximately $93,666 (after
underwriters' discounts of $6,630 and offering expenses of $1,704), together
with available cash resources of the Company and approximately $20,000 of
borrowings under the Revolving Credit Facility, were used to repay all of the
Company's outstanding indebtedness under the term loan contained in the Original
Credit Facility, plus accrued and unpaid interest thereon of approximately $233,
and to redeem all of the outstanding shares of Preferred Stock having an
aggregate liquidation preference of $67,000, plus accrued and unpaid dividends
thereon of approximately $4,862 (the "Repayments"). In connection with the
prepayment of outstanding indebtedness under the term loan facility and the
establishment of the Revolving Credit Facility, the Company recorded an
extraordinary charge representing the write-off of previously deferred finance
costs incurred in connection with the Original Credit Facility of approximately
$1,792 (net of tax benefit of $1,134).

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     A. PRINCIPLES OF CONSOLIDATION -- All material intercompany accounts and
transactions have been eliminated.
 
     B. CASH EQUIVALENTS -- Investments with original maturities of three months
or less are considered cash equivalents.
 
     C. INVENTORIES -- Inventories are stated at the lower of cost (first-in,
first-out method) or market value.
 
     D. PROPERTY, PLANT AND EQUIPMENT -- Depreciation is computed using the
straight-line method based upon the estimated useful lives of the related assets
which range from three to forty years. Amortization of leasehold improvements is
computed by the straight-line method over the shorter of the estimated useful
lives of the related assets or lease term.
 
     E. INTANGIBLE ASSETS -- Trademarks are being amortized on the straight-line
method over their expected lives, not to exceed forty years. Goodwill, which
represents the excess of purchase price over fair value of net assets acquired,
is being amortized on the straight-line method over periods ranging from twenty
to forty years. Other intangible assets acquired in connection with Changes
International are being amortized on the straight-line method over five years.
 
     F. INCOME TAXES -- The Company accounts for income taxes under the
provisions of Statement of Financial Accounting Standards ("SFAS") No. 109,
"Accounting For Income Taxes", which requires recognition of deferred tax assets
and liabilities for the expected future tax consequences of events that have
been included in the Company's financial statements or tax returns. Under this
method, deferred tax assets and liabilities are determined based on the
differences between the financial accounting and tax bases of assets and
liabilities using enacted tax rates in effect for the year in which the
differences are expected to reverse.
 
     G. REVENUE RECOGNITION -- Revenue from product sales is recognized at the
time of shipment to the customer. Revenue from magazine subscriptions is
recorded as deferred revenue at the time of sale and a pro rata share is
included in revenue as magazines are delivered to subscribers. Advertising
revenue is recognized when the related magazines are issued.
 
     H. RESEARCH AND DEVELOPMENT EXPENSES -- The Company charges research and
development expenses to operations as incurred. Research and development
expenses were $1,140, $1,119 and $1,095 for the years ended December 31, 1995,
1996 and 1997, respectively.
 
     I. EARNINGS PER SHARE -- The Company retroactively adopted SFAS No. 128,
"Earnings Per Share" during 1997. SFAS No. 128 changed the computation,
presentation and disclosure requirements for earnings per share. SFAS No. 128
requires presentation of "basic" and "diluted" earnings per share. The adoption
of SFAS No. 128 did not have a material impact on the Company's income per
share.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
              FOR THE YEARS ENDED DECEMBER 31, 1995, 1996 AND 1997
                  (DOLLAR AMOUNTS ARE IN THOUSANDS OF DOLLARS)
 
     J. IMPAIRMENT OF LONG-LIVED ASSETS -- In accordance with SFAS No. 121,
"Accounting For the Impairment of Long-Lived Assets and For Long-Lived Assets To
Be Disposed Of", the Company reviews its long-lived assets, including property
and equipment, goodwill and intangible assets for impairment whenever events or
changes in circumstances indicate that the carrying amount of the assets may not
be fully recoverable. To determine recoverability of its long-lived assets, the
Company evaluates the probability that future undiscounted net cash flows will
be less than the carrying amount of the assets. Impairment costs, if any, are
measured by comparing the carrying amount of the related assets to their fair
value.
 
     K. USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS -- The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
     L. RECLASSIFICATIONS -- Certain prior year balances have been reclassified
to conform with current year classifications.
 
3.  ACQUISITION
 
     In November 1997, the Company acquired all of the outstanding shares of
Changes International. Changes International is a network marketer of
nutritional supplements. The Company paid $7,888 in cash, including acquisition
costs, and issued 312,500 shares of its common stock (which had a market value
of approximately $5,859 on the date of the acquisition).
 
     This acquisition has been accounted for as a purchase and, accordingly, the
results of Changes International are included in the consolidated statements of
income of the Company since the date of acquisition and the purchase price
(including acquisition costs) has been allocated on a preliminary basis to net
assets acquired based upon their fair values. Goodwill relating to the
acquisition of $10,768 is being amortized over 20 years. The following unaudited
pro forma information assumes that the acquisition of Changes International had
occurred as of January 1, 1996, including the impact of the amortization expense
associated with intangible assets acquired, increased interest expense on
acquisition debt and related income tax effects. The pro forma operations data
has been prepared for comparative purposes only and does not purport to
represent what the Company's actual results of operations would have been had
the acquisition, in fact, occurred on January 1, 1996.

(a) The Revolving Credit Facility expires on May 7, 2002 and provides for
    borrowings up to $50,000. Borrowings under the Revolving Credit Facility
    bear interest, at the Company's discretion, at either the Alternative Base
    Rate, as defined, or at the Eurodollar Rate (maximum six-month term), plus a
    margin of 1.25 percent, as defined. The effective interest rate on
    borrowings under the Revolving Credit Facility ranged from 6.75 to 8.5
    percent as of December 31, 1997. Interest rates are subject to increases or
    reduction based upon Twin's meeting certain financial tests. The proceeds of
    the Revolving Credit Facility are available for working capital requirements
    and for general corporate purposes, including up to $35,000 of which is
    available to fund permitted acquisitions, as defined, subject to certain
    conditions and reductions. (At December 31, 1997, approximately $21,250 of
    this portion of the Revolving Credit Facility was available to fund
    permitted acquisitions). A portion of the Revolving Credit Facility not to
    exceed $15,000 is available for the issuance of letters of credit which
    generally have an initial term of one year or less. The Revolving Credit
    Facility is secured by first priority security interests in all of the
    tangible and intangible assets of Twin and its direct subsidiaries and is
    guaranteed by Twinlab, ARP, and Changes International. In addition, the
    Revolving Credit Facility contains certain restrictive covenants including,
    among other things, the maintenance of certain debt coverage ratios, as well
    as restrictions on additional indebtedness, dividends and certain other
    significant transactions. The Company was in compliance with all such
    covenants as of December 31, 1997.
    
 
(b) The senior subordinated notes mature on May 15, 2006 and bear interest at a
    rate of 10 1/4 percent per annum. The senior subordinated notes are jointly
    and severally guaranteed by Twinlab, ARP, and Changes International on a
    full and unconditional unsecured senior subordinated basis. The senior
    subordinated notes are callable after five years at a premium to par which
    declines to par after eight years. Until May 15, 1999, Twin has the option
    to redeem up to 35 percent of the subordinated notes with the proceeds of a
    public offering at a redemption price of 109 1/2 percent. Upon a change of
    control, as defined,

    Twin is required to offer to redeem the subordinated notes at 101 percent of
    the principal amount plus accrued and unpaid interest. Restrictive covenants
    contained in the indenture governing the subordinated notes (the "Note
    Indenture") include, among other things, limitations on additional
    indebtedness, investments, dividends and certain other significant
    transactions. The Company was in compliance with all such covenants as of
    December 31, 1997.
 
     The Revolving Credit Facility and the Note Indenture restrict the payment
of dividends and the making of loans, advances or other distributions of assets
to Twinlab, except in certain limited circumstances.

9.  SHAREHOLDERS' EQUITY
 
     (a) CHANGES IN AUTHORIZED CAPITAL AND STOCK SPLIT -- In July 1996, the
Board of Directors (the "Board") and the stockholders authorized an increase in
the number of common shares authorized to 75,000,000 and an increase in the
number of shares of preferred stock authorized to 2,000,000, which preferred
stock may be issued by the Board on such terms and with such rights, preferences
and designations as the Board may determine, without further stockholder action.
Prior to the IPO, on November 15, 1996, the Board authorized a stock split
(effected in the form of a stock dividend) of all issued and outstanding common
shares at the rate of 18.5 for 1, which increased the number of issued and
outstanding shares from 1,000,000 to 18,500,000. The stock split and the change
in authorized common stock have been retroactively reflected for purposes of
calculating income per share for all periods presented herein.
 
     (b) STOCK INCENTIVE PLAN -- In November 1996, the Board and stockholders of
the Company approved and adopted the Twinlab Corporation 1996 Stock Incentive
Plan (the "1996 Plan"). The 1996 Plan provides for the issuance of a total of up
to 400,000 authorized and unissued shares of common stock, treasury shares
and/or shares acquired by the Company for purposes of the 1996 Plan. Awards
under the 1996 Plan may be made in the form of (i) incentive stock options; (ii)
nonqualified stock options; (iii) stock appreciation rights; (iv) restricted
stock; and (v) performance shares. Options become exercisable over five years
from the date of grant at the rate of 20 percent of the grant each year and
expire up to ten years after the date of grant. On November 14, 1996, the Board
granted 120,000 nonqualified stock options under the 1996 Plan to certain key
persons at an exercise price equal to the initial public offering price of
$12.00 per share.

</TABLE>
 
     The Company applies Accounting Principles Board Opinion No. 25, "Accounting
For Stock Issued To Employees", and selected interpretations in accounting for
the 1996 Plan. Accordingly, as all options have been granted at exercise prices
equal to fair market value on the date of grant, no compensation expense has
been recognized by the Company in connection with its stock-based compensation
plan. Had compensation cost for the Company's 1996 Plan been determined based
upon the fair value at the grant date for awards under the 1996 Plan consistent
with the methodology prescribed under Statement of Financial Accounting
Standards No. 123, "Accounting For Stock-Based Compensation", the Company's net
income would have been reduced by approximately $14 and $188 in 1996 and 1997,
respectively. The weighted average fair value of the options granted during 1996
and 1997 is estimated at $6.81 and $10.89 on the date of grant (using
Black-Scholes option pricing model) with the following weighted average
assumptions for 1996 and 1997, respectively: volatility of 45 percent and 46
percent, risk-free interest rate of 6.09 percent and 5.75 percent, and an
expected life of seven years.

     c. NET INCOME PER SHARE -- In 1997, the Company adopted SFAS No. 128,
"Earnings Per Share". Basic income per share is determined by using the weighted
average number of shares of common stock outstanding during each period. Diluted
income per share further assumes the issuance of common shares for all dilutive
outstanding common stock options. The calculation for income before
extraordinary item per share for each of the three years ended December 31, 1997

(a) Amount assumes, as outstanding for the entire year, the 10,175,000 shares
    (adjusted for the 18.5 for one stock split -- see Note 9a) issued in
    connection with the Acquisition and the 8,500,000 shares issued in
    connection with the IPO (see Note 1).
 
10.  INCOME TAXES
 
     Prior to the consummation of the Acquisition, all of the Companies were "S"
corporations and as such Federal and state taxes were generally paid at the
shareholder level only. The provision for income taxes for the year ended
December 31, 1995 and through the consummation of the Acquisition on May 7, 1996
represents state taxes for those states that impose a tax on "S" corporations.
 
     Upon consummation of the Acquisition, the Companies terminated their S
Corporation status. The mergers of Old Twin, Alvita, Export, Specialty and B.
Bros. into Natur-Pharma were treated as taxable asset purchases for Federal and
state income tax purposes and a recapitalization for financial accounting
purposes. For Federal and state income tax purposes, the purchase price was
allocated among the various corporations and their respective assets and
liabilities based on the respective fair values as of the closing of the
Acquisition. This resulted in different book and tax asset bases for the assets
of these companies, which resulted in deferred tax assets of approximately
$55,571.

11.  EMPLOYEE BENEFIT PLANS
 
     Old Twin provided a profit sharing plan, and Natur-Pharma provided an
Employee Savings and Investment Plan to all eligible employees, as defined,
through July 1, 1996. Effective July 1, 1996, the Company adopted the Twin
Laboratories Inc. 401(k) Plan (the "401(k) Plan") which is an amendment and
restatement of the Old Twin profit sharing plan and merged the Natur-Pharma
Employee Savings and Investment Plan into the 401(k) Plan.
 
     Eligible employees may contribute up to 15 percent of their annual
compensation, subject to certain limitations, and the Company will match 50
percent of an employee's contribution. Total provisions with respect to these
plans approximated $287, $164 and $375 for the years ended December 31, 1995,
1996 and 1997, respectively.

12.  COMMITMENTS AND CONTINGENCIES
 
     A. LEASES -- The Company leases certain warehouse space and equipment under
operating leases. Generally, the leases carry renewal provisions and require the
payment of maintenance costs. Rental payments may be adjusted for increases in
taxes and other costs above specific amounts. Rental expense charged to
operations for the years ended December 31, 1995, 1996 and 1997 was
approximately $1,370, $1,579, and $1,874, respectively.
 
     Future minimum payments under noncancellable operating leases with initial
or remaining terms of more than one year are as follows:

     During 1997, the Company entered into several agreements for the sale and
leaseback of certain production equipment. The Company received $3,099 which
approximated the net book value of the assets sold. These leases have been
classified as operating leases.
 
     B. LEGAL MATTERS -- The Company, like various other participants in the
nutritional supplement industry, has been a defendant in court actions seeking
damages for alleged personal injuries resulting from products containing
allegedly contaminated added manufactured L-Tryptophan. To date, 132 of the 133
suits in which the Company was a named defendant (the "L-Tryptophan Actions")
have been dismissed or settled at no cost to the Company pursuant to an
indemnification agreement (the "Indemnification Agreement") between the Company
and a U.S. subsidiary of the Japanese manufacturer of the allegedly contaminated
ingredient. The Company believes, after consultation with outside counsel, that
few new lawsuits are likely to be brought in view of applicable statutes of
limitation. Based upon consultation with outside counsel, the Company also
believes that , in light of the Indemnification Agreement and the resolution of
virtually all of the L-Tryptophan Actions at no cost to the Company, the
prospect of the remaining L-Tryptophan Actions and any possible future actions
having a material adverse effect on the Company's consolidated financial
statements is remote. The Company no longer markets any products containing
added manufactured L-Tryptophan.
 
     The Company is also engaged in various other litigation in the ordinary
course of business. Management is of the opinion that the amounts which may be
awarded or assessed, if any, in connection with these matters will not have a
material adverse effect on the consolidated financial statements.
 
13.  MAJOR CUSTOMERS AND CREDIT CONCENTRATIONS
 
     The Company has two significant customers which accounted for approximately
27 and 21 percent, respectively, of net sales for 1995; 25 and 20 percent,
respectively, of net sales for 1996; and 19 and 23 percent, respectively, of net
sales for 1997. No other customer accounted for more than 10 percent of net
sales in any of the three years ended December 31, 1997.

     The Company's customers are primarily large independent distributors of
health food products. At December 31, 1996 and 1997, approximately 64 and 58
percent, respectively, of accounts receivable related to two customers.
 
14.  CONDENSED AND SUMMARIZED FINANCIAL INFORMATION
 
     As noted in Note 8b, the Revolving Credit Facility and the Note Indenture
restrict the payment of dividends and the making of loans, advances, or other
distributions to Twinlab, except in certain limited circumstances. After giving
retroactive effect, in a manner similar to a pooling of interests, to the merger
of the Companies pursuant to the Acquisition, the condensed financial
information of Twinlab, on a stand-alone basis, is as follows (because Twinlab
had no cash prior to the consummation of the Acquisition, no condensed statement
of cash flows is presented for the year ended December 31, 1995):

     Twin is a direct wholly-owned subsidiary of Twinlab. ARP and Changes
International are indirect wholly-owned subsidiaries of Twinlab. Twinlab, ARP
and Changes International have provided joint and several full and unconditional
senior subordinated guarantees of the senior subordinated notes of Twin (see
Note 8b).
 
     The assets, results of operations and shareholders' equity of Twin comprise
substantially all of the assets, results of operations and shareholders' equity
of Twinlab on a consolidated basis. Twinlab has no separate operations and has
no significant assets other than Twinlab's investment in Twin and, through Twin,
in ARP and Changes International. Twin has no direct or indirect subsidiaries
other than ARP and Changes International; Twin has no other stockholder than
Twinlab. Accordingly, the Company has determined that separate financial
statements of Twin, ARP and Changes International would not be material to
investors and, therefore, are not included herein.

15.  SUBSEQUENT EVENTS (UNAUDITED)
 
   
     A. PROPOSED PUBLIC OFFERING -- In February 1998, the Company determined to
work towards a proposed public offering of the Company's common stock (the
"Offering") on a firm commitment basis. The proposed Offering contemplates that
a total of 8,000,000 shares of common stock will be offered to the public, of
which 4,000,000 shares will be sold by certain of the Company's stockholders.
The net proceeds to the Company from the Offering are estimated to be
approximately $147,700. Of the net proceeds to the Company, approximately
$56,500 will be used to pay the purchase price for the Bronson Acquisition (as
defined in Note 15.b.), including related fees and expenses; approximately
$40,100 will be used to exercise the Company's option to redeem $35,000 of the
senior subordinated notes at a redemption price of 109 1/2 percent, plus accrued
and unpaid interest; and approximately $5,600 will be used to reduce outstanding
borrowings under the Revolving Credit Facility, including accrued and unpaid
interest. The remaining net proceeds to the Company will be used for working
capital and other general corporate purposes.
    
 
     B. POTENTIAL ACQUISITION -- On March 17, 1998, the Company entered into a
definitive agreement to acquire substantially all of the assets and assume
certain liabilities of the Bronson division ("Bronson") of Jones Medical
Industries, Inc. (the "Bronson Acquisition"). The Company expects that the
closing of the Bronson Acquisition will occur during the second quarter of
fiscal 1998. Bronson's net sales and operating income for the fiscal year ended
December 31, 1997, were approximately $32,105, and $9,505, respectively. The
purchase price is $55,000 in cash (excluding related fees and expenses), subject
to certain adjustments, which the Company intends to finance with a portion of
the net proceeds of the Offering. In the event the Offering is not consummated,
the Company would seek to amend its Revolving Credit Facility to increase the
permitted borrowings and to finance the Bronson Acquisition with borrowings
thereunder.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Reference is made to Section 102(b)(7) of the Delaware General Corporation
Law (the "DGCL"), which permits a corporation in its certificate of
incorporation or an amendment thereto to eliminate or limit the personal
liability of a director for violations of the director's fiduciary duty, except
(i) for any breach of the director's fiduciary duty of loyalty to the
corporation or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii)
pursuant to Section 174 of the DGCL (providing for liability of directors for
unlawful payment of dividends or unlawful stock purchases or redemptions), or
(iv) for any transaction from which the director derived an improper personal
benefit. The Company's Second Amended and Restated Certificate of Incorporation
contains provisions permitted by Section 102(b)(7) of the DGCL.
 
     Reference is made to Section 145 of the DGCL which provides that a
corporation may indemnify any persons, including directors and officers, who
are, or are threatened to be made, parties to any threatened, pending or
completed legal action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of such
corporation), by reason of the fact that such person is or was a director,
officer, employee or agent of such corporation, or is or was serving at the
request of such corporation as a director, officer, employee or agent of another
corporation or enterprise. The indemnity may include expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding, provided such director, officer, employee or agent acted in good
faith and in a manner he reasonably believed to be in or not opposed to the
corporation's best interests and, with respect to any criminal actions or
proceedings, had no reasonable cause to believe that his conduct was unlawful. A
Delaware corporation may indemnify directors and/or officers in an action or
suit by or in the right of the corporation under the same conditions, except
that no indemnification is permitted without judicial approval if the director
or officer is adjudged to be liable to the corporation. Where a director or
officer is successful on the merits or otherwise in the defense of any action
referred to above, the corporation must indemnify him or her against the
expenses which such director or officer actually and reasonably incurred.
 
     The Company's Second Amended and Restated Certificate of Incorporation and
Amended and Restated By-laws provide for the indemnification of directors and
officers of the Company to the fullest extent permitted by the DGCL.
 
                                      II-1

     Pursuant to the Underwriting Agreement filed as Exhibit 1.1 to this
Registration Statement, the Underwriters have agreed to indemnify the directors,
officers and controlling persons of the Company against certain civil
liabilities that may be incurred in connection with the Offering, including
certain liabilities under the Securities Act.
 
     The Company provides liability insurance for each director and officer for
certain losses arising from claims or charges made against them while acting in
their capacities as directors or officers of the Company.

ITEM 17.  UNDERTAKINGS.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the Company
pursuant to provisions described in Item 15 above, or otherwise, the Company has
been advised that, in the opinion of the Commission, such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Company of expenses incurred or paid
by a director, officer or controlling person of the Company in the successful
defense of any action, suit or proceeding) is asserted by such director, officer
or controlling person in connection with the Common Stock covered hereby, the
Company will, unless in the opinion of its counsel the matter has been settled
by controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
 
     The Company hereby undertakes that:
 
          (a) For purposes of determining any liability under the Securities
              Act, each filing of the Company's annual report pursuant to
              Section 13(a) or 15(d) of the 1934 Act (and, where applicable,
              each filing of an employee benefit plan's annual report pursuant
              to Section 15(d) of the 1934 Act) that is incorporated by
              reference in the registration statement shall be deemed to be a
              new registration statement relating to the Common Stock therein,
              and the offering of such Common Stock at that time shall be deemed
              to be the initial bona fide offering thereof.
                                      II-2
<PAGE>   85
 
          (b) For purposes of determining any liability under the Securities
              Act, the information omitted from the form of prospectus filed as
              part of this Registration Statement in reliance upon Rule 430A and
              contained in a form of prospectus filed by the Company pursuant to
              Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be
              deemed to be part of this Registration Statement as of the time it
              was declared effective.
 
          (c) For the purpose of determining any liability under the Securities
              Act, each post-effective amendment that contains a form of
              prospectus shall be deemed to be a new registration statement
              relating to the securities offered therein, and the offering of
              such securities at that time shall be deemed to be the initial
              bona fide offering thereof.
 
     The Company hereby undertakes to deliver or cause to be delivered with the
Prospectus, to each person to whom the Prospectus is sent or given, the latest
annual report to security holders that is incorporated by reference in the
Prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3
or Rule 14c-3 under the 1934 Act.
 
     The Company hereby undertakes to provide to the Underwriters at the closing
specified in the Underwriting Agreement, certificates in such denominations and
registered in such names as required by the Underwriters to permit prompt
delivery to each purchaser.
