PROSPECTUS SUPPLEMENT DATED DECEMBER 22, 1999
to
Prospectus Dated September 16, 1999
12,050,000 Shares
Interleukin Genetics, Inc.
Common Stock
This Prospectus Supplement supplements the Prospectus dated September 16,
1999 (the "Prospectus") of Interleukin Genetics, Inc. (the "Company") relating
to the public offering, which is not being underwritten, and sale by certain
shareholders of the Company or by their respective pledgees or donees, that
receive such shares as a gift or other non-sale related transfer (the "Selling
Shareholders") of 12,050,000 shares (the "Shares") of Common Stock, no par value
per share, of the Company (the "Common Stock"). This Prospectus Supplement
should be read in conjunction with the Prospectus, and this Prospectus
Supplement is qualified by reference to the Prospectus except to the extent that
the information herein contained supersedes the information contained in the
Prospectus. Capitalized terms used in this Prospectus Supplement and not
otherwise defined herein have the meanings specified in the Prospectus.
SELLING SHAREHOLDERS
Since the date of the Prospectus, certain Selling Shareholders (the
"Donors") have donated a portion of their respective shares of Common Stock (the
"Donated Shares") to two (2) different organizations and four (4) individuals
(collectively, the "Donees"), and the Donees were not specifically named in the
Prospectus. The Donees have requested that they be included as Selling
Shareholders in the Prospectus. Accordingly, the Selling Shareholders section of
the Prospectus is hereby supplemented to include the Donees (listed below), each
with respect to its Donated Shares. The total number of Shares offered by all
Selling Shareholders (including the Donor and Donees), however, remains
unchanged because each Donee is offering to sell all of their respective Donated
Shares.
