PROSPECTUS SUPPLEMENT DATED JULY 7, 2000
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, as supplemented by Prospectus Supplements dated December 22, 1999, March
20, 2000 and May 16, 2000 (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, a certain Selling Shareholder (the
"Transferor") has distributed 1,335,200 of the Shares (the "Transferred Shares")
to its five (5) members (the "Transferees"), and the Transferees were not
specifically named in the Prospectus. The Transferees have requested to be
included as Selling Shareholders in the Prospectus. Accordingly, the Selling
Shareholders section of the Prospectus is hereby supplemented to include the
Transferees (listed below), with respect to the Transferred Shares. The total
number of Shares offered by all Selling Shareholders (including the Transferor
and the Transferees), however, remains unchanged because the Transferees are
offering to sell only the Transferred Shares.
