     Interleukin Genetics Reports Third Quarter Financial Results

   WALTHAM, Mass.--(BUSINESS WIRE)--Nov. 11, 2003--Interleukin
Genetics, Inc. (OTCBB: ILGN) a leader in the development of DNA
testing products to help identify risk for diseases in which
inflammation plays a key role today reported financial results for the
quarter ended September 30, 2003.

   Third Quarter Financial Results:

   Revenues for the quarter were $634,000 compared to $80,000 in the
third quarter of 2002. In 2003 the revenue included $625,000 in
research revenue and approximately $5,000 from test revenue.
Approximately $9,000 of the 2002 revenue was test revenue. The
increase in revenue was due to $625,000 in revenue from our research
agreement with an affiliate of Alticor.
   Research and development expense decreased to $374,000 during the
three months ended September 30, 2003 from $717,000 for the same
quarter in 2002. This decrease was primarily the result of
reallocating resources from internally-funded research projects to the
research projects funded by Alticor whose costs are included in costs
of revenue and also a decrease in the number of external research
projects being funded by us. Selling, general and administrative
expenses decreased approximately 26% to $482,000 for the quarter from
$653,000 during the same period last year. This decrease was primarily
the result of higher legal expenses incurred in 2002 related to
financing activities in that year.
   For the quarter, the company reported a net loss of $767,000 or
$.03 per basic and diluted share as compared to a net loss of
$1,364,000 or $.06 per basic and diluted share for the same period
last year.
   As of September 30, 2003, the company reported cash and cash
equivalents of $5,071,000 as compared with $734,000 at December 31,
2002.
   "We continue to be very excited about our strategic alliance with
Alticor." Stated Dr. Philip Reilly, Chief Executive Officer of the
company. "This alliance has provided us with a foothold in the
developing Personalized Nutrition market and has given us access to a
world-wide distribution network through which to sell our predictive
testing products."
   For the nine months ended September 30, 2003, the Company reported
revenues of $1,295,000 and net loss of $3,381,000 or $0.15 per share
as compared to revenues of $102,000 and net loss of $4,226,000 or
$0.20 per share for the same period last year.
