INTERLEUKIN GENETICS REPORTS THIRD QUARTER 2008 FINANCIAL RESULTS

WALTHAM, MA – November 13, 2008 - Interleukin Genetics, Inc. (AMEX: ILI) today announced financial and business results for the third quarter ended September 30, 2008.

The Company reported a net loss of $1.6 million, or $(.05) per basic and diluted common share, for the third quarter of 2008 compared to a net loss of $1.1 million, or $(.04) per basic and diluted common share, for the same period last year.

“Collaborations are an important element of Interleukin Genetics’ strategic plan to distribute and develop new, high value genetic tests, and we were pleased to lay significant groundwork for new partnerships this quarter,” commented Lewis H. Bender, Chief Executive Officer.  “Our revised agreement with Access Business Group International, the product development group at Alticor, now provides us with the opportunity to pursue new partners to help distribute our genetic tests and to form additional collaborations around our intellectual property.  In addition, we  executed a new license agreement with OralDNA to market our PST Genetic Test as an assessment of risk for periodontal disease and established a research collaboration with Geisinger Health System to explore the role of genetics in obesity.”

Revenue for the third quarter of 2008 was $2.2 million, compared to $2.6 million for the same period last year.  The decrease in revenue is attributable to a decrease in consumer product sales and lower contract research and development revenue from Alticor.

Research and development expenses were $933,000 for the third quarter of 2008 compared to $786,000 for the same period last year.  The increase is primarily attributable to expenses relating to the Company’s sponsored research agreement with Yonsei University offset by a decrease in consulting related expenses.

Selling, general and administrative expenses were $1.6 million for the third quarter of 2008 compared to $1.2 million for the same period last year.  The increase is primarily attributable to increased promotional and advertising activities in both the personalized health segment and the consumer products segment, in addition to increased compensation expenses due to increased headcount.

On September 30, 2008, the Company had cash and cash equivalents of $5.9 million compared to $7.6 million of cash and cash equivalents on December 31, 2007.  In addition, the Company has access to $10.3 million under credit facilities with Alticor, which permit borrowing until March 31, 2009.

Third Quarter and Recent Highlights

·Entered into a Research and License Agreement with Geisinger Health System:  In September 2008, Interleukin Genetics and Geisinger announced a collaboration permitting Interleukin Genetics to utilize Geisinger’s databases to develop a series of genetic tests that will help physicians better understand an individual’s inherited resistance to weight loss and gauge a patient’s likelihood of success with diet and other weight loss techniques.

·Revised Exclusive License Agreement with Alticor Corporation’s Access Business Group International, LLC (ABG):  In September 2008, Interleukin Genetics and ABG amended the companies’ existing agreement to expand Interleukin Genetics’ distribution network for genetic tests jointly developed by the two companies.  The revised agreement permits the Company to sell products through additional channels of its choosing.

·Licensed PST Genetic Test to OralDNA Labs, Inc.:  In August 2008, Interleukin Genetics announced a marketing, sales and distribution agreement for its proprietary PST genetic risk assessment test for use in the diagnosis of periodontal disease.  As compensation, the Company will receive a payment from OralDNA Labs for each product it sells, with minimum sales requirements.

·Won International Award for Outstanding Research Published in Journal, Nutrition:  In September 2008, the researchers at Interleukin Genetics received the 12^th John M. Kinney Award for Nutrition and Metabolism at the annual Congress of the European Society of Parenteral and Enteral Nutrition in Florence, Italy.  The award was given for the paper, “Interleukin-1 genotype-selective inhibition of inflammatory mediators by a botanical: a nutrigenetics proof of concept.”

·Presented findings at 2008 World Congress on Osteoarthritis:  In September 2008, Kenneth Kornman, Ph.D., the Company’s Chief Scientific Officer, presented important new research findings on the genetics of osteoarthritis (OA) in Rome, demonstrating that Interleukin Genetics’ genetic test appears to identify knee OA patients likely to develop more severe joint destruction as they age.

·Enhanced Heart Health Genetic Test Report Format:  In July 2008, the Company launched an enhanced test report format and information package for the Company’s Heart Health Genetic Test, currently marketed under the brand name Gensona® by Amway Global.  The new report includes quantified risk

information on heart attack and coronary artery disease generated from clinical studies and provides individuals and their physicians with more complete information about a person’s inflammation-based genetic risk for a heart attack, along with preventive measure guidance and scientific educational materials.

·Expanded Board of Directors:  In July 2008, the Company added three new directors to the Board: Mary E. Chowning, Glenn S. Armstrong, Ph.D., and Chief Executive Officer Lewis H. Bender.  Ms. Chowning also will serve as the Chairperson of the Audit Committee of the Board.
