INTERLEUKIN GENETICS REPORTS FIRST QUARTER 2008 FINANCIAL RESULTS

WALTHAM, MA – May 14, 2008 - Interleukin Genetics, Inc. (AMEX: ILI) today announced financial and business results for the first quarter ended March 31, 2008.

The Company reported a net loss of $1.9 million, or $(0.06) per basic and diluted common share, for the first quarter of 2008 compared to a net loss of $1.7 million, or $(0.06) per basic and diluted common share, for the same period last year.

Revenue for the first quarter of 2008 was $2.7 million compared to $2.4 million for the same period last year. The increase in revenue is primarily attributable to an increase in consumer product sales.

“We got off to a strong start in 2008 with the expansion of our agreement with Alticor for genetic tests in new and important disease areas and with the peer-reviewed publication in Human Genetics of additional supportive information on the relationship between IL-1 and inflammatory disease. In addition, we expanded our experienced management team, including our new CFO, to continue to further accelerate the development and commercialization of our genetic tests and other products,” commented Lewis H. Bender, Chief Executive Officer. “In the coming months, we expect to initiate new clinical studies for a number of programs and to re-invigorate our Heart Health product with a significantly improved communication package so that patients and their doctors can better understand the implications of the results and the recommended actions.”

Research and development expenses were $813,000 for the first quarter of 2008 compared to $674,000 for the same period last year. The increase is primarily attributable to the result of milestone payments under a sponsored research agreement.

Selling, general and administrative expenses were $2.1 million for the first quarter of 2008 compared to $1.7 million for the same period last year. The increase is primarily attributable to advertising costs as well as legal expenses associated with the settlement with the former owners of the Alan James Group.

On March 31, 2008, the Company reported cash and cash equivalents of $4.5 million compared to $7.6 million of cash and cash equivalents on December 31, 2007. In addition, the Company has access to $14.3 million under credit facilities with Alticor through August 2008.

First Quarter and Recent Highlights

Publication in Human Genetics Supporting Gensona® Heart Health Test: In May 2008, an article titled, “IL1B Gene Promoter Haplotype Pairs Predict Clinical Levels of Interleukin-1β and C-reactive Protein,” was published in the journal Human Genetics, further confirming prior studies associating variations in the Interleukin 1B (IL1B) gene with the inflammatory response.
New and Expanded Research Collaboration with Alticor: In February 2008, Interleukin Genetics and Alticor (a majority shareholder) announced a new research agreement with Access Business Group International LLC (ABG), a subsidiary of Alticor, Inc., for Interleukin Genetics to conduct studies in the areas of osteoporosis, cardiovascular disease, nutrigenomics and dermagenomics. ABG is expected to pay Interleukin Genetics $1.2 million during 2008 to fund the research. Approximately $800,000 of unspent funding from prior research agreements with Alticor will also be credited against the costs incurred under this new agreement.
Expanded Management Team: In April 2008, Interleukin Genetics appointed Eliot M. Lurier, CPA, as its Chief Financial Officer. Mr. Lurier has more than 25 years of financial management experience, primarily in the life sciences industry and was previously Vice President, Finance and Administration and Chief Financial Officer of Nucryst Pharmaceuticals. In January 2008, Interleukin appointed Lewis H. Bender as Chief Executive Officer and to its Board of Directors. Mr. Bender has over 15 years of biotechnology industry experience and held several senior executive positions, most recently as interim CEO of Emisphere.
