  Reports Significant Revenue Increase over Previous Year and Strong
                             Cash Position

       Conference Call Scheduled for 4:30 PM EST - April 2, 2007


    WALTHAM, Mass.--(BUSINESS WIRE)--April 2, 2007--Interleukin
Genetics, Inc. (AMEX: ILI) today reported financial results for its
year-end 2006 and fourth quarter ended December 31, 2006.

    The Company reported revenues of $4.7 million and a net loss of
$6.9 million, or $(0.27) per basic and diluted common share, for the
year ended December 31, 2006 and revenues of $1.8 million and a net
loss of $2.6 million, or $(0.10) per basic and diluted common share,
for the quarter ended December 31, 2006. Interleukin Genetics'
reported revenues resulted from the processing of genetic assessment
tests launched in the first quarter of 2006 for cardiovascular health
risk and general nutrition, and from sales of nutritional supplement
products in food, drug, and mass retail outlets through its
subsidiary, the Alan James Group, since it was acquired in August of
2006.

    "Interleukin Genetics ended 2006 in a very strong operational and
financial position. With a global distribution partner for our genetic
risk assessment tests and brand-name distribution channels for our
nutritional supplement products business, we believe that we are well
positioned to capitalize on the promising future of personalized
health," said Tim Richerson, Interleukin Genetics' CEO. "Importantly,
we have the financial resources to execute on this vision. Looking
forward in 2007, we will be concentrating our efforts on expanding the
marketing tools and markets for our current products while advancing
the research and development of additional products for our portfolio
of wellness products."

    Operating highlights for 2006 included:

    --  Interleukin Genetics began operations in its specially
        designed and constructed genetic testing laboratory, certified
        under the Clinical Laboratory Improvement Amendments (CLIA),
        and processed first samples in February 2006.

    --  The Company commenced sales in March 2006, through its global
        distribution partner Alticor, of two new genetic risk
        assessment tests for personal wellness - the IL-1 test for
        cardiovascular health and the general nutrition test.

    --  Interleukin Genetics acquired the Alan James Group in August
        of 2006 to provide Interleukin with new products and sales and
        marketing leadership in the rapidly expanding consumer health
        segment.

    --  Concurrent with the Alan James Group acquisition, the Company
        secured $30.0 million in equity and debt financing through
        Alticor.

    --  The Company initiated a study with Catholic University Center
        for High Technology Research and Education in Biomedical
        Sciences in Campobasso, Italy to study the link between
        inflammation genetic tests and stroke affecting men and women
        at a young age. This study may support the development of new
        genetic tests that provide important information about common
        diseases.

    --  The Company initiated a new study in China utilizing its
        proprietary IL-1 technology to evaluate potential
        population-specific genetic links to myocardial infarction at
        an early age. The study has enrolled 1,100 patients to date
        and expects to enroll approximately 1,300 subjects. A similar
        study that is ongoing in Korea and is expected to meet its
        enrollment target of 750 subjects in the second quarter.

    --  The Company secured an exclusive license for weight management
        technology from GeneOb as a component in the development of a
        new genetic risk assessment test for weight management
        intended for future release.

    --  The Company entered into a one-year research agreement with
        Alticor to develop its technology in dermagenomics to develop
        personalized skin care products and to expand the development
        of other tests.

    Year End Results

    Revenue for the year ended December 31, 2006, was $4.7 million
compared to $23,000 in 2005. The increase was due to revenues of $2.7
million from the personalized health segment, including $2.6 million
from processing of genetic tests which were launched in the first
quarter of 2006 (specifically cardiovascular health and general
nutrition genetic tests) and $2.1 million from the consumer products
segment which sells branded nutritional supplements to large retail
outlets through the Alan James Group since August 17, 2006 (the date
of Interleukin's acquisition of that business).

    Research and development expenses were $3.3 million for the year
ended December 31, 2006, compared to $3.1 million for 2005.

    Selling, general and administrative expenses were $4.5 million for
the year ended December 31, 2006, compared to $2.9 million during
2005. This increase was primarily attributable to costs associated
with the operation of the Alan James Group.

    The Company reported a net loss of $6.9 million, or $(0.27) per
basic and diluted common share, for the year ended 2006 compared to a
net loss of $6.6 million, or $(0.28) per basic and diluted common
share in 2005.

    Fourth Quarter Results

    Revenue for the three months ended December 31, 2006, was $1.8
million compared to $2,000 for the same period in 2005. The increase
was due to revenues of $444,000 from its personalized health segment,
primarily from processing of genetic tests received from Alticor for
sales of the heart health and the general nutrition tests and $1.4
million from its consumer products segment which sells branded
nutritional supplements to large retail outlets through the Alan James
Group.

    Research and development expenses were $842,000 for the quarter
ended December 31, 2006, compared to $959,000 for the quarter ended
December 31, 2005. These research expenses were largely incurred in
support of funded research for our collaboration with Alticor.

    Selling, general and administrative expenses were $1.8 million for
the three months ended December 31, 2006, compared to $661,000 during
the same period in the prior year, an increase of approximately 173%.
This increase was primarily attributable to costs associated with the
operation of the Alan James Group.

    The Company reported a net loss of $2.6 million, or $(0.10) per
basic and diluted common share, for the fourth quarter of 2006
compared to a net loss of $1.8 million, or $(0.07) per basic and
diluted common share, for the fourth quarter of 2005.

    On December 31, 2006, the Company reported cash and cash
equivalents of $10.1 million compared to $3.4 million of cash and cash
equivalents on December 31, 2005. In addition, on December 31, 2006,
