                        Second Quarter Financial Results;
          Conference Call Scheduled for 8:30 AM EDT - August 10, 2006


    WALTHAM, Mass.--(BUSINESS WIRE)--Aug. 9, 2006--Interleukin
Genetics, Inc. (AMEX: ILI) today reported financial results for the
second quarter and six months ended June 30, 2006. The Company
generated revenue of $1.3 million in the second quarter of 2006 and a
net loss of $923,000, or $(0.04) per basic and diluted common share,
for the quarter. Interleukin Genetics' reported revenues resulted
almost entirely from the processing of genetic assessment tests for
cardiovascular health and general nutrition.
    "These strong revenue results for the quarter have validated the
consumer interest in predictive genetic tests that are based on strong
science," said Ken Kornman, Interleukin Genetics' CEO. "Interleukin
has established a solid foundation on which to build our DNA
laboratory business with this first major launch of genetic tests
through our strategic partner, Alticor. We can now focus our efforts
on expanding our product pipeline, preparing for additional product
launches, and developing opportunities to further commercialize our
technology."

    Operating Highlights for the quarter ended June 30, 2006 included:

    --  The Company reported its first full quarter of revenues from
        two new genetic assessment tests.

    --  The Company expanded and upgraded its DNA analysis laboratory
        operation by adding equipment and staff to increase its
        throughput capabilities.

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

    --  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 and stroke affecting men and women at a young age
        using Interleukin's genetic tests. This study may support the
        development of new genetic tests that provide important
        information about common diseases.

    Revenue for the three months ended June 30, 2006 was $1.3 million
compared to $8,000 in the same period of 2005. The increase was
largely due to the revenues received from processing the
cardiovascular health and general nutrition genetic assessment tests,
both launched in the first quarter of 2006. While Interleukin
anticipates variability of sales due to the inherent uncertainty in
the introduction of new technology, the Company is providing guidance
for fiscal year 2006 annual revenues from genetic testing between $3
to $4 million.
    Cost of revenue, which includes fixed overhead costs associated
with laboratory operations, was $408,000 for the three months ended
June 30, 2006, resulting in a gross profit of $936,000, or 70% of
revenue. This gross margin was a result, in part, of one-time supplier
discounts and complimentary support from suppliers received by the
Company during its initial launch phase. For fiscal year 2006, the
Company expects its gross profit margin to be between 45% and 50% from
these genetic tests.
    Research and development expenses were $839,000 for the quarter
ended June 30, 2006 compared to $609,000 for the quarter ended June
30, 2005, an increase of approximately 38%. This increase is due to
research and development expenses funded by Alticor under agreements
for the development of new genetic tests, as well as expenses related
to the recording of $73,000 for stock-based compensation expense as a
result of new accounting rules.
    General and administrative expenses were $882,000 for the three
months ended June 30, 2006 compared to $1,064,000 during the same
period in the prior year, a decrease of approximately 17%. This
decrease was primarily attributable to the reduction of non-recurring
professional fees incurred by the company in 2006 compared to expenses
incurred in 2005 that were associated with the implementation of
Sarbanes-Oxley Section 404, partially offset by the recording of
$134,000 for stock-based compensation expense as a result of new
accounting rules.
    The Company reported a net loss of $923,000, or $(0.04) per basic
and diluted common share, for the second quarter of 2006 compared to a
net loss of $1.8 million, or $(0.08) per basic and diluted common
share, for the second quarter of 2005.
    On June 30, 2006, the Company reported cash and cash equivalents
of $2.4 million compared to $3.4 million of cash and cash equivalents
on December 31, 2005. In addition, on June 30, 2006, the Company had
access to $3.5 million under credit facilities with Alticor.
