PROXY STATEMENT FOR THE INTERLEUKIN GENETICS, INC.
2008 ANNUAL MEETING OF STOCKHOLDERS

GENERAL INFORMATION ABOUT THE ANNUAL MEETING

Why Did You Send Me this Proxy Statement?

        We sent you this proxy statement and the enclosed proxy card because our Board of Directors is soliciting your proxy to vote at the 2008 annual meeting of stockholders and any adjournments of the meeting. This proxy statement summarizes the information you need to know to vote at the annual meeting.

        On or about May 5, 2008, we began sending this proxy statement, the attached notice of annual meeting and the enclosed proxy card to all stockholders entitled to vote at the meeting. Although not part of this proxy statement, we are also sending, along with this proxy statement, our 2007 Annual Report, which includes our financial statements for the fiscal year ended December 31, 2007. You can also find a copy of our 2007 Annual Report on Form 10-K on the internet through the SEC's electronic data system called EDGAR at www.sec.gov or through the Investors Relations section of our website at www.ilgenetics.com.

Who Can Vote?

        Only stockholders who owned common stock or Series A Preferred Stock at the close of business on April 24, 2008 are entitled to vote at the annual meeting. On this record date, there were 30,833,811 shares of our common stock and 5,000,000 shares of our Series A Preferred Stock outstanding.

        You do not need to attend the annual meeting to vote your shares. Shares represented by valid proxies, received in time for the meeting and not revoked prior to the meeting, will be voted at the meeting. A stockholder may revoke a proxy before the proxy is voted by delivering to our Secretary a signed statement of revocation or a duly executed proxy card bearing a later date. Any stockholder who has executed a proxy card but attends the meeting in person may revoke the proxy and vote at the meeting.

How Many Votes Do I Have?

        Each share of our common stock that you own entitles you to one vote. On the record date, there were a total of 30,833,811 shares of common stock outstanding. Each share of our Series A Preferred Stock entitles the holder to approximately 5.63 votes. On the record date there were 5,000,000 shares of Series A Preferred Stock outstanding, entitling the holder of those shares to an aggregate of 28,160,200 votes.

How Do I Vote?

        Whether you plan to attend the annual meeting or not, we urge you to vote by proxy. Voting by proxy will not affect your right to attend the annual meeting. If your shares are registered directly in

1



your name through our stock transfer agent, Computershare Trust Company, N.A., or you have stock certificates, you may vote:

        If your shares are held in "street name" (held in the name of a bank, broker or other nominee), you must provide the bank, broker or other nominee with instructions on how to vote your shares and can do so as follows:

How Does the Board of Directors Recommend That I Vote on the Proposals?

        The Board of Directors recommends that you vote as follows:

        If any other matter is presented at the annual meeting, the proxy card provides that your shares will be voted by the proxy holder listed on the proxy card in accordance with his or her best judgment. At the time this proxy statement was printed, we knew of no matters being presenated at the annual meeting, other than those discussed in this proxy statement.

May I Revoke My Proxy?

        If you give us your proxy, you may revoke it at any time before it is exercised. You may revoke your proxy in any one of the following ways:

What if I Receive More Than One Proxy Card?

        You may receive more than one proxy card or voting instruction form if you hold shares of our common stock in more than one account, which may be in registered form or held in street name.

2



Please vote in the manner described under "How Do I Vote?" for each account to ensure that all of your shares are voted.

Will My Shares be Voted if I Do Not Return My Proxy Card?

        If your shares are registered in your name or if you have stock certificates, they will not be voted if you do not return your proxy card by mail or vote at the meeting as described above under "How Do I Vote?" If your shares are held in street name and you do not provide voting instructions to the bank, broker or other nominee that holds your shares as described above under "How Do I Vote?," the bank, broker or other nominee has the authority to vote your unvoted shares on Proposal 1 even if it does not receive instructions from you. We encourage you to provide voting instructions. This ensures your shares will be voted at the meeting in the manner you desire. If your broker cannot vote your shares on a particular matter because it has not received instructions from you and does not have discretionary voting authority on that matter or because your broker chooses not to vote on a matter for which it does have discretionary voting authority, this is referred to as a "broker non-vote."

What Vote is Required to Approve the Proposal and How are Votes Counted?

Proposal 1: Ratify Appointment of Our Independent Public Accountants   The affirmative vote of a majority of the votes present or represented by proxy and entitled to vote at the annual meeting is required to ratify the appointment of our independent public accountants. Abstentions will be treated as votes against this proposal. Brokerage firms have authority to vote customers' unvoted shares held by the firms in street name on this proposal. If a broker does not exercise this authority, such broker non-votes will have no effect on the results of this vote. We are not required to obtain the approval of our stockholders to select our independent accountants. However, if our stockholders do not ratify the appointment of Grant Thornton LLP as our independent accountants for 2008, our Audit Committee of the Board of Directors will reconsider its selection.

Is Voting Confidential?

        We will keep all the proxies, ballots and voting tabulations private. We will only let our Inspector of Elections, Computershare Trust Company, N.A., examine these documents. We will not disclose your vote to management unless it is necessary to meet legal requirements. We will, however, forward to management any written comments you make, on the proxy card or elsewhere.

What Are the Costs of Soliciting these Proxies?

        We will pay all of the costs of soliciting these proxies. We plan to retain Broadridge Financial Services, Inc. (formerly ADP Investor Communication Services) to assist in the distribution of proxies and accompanying materials to brokerage houses and institutions for an estimated fee of $10,000 plus expenses. In addition, our directors and employees may solicit proxies in person or by telephone, fax or email. We will pay these employees and directors no additional compensation for these services. We will ask banks, brokers and other institutions, nominees and fiduciaries to forward these proxy materials to their principals and to obtain authority to execute proxies. We will then reimburse them for their expenses.

3


What Constitutes a Quorum for the Meeting?

        The presence, in person or by proxy, of the holders of a majority of the outstanding shares of our common stock and our Series A Preferred Stock on an as-converted to common stock basis constitutes a quorum for this meeting. Votes of stockholders of record who are present at the meeting in person or by proxy, abstentions, and broker non-votes are counted for purposes of determining whether a quorum exists.

Attending the Annual Meeting

        The annual meeting will be held at 10:00 a.m. on Thursday, June 12, 2008 at the offices of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., our legal counsel, located at The Chrysler Center, 666 Third Avenue, New York, NY 10017. When you arrive at the meeting signs will direct you to the appropriate meeting rooms. You need not attend the annual meeting in order to vote. Instead, you may vote your shares by marking, signing, dating and returning the enclosed proxy card.

Householding of Annual Disclosure Documents

        In December 2000, the Securities and Exchange Commission adopted a rule concerning the delivery of annual disclosure documents. The rule allows us or your broker to send a single set of our annual report and proxy statement to any household at which two or more of our stockholders reside, if we or your broker believe that the stockholders are members of the same family. The rule applies to our annual reports, proxy statements and information statements. We do not engage in this practice, referred to as "householding," however your broker or other nominee may. Once you receive notice from your broker that communications to your address will be "householded," the practice will continue until you are otherwise notified or until you revoke your consent to the practice. Each stockholder will continue to receive a separate proxy card or voting instruction card.

        If your household received a single set of disclosure documents this year, but you would prefer to receive your own copy, please contact our transfer agent, Computershare Trust Company, N.A., by calling them at 1-800-962-4284.

        If you do not wish to participate in "householding" and would like to receive your own set of our annual disclosure documents in future years, follow the instructions described below. Conversely, if you share an address with another one of our shareholders and together both of you would like to receive only a single set of our annual disclosure documents, follow these instructions:

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

        The following table sets forth certain information with respect to the beneficial ownership of our common stock as of March 31, 2008 for (a) the executive officers named in the Summary Compensation Table of this proxy statement, (b) each of our directors and director nominees, (c) all of our current directors and executive officers as a group and (d) each stockholder known to us to beneficially own more than five percent of our common stock. Beneficial ownership is determined in accordance with the rules of the SEC and includes voting or investment power with respect to the securities. We deem shares of common stock that may be acquired by an individual or group within 60 days following March 31, 2008 pursuant to the exercise of options or warrants to be outstanding for the purpose of computing the percentage ownership of such individual or group, but are not deemed to be outstanding for the purpose of computing the percentage ownership of any other person shown in the table. Except as otherwise indicated, we believe that the stockholders named in the table have sole voting and investment power with respect to all shares of common stock shown to be beneficially owned by them based on information provided to us by these stockholders. Percentage ownership is based on a total of 30,833,811 shares of common stock issued and outstanding on March 31, 2008.

CORPORATION GOVERNANCE MATTERS

Director Independence

        Our Board of Directors has determined that the following members qualify as independent directors under the definition promulgated by the American Stock Exchange and the Boston Stock Exchange: James W. Weaver, George D. Calvert, Thomas R. Curran, Jr. and Dianne E. Bennett.

Committees of the Board of Directors and Meetings

        Our Board of Directors has established five standing committees, Audit, Compensation, Nominating, Strategic Planning and Operations, each as described below.

        Meeting Attendance.    During the fiscal year ended December 31, 2007, the Board of Directors met five times. Each of our Directors attended at least 75% of the aggregate of the meetings of the Board of Directors and committees of which they are a member. The Board of Directors has adopted a policy under which each member is encouraged to make every reasonable effort to attend each annual meeting of our stockholders. Two of the directors attended our 2007 annual meeting of stockholders.

        Audit Committee.    Our Audit Committee met seven times during the fiscal year ended December 31, 2007. This committee currently consists of Dianne E. Bennett (Chairperson), George D. Calvert and James M. Weaver. Our Audit Committee is responsible for retaining and overseeing our independent accountants, approving the services performed by them and reviewing our annual financial statements, accounting policies and our system of internal controls. All members of the Audit Committee satisfy the current independence standards promulgated by the Securities and Exchange Commission, the American Stock Exchange and the Boston Stock Exchange, as such standards apply specifically to members of audit committees. The Board of Directors has determined that Ms. Bennett and Mr. Weaver are each "audit committee financial experts" as the Securities and Exchange Commission has defined that term in Item 407 of Regulation S-K. Please also see the Audit Committee Report set forth elsewhere in this proxy statement.

        A copy of the Audit Committee's written charter is publicly available on our website at www.ilgenetics.com.

        Compensation Committee.    Our Compensation Committee met once during the fiscal year ended December 31, 2007. The Compensation Committee currently consists of George D. Calvert (Chairman), James M. Weaver and Dianne E. Bennett. Our Compensation Committee reviews our compensation philosophy and programs, exercises authority with respect to the payment of salaries and incentive compensation to our directors and officers and makes recommendations to the Board of Directors regarding stock option grants under our 2000 Employee Stock Compensation Plan and 2004 Directors, Officers and Employees Stock Compensation Plan. The Compensation Committee is responsible for the determination of the compensation of our Chief Executive Officer, and conducts its decision making process with respect to that issue without the Chief Executive Officer present. All members of the Compensation Committee qualify as independent under the definitions promulgated by the American Stock Exchange and the Boston Stock Exchange. To date, the Compensation Committee has not adopted a written charter.

        Nominating Committee.    Our Nominating Committee met once during fiscal 2007. The Nominating Committee currently consists of James M. Weaver (Chairman), George D. Calvert and Dianne E. Bennett. All members of the Nominating Committee qualify as independent under the definition promulgated by the American Stock Exchange and the Boston Stock Exchange. This committee's role is to make recommendations to the Board of Directors as to the size and composition of the Board of Directors and to make recommendations as to particular nominees. The Nominating Committee may consider candidates recommended by stockholders as well as from other sources such as other directors

9



or officers, third party search firms or other appropriate sources. For all potential candidates, the Nominating Committee may consider all factors it deems relevant, such as a candidate's personal integrity and sound judgment, business and professional skills and experience, independence, knowledge of the industry in which we operate, possible conflicts of interest, diversity, the extent to which the candidate would fill a present need on the Board of Directors, and concern for the long-term interests of the stockholders. In general, persons recommended by stockholders will be considered on the same basis as candidates from other sources. If a stockholder wishes to nominate a candidate to be considered for election as a director at the 2009 Annual Meeting of Stockholders using the procedures set forth in the Company's By-laws, it must follow the procedures described in "Stockholder Proposals and Nominations For Director" of this proxy statement. If a stockholder wishes simply to propose a candidate for consideration as a nominee by the Nominating Committee, it should submit any pertinent information regarding the candidate to the Chairman of the Nominating Committee by mail at Secretary, Interleukin Genetics, Inc., 135 Beaver Street, Waltham, Massachusetts 02452.

        A copy of the Nominating Committee's written charter is publicly available on our website at www.ilgenetics.com.

Compensation Committee Interlocks and Insider Participation

        The Compensation Committee consists of three members, George D. Calvert (Chairman), James M. Weaver and Dianne E. Bennett. None of our executive officers serve on the Board of Directors or Compensation Committee of any entity that has one or more executive officers serving as a member of the Board of Directors or Compensation Committee. There is no family relationship between or among the directors (including the Series A Directors) and executive officers.

Shareholder Communications to the Board

        Generally, shareholders who have questions or concerns regarding us should contact the Company at (781) 398-0700. However, any shareholders who wish to address questions regarding our business directly with the Board of Directors, or any individual director, should direct his or her questions in writing to the Chairman of the Board at Interleukin Genetics, Inc., 135 Beaver Street, Waltham, Massachusetts 02452. Communications will be distributed to the Board, or to any individual director or directors as appropriate, depending on the facts and circumstances outlined in the communications. Items that are unrelated to the duties and responsibilities of the Board may be excluded, such as:


In addition, any material that is unduly hostile, threatening, or illegal in nature may be excluded, provided that any communication that is filtered out will be made available to any outside director upon request.

Corporate Opportunity Agreement

        We have agreed to certain terms for allocating opportunities as permitted under Section 122(17) of the Delaware General Corporation Law. This agreement, as set forth in the Series A Preferred Stock Purchase Agreement dated March 5, 2003, regulates and defines the conduct of certain of our affairs as they may involve Pyxis Innovations Inc. as our majority stockholder and its affiliates, and the powers, rights, duties and liabilities of us and our officers and directors in connection with corporate opportunities.

10


        Except under certain circumstances, Pyxis and its affiliates have the right to engage in the same or similar activities or lines of business or have an interest in the same classes or categories of corporate opportunities as we do. If Pyxis, or one of our directors appointed by Pyxis, and its affiliates acquire knowledge of a potential transaction or matter that may be a corporate opportunity for both Pyxis and its affiliates and us, to the fullest extent permitted by law, Pyxis and its affiliates will not have a duty to inform us about the corporate opportunity or be liable to us or to you for breach of any fiduciary duty as a stockholder of ours for not informing us of the corporate opportunity, keeping it for its own account, or referring it to another person.

        Additionally, except under limited circumstances, if an officer or employee of Pyxis who is also one of our directors is offered a corporate opportunity, such opportunity shall not belong to us. In addition, we agreed that such director will have satisfied his duties to us and not be liable to us or to you in connection with such opportunity.

        The terms of this agreement will terminate on the date that no person who is a director, officer or employee of ours is also a director, officer, or employee of Pyxis.

The material terms of these executives' (all former, except Dr. Kornman) employment agreements are described below. The descriptions aid in the understanding and interpretation of certain data found in the tables contained in this Executive Compensation section.

Timothy J. Richerson

        On August 17, 2006, we entered into a three-year employment agreement with Timothy J. Richerson, our Chief Executive Officer, which provides for a minimum annual base salary of $300,000, an immediate grant of 12,500 fully-vested shares of our common stock, annual grants of an additional 12,500 fully-vested shares of our common stock, annual discretionary bonuses of up to 40% of base salary and a $600 per month automobile allowance. This employment agreement is terminable by Mr. Richerson upon one month prior written notice and by us for cause. The agreement also provides that if he is terminated without cause or he terminates his employment for good reason, he shall have the right to receive severance benefits in the amount of his then current base salary and health insurance benefits until the earlier to occur of the expiration of the term of the agreement or eighteen months following the date of termination. In the event of a change of control, all unvested shares of our common stock held by Mr. Richerson would automatically vest. In addition, the agreement provides that he will be prohibited, for a period of twelve months following the date of termination of the employment agreement, from accepting employment, or otherwise becoming involved, in any manner, with one of our direct competitors, or from providing services to any person or entity that might conflict with our interests or the interests of our customers or clients.

On March 25, 2008, we entered into an agreement with Messrs. Richerson and Finkelstein, pursuant to which we agreed to pay them an aggregate of $1.2 million. In the case of Mr. Richerson, we also agreed to limit the duration of his non-competition restrictions to July 31, 2009. Messrs. Richerson and Finkelstein agreed that no further amounts are or will become due under their employment agreements.

Kenneth Kornman, DDS, Ph.D.

        On March 30, 2006, we entered into an Employment Agreement with our President, Chief Executive Officer, and Chief Scientific Officer, Kenneth S. Kornman. Under the Agreement, Dr. Kornman will be employed for a period of three years, will receive a base salary at an annual rate of $340,000 and will be eligible to receive annual bonuses solely at the discretion of the Board of Directors. While Dr. Kornman remains employed by us, he will receive a grant of 12,500 shares of our common stock on the first three anniversaries of March 30, 2006.

        If Dr. Kornman is terminated by us without Cause (as defined in the Agreement), Dr. Kornman terminates his employment with us for Good Reason (as defined in the Agreement), or the term of the Agreement expires, then Dr. Kornman shall be permitted to exercise any then-outstanding stock options for a period of up to two years from such termination.

This employment agreement is terminable by Mr. Finkelstein upon one month prior written notice and by us for cause. The agreement also provides that if he is terminated without cause or he terminates his employment for good reason, he shall have the right to receive severance benefits in the amount of his then current base salary and health insurance benefits until the earlier to occur of the expiration of the term of the agreement or twelve months following the date of termination.

In addition, the agreement provides that he will be prohibited, for a period of twelve months following the date of termination of the employment agreement, from accepting employment, or otherwise becoming involved, in any manner, with one of our direct competitors, or from providing services to any person or entity that might conflict with our interests or the interests of our customers or clients.

Summary Description of the Company's Non-Stockholder Approved Equity Compensation Plans

        On June 1, 1999, we entered into a Non-Qualified Stock Option Agreement with Philip R. Reilly to induce him to enter a consulting services agreement dated the same day and to encourage him to become our Chairman of the Board of Directors. Pursuant to the Agreement, we granted Mr. Reilly the option to purchase 240,000 shares of our common stock at $.50 per share on or before the option's expiration date of June 1, 2009. These options vested in equal increments of 8,000 shares per month over thirty months and became fully vested on December 1, 2001. Mr. Reilly has exercised this option with respect to all 240,000 shares of common stock. The options are non-transferable.

        On November 30, 1999, we entered into an additional Non-Qualified Stock Option Agreement with Philip R. Reilly to further induce him to become our Chairman of the Board of Directors. Pursuant to the Agreement, we granted Mr. Reilly the option to purchase 351,394 shares of our common stock at $2.875 per share on or before the option's expiration date of December 31, 2010. These options vested in equal increments of 9,760 shares per month over a period of thirty-six months and became fully vested on November 30, 2002. The options are non-transferable.

        Effective on July 1, 1999, we entered into a five-year Research and Technology Transfer Agreement with the University of Sheffield. The agreement provided for the grant of options to purchase 100,000 shares of our common stock. Pursuant to the agreement, we were required to grant options to purchase 25,000 shares annually at the beginning of each year of the last four years of the five-year arrangement. The options were granted with an exercise price equal to the current market price of the common stock at the time of grant, each June 30th, of the five-year arrangement. The options are fully vested when granted and exercisable for a period of five years from each date of grant. The agreement further provided that the University of Sheffield was to receive additional options to purchase 10,000 shares of stock at the current market price each June 30th for each patent that was filed on our behalf during the previous twelve months. As of the date of this report options to purchase 150,000 shares have been granted under this agreement.

        Concurrent with the execution of the Research and Technology Transfer Agreement with the University of Sheffield, we entered into a five-year Consulting Services Agreement with the university's key collaborator, Gordon W. Duff. The agreement provided for the grant of options to purchase up to a total of 100,000 shares of our common stock. Pursuant to the agreement, we were required to grant options to purchase 25,000 shares annually at the beginning of each year of the last four years of the five-year arrangement. The options were granted with an exercise price equal to the current market price of the common stock at the time of grant, each June 30th, of the five-year arrangement. The options are fully vested when granted and exercisable for a period of five years from each date of grant. As of the date of this report, all 100,000 options have been granted under this agreement.

Director Compensation

        Our policy is to pay each non-employee member of our Board of Directors $1,000 in cash compensation for each meeting of the Board of Directors attended in person by that director and 15,000 stock options to vest on the first anniversary of the grant date. Each of the current non-employee members of our Board of Directors declined such compensation for 2007 and thus we did not pay them for their Board service.

AUDIT COMMITTEE REPORT

        The Audit Committee of the Board of Directors, which is consists entirely of directors who meet the independence and experience requirements of the American Stock Exchange, on which the company's shares are listed, has furnished the following report.

        The Audit Committee assists the Board in overseeing and monitoring the integrity of our financial reporting process, compliance with legal and regulatory requirements and the quality of internal and external audit processes. The committee's role and responsibilities are set forth in our charter adopted by the Board, which is available on our website at www.igenetics.com. This committee reviews and reassesses our charter annually and recommends any changes to the Board for approval. The Audit Committee is responsible for overseeing our overall financial reporting process, and for the appointment, compensation, retention, and oversight of the work of Grant Thornton, LLP, or independent auditors. In fulfilling its responsibilities for the financial statements for the fiscal year ended December 31, 2007, the Audit Committee took the following actions:

        Based on the Audit Committee's review of the audited financial statements and discussions with management and Grant Thornton LLP, the Audit Committee recommended to the Board that the audited financial statements be included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2007 for filing with the SEC.


COMPLIANCE WITH SECTION 16(A) OF THE SECURITIES EXCHANGE ACT OF 1934

        Our records reflect that all reports which were required to be filed pursuant to Section 16(a) of the Exchange Act were filed on a timely basis.


CODE OF CONDUCT AND ETHICS

        We have adopted a code of conduct and ethics that applies to all of our employees, including our chief executive officer and chief financial and accounting officers. The text of the code of conduct and ethics will be made available to stockholders without charge, upon request in writing to the Corporate Secretary at Secretary, Interleukin Genetics, Inc., 135 Beaver Street, Waltham, Massachusetts 02452. Disclosure regarding any amendments to, or waivers from, provisions of the code of conduct and ethics that apply to our directors, principal executive and financial officers will be included in a Current Report on Form 8-K within five business days following the date of the amendment or waiver.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

        Pursuant to the written charter of our Audit Committee, the Audit Committee is responsible for reviewing and approving, prior to our entry into any such transaction, all transactions in which we are a participant and in which any of the following persons has or will have a direct or indirect material interest: our executive officers; our directors; the beneficial owners of more than 5% of our securities; the immediate family members of any of the foregoing persons; and any other persons whom the Board determines may be considered related persons, any such person being referred to as a "related person."

        The following is a description of arrangements that we have entered into with related persons during the fiscal year ended December 31, 2007 and were approved by our Audit Committee. We believe that the transactions described below were made on terms no less favorable to us than could have been obtained from unaffiliated third parties.

        In March 2007, we entered into a new research agreement with Access Business Group International LLC, a subsidiary of Alticor Inc. and an affiliate of our primary stockholder, Pyxis Innovations Inc. The research agreement encompasses the development of genetic tests to guide consumers' selection of appropriate skin care products; the further development of tests for weight management and the risk of osteoporosis, as well as the development of other tests. Under the terms of the agreement, we are eligible to receive up to $2.3 million in additional research funding during 2007.

        In December 2007, we entered into an agreement with Alticor Inc., effective as of July 3, 2007, with respect to the services of Mr. Curran. Pursuant to the terms of the agreement, and in exchange for Mr. Curran's services as our Interim Chief Executive Officer during the term of the agreement, we agreed to pay directly to Alticor $30,000 per month. We agreed to reimburse Mr. Curran directly for travel and other incidental expenses incurred in the performance of his services for us. Either we or Alticor may terminate the agreement at any time by providing fifteen days advance written notice to the other party.

        In October 2002, we issued to Pyxis Innovations Inc. certain promissory notes under a note purchase agreement, as subsequently amended. In December 2007, Pyxis converted the certain of the notes due on December 31, 2007, representing an aggregate principal amount of $2,000,000 and accrued interest of $39,679.43, into 3,190,987 shares of our common stock. These shares are subject to the registration rights agreement, dated March 5, 2003, between us and Pyxis.


ANNUAL REPORT ON FORM 10-K; INCORPORATION BY REFERENCE

        Upon the written request of any record holder or beneficial owner of common stock entitled to vote at the Annual Meeting, we will provide, without charge, a copy of our Annual Report on Form 10-K for the year ended December 31, 2007, as filed with the SEC on March 31, 2008. Requests should be directed to Investor Relations, Interleukin Genetics, Inc., 135 Beaver Street, Waltham, Massachusetts 02452.

        To the extent this proxy statement has been or will be specifically incorporated by reference into any filing by Interleukin under the Securities Act of 1933, as amended, or the Exchange Act, the section of this proxy statement entitled "Audit Committee Report" shall not be deemed to be so incorporated unless specifically otherwise provided in any such filing.

PROPOSAL 1:
RATIFY APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANTS

        Our Audit Committee has appointed Grant Thornton LLP, independent public accountants, to audit our financial statements for the fiscal year ending December 31, 2008. The Board proposes that the stockholders ratify this appointment. Grant Thornton LLP audited our financial statements for the fiscal years ended December 31, 2007, 2006 and 2005. We expect that representatives of Grant Thornton LLP will be present at the meeting, will be able to make a statement if they so desire, and will be available to respond to appropriate questions.

Policy on Audit Committee Pre-Approval of Audit and Permissible Non-audit Services of Independent Auditors

        Consistent with SEC policies regarding auditor independence, the Audit Committee has responsibility for appointing, setting compensation and overseeing the work of the independent auditor. In recognition of this responsibility, the Audit Committee has established a policy to pre-approve all audit and permissible non-audit services provided by the independent auditor.

        Prior to the engagement of the independent auditor for the next year's audit, management will submit to the Audit Committee for approval a summary of the services expected to be rendered during that year for each of four categories of services.

        1.     Audit services include audit work performed in the preparation of financial statements, as well as work that generally only the independent auditor can reasonably be expected to provide, including comfort letters, statutory audits, and attest services and consultation regarding financial accounting and/or reporting standards.

        2.     Audit-Related services are for assurance and related services that are traditionally performed by the independent auditor, including due diligence related to mergers and acquisitions, employee benefit plan audits, and special procedures required to meet certain regulatory requirements.

        3.     Tax services include all services performed by the independent auditor's tax personnel except those services specifically related to the audit of the financial statements, and includes fees in the areas of tax compliance, tax planning, and tax advice.

19


        4.     Other Fees are those associated with services not captured in the other categories. The Company generally does not request such services from the independent auditor.

        Prior to the engagement, the Audit Committee pre-approves these services by category of service. The fees are budgeted and the Audit Committee requires the independent auditor and management to report actual fees versus the budget periodically throughout the year by category of service. During the year, circumstances may arise when it may become necessary to engage the independent auditor for additional services not contemplated in the original pre-approval. In those instances, the Audit Committee requires specific pre-approval before engaging the independent auditor.

        The Audit Committee may delegate pre-approval authority to one or more of its members. The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next scheduled meeting.

        The affirmative vote of a majority of the shares present or represented and entitled to vote at the Meeting, voting together on an as-converted basis, is required to ratify the appointment of the independent public accountants.

        In the event the stockholders do not ratify the appointment of Grant Thornton LLP as our independent public accountants, the Audit Committee will reconsider its appointment.

The Board of Directors recommends a vote "FOR" to ratify the appointment of Grant Thornton LLP
as independent public accountants, and proxies solicited by the Board will be voted in
favor of such ratification unless a stockholder indicates otherwise on the proxy.
