Dear Stockholder:

We cordially invite you to attend our 2016 annual meeting of stockholders to be held at 10:00 a.m. on Thursday, October 20, 2016 at the offices of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., our legal counsel, located at One Financial Center, Boston, Massachusetts 02111. The attached notice of annual meeting and proxy statement describe the business we will conduct at the meeting and provide information about Interleukin Genetics, Inc. that you should consider when you vote your shares.

At the annual meeting, two persons will be elected to our Board of Directors. In addition, we will ask stockholders to ratify the selection of Grant Thornton LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2016; to consider an advisory vote on compensation of our named executive officers, as disclosed in this proxy statement; to approve an amendment to our Restated Certificate of Incorporation, to increase the number of authorized shares of common stock from 450,000,000 to 650,000,000 at any time prior to the earlier of (i) October 1, 2017 and (ii) the 2017 annual meeting of stockholders; to approve an amendment to our Restated Certificate of Incorporation, to effect a reverse stock split by combining outstanding shares of our common stock into a lesser number of outstanding shares by a ratio of not less than 1-for-15 and not more than 1-for-60 at any time prior to the earlier of (i) October 1, 2017 and (ii) the 2017 annual meeting of stockholders, with the exact ratio to be set within this range by our board of directors in its sole discretion; and to transact such other business as may properly come before the annual meeting.

Under Securities and Exchange Commission rules that allow companies to furnish proxy materials to shareholders over the Internet, we have elected to deliver our proxy materials to the majority of our shareholders over the Internet. This delivery process allows us to provide shareholders with the information they need, while at the same time conserving natural resources and lowering the cost of delivery. On September 9, 2016, we mailed to our shareholders a Notice of Internet Availability of Proxy Materials (the “Notice”) containing instructions on how to access our proxy statement for our 2016 Annual Meeting of Shareholders and our annual report to shareholders. The Notice also provides instructions on how to vote online or by telephone and includes instructions on how to receive a paper copy of the proxy materials by mail.

We hope you will be able to attend the annual meeting. Whether you plan to attend the annual meeting or not, it is important that you cast your vote. When you have finished reading the proxy statement, you are urged to vote in accordance with the instructions set forth in this proxy statement.

PROXY STATEMENT FOR THE INTERLEUKIN GENETICS, INC.
2016 ANNUAL MEETING OF STOCKHOLDERS

This proxy statement, along with the accompanying notice of 2016 annual meeting of stockholders, contains information about the 2016 annual meeting of stockholders of Interleukin Genetics, Inc., including any adjournments or postponements of the annual meeting. We are holding the annual meeting at 10:00 a.m. on Thursday, October 20, 2016 at the offices of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., our legal counsel, located at One Financial Center, Boston, Massachusetts 02111. In this proxy statement, we refer to Interleukin Genetics, Inc. as “Interleukin,” “the Company,” “we” and “us.”

This proxy statement relates to the solicitation of proxies by our Board of Directors for use at the annual meeting.

On or about September 9, 2016, we began sending the Important Notice Regarding the Availability of Proxy Materials (the “Notice”) to all stockholders entitled to vote at the annual meeting.

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF
PROXY MATERIALS FOR THE SHAREHOLDER MEETING

This proxy statement and our 2016 annual report to stockholders are available for viewing, printing and downloading at www.proxyvote.com. To view these materials please have your 16-digit control number(s) available that appears on your Notice or proxy card. On this website, you can also elect to receive future distributions of our proxy statements and annual reports to stockholders by electronic delivery.

Additionally, you can find a copy of our Annual Report on Form 10-K, which includes our financial statements, for the fiscal year ended December 31, 2015 on the website of the Securities and Exchange Commission, or the SEC, at www.sec.gov, or in the “SEC Filings” section of the “Investors” section of our website at www.ilgenetics.com. You may also obtain a printed copy of our Annual Report on Form 10-K, including our financial statements, free of charge, from us by sending a written request to: Treasurer, Interleukin Genetics, Inc., 135 Beaver Street, Waltham, Massachusetts 02452.

GENERAL INFORMATION ABOUT THE ANNUAL MEETING

Why is the Company Soliciting My Proxy?

The Board of Directors of Interleukin is soliciting your proxy to vote at the 2016 annual meeting of stockholders and any adjournments of the meeting, which we refer to as the annual meeting. The proxy statement along with the accompanying Notice of Annual Meeting of Stockholders summarizes the purposes of the meeting and the information you need to know to vote at the Annual Meeting.

We have made available to you on the Internet or have sent you this proxy statement, the Notice of Annual Meeting of Stockholders, the proxy card and a copy of our 2015 annual report because you owned shares of our stock on the record date of August 30, 2016. On or about September 9, 2016, we commenced distribution of the Notice, and, if applicable, the proxy materials to stockholders.

Why Did I Receive a Notice in the Mail Regarding the Internet Availability of Proxy Materials Instead of a Full Set of Proxy Materials?

As permitted by the rules of the U.S. Securities and Exchange Commission, or the SEC, we may furnish our proxy materials to our stockholders by providing access to such documents on the Internet, rather than mailing printed copies of these materials to each stockholder. Most stockholders will not receive printed copies of the proxy materials unless they request them. We believe that this process should expedite stockholders’ receipt of proxy materials, lower the costs of the annual meeting and help to conserve natural resources. If you received a Notice by mail or electronically, you will not receive a printed or email copy of

1

the proxy materials, unless you request one by following the instructions included in the Notice. Instead, the Notice instructs you as to how you may access and review all of the proxy materials and submit your proxy on the Internet. If you requested a paper copy of the proxy materials, you may authorize the voting of your shares by following the instructions on the proxy card, in addition to the other methods of voting described in this proxy statement.

Who Can Vote?

Only stockholders who owned our common stock at the close of business on August 30, 2016 are entitled to vote at the annual meeting. On this record date, there were 229,331,606 shares of our common 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.

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 your name through our stock transfer agent, Computershare Limited, or you have stock certificates, you may vote:

• By Internet or by telephone.  Follow the instructions on the proxy card to vote by Internet or telephone.

• By mail.  Complete and mail the enclosed proxy card in the enclosed postage prepaid envelope. Your proxy will be voted in accordance with your instructions. If you sign the proxy card but do not specify how you want your shares voted, they will be voted as recommended by our Board of Directors.

• In person at the meeting.  If you attend the meeting, you may deliver your completed proxy card in person or you may vote by completing a ballot, which will be available at the meeting.

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:

• By Internet or by telephone.  Follow the instructions you receive from your broker to vote by Internet or telephone.

• By mail.  You will receive instructions from your broker or other nominee explaining how to vote your shares.

• In person at the meeting.  Contact the broker or other nominee who holds your shares to obtain a broker’s proxy card and bring it with you to the meeting. You will not be able to vote at the meeting unless you have a proxy card from your broker.

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

The Board of Directors recommends that you vote as follows:

• “FOR” the election of William C. Mills III and Joseph M. Landstra as Class I directors for a three-year term expiring at our 2019 annual meeting;

• “FOR” the ratification of the appointment of Grant Thornton LLP as our independent public accounting firm for the fiscal year ending December 31, 2016;

• “FOR” the compensation of our named executive officers, as disclosed in this proxy statement;

2

• “FOR” approval of an amendment to our Restated Certificate of Incorporation (the “Charter”), to increase the number of authorized shares of common stock from 450,000,000 to 650,000,000 at any time prior to the earlier of (i) October 1, 2017 and (ii) the 2017 annual meeting of stockholders; and

• “FOR” approval of an amendment to our Charter to effect a reverse stock split by combining outstanding shares of our common stock into a lesser number of outstanding shares by a ratio of not less than 1-for-15 and not more than 1-for-60 at any time prior to the earlier of (i) October 1, 2017 and (ii) the 2017 annual meeting of stockholders, with the exact ratio to be set within this range by our board of directors in its sole discretion (the “reverse stock split”).

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 presented at the annual meeting, other than those discussed in this proxy statement.

May I Change or Revoke My Proxy?

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

• by signing a new proxy card with a later date and submitting it as instructed above;

• by re-voting by Internet or by telephone as instructed above (only your latest Internet or telephone vote will be counted);

• by notifying our Secretary in writing before the annual meeting that you have revoked your proxy; or

• by attending the meeting in person and voting in person.

Attending the meeting in person will not in and of itself revoke a previously submitted proxy unless you specifically request it.

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. 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, 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 holder of record that holds your shares as described above under “How Do I Vote?,” the bank, broker or other holder of record has the authority to vote your unvoted shares only on (1) the ratification of our independent public accounting firm (Proposal 2), (2) the approval of the amendment to our Charter to increase the number of authorized shares of common stock from 450,000,000 to 650,000,000 (Proposal 4), and (3) the approval of the amendment to our Charter to effect the reverse stock split (Proposal 5), even if it does not receive instructions from you, but does not have such discretionary authority on any other proposal. 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 Proposals and How are Votes Counted?

Proposal 1:  Elect William C. Mills III and Joseph M. Landstra as Class I Directors	The two nominees for director who receive the most votes (also known as a “plurality” of the votes) will be elected. You may vote either FOR Mr. Mills and Mr. Landstra or WITHHOLD your vote from both nominees or any one nominee. Votes that are withheld will not be included in the vote tally. Banks and brokerage firms do not have authority to vote customers’ unvoted shares held by the firms in street name for the election of directors. As a result, any shares not voted by a customer will be treated as a broker non-vote. Such broker non-votes will have no effect on the results of this vote.
Proposal 2:  Ratification of Appointment of Our Independent Public Accountant	The affirmative vote of a majority of the votes present in person or represented by proxy and entitled to vote at the annual meeting is required to ratify the appointment of Grant Thornton LLP as our independent public accounting firm. Abstentions will be treated as votes against this proposal. Banks and 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 2016, our Audit Committee of the Board of Directors will reconsider its selection.
Proposal 3:  An Advisory Vote on Compensation of Our Named Executive Officers	The affirmative vote of a majority of the votes present in person or represented by proxy and entitled to vote at the annual meeting is required to approve, on an advisory basis, the compensation of our named executive officers, as described in this proxy statement. Abstentions will be treated as votes against this proposal. Brokerage firms do not have authority to vote customers’ unvoted shares held by the firms in street name on this proposal. As a result, any shares not voted by a customer will be treated as a broker non-vote. Such broker non-votes will have no effect on the results of this vote. Although the advisory vote is non-binding, the Compensation Committee and the Board of Directors will review the voting results and take them into consideration when making future decisions regarding executive compensation.
Proposal 4:  Approval of the Amendment to Our Charter to Increase the Number of Authorized Shares of Our Common Stock	The affirmative vote of a majority of our outstanding common stock is required to approve this amendment to our Charter. Banks and 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 the same effect as a vote against this proposal. Abstentions will have the same effect as a vote against this proposal.
Proposal 5:  Approval of the Amendment to Our Charter to Effect the Reverse Stock Split	The affirmative vote of a majority of our outstanding common stock is required to approve the amendment to our Charter to effect the reverse stock split. Banks and 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 the same effect as a vote against this proposal. Abstentions will have the same effect as a vote against this proposal.

Is Voting Confidential?

We will keep all the proxies, ballots and voting tabulations private. We will only let our Inspector of Elections, Computershare Limited, 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.

4

Where Can I Find the Voting Results of the Annual Meeting?

The preliminary voting results will be announced at the Annual Meeting, and we will publish preliminary, or final results if available, in a Current Report on Form 8-K within four business days of the Annual Meeting. If final results are unavailable at the time we file the Form 8-K, then we will file an amended report on Form 8-K to disclose the final voting results within four business days after the final voting results are known.

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. to assist in the distribution of proxies and accompanying materials to brokerage houses and institutions for an estimated fee of $15,000 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.

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 stock having voting power 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, October 20, 2016 at the offices of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., our legal counsel, located at One Financial Center, Boston, Massachusetts 02111. When you arrive at the meeting, signs will direct you to the appropriate meeting room. 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 1-866-540-7095.

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:

• If your shares of our common stock are registered in your own name, please contact our transfer agent, and inform them of your request by calling them at 1-866-540-7095 or writing them at 250 Royall Street, Canton, MA. 02021.

• If a broker or other nominee holds your shares, please contact the broker or other nominee directly and inform them of your request. Be sure to include your name, the name of your brokerage firm and your account number.

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 August 15, 2016 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 that may be acquired by an individual or group within 60 days following August 15, 2016 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 shown to be beneficially owned by them based on information provided to us by these stockholders. Percentage ownership is based on a total of 229,329,744 shares of our common stock issued and outstanding on August 15, 2016.

Director Independence

Our Board of Directors has determined that the following members qualify as independent directors under the definition promulgated by The NASDAQ Stock Market LLC: Lionel Carnot, Roger C. Colman, Joseph M. Landstra, William C. Mills III, Dayton Misfeldt and James Weaver.

Committees of the Board of Directors and Meetings

Committees.  Our Board of Directors has established three standing committees, Audit, Compensation and Nominating, each as described below.

Meeting Attendance.  During the fiscal year ended December 31, 2015, the Board of Directors met six times and acted by unanimous written consent on one occasion. Each of our incumbent 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. All eight of our directors attended our 2015 annual meeting of stockholders.

Audit Committee and Financial Experts

Our Audit Committee currently consists of William C. Mills III (Chair), Lionel Carnot and Joseph Landstra. Our Audit Committee met four times during the fiscal year ended December 31, 2015. 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. Messrs. Mills and Landstra satisfy the current independence standards promulgated by NASDAQ, as such standards apply specifically to members of audit committees. The Board of Directors has determined that Mr. Mills is an “audit committee financial expert” as the Securities and Exchange Commission has defined that term in Item 407 of Regulation S-K. A copy of the Audit Committee’s written charter is publicly available on our website at www.ilgenetics.com.

11

Compensation Committee

Our Compensation Committee currently consists of Dayton Misfeldt (Chair), Roger C. Colman and William C. Mills III. Our Compensation Committee met six times and acted by unanimous written consent on two occasions during the fiscal year ended December 31, 2015. 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 and stock awards under our stock plans. 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 NASDAQ. A copy of the Compensation Committee’s written charter is publicly available on our website at www.ilgenetics.com.

Nominating Committee

Our Nominating Committee currently consists of Roger C. Colman (Chair) and Lionel Carnot. Our Nominating Committee met one time and acted by unanimous written consent on one occasion during the fiscal year ended December 31, 2015. All members of the Nominating Committee qualify as independent under the definition promulgated by the NASDAQ. 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 the particular nominees. The Nominating Committee may consider candidates recommended by stockholders, as well as from other sources, such as other directors, 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, 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. The Nominating Committee also considers issues of diversity among its members in identifying and considering nominees and strives, if appropriate, to achieve a diverse balance of backgrounds, perspectives and experience. 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 an 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.

Board Leadership Structure and Role in Risk Oversight

Our Board of Directors currently consists of eight directors, each of whom, other than Dr. Kornman and Mr. Carbeau, is independent under NASDAQ’s independence standards. Mr. Carbeau has served as our CEO and a member of our Board since April 2015. Prior to that, Dr. Kornman served as our CEO from August 2012 to April 2015. The Chairman of our Board of Directors is currently Mr. Weaver. The Board has determined that separating the positions of Chief Executive Officer and Chairman of the Board, and having an independent director serve as Chairman of the Board, is in the best interest of shareholders at this time in recognition of the differences between the two roles. Under this structure, the Chief Executive Officer is responsible for setting the strategic direction for the company and for providing the day-to-day leadership over our operations, while the Chairman of the Board provides guidance to the Chief Executive Officer, sets the agenda for Board meetings and presides over meetings of the full Board. In addition, the Chairman approves Board meeting agendas and schedules and generally approves information sent to the Board. This structure ensures a greater role for the independent directors in the oversight of the company and active participation of the independent directors in setting agendas and establishing priorities and procedures for the work of the Board. In addition, our independent directors meet in executive sessions after every scheduled Board meeting.

12

Generally, management is responsible for managing the risks that we face. The Board of Directors is responsible for overseeing management’s approach to risk management that is designed to support the achievement of organizational objectives, including strategic objectives, to improve long-term organizational performance and enhance stockholder value. The involvement of the full Board of Directors in reviewing our strategic objectives and plans is a key part of the Board’s assessment of management’s approach and tolerance to risk. A fundamental part of risk management is not only understanding the risks a company faces and what steps management is taking to manage those risks, but also understanding what level of risk is appropriate for us. In setting our business strategy, our Board of Directors assesses the various risks being mitigated by management and determines what constitutes an appropriate level of risk for us. While the Board of Directors has ultimate oversight responsibility for overseeing management’s risk management process, various committees of the Board of Directors assist it in fulfilling that responsibility. The Audit Committee assists the Board in its oversight of risk management in the areas of financial reporting, internal controls and compliance with certain legal and regulatory requirements and the Compensation Committee assists the board in its oversight of the evaluation and management of risks related to our compensation policies and practices.

Shareholder Communications to the Board

Generally, shareholders who have questions or concerns regarding Interleukin should contact Investor Relations 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:

• junk mail and mass mailings;

• resumes and other forms of job inquiries;

• surveys; and

• solicitations or advertisements.

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.

Kenneth S. Kornman, DDS, Ph.D.

On November 12, 2008, we entered into an employment agreement with Dr. Kornman, our President and Chief Scientific Officer, for a three-year term, commencing on March 31, 2009, the date his previous employment agreement expired. Effective March 31, 2012, this agreement was extended through November 30, 2012. Under this agreement, Dr. Kornman received an initial annual salary of $360,000 and is eligible to receive annual bonuses solely at the discretion of the Board of Directors. Dr. Kornman’s annual salary may be increased in the sole discretion of the Board of Directors. Under the agreement, on November 12, 2008 Dr. Kornman received a stock option to purchase 75,000 shares of common stock, at an exercise price of $0.48 per share, which was the closing price as reported on the NYSE Amex on the grant date. The option was immediately exercisable with respect to 30,000 shares and vests with respect to an additional 15,000 shares on each of March 31, 2010, 2011, and 2012. Under the agreement, Dr. Kornman is entitled to participate in employee benefit plans that we provide or may establish for the benefit of our executive management generally. In addition, while Dr. Kornman remains employed by us, we will reimburse him $3,296 annually for payment of life insurance premiums.

The agreement is terminable immediately by us with cause or upon thirty days prior written notice without cause. The agreement is terminable by Dr. Kornman upon thirty days prior written notice. If we terminate Dr. Kornman without cause or Dr. Kornman terminates his employment with good reason, then, in addition to payment of any accrued, but unpaid compensation prior to the termination, we must continue to pay his base salary and to provide health insurance benefits until the earlier of (1) expiration of the agreement or (2) twelve months. If we terminate Dr. Kornman in connection with a Cessation of our Business (as defined in the agreement), then, in addition to payment of any accrued, but unpaid compensation prior to the termination, we must continue to pay his base salary and to provide health insurance benefits until the earlier of (1) expiration of the agreement or (2) three months. The agreement also includes non-compete and non-solicitation provisions for a period of twelve months following the termination of Dr. Kornman’s employment.

On March 31, 2010, Dr. Kornman was issued 12,500 shares of restricted stock under a restricted stock agreement dated April 30, 2008. In April 2010, as part of the year-end compensation process, the Compensation Committee granted Dr. Kornman an option to purchase 30,000 shares of our common stock. This option is exercisable at $0.745 per share and vests as to 20% of the shares on each of the first five anniversaries of the date of grant.

In May 2011, the Compensation Committee granted Dr. Kornman an option to purchase 100,000 shares of our common stock. This option is exercisable at $0.46 per share and vests as to 25% of the shares on each of the first four anniversaries of the date of grant.

On April 25, 2012, we executed an amendment, effective as of March 31, 2012, to Dr. Kornman’s employment agreement to extend the term through November 30, 2012. In connection with the resignation of our former Chief Executive Officer on August 23, 2012, the Board of Directors appointed Dr. Kornman as Chief Executive Officer in addition to his role as President and Chief Scientific Officer. The Board of Directors also appointed Dr. Kornman as a director to fill the vacancy created by the CEO’s resignation. On November 29, 2012, we entered into a second amendment to Dr. Kornman’s employment agreement to extend the term through November 30, 2015. Effective upon Mr. Carbeau’s appointment as Chief Executive Officer on April 6, 2015, Dr. Kornman resigned as Chief Executive Officer and continues to serve as Interleukin’s President and Chief Scientific Officer and as a member of the Board of Directors.

In December 2012, the Compensation Committee granted Dr. Kornman an option to purchase 300,000 shares of our common stock. This option is exercisable at $0.34 per share and vests as to 25%, 33% and 42% of the shares on each of the first three anniversaries of the date of grant.

In October 2013, Dr. Kornman was granted an option to purchase 2,250,000 shares of our common stock. This option has an exercise price of $0.3799, the fair value of our common stock on the grant date of the option, and will vest as to ¼ of the shares on the first anniversary of the grant date, and as to  1/36 of the remaining shares at the end of each month thereafter beginning on October 31, 2014. In January 2015, Dr. Kornman was granted an option to purchase 2,030,000 shares of our common stock. This option has an exercise price of $0.26, the fair value of our common stock on the grant date of the option, and will vest as to  1/48 of the shares at the beginning of each month beginning on February 1, 2015.

On December 14, 2015, we entered into a new Employment Agreement with Dr. Kornman to continue to serve as our President and Chief Scientific Officer. The new agreement was effective as of December 1, 2015 and replaced the employment agreement, dated November 12, 2008, as amended on March 31, 2012 and November 29, 2012, which terminated by its terms on November 30, 2015. Pursuant to the new agreement, Dr. Kornman will receive an annual base salary of $360,000 per year and is eligible to receive an annual bonus at a target amount of up to 35% of his base salary. Under the terms of the Agreement, Dr. Kornman was granted options to purchase up to 400,000 shares of our common stock at an exercise price of $0.07 per share (the closing price of the common stock on December 14, 2015). The options will vest over 4 years with  1/48^th of the shares to vest on the first day of each successive month beginning January 1, 2016, provided that he remains employed by us on the vesting date. In addition, if at any time within 90 days prior to or 12 months following a Change in Control (as defined in the new agreement), Dr. Kornman is terminated without Cause (as defined in the new agreement), the options will vest in full as of the date of such termination. The new agreement also provides that if Dr. Kornman’s employment with Interleukin is terminated by us without Cause, subject to his execution of a release of claims agreement acceptable to us, he will be entitled to severance payments equal to six months of base salary.

In January 2016, Dr. Kornman was granted an option to purchase 400,000 shares of our common stock. This option has an exercise price of $0.05, the fair value of our common stock on the grant date of the option, and will vest as to ¼ of the shares on the first anniversary of the grant date, and as to  1/36 of the remaining shares at the end of each month thereafter beginning on February 1, 2017.

Scott Snyder

On December 26, 2012, we entered into an employment agreement with Scott Snyder for the position of Chief Marketing Officer beginning on January 2, 2013. The agreement provided for a minimum annual base salary of $265,000, and he was eligible for a bonus under Interleukin’s bonus plan. Mr. Snyder’s employment with Interleukin terminated effective November 13, 2015.

We will pay Mr. Snyder any compensation that is earned but unpaid prior to termination, and an amount equal to six months of his base salary in effect at the time of the termination with such payment made in equal installments on our regularly-scheduled payroll dates.

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 with related persons since January 1, 2014. 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.

On October 26, 2009, we entered into a Merchant Network and Channel Partner Agreement with Amway Corp. d/b/a Amway Global, a subsidiary of Alticor, Inc., which is the parent company of Pyxis Innovations Inc., a stockholder of Interleukin. Pursuant to this Agreement, Amway Global sells our Inherent Health brand of genetic tests through its e-commerce Web site via a hyperlink to our e-commerce site. Amway Global receives a commission equal to a percentage of net sales received by us from Amway Global customers. The agreement has an initial term of 12 months and is automatically renewable for successive 12-month terms. The agreement may be terminated by either party upon 120 days written notice. As of the date of this prospectus, we have paid Amway Global approximately $3.1 million in commissions under this agreement, including $218,000 in 2014, $302,000 in 2015 and $152,000 in the six months ended June 30, 2016.

Beginning in September 2012 and again in 2013, Access Business Group LLC (“ABG”), an affiliate of Alticor, placed purchase orders totaling approximately $3.3 million consisting of weight management kits. The kits are included as part of a promotional bundle of products that Amway is now selling to their Individual Business Owners (IBOs). Of the $3.3 million in orders $1.8 million was received in 2013 for the 2014 program and $1.5 million for the 2013 program. Cash for the kits purchased for the 2013 program was received in the first quarter of 2013 and cash for the kits purchased for the 2014 program was received by December 31, 2013. As a component of the promotional program, and not reflective of actual product expiry, the kits were required to be redeemed by a certain date. The initial program required redemption by December 31, 2013, but the date of required redemption was extended such that the revenues will remain deferred until those kits are redeemed or the breakage analysis determines the probability of eventual redemption is remote. In February 2014, we removed the redemption date requirement, for which ABG paid

20

us $519,000 as a retrospective increase in the product purchase price. In October 2014, we received $250,000 as a retrospective increase in the product purchase price for unsold kits as consideration for extending the required redemption date of the 2014 promotional program to December 31, 2017. Cash received for these kits will be treated as deferred revenues until specific kits are returned for processing or on the final allowed redemption date of December 31, 2017.

On September 21, 2012, we entered into a License Agreement with Access Business Group International LLC (“ABGI”), an affiliate of Alticor. Pursuant to the License Agreement, we have granted ABGI and its affiliates a non-exclusive license to use the technology related to our Weight Management genetic test and to sell the Weight Management test in Europe, Russia and South Africa (the “Territories”). ABGI, or a laboratory designated by ABGI or an affiliate of ABGI, will be responsible for processing the tests, and we will receive a royalty for each test sold, which royalty will increase if certain pending patent applications are issued. The License Agreement has an initial term of five years from the date of first commercial sale of the Weight Management test under the agreement. Thereafter, the term will automatically renew for additional one-year periods unless at least 60 days prior notice is delivered by either party. To date, we have been paid approximately $658,170 under this agreement, including $128,790 in 2014, $173,880 in 2015. For the six months ended June 30, 2016, $105,998 was earned.

In connection with the execution of the License Agreement, we and ABGI also entered into a Professional Services Agreement (the “PSA”) pursuant to which we have agreed to provide services to ABGI in connection with its sale and processing of the tests within the Territories. Services will be provided pursuant to a statement of work to be entered into from time to time between the parties. Such statements of work will also specify the fees to be paid by ABGI to us for such services. The PSA has no set term and may be terminated by either party, subject to certain conditions. As of the date of this prospectus, we have been paid $5,250 under this agreement, all being received in 2013.

We have also entered into an agreement with Pyxis containing certain terms for allocating opportunities as permitted under Section 122(17) of the Delaware General Corporation Law. This agreement regulates and defines the conduct of certain of our affairs as they may involve this stockholder and its affiliates, and the powers, rights, duties and liabilities of us and our officers and directors in connection with corporate opportunities. Except under certain circumstances, this stockholder 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, its affiliates, or one of our directors appointed by Pyxis acquire knowledge of a potential transaction or matter that may be a corporate opportunity for both such stockholder and its affiliates and us, to the fullest extent permitted by law, such stockholder and its affiliates will not have a duty to inform us about the corporate opportunity or be liable to us or to our stockholders 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 these agreements 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.

21

On December 23, 2014, we entered into a Securities Purchase Agreement (the “2014 Purchase Agreement”) with various accredited investors (the “2014 Investors”), pursuant to which we sold to the 2014 Investors in a private placement transaction (the “2014 Private Placement”) an aggregate of 50,099,700 shares of our common stock at a price of $0.1003 per share for gross proceeds of approximately $5.025 million. The 2014 Investors also received 2014 Warrants to purchase up to an aggregate of 50,099,700 shares of common stock at an exercise price of $0.1003 per share. The following beneficial owners of more than 5% of our securities participated in the 2014 Private Placement:

2014 Investor	Shares		Warrant Shares		Purchase Price

Growth Equity Opportunities Fund III, LLC		19,868,965		19,868,965	$	1,992,857.17

In addition, Stephen DiPalma, our Interim Chief Financial Officer, purchased 249,252 shares of our common stock and received a 2014 Warrant to purchase 249,252 shares of common stock in the 2014 Private Placement for a purchase price of $25,000.

On December 23, 2014, we also entered into a Registration Rights Agreement with the investors in the 2014 Private Placement and BTIG LLC (the placement agent in the 2014 Private Placement), pursuant to which we are required to file a registration statement on Form S-1 within 45 days of December 23, 2014 to cover the resale of (i) the shares sold in the 2014 Private Placement and the shares of common stock underlying the 2014 Warrants issued in the 2014 Private Placement and (ii) the shares of Common Stock underlying the 2014 BTIG Warrants issued to BTIG LLC and affiliates as placement agent compensation. The failure on the part of Interleukin to satisfy certain deadlines described in the Registration Rights Agreement may subject us to payment of certain monetary penalties.

Effective as of February 1, 2016, we entered into a Services Agreement with Metagenics, Inc. to provide our PerioPredict test to Metagenics’ employees as part of an enhanced employee benefits program. Metagenics is an affiliate of Alticor and Pyxis. Pursuant to this agreement, we will provide genetic testing and patient education to Metagenics employees, as well as dental professional support to their dental providers, and Metagenics will pay a fixed fee for each test processed by us. Through April 30, 2016, we have received no revenue under this agreement.

On July 1, 2016 we entered into an agreement with Amway to provide Interleukin’s PerioPredict Genetic Risk Test and Patient Engagement Platform to Amway’s employees as part of an enhanced employee benefits plan. Under terms of the agreement, we will make PerioPredict available to Amway’s approximately 5,000 employees in the U.S. The program is expected to begin in September 2016.

On July 29, 2016, we entered into the 2016 Purchase Agreement with the 2016 Investors, pursuant to which we sold to the 2016 Investors in the 2016 Private Placement an aggregate of 56,262,571 shares of our common stock at a price of $0.0994 per share for gross proceeds of approximately $5.6 million. The 2016 Investors also received 2016 Warrants to purchase up to an aggregate of 56,262,571 shares of common stock at an exercise price of $0.0994 per share. The following affiliates and beneficial owners of more than 5% of our securities participated in the 2016 Private Placement:

On August 18, 2016, the Board of Directors voted to nominate William C. Mills III and Joseph M. Landstra for election at the annual meeting for a term of three years to serve until the 2019 annual meeting of stockholders, and until their successors have been elected and qualified, or until their earlier death, resignation, retirement or removal. Unless authority to vote for any of these nominees is withheld, the shares represented by a validly executed proxy will be voted FOR the election as directors of Mr. Mills and Mr. Landstra. In the event that either nominee should become unable or unwilling to serve, the shares represented by a validly executed proxy will be voted for the election of such other person as the Board of Directors may recommend in his place, unless the Board chooses to reduce the number of directors serving on the Board. We have no reason to believe that either nominee will be unable or unwilling to serve as a director.

Required Vote for Approval

A plurality of the shares voted at the annual meeting is required to elect each nominee as a director.

The Board of Directors recommends a vote “FOR” the election of William C. Mills III and Joseph M. Landstra as Class I directors, and proxies solicited by the Board will be voted in favor, unless a stockholder indicates otherwise on the proxy.

PROPOSAL 2
 
RATIFICATION OF APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANT

The Audit Committee of the Board has appointed Grant Thornton LLP as our independent public accountant for the fiscal year ending December 31, 2016. The Board proposes that the stockholders ratify this appointment. Grant Thornton LLP has audited our financial statements since 2002. 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.

Principal Accountant Fees and Services

The following table presents fees for professional audit services rendered by Grant Thornton, LLP, our independent public accountant, for the audit of our annual financial statements for the years ended December 31, 2014 and December 31, 2015 and fees billed for other services rendered by Grant Thornton LLP during those periods.

	2014		2015
Audit fees(1)	$	216,786	$	210,345
Audit related fees		—		—
Tax fees		—		—
All other fees		—		—
Total	$	216,786	$	210,345

(1) Audit fees consist of fees for professional services rendered for the audit of our annual financial statements and review of the interim financial statements included in the quarterly reports and fees for services related to the Company’s registration statements, consents and assistance with and review of documents filed with the SEC.

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.

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.

25

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.

Neither our Bylaws nor other governing documents or law require stockholder ratification of the appointment of Grant Thornton LLP as our independent public accountant. However, the Board is submitting the appointment of Grant Thornton LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the appointment, the Audit Committee of the Board will reconsider whether to retain Grant Thornton LLP as the Company’s independent public accountant. Even if the selection is ratified, the Audit Committee of the Board in its discretion may direct the appointment of a different independent public accountant at any time during the year if the Audit Committee determines that such a change would be in the best interests of the company and its stockholders.

Required Vote for Approval

The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the annual meeting will be required to ratify the appointment of Grant Thornton LLP as our independent public accountant.

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

PROPOSAL 3
 
CONSIDER AN ADVISORY VOTE ON COMPENSATION
FOR OUR NAMED EXECUTIVE OFFICERS

We are seeking your advisory vote as required by Section 14A of the Securities Exchange Act of 1934, as amended, on the approval of the compensation of our named executive officers as described in this proxy statement. Because your vote is advisory, it will not be binding on our Compensation Committee or our Board of Directors. However, the Compensation Committee and the Board will review the voting results and take them into consideration when making future decisions regarding executive compensation.

Our compensation philosophy is designed to align each executive’s compensation with our short-term and long-term performance and to provide the compensation and incentives needed to attract, motivate and retain key executives who are crucial to our long-term success. Before voting on this Proposal 3, you are urged to read the section of this proxy statement entitled “Executive Compensation.”

In accordance with the rules adopted by the SEC, the following resolution, commonly known as a “say-on-pay” vote, is being submitted for a stockholder vote at the Annual Meeting:

“RESOLVED, that the compensation paid to the named executive officers of Interleukin Genetics, Inc., as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the compensation tables and the related material disclosed in this proxy statement, is hereby APPROVED.”

Required Vote for Approval

The affirmative vote of a majority of the votes present in person or represented by proxy and entitled to vote at the annual meeting is required to approve, on an advisory basis, the compensation of our named executive officers, as described in this proxy statement.

The Board of Directors recommends a vote “FOR” an advisory vote on compensation for our named executive officers, and proxies solicited by the Board will be voted in favor of such approval unless a stockholder indicates otherwise on the proxy.

PROPOSAL 4
 
APPROVAL OF AN AMENDMENT TO OUR CHARTER TO INCREASE
THE NUMBER OF AUTHORIZED SHARES OF COMMON STOCK

At the annual meeting, our stockholders will be asked to approve an amendment to our Charter to increase our authorized shares of common stock from 450,000,000 shares to 650,000,000 shares.

If this Proposal 4 is approved by the stockholders as proposed, the Board would have the sole discretion to effect the amendment and increase the authorized shares of common stock at any time prior to the earlier of (i) October 1, 2017 and (ii) the 2017 annual meeting of stockholders. The Board would also have the discretion to abandon the amendment entirely prior to its effectiveness. The Board’s determination to effect or abandon the amendment will be based on a number of factors, including whether or not the Board decides to effect a reverse stock split if Proposal 5 is approved. The Board reserves the right, notwithstanding stockholder approval and without further action by the stockholders, to abandon the amendment if, at any time prior to the effectiveness of the filing of the amendment with the Secretary of State, the Board, in its sole discretion, determines that it is no longer in our best interest and the best interests of our stockholders to proceed.

As of August 15, 2016, we had 450,000,000 authorized shares of common stock, par value $0.001 per share, of which 426,120,794 shares were outstanding or reserved for issuance. Of those, 229,329,744 shares were outstanding; 22,052,657 shares were reserved for issuance upon exercise of outstanding stock options; 30,174,743 shares were reserved for issuance under our stock plans and employee stock purchase plan; and 144,563,650 shares were reserved for the exercise of outstanding warrants to purchase common stock. We currently have no plans arrangements or understandings to issue any of the shares that would be newly available for issuance following approval of this proposal.

The Board of Directors believes that the currently available unissued shares do not provide sufficient flexibility for corporate action in the future. The Board of Directors believes it is in our best interest to have sufficient additional authorized but unissued shares of common stock available in order to provide flexibility for corporate action in the future. Management believes that the availability of additional authorized shares for issuance from time to time in the Board of Directors’ discretion in connection with future financings, investment opportunities, stock splits or dividends, possible acquisitions or for other corporate purposes is desirable in order to avoid repeated separate amendments to our Charter and the delay and expense incurred in holding special meetings of the stockholders to approve such amendments. The Board of Directors believes that the currently available unissued shares do not provide sufficient flexibility for corporate action in the future.

We will not solicit further authorization by vote of the stockholders for the issuance of the additional shares of common stock proposed to be authorized, except as required by law, regulatory authorities or rules of any stock exchange on which our shares may then be listed. The issuance of additional shares of common stock could have the effect of diluting existing stockholder earnings per share, book value per share and voting power. Our common stockholders do not have any preemptive right to purchase or subscribe for any part of any new or additional issuance of our securities.

The form of the proposed amendment to our Charter to increase the number of authorized shares of common stock is attached as Annex A to this proxy statement.

Required Vote for Approval

The affirmative vote of a majority of our outstanding common stock is required to approve this amendment to our Charter.

The Board of Directors recommends a vote “FOR” approval of the amendment to our charter to increase the number of authorized shares of common stock, and proxies solicited by the Board will be voted in favor of such approval unless a stockholder indicates otherwise on the proxy.

28

PROPOSAL 5
 
APPROVAL OF AN AMENDMENT TO OUR CHARTER TO EFFECT A REVERSE STOCK
SPLIT OF OUR COMMON STOCK AT A RATIO IN THE RANGE OF 1-FOR-15 TO 1-FOR-60

General

At the annual meeting, our stockholders will be asked to approve an amendment to our Charter to effect a reverse stock split of the issued and outstanding shares of our common stock (such split to combine any whole number of shares of outstanding common stock between and including fifteen (15) and sixty (60) into one (1) share of common stock). Upon the effectiveness of the amendment to our Charter effecting the reverse stock split, the outstanding shares of our common stock will be reclassified and combined into a lesser number of shares such that one share of our common stock will be issued for a specified number of shares.

If this Proposal 5 is approved by the stockholders as proposed, the Board would have the sole discretion to effect the amendment and reverse stock split at any time prior to the earlier of (i) October 1, 2017 and (ii) the 2017 annual meeting of stockholders, and to fix the specific ratio for the reverse stock split, provided that the ratio would be not less than 1-for-15 and not more than 1-for-60. By approving the reverse stock split, our stockholders are approving individual amendments to our Charter for each whole number in such range. After the Board has selected the whole number in such range to effect the reverse stock split, we will abandon all amendments to the Charter except the amendment with respect to the number selected by the Board. The Board would also have the discretion to abandon the amendment entirely prior to its effectiveness. We believe that enabling the board to fix the specific ratio of the reverse stock split within the stated range will provide us with the flexibility to implement the split in a manner designed to maximize the anticipated benefits for our stockholders. The Board’s determination of the ratio of the reverse stock split will be based on a number of factors, including market conditions, existing and expected trading prices for our common stock and The NASDAQ Capital Market or NYSE MKT initial listing requirements. Even if the stockholders approve the reverse stock split, we reserve the right not to effect the reverse stock split if the Board does not deem the reverse stock split to be in the best interests of Interleukin and its stockholders.

The reverse stock split, if approved by our stockholders, would become effective upon the filing of an amendment to our Charter with the Secretary of State of the State of Delaware, or at the later time set forth in the amendment. The exact timing of the amendment will be determined by the Board based on its evaluation as to when such action will be the most advantageous to Interleukin and its stockholders. In addition, the Board reserves the right, notwithstanding stockholder approval and without further action by the stockholders, to abandon the amendment and the reverse stock split if, at any time prior to the effectiveness of the filing of the amendment with the Secretary of State, the Board, in its sole discretion, determines that it is no longer in our best interest and the best interests of our stockholders to proceed.

The form of the proposed amendment to our Charter to effect the reverse stock split is attached as Annex B to this proxy statement. Any amendment to our Charter to effect the reverse stock split will include the reverse stock split ratio fixed by the board, within the range approved by our stockholders. The amendment to our Charter will not change the number of authorized shares, or the par value, of our common stock. We currently have no plans arrangements or understandings to issue any of the shares that would be newly available for issuance following approval of this proposal.

Reasons for the Proposed Amendment

The Board’s primary reasons for approving and recommending the reverse stock split are that the Board believes that:

• the reverse stock split is the most effective means of increasing the per-share market price of our common stock in order to become eligible for listing on The NASDAQ Capital Market or the NYSE MKT; and

• a higher per-share market price of our common stock could encourage investor interest in Interleukin and promote greater liquidity for our stockholders.

Our common stock is currently listed on the OTCQB^TM under the symbol “ILIU.” We believe that becoming listed on The NASDAQ Capital Market or the NYSE MKT will support and maintain the liquidity

29

of our common stock for our stockholders. In order for our common stock to be eligible for listing on The NASDAQ Capital Market, we must satisfy the initial listing requirements established by NASDAQ, including, among other requirements, a minimum bid price of at least $4.00 per share ($3.00 under certain circumstances) for our common stock. In order for our common stock to be eligible for listing on the NYSE MKT, we must satisfy the initial listing requirements established by NYSE, including, among other requirements, a minimum price of $4.00 per share for our common stock.

An objective of the Board in proposing the reverse stock split is to increase the per-share market price of our common stock in order to become eligible for listing on The NASDAQ Capital Market or the NYSE MKT. Effecting the reverse stock split would reduce our total shares of common stock outstanding, which the Board believes will increase the price per share of our common stock and therefore, better enable us to list our common stock on The NASDAQ Capital Market or the NYSE MKT. However, the effect of the reverse stock split on the market value of our common stock cannot be predicted with any certainty, and there can be no assurance that the market price per post-split share will either exceed or remain in excess of the minimum closing price for a sustained period of time. The reverse stock split itself does not affect our market value, and the market price of our common stock may also be based on other factors that are unrelated to the number of shares outstanding, including our future performance.

Effects of the Reverse Stock Split

The reverse stock split will be effected simultaneously for all outstanding shares of our common stock. The reverse stock split will affect all of our stockholders uniformly and will not affect any stockholder’s percentage ownership interests in the company, except to the extent that the reverse stock split results in any of our stockholders owning a fractional share. Common stock issued pursuant to the reverse stock split will remain fully paid and nonassessable. The reverse stock split will not affect our continuing to be subject to the periodic reporting requirements of the SEC.

As of the effective time of the reverse stock split, we will adjust and proportionately decrease the number of shares of our common stock reserved for issuance upon exercise of, and adjust and proportionately increase the exercise price of, all options and warrants and other rights to acquire our common stock. In addition, as of the effective time of the reverse stock split, we will adjust and proportionately decrease the total number of shares of our common stock that may be the subject of the future grants under our stock plans.

Assuming reverse stock split ratios of 1-for-15 and 1-for-60, which are ratios based on whole numbers of shares at the high end and low end of the range that our stockholders are being asked to approve, the following table sets forth the number of shares of our common stock that would be (i) issued and outstanding and (ii) reserved for issuance pursuant to outstanding options or warrants and under our stock plans, after the reverse stock split, based on information as of August 15, 2016:

	Reverse Stock Split Ratio of 1-for-15		Reverse Stock Split Ratio of 1-for-60
Number of Shares of Common Stock Issued and Outstanding		28,408,052		7,102,013
Number of Shares of Common Stock Reserved for Issuance		2,003,641		500,910

After the effective time of the reverse stock split, the post-split market price of our common stock may be less than the pre-split price multiplied by the reverse stock split ratio. In addition, a reduction in number of shares outstanding may impair the liquidity for our common stock, which may reduce the value of our common stock.

Procedure for Effecting the Reverse Stock Split and Exchange of Stock Certificates

If our stockholders approve the proposal to effect the reverse stock split, and if the Board still believes that a reverse stock split is in the best interests of Interleukin and its stockholders, the Board will determine the ratio of the reverse stock split to be implemented. We will file the certificate of amendment with the Secretary of State of the State of Delaware. The Board may delay effecting the reverse stock split without resoliciting stockholder approval. Beginning on the effective date of the reverse stock split, each certificate representing pre-split shares will be deemed for all corporate purposes to evidence ownership of post-split shares.

30

As soon as practicable after the effective date of the reverse stock split, stockholders will be notified that the reverse stock split has been effected. We expect that our transfer agent will act as exchange agent for purposes of implementing the exchange of stock certificates. Holders of pre-split shares will be asked to surrender to the exchange agent certificates representing pre-split shares in exchange for certificates representing post-split shares in accordance with the procedures to be set forth in a letter of transmittal to be sent by us. No new certificates will be issued to a stockholder until such stockholder has surrendered such stockholder’s outstanding certificate(s) together with the properly completed and executed letter of transmittal to the exchange agent. Any pre-split shares submitted for transfer, whether pursuant to a sale or other disposition, or otherwise, will automatically be exchanged for post-split shares. STOCKHOLDERS SHOULD NOT DESTROY ANY STOCK CERTIFICATE(S) AND SHOULD NOT SUBMIT ANY CERTIFICATE(S) UNLESS AND UNTIL REQUESTED TO DO SO.

Fractional Shares

We will not issue fractional shares in connection with the reverse stock split. Instead, stockholders who otherwise would be entitled to receive fractional shares because they hold a number of shares not evenly divisible by the reverse stock split ratio will be entitled, upon surrender to the exchange agent of certificates representing such shares, to a cash payment in lieu thereof at a price equal to the fraction to which the stockholder would otherwise be entitled multiplied by the closing price of the common stock, as reported in the Wall Street Journal, on the last trading day prior to the effective date of the split (or if such price is not available, the average of the last bid and asked prices of the common stock on such day or other price determined by the Board of Directors). The ownership of a fractional interest will not give the holder thereof any voting, dividend, or other rights except to receive payment therefor as described herein.

Accounting Matters

The reverse stock split will not affect the par value of our common stock. As a result, at the effective time of the reverse stock split, the stated capital on our balance sheet attributable to the common stock will be reduced in the same proportion as the reverse stock split ratio, and the additional paid-in capital account will be credited with the amount by which the stated capital is reduced. The per share net income or loss and net book value of our common stock will be increased because there will be fewer shares of our common stock outstanding. Prior periods’ per share amounts will be restated to reflect the reverse stock split.

Appraisal Rights

Under the Delaware General Corporation Law, our stockholders are not entitled to appraisal rights with respect to the reverse stock split, and we do not intend to independently provide stockholders with any such right.

Certain Material U.S. Federal Income Tax Consequences of the Reverse Stock Split

The following summary describes certain material U.S. federal income tax consequences of the reverse stock split to holders of our common stock. This summary is based upon current provisions of the Internal Revenue Code of 1986, as amended (the “Code”), existing Treasury Regulations and current administrative rulings and court decisions, all of which are subject to change and to differing interpretations, possibly with retroactive effect.

This summary addresses the tax consequences only to a “U.S. person,” which is a beneficial owner of our common stock that is either:

• a citizen or resident of the United States;

• a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) organized under the laws of the United States, any state thereof or the District of Columbia;

• an estate, the income of which is subject to U.S. federal income taxation regardless of its source; and

• a trust if either (i) a court within the United States is able to exercise primary supervision over the administration of such trust and one or more U.S. persons have the authority to control all substantial decisions of such trust or (ii) the trust has a valid election in effect to be treated as a U.S. person for U.S. federal income tax purposes.

31

If a partnership (or other entity classified as a partnership for U.S. federal income tax purposes) is the beneficial owner of our common stock, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. If you are a partner of a partnership holding our common stock, you should consult your tax advisor.

This summary assumes that our stockholders hold their shares of our common stock as capital assets within the meaning of Section 1221 of the Code (generally, property held for investment). No attempt has been made to comment on all U.S. federal income tax consequences of the reverse stock split that may be relevant to particular holders, including holders:

• who are subject to special treatment under U.S. federal income tax rules such as dealers in securities, financial institutions, non-U.S. persons, mutual funds, regulated investment companies, real estate investment trusts, insurance companies, tax-exempt entities, U.S. expatriates, or traders in securities who elect to mark to market;

• who acquired their shares in connection with stock option or stock purchase plans or in other compensatory transactions;

• who hold their shares as qualified small business stock within the meaning of Section 1202 of the Code;

• who hold their shares as part of an integrated investment such as a hedge or as part of a hedging, straddle or other risk reduction strategy; or

• who do not hold their shares as capital assets.

In addition, the following discussion does not address the tax consequences of the reverse stock split under state, local and foreign tax laws or under the alternative minimum tax provisions of the Code. Furthermore, the following discussion does not address any of the tax consequences of transactions effectuated before, after or at the same time as the reverse stock split, whether or not they are in connection with the reverse stock split, including, without limitation, transactions in which shares of our common stock are acquired or disposed of.

Accordingly, holders of our common stock are advised and expected to consult their own tax advisors regarding the U.S. federal income tax consequences of the reverse stock split to them in light of their personal circumstances and the consequences of the reverse stock split under state, local and foreign tax laws.

The reverse stock split is intended to qualify as a “reorganization” under Section 368 of the Code. Assuming the reverse stock split qualifies as a reorganization, and subject to the note below regarding the receipt of an additional fraction of a share, a U.S. holder generally will not recognize gain or loss upon the exchange of pre-split shares for post-split shares. The aggregate tax basis of the post-split shares received by a U.S. holder in the reverse stock split will be the same as the aggregate tax basis in the pre-split shares surrendered by such U.S. holder. The holding period for the post-split shares received by a U.S. holder in the reverse stock split will include the period during which the pre-split shares surrendered by such U.S. holder in the reverse stock split were held.

As noted above, we will not issue fractional shares in connection with the reverse stock split. Instead, stockholders who otherwise would be entitled to receive fractional shares because they hold a number of shares not evenly divisible by the reverse stock split ratio will automatically be entitled to receive an additional fraction of a share of common stock to round up to the next whole post-split share. The U.S. federal income tax consequences of the receipt of such an additional fraction of a share of common stock is not clear. If the receipt of such an additional fraction of a share of common stock is taxed as a dividend, however, any tax liability associated with such receipt is not expected to be material.

32

Required Vote for Approval

The affirmative vote of a majority of our outstanding common stock is required to approve this amendment to our Charter.

The Board of Directors recommends a vote “FOR” approval of the amendment to our charter to effect the reverse stock split, and proxies solicited by the Board will be voted in favor of such approval unless a stockholder indicates otherwise on the proxy.
