Explanatory Note

This Amendment No. 13 is filed for the purpose of providing information regarding the issuance by the Issuer to Pyxis of a promissory note in the principal amount of $2,000,000, as more fully described in Item 4(a) below.

Item 1. Security and Issuer.

Name of Issuer:
	Interleukin Genetics, Inc.
Title of Class of Equity Securities:
	Common Stock $.001 Par Value
Address of Issuer’s Principal Executive Office:
	135 Beaver Street Waltham, MA 02452

Item 2. Identity and Background.

The information set forth in Item 2 of Amendment No. 13 is incorporated herein by reference.

Item 3. Source and Amount of Funds or Other Consideration.

   On November 9, 2011, Pyxis loaned $2,000,000 to the Issuer as part of a credit facility described in more detail in Item 4(a) below.  The source of Pyxis’ funds for this transaction was an intercompany loan from Alticor Inc. to Pyxis.

            In addition, the information set forth in Item 3 of Amendment No. 10 and Amendment No. 8 is incorporated herein by reference.

Item 4. Purpose of Transaction.

The information set forth in Item 4 of Amendment No. 8 is incorporated herein by reference.

    (a)        As previously disclosed in Amendment No. 8, on March 10, 2009, Pyxis and the Issuer entered into an Amended and Restated Note Purchase Agreement, pursuant to which Pyxis extended the term of a credit facility to March 31, 2010 and provided that all borrowings under the credit facility would be due on August 16, 2011.  The notes issued under the credit facility are convertible into shares of the Issuer’s common stock (the “Common Stock”) at a conversion price equal to $5.6783 per share.

            As previously disclosed, Pyxis and the Issuer entered into a number of amendments to the credit facility, including a Third Amendment to Amended and Restated Note Purchase Agreement (the “Third Amendment”), which was previously disclosed in Amendment No. 12 and pursuant to which Pyxis extended the term of the credit facility to June 30, 2012.

            The Issuer has elected to draw down an additional $2,000,000 under the credit facility in exchange for a promissory note issued to Pyxis on October 31, 2011 (the “October 2011 Note” and, together with promissory notes previously issued under the credit facility, the “Notes”), leaving $1,316,255 in total availability under the credit facility.

            The Amended and Restated Note Purchase Agreement, as amended, is referred to herein as the “Note Purchase Agreement.”

Item 5. Interest in Securities of the Issuer.

(a)           Pyxis beneficially owns 37,339,021 shares of the Issuer’s stock, which is approximately 55.6% of the sum of the number of the Issuer’s Common Stock that was

outstanding as of July 31, 2011 (as reported in the Issuer’s most recent Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission) plus the number of shares that would have been outstanding upon conversion of all of the preferred stock and the convertible notes held by Pyxis as of November 9, 2011.

          Alticor Inc., Solstice Holdings Inc., and Alticor Global Holdings Inc. may be deemed to beneficially own the same 37,339,021 shares of the Issuer’s stock.

          The number of shares reported in this Item 5(a) includes 6,884,056 shares of Common Stock owned directly by Pyxis (as of November 9, 2011), 28,160,200 shares of Common Stock issuable to Pyxis upon conversion of its 5,000,000 shares of Series A Preferred Stock (as of November 9, 2011) and 2,294,765 shares of Common Stock issuable to Pyxis upon conversion of the Notes.  In determining Pyxis’ beneficial ownership percentage above, a division calculation is used wherein 37,339,021 is the numerator and the denominator is equal to the sum of: (a) all shares of Common Stock outstanding (as reported by the Issuer), (b) 28,160,200 shares issuable to Pyxis upon the conversion of the Series A Preferred Stock, and (c) 2,294,765 shares issuable to Pyxis upon the conversion of the Notes.

The calculations in this Item 5(a) are based on the Issuer having 36,684,256 shares of Common Stock outstanding as of July 31, 2011, as reported in the Issuer’s most recent Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission.  In addition, these calculations assume no outstanding options or other rights to obtain Common Stock have been exercised by their holders except for the conversion of the Series A Preferred Stock and convertible notes by Pyxis as described herein or as otherwise indicated by the Issuer.

None of the other persons named in Item 2 of Amendment No. 13 is the beneficial owner of the Common Stock except to the extent beneficial ownership of shares owned by Pyxis may be attributed to such person.

(b)           Pyxis holds the sole power to vote and dispose of the securities of the Issuer that it holds.  Alticor Inc., Solstice Holdings Inc., and Alticor Global Holdings Inc. have the power to direct the voting and disposition of the securities of the Issuer held by Pyxis by virtue of their direct or indirect control of Pyxis.

(c)           None

(d)           Not applicable

(e)           Not applicable

The responses to (a) of this Item 5 are “Not Applicable” for the Directors and Officers named in Item 2 of Amendment No. 13.  The responses to paragraph (b) and (c) of this Item 5 are “Not Applicable” and “None”, respectively, for Alticor Inc., Solstice Holdings Inc., Alticor Global Holdings Inc., and the Directors and Officers named in Item 2 of Amendment No. 13.

In addition, the information included in Item 4 above and in Item 4 of Amendment No. 8 is incorporated herein by reference.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

The information set forth in Item 6 of Amendment No. 8 and in Item 4 of this Amendment No. 13, Amendment No. 12, Amendment No. 11, Amendment No. 10 and Amendment No. 9 is incorporated herein by reference.
