Dear Sirs:

              We are acting as counsel to Integrated BioPharma, Inc., a Delaware
corporation (the "Company"), in connection with the Registration Statement on
Form S-3 filed on June 27, 2007 (as it may be amended, the "Registration
Statement"), under the Securities Act of 1933, as amended (the "Act"), covering
2,300,000 shares of the Company's common stock, par value $.002 per share (the
"Common Stock"), which are being registered in connection with the proposed sale
of the shares of Common Stock by the selling stockholders listed therein.

              We have examined the originals, or certified, conformed or
reproduction copies, of all such records, agreements, instruments and documents
as we have deemed relevant or necessary as the basis for the opinion hereinafter
expressed. In all such examinations, we have assumed the genuineness of all
signatures on originals or certified copies and the conformity to original or
certified copies of all copies submitted to us as conformed or reproduction
copies. As to various questions of fact relevant to such opinion, we have relied
upon, and assumed the accuracy of, certificates and oral or written statements
and other information of or from public officials, officers or representatives
of the Company, and others.

              Based upon the foregoing, and the laws of the State of Delaware,
we are of the opinion that the 2,300,000 shares of Common Stock included in the
Registration Statement have been duly authorized, and, when issued, delivered
and paid for in accordance with the terms and conditions of the instruments
governing their issuance, will be legally issued, fully paid, non-assessable and
binding obligations of the Company under the laws of the State of Delaware.

              We hereby consent to the filing of this opinion as an exhibit to
the Registration Statement and to the reference to this firm under the caption
"Legal Matters" in the prospectus forming a part of the Registration Statement.


                                                Very truly yours,

                                                /s/ Greenberg Traurig, LLP
