COUNTY OF DALLAS

I Robert C. Blattberg, residing at 232 E. Walton Place, Chicago, Illinois 60611, do hereby
appoint the employees of the Mannatech Finance Department of Mannatech, Incorporated, a
Texas corporation, and Stephen D. Fenstermacher, my true and lawful attorneys-in-fact (each an
"Attorney-in-Fact" and, collectively, the "Attorneys-in-Fact"), each, individually or jointly, to
have full power to act in my name, place and stead and on my behalf to do and execute all or any
of the following acts, deeds and things:

1)	To execute and file for and on behalf of me, in my capacity as one or more of an
officer, director, or significant stockholder of Mannatech, Incorporated or any of
its subsidiaries (collectively, the "Company"), reports or other filings under
Section 16 of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), and the rules thereunder, including without limitation, Forms 3, 4 and
5,including any amendments, corrections, supplements or other changes thereto;

2)	To do and perform any and all acts for and on behalf of me which you (in your
sole discretion) determine may be necessary or desirable to complete and execute
any such reports or other filings and timely file same with the United States
Securities and Exchange Commission and any stock exchange or similar
authority; and
3)	To take any other action of any type whatsoever in connection with the foregoing
which, in the sole opinion of such Attorney-in-Fact, may be of benefit to, in the
interest of, or legally required by me, it being understood that the documents
executed by such Attorney-in-Fact on behalf of me pursuant to this Power of
Attorney shall be in such form and shall contain such terms and conditions as
such Attorney-in-Fact may approve in such Attorney-in-Fact's discretion.

      I hereby grant to each Attorney-in-Fact full power and authority to do and perform any
and every act and thing whatsoever requisite, necessary, or proper to be done (in such Attorney-
in-Fact's sole discretion) in the exercise of any of the rights and powers herein granted, as fully
to all intents and purposes as I might or could do if personally present, with full power of
substitution or revocation, hereby ratifying and confirming all that the Attorneys-in-Fact shall
lawfully do or cause to be done by virtue of this Power of Attorney and the rights and powers
herein granted. I acknowledge that the Attorneys-in-Fact, in serving in such capacity at my
request, are not assuming, nor is the Company assuming, any of my responsibilities to comply
with Section 16 of the Exchange Act.
      This Power of Attorney shall remain in full force and effect until I am no longer subject
to Section 16 of the Exchange Act with respect to my holdings of and transactions in securities
issued by the Company, unless earlier revoked by me in a signed writing delivered to the
Attorneys-in-Fact.

the invalidity or unenforceability of any provision hereof shall not affect the validity or
enforceability of any other provision hereof; provided that if any provision of this Power of
Attorney, as applied to me or to any Attorney-in-Fact or any circumstance, is adjudged by any
governmental body, arbitrator or mediator not to be enforceable in accordance with its terms,
then such governmental body, arbitrator or mediator shall have the power to modify the
provision in a manner consistent with the objectives of this Power of Attorney such that it is
enforceable, and/or to delete specific words or phrases, and in its reduced form, such provision
shall be enforceable and shall be enforced, but in any case, only to the extent- required to make
such provision enforceable.
      Governing Law. This agreement shall be deemed to be a contract under, and shall be
construed, interpreted and governed by and according to, the laws of the State of Texas,
excluding any conflict of laws principle which, if applied, might permit or require the application
