NEWS RELEASE

COPPELL, Texas, Feb 01, 2012 (BUSINESS WIRE) --It's official. Mannatech, Incorporated (NASDAQ: MTEX), the provider of nutritional supplements and skin care products based on Real Food Technology^(R) solutions, and the Texas Woman's University (TWU) announced that the very first online classes for "Nutrition and Personal Health Coaching" will start today.

Taught by highly qualified TWU faculty, including Dr. Chandan Prasad, Professor and Chairman of the Department of Nutrition and Food Sciences at TWU, this 45-hour self-paced course will be available to both health professionals and members of the general public who want to know more about health and nutrition. There are three classes beginning today--made up of 77 students, representing eight different countries that include USA, Canada, Australia, Mexico, South Africa, Japan, Singapore and the Netherlands.

As part of TWU's curriculum, Dr. Rob Sinnott, CEO and Chief Science Officer at Mannatech, will be guest lecturing on the Dietary Supplement Health and Education Act (DSHEA) of 1994. Check out the TWU video on Mannatech's YouTube page to hear a little bit about the course directly from Dr. Prasad and Dr. Sinnott.

Dr. Rolando L. Maddela, Mannatech Manager of Clinical Research Administration, who has been working with Dr. Prasad on the startup of the program says, "As a consequence of acquiring more knowledge on nutrition and wellness and a training certificate, especially one provided by an established institution of learning, you'll gain credibility and perhaps a stronger sense of professionalism. You will also likely gain confidence as you discover what it takes to stay compliant within the specific regulatory environment for supplements."

Upon successful completion of this 45-hour, university-level program, participants will not only gain confidence and credibility, but they will earn a Certificate of Completion of Training as well as continuing education credit hours. Plus, they can feel good about making a difference in the lives of other students, as, in the spirit of social entrepreneurism, Dr. Prasad has stated that 80% of the proceeds from this class will be used to fund scholarships for the needy and deserving students in the Department of Nutrition and Food Sciences. The rest will support special classes, seminars and material development. It's a real win for all involved.

For more details on this course and to sign up for future "Nutrition and Personal Health Coaching" classes, go to TWU.edu. The next official enrollment will begin February 10; new classes will be created as enrolled students reach 25 members.
