NEWS RELEASE

COPPELL, Texas, Jul 07, 2010 (BUSINESS WIRE) --

For the first time in the 25-year history of the International Sport Karate Association (ISKA), the board of directors has certified a global brand as its official health and wellness supplement provider - Dallas-based Mannatech, Incorporated (NASDAQ: MTEX).

Several of the nutritional science leader's products will be the only health supplements on the market to receive an 'ISKA Certified for Elite Athletes' seal featured on its packaging.

"This certification program was developed by ISKA to recognize high-quality dietary supplements. Mannatech was handpicked by ISKA as the only supplement provider for this prestigious program," said Robert A. Sinnott, Ph.D., MNS, co-CEO and chief science officer of Mannatech. "This alliance combines the high standards that ISKA demands of its athletes with those that Mannatech demands of its products."

Established in 1986, ISKA is the world's most recognized sanctioning and regulatory body for competitive martial arts and combat sports with participants from 50 countries worldwide. ISKA and Mannatech's exclusive initial partnership will last until 2012, with an option to renew, and is geared to establish a trusted advocate for personal health and wellness. This joint venture will also introduce Mannatech's catalog of NSF-Certified products and create a real possibility for an additional business-building opportunity for all studio owners nationwide.

The exclusive partnership will be announced at the ISKA's U.S. Open, considered the world's most celebrated martial arts event, July 9 - 10 at the Coronado Springs Resort in Orlando, Fla.

"Mannatech's leadership in the health and wellness industry is second to none," said ISKA President Cory Schafer. "As the governing body for martial arts and our 28,000 studio owners across the country, it is our chief responsibility to surround owners and their students with only the best in health and wellness. We know Mannatech offers the technology for optimum health and wellness we require and are proud of this partnership."

Mannatech, a global pioneer in the development of high-quality health, weight and fitness, and skin care solutions based on nutritional science, has distinguished itself in the emerging glyconutrients market through the development of Ambrotose^(R) complex, the technology for which it holds more than 45 patents in 30 countries.

Chip Townsend, a 5^th degree black belt (or Godan) and 14-time ISKA world breaking champion, understands the importance of healthy supplements and additional resources of income as both a successful studio owner and Team Mannatech^SM athlete, which he has been since 2005.⁺

"This partnership is beneficial as a competitive athlete, a member of Team Mannatech and as an Associate because it brings credibility to our mission of health," said Townsend. "Knowing that Mannatech's products are backed by scientific validation and the addition of ISKA's seal of approval enables me to better educate my students and their families."

Many of Mannatech's products are based on Real Food Technology^(R) solutions, which provide consumers with products that contain standardized levels of natural and plant-sourced nutrients. Food-sourced ingredients are chosen from those scientifically proven to most benefit the human body.

The Mannatech products to be featured with the ISKA seal and sold through participating martial arts and MMA studios across the country include Ambrotose complex and Advanced Ambrotose^(R) product, Ambrotose AO^(R) capsules, BounceBack^(R) capsules, Optimal Support Packets, PhytoMatrix^(R) caplets and PLUS(TM) caplets.

The 37^th annual U.S. Open will be nationally televised on ESPN2 July 23. Consult your local directories for times.
