Mannatech, Incorporated (NASDAQ: MTEX), a leading developer and provider of dietary supplements and skin care solutions, announces the launch of its new fat-loss product OsoLeanâ„¢ powder. OsoLeanâ„¢ whey protein supplement is an all-natural powder product that mixes with a variety of food and beverages so consumers can easily add it to any weight and fitness program.

Mannatech also launched the OsoLeanâ„¢ Challenge among its independent Associates, who will track their waist circumference in inches while using OsoLeanâ„¢ powder, in conjunction with the OsoLeanâ„¢ Plan and exercise, during an eight week period between Sept. 4 and Dec. 31, 2008.* A number of Mannatech executives have also joined the challenge, sparking some friendly competition with Associates.

In a clinical study, OsoLeanâ„¢ powder has been shown to help target fat loss and spare lean muscle when combined with the OsoLeanâ„¢ Plan and proper exercise.* Additionally, whey protein and calcium from milk have been shown to promote fat loss while maintaining muscle in combination with a reduced-calorie diet and proper exercise.

“The launch of OsoLean™ powder is yet another milestone for our company,” said Dr. Robert Sinnott, chief science officer and senior vice president of Mannatech. “With this newest offering, we are on the forefront of protein peptide technologies that deliver outstanding results. It is an ideal dietary supplement product because it offers the consumer both convenience and the latest application of science to specifically target fat loss while maintaining lean muscle mass.”*
