Australian Scientist Wins Researchers in Business Project Funding

Mannatech, Incorporated (NASDAQ: MTEX), the leading innovator and provider of nutritional supplements and skin care products based on Real Food Technology^® solutions, announced today that the Australian government has granted Dr. Talitha Best a 12-month Researchers in Business (RiB) grant to help develop research on Mannatech’s glyconutritional products.

The $10 million RiB program is part of Enterprise Connect, an initiative within the Australian government’s Department of Innovation, Industry, Science and Research. The program is designed to accelerate industry innovation and competitiveness by connecting university and public agency researchers with businesses that wish to develop new ideas with commercial potential. RiB initiatives are destined to play an important role in enhancing the transfer of university intellectual capital into practical business applications and to stimulate the dissemination of industry knowledge back into the research community. Exciting innovation is expected to flow from breaking down the cultural divide between academia and business.

"Mannatech is pleased to be collaborating with the government of Australia, the University of South Australia (UniSA) and Dr. Talitha Best on this project,” said Dr. Robert Sinnott, co-CEO and chief science officer of Mannatech. "Australia has a wonderful business climate, and by virtue of its geographical location, it is a key interface between the Western world and Asia. Australia is a perfect place to develop innovation that will carry companies forward for years to come.”

For more than six years, Dr. Best, a post-doctoral research fellow at the Nutritional Physiology Research Centre, UniSA, and the Brain Sciences Institute, Swinburne University of Technology, has been investigating the impact of dietary saccharides on human brain function. She has presented her findings at numerous scientific conferences and has shown, in two randomized, double-blind, placebo-controlled human clinical trials, that intake of Mannatech’s saccharide supplement, Ambrotose^® complex, can provide both immediate and long-term improvements in memory, cognition and well-being (1)^†,(2)^‡*.

"With Australia’s reputation as an important contributor to groundbreaking clinical trial glyconutrition research, this grant is both apposite and timely,” said George Howden, general manager, Mannatech Australia. "The research and development derived from this project will serve as a catalyst for uncovering new discoveries regarding the impact of glyconutrients on health, thus driving the wellness industry to new heights.”
