Item 8.01 Other Events.

On September 6, 2007, Mannatech’s Board of Directors decided to resubmit Mannatech’s 2007 Stock Incentive Plan (the “Plan”) to the shareholders for approval at Mannatech’s 2008 annual shareholders’ meeting. The Plan was originally adopted by Mannatech’s Board of Directors on February 20, 2007, and the Plan’s adoption was approved by Mannatech’s shareholders on June 14, 2007. After the favorable vote was received to approve the adoption of the Plan, it was discovered that the number of shares reported as reserved for issuance under existing stock option plans and the number of shares reserved for issuance under outstanding but unexercised awards was incorrectly stated in the Plan and the proxy materials as 1,234,985 and 235,808, respectively, but should have been reported as 224,687 and 1,227,485, respectively. The Board of Directors intends to amend the Plan to correct the referenced numbers and submit the amended Plan to the shareholders for approval at Mannatech’s 2008 annual shareholders’ meeting.

Exhibit 99.1

Mannatech Adds Distinguished Kellogg Professor Robert Blattberg to Board

Appointment follows conclusion of Professor Axford’s five-year tenure on Mannatech Board

Coppell, TX, September 7, 2007 – Mannatech, Inc. (NASDAQ – MTEX) today announced effective September 6, 2007, the addition of Professor Robert Blattberg from Northwestern University’s Kellogg School of Management to the company’s Board of Directors. Blattberg replaces outgoing Board member Professor John Axford who is leaving the Board to focus his efforts on new research initiatives with Mannatech, as well as complete the glyconutritional research under a three-year agreement between St. George’s University of London and Mannatech.

Since 1991, Professor Blattberg has served as the Polk Brothers Distinguished Professor of Retailing and Director for the Center for Retail Management within Northwestern University’s Kellogg School of Management. He is currently on a one-year leave of absence and is a visiting professor at Carnegie Mellon University. Previously, he held the title of the Charles H. Kellstadt Professor of Marketing and served as Director of the Center of Marketing Information Technology for University of Chicago’s Graduate School of Business.

“We are quite pleased to have someone with Professor Blattberg’s knowledge and expertise in global retail marketing join our Board,” said J. Stanley Fredrick, lead director on Mannatech’s Board. “His vast experience and published accomplishments speak volumes about his ability to assist organizations in achieving success through solid marketing strategies and principles.”

Professor Blattberg focuses his research on marketing information technology, database marketing, sales promotions, and retailing. In addition to authoring several books, he has written articles for the Journal of Marketing Research, Management Science, Marketing Science, Econometrica, Journal of Marketing, Journal of Direct Marketing, and other leading academic journals. He has also consulted for leading retailers, such as Sears, Kroger, Rite Aid, and Best Buy.

Fredrick added, “We have been very fortunate to have Professor Axford, an accomplished glycobiologist and physician, serve on our Board of Directors. During his five-year tenure, he helped create and chair the Science Committee within the Board where he provided critical direction and expertise to our R&D program. He also assisted in attracting key scientific talent as evidenced by the addition of Dr. Robert A. Sinnott, senior vice president and chief science officer of R&D in 2005.”

Since 2002, Professor Axford has served as a Class III Director and is Chairman of the Science Committee. Mannatech will continue its ongoing three-year agreement with St. George’s University of London, where Professor Axford is serving as the Principal Investigator of a clinical study on Mannatech’s Ambrotose product.
