  Mannatech Announces Publication of Ambrotose Complex Powder Trial

            Study finds that Ambrotose Complex can improve memory

COPPELL, Texas -- February 12, 2014

Mannatech, Incorporated  (NASDAQ: MTEX), the founder of the M5M^SM (Mission 5
Million^SM) social entrepreneurial movement, the pioneer of glycobiology and
the leading innovator of naturally-sourced supplements based on Real Food
Technology^® solutions, announced today the publication of a randomized,
double-blind, placebo-controlled human clinical trial showing that intake of a
single serving of Ambrotose^® complex powder can improve memory.*^1

In this study, 73 healthy, mentally fatigued middle-aged adults taking
Ambrotose complex experienced statistically significant improvements in their
performance on a battery of tests assessing cognitive function, without
affecting blood glucose levels.* The study was led by Dr. Talitha Best, a
post-doctoral research fellow at the Nutritional Physiology Research Centre,
Sansom Institute for Health Research, University of South Australia (UniSA).**

“While the majority of older Americans take dietary supplements to support
overall wellness and healthy aging, they are aware of age-related memory
problems but haven’t found a supplement that they believe will help,”
commented Dr. Robert Sinnott, Mannatech’s CEO and Chief Science Officer. “This
study makes it clear that consumers have a product, now backed by three
double-blind, placebo-controlled trials, that can provide significant
cognitive benefits, both after a single serving^1 and long-term intake.” ^ 2,

While neuropsychological testing indicates that declines in some aspects of
memory function can be detectable as early as one’s 20s and 30s, most people
start noticing memory issues about age 50 and thereafter. Given the
rapidly-growing number of adults aged 65 and older in the developed
world—seniors comprise over 13% of the population in the U.S., Canada and
Australia, and 25% of the population in Japan—the need for validated, safe
dietary supplements to support healthy cognitive function, a cornerstone of
the quality of life, is exploding.

“A healthy lifestyle —one that includes exercise, a healthy diet, no more than
moderate alcohol intake, staying mentally active, managing stress, getting
adequate sleep, not smoking and staying socially active—can help optimize
cognitive function throughout life,” continued Dr. Sinnott. “Our patented,
clinically validated Ambrotose products, which have been safely consumed for
almost 20 years, are a great choice for people who want to get the most out of
their golden years.”
