COPPELL, TEXAS November 9, 2009 - Mannatech, Incorporated (NASDAQ - MTEX), a global pioneer in the development of high-quality health, weight and fitness, and skin care solutions based on nutritional science, announced today their newest product, PhytoBurst™ Nutritional Chews. PhytoBurst soft chews are convenient, tasty lemon or mixed-berry-flavored supplements that support the modern diet with balanced nutrition from vitamins, minerals, phytonutrients and antioxidants. 
PhytoBurst nutritional chews:

• Support the immune system*
• Help keep energy levels going*
• Include important antioxidant support from broccoli, cranberry, grape and rutin*
• Contain natural and food-sourced ingredients
• Are suitable for vegetarians

With today’s hectic lifestyle and the frenzy of the holidays fast-approaching, it can be difficult to maintain proper nutrition on-the-go. These portable chews come in a re-sealable pouch and are ideal for tossing in a gym bag, lunch sack or purse. PhytoBurst soft chews are natural, suitable for the entire family and can be used before a workout, during long periods of activity, while participating in sports or between meals.

“These nutritional chews are an excellent addition to our already outstanding lineup of wellness products,” Dr. Robert Sinnott, chief science officer for Mannatech said. “We believe that because the unique combination of vitamin and mineral blends and phytonutrients found in PhytoBurst soft chews come directly from plant and food sources, our bodies will receive the maximum nutritional benefit from the product. We also feel that the ease with which you can take PhytoBurst soft chews; on the go, without even the need of a glass of water, will help people to maintain their good health in their busy daily lives.”

Additionally, PhytoBurst nutritional chews benefit from Mannatech’s Real Food TechnologySM solutions which use food-sourced and plant-based ingredients for the most useful results in the human body. Along with nutrients sourced from broccoli, cranberry and grape, one serving of two PhytoBurst nutritional chews contain as much Vitamin A as 2.5 fresh apricots and as much Vitamin D as 4 cups of milk (vitamin D) to support your diet with balanced nutrition.

“One of the things that I love about working with Mannatech is that they are always on the cutting edge of technology” said Merri-jo Hillaker, a Silver Presidential Mannatech Associate. “By putting the essential vitamins and nutrients that we need into a flavorful, portable chew, we can offer a unique alternative to your typical supplement. With the PhytoBurst nutritional chews, you really taste and experience the goodness that you’re getting.”
