NSF Also Certifies That Mannatech's Manufacturer Meets Good                         Manufacturing Practices COPPELL, Texas--(BUSINESS WIRE)--Mannatech, Incorporated (NASDAQ: 
MTEX - 
News) today announced that the purity of Mannatech
’s 
PLUS™        and 
Ambrotose        AO® glyconutritional supplements has been certified to show they meet their label claims for ingredients and purity by 
NSF        International, an independent, accredited testing organization. In        June, Mannatech received certifications from NSF for its Ambrotose
®        and Advanced Ambrotose
™ products.
The products were certified according to the NSF/ANSI 173 Dietary        Supplement Standard
—the only American National        Standard for dietary supplements. 
Mannatech        intends to carry the NSF certification mark on the supplements
’        labels and promotional materials to demonstrate compliance.
“Mannatech is committed to pursuing the highest standards of product quality and science. Not only did we earn NSF certification, but we ensure all our manufacturing partners adhere to Good Manufacturing Practices (GMPs), our industry’s        standards for ensuring high quality products,”        said Marika Berkley, vice president of global regulatory affairs and        quality assurance for Mannatech. “Customers        need to know that our products always meet these high standards and that        they will never be compromised.”
NSF International—a not-for-profit, public        health certification organization—ensures a        product’s label reflects the contents of the supplement, that all ingredients are openly disclosed on the label and that the product’s purity is acceptable. Additionally, NSF assesses each manufacturing site to ensure it complies with GMPs; NSF will not certify a product unless the manufacturer meets all the rigorous audit requirements.
“By obtaining certification for two additional products, Mannatech continues to demonstrate its dedication and commitment to excellence,” said Ed        Wyszumiala, general manager of NSF’s dietary        supplements programs.
Mannatech will continue working with NSF to certify additional products        in Mannatech’s portfolio.
