GUARANTEES

180 Days — no questions asked  –
or your money back — even on empties*

Mannatech figures that if you take enough of the product/products long enough you will notice an improvement in your sense of well being.  To that end they give a 180 day (6 month) money back guarantee on all their products.  This guarantee is extended to empty containers, too. 

What have you got to lose?

NSF Certification

This is a national organization that randomly tests all products as to contents, purity, and manufacturing processes. All of Mannatech’s most popular products are NSF-Certified.

This is done so you, the consumer, are reassured to the quality and content of the products.

Kosher Certification

From Mannatech:  “The kosher symbol has become synonymous with accountability, quality and food safety. Being certified kosher means that we comply with a strict policy of kosher food laws, including cleanliness, purity and quality.”

Powerful statements. Quality and accountability – those are 2 cornerstones of Mannatech and their products.

Our manufacturers follow current Good Manufacturing Practices (GMPs) designed to ensure that proper controls are maintained in the development, production, testing and post-market surveillance of our products.

Miscellaneous

We also have, to date, 17 human clinical trials that have been published, 13 of which were double-blind, placebo-controlled studies — the gold standard for product validation. Instead of just talking about “quality” we go out and achieve it with every product through science, technology, and validation.

It is not required that supplement companies subject their products to any kind of validation – but Mannatech does, even though it is expensive.  

*The Company gives a 180 day 100% guarantee – basically saying if you aren’t satisfied after consuming any of our products for up to 6 months you will receive a full refund, even on EMPTY containers.  (NOTE: Other countries limit the guarantee period. This 180 days is for North America. Check with us.)
