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 satisfaction guarantee on all their products.
This guarantee is extended to empty containers, too.
What have you got to lose?
This is a national organization that randomly tests all products as to contents, purity, and manufacturing processes. All of Mannatech’s most popular products have been NSF-Certified.
This is done so you, the consumer, are reassured to the quality and content of the products.
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.
Some Other Labels:
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 an expensive process.
