NSF® International is a Nonprofit Organization based in Ann Arbor, MI and has been a Recognized Global Leader since 1944. The testing process consists of testing products to ensure they meet label claims and standards (which are more rigorous and difficult than standard FDA cGMP requirements), inspecting/auditing cGMP facilities, and certifying products, components, ingredients, and equipment.

The NSF® Contents Tested & Certified mark on our products is your assurance that the product has been tested by one of the most respected independent certification organizations in existence today. NSF® independently certifies a product meets label claim for its nutrients and is tested to be safe from harmful contaminants. Wiley’s Finest is proud to offer a line of exceptional quality supplements that stand out as an industry leader in third party GMP certification and testing.
