NSF Supplement Certification

  How Supplements Become NSF Certified

NSF certifies products against NSF/ANSI 173, the only American National Standard that establishes requirements for the ingredients in dietary and nutritional supplements. There are three main components of the NSF dietary supplements certification program:

• Label claim review to certify  that what’s on the label is in the bottle
• Toxicology review to certify product formulation (we don’t test for efficacy)
• Contaminant review to ensure the product contains no  undeclared ingredients or unacceptable levels of contaminants
