NSF® Certified For Sport

FROM THE NSF: To meet the growing demands of athletes, coaches and all those concerned about banned substances in sports supplements, we created the NSF Certified for Sport® program. The program certifies that what is on the label is in the bottle and that the product does not contain unsafe levels of contaminants.


Our scientists screen sports supplements for more than 200 banned or prohibited substances such as narcotics, steroids, stimulants, hormones and other related substances along with diuretics and other masking agents. We also monitor prohibitive lists of substances, such as NSF Annex A, NFL and MLB, on an ongoing basis.


Certification also means that supplement manufacturers and their suppliers have met our stringent independent certification process guidelines, which were developed through a consensus process involving regulatory, sports industry and consumer groups.

Benefits of Certification

The NSF Certified for Sport® Program helps athletes, coaches and trainers make more informed decisions when choosing sports supplements. The program is recognized by the NFL, NFL Players Association, MLB, MLB Players Association, PGA, LPGA and Canadian Centre for Ethics in Sports.


The NSF certification mark on our products helps athletes of all levels buy our supplements with confidence. Certified supplements must meet rigorous standards that include comprehensive lab testing and extensive evaluation of the manufacturing process to ensure contaminated substances or hidden ingredients are not added to a product.


The program protects you:
- Protect against adulteration of products
- Verify label claims against product contents
- Identify athletic banned substances in the finished product or ingredients
