NSF Certified for Sport® Certification


NSF Certified for Sport® CertificationThe NSF Certified for Sport® program was created to meet the growing demands of athletes, coaches and all those concerned about banned substances in sports supplements. The program certifies that what is on the label is in the bottle and that the product does not contain unsafe levels of contaminants, prohibited substances and masking agents.

Our scientists screen sports supplements for more than 265 banned or prohibited substances including:

  • Narcotics
  • Steroids
  • Stimulants
  • Hormones
  • Related substances along with diuretics and other masking agents

We also monitor prohibitive lists of substances, such as NSF Annex B, NFL and MLB, on an ongoing basis.

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