How does a supplement become NSF Certified for Sport®?

The first step is for NSF to inspect and certify each manufacturing facility for Current Good Manufacturing Practices (cGMP). To maintain certification, each facility is audited twice yearly.

The NSF Certified for Sport® mark validates that the supplement contains none of the nearly 300 substances banned from competition by major athletic organizations, such as WADA and USADA.

Once a supplement is manufactured, NSF independently tests every batch before it can be sold to consumers with the NSF Certified for Sport® mark.

The NSF Certified for Sport® program ensures that the supplements you take to optimize your performance at every stage of athletic competition have been independently tested for quality and safety.

A supplement with the NSF Certified for Sport® mark has been independently tested to verify that the ingredients listed on the label are present in the product, in the amounts stated.

Certification by NSF helps both professional and recreational athletes make safer decisions by choosing supplements that are cleaner, safer, and more trustworthy.
