NSF International is a not-for-profit,
non-governmental organization that was founded in 1944 as the National Sanitation Foundation. NSF provides
public health and safety related information to concerned consumers around the world as well as providing
services to manufacturers in over 100 different countries. The NSF logo represents that a product has been
tested to verify label claims as well as to ensure it is free of such contaminants as heavy metals,
microbiologicals and aflatoxins.
The NSF's Certified for Sport program performs the same screening and verification as the standard certification
program with the addition of in-depth screenings that ensure the product does not contain banned or prohibited
substances, thus earning the much more stringent NSF Certified for Sport certification. The NSF Certified for Sport
program performs independent screening tests for over 130 banned metabolites.
This NSF independent review is utilized by Major League Baseball, the MLB Player's Association, the NFL, the NFL
Players Association, the PGA, LPGA and the CCES (Canadian Center for Ethics in Sport). These organizations have all
chosen NSF's Certified for Sport program to help verify that the products their athletes use are safe and free of
banned substances. Only NSF offers a comprehensive program designed for participating manufacturers and their
products that includes product testing for banned substances, label content confirmation, formulation and label
review, comprehensive and multi-phase audits of the manufacturing facility, supplier inspections, as well as
ongoing monitoring in line with substance prohibitive lists from the WADA, NFL, and MLB.
