What is the NSF Certified for Sport® Program?


The NSF Certified for Sport® Program builds on NSF’s expertise in the areas of dietary supplements and functional foods.

To meet the growing demands of athletes, coaches and all those concerned about banned substances in sports supplements, NSF International created the NSF Certified for Sport® Program. This NSF program is a focused solution designed to minimize the risk that a dietary supplement or sports nutrition product contains banned substances.The program certifies that participating manufacturers of sports supplements have met NSF’s stringent independent certification process guidelines, which were developed through a consensus process involving regulatory, industry, and consumer groups. A key component of this program is a specially designed NSF Mark on each product label to show athletes, coaches and consumers that a sports supplement has met NSF’s comprehensive program guidelines.

The NSF Certified for Sport® Program goes beyond the standard NSF certification process to provide additional key preventive measures to:

  • Protect against adulteration of products.
  • Verify label claims with product contents.
  • Identify athletic banned substances in the finished product or ingredients.

There’s a reason why Major League Baseball (MLB), the MLB Players’ Association, National Football League (NFL), the NFL Players’ Association, PGA, LPGA, and the Canadian Center for Ethics in Sports have all chosen NSF Certified for Sport® to ensure the products their athletes use are safe. NSF’s Athletic Banned Substances Program is the only comprehensive program designed for participating manufacturers and their products that includes ISO 17025 accredited product testing methods for 144 banned substances, label content confirmation, formulation and label review, production facility and supplier inspections, as well as ongoing monitoring in line with substance prohibitive lists: WADA, NSF ANNNEX A, NFL, MLB, and NCAA.

Certified for Sport® products are elite, and they have the mark to prove it. Look for the NSF Certified for Sport® mark, to be sure the product you are taking is quality certified to be completely free of banned substances.
