What Our Mark Means

Runners at starting line ready to start a race

Given the fast pace at which many dietary supplements enter the marketplace and reports that suggest that some of these products do not actually contain the ingredients or quantities shown on the label, consumers have cause to be concerned. With such a confusing array of information out there, it can be difficult to determine which manufacturers’ products are credible.

That’s why NSF International led the development of the first truly independent testing standard and product certification program strictly for dietary supplements, NSF/ANSI 173.

NSF International’s Certified for Sport® program meets the growing demands of athletes, coaches and all those concerned about banned substances in dietary supplements and functional foods. We verify that these products do not contain unsafe levels of contaminants, prohibited substances or masking agents, and that what is on the label matches what is in the product. By doing so, the Certified for Sport® certification program provides consumers with safer choices when selecting dietary supplements and functional foods.

The Certified for Sport® certification is the only independent third-party certification program recognized by the United States Anti-Doping Agency (USADA), Major League Baseball, the National Hockey League and the Canadian Football League. Certified for Sport® is also recommended by the NFL, NBA, PGA, LPGA, CCES, CPSDA, iNADO, Ironman, NASCAR, Taylor Hooton Foundation and many other organizations seeking to mitigate the risks of contaminated dietary supplements.

MLB logo“MLB Clubs are permitted to only provide and recommend products that are Certified for Sport®, and players are urged to only use these products. NSF has expanded their program to meet the growing needs of our athletes and developed valuable resources to help guide them through the dietary supplement industry.”

– Jon Coyles, Vice President, Drug, Health & Safety Programs, MLB
