Look for the NSF Certified for Sport® Mark

If you use a dietary supplement that bears the NSF Certified for Sport® mark, you can be confident that its contents were thoroughly tested by one of the most respected certifiers in the world. With so many choices on the market, it pays to be cautious. Do your research and look for the Certified for Sport® mark on products.

What the Certified for Sport® Mark Means

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 to choose.

That’s why NSF facilitated the development and maintains the nation’s first truly independent testing standard and product certification program strictly for dietary supplements, NSF/ANSI 173. The Certified for Sport® program builds on that dietary supplements standard and helps athletes make safer decisions when choosing sports supplements.

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.

What Does it Take to be NSF Certified for Sport®

There are numerous quality components of the Certified for Sport® certification program:
  • The product is manufactured at a facility that meets current GMP requirements and audited annually for quality and safety by NSF.
  • Toxicological review of the label to make sure all ingredients are allowed to be in a dietary supplement and that the amount of each ingredient does not exceed typical use levels established by NSF.
  • The product and label are tested to verify product formulation and label claims to be sure that what’s on the label is in the product. Then chemical and contaminant testing is conducted to make sure there are no potentially harmful levels of specific contaminants, pesticides, heavy metals and more.
  • Products are tested for more than 280+ substances which are banned by major athletic organizations and anti-doping associations.
