What NSF Certified for Sport Means

NSF® stands for National Sanitation Foundation. NSF® is an independent accredited organization that tests, inspects, and certifies products. NSF® is widely recognized as the “gold standard” organization when it comes to inspecting dietary supplements.

Certified for Sport® is a program created by NSF® to certify that what is on the label is in the bottle, and that the product does not contain unsafe levels of contaminants, banned substances, or masking agents

Benefits of Tested Supplements for Athletes

Tested supplements are important for athletes, especially professional athletes. 

The Certified for Sport® program verifies that products do not contain any of the 280 substances banned by the major athletic organizations. The Certified for Sport® certification is recognized by the United States Anti-Doping Agency (USADA), Major League Baseball (MLB®), and the National Hockey League (NHL®).
