Supplement 411 is USADA’s dietary supplement safety education and awareness resource. The reality is that the use of dietary supplements can be risky, and that awareness and caution must be exercised when considering their use. If you’re looking for a quick answer, then USADA recommends you use only supplements certified by NSF Certified for Sport® as the way to best reduce your risk.

While no resource can protect you completely, Supplement 411 will help you gain a better understanding of the dietary supplement issue by covering the topics below:

NSF supplement risk gauge

Dietary supplements are regulated in a post-market fashion, which means that no regulatory body approves the accuracy of the label or safety of the contents before they are sold to consumers. As such, no dietary supplement can be guaranteed to be 100 percent risk-free. If athletes choose to use supplements despite the risks, USADA has always recommended that athletes use only dietary supplements that have been certified by a third-party program that tests for substances prohibited in sport. USADA currently recognizes NSF Certified for Sport® as the program best suited for athletes to reduce the risk from supplements.
