No organization can guarantee the safety, efficacy or non-prohibited status of a dietary supplement.
Due to the current regulatory framework, the Food and Drug Administration (FDA) does not evaluate dietary supplement products prior to them being brought to the market.
As such, it is very important that athletes and athlete support personnel are aware of the risks associated with taking dietary supplements.
USADA has created Supplement Connect as an online resource to help athletes and athlete support personnel, realize the concerns surrounding the use of dietary supplements, recognize risk, and reduce the risk of testing positive or experiencing health problems if an athlete chooses to use supplements.

While there is no way to be completely sure about the safety of supplements, there are some warning signs you can learn to recognize when it comes to identifying risky supplements.

If athletes to use supplements despite the known 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.
Using an NSF Certified for Sport ® product significantly reduces, but does not necessarily eliminate, the chance of testing positive and being sanctioned. Under the rules, if an athlete tests positive and establishes the source as a contaminated NSF Certified for Sport ® product, the athlete could get a much-reduced sanction, but there likely would still be a consequence.
