How Does a Substance Become Prohibited?

Under the World Anti-Doping Code, the World Anti-Doping Agency (WADA) issues an annual List of Prohibited Substances and Methods, known as the Prohibited List, which is one of five International Standards. WADA reviews scientific and medical research, while also consulting with others in the anti-doping community, to make annual updates to the Prohibited List.

Medications vs. Supplements

Given that they are both used for health purposes, it would be easy to assume that medications and supplements are regulated the same way and produced to the same standards, but unfortunately this is not the case. Unlike medications, supplements are regulated post-market, which means that no regulatory body evaluates the contents or safety of supplements before they are sold to consumers.
