If a dietary supplement “works” and increases testosterone levels, then it’s prohibited. For these reasons, USADA advises athletes to avoid all products that make performance-enhancing claims and to only use supplements that are certified under the NSF Certified for Sport program. Magnesium is another mineral that has been shown to have a direct relationship with testosterone levels in men. In one study, subjects practicing martial arts were given 10mg of magnesium per kg of body weight.
