Can taking a nutritional supplement trigger a positive test?
Unfortunately, due to the lack of regulation present in today’s nutritional supplement marketplace, including the existence of unscrupulous, rogue supplement manufactures, USADA is unable to provide direction or guidance as to which nutritional supplements are safe, and which contain prohibited substances. USADA is currently working with the NFL, MLB, NBA, NHL, USOC and other national sports and health organizations to eliminate this uncertainty in the marketplace. The effort, called “Supplement Safety Now” includes media outreach and grassroots mobilization. USADA is also in the process of launching an online portal specifically dedicated to the questions and issues surrounding supplements.
