Certified Banned Substance Listing and Approved Supplements Under the Major League Baseball Collective Bargaining Agreement

Ever wonder why baseball players always run afoul of the new drug testing policy and why they claim that they didn't know that a substance was banned? Well, it might be because the list of approved supplements is complicated. Maybe its because I'm not a gym rat myself and don't take supplements, but you basically have to be a scientist to even understand what half of these substances are. The listing of acceptable substances is put out by the National Sanitation Foundation, which changed its name to NSF International in 1990. A listing of the NSF-Approved Supplements can be found here. The entire major league baseball collective bargaining agreement can be found here. The Joint Drug Agreement can be found here.
