Not only "exists", but has managed to fight off almost any form of regulation whatsoever. There are no regulations requiring they disclose everything that is in the supplement (so a vitamin C supplement can contain Vitamin E, at any concentration, with no mention of it on the label), or that the label have correct concentration information, or be free from substances known to be toxic to humans. I think the only thing they're required to do is meet manufacturing facility standards. Labdoor and others have found high levels of Arsenic and other poisonous materials in protein powder. Protein powder! Which apparently gets to skip all FDA regulation by being called a "supplement."
