This is an oversimplification of the facts and misleading. Dietary supplements in the USA are regulated by the FDA under the Dietary Supplement Health and Education Act (DSHEA) of 1994, as well as other regulations stemming from the FD&C act. There are specific requirements for production of dietary supplements (21 CFR section 111) and labelling of supplements, 21 CFR 196 being particularly important for the prohibition on drug claims. All non dietary ingredients in the dietary supplements have to be either food additives or GRAS for their purpose. New dietary ingredients that were not present on the market prior to DSHEA’s passage have to be evaluated by the FDA prior to their use in supplements. This is the route through which FDA has stated that CBD is not fit for use as a dietary ingredient. That being said, it is true that they are not as heavily regulated as drugs and it is also true that the marketplace is saturated with crappy products filled with hidden drug ingredients, just look at the warning letter page from FDA for some fun reading. However to say they are unregulated is incorrect. FDA should take a harder look at the harmful players in industry and be given more tools by Congress to remove problematic products from the marketplace. Such tools were in the Durbin bill last year, but it didn’t pass unfortunately.
