The federal Food and Drug Administration was put in place to protect consumers from faulty products that fall under the food or drug categories. Unfortunately, these categories do not extend to dietary supplements.
While a dietary supplement can act like a drug, it is not one. It is also not technically a food. This means that the FDA cannot regulate any dietary supplements, and the products enter the market regardless of whether or not they have been tested for safety.
