How are supplements regulated?

The short answer

Loosely. In the United States, the FDA generally does not approve supplements for safety and effectiveness before sale. Manufacturers still have legal responsibilities for labeling, safety, and manufacturing standards, but that is different from premarket drug approval.

Independent testing regularly finds products with too little, too much, or none of the listed ingredient, and sometimes with contaminants or hidden drugs. Protect yourself by buying products that carry a third-party seal such as USP, NSF, or Informed Choice. And tell every doctor what you take. Supplements interact with blood thinners, heart medicines, and anesthesia.
