The Food and Drug Administration (FDA) regulates dietary supplements, including those promoted for weight loss. Like other dietary supplements, weight-loss supplements differ from over-the-counter or prescription drugs in that the FDA does not classify them as drugs.

Products containing hidden drugs are also sometimes falsely marketed as dietary supplements, putting consumers at even greater risk.
