Supplements aren’t reviewed for safety and effectiveness, but disclaimers about health benefits are required on products.

The Food and Drug Administration is considering a rule change that would cut back on how often dietary supplement warnings must appear on packaging, a move experts say could make them easier to miss.

Unlike prescription drugs, the FDA doesn’t review dietary supplements for safety and effectiveness before they hit the market.

A 1994 federal law requires supplement companies to include a disclaimer when they make health claims like “supports immune health” or “promotes heart health” or better memory. According to the law, next to promises about benefits, the packaging must display in boldface type: “This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.”
