Hoping to boost your immunity? Keep your brain sharp? Improve your mood? Look no further than the supplement aisle at your local drugstore. At least that’s what supplement makers want you to believe. “Claims, especially structure/function claims, may help sell product,” says NaturalProductsInsider.com. “However, they may also invite regulatory action if improperly phrased or inadequately supported.” But supplement makers needn’t fear. They’ve got plenty of tools at their disposal. Companies can make claims about how a supplement (or food) affects the normal structure or function of the body with little oversight by the Food and Drug Administration, as long as the claims don’t name a disease or promise to treat a condition.
