FDA role in regulating supplements
FDA requires supplement production to meet quality standards; manufacturers report all serious dietary supplement adverse events to the FDA -supplements often use structure function claims and dosages are not standardized
Health Claims
-legally defined and regulated by the FDA (must be approved before labeling) -product must not exceed specific levels for fat, saturated fat, trans fat, cholesterol, sodium -product must contain at least 10% of at least one of the following: Vitamin A, C, protein, fiber, calcium, iron -Ex. Suppresses appetite to treat obesity
Functional Claims
-offer the possibility that food may improve or support body function, used primarily by supplement manufacturers -not evaluated by the FDA; not intended to diagnose, treat, cure, or prevent a disease -does not require a disclaimer -Ex. Suppresses appetite to aid weight loss
