The Federal Food, Drug, and Cosmetic Act preempted plaintiff’s claim that defendant’s label on a dietary supplement was misleading in naming the supplement “Glucosamine Sulfate” when its active ingredient was glucosamine hydrochloride. The majority held that the FDA’s labeling regulations governed the product name as well as the information in the nutrition facts panel and that following those regulations, the product was properly named. State law could not require that the product be given a different name.
