Late in April, the FDA issued a warning to consumers to stop taking the Hydoxycut line of weight loss products, which have been associated with a number of serious adverse effects including liver and kidney failure. Hydroxycut products are probably the best known weight loss supplements and are sold in national chain stores including GNC and Vitamin Shoppe as pills, drinks, and powders. They are promoted as a way to increase energy, burn calories, and control appetite. Although the manufacturer, Iovate Health Services, has voluntarily withdrawn 14 products, the FDA urges consumers who have already purchased them to throw them away.
The FDA has expanded to 72 the number of weight loss dietary supplements that are tainted with a number of undeclared active pharmaceutical agents. You can find the full list of these products by going to the FDA Web site.
