The Food and Drug Administration is warning consumers that three weight loss supplements sold online and in some retail stores contain dangerous pharmaceutical ingredients hidden from consumers, and should be thrown away.
The supplements-- called LX1, Mezo, and Best Line Suplemento Alimenticio-- are part of a growing trend of dietary supplements sold for weight loss and sexual enhancement, usually advertised as "herbal" or "all natural," which really contain pharmaceutical ingredients.
According to FDA testing, LX1 contains undeclared DMAA, also known as 1,3-dimethylamylamine, methylhexanamine or geranium extract. DMAA, an amphetamine derivative, is an illegal ingredient often sold in products that claim to boost energy, burn fat or build muscle. It can "can elevate blood pressure and lead to cardiovascular problems ranging from shortness of breath and tightening in the chest to heart attack,"according to the FDA.
