Doctor's Best, Best Alpha-Lipoic Acid 300, 300 mg, 180 Veggie Caps

Alpha lipoic acid (ALA) is a fatty acid that functions like a vitamin, although it is not classified as a vitamin. As a coenzyme, ALA plays an important role in the metabolism of glucose that produces energy in cells. ALA also has antioxidant properties and thus is important for controlling free radicals. Because it is soluble in both water and fat, ALA is sometimes referred to as the universal antioxidant.
