Alpha-lipoic acid (ALA) is a part of coenzymes that are involved in the metabolism of carbohydrates, fats, and proteins. ALA is called the œuniversal antioxidant as it is soluble in both water and fat, therefore is able to work in various parts of the body.  As an antioxidant, it is able to scavenge a variety of free radicals including the highly reactive hydroxyl radical and singlet oxygen.  ALA also has the ability to extend the activity of vitamin C and vitamin E as well as regenerate the powerful antioxidants C Q10 and glutathione.  Studies show ALA is a powerful antioxidant that can help protect healthy cell function.  Scientific studies show alpha lipoic acid helps support glucose metabolism, as well as normal, healthy liver function.
