What Are Alpha Lipoic Acid Supplements?
Alpha lipoic acid (ALA) is an antioxidant and a fatty acid that is naturally present in every cell of the body. It is also sometimes called thioctic acid or lipoic acid. While the body naturally manufactures alpha lipoic acid, additional ALA can be obtained through dietary sources. Organ meats, red meats, and yeast contain this substance. Some people may also take alpha lipoic acid supplements, or a doctor may administer the compound in an injection.
