Lipoic acid is a naturally occurring compound that plays a crucial role in energy metabolism within the body. It acts as an antioxidant, helping to neutralize harmful free radicals and protect cells from damage. Lipoic acid is found in small amounts in foods such as spinach, broccoli, and potatoes, and is also available as a dietary supplement. In addition to its antioxidant properties, lipoic acid is involved in the conversion of glucose into energy. It supports the function of other antioxidants, such as vitamin C and vitamin E, enhancing their effectiveness. Research suggests that lipoic acid may have potential benefits for conditions like diabetes and neuropathy.
