Alpha-lipoic acid (also known as lipoic acid, thioctic acid, or ALA) is an antioxidant that is made by the body and is found in every cell. The main function of Alpha Lipoic Acid is to increase the body's production of glutathione, which helps dissolve toxic substances in the liver. Alpha-lipoic acid is both fat- and water-soluble. That means it can work throughout the body. Alpha lipoic acid supports healthy glucose uptake and helps to maintain healthy glucose utilization.
