Alpha lipoic acid is a powerful antioxidant. It is a fat-soluable, vitamin-like substance that works along with certain B vitamins in the metabolism of carbohydrates and other nutrients to produce energy. It is capable of fighting free radicals in both aqueous (watery) and lipid (fatty) environments.
Alpha lipoic acid (ALA) has been used as a treatment for multiple ailments. In addition to being a powerful antioxidant, ALA is a blood glucose regulator and is significantly involved in the energy production of cells. It has also been shown to be an effective means of glutathione replenishment. R-fraction stabilized alpha lipoic acid (R-ALA) is the active form used by the body.
Recently, scientists have developed an even more highly stabilized and purified form of R-ALA, which will be more bio-available than the original R-ALA.
