Alpha lipoic acid (ALA) and thioctic acid is an organosulfur compound derived from octanoic acid. ALA is made in animals normally, and is essential for aerobic metabolism. It is also manufactured and is available as a dietary supplement in some countries where it is marketed as an antioxidant, and is available as a drug in other countries. Lipoic acid is a vitamin drugs, limited physical activity in its dextral, basically no physical activity in its Lipoic acid,and no side effects. It is always used for acute and chronic hepatitis, liver cirrhosis, hepatic coma,fatty liver, diabetes, Alzheimer's disease ,and applies as an antioxidant health products.
