alpha-lipoic acid

“Alpha-lipoic acid” (lipoic acid) — a powerful antioxidant that is readily absorbed and utilized within the cell where it is capable of regenerating glutathione. As such, lipoic acid supplementation results in increased glutathione levels. Lipoic acid is also involved in energy production. Lipoic acid works together with vitamin E and vitamin C to protect the entire cell from oxidative stress.
