Alpha-lipoic acid is a powerful antioxidant because it is water-soluble and fat-soluble, ie it protects the cells in all situations. It fights against free radicals and also helps to regenerate other antioxidants. It has an action on the quality of skin, hair, but also on the muscle fiber and body quality in general.
But the slowing down of cellular aging isn’t the only benefit of ALA. In effect it also stimulates insulin activity and therefore the synthesis of nutrients to the muscles.
