Alpha lipoic acid is a perfect antioxidant as it is both fat soluble and water soluble. As a result, alpha lipoic acid is quickly absorbed by the body and transported via the blood to the cells in our body. Because it is absorbed everywhere in our body, it also offers powerful protection for the brain. Alpha lipoic acid can 'reactivate' other antioxidants and therefore has a nourishing effect on the entire body. Alpha lipoic acid helps release energy from carbohydrates, proteins and fats.
