It also helps increase glutathione production, which supports detoxification processes in the body. Alpha lipoic acid is a nutrition with unique antioxidant activity in that it is both fat- and water-soluble. Other well-known nutrients with antioxidant activity can only function within their soluble media. Because of its dual solubility, alpha lipoic acid can function in both fatty and aqueous parts of a cell and is capable of defending against a wide variety of invading free radicals. Alpha lipoic acid can enter all parts of a nerve cell and also cross the blood-brain barrier and protect cells. Alpha lipoic acid is found naturally in foods such as spinach, broccoli, tomatoes, liver, heart and animal muscle tissue. Its bioavailability from food may be limited, however, because it is bound to a protein called “lipoyllysine.” Preliminary research suggests that the alpha lipoic acid found in supplements may be more biologically active than when bound to this protein in food.
