Ultra Tested.Kirkman's Alpha Lipoic Acid is a powerful and versatile nutrient with antioxidant activity that helps protect the body against free radical damage and, as a result, is a protector of many types of cells and tissues. It also helps increase glutathione production, which supports detoxification processes in the body.Alpha lipoic acid is a nutritient 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 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.Dietary ConsiderationsWheat FreeDairy/ Milk FreeGluten FreeSoy FreeYeast FreeSugar FreeStarch FreePreservative FreeFree of Artificial Colors/FlavorsFish FreeTree Nut FreePeanut FreeServing Size: 1 CapsuleServings Per Container: 90Amount Per Serving:Alpha lipoic acid25 mgOther Ingredients:Microcrystalline cellulose, alpha lipoic acid, silicon dioxide, plant cellulose capsuleSuggested Use: One capsule per day or as directed by a physician.Free of: Sugar, starch, soy, wheat, casein, gluten, milk, corn, preservatives, yeast, gelatin, flavorings, colorings, peanuts, tree nuts or fish.Important: Store in a cool dry place and tightly capped.
