Super Lipoic Acid offers 600 mg of lipoic acid per capsule to support healthy glucose metabolism, nerve health and antioxidant defense. Research suggests that lipoic acid helps to stimulate glucose uptake by increasing the number of GLUT4 glucose transporters on cell membranes, which provides support for healthy glucose metabolism. As an antioxidant in both its oxidized and reduced forms, lipoic acid can scavenge free radicals, regenerate endogenous antioxidants (such as glutathione and vitamins C and E), and bind metal ions to reduce metal-induced oxidative damage. This unique water- and fat-soluble antioxidant may also protect pancreatic β-cells from damage due to oxidative stress. Because it supports antioxidant defense using a variety of actions in nearly every part of the cell, it is known as the “universal antioxidant.” Furthermore, its antioxidant effects may be especially important in promoting healthy blood flow in nerves. Multiple clinical trials have demonstrated that daily supplementation with 600 mg of lipoic acid helps maintain nerve comfort and function.
