TwinLab Alpha Lipoic Acid contains 50 mg of sulfur-based Alpha Lipoic Acid supplementation for overall immune support. Alpha Lipoic Acid is a water-soluble, fat-soluble compound which functions primarily as a blood sugar converter for cell fuel production. Studies have shown that Alpha Lipoic Acid may help promote healthy blood sugar levels in the body. It is also a powerful antioxidant that stimulates other antioxidants in the body such as Vitamins C, E, and Glutathione. Unlike other antioxidants, Alpha Lipoic Acid has the ability to pass through blood-brain barriers which helps protect the brain against toxins and free radicals. Due to these properties, TwinLab Alpha Lipoic Acid may help prevent the onset of premature aging and reduce the risks of chronic diseases.
