Alpha lipoic acid (ALA) is an antioxidant that is produced in the human body. There are good food sources of ALA which include spinach, broccoli, beef, yeast (particularly Brewer's yeast), and certain organ meats (such as the kidney and heart). Usually, people can not ingest sufficient amount to exert its benefits. In the mitochondria, ALA can act both as an antioxidant, capable of recycling other antioxidant nutrients such as vitamin C and vitamin E, and as a coenzyme for key metabolic enzymes involved in energy production. It is important for growth, helps to prevent cell damage, and helps body gets rid of harmful substances. ALA also raises glutathione level within cells. Glutathione is critical for neural function, and aids in glycolysis, the first stages of breaking down carbohydrates for energy. Research suggests ALA can speed the removal of blood glucose level thus benefits diabetes. ALA may help reduce pain, burning, itching, tingling, and numbness in people who have nerve damage (called peripheral neuropathy ) cased by diabetes. ALA has been used for years for this purpose in Europe. ALA also benefits liver health, brain function and skincare due to its both water and oil soluble characteristics in cell.
