Alpha-lipoic acid is a vitamin-like chemical called an antioxidant. Yeast, liver, kidney, spinach, broccoli, and potatoes are good sources of alpha-lipoic acid. It is also made in the laboratory for use as medicine.
Alpha-lipoic acid is most commonly taken by mouth for diabetes and nerve-related symptoms of diabetes including burning, pain, and numbness in the legs and arms. It is also given as an injection into the vein (by IV) for these same uses. High doses of alpha-lipoic acid are approved in Germany for the treatment of these nerve-related symptoms.
How does it work?
Alpha-lipoic acid seems to help prevent certain kinds of cell damage in the body, and also restores vitamin levels such as vitamin E and vitamin C. There is also evidence that alpha-lipoic acid can improve the function and conduction of neurons in diabetes.
Alpha-lipoic acid is used in the body to break down carbohydrates and to make energy for the other organs in the body.
