Supports liver detoxification.

This vitamin-like nutrient helps neutralize free radicals by enhancing and restoring other antioxidants, such as vitamins C and E, and glutathione.

Alpha-lipoic acid supports the liver in its detoxification efforts, thus helping to protect tissues against damage by excessive iron or copper, or toxic heavy metals such as arsenic, cadmium, lead, and mercury.
