Home -> Shop By Store -> Alpha Lipoic AcidAlpha Lipoic AcidWhat Is It?In the late 1980s, scientists realized that alpha-lipoic acid, a compound initially classified as a vitamin when it was discovered three decades earlier, possessed potent antioxidant properties that could prevent healthy cells from getting damaged by unstable oxygen molecules called free radicals. In fact, this vitaminlike compound has proved to be many times more potent than such old guard antioxidants as vitamins C and E. As a perk, it even recycles C and E (as well as other antioxidants), enhancing their effectiveness. Because it dissolves in both water and fat, this so-called "universal antioxidant" is able to scavenge more wayward free-radical cells than most antioxidants, the majority of which tend to dissolve in either fat or water but not both. Where is it found? The body makes small amounts of alpha lipoic acid. There is only limited knowledge about the food sources of this nutrient. However, foods that contain mitochondria (a specialized component of cells), such as red meats, are believed to provide the most alpha lipoic acid. Supplements are also available. Health Benefits In addition to functioning as an antioxidant, this hard-working nutrient assists the B vitamins in producing energy from the proteins, carbohydrates, and fats consumed through foods. Intravenous forms of alpha-lipoic acid are administered in hospitals to treat cases of acute mushroom poisoning and for other cases of acute poisoning that affect the liver. How much is usually taken? The amount of alpha lipoic acid used in research to improve diabetic neuropathies is 800 mg per day and 150 mg per day for glaucoma. However, much lower amounts, such as 20–50 mg per day, are recommended by some doctors for general antioxidant protection, although there is no clear evidence that such general use has any benefit. Side effects or interactions Side effects with alpha lipoic acid are rare but can include skin rash and the potential of hypoglycemia in diabetic patients. People who may be deficient in vitamin B1 (such as alcoholics) should take vitamin B1 along with alpha lipoic acid supplements. Chronic administration of alpha lipoic acid in animals has interfered with the actions of the vitamin, biotin. |
