GENERAL DESCRIPTION: Alpha lipoic acid is a sulfur-containing fatty acid found inside each and every body cell. Lipoic acid has a key role in the metabolism as it helps to convert glucose into cellular energy. ROLE FOR ANTI-AGING: Alpha lipoic acid is a potent antioxidant. Unlike other antioxidants, which work only in water or fatty tissues, lipoic acid can function in both water and fat.
GENERAL DESCRIPTION:
Alpha lipoic acid is a sulfur-containing fatty acid found inside each and every body cell. Lipoic acid has a key role in the metabolism as it helps to convert glucose into cellular energy.
ROLE FOR ANTI-AGING:
Alpha lipoic acid is a potent antioxidant. Unlike other antioxidants, which work only in water or fatty tissues, lipoic acid can function in both water and fat. It is also thought to help recycle other antioxidants such as vitamin C and vitamin E. Because lipoic acid is fat-soluble, it can help prevent free radical damage from occurring inside nerve cells. Alpha lipoic acid’s antioxidant properties mean that it can help to protect against diseases caused by oxidative damage, for example cancer and cardiovascular disease. It also has several potential benefits for diabetics as it enhances glucose uptake in noninsulin dependent diabetes, inhibits glycosylation, and improves diabetic neuropathy. Some research has also indicated that it can improve vision in patients with glaucoma. In vitro studies have shown that alpha lipoic acid can inhibit replication of the HIV virus, however this has not been replicated in invivo research.
DEFICIENCY SYMPTOMS:
Humans are not known to develop deficiencies of alpha lipoic acid as the body manufactures it to demand.
THERAPEUTIC DAILY AMOUNT:
The usual dose for antioxidant purposes is 20-50mg per day, however doses between 300 and 600mg can be given to treat diabetic neuropathies.
MAXIMUM SAFE LEVEL:
Alpha Lipoic acid appears to have no significant side effects at daily dosages up to 1,800 mg.
SIDE EFFECTS/CONTRAINDICATIONS: None known. Pregnant women and people suffering from any type of medical condition should consult their doctor before taking alpha lipoic acid.
