Alpha Lipoic Acid

ALA, alpha-lipoic acid, TA, thioctic acid

General description

Alpha lipoic acid (ALA) is an antioxidant. It is quickly absorbed from the gastrointestinal tract. It dissolves in both water and fat in the body. 

Demonstrated uses

The main use for ALA is to treat diabetic neuropathy. Neuropathy causes sensory changes. These include stinging, burning, pain, and numbness in areas of the skin.

Several small studies have also shown that ALA can help to increase insulin sensitivity. It can lower blood sugar levels in people with diabetes. More research is needed to confirm this. 

ALA is a potent antioxidant. This function may protect nerve tissue from damage. Conditions such as diabetes may be helped by antioxidants such as ALA.

Claims

Doses of ALA range from 200 to 800 mg per day. There is no evidence for a specific dose.
