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

ALA is frequently used to treat diabetic neuropathy. This is a sensory change that includes stinging, burning, pain, and numbness in parts of the skin. ALA hasn't been scientifically proven to be helpful in all cases of neuropathy. However, some studies have indicated its helpfulness in mild to moderate cases. It is used by many people with neuropathy. Research continues to be in progress to evaluate ALA's effectiveness.

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

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

Claims
