Because alpha lipoic acid can protect cells and neurons involved in hormone production, one benefit is it offers protection against diabetes. ALA is considered an effective drug in the treatment of diabetic distal sensory-motor neuropathy, which affects about 50 percent of people with diabetes. (5) In dietary supplement form, ALA seems to help improve insulin sensitivity and might also offer protection against metabolic syndrome — a term given to a cluster of conditions like high blood pressure, cholesterol and body weight. Some evidence also shows that it can help lower blood sugar levels.
ALA is used to help relieve complications and symptoms of diabetes caused by nerve damage, including numbness in the legs and arms, cardiovascular problems, eye-related disorders, pain, and swelling. That’s why it should be part of any diabetic diet plan to treat this common disorder. People who experience peripheral neuropathy as a side effect of diabetes can find relief from pain, burning, itching, tingling and numbness using ALA, although most studies show that high doses in IV form are most effective as opposed to eating ALA-rich foods.
A major benefit of alpha lipoic supplementation in diabetics is the lowered risk for neuropathic complications that affect the heart, since around 25 percent of people with diabetes develop cardiovascular autonomic neuropathy (CAN)
