Why do people take Alpha Lipoic Acid?

We have strong evidence that Alpha Lipoic Acid supplements help with type 2 diabetes. Several studies have found that they can improve insulin resistance.
Studies also found that Alpha Lipoic Acid supplements can help with neuropathy -- nerve damage -- caused by diabetes or cancer treatment. They seem to reduce symptoms like pain, tingling, and prickling in the feet and legs. It may also help protect the retina from some of the damage that can occur in people with diabetes.
Although these uses are promising, diabetes and cancer obviously need proper medical treatment. So don't treat yourself on your own with supplements. Instead, see your doctor and ask if Alpha Lipoic Acid might help.
