The best supplements for nerve pain depend on the cause. Vitamin B12 can reverse nerve damage caused by B12 deficiency if treated early. Alpha-lipoic acid improved diabetic neuropathy symptoms in some trials. Acetyl-L-carnitine has limited evidence. High doses of vitamin B6 over time can cause neuropathy, so avoid mega-dose B-complex products.
