Alpha Lipoic Acid Supplement Guide: What the Trials Show and Where to Be Careful
Alpha-lipoic acid has trials in diabetic neuropathy with mixed results: a 5-week trial improved symptom scores, a 4-year trial missed its main goal, and a 2024 Cochrane review found little or no effect at six months. It can lower blood sugar, so ask your provider first.
