Is 600 mg of alpha-lipoic acid too much?

600 mg is on the high end of common ALA doses; many studies use 300–600 mg. If you are new to ALA, ask your doctor whether to start lower.

Can I take it with diabetes medication?

ALA can lower blood sugar, so combining it with insulin or other glucose-lowering drugs may cause hypoglycemia. Talk to your doctor before adding it.

Take one veggie capsule daily, ideally with a meal. Each capsule supplies 600 mg of ALA.

Our take on the Alpha-Lipoic Acid 600

Doctor's Best Alpha-Lipoic Acid 600 is a vegan capsule supplement delivering 600 mg of ALA per capsule, taken once daily. ALA is a coenzyme involved in glucose metabolism and is called a "universal antioxidant" because it dissolves in both water and fat, and it helps recycle vitamins C and E. The formula is non-GMO, gluten-free and soy-free. At $16.99 at Amazon as of November 4, 2026, it is the best new price among the two stores listing it.
