Alpha Lipoic Acid

Alpha lipoic acid (ALA) is an antioxidant your body makes in small amounts and uses to turn food into energy. It is unusual because it works in both water and fat, so it can protect cells throughout the body, and it helps recycle other antioxidants such as vitamins C and E and glutathione. ALA is popular for nerve health, healthy glucose metabolism and healthy aging.

This collection includes alpha lipoic acid capsules from 100 to 600 mg and the more active R-lipoic acid form, from practitioner brands such as Thorne, Pure Encapsulations, Klaire Labs, Jarrow, Protocol for Life Balance and NutriDyn.

How to Choose an Alpha Lipoic Acid Supplement

• Alpha lipoic acid: The standard form, a 50/50 mix of R and S forms. Thorne Alpha-Lipoic Acid 300 mg is our top seller.
• R-lipoic acid: The natural, more active form, so doses are usually lower (100 to 200 mg). Pure Encapsulations R-Lipoic Acid (stabilized) is a popular pick.
• Dose: Most products provide 100 to 600 mg. Higher amounts are often split into two doses.
• Combinations: Some formulas pair ALA with biotin, B vitamins or other nutrients for nerve and glucose support.

ALA is best absorbed on an empty stomach, about 30 minutes before a meal. Because it supports healthy glucose metabolism, talk with your practitioner first if you take blood sugar or thyroid medication. See also blood sugar support and glutathione.
