Now Alpha Lipoic Acid


Metabolic antioxidants and potent free-radical quenchers that function to improve states of oxidative stress. Alpha lipoic acid is a metabolic antioxidant. Its metabolic functions provide energy to cells and power to the body. Its antioxidant functions protect the body from the damaging free radicals that lead to aging and numerous disease states. This is NOW’s highest potency alpha lipoic acid supplement.


Alpha lipoic acid (ALA) is made naturally in the body and may protect against cell damage in a variety of conditions. Food sources rich in alpha lipoic acid include spinach, broccoli, and yeast. ALA exists as two different enantiomers; the biologically active (R)-isomer and the (S)-isomer, found primarily in synthesized ALA supplements. NOW ALA is a mixture of these two isomers. Alpha lipoic acid and the metabolite, dihydrolipoic acid (DHLA), have antioxidant activity and can scavenge free radicals both intra- and extra-cellularly. Alpha lipoic acid is both water and fat soluble and can regenerate endogenous antioxidants, such as vitamin E, vitamin C, and glutathione to prevent oxidative damage. This is why it is often referred to as the "universal antioxidant". This formulation also includes grape seed and black pepper extracts to provide synergism and additional antioxidant protection. Product is suitable for vegetarians and vegans.

Adult Dosage: Take 1 capsule daily with meals.
