NOW Foods Alpha Lipoic Acid 600 mg delivers a potent dose of this uniquely versatile antioxidant — often called the universal antioxidant because it works in both water-soluble and fat-soluble environments, allowing it to neutralize free radicals throughout the body. ALA also has the rare ability to regenerate other antioxidants including vitamins C and E, CoQ10, and glutathione, effectively amplifying the entire antioxidant network. Clinically, ALA is most studied for blood sugar metabolism support (as an insulin sensitizer), nerve health (particularly diabetic neuropathy), and liver protection. Each vegetarian capsule delivers 600 mg of pure alpha lipoic acid — a clinical-level dose — manufactured in NOW's GMP-certified facility and tested for identity, potency, and purity. Free from artificial additives and suitable for vegetarians and vegans.
