Life Extension Super R-Lipoic Acid 240mg Capsules are a dietary supplement designed to support cellular energy, mitochondrial health and antioxidant protection. Each vegetarian capsule provides 240mg of R-lipoic acid, the biologically active form of alpha lipoic acid used by the body. R-lipoic acid helps protect cells from oxidative stress and supports healthy mitochondrial function, which is important for cellular energy production. Unlike standard alpha lipoic acid formulas that may contain both R and S forms, this supplement provides only the active R form for targeted support. The gluten-free and non-GMO formula is suitable for adults looking to support daily antioxidant defence and cellular wellness.
