Natroceutics Alpha Lipoic Acid Bioactive: ALA supports mitochondrial energy metabolism, cellular detoxification, and overall physiological resilience. All known biological systems that utilize alpha lipoic acid (ALA) rely exclusively on the r-form, the natural enantiomer synthesized in the mitochondria and incorporated into enzyme complexes that convert food into cellular energy and support antioxidant defenses. This form plays a role as both an electron-transfer agent and redox-active coenzyme.
