Lipoic acid is produced by plants and animals and synthesizedin humans. In the body, lipoic acid is bound to certain proteinsand is a component of several essential enzyme complexes inthe mitochondria that are involved in energy production andamino acid metabolism.RLA Pro’s therapeutic properties are attributed to a variety oflipoic acid’s mechanisms of action, including its directfree-radical scavenging capability, potent antioxidant activity,and its ability to increase nitric oxide production. Significantclinical research supports lipoic acid’s therapeutic ecacy inregulating glucose metabolism and mitigating diabeticneuropathy and retinopathy.
