Arginine is a conditionally essential amino acid, which means that supplementation may be required at times of high demand. Arginine is converted in the body into a chemical called nitric oxide. Nitric oxide is a signaling molecule in the body with many functions. Nitric oxide relaxes the smooth muscle in the walls of blood vessels, which increases blood flow.

How Does Arginine Work?

Increase Nitric Oxide

Many metabolic pathways utilize Arginine in the body, including ones that produce nitric oxide, creatine phosphate, agmatine, polyamines, ornithine, and citrulline. Arginine supply is regulated by two enzyme systems: arginase and nitric oxide synthase. Arginine is synthesized from citrulline. Arginine, when infused intravenously, can result in facial flushing and increased secretion of nitric oxide metabolites in the urine, providing evidence of its link to nitric oxide. Subsequent studies showed that Arginine increases growth hormone and insulin release.
