WHAT IT IS / WHAT IT DOES

L-Arginine is a conditionally essential amino acid involved in several important physiological processes.

Although the body normally produces L-Arginine, requirements may increase during certain periods of physiological stress.

Nitric Oxide Production

L-Arginine is used by the enzyme nitric oxide synthase to produce nitric oxide.

Nitric oxide is a signalling molecule that helps regulate blood vessel relaxation and vascular function.

Cardiovascular Function

Healthy nitric oxide signalling contributes to normal blood flow and blood vessel function.

L-Arginine supplementation has been investigated for cardiovascular applications, although clinical results vary and benefits are not established for every individual.

Muscle & Connective Tissue Support

L-Arginine contributes to protein synthesis.

Proteins are essential for muscle structure, connective tissue maintenance, enzymes and normal cellular function.

Exercise Performance

Because nitric oxide is involved in regulating blood flow, L-Arginine is frequently included in sports nutrition supplements.

However, clinical studies have not consistently demonstrated improvements in athletic performance from L-Arginine supplementation.
