L-arginine is a semi-essential amino acid involved in numerous areas of human biochemistry, including ammonia detoxification, hormone secretion and immune modulation. Arginine is also well known as a precursor to nitric oxide (NO), a key component of endothelial-derived relaxing factor, an endogenous messenger molecule involved in a variety of endothelium-dependent physiological effects in the cardiovascular system.
L-ornithine is a metabolite of arginine in the body, formed as a by-product of the action of the arginase enzyme on arginine. L-arginine is required for the body to synthesise nitric oxide, which enables the arterial system to retain its youthful elasticity. Nitric oxide also helps to produce an endothelial-derived relaxing factor, which is needed by the arterial system to expand and contract with each heartbeat.
L-arginine may also help maintain the health of the immune system.
L-arginine is a key building block to maintaining healthy tissue and bone. L-ornithine may also be used for this purpose.
