L-Arginine SR the amino acid L-Arginine in a unique vegetable-based wax matrix that releases L-Arginine gradually. An optimal blood level of L-Arginine is critical for vascular health. Your endothelium – the layer of cells that line your blood vessels - relies on this amino acid for a healthy production of nitric oxide. In turn, nitric oxide plays a key role in vascular health, including promoting blood vessel relaxation and optimal blood flow.

L-Arginine and its ability to support blood vessel health is ideally suited for athletes, active adults and others interested in maintaining healthy blood vessel function. Adults interested in overall health can benefit from L-Arginine SR as well. L-Arginine - one of the body's most metabolically versatile amino acids - also plays a role in immune health, detoxification, protein synthesis, hormone regulation, male fertility, and more.
