About this product
Sustained ReleaseDietary SupplementCirculationHeart/VesselsMen's HealthThrone ExclusiveGluten FreeNSF Contents CertifiedL-arginine is a conditionally essential amino acid, meaning that while your body can make it, it becomes necessary to get it in through diet or supplementation under certain circumstances or for certain physical conditions. L-arginine, like other amino acids, is a building block of protein, which helps to promote muscle and tissue repair, helps to support a healthy immune system, and benefits cellular metabolism.One of L-arginine’s unique functions is that it is necessary for the production of nitric oxide. Nitric oxide is essential to the regulation of blood flow in the body. By supporting nitric oxide levels, L-arginine can support cardiovascular health, benefit healthy blood pressure, and optimize blood flow to the extremities.
