Arginine is an amino acid that has many functions in the body. It is metabolized to nitric oxide, which is a necessary factor in the normal dilation of blood vessels, to help supporting normal blood flow and heart health. L-Arginine also maintains epithelial integrity of the gastrointestinal tract and skin, while enhancing collagen synthesis. L-Arginine is one of the two main amino acids which promote sperm motility.
