Arginine is a conditionally essential basic amino acid involved primarily in urea metabolism and excretion, as well as in DNA synthesis and protein production. It is an important precursor of nitric oxide (NO) and thus plays a role in the dilation of blood vessels.

More facts
L-Arginine is an amino acid that promotes heart health.* It stimulates nitric oxide, a compound involved in circulatory function.* Nitric oxide degrades very rapidly after its formation. L-Arginine serves as the precursor for continued nitric oxide production.
