L-arginine is an amino acid that helps the body to form proteins. In general, the body usually makes all the L-arginine it needs without external assistance. L-arginine is contained in most protein-rich food, like fish, red meat, poultry, soybeans, whole grains, beans, and dairy products.As a supplement, L-arginine can be ingested orally, applied externally, or injected intravenously. Given that L-arginine serves as a vasodilator to widen blood vessels, a lot of people take oral L-arginine for treating heart diseases and erectile dysfunction.
