Arginine is one of the 20 amino acids in the body. As a supplement, research suggests that l-arginine benefits natural processes in the body. Two of its most important functions are to help build and repair muscle tissues and to release nitric oxide into the bloodstream for vasodilation. L-arginine is available in some of our foods, but when that’s not enough to satisfy the body’s needs, we can get it in supplemental forms.
