L-arginine is an amino acid that helps the body build protein. Your body usually makes all the L-arginine it needs. L-arginine is also found in most protein-rich foods, including fish, red meat, poultry, soy, whole grains, beans and dairy products. As a supplement, L-arginine can be used orally and topically.
L-Arginine is a conditionally essential amino acid that acts as a nitric oxide precursor. Nitric oxide is known to increase blood flow which helps promote increased vasodilation and nutrient delivery. USN L-Arginine contains 1000mg from the premium HCL source for fast absorption.*
