L-Arginine

About L-Arginine

L-arginine is classified as a conditionally essential amino acid. It is essential for infants due to their inability to synthesize L-arginine. L-arginine becomes conditional in adulthood.

Uses/Benefits

L-arginine is the only naturally-occurring amino acid that produces nitric oxide. Nitric oxide is essential to the body for circulatory health. It helps with the elasticity of arterial walls and increases vasodilation, allowing for better blood flow. L-arginine is widely used by athletes to recover from fatigue. In addition, L-arginine participates in numerous other functions, including ammonia removal, cell division and wound healing. Please go to Ajinomoto Research to review clinical work on L-arginine.
