Our L-Arginine Caps provide 700 mg of L-arginine along with 10 mg of vitamin C to support arterial health and more.

This semi-essential amino acid is involved in numerous areas of human biochemistry that contribute to overall health.

A Key Building Block

L-arginine is an amino acid involved in numerous areas of human biochemistry, including ammonia detoxification, hormone secretion and immune modulation. It is a key building block for maintaining healthy tissue and bones. In addition to building protein, L-arginine serves as a precursor to nitric oxide, which is needed to help the arterial system retain youthful elasticity.
