What is L-arginine?
L-arginine is an amino acid produced by all tissues of the body. It’s considered a conditionally essential amino acid, meaning the body can synthesize sufficient amounts on its own under normal conditions. In certain situations, the body’s demand for L-arginine increases, but the body may not produce enough, making supplementation beneficial.
