L-citrulline Overview
L-citrulline is an amino acid found in certain foods and synthesized within the body. It plays a vital role in the urea cycle, aiding in the removal of ammonia, a waste product of metabolism. This amino acid is known to enhance nitric oxide production, which can improve blood flow and cardiovascular health. L-citrulline is often used as a dietary supplement to support exercise performance, reduce muscle fatigue, and promote overall cardiovascular function.
