Citrulline is an amino acid that works in the urea cycle, alongside L-arginine and L-Ornithine. L-Citrulline has been used as a sports performance supplement and to support cardiovascular health. It increases the concentrations of other amino acids (Arginine) in the blood increasing NO (Nitric Oxide) production which in turn improves blood flow to muscles during exercise.
