NOW Citrulline is a non-essential amino acid that is an important intermediate in the urea cycle, functioning along with Arginine and Ornithine to rid the body of ammonia, a byproduct of protein metabolism.
Because Citrulline is a precursor of Arginine, it provides a readily available source material for Arginine production, thereby helping the body maintain healthy Arginine levels.
Citrulline also plays an important role in the healing process and in the maintenance of a healthy immune system.
