Now Foods L-Citrulline Powder - 4 oz

Citrulline is a non-essential amino acid that is an important intermediate in the urea cycle, functioning along with Arginine and Otnithine 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, therby 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.
