NOW Sports Sustained Release L-Citrulline Amino SR™
NOW® L-Citrulline is a supplemental source of this non-essential but extremely important amino acid. Citrulline plays a unique role in the support of protein synthesis and positive nitrogen balance, particularly in muscle tissue, making it ideal for athletes and active individuals. NOW® L-Citrulline Sustained Release (Amino SR™) Tablets allow for prolonged citrulline release, which in turn supports sustained protein metabolism.
