Helps Increases Nitric Oxide Production: Arginine is an essential precursor of nitric oxide and L-Citrulline can be recycled in the Citulline - NO cycle. This way both contirbute to Nitric Oxide Production.

Helps Maintain Blood Vessel Tone: Arginine and Citrulline both lead to production of nitric oxide and nitric oxide help maintain blood vessel tone and thus plays a role in protein synthesis.

L-arginine is involved in creatine formation and the synthesis of creatine provides energy to your muscles for movements, especially quick movements.
