Unlike other amino acids, Citrulline does not play a role in protein synthesis. However, Citrulline is the key component in the urea cycle and even plays a crucial role in cardiovascular health. Supplementing Citrulline is key for promoting vasodilation. During this process, the Citrulline present in your body is converted into Arginine which is then converted into nitric oxide. This allows an increase in blood flow to the muscles for increased muscle pumps and recovery. The recommended dosage for Citrulline is between 3-6g daily.
