Citrulline is a non-essential amino acid, but its usefulness to the athlete is quite remarkable.

This amino acid is a precursor of arginine, but seems much better assimilated than the latter by the intestines.

It significantly increases vasodilation by stimulating the production of nitric oxide.

Citrulline supplementation has been shown to increase performance, reduce fatigue fatigue and may stimulate protein synthesis.

In addition, chronic consumption of Citrulline would lower blood pressure and thus promote better health of the circulatory system.
