L-Citrulline

Citrulline is a non-essential amino acid, but its usefulness in athletes is quite remarkable.

This amino acid is a precursor to arginine, but appears to be much better absorbed by the intestines than the latter.

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

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

Furthermore, chronic consumption of Citrulline may lower blood pressure and thus promote better circulatory system health.
