XPN - L-Citrulline

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 the feeling of fatigue during exercise and may stimulate protein synthesis.

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