Researched for: L-Citrulline evidence and protocol review
Also known as: Citrulline
L-citrulline is converted to L-arginine in the kidneys, and subsequently to nitric oxide - a potent vasodilator supporting blood flow and oxygen/nutrient delivery to tissue. Because dietary arginine undergoes significant first-pass hepatic metabolism, citrulline supplementation is often more effective at raising plasma arginine levels, per the PubMed Central narrative review on arginine/citrulline supplementation.
