Overview

NOW Foods L-Citrulline provides 1200mg of pure L-citrulline per tablet — an amino acid that converts to L-arginine in the kidneys, which then produces nitric oxide (NO) for vasodilation and blood flow. L-citrulline is actually more effective at raising arginine levels than supplementing arginine directly, because citrulline bypasses first-pass liver metabolism. Clinical benefits include improved blood flow, reduced blood pressure, enhanced exercise performance, and better erectile function. The 1200mg per tablet allows flexible dosing (2-4 tablets for clinical doses).
