L-Citrulline - Nitric Oxide & Endurance Support for Blood Flow, Stamina & Recovery
About L-Citrulline
Promote healthy circulation, endurance, and vascular performance with our L-Citrulline Supplements collection at Coal Harbour Pharmacy. L-Citrulline is a non-essential amino acid that increases nitric oxide (NO) production, helping blood vessels relax and improving oxygen and nutrient delivery throughout the body. Widely used in pre-workout and cardiovascular formulas, it also supports muscle recovery, reduces fatigue, and contributes to erectile and circulatory health.
What Is L-Citrulline?
L-Citrulline is naturally found in watermelon and converts in the body to L-Arginine, which then increases nitric oxide levels. Unlike direct arginine supplementation, citrulline is better absorbed and sustains nitric oxide production longer — making it a preferred option for endurance, pumps, and vascular support.
