L-Citrulline
2000mgHow It Works
L-Citrulline is a non-essential amino acid that converts to L-Arginine in the kidneys, directly elevating nitric oxide (NO) synthesis. Unlike supplementing L-Arginine directly, citrulline bypasses first-pass hepatic metabolism, resulting in greater plasma arginine availability.
Why It's Here
Improved nitric oxide production means better vasodilation, increased blood flow to working muscles, reduced exercise fatigue, and enhanced oxygen delivery. Clinical trials at 2000â6000mg doses show measurable performance gains in endurance and strength output.
