CAS Number: 372-75-8
DESCRIPTION
What It Does: Provides arginine precursor activity for nitric oxide synthesis supporting skin microcirculation.
Why It's Used: Microcirculation-enhancing amino acid that provides arginine for no synthesis with potentially greater bioavailability than direct arginine supplementation.
How It Works: Citrulline is converted to arginine by argininosuccinate synthase, bypassing intestinal and hepatic arginine metabolism for more efficient systemic and local delivery to skin.
Typically Found In: Anti-fatigue formulations,microcirculation products

SCIENTIFIC NOTE
Citrulline bypasses the intestinal absorption limitations of arginine and the hepatic first-pass metabolism that degrades orally-consumed arginine before it reaches peripheral tissues. this makes citrulline a more efficient arginine precursor for peripheral no synthesis, including in skin.
