L-Arginine Powder

L-Arginine, an amino acid considered conditionally essential, plays a central role in urea metabolism, excretion, and DNA synthesis. It serves as the foundational component for synthesizing nitric oxide (NO), a cell-derived relaxant crucial for managing vascular tone and blood flow. Additionally, L-Arginine aids in the production of creatine, a muscle energy substrate, with 95% of creatine concentrated in skeletal muscles. This powdered form provides the advantage of controlled and precise dosing.
