- Understanding L-Citrulline: A Powerful Functional Ingredient
L-Citrulline is a non-essential amino acid that plays a crucial role in the urea cycle, detoxifying ammonia and supporting healthy metabolic activity. Its real value, however, lies in its ability to increase nitric oxide (NO) synthesis by converting into L-arginine in the kidneys. Higher NO levels lead to improved blood flow, better oxygen delivery, enhanced stamina, and improved muscle pump—making it a favorite supplement among athletes and fitness enthusiasts.
