NutraBio L-Citrulline PowderL-Citrulline is a non-essential amino acid that plays a role in the urea cycle and serves as a precursor to L-Arginine in the body.* Research over the past decade has highlighted its involvement in nitric oxide production, vascular function, protein metabolism, and ammonia elimination.*Key Features May support nitric oxide production via L-Arginine conversion* May support protein homeostasis and muscle protein metabolism* Involved in ammonia elimination — a byproduct of protein metabolism* May support normal vascular function* May support healthy blood pressure already within the normal range* 100% pure L-Citrulline — no fillers, excipients, or additives How It WorksL-Citrulline is converted to L-Arginine in the kidneys, which in turn may support L-Arginine and nitric oxide levels in the body.* Nitric oxide plays a role in vascular dilation, which may support normal blood flow and oxygen delivery.* L-Citrulline also contributes to the formation of urea in the liver, which is involved in the removal of waste produced during protein digestion and metabolism.**These statements have not been evaluated by the Food and Drug Administration.
