L-Citrulline is an amino acid that plays an important role in nitric oxide metabolism and regulation.L-Citrulline is converted to L-Arginine to support L-Arginine and nitric oxide levels. Increased production of nitric oxide promotes vascular dilation which improves oxygen and blood circulation throughout the body. Supplementing L-Citrulline is the most effective way to boost nitric oxide levels over a longer period of time. This means L-Citrulline supplementation will be recycled to L-Arginine and then to Nitric Oxide in body. So why not simply Supplement L-Arginine instead? The reason is simple: Citrulline is proven to be more effective at increasing plasma arginine levels than supplemental arginine.
