L-Citrulline Pure Powder by Now Foods is the non-essential amino acid citrulline, which intervenes in the urea cycle, acting together with the amino acids arginine and ornithine to release excel ammonia from the organism, a metabolic waste product from physiological processes.
Citrulline is a precursor to arginine, a process that takes place in the kidneys, and which results in the secretion of nitric oxide in our organism. This latter provides particular benefits for the heart and blood vessels, boosting blood flow and lowering blood pressure, as well as ensuring better transportation of nutrients towards the tissues and optimal oxygenation.
Citrulline is even considered to be better than arginine in achieving these effects. L-Citrulline Pure Powder can be deemed to be a tool for improving ongoing athletic performance, of both an aerobic and anaerobic nature.
