It improves training intensity, endurance, and speed of recovery. It performs increases blood Arginine levels, increases endothelial Nitric Oxide(NO) levels thereby improving vascular function and blood flow, improves kidney bicarbonate reabsorption providing a powerful buffer against increasing muscle acidification during intense training, detoxifies fatigued muscle tissue by removing ammonia (a toxin that can increase 3-fold during intense training), rapidly replenishes PCr (phospho-creatine) stores, PCr is a key storage of energy muscles tap into
