Promotes Nitric Oxide Production! Citrulline Malate [2:1] improves training intensity, endurance and speed of recovery. It performs this through 5 main functions:Increases blood Arginine levels (gram for gram at double the level of Arginine).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.ALLMAX’s Citrulline Malate [2:1] is a premium high quality with 2 L-Citrulline amino acids bound to 1 Malate. Aside from assisting with delivery and absorption, the Malate has a critical function in the TCA (or Krebs) cycle that produces energy within the mitochondria. Specific research has shown a 34% increase in the rate of oxidative ATP, 20% increase in post-exercise phosphocreatine recovery and significant reduction in the sensation of fatigue.
