Reducing Lactic Acid and Ammonia Buildup. When we train – whether we run, lift heavy weights, or attack a spin class – our bodies produce ammonia and other toxic by-products. A build-up of these by-products leads to a reduction in athletic performance. Step forward, Citrulline Malate. It plays an important role in the Urea Cycle, helping to eliminate these by-products, increasing your ability to maintain performance and fight off muscle fatigue. Greater Nitric Oxide Production. Supplementation of Citrulline Malate is shown to increase Arginine levels in the body, which supports the production of Nitric Oxide. This in turn has benefits like increasing blood flow, oxygen transportation and nutrient uptake, as well as assisting muscle functions for improved output and growth. Supports the ATP System for Prolonged Output. It is believed that supplementing with Citrulline Malate can also assist athletes by increasing aerobic energy production – allowing you to reach higher endurance thresholds. There is also evidence of improved phosphocreatine recovery, post-exercise.
