This supplement also combines the benefits of citrulline malate (nitric oxide pump) and electrolytes that help enhance your workout experience without letting fatigue set in. Citrulline Malate converts to Arginine which further forms nitric oxide in the body. Nitric oxide acts as a vasodilator that helps pump blood and nutrients to muscles during exercise.
