Applied Nutrition Citrulline Malate 2:1 is a performance-focused sports nutrition supplement designed to support nitric oxide production, improve blood flow, and enhance overall training performance. Citrulline malate is widely used in pre-workout formulations due to its ability to support increased circulation and nutrient delivery to working muscles. By supporting vasodilation, this formula helps increase oxygen and nutrient transport during exercise, contributing to improved muscle pump, reduced fatigue, and enhanced endurance. It is commonly used by athletes and fitness enthusiasts during both resistance and high-intensity training sessions.
