L-Citrulline is a compound consisting of Citrulline, a nonessential amino acid that is primarily found in watermelon, and Malate, an apple derivative.

Research has shown that supplementation of Citrulline raises Arginine levels more effectively than taking the same dose of straight Arginine.

L-Citrulline is a non-essential amino acid that supports the optimization of blood flow to the tissues. L-Citrulline functions in the body by being converted to L-Arginine and then into nitric oxide (NO). This nitric oxide is then going to be involved with vasodilation. This vasodilation is what helps increase the amount of blood and oxygen that is delivered to the working muscles, helping to prevent both mental and physical fatigue.

Malate serves as an important component in the tricarboxylic (or TCA) cycle, which is one way your body produces energy. When you increase malate levels, you increase energy production. Therefore, L-Citrulline Malate provides the one-two punch of bringing additional blood—and subsequently, oxygen and nutrients—to exercising muscles, as well as providing increased energy to boost performance levels.

Studies show subjects using L-Citrulline Malate have an increase in the rate of muscle ATP (Adenosine Triphosphate, the major energy source within the cell) production during exercise and greater phosphocreatine recovery after exercise.
