What is L-Citrulline?
L-Citrulline is a non-essential amino acid, meaning it’s not necessarily required through your diet, but increased L-Citrulline intake has numerous health benefits. It can be found in numerous food sources, but supplemental intake helps ensure adequate intake for your goals.
L-Citrulline is mostly used in sports supplements as a means to increase arginine levels in the blood which promotes increased nitric oxide (NO) levels and oxygen/nutrient delivery through vasodilation (opening of blood vessels). This generally causes notable increases in endurance, performance, muscle pumps, and muscular growth. Ironically, consumption of citrulline is more effective at increasing arginine levels than using straight L-Arginine because of the superior absorption characteristics.
Who should use it?
Citrulline, particularly L-Citrulline Malate, is most often used by athletes as part of pre-workout regimens and it’s often the main and most potent ingredient in pre-workout supplement formulas. As mentioned above, it’s fantastic for creating intense muscle pumps and improved performance due to increased nitric oxide levels and improved vasodilation.
Because it’s such a potent vasodilator, L-Citrulline is also good for your heart, blood vessels, and overall cardiovascular health. It’s also beneficial for improving protein synthesis via signaling pathways, so it can improve your performance (and feel) while exercising or competing in sports, and it can also help lead to improved muscle gains.
Plus, because of its positive effect on opening blood vessels, L-Citrulline is often used as a natural aid for mild to moderate erectile dysfunction for those individuals wishing to avoid common pharmaceutical assistance.
When and how should it be used?
L-Citrulline Malate is the most potent form of citrulline, and it’s best used in synergy with other performance-boosting ingredients in pre-workout and intra-workout formulas. Because of the vasodilation effects, those same formulas can also be used for effective fat burning when used prior to aerobic or cardiovascular exercise (not just weight training or strength training).
