L-Citrulline

One of the primary benefits of L-citrulline for athletes is its ability to increase nitric oxide levels in the body. Nitric oxide is a molecule that helps to dilate blood vessels, increasing blood flow and oxygen delivery to muscles. This increased blood flow can improve endurance, reduce muscle soreness and fatigue, and enhance recovery after exercise.

In addition to its effects on nitric oxide and blood flow, L-citrulline has also been shown to improve the body's energy production. During exercise, the body uses ATP (adenosine triphosphate) for energy. L-citrulline can help to increase the rate of ATP production, allowing athletes to sustain high-intensity exercise for longer periods of time.
