Citrulline is one of the three dietary amino acids in the urea cycle (the other two are L-arginine and L-ornithine) . Taking citrulline increases plasma levels of ornithine and arginine and improves the ammonia recycling process and nitric oxide metabolism. Consequently, citrulline may be useful in situations in which nitric oxide is relevant, such as athletic performance and vascular health. There are very few foods that have useful amounts of citrulline, but watermelon is a notable exception.
A fair amount of research suggests that prolonged use of citrulline mildly reduces blood pressure and mildly improves blood flow, particularly in individuals with hypertension or other cardiovascular problems. There are also some research which suggests that supplementation with citrulline, both short-term and long-term, can reduce fatigue, increase power output, and improve endurance in both aerobic and anaerobic exercise.
To supplement L-citrulline to enhance sports performance, take 8g of citrulline malate about an hour before exercise. On days that you don't exercise, it can be broken up into smaller doses.
