Citrulline is found in cucumbers and melons, such as watermelon and cantaloupe; however, research is limited in demonstrating the types of foods containing citrulline that will increase nitric oxide production. Watermelon, including the flesh and rind, is a rich source of citrulline.
This results in vasodilation, or widening of the blood vessels, and an increase in blood flow. Nitric oxide helps the blood vessels maintain their flexibility so that the blood can flow unrestricted throughout the body, including the penis. As mentioned, L-arginine is the substance the body uses to create nitric oxide.
