All watermelon contains citrulline.
Citrulline has antioxidant properties and converts to arginine.
Arginine is an essential amino acid that is beneficial to the heart, immune system and circulatory system.
But most of that citrulline is found in the rind.
Eating a rind might sound unappetizing, but it can be pickled (like a cucumber), or simply sautéed and seasoned.
Or throw it in a blender with the watermelon flesh, and add some lime.
In addition to citrulline, watermelon is also a great source of potassium, vitamin A and vitamin C.
