Melatonin: Some foods actually have small amounts of melatonin in them. And some foods have been found to help raise your body’s production of melatonin. Tart cherries are far and away the food source with the highest amount of melatonin, but there is also a tiny amount found in walnuts, ginger root, and asparagus. Some of the foods that have been found to naturally boost your body’s melatonin levels are pineapples (the leader in one particular study), tomatoes, bananas, and oranges.
