A list of foods high in melatonin.

You can naturally boost your daily melatonin intake, eating common foods rich in melatonin, such as cranberries, pistachios, almonds, apples, cherries, strawberries, and drinking Merlot wine.

What is melatonin?

Melatonin is a hormone that the human body naturally produces. We can also get melatonin from food or dietary supplements.

Above all, melatonin regulates sleep. It’s the internal clock of the human body. Actually, melatonin levels rise before bedtime and remain high during the night. Eating foods high in melatonin before bed or at dinner may help you sleep better at night.

Also, melatonin is a powerful antioxidant and has many health benefits. Melatonin has antioxidant, anti-inflammatory, anti-diabetic, and anticancer activity. In addition, it boosts the immune system, protects the cardiovascular system, and promotes weight loss.[1]

How much melatonin does the human body naturally produce?

Each person can produce different amounts of melatonin a day. It depends on many factors:

  • melatonin production decreases with aging.
  • being overweight may be bad for melatonin production.
  • light exposure at night inhibits melatonin synthesis. Especially exposure to blue light.

The human body can naturally produce about 10–80 mcg of melatonin per night. On the other hand, it doesn’t produce any significant amounts of melatonin at the daytime.[2]

Furthermore, the human body doesn’t store melatonin. It is instantly released into the blood. Excess melatonin is excreted through urine. Therefore, getting high doses from supplements is safe for healthy people.

Do pistachios have melatonin?

Many nuts and seeds are good dietary sources of melatonin.

To begin with, pistachios are among the richest foods in melatonin, containing 23.3 mcg of melatonin per 100g, or 6.5 mcg per 1oz.

Actually, pistachios are the best snack before bed for a good night’s sleep. A handful of pistachios before bedtime may help people with insomnia or jet lag.

Don’t eat too many pistachios, though. They’re high in calories. Too many pistachios can make you gain weight.

Are walnuts & almonds good dietary sources of melatonin?

Nuts are plant-based foods with the highest melatonin content. Besides pistachios, walnuts and almonds are also good sources of melatonin. Almonds have 3.9 mcg, while walnuts have 0.35 mcg of melatonin per 100g.

Therefore, nuts, such as almonds and walnuts, are a great night snacks. They could help you sleep at night or improve sleep quality.

Which fruits have the highest melatonin content?

Most fruits are poor in melatonin. Only cranberries, grapes, strawberries, cherries, apples, and bananas have decent amounts of melatonin.

Cranberries are the richest common food in melatonin

Cranberries are particularly high in melatonin. They contain between 250-960 mcg of melatonin per 100g! Actually, cranberry is the richest fruit in melatonin! So, eating cranberries or drinking cranberry juice before bed might improve sleep quality and duration.[3]

Banana is a melatonin-rich fruit

Banana is another common melatonin-rich fruits. It contains 0.07 mcg of melatonin per 100g. A whole banana has about 0.09 mcg of melatonin.

Most noteworthy, banana consumption can increase the concentration of melatonin in the body. According to a study, eating banana increased the melatonin concentration in the body about 330%. Drinking orange or pineapple juice had the same effect. Pineapple juice increased the melatonin concentration about 200%. Orange juice increased the melatonin concentration about 280%.[4]

How much melatonin is in cherries, strawberries & grapes?

Besides bananas, there are many other favorite fruits naturally rich in melatonin:

  • Cherries are among the richest fruits in melatonin. They contain about 1.34 mcg of melatonin per 100g.
  • Strawberries are also plant-based foods high in melatonin. They contain about 1.12 mcg of melatonin per 100g.
  • Grapes are among the highest melatonin containing fruits as well. The melatonin content of each grape variety varies greatly. Most grape varieties have about 0.1 mcg of melatonin per 100g. But, there are certain grape varieties that contain more than 15 mcg per 100g.
  • Grape juice is also rich in melatonin. It contains about 0.05 mcg of melatonin per 100 mL.
  • Orange juice has about 0.3-2.2 mcg of melatonin per 100 mL. The melatonin content depends on the orange variety.
  • Pineapples are great dietary sources of melatonin as well. Pineapples have about 0.03 mcg of melatonin per 100g.

Apples are good dietary sources of melatonin

Apple is another common fruit rich in melatonin. Depending on the variety, apple has between 0.7 and 6.7 mcg of melatonin per 100g.[5]

The peel of an apple is much higher in melatonin than the flesh. For instance, the “Granny Smith” variety has 10 times more melatonin in the peel than the flesh or the juice!

So, eating these melatonin-rich fruits in the evening may help you sleep better at night.

How much melatonin is in cereals?

Most cereals are great dietary sources of melatonin:

  • corn is particularly rich in melatonin. The mean melatonin content of corn is 9.6 mcg per 100g. The melatonin concentrations of corn depend on the variety, though. There are corn varieties that contain more than 200 mcg of melatonin per 100g!
  • rice is another cereal high in melatonin. The mean melatonin content of rice is 1.6 mcg per 100g. There are rice varieties with 26.4 mcg of melatonin per 100g!
  • wheat is also naturally high in melatonin, with 12.5 mcg of melatonin per 100g.
  • barley is also a good source of melatonin, with 8.2 mcg of melatonin per 100g.
  • oats are good sources of melatonin as well. They contain approximately 9.1 mcg of melatonin per 100g.

As a rule of thumb, the crumb of bread is richer in melatonin than the crust.

Therefore, eating corn, rice, wheat, barley, or oatmeal can help you sleep better at night. Moreover, oats, wheat, barley, and rice are also great dietary sources of GABA. GABA is a chemical which also helps us sleep better at night.

  • mushrooms are particularly rich in melatonin as well. Especially, certain mushroom varieties, such as Basidiomycota and Agaricus bisporus. These varieties contain up to 1,290 mcg and 640 mcg of melatonin per 100g, respectively. Melatonin content of mushrooms varies greatly, though. It depends on the mushroom variety, cultivation practices, and light conditions.

In addition, vegetables and other melatonin-containing foods could help the human body naturally produce more melatonin.

Which beans are high in melatonin?

Beans and legumes contain small amounts of melatonin. Only sprouted lentils are high in melatonin. They have about 100 mcg of melatonin per 100g! Actually, lentils are great for dinner. They could help us lose weight and sleep better at night.

Microgreens & sprouts may increase the melatonin content of seeds

Microgreens and sprouts have amazing health benefits and a superior nutritional value as compared to seeds. The germination process increases the melatonin concentrations of seeds.

Certainly, drinking a cup of coffee before bed isn’t a good idea. Caffeine in coffee reduces the body’s ability to naturally produce melatonin.[2] So, better prefer decaffeinated coffee at night.

Do I need melatonin supplements?

Actually, most people will never experience melatonin deficiency.

First, melatonin supplements contain high doses. Much higher doses than the human body can produce or naturally present in food.

Most melatonin supplements contain melatonin doses of 3-5 mg per tablet. This dosage can be 60 times higher than our bodies can naturally synthesize per night. But, melatonin supplementation is the easiest way to boost your daily melatonin intake.

You’ll find a wide variety of melatonin supplements on iHerb.

You better prefer supplements with the minimum dose of 1 mg (1,000 mcg), though. This dose is more than enough for most healthy people.

Always consult your health care provider before taking any dietary supplement.
