Sources

Common foods like wine; olive oil and even beer are abundant sources of the hormone. Also, melatonin is found in lots of common fruits and vegetables like tart cherries, walnuts, grape skins and tomatoes. While a lot of these foods have considerable smaller amounts of melatonin compared to the dose commonly found in a supplement, adding these foods into the diet will be simple and can provide beneficial amounts of the compound.

Amounts

An essential thing to consider is whether the body can obtain adequate amounts of melatonin from food alone. The latest comprehensive review in the Journal of Pineal Research states studies which show considerable increase in both levels of melatonin and the antioxidant status in the blood of individuals who consumed foods rich in melatonin.

Health Benefits

Melatonin acts as an antioxidant by searching directly for the harmful agents which promote inflammation and aging. These agents will result to conditions such as cancer, neurological and cardiovascular problems. Even if more research is necessary, there is actually an agreement regarding the potency of the compound in this matter. Regardless of the detailed, curative effect, melatonin taken through food will provide healthy levels of antioxidants.

Warnings

Typically, melatonin derived from a food source is used due to its health benefits and not as a sleep aid. Primarily, this is because of the time, quantity and spread at which melatonin is taken through food. An over-the-counter supplement can be a better choice if melatonin is used basically for regulating sleep patterns or in alleviating jet lag symptoms. Make sure to consult a doctor before you use supplements as they might interact with other medications.

Considerations

Apart from evaluating the amount of melatonin directly from the source of food, try to consider how to alter the food which could affect the absorption and availability of melatonin. For instance, cooking food at high temperatures or fermentation may affect the amount of melatonin which can be taken from the food. If possible, the food consumed must be fresh and unprocessed in order to get the maximum nutrient value.

According to Iowa State University, oats are among the best food sources of melatonin.  Basically, no foods contain high amounts of melatonin; even the foods which are believed to contain a lot of melatonin such as oats only have small amounts. That is the reason why you need to consume approximately twenty bowls of oats in order to obtain one to three milligrams of melatonin. This is the same amount which can be found in a typical melatonin supplement pill. In order to help your brain produce more melatonin, it is best to eat oatmeal and raisin cookies as a snack and then wash them down with a glass of milk at least an hour before going to bed at night.  Oats have some amounts of melatonin while milk contains an amino acid known as tryptophan.

Rice

Another best source of melatonin is rice as stated by Iowa State University. Rice does not only have melatonin with it, but also has tryptophan. That is why eating dinner which consists of rice like the stir fry meal or casserole baked with rice will be capable of helping your body increase its melatonin levels as your prepare yourself to sleep at night. However, AskDrSears.com warns that intake of a large meal extremely close to bedtime could hinder with sleep. Thus, it is best to opt for a light dinner and eat it a few hours before your bedtime.

Milk and Dairy Products

According to AskDrSears.com, milk and other dairy products derived from milk like ice cream, cheese and yogurt have high amounts of tryptophan. These products are also abundant in calcium. Your body makes use of tryptophan to generate more melatonin and calcium which will be helpful in the process that occurs inside the brain. Due to that, you will be able to promote a good night’s sleep by consuming a glass of milk at night or eat a bedtime snack which consists of several kinds of dairy products.

According to the Mayo Clinic, the most common melatonin side effects are headache, irritability, fatigue, sleepiness and dizziness.

Gastrointestinal

Melatonin can induce gastrointestinal side effects such as vomiting, abdominal cramps and nausea. It is also believed to trigger the symptoms of Crohn’s disease which consist of abdominal pain, cramping and diarrhea.

Seizures

Melatonin can likely increase the risk of seizures particularly in children who are suffering from severe neurologic disorders. Several researchers argue on this matter and would even suggest that this will actually reduce seizures that is why more studies have to be conducted in order to obtain solid evidence. In any way, any individual suffering from a seizure disorder must be closely monitored by their doctor while using melatonin.

Changes in Mood

Melatonin could bring about mood changes most especially in patients who are suffering from depression or psychotic disorders. Some patients may experience feelings of lightheadedness while there are others who will become extremely sad. Any person diagnosed with depression or psychosis has to be closely monitored while using melatonin.

Since melatonin can reduce a person’s glucose tolerance and sensitivity to insulin, patients suffering from type I diabetes have to be cautious when taking melatonin. Patients with diabetes have to be monitored carefully while using the supplement so that their medications will be adjusted if needed.

Hormones

According to a research done at Colorado State University, melatonin is capable of increasing or decreasing other hormones present in the body. These include vasopressin, progesterone, oxytocin, cortisol, luteinizing hormone, thyroid hormone such as T4 and T3, progesterone and estradiol. The hormonal changes can lead to increase breast size in men which is known to be gynecomastia, reduced sperm count or reduced sperm motility.

Definition

The hormone melatonin will regulate the circadian rhythm cycle or the sleep-wake cycle of the body. Both artificial and natural light coming from the environment will determine the amount of melatonin that is released. When it becomes dark, an increase in melatonin will help you fall asleep. As daylight appears, the levels of melatonin can drop to keep you awake. But exposure to bright light at nighttime will disrupt the normal cycle. In addition, melatonin is an antioxidant and is able to control the release of other hormones.

Food sources

Melatonin can be found in a lot of plant sources. But these are only in small quantities which are measured in nanograms that represent one billionth of a gram. Two of the highest food sources of melatonin which are listed at the Dietary Fiber Foods website include the white and black mustard seeds which are smashed into a condiment. A teaspoon of white mustard seed has 378 ng while one teaspoon of black mustard seed also has 258 ng. Moreover, flax seed contains 12 ng/g, sunflower seeds contain 29 ng/g, tart cherries have 15 ng/g and almonds contain 39 ng/g. Oats can also be a good choice but these only contain 1.8 ng/g. Other foods which are included on the list are bananas, poppy seed, tomatoes, rice and red radishes. All of these provide 0.5 ng to 1 ng for every gram of food taken in.

Tryptophan

The amino acid called tryptophan is converted into serotonin and at nighttime, serotonin is converted into melatonin by the pineal gland. Foods which have high amounts of tryptophan can be helpful in increasing the levels of melatonin. Foods with the highest levels of tryptophan include eggs, poultry, peanuts, soybeans, meats, seafood, milk and dairy products.  According to the website Ask Dr. Sears, eating carbohydrates along with tryptophan can increase the effect on the production of melatonin.

Vitamin B5

According to the Linus Pauling Institute, vitamin B5 or pantothenic is a component of the coenzyme which is important for the synthesis of melatonin. Several of the best food sources of vitamin B5 are similar to foods rich in tryptophan like eggs, milk, yogurt and fish particularly cod and tuna. Other food sources are mushroom, lentils, broccoli and sweet potatoes.
