What is Melatonin?
The human body is making melatonin on a regular basis. Melatonin is one of the most important hormones produced in our organisms. Melatonin is responsible for controlling our sleep and wake cycle.
Melatonin is produced in the pineal gland in the brain. This pea-sized part of the brain is located right behind our eyes. Because pineal gland is situated right behind our eyes, it receives the information about the amount of light coming through the lenses of our eyes. For that reason the pineal gland is sometimes referred as a “third eye.” If there is light around, there is an interference with the signal that our brain is sending to our cells in order to repair them. Since there is so much interference, the brain would not send these signals, as the cells would not hear the signal anyway. The brain waits until it’s dark to send these signals.
The studies have shown that the brain can’t distinguish between the electrical light and the natural daytime light, which the sun gives.
During the day time, the pineal gland is working hard in making melatonin for storing it for further usage. Under low light levels conditions, the pineal gland starts to release melatonin, this way creating a sleepy feeling, which eventually makes us fall asleep. While we are sleeping, the pineal gland is still releasing melatonin, until there is the time for us to wake up. Then, at the end of the sleep-wake cycle, the pineal gland gets back to produce melatonin once again. So the cycle continues.
How does melatonin work?
Melatonin is the bodies wonder natural drug.
Melatonin is a very powerful antioxidant. For example, melatonin is five times as powerful as Vitamin C and twice as powerful as Vitamin E. Each day our body leaves around half a billion cells. At night, these cells are replaced through the process of dividing the cells. Melatonin is moping out free radicals, which are the leftover product of making the energy, which we need to repair our cells in the first place. As our body repairs itself each night, millions of these free radicals are created. They attack healthy cells, and are the cause of many deceases, including cancer. This is where melatonin comes to help healthy cells in the battle with free radicals. Melatonin is a very powerful hormone and an anticancer agent.
Melatonin also makes your skin look younger.
Frequently Asked Questions on Melatonin
What is melatonin?
Melatonin is a natural hormone that comes from pineal gland. It is responsible for initiating sleep cycles. It is not so much that it puts you to sleep. Melatonin has a major role in helping you go through all stages of sleep, which is very important to heal and restore your body.
What function melatonin has?
Melatonin also calms down a brain’s neuroactivity, relaxes muscles, slows digestion. A good way to think about melatonin, is to compare it cortisol, which is a stress hormone with high levels of it in the daytime. Melatonin is the opposite; it is lower in the daytime. But as you get towards nighttime, cortisol is dropping and melatonin is coming up. These two hormones sort of counterbalance each other.
Most of these effects are traditional effects of melatonin, They happen with melatonin anywhere between .5 and 3 mg at night.
Melatonin can be very powerful for some people. If you have never taken it before, please, do not start with 3 mg a dosage. There is a famous saying used in medicine, “Start low and go slow.” Whether you are dealing with a prescription drug, exercise or melatonin supplements, start slowly, with a lower dosage, and see what happens.
What are the benefits of melatonin for the human body?
Except being a sleep regulator, melatonin has a number of functions, all of which are beneficial to our health and overall well-being.
First, melatonin is good for your bone loss. Animal studies have shown, that melatonin helps preventing bone loss. This is crucial for the older generation, who can experience bone loss, caused by a variety of conditions, such as osteopenia. Older animals’ studies have shown that indeed melatonin helps with bones. The animals were divided into two randomly assigned groups. The first was treated for 10 weeks with melatonin, and the second group was not treated with an anything. What they found is that animals treated with melatonin had a higher bone volume, they had more middle part of a bone, and thicker edges of the bone in comparison to control group.
This is exactly what is happening with the human body as well, as animals make a traditionally very good model for studying effects on the human bodies.
Another effect of melatonin is the increased bone flexibility. Bone strength is not really connected with how much calcium and, mineralization is in the bone, these can actually make the bone weaker. Bone strength is measured by flexibility. Especially long bones, for example, bone in your arms and in your legs. That flexibility does not come from minerals, it comes from the special protein. Melatonin has an effect on bone flexibility and therefore, bone strength. These compelling results were indicative of that dietary supplementary melatonin is able to exert beneficial improving of microstructure and biochemical improvement of aged bones.
What if someone has a reduced amount of melatonin?
If you have a reduced amount of melatonin, your immune system starts to be less competent. You also will probably have a sleep disturbance. You can’t get off the sleep easily. And if you do, you can’ get back to sleep easily. Also, because melatonin protects your heart as well, if the levels of melatonin are insufficient, you can also have certain heart complications.
Since your immune system is not functioning to make its best, you are much more prone to a variety of deceases.
Just to provide you a very striking example, the average woman with breast cancer, has only one tenth of the normal level of melatonin.
Another example: people with prostate cancer have less than half of the level of melatonin than they should have had.
Also, children with autism also have reduced levels of melatonin. It is on average half as much as they should have in their age.
If an individual is working nights, his or her level melatonin are also get reduced with time, which makes him or her more prone to have cancer.
People who are blind have also different cancer rate than the average population.
How long melatonin lasts?
Time release of melatonin is around 3 to 4 hours. If you are planning to move your sleep schedule for more than three hours, you may want to take another pill in three hours.
Can melatonin prevent headaches?
As a matter of fact, it can. Recent studies have shown that melatonin is good for migraine sufferers. Taking melatonin supplements 30 minutes before bedtime can help curb migraine headaches. This is according to the small study conducted by Brazilian scientists. During the first months of the studies, the participants did not take any melatonin, while the observants were looking into the migraine pattern in the participants. During the studies last three months, the participants took 3mg of melatonin 30 minutes before the bedtime. They found at these studies that two thirds of participants said that the migraines were reduced, by half or even better. Some said that the migraines were gone at all. Overall headache intensity was also reduced at the beginning of the study. The women’s average migraine level was 7 in the scale 0 to 10. And that dropped to 3 on the same scale by the end of the study.
3mg of melatonin 30 minutes before your bedtime might be something you want to discuss with your physician if you suffer from migraines.
What is liquid melatonin?
Melatonin in a liquid form is a very effective pill that works a bit faster than a regular melatonin pill.
The inner capsule is with melatonin timed-release beadlets. It is in a liquid melatonin−filled outer capsule. It releases a hormone immediately, which gives a quick sleep response. On the other hand, the inner capsule, where melatonin packed in different sizes, dissolves at intervals to promote a balanced sleep.
What is the optimal dosage of melatonin supplements?
It is generally better to start with half of milligram, and then gradually increase the dosage up to 3 mg. However, the dosages should be adjusted according to your individual response.

It is not a reaction however; this is just a normal response for people. These effects mean that the dosage was too high for you. Just lower the dosage slightly and you will be ok.
Why it is necessary to take melatonin?
Melatonin production levels can be different from person to person. There are many factors that can affect the production of melatonin. These include age, lifestyle, exposure to light, working conditions, overall environment, oxygen levels outside, diet, and many more. If you find yourself suffering from occasional sleeplessness, that is a good sign that your body is not producing the amount of melatonin it actually needs. Taking supplemental melatonin can help filling this gap.
What studies on melatonin show?
There have been more studies on melatonin than even on paracetamol.
Over the years, scientists have conducted numerous studies on melatonin and its impact on the human organism. The majority of these studies demonstrate the effectiveness of melatonin while combatting the occasional sleeplessness.
One of these studies was conducted in the University of Glasgow in 2007. The study was examining the effect of melatonin on 523 adults. The study was what is known in science as “double-blind.” One group of patients took placebo, and another group of patients took melatonin. As a result of these studies, the scientists found out that taking melatonin results in significant and clinically meaningful improvements in sleep quality. Melatonin improved morning alertness, sleep onset latency, and what is more important, the overall quality of life.
How much melatonin is too much? Can I have an od of melatonin?
There is no definitive dose of melatonin that would be considered an overdose. Melatonin affects people differently. Some take just little and experience some side effects; others can take hundreds of milligrams and have no adverse effects whatsoever.
Melatonin doesn’t have a suggested dosage like some other drugs have.
It is really an individual drug to take. We recommend you to start with lower dosages and see how it goes. Then you can gradually increase your dosage, if necessary. If your bottle of melatonin has directions of taking 3mg to 5 mg, we recommend you to start with 3mg.

If your kid is experiencing unusual sleepiness, may be right after his or her school or kindergarten is over, or if your kid is having irregular bedtime pattern, you may want to consider using melatonin. It is a natural, safe, and effective medication.
Melatonin is used in children with chronic insomnia. Melatonin also can help the management of sleep if disturbances are present caused by attention deficit/hyperactivity disorder or neurologic injuries.
What is melatonin?
Melatonin is a hormone that is naturally produced in the human brain on a constant basis. The primal function of melatonin is to regulate a sleep cycle. Melatonin’s production going on during the sleep state, while during the doing time its production is suspended. The pineal gland, where melatonin is produced, starts to release melatonin when there is darkness around. That is why it is preferable to follow the sun in your sleep cycle.

- Psychotic episodes
- Autoimmune hepatitis
However, in those cases melatonin was used, but was not identified as a direct cause of side effects.
In cases of children with seizures, melatonin is to be used with extreme caution. Some studies have shown that melatonin may cause worsening of seizures.
Melatonin plays a role in human immune function. For this reason melatonin is not recommended for children with autoimmune disorders.
Is the use of melatonin in children safe?
Parents should become aware, that the studies on melatonin and its side effects are not conclusive to the date.

- If the episodes of insomnia are occasional. For example, insomnia in children is frequent when there is anxiety connected to a new year in school or kinder garden.
- If the insomnia is present, but is relatively short-term. For example, the insomnia may be caused by infections.
- If the insomnia happens because of the result of a physical cause. For example, it may be caused by sleep apnea.
- Avoid using melatonin if your children are of the age under 3 years.
While melatonin is an excellent natural sleep aid, it can never be a substitute for overall healthy sleep practices, such as regular bedtime routines that fit for the particular age, avoiding taking caffeine-contained drinks and food, and avoiding the excessive use of light-emitting devices, like smartphones and laptops.
