Should I Take Melatonin? What’s Melatonin And How To Use It?

We’ve all had sleepless nights, and while twisting and turning in bed, we were wondering how to help ourselves to finally fall asleep.

You might have made a chamomile tea that’s supposed to calm you. But nothing happened. What would be some alternatives?

You heard about supplement pills everyone’s speaking about. You may be asking yourself now: ”Should I take melatonin?”.

Melatonin is a hormone found naturally in the body. But is it the same as the one you take in pills? Is it bad to take melatonin?

First, let’s discover main things about this hormone before jumping to conclusions.

What Is Melatonin And How Does It Work?

Melatonin is a hormone that your body normally produces and plays a big role in your sleep cycle.

Your brain controls the production of melatonin according to daylight.

Accordingly, your body produces and releases higher levels of this hormone during night time, and then decreases its production during the daytime. Melatonin actually switches its peak times with cortisol – a hormone that regulates our metabolism and activates our built-in alarm system.

To understand better how it works check out this graph that shows the levels of melatonin and cortisol produced during the day.

It’s our bodies way of switching from the alert phase to the sleeping phase.

Unlike the one naturally made, melatonin in pills is produced synthetically in laboratories. They are safe if used properly, but also the melatonin supplements are not regulated so some people are overusing its application.

How Is It Used And How long Does It Take For Melatonin To Kick In?

Melatonin pills are usually taken by mouth but can be also placed in the cheek or under the tongue in order to allow this hormone to be directly absorbed into the body.

In some severe cases, like treating cancer or post-treating a heart attack, melatonin may also be injected into the muscles or veins.

The amount of time needed for melatonin to kick in depends on the method of using it. When taken as an oral supplement, it needs about 30 minutes to achieve the highest concentration possible in your bloodstream.

What Not To Take With Melatonin?

You shouldn’t take melatonin with coffee or alcohol as this might interfere with your circadian rhythm and alter your natural melatonin production.

If you’re taking other medication you should talk to your doctor first before considering the usage of this supplement.

For instance, mixing birth control pills, anticoagulant drugs or corticosteroids with melatonin might have bad consequences for your organism.

What Is It Used For?

Melatonin is mostly taken for sleep-related disorders. Some take it for jet lag, others for insomnia, but what are all of its applications?

Let’s run through all the disorders and conditions melatonin might help you with :

We now realize that melatonin’s application is pretty wide and covers different ranges of disorders and conditions.

It is also used for treating anxiety, birth control or even to help blind people establish a good day and night cycle.

If you happen to have stopped smoking, or know someone who has, melatonin can reduce side effects of stopping smoking.

How To Use It? When Should I Take It?

So far we have made it clear that melatonin has a main role in regulating our biological clock, also called circadian rhythm. So you would probably use it in the situations when your regular sleep cycle is altered.

Some people take it if they have trouble falling asleep, or simply when they know that some events might interfere with their sleeping time like jet lag, or working late night shifts.

When taking melatonin timing has to be higly respected, as it directly effects your circadian rhythm.

Here Are Some Tips To When To Take Melatonin Based On What You’re Using It For:

  • If you’re troubling with falling asleep, make sure to take it at night and about 30 minutes before bedtime.
  • For people who are night owls and suffer from delayed sleep phase syndrome, should consider using it several hours before the desired time they want to fall asleep. Taking your dose about 2 hours before sleep is advisable in this case.
  • Less than 1% of people are affected by the condition of advanced sleep phase syndrome in which they feel a strong desire to fall asleep and then wake up a few hours too early. In this case, it’s suggested to take Melatonin upon awakening.

If you happen to be a night owl make sure you have ample light exposure at the opposite time from when you take your melatonin dosage.

It is a safe supplement and you can use it on a nightly basis without fearing of adverse consequences. However, before deciding to take it every night or every day, based on your particular sleeping cycle issue, you should talk to your doctor.

What Dose Of Melatonin Should I Take?

The proper dosage is the key in getting all the benefits Melatonin has. According to a study from the Massachusetts Institute of Technology, a perfect dose is one of 0.3 milligrams.

Research suggests that taking lower doses proved to be more effective than taking the stronger variants of the pill. The relationship between the dose and the effect does not appear to be applicable to melatonin.

Although it is known that a dose between 0.2 to 5 mg is considered to be safe, it is hard to say what is an optimal dose for an adult. So, it’s advisable to consult your doctor before including melatonin into your daily routine.

Is It Addictive?

No. As mentioned above, the “sleepy” hormone is safe for use. Melatonin is not habit-forming, therefore you cannot become addicted to it.

Nevertheless, maintaining a healthy lifestyle and regulating naturally your sleep cycle is always a better choice than getting used to consuming artificial supplements. Make sure you don’t overuse melatonin just of pure laziness.

Can I Overdose On Melatonin?

Yes.  Although the dosage varies from the condition you have, you should be careful not to take too much of it. No matter how safe this supplement is, it’s still a hormone and you might overdose on it.

It’s hard to say what dose is too much, but, for example, 30-mg range melatonin might be very harmful.

Overdose symptoms include abdominal cramps, nausea, vomiting, dizziness or anxiety. A Melatonin overdose can give you the most vivid dreams or nightmares or leave you completely dizzy and groggy during the day.


Go for 5 mg or fewer melatonin pills, rather than 20 mg or higher.

Can I Give Melatonin To My Child?

Melatonin is often used in treating sleep problems in children with disorders like autism, cerebral palsy and other intellectual disabilities. Nevertheless, your doctor might prescript minimal dose based on what your child is having trouble with.

Even though it is considered safe, there is still some caution advised in children and pregnant women because of its potential effects on hormones.
