Basically, the rule of thumb states that you should always start with intaking a little amount of melatonin and then increase it according to your needs. But when it comes to how much melatonin can an adult take, the answer is 0.3 mg to 12 mg. But melatonin dosage for adults 10mg is the best amount you should consume to enjoy a good sleep. If you are having no medical issue but trouble in getting a sleep, then exceeding 12mg of this medicine may harm you in any way.

For a better prescription, use an online melatonin dosage calculator and then see your doctor and he/she will tell you how much melatonin for adults is prescribed according to age and weight.

How Much Melatonin Should A Woman Rake During Pregnancy?

During pregnancy, an optimal melatonin dose for a woman carrying a baby is about 1-3 mg. Exceeding this limit may harm the babys health and disturb the mother too. That is why it is a preferable choice to consult a gynaecologist to avoid any inconvenience in future or even during delivery time.

How To Find The Right Amount Of Melatonin For You

If you aren’t sure how much melatonin to take, it is recommended to start with a smaller amount like the 1 mg or 3 mg rather than starting with the maximum. Although melatonin is safe in servings up to 10 mg per day, more is not necessarily better.

Starting with a smaller amount will allow you to see how your body reacts and gauge if your body needs more or less melatonin. You can gradually increase or decrease your intake until you find the right amount, but do not exceed 10 mg, the maximum recommended daily serving.

The chart below can help you determine when to take melatonin and how to identify your body’s reaction to help find the right amount for you. Melatonin for kids may differ so consult your pediatrician for specific questions.

Side Effects Of Melatonin In Children

When starting any new vitamin, supplement, or medication, it is important to weigh the risks beforehand. Although more studies need to evaluate risks of taking melatonin long-term, reported side effects in children and adolescents include:

  • Increased bedwetting

Because melatonin is a hormone, some health professionals have suggested that taking it as a supplement could interfere with a childs development. However, several studies have shown no adverse effects in reproductive function or child development.

Melatonin may also interact and interfere with other herbs, supplements, and certain medications. A childs doctor should be aware of any supplements or medications the child is currently taking before they start melatonin.

Schizophrenia And Bipolar Disorder

Animal and in vitro data

In an in vitro study involving olfactory neuroepithelial cells, the investigators suggested that low levels of melatonin during pregnancy may increase the risk for developing schizophrenia due to impairment in neuronal polarization and axonal formation in neuronal precursors.

In a murine model of schizophrenia, melatonin administration reversed ketamine-induced social interaction deficits, memory deterioration, and changes in brain antioxidant activity, and reduced ketamine-induced hyperlocomotion. Melatonin’s ability to counteract ketamine-induced behavioral changes was better than haloperidol and comparable with olanzapine. Melatonin significantly improved brain oxidative stress compared to both haloperidol and olanzapine.

Side Effects Of Melatonin

The Influence Of Melatonin And Agomelatine On Urodynamic

Like any other dietary supplement, melatonin may cause side effects in some peoplepossible side effects include:

Dr. Bollu says drowsiness can mean either excessive sleepiness at night or grogginess the next day. He also adds that interfering with your bodys natural sleep cues may carry another side effect as well.

Taking a hypnotic medication regularly, on a nightly basis, would dampen your innate drive to sleep, explains Dr. Bollu, who adds that although we dont know for certain, this could also be true for melatonin. However,some research suggests melatonin may not dampen this drive in the same way that Ambien, for example, does. When your body recognizes more melatonin in the body, it begins to slow down its own production of melatonin over time. Therefore, short-term use of a melatonin supplement is preferred.

If you experience hypothermia, shortness of breath, chest pain, high blood pressure, or an accelerated heart rate, seek emergency care.

Melatonin For Sleep Problems In Special Populations

Attention-deficit hyperactivity disorder :

Children with ADHD suffer from dysregulation that commonly includes sleep problems. As well, medications used to treat ADHD may increase sleep difficulties.

One study evaluated the efficacy of sleep hygiene and melatonin in a group of 27 children from six to 14 years of age with ADHD. Participants receiving stimulants had insomnia defined by a sleep latency of at least 60 mins. All children were given a sleep hygiene intervention. Five children responded with an improvement to < 60 mins of delay in onset of sleep. The nonresponders then participated in a 30-day, double-blind crossover trial of 5 mg melatonin. During the study phase of melatonin treatment, there was a decrease in the mean time to onset of sleep from 91 mins to 31 mins.

Autism spectrum disorder :

Up to 67% of autistic children have been reported to have sleep difficulties. One double-blind, crossover, random control trial involving 11 children from five to 15 years of age with ASD and a sleep onset of at least one hour later than desired examined the efficacy of 5 mg of melatonin. Each treatment period was four weeks with a one-week washout between treatment periods.

There is also evidence that melatonin may be helpful in treating sleep problems in children with intractable epilepsy , neurodevelopmental disabilities , and with Angelman syndrome .

Melatonin Dose By Weight

Melatonin is a hormone produced naturally in the body. Melatonin supplements are best used when your body isnt producing enough melatonin, or when it is producing melatonin at the wrong times.

For that reason, using weight as a guide for your melatonin dosage is a bad idea. Its far better to understand how much youre producing naturally and when your melatonin surge is occurring. Whenever that surge occurs, youre going to start getting sleepy so its best to line up your melatonin surge with your bedtime.

Melatonin Dose For Toddlers

Most experts suggest using sleep training techniques to help toddlers, rather than providing a melatonin dosage.

If you have a child younger than 2 or 3 years old, you can attempt to induce a natural melatonin surge by making sure their rooms are dark at bedtime, which can be tough in the summertime. Also, avoid letting your toddler watch TV or use devices like tablets or smartphones 30 minutes to an hour before bed.

One last thing you can try to help your toddler create melatonin is to let natural light enter his or her room when its time to get up in the morning.

Delayed Sleep Phase Syndrome And Melatonin

Is melatonin safe to help children sleep?

Delayed sleep phase syndrome is a common disorder in teens, where their natural sleep period is shifted significantly later than the schedule which their commitments mandates. Thus, teens with this disorder an unable to fall asleep by 12 AM in the morning or even later. I have seen kids who are routinely falling asleep between 45 AM. Melatonin has a clear role in this disorder, as small doses 34 hours earlier than sleep onset can be effective in managing this disorder. The reason for the delay is a marked delay in the DLMO, so melatonin dosing can move sleep periods earlier. For children with DSPS, giving a dose 46 hours prior to the current time of sleep onset, then moving it earlier every 45 days, is recommended, with low dose preparations. Of all the conditions mentioned here, this has the clearest benefit from melatonin. Here is a terrific review article.

My Child Is Already On Melatonin Do I Need To Freak Out

I dont think so, as there is little concrete evidence of significant harm. However, if you started melatonin on your own I beg you to discuss it with your childs physician to see if it is really necessary. If your child has been using it long-term and sleeping well, you can consider slowly reducing the dose and seeing if it is still really necessary. Try to use it as needed as opposed to nightly. Also, I would take a hard look at sleep hygiene and ensure that you are ensuring good bedtime processes such as a high quality bedtime routine and avoidance of screen time for at least an hour prior to bedtime. I would try to reduce the dose, and potentially only use it as needed as opposed to nightly.

Please do take measures to keep melatonin in a safe place and dose it appropriately. For more on melatonin safety, including reducing overdose risk and avoiding interactions with other medications, read this article.

May Alleviate Migraine Attacks

A migraine attack is a recurring type of headache that causes severe, throbbing pain or a pulsing sensation, often on the side of your head.

Several prescription drugs help treat migraine, but melatonin may also offer relief due to its ability to inhibit pain sensations .

In a review of 11 studies, taking melatonin significantly reduced migraine severity and frequency compared with a placebo in both children and adults, but with varying effectiveness .

A different review of 25 studies found similar results, suggesting that taking 3 mg of melatonin at bedtime reduced migraine frequency in adults .


Melatonin may support eye health, ease tinnitus symptoms, treat acid reflux and GERD, and alleviate migraine attacks, but stronger evidence is needed for these uses.

Melatonin For Kids: What To Know

17 melatonin for kids uses side effects and dosage melatonin

Melatonin supplements are marketed to parents as a safe, effective, drug-free, non-habit-forming sleep aid for kids. It sounds like a godsend, but don’t give melatonin without careful consideration and the approval and guidance of your child’s doctor.

Melatonin is a hormone that our bodies produce in varying amounts throughout the day and night. It affects our internal clock , and therefore our sleep cycles. Our bodies produce more melatonin after dark, peaking in the middle of the night and dropping just before morning.

The research on melatonin as a sleep aid in children isn’t solid yet. Many of the studies are small, haven’t used standardized terminology or measures , and often contain biases.

Still, many studies show that taking melatonin supplements may help some children fall asleep more quickly and sleep longer. These studies have mostly been done with children who have conditions such as Autism Spectrum Disorder or Attention Deficit Hyperactivity Disorder , which can make sleep difficult.

One study of 125 children and adolescents with ASD, for example, showed the use of prolonged-release melatonin resulted in sleep that was about an hour longer at night. It also decreased the amount of time needed to fall asleep by 40 minutes, without causing an earlier wakeup time.
