Melatonin for kids: Dosage, products, and safety

Melatonin for kids: Dosage, products, and safety

For most kids, some research indicates that melatonin is healthy. Scientists are also skeptical about the consequences of long-term usage, however.

To promote sleep and regulate the internal body clock, the body naturally produces melatonin at night.

To help with sleep issues, some individuals take a synthetic form. Synthetic melatonin is classified by the United States as a dietary supplement, rather than a drug.

We discuss the latest studies on the safety of melatonin and the most appropriate dosages for children in this article. We also mention some of the gummy and liquid melatonin products for children that are best tested.

Is it safe for kids to take melatonin?

A 2016 review of existing studies showed that in healthy children, melatonin tends to be safe and well-tolerated. However, no research has been conducted into the daily use of melatonin in children and the long-term effects of melatonin.

The authors of the analysis also advise that melatonin should be avoided in children with immune disorders or those receiving immunomodulatory therapy.

A meta-analysis of 13 studies in 2018 indicates that melatonin is safe for children with neurodevelopmental disorders, but more research is needed to support these findings.

Other research suggests that in children with autism spectrum disorder, melatonin can help sleep and have some other benefits.

However, as the National Center for Complementary and Integrative Health warns, hormonal development may be impaired by melatonin supplements. Still, there is too little evidence from studies in humans to confirm this finding.

Reports suggest that melatonin side effects are typically mild in children and may include:

  • feeling drowsy
  • dizziness
  • headaches
  • increased bedwetting or urinating in the evening
  • agitation

Dosages for children

Dosages for children
For infants, there is no known safe dose of melatonin.

It is important to remember that melatonin is regarded as a supplement rather than a medication by the Food and Drug Administration (FDA). As a consequence, the testing and safety regulations of a medication are not subject to melatonin. This suggests that the quality might not always be represented by the labeling of melatonin products.

An analysis of 31 melatonin supplements in 2017 showed, however, that none contained the amounts advertised on their labels.

Overall, talking to a doctor before giving melatonin to a child is the safest way. They can also provide guidance on the best dosages.

There is little research into the successful dosages of melatonin. A study published in 2016 found that no specific recommendations are still available and that different studies suggest different amounts.

As many kids seem to respond to doses in the 0.5–1.0 milligram (mg) range, it might be better to start with the lowest dosage.

It may be safe to raise the dose if this is unsuccessful. The dosages recommended by age are as follows:

  • 1 mg of melatonin for infants
  • 2.5–3.0 mg for older children
  • 5 mg for teenagers
  • For children with special needs, a dose that falls within a range of 0.5–10.0 mg

They also suggest that melatonin be given 30 to 60 minutes prior to bedtime.

Some other products can contain melatonin, such as relaxation tinctures or cough medicines, so be sure to check the labels of any other treatments or remedies before you are given melatonin.

Outside of the U.S., many countries categorize melatonin as a drug, and it is only available by prescription.

Creating an environment for sleep

The first and most important steps are identifying the root cause and maintaining proper sleep hygiene when addressing sleep problems.

For instance, it is vital to avoid exposure before bedtime to bright lights and lights from electronic devices, as these can block the body’s natural production of melatonin.

In addition, a 2014 study found that light suppresses the development of melatonin almost twice as much in kids as it does in adults.

Talk to a doctor if a child is having chronic sleep problems, as this can affect physical and mental health.


Research shows that, for healthy children as well as those with autism spectrum disorder and some health conditions, melatonin is safe in the short term.

At present, there is insufficient evidence to demonstrate the long-term effects of melatonin in infants, and some research suggests that hormone output may be impaired.

Discuss with a doctor any plans to use melatonin. As a short-term complement to improvements in sleep hygiene, they can suggest it.
