Is melatonin safe for kids?

By GyroscopeUpdated November 14, 20266 sources

Talk to your child’s doctor before giving melatonin. The American Academy of Pediatrics says to use it only after that conversation and once good sleep habits are in place, and there are no set dosing guidelines for children. Gummies, the most common form, often hold more than the label says.

This is general information, not medical advice. It sums up what pediatricians and the studies below say as of November 2026, and any worry about your own child’s sleep is a question for their doctor.

Melatonin is easy to see as harmless. Your child’s brain makes it every night, it’s sold next to the vitamins, and the gummies look like candy. But a supplement can put far more in the blood than the body makes, nobody checks the jar before it’s sold, and children’s hormones are still developing.

We’d put the routine first, the doctor second, and the jar up high. A regular bedtime, screens off well before bed, and a fixed wake time with morning light work on the same body clock melatonin does, without a pill. How to increase melatonin naturally explains how each one helps a body make its own.

Treat the jar like a bottle of children’s medicine. To a three-year-old it looks exactly like a bag of candy.

What to try first

The AAP puts good sleep habits first. The basics look like this.

• The same bedtime and wake time every day, weekends included.
• A short, calm routine before bed, the same every night.
• Screens off at least an hour before bed.
• Lamps instead of overhead lights in the evening, and daylight in the morning.

For teens, a fixed wake time on school days and weekends, plus time outside in the morning light, is the place to start.

What the research says

The US National Center for Complementary and Integrative Health describes a 2019 review of 18 studies in 1,021 children, many with conditions such as ADHD or autism. Melatonin helped them fall asleep sooner and sleep longer in the short term. The studies were small and brief, from 1 to 13 weeks, so nobody knows much about the best dose, the best time, or what years of use might do. Because melatonin is a hormone, it’s possible it could affect puberty and other hormonal development, and nobody knows for sure. Side effects reported in children have usually been mild, such as drowsiness, bedwetting, headache, dizziness and agitation.

The AAP notes there are no specific guidelines on melatonin dosing for children. Any dose for a child is a decision for their doctor.

The jar is the bigger risk

From 2012 to 2021, US poison centers got 260,435 reports of children and teens swallowing melatonin, and the yearly count rose 530 percent. 94 percent were accidents, 84 percent were children 5 or younger, and almost all happened at home. In emergency visits for young children from 2019 to 2022, gummies were the form most often recorded, and more than a third of those children had gotten into 10 or more gummies or tablets.

Gummies also aren’t reliable. In a 2023 test of 25 US melatonin gummy products, 22 didn’t match their label, from 74 to 347 percent of the stated amount.

Keep every jar up high and out of sight, with the lid closed. If a child swallowed melatonin, call Poison Control at 1-800-222-1222, and call 911 if they collapse, have a seizure, have trouble breathing or can’t be woken. What to do if your child ate melatonin gummies walks through it.
