![]() You could experience nausea or a headache. It’s unlikely that you’ll suffer any serious side effects if you take a large dose of melatonin, but you may not feel so great, either, says Grandner. The researchers concluded the supplements improved the sleep of 47 out of 51 children enrolled in the study and produced an average total sleep time improvement of 30 minutes. A 2019 review that only included studies of adults at least 65 years old concluded that those participants benefited from using between 1 milligram and 6 milligrams of melatonin a night.Ĭhildren on the autism spectrum (ages 2 to 18) with delayed sleep: One study in the Journal of Pineal Research gave children with autism 5 milligrams of controlled-release (or time-release) melatonin each night. Here’s a sample of what the research says:įor adults who who have trouble falling asleep at a conventional bedtime (delayed sleep phase syndrome): A 2010 review in Sleep found studies that administered 0.3 milligrams to 5 milligrams of melatonin nightly with participants concluded that melatonin made a positive impact on total sleep time and sleep onset.įor adults who have sleep problems caused by beta blockers (high blood pressure medication): A 2012 study in Sleep found that 2.5-milligram capsules of melatonin taken one hour before bedtime each night increased participants’ total sleep time by 36 minutes and decreased the time it took them to fall asleep by eight minutes.įor adults 65 and older with sleep disturbances: Natural melatonin production can wane with age, leading to more sleep issues as you get older. You may have to experiment with timing and a higher dose, though. If you flood the body with an extremely high level of melatonin, he warns, there’s a chance your body will simply override it, treating it like an error signal.įor this reason, he suggests patients try taking half a milligram of melatonin about one to two hours before they would normally go to bed. Grander advocates for low doses of melatonin to trick the body into believing the supplement is a natural signal-meaning the body mistakes the supplement for your body’s own natural production of melatonin. ![]() Indeed, the American Academy of Sleep Medicine says that melatonin may be used for some problems related to sleep timing, but it’s not a solution for a serious sleep issue like chronic insomnia. Melatonin supplements are best for someone with mild sleep issues, he says. Grandner says melatonin supplements may improve the ability to fall asleep faster for some people, but how much will be slight, measured in minutes-not hours. “Melatonin may help someone fall asleep a bit faster and it may help them stay asleep during the night, but a lot of supplement manufacturers overpromise.” “Melatonin doesn’t work like a prescription sleeping pill. Melatonin is commonly used as a sleep remedy, but people often misunderstand it, says Michael Grandner, M.D., director of the sleep and health research program at the University of Arizona College of Medicine in Tucson. They’re available over the counter in the U.S., though you need a prescription in many other countries to obtain them. Melatonin supplements (called exogenous melatonin) are generally synthetically produced hormones. ![]() Endogenous melatonin-melatonin found naturally in the body-is supposed to help make you increasingly sleepy as the evening sets in and bedtime approaches. The pineal secretes melatonin in response to reduced light. Melatonin is a hormone produced in the body by the pineal gland, a tiny gland found deep in the brain.
