Does Melatonin Work for Insomnia? A Doctor Answers

by Edward R. Rosick, D.O., M.P.H.

melatonin for insomniaDid you get a good night’s sleep last night?

Most of us have insomnia every now and then. About 60 million Americans have trouble sleeping frequently or for extended amounts of time, according to the National Institute of Neurological Disorders and Stroke. And drug cures are plentiful. They’re also mostly short-lived and sometimes a little too good to be true.

But there may be an alternative.


Sleeping Pills and Side Effects

For short-term sleep problems, doctors often prescribe benzodiazepines (such as Ativan, Valium and Xanax) and other similar medications. While these do help people sleep, they’re not a cure for insomnia. Many prescription and over-the-counter pills tend to lose their effectiveness after a couple of weeks, can be habit-forming and can actually interfere with a good night’s sleep by reducing the time you spend in deep sleep. For people who want to try an alternative, the answer may be the supplement melatonin.

Melatonin is a hormone produced in a structure called the pineal gland, which is deep within our brain. While there’s still a lot to learn about it, researchers have shown that it’s intimately connected with sleep.

During the day, melatonin levels are low; when darkness falls, they increase significantly. Since we know that melatonin is part of the sleep/wake cycle, many integrative-medicine doctors recommend it as a sleep aid, touting it as a more “natural” way to help people beat insomnia.

Does the Melatonin Supplement Work for Insomnia?

Melatonin does have a few studies backing its effectiveness, though they’re not particularly large or conclusive. In 2005, researchers analyzed data from 17 small studies. Their findings, published in Sleep Medicine Reviews, concluded that melatonin can make you fall asleep about four minutes faster, increase your sleep efficiency by about 2 to 3 percent and add around 13 minutes to your sleep duration.

Melatonin use may be especially relevant to elderly people. As people grow older, sleep problems become more common. Since melatonin levels decline as we age, it makes sense to think that supplements could help seniors get a good night’s sleep.


Melatonin Side Effects and Dosage
Melatonin doesn’t appear to be habit-forming, lose its effectiveness or interfere with normal sleep. It’s apparently safe for most people in the short-term but hasn’t been studied in the long-term. Dosages vary widely. A good starting point seems to be 0.3 milligrams. (You can cut a 1-milligram tablet into thirds).


As a physician specializing in holistic medicine, I try to educate my patients on what supplements are safe and effective, as well as which ones are worthless and possibly dangerous. For people looking for a natural alternative for insomnia, melatonin appears to be a good choice to help them get a good night’s rest.

I swear by it!
written by Ashley , October 05, 2011

I have tried tyenol PM, advil PM and every other OTC medicine you can think of. Melatonin works wonders for me. I take 5-10mg a night. Usually an hour before bed. On the other hand...my friend has taken up to 20mg at night and it did nothing for her. I did read somewhere that it will only work for you if your melatonin levels in your body are low.

Hey Paris...to me it sounds like you suffer from mind awake sleep paralysis. I have the same thing. Do a little research online about it. It's pretty interesting.

Re: Melatonin queries

Hello, Paris. We can't give individual advice, but in general, I'd say if you weren't having these before the melatonin, talk to your psychologist. He may want to alter the dose or stop it altogether.

Used it before
written by drkej , June 25, 2011

I've had hit or miss results with melatonin. Try taking it after a big dinner and it doesn't help with indigestion and actually kept me up at night. Then I tried taking it with a very light dinner but my problems with frequent urination still kept me awake. This same case held true for some other "herbal" sleep remedy I tried, Simply Sleep. Then I tried out Tylenol PM on and off and like any other medication, its effectiveness wears off after awhile.

Melatonin has improved the quality of my sleep.
written by Dave , May 27, 2011

When I was in my mid 40's, lack of sleep was affecting my performance during the day. I would toss and turn all night and could never get a good night's sleep. This lack of sleep made me forgetful and had a hard time focusing on things. A friend of mine suggested that I try melatonin before going to bed at night. I read up on it a bit, and decided to try it. The very first night, I dozed off quickly. I went into a deep sleep like I hadn't experienced in years. I was actually dreaming again (something I hadn't done for a long time). I woke up feeling almost numb all over because I had finally had a good nights sleep. I've been taking melatonin every night ever since. I'm now in my mid fifties and still sleep like a baby using melatonin. I think the key is to find the correct amount to take. These days, they sell low dose pills so you don't have to cut them up anymore. But one thing's for sure, studies or not, this stuff has changed my life for the good. If you're a space cadet during the day because you aren't sleeping well at night, give this stuff a try.

I've tried melatonine
written by Dima , March 11, 2011

Hi! my name is Dima, and I just wanted to know, Is it supposed to work on EVERYONE? i've tried it for weeks now, and not only I get no results when going to bed, but I feel weird changes on my budy during the rest of the day. It feels tired, and heavy for the first hours in the morning. Now that i think about it maybe it has nothing to do with melatonine, but with the fact that im in my twenties and it may work better on older people.

This article was very helpful, Ill keep on doing research regarding this matter now.
