Researchers arent certain which dose of melatonin is most effective. It has been studied at doses ranging from 0.3 mg to 10 mg. It is possible for a small dose to work better than a large dose. A dose of about 0.3 mg closely resembles the level of your bodys natural melatonin production. Larger doses cause the melatonin in your blood to peak at a much higher level.

Taking a typical dose may elevate your blood melatonin levels to 1 to 20 times normal.

    Side Effects of Melatonin: What Are the Risks?

    Dear Mayo Clinic:

    Is it okay to give my teenage daughter melatonin to help her sleep better? I have read that it’s a safe alternative to sleep medicines.


    Although melatonin has been shown to be useful for treating sleep problems in adults, it has not been carefully studied in children. Due to the lack of scientific evidence, and because of some potentially harmful side effects, melatonin is not recommended as a sleep aid for children and teens. Making lifestyle changes that can enhance healthy sleep is a better alternative for most people your daughter’s age.

    Melatonin is a hormone produced by your brain’s pineal gland. Melatonin appears to be linked to the body’s sleep/wake cycle, or circadian rhythm. The release of melatonin is stimulated by darkness and suppressed by light. The levels of melatonin in your blood are highest just before you go to sleep.

    Some research suggests that, in adults, melatonin supplements might be helpful in treating jet lag or reducing the time it takes to fall asleep. The most common side effects from taking melatonin are daytime sleepiness, dizziness and headaches. Less common side effects can include abdominal pain, mild anxiety, irritability, confusion and feelings of depression. It is not known how common or severe these side effects might be in children.

    Melatonin Side Effects: The Pros & Cons of This Natural Sleep Aid

    When consuming most supplements and medicines, a few side effects are possible.

    However, unless otherwise indicated, possible, does not mean such effects are at all likely.

    For example, if a side effect is described as common, it means it only effects one in 10 to one in 100 people, and if it is described as uncommon, it will affect between one in 100 and one in 1,000 people.12

    For example, headaches are common when taking melatonin, but you still have less than a 10% chance of getting one.

    Dizziness, abdominal pain, and nausea are uncommon, so you have less than a 1% chance of those side effects.13

    The chance of side effects happening does increase if you take too much of the supplement or medicine, or if you use it in the wrong way, or in conjunction with other medicines or remedies.14

    If you get a mild side effect, you then have a choice as to whether or not the side effect is worth the benefits of taking the supplement or medicine.

    If you do not consider that it is worth it, you can usually stop taking the medicine and then consult with a professional about alternatives.

    In the case of melatonin, there are no problems with stopping it when you want to.

    Do seek help though if you think you have had a serious allergic reaction to a medicine, or see a general practitioner if you experience a side effect that you think is severe.15

    What Is The Appropriate Dosage Of Melatonin

    There is no consensus about the optimal dosage of melatonin although most experts advise to avoid extremely high dosages. In studies, dosages range from .1 to 12 milligrams . A typical dose in supplements is between one and three milligrams, but whether this is appropriate for any specific person depends on factors like their age and sleeping problems. You may find melatonin in dosages of micrograms , 1000 mcg is equivalent to 1 mg.

    Some people experience daytime sleepiness when using melatonin as a sleep aid. If you experience this, it could be that your dosage is too high. Its advisable to start with the lowest dosage possible and work your way up gradually under the supervision of your doctor.

    The AAP advises against dosages above 3-6 mg for children and states that many young people respond to small doses of .5 to 1 mg. Some studies have found benefits to lower doses in adults as well.

    Oral supplements can bring the levels of melatonin in the blood to levels much higher than is normally produced by the body. For example, dosages between 1-10 mg can raise melatonin concentrations to anywhere from 3 to 60 times typical levels. For this reason, people taking melatonin should use caution before ingesting high doses.

    When To Steer Clear

    Certain people should be more cautious about melatonin use, particularly if it triggers a negative reaction, including those with:

    • Chronic insomnia. Having trouble falling asleep or staying asleep that lasts a month or more shouldn’t be managed with melatonin, according to the American Academy of Sleep Medicine and the American College of Physicians. These groups recommend other more proven remedies , noting that there is not enough evidence that melatonin is safe and effective for long-term use.
    • Restless Legs Syndrome . The tingling or “creepy-crawly” feeling in the legs that often keeps people awake could be worsened by melatonin. The supplement can intensify RLS symptoms because it lowers the amount of dopamine in the brain, according to the Restless Legs Syndrome Foundation. If you’ve been diagnosed with RLS or suspect that you have the condition, talk to your HCP about lifestyle changes or medications that could help.
    • Dementia. This progressive cognitive deterioration is often associated with insomnia, which can tax both patients and their caregivers. But melatonin may do more harm than good among those with dementia since the condition causes people to metabolize the supplement more slowly, resulting in daytime drowsiness. In people with moderate or severe dementia, melatonin supplementation may increase the risk of falls, according to 2015 guidelines from the American Academy of Sleep Medicine.

    If you’ve been drinking alcohol, it’s also not safe to take melatonin.

    The Melatonin Side Effects You Should Know About

    Yes, it could cause insomnia.

    If youre like the 88 percent of women regularly not sleeping through the night , youve probably found yourself looking for alternatives to counting sheep.

    Last year, the National Institutes of Health reported that 3.1 million Americans used melatonin supplements to fall asleep. Melatonin is a natural hormone secreted by your brain that helps regulate your circadian rhythm, or when your body wants to wake up and go to sleep, says Jocelyn Cheng, M.D., a neurologist at NYU Langone Health.

    Studies have actually shown that melatonin can help people with sleep disorders fall asleep anywhere between 27 and 50 minutes faster.

    But before you go buy out your local vitamin shop’s stock, remember: A supplement is not a regulated drug, so theres always a question as to whether youre getting what it claims to be, warns Rachel Salas, M.D., a neurologist with a focus on sleep disorders and sleep medicine at Johns Hopkins Medicine.

    One study actually found that 71 percent of melatonin supplements did not meet the claims on the label, with some listing up to five times the amount of the hormone than it actually contained. Look for supplements displaying seals from the United States Pharmacopeial Convention or NSF International so you know the manufacturers are legit.

    Of course, like any drug or supplement, melatonin can come with some side effects.

    How Much Melatonin Should I Take And Can I Take It Every Night

    Effective doses of melatonin for sleep are generally low, says Dr. Grandner. The literature suggests that between 0.5 mg and 3 mg is all it takes to have a significant biological effect, especially if taken in the early evening. The effects are essentially the same, no matter the dose, especially in this range. Taking a slightly higher dose closer to bedtime may also help, though there is less data on this. Higher doses are generally not recommended unless in special situations. If you take too much, you may find that it does not work, or at least it does not work any better than a low dose. You will often have more side effects, though, from headaches and nausea to dizziness and grogginess.

    Reasons To Be Cautious About Melatonin

    Your sleep-deprived friends may swear by it and you’ve probably read about it online or seen it on drugstore shelves. But is melatonin all it’s cracked up to be, or are you better off just counting sheep to get some ZZZs?

    First, the basics: Melatonin is a naturally occurring hormone in the brain that your body uses to help regulate your circadian rhythm. That’s the 24-hour body clock that, among other vital functions, tells you when to sleep and when to wake up each day.

    Your body gradually starts making melatonin about two hours before bedtime, bringing on that familiar drowsy feeling, and production continues throughout the night. In fact, melatonin is often called the “Dracula of hormones” because levels rise when it gets dark outside. As sunrise approaches, levels begin to drop, letting you know it’s time to rise for the day.

    Given melatonin’s essential role in the body’s internal clockworks, many people assume the supplement is safe. This may be one reason why it has become the fourth most popular supplement among U.S. adults, according to a National Health Interview Survey. Its use doubled between 2007 and 2012, as more than three million adults reported taking the sleep aid.

    And it is true: Melatonin is generally harmless – at least if you take it for a short period of time.
