Can You Take 20 Milligrams Of Melatonin

How Does Melatonin Help You Sleep

Can I take 20mg of melatonin?

Your body follows a circadian rhythm in which various physical, mental and behavioral processes are carried out depending on the time of day. In reaction to daytime and natural daylight, your brain releases the hormone serotonin, which regulates your mood, appetite and memory. At night, in response to darkness, your brain switches off serotonin and starts releasing melatonin. This hormone helps calm your body down and prepare for sleep by making you feel tired or drowsy.

Once that sun goes down, your melatonin system turns back on and a couple hours later, your melatonin levels are high enough for you to be able to fall asleep, explains Dr. Roth. This is why in some places, like Ohio, our energy levels are lower during the winter because we dont have a lot of natural sunlight during the day. So, were not as energetic, and we never quite get that burst of melatonin production at night.

Work With Not Against Melatonins Sleep

Melatonin levels rise about two hours before bedtime, Buenaver says. Create optimal conditions for it to do its job by keeping the lights low before bed. Stop using your computer, smartphone or tabletthe blue and green light from these devices can neutralize melatonins effects. If you watch television, be sure youre at least six feet away from the screen. Turn off bright overhead lights too. Meanwhile you can help program your body to produce melatonin for sleep at the right time of day by getting exposure to daylight during the morning and afternoon. Take a walk outside or sit beside a sunny window.

Melatonin is a very popular sleep aid. Its naturally produced in your body. You dont need a prescription for it and can buy it in gummy form or in a fruity drink. But is it as effective and safe as we think?

Natural melatonin, a hormone produced by the pineal gland, helps humans fall asleep and synthetic melatonin has been available as a sleep aid for nearly three decades. But the synthetic versions effects have not been extensively studied, and since its classified as a dietary supplement, it is almost completely unregulated by the FDA.

Its important to take a closer look at this common supplement. Any person in the sleep world will tell you the same thing: melatonin is not harmless, is vastly overused and should not be used as a sleep aid to treat insomnia, Michael Grandner, a sleep researcher at the University of Arizona, told HuffPost.

How Much Melatonin Is Too Much

It’s hard to say exactly how much melatonin is too much since there is no standardized dose, but it’s best to start with the lowest dose possible and work up from there, says Alex Dimitriu, MD, founder of Menlo Park Psychiatry and Sleep Medicine in Menlo Park, California.

There is no known lethal dose of melatonin and no reports of death from taking too much melatonin, Dimitriu says, but taking too much can disrupt your natural circadian rhythm and internal body clock, causing you to actually have more trouble falling asleep.

What the research says: Some studies have shown that cancer patients can benefit from large doses of melatonin ranging from 20mg to 1,000mg, but these doses are generally not recommended for those with no underlying medical conditions.

The effects of taking large doses of melatonin don’t appear to be lethal, Dimitriu says, but more research is needed to determine the long-term health implications of melatonin use and the effects of doses larger than 30mg.

Melatonin is an indispensable molecule found in most plants and living organisms. As an antioxidant, anti-inflammatory, and anti-cancer agent, it contributes to a wide range of functions within the body. Yet melatonin is still best known for its role in improving sleep and reducing jet lag.

Which Type Of Melatonin Supplement Should I Take

Time isn’t the only factor to help determine how melatonin supplements will affect your sleep. Both the dosage and type of supplement you take can lead to vastly different experiences, Ju says.

Consider, too, that nutritional supplements like melatonin aren’t subject to the same regulations as medications, she says. With this in mind, researchers conducted a study in 2017, comparing different brands of melatonin supplements including tablets, gummies, liquids and more.

“They found that the dosage that’s present inside the actual melatonin pills doesn’t always match what’s on the label,” Ju says. And some supplements even included serotonin which may interfere with a person’s sleep, according to the study.

“When I counsel my patients, I recommend to them that they get at least a three-milligram-sized tablet,” Ju says. “And if they’re trying it for the first time to actually cut it in half and try 1.5 milligrams.”

Melatonin, when dosed correctly, will not make you feel groggy or lead to deep sleep that makes it difficult for you to wake up, she says. In general, a dose between one to six milligrams is typically used for adults, and anything above that doesn’t usuallyprovide additional benefits.

What Are Melatonins Side Effects On Kids

Potential, though mild, side effects of melatonin use in children include agitation, headache, dizziness and drowsiness. While it is not known for sure and more research on the long term use of melatonin in children is needed, its important to remember that melatonin is a hormone, and, as such, there is a possibility that it may affect hormonal development, including puberty and menstrual cycles.2

The Bottom Line

If your child occasionally has trouble falling asleep, instilling better sleep habits and routines might be in order. But if your child experiences significant difficulty falling asleep, melatonin might benefit, especially when its used in combination with behavioral interventions and healthy sleep practices.5

Most importantly, talk with your childs pediatrician before giving them melatonin to make sure its right for them, to understand the proper dosage, and to rule out any underlying health issues.

Use Melatonin Sleep Supplements Wisely And Safely

Less is more, Buenaver says. Take 1 to 3 milligrams two hours before bedtime. To ease jet lag, try taking melatonin two hours before your bedtime at your destination, starting a few days before your trip. You can also adjust your sleep-wake schedule to be in sync with your new time zone by simply staying awake when you reach your destinationdelaying sleep until your usual bedtime in the new time zone. Also, get outside for natural light exposure. Thats what I do, Buenaver says.

How Do Melatonin Supplements Work

Melatonin may not be as safe as you think

The pineal gland in the brain is responsible for natural melatonin production in the body. It doesnt make you sleepy, but as melatonin levels rise in the evening, it puts you into a state of quiet wakefulness that helps promote sleep, explains Johns Hopkins sleep expert Luis F. Buenaver, Ph.D., C.B.S.M.

Taking melatonin can help with a range of sleep problems such as:

  • Primary sleep disorders like insomnia
  • Delayed sleep-wake disorder
  • Sleep problems in children with autism spectrum disorder or attention deficit hyperactivity disorder

When’s The Best Time To Take Melatonin Before Bed

Before deciding the best time to take melatonin, you should make one clear distinction, says Ju.

Knowing whether or not you have a circadian rhythm disorder will dictate how close to bedtime you should take a supplement. Folks with a delayed circadian phase are commonly referred to as night owls.

“For people who have a problem with their internal clocks, if they have a circadian disorder, like a night owl type, we will recommend that those individuals take melatonin about an hour or two before their desired bedtime,” she says.

But, most people don’t have a circadian disorder and those who are taking the supplements solely to get to sleep, “can take it at bed time or just 15 minutes prior,” Ju says.

What Are The Side Effects Of Melatonin

“While many studies have examined melatonin, the side effects aren’t firmly established,” says Dr. Ramkissoon.

The most commonly reported melatonin side effects include:

  • Daytime sleepiness

“Certain studies also report short-term feelings of depression and irritability, as well as stomach cramps,” adds Dr. Ramkissoon.

Lastly, since supplements aren’t regulated by the FDA like over-the-counter and prescription medications are, you’ll need to do some research to be sure you’re getting a quality product that has undergone testing and been certified by an independent third-party laboratory, such as NSF.

For instance, a 2017 study testing more than 30 different melatonin supplements found that the amount of melatonin in the product often didn’t match what was listed on the label, and that some products contained ingredients other than melatonin. These are issues that can affect the side effects a person experiences, as well as the product’s overall safety.

Why Do People Take Melatonin

Melatonin is the hormone released by our brains once we fall asleep and it is actively used to handle a range of different conditions. Apart from the regular sleep-related ones, melatonin is also known for being particularly useful in various cancer treatments as an additional ingredient to use through chemotherapy, for instance.

Alcohol can disrupt your natural melatonin levels, so experts recommend against taking melatonin when drinking or when using other sleep medications.

There is limited evidence that melatonin might be helpful in recovering from alcohol use disorders due to the antioxidant effects of melatonin. However, more research needs to be done.

Because melatonin supplements arent medications, they arent regulated by the U.S. Food and Drug Administration . Theres no guarantee about the quality of the product youre purchasing or the quantity of ingredients claimed on the label, unlike prescription drugs. A pharmacist or nutritionist may be able to help you find a product produced by a reputable manufacturer.

How Long Does It Last

The plasma half-life is quite short and ranges between 20 and 50 minutes. This means that approximately only half of the dose remains in your system after this amount of time. This means that while it may help you fall asleep faster, it likely wont help you to stay asleep or increase the quality of your sleep.

What Is The Right Dosage Of Melatonin: How Much Is Too Much

How Much Melatonin Should I Take

Knowing how much melatonin to take is tricky, especially since some brands may recommend a dosage thats more than your body actually needs.

As you shop around, youll find that some melatonin supplements contain as much as 5 to 10 milligrams per serving.

Generally speaking, most people produce enough melatonin to sleep well. If you need a little extra to reset your sleep cycle, you probably dont need more than 3 mg. Some people sleep better with as little as 0.3 to 0.5 mg.

Melatonin needs vary from person to person. Since melatonin can have many effects on the body, like all drugs, it should be taken at the lowest dose possible, warns Dr. Jacobowitz.

With that being said, start with a low amount. If you still have problems sleeping, gradually step up your dose until you find an amount that improves sleep without causing side effects.

Less is more with melatonin to avoid sleep inertia. This is a common problem with some sleeping pills. Some people complain of a hungover or groggy feeling in the mornings due to remnants of the sleep aid remaining in their bloodstream.

This effect doesnt typically occur with melatonin, but it can happen if you take too much the night before.

Melatonin is also safe for children. And like adults, some children dont need a lot of the supplement to sleep better.

Again, start your child at a lower dose, and then gradually increase the amount of melatonin as needed. Talk to your doctor for advice on appropriate dosages.

In adults, 10 mg is the maximum recommended dosage. However, most people do not need doses of melatonin this high. While there is no risk of addiction, research shows that melatonin administration is effective at the lowest dose for the short term. Doses of melatonin in the range of 1 mg to 5 mg can help promote good sleep quality and normal circadian rhythms . If sleep problems persist after taking supplemental melatonin for 1-2 weeks, you should consult a sleep specialist.

What Are Signs Of A Melatonin Overdose

If you deal with insomnia, you might do anything for relief. Melatonin is a popular go-to sleep aid because its natural and has a low risk of unwanted side effects.

But while side effects are less common with melatonin compared with other sleep aids, you may experience a few if you overdose and take too much.

There dont appear to be any reports of people dying from overuse of melatonin. But while overuse might not cause death, it can cause a few of the below symptoms:

Theres also the threat of rebound insomnia when theres too much of the hormone in your system. Melatonin may stop working after a while, and your sleep problems could even worsen.

How Melatonin Works

Melatonin is produced by the pineal gland, when the retina at the back of the eye registers darkness. However, melatonin production is reduced and risk of disease potentially increased by exposure to artificial light. Hence recommendations to discontinue use of night-lights, and to reduce time in front of the computer and TV at night, especially since these produce more blue light than red light, which is more detrimental to melatonin production.

How To Take It

Melatonin 20mg (Capsules)

There is currently no recommended dose for melatonin supplements. Different people will have different responses to its effects. Lower doses appear to work better in people who are especially sensitive. Higher doses may cause anxiety and irritability.

The best approach for any condition is to begin with very low doses of melatonin. Keep the dose close to the amount that our bodies normally produce . You should only use the lowest amount possible to achieve the desired effect. Your doctor can help you determine the most appropriate dose for your situation, including how to increase the amount, if needed.


  • Always ask your child’s doctor before giving melatonin to a child. In fact, doses between 1 to 5 mg may cause seizures in this age group.


  • You should work with your doctor to find the safest and most effective dose for you. The right dose for you should produce restful sleep with no daytime irritability or fatigue.
  • Jet lag: 0.5 to 5 mg of melatonin 1 hour prior to bedtime at final destination has been used in several studies. Another approach that has been used is 1 to 5 mg 1 hour before bedtime for 2 days prior to departure and for 2 to 3 days upon arrival at final destination.

How Much Melatonin Is Safe To Take

Melatonin is available to purchase in any quantity, without a prescription in the U.S. However, there is currently no formal consensus on the optimal dosing regimen for this supplement. Studies frequently use doses ranging from 0.1 to 10 milligrams, but 1 to 5 milligrams is often considered an appropriate amount to start.

There are many challenges to determining the appropriate amount of melatonin for any one person to take. Individual responses to this supplement can vary considerably due to factors that are not fully understood but can include age, gender, specific sleep issues, other health conditions, and timing of administration.

In addition, not all melatonin supplements are created equal. Differences in preparation can significantly alter melatonins impact. Depending on the formulation, taking 1 to 10 milligrams of melatonin can raise the bodys melatonin blood levels anywhere from 3 to 60 times the normal amount.

Melatonin users should also be wary of the dosages listed on supplement labels, which have shown to be alarmingly inaccurate. A random sampling of 31 brands of melatonin supplements determined that most did not contain the labeled dose, with the actual amount ranging anywhere from less than 80% to nearly 500% as much. Additionally, over one-quarter of the supplements contained serotonin.
