Can I Take 10 Mg Of Melatonin

How Melatonin Affects Sleep

Is 10 mg of melatonin too much?

Melatonin makes a person feel sleepy through its effect on circadian rhythms, which are the near 24-hour cycles that affect every cell in the human body. One important circadian rhythm is the sleep-wake cycle, which affects when people fall asleep and when they wake up.

While the human brain naturally makes melatonin, supplements are also available in the U.S. over-the-counter. In some countries, melatonin supplements are only available with a prescription.

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

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.

How much melatonin is “too much” depends on your body and what it’s used to. One person may feel nothing after taking 3 mg of melatonin, while another could have a very strong reaction to the same dose.

The American Academy of Sleep Medicine says melatonin side effects may be more common at high doses . Common side effects include:

“Taking too much melatonin can have the opposite effect of its intended purpose,” says Daniel Powers, founder of the Botanical Institute with an MS in supplement formulation, safety, and manufacturing. “It can make it more difficult to sleep because your normal circadian rhythms will be disrupted.”

Your body can only digest melatonin so fast. For typical supplement doses of 1 mg to 5 mg, melatonin will stay in your system for four to eight hours. After your body has absorbed the supplement, your melatonin levels should return to your default amount.

If you take melatonin too late in the evening, or you take a very high amount, then the extra melatonin can spill over into the morning. Melatonin spillover can make your body think night is day and day is night. You may feel groggy while you’re awake and have trouble sleeping the next evening.

Melatonin Interactions And Warnings

Even though melatonin is sold over the counter , you should talk to your healthcare provider before taking it. This is especially true if you already take medication or supplements, or you have a medical condition.

Melatonin might change how your body processes some medicationsfor example, increasing or decreasing how much of a medication is in your system. Mixing medications with melatonin can also change how much melatonin is in your system.

If you are pregnant or breastfeeding, you should not take melatonin because there is not enough evidence to prove that it’s safe.

Side Effects Of Melatonin

Like any other dietary supplement, melatonin may cause side effects in some peoplepossible side effects include:

Dr. Bollu says drowsiness can mean either excessive sleepiness at night or grogginess the next day. He also adds that interfering with your bodys natural sleep cues may carry another side effect as well.

Taking a hypnotic medication regularly, on a nightly basis, would dampen your innate drive to sleep, explains Dr. Bollu, who adds that although we dont know for certain, this could also be true for melatonin. However,some research suggests melatonin may not dampen this drive in the same way that Ambien, for example, does. When your body recognizes more melatonin in the body, it begins to slow down its own production of melatonin over time. Therefore, short-term use of a melatonin supplement is preferred.

If you experience hypothermia, shortness of breath, chest pain, high blood pressure, or an accelerated heart rate, seek emergency care.

What Not To Take With Melatonin

Because melatonin can affect your sleep-wake cycle, avoid taking it with alcohol or caffeine. These can interfere with your circadian rhythm and your natural melatonin production.

Before starting melatonin or any over-the-counter medication or supplement, talk with your doctor. This is especially true if you take other medications.

For example, birth control pills may cause your body to produce more melatonin, so taking a supplement could push your levels into an unhealthy range.

Taking melatonin with anticoagulant drugs, such as warfarin , could increase your risk of bleeding.

You should also avoid taking melatonin if you take corticosteroids to suppress your immune response in conditions such as rheumatoid arthritis or lupus.

If you think you may have overdosed on melatonin, call Poison Control at 800-222-1222.

You should call 911 and seek emergency help if you have symptoms such as:

These signs may not be related to melatonin or an interaction between melatonin and other medications. However, they shouldnt be ignored, as they can indicate a medical emergency.

Though melatonin can be very helpful for some people needing a little extra help falling and staying asleep, its not for everyone. You may not tolerate it well, even at low doses. You may find that it doesnt help you sleep, regardless of the dose.

How Do Melatonin Supplements Work

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

Melatonin may also increase blood pressure in people who take medication to control their hypertension.

Other drugs that may interact with melatonin include:

Also dont take melatonin if youve been diagnosed with an autoimmune disease, like lupus.

Autoimmune diseases are the result of an overactive immune system, and inflammation is a classic symptom on these diseases. Melatonin can stimulate immune system activity, increasing inflammation and exacerbating an existing disease.

Are There Any People Who Should Avoid Taking Melatonin

Its also possible that your doctor will perform a physical exam and order blood tests. These can help them rule out a medical condition that may be causing your sleep issues.

  • Melatonin is a hormone your brain produces to help you fall and stay asleep.
  • Melatonin supplement use is increasing in the U.S., but its effectiveness as a sleep aide is still inconclusive.
  • While taking small doses of melatonin is safe for healthy adults, it is possible to overdose, especially for kids.
  • Signs of overdose include excessive sleepiness, vomiting and trouble breathing.

Over the past decade, more adults in the U.S. are taking melatonin supplements to help them get some sleep.

Melatonin is generally safe for short-term use, but further research is required to assess the long-term safety of melatonin use. In the United States, melatonin is considered a dietary supplement, which are regulated less strictly by the Food and Drug Administration than prescriptions and over-the-counter medications. Federal law doesnt require dietary supplements to be proven safe to FDAs standards before they are sold.

Furthermore, some melatonin supplements may not contain what is listed on the product label. Researchers tested 31 commercial supplements and found that most products contained far more or far less melatonin than what was listed on the label. Some supplements contained serotonin, a hormone that wasnt recognized on the product label.

Although melatonin is generally regarded as well-tolerated, it may not be ideal for long-term use, unless specifically instructed by your doctor. Supplemental melatonin shifts the phase of the human circadian clock, and thus warrants caution. The principle of treatment of sleep disorders is first to find the cause of the sleep disturbance, and then treat the conditions causing the distress.

Treatment options for primary sleep disorders, or sleep disorders that arent caused by another medical or psychological condition, often include behavioral therapies. Sleep hygiene, sleep restriction, stimulus control, relaxation training, and cognitive therapy are examples of such therapies.

Those Who Are Pregnant Or Breastfeeding

There is not enough information available on the side effects of melatonin supplements to determine if pregnant or breastfeeding people can safely take these supplements. Those who are pregnant or trying to become pregnant should avoid melatonin supplements unless directed by their physician. If you are struggling with sleep, ask your doctor for other ways to improve sleep during pregnancy.

How Much Melatonin Is Too Much

Itâs hard to say exactly how much melatonin is too much since there is no standardized dose, but itâs 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 donât 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.

Can I Take Melatonin With Caffeine

Caffeine is a stimulant, and billions of people consume it daily. Since it stimulates the central nervous system, it is likely to promote feelings of alertness in users.

Caffeine intake tends to lower the bodys melatonin production and thus can cause a disruption to your normal sleep-wake cycle. According to Sleep Foundation, this stimulant can delay sleep onset if a person consumes it before bedtime.

The combination might not be dangerous or fatal but could cause you to be increasingly alert. Note that melatonin is not a sedative. Thus, it may not have an antagonizing effect on caffeine as one might suppose.

However, depending on the dosage of caffeine consumed, the combination is most likely going to increase your alertness and annul the effects of the melatonin.

Work With Your Circadian Rhythm

As well as doing daily behaviors to help your body produce melatonin effectively, and avoiding ones that interfere with it, you can also take further advantage of your circadian rhythm. Thereâs a time when your brain will be naturally producing the most melatonin it will all night â in the RISE app, we call this the Melatonin Window. If you go to bed during this roughly one-hour window youâll have the easiest time falling asleep. But the timing of this window all depends on your circadian rhythm, which can change daily.

RISE predicts your circadian rhythm and gives you a one-hour window to aim to go to sleep each night. Line up your bedtime with this window, and itâll be like taking natureâs melatonin supplement.

What Is Melatonin And How Does It Work

Melatonin is a hormone that your brain produces in response to darkness. It helps with the timing of your circadian rhythms and with sleep. Being exposed to light at night can block melatonin production.

Research suggests that melatonin plays other important roles in the body beyond sleep. However, these effects are not fully understood.

Melatonin dietary supplements can be made from animals or microorganisms, but most often theyâre made synthetically. The information below is about melatonin dietary supplements.
