Q: How Much Melatonin Should I Take To Help Me Sleep

A: Taking the sleep hormone melatonin is recommended to help induce sleep, but there is a good deal of confusion about how much to take. It is sold over the counter in a range of doses, from 1 mg to 10 mg and higher. The natural inclination is to take more melatonin if it is not effective in helping you sleep better, but this is not a good idea. ;

The hormone serotonin is produced during the day and this changes to melatonin when it gets dark outside. Peak levels of melatonin are produced before 3 a.m., when it sharply decreases before natural daylight returns. ;

Research has found that taking melatonin in low doses is the most effective way to promote sleep if you are experiencing restlessness or insomnia. Recommended doses of melatonin are from 0.5 mg up to 3 mg, which are adequate to promote sleep or treat jet lag.

When melatonin is used at higher doses, it tends to increase daytime sleepiness. Other side effects of too much melatonin can include reduced focus and concentration, feeling chilled and higher prolactin levels.

If you find yourself taking higher doses of melatonin, you can decrease the dose by cutting your tablet in half or in quarters. Research indicates there are no side effects if you reduce the dose of melatonin you are taking.

Is Melatonin Safe To Take Every Night

Americans arent sleeping well. Roughly 80% of U.S. adults say they struggle to fall asleep at least one night a week, according to a recent Consumer Reports survey. And research has found that sleep problems are also on the rise among adolescents.

While the causes of Americas sleep woes are up for debate, theres little disagreement about Americas favorite remedy: Melatonin, the countrys most-used sleep aid.

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.

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.

Is Melatonin Safe Forchildren

Its no wonder parents are uncertain about this. If you surfthe web, youre likely to get mixed messages:

• Australian experts called the increase in use among children alarming and warned in 2015 that parents shouldnt give it to their children. WebMD
• Melatonin, according to more than 24 studies, is safe for children and has been used with little to no side effects. NaturalSleep.org
• Currently, we dont have any evidence to say that taking melatonin on a daily basis in that sense is harmful, although there are no large-scale multicenter clinical trials to really test that.Medscape

This last quote is probably closest to where we actuallyare. However, it is clear there has been a dramatic increase in use ofmelatonin in children in the past five years or so. For example, in England, estimates have found a 25percent increase in melatonin prescriptions in children under 18 between2015-16 and 2017-18, and a 40 percent increase in the extended release formsduring the same period. There are no similar statistics in the U.S. forover-the-counter melatonin, but it is now rare in our experience that childrencoming to the Boston Childrens Sleep Clinic with insomnia are not already onmelatonin, usually recommended by their pediatrician.;

Some kids, such as children with immune disorders or those taking immunosuppressants, should not take melatonin at all. While melatonin is generally well-tolerated in adults, further studies are needed to confirm its safety and efficacy in children.

Anatomical and physiological differences give rise to differences in the bodily absorption, distribution, metabolism, and excretion of drugs in children compared with adults. Many medicines, including melatonin, have only been tested for safety and efficacy in adults.

Several studies have shown melatonin supplements can significantly improve overall sleep times by 25 minutes to 48 minutes, on average, for children with these conditions.

However, there havent been enough studies of melatonin in children for experts to determine an official recommended dosage or any potential long-term safety risks. Since melatonin is a hormone, its possible that taking supplemental melatonin could affect other aspects of hormone development in children, but further research is needed.

If your child is having sleep problems, experts recommend consulting your doctor before giving them melatonin. Research indicates that for half of the cases where melatonin was used to treat pediatric insomnia, better sleep habits were just as effective at relieving the childs sleep problems.

How Much Melatonin Should You Take

The first thing you need to determine before landing on a melatonin dosage is why youre taking melatonin in the first place.

There are a number of different melatonin uses, and the reason why youre taking melatonin will certainly influence how much you should take. Your melatonin dosage will differ whether youre taking it for insomnia, jet lag, disrupted sleep-wake cycles, long-term sleeping difficulty or other reasons.

The perfect melatonin dose also differs between adults and children, as is explained below.

Alternatives To Taking Melatonin

If you have trouble sleeping, it is always wise to see a doctor.; A doctor can assess your symptoms and determine if a medical condition may be an underlying cause. If that turns out to be the case, your doctor can then identify treatment options that may also allow you to sleep soundly.

If you want a more restful sleep without melatonin supplements, start by establishing a sleep/wake routine. By following the same schedule nightly, you can create a pattern that your body gets used to, increasing the odds that youll be sleepy at the right time.

Avoid caffeine, alcohol, exercise and digital devices at least a few hours before bed. All of those things can disrupt your natural melatonin production, so forgoing them as the evening approaches can help. Anxiety can also hamper sleep. Finding natural ways to relieve stress can help.;

For some, herbal tea can promote better sleep. Some find consuming them relaxing, and that general sense of calm can make a difference.

Does Melatonin Work For Shift Workers

Shift work that involves night shifts may cause people to feel sleepy at work and make it difficult to sleep during the daytime after a shift ends.

According to two 2014 research reviews, studies on whether melatonin supplements help shift workers were generally small or inconclusive.

• The first review looked at 7 studies that included a total of 263 participants. The results suggested that people taking melatonin may sleep about 24 minutes longer during the daytime, but other aspects of sleep, such as time needed to fall asleep, may not change. The evidence, however, was considered to be of low quality.
• The other review looked at 8 studies , with a total of 300 participants, to see whether melatonin helped promote sleep in shift workers. Six of the studies were high quality, and they had inconclusive results. The review did not make any recommendations for melatonin use in shift workers.

Melatonin Dose By Weight

Melatonin is a hormone produced naturally in the body. Melatonin supplements are best used when your body isnt producing enough melatonin, or when it is producing melatonin at the wrong times.

For that reason, using weight as a guide for your melatonin dosage is a bad idea. Its far better to understand how much youre producing naturally and when your melatonin surge is occurring. Whenever that surge occurs, youre going to start getting sleepy so its best to line up your melatonin surge with your bedtime.

Most experts suggest using sleep training techniques to help toddlers, rather than providing a melatonin dosage.

If you have a child younger than 2 or 3 years old, you can attempt to induce a natural melatonin surge by making sure their rooms are dark at bedtime, which can be tough in the summertime. Also, avoid letting your toddler watch TV or use devices like tablets or smartphones 30 minutes to an hour before bed.

One last thing you can try to help your toddler create melatonin is to let natural light enter his or her room when its time to get up in the morning.

The Science Behind Melatonin

Melatonin , chemically N-acetyl-5-methoxytryptamine, is a substance found in animals, plants, fungi and bacteria. In animals, its a hormone that anticipates the daily onset of darkness.

In animals, melatonin is involved in the synchronization of the circadian rhythms of physiological functions including sleep timing, blood pressure regulation, seasonal reproduction and many others. Many of its biological effects in animals are produced through activation of melatonin receptors, while others are due to its role as a pervasive and powerful antioxidant, with a particular role in the protection of nuclear and mitochondrial DNA.

The hormone can be used as a sleep aid and in the treatment of some sleep disorders. It can be taken orally in liquid form as well as capsules or tablets in immediate- or prolonged-release form. It is also available in a form to be used sublingually, and as transdermal patches. Melatonin is sold as an over-the-counter sleep aid in the U.S. and Canada. In other countries it may require a prescription or it may be unavailable.
