Should I Take Melatonin For Sleep

Sharing is caring!

If you cant fall asleep night after night, its no wonder that youre looking for a sleep aidand as awareness grows about the addictive nature and side effects of sleeping pills, one natural supplement has nearly become a household name: melatonin.

Taking melatonin to help sleep, of course, is nothing new. But a problem I see is that so many clients are interested in natural sleep aidswithout understanding when, how much, and who should take them.

With products flooding the market like melatonin gummies Reddit threads advising dosage and how much melatonin you should take, and even questions about if dogs and kids can take melatonin, its safe to say theres a lot you may not know about taking melatonin.

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.

Melatonin Sleep And Adhd

Melatonin is a hormone that is naturally produced in the brain in response to darkness. It helps our bodies maintain healthy sleep-wake cycles, where melatonin essentially tells the brain, Its time to start getting to sleep.

The ADHD brain, however, has a delay in melatonin onset. Research shows that the onset of melatonin for most adults is roughly 9:30 pm, but in adults with ADHD it happens more than an hour later. In children with ADHD, the melatonin onset is similarly late around 10:15 pm.1

This delay in melatonin onset is also associated with late sleep onset the time it takes for children and adults with ADHD to fall asleep. It typically takes a neurotypical person up to two hours to fall asleep after melatonin onset. In adults with ADHD, it may take three hours.2

Melatonins delayed onset helps to explain, in part, why people with ADHD often experience sleep problems. Research shows that 25 to 50 percent of people with ADHD have a sleep disorder34.

Taking melatonin as an ADHD supplement under the guidance of a pediatrician or primary care physician, therefore, can help children and adults with ADHD get to sleep safely and naturally.

What Are The Symptoms Of Melatonin Overdose

Remember, symptoms of melatonin overdose vary from one person to another, which means identifying them correctly might be a bit tricky. However, this is the list of symptoms that might appear in case you take more than 20-50mg:

  • Confusion
  • Vomiting
  • Weakness

Except for the symptoms on this list, melatonin overdose may also cause your blood pressure to drop beyond normal. If you have high blood pressure, nerve or liver disorders, it is best to get pre-screened before including melatonin supplementation in your daily routine.

Emilys Take:

Before I was introduced to melatonin and the way it works, my primary concern was its lethal dosage. What I wanted to know was if there is a dosage of this supplement that could kill me so I could stay far, far, far away from it.

What I learned is that every single medicine on the market has its own LD 50. LD 50 is the lethal dose of the substance, an amount that kills at least 50% of the experimental animals it was tested on.

Melatonin is relatively safe, and your life wouldnt be seriously endangered even if you took 100 times higher dose than recommended, as such high doses werent enough to cause death in a single mouse.

How Else Can You Improve Your Sleep Quality

“Melatonin works synergistically with other practices,” says Dr. Dow. “You’ll get the best results by combining a melatonin supplement with simple sleep hygiene strategies like keeping a consistent bedtime, exposing yourself to natural light first thing in the morning, and keeping the bedroom very dark and cool.” That includes avoiding blue light, so no scrolling through your phone or staring at the clock.

Most importantly, you’ll want to seek medical guidance to find the root of your insomnia. “As a sleep clinician, I first ask why is this person not sleeping?” Dr. Singh says. “That’s the fundamental thing.” Mental health and quality sleep go hand-in-hand, and melatonin alone can’t fix those kinds of issuesnor can it cure chronic, long-term insomnia. So, if you think you need to take melatonin everyday, don’t. Instead, talk to your doctor about more effective strategies and treatments for long-term relief.

Is Melatonin Safe For Children

Nearly 25% of children have difficulty sleeping, and parents increasingly turn to melatonin for help. Between 2007 and 2012, pediatric melatonin use rose seven-fold and is now the second most common natural supplement in this age group. However, further research is needed regarding the safety of melatonin for children.

There are reasons for parents to be cautious about the patchy data on melatonin in kids. It appears that children may be particularly vulnerable to the possible effects of this supplement on reproductive hormones. Melatonin has been associated with puberty delays, irregular menstruation, and overproduction of the hormone prolactin. It is important to note, however, that research on this topic is conflicting, and experts agree that the topic is understudied.

Parents should also be aware that melatonin may . Children taking other medications or who have illnesses affecting these systems should consult their doctor before starting melatonin.

Melatonin should only be used for children under the guidance of a doctor. Most pediatric sleep disorders can be managed with behavioral changes, such as proper sleep hygiene and cognitive therapy. Melatonin should not be used before trying other measures.

Do Electronic Devices Alter Melatonin Levels

Light at night blocks the production of melatonin, and this has been shown to cause sleep disturbances in people who use electronics that emit light at night. Researchers have found that light from electronic devices can block the release of natural hormone melatonin at night. The effect was most significant for younger children, with nighttime levels reduced by up to 37 percent in certain cases. This can also be problematic for children between ages 9 and 16.

Studies show that light after dark lowers melatonin levels which may lead to difficulty in initiating sleep. Electronic light-emitting devices such as the television, laptops, smartphones and tablets often find their way into the bedroom at night, or are used after dark. Children should not have electronics, including TVs, in their bedroom at bedtime and everyone should avoid use of light-emitting devices and screen time at least one hour before bedtime.

How Much Melatonin Can You Take Safely? The Natural Sleep ...

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 2 to 3 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. Consumers should look for products labeled United States Pharmacopeial Convention Verified for the most reliable formulation.

Melatonin Supplements: What Do I Need To Know

Melatonin produced by our body is called endogenous melatonin, however, it can also be produced externally and is available as a dietary supplement. It is available as a pill, capsule, or liquid. Melatonin supplements may be helpful in certain situations for both adults and children. There is no consensus about an optimal dose of melatonin. It is best to avoid extremely high dosages for prolonged periods.

In general, it is relatively safe up to 10 mg, says Bhanu Prakash Kolla, MD, co-chair for education, Department of Psychiatry and Psychology, Associate Professor of Psychiatry and Psychology, and Consultant for the Center for Sleep Medicine and the Division of Addiction Medicine at the Mayo Clinic College of Medicine in Rochester, Minnesota. If you take a melatonin pill, it is not the pineal gland you are getting it from, but the supplement. We see it as a gentle sleeping pill.

You can buy melatonin over-the-counter as a sleep aid and since its considered a supplement and not a drug, melatonin is not regulated by the U.S. Food and Drug Administration.

The supplements are generally considered not habit-forming and they dont leave you in a hangover fog as some prescription sleep medications can. Melatonin works for short-term sleep problems, like jet lag or a wonky sleep schedule from working the graveyard shift, and for those who have trouble falling asleep and staying asleep.

What Most People Get Wrong About Melatonin

Since the rest of us arent doctors, we probably shouldnt be self-administering melatonin, and one of our experts agrees. The most common error is dosing, says Dr. Kolla. People confuse insomnia, a difficulty falling asleep, with circadian rhythm disorders. For circadian disorders, you want to take a smaller dose and take it about an hour before your desired bedtime to give more time to set the body clock. If taking as a sleeping pill, take it 30 minutes before bedtime.

Always check with your doctor before introducing a supplement to your routine, but better yet, bring in the exact bottle of melatonin youd like to try to get his or her OK first. This is important because a recent study shows that the melatonin content of dietary supplements often varies widely from what is listed on the label.4The Journal of Clinical Sleep Medicine reported that the contents in 30 different commercial melatonin supplements varied greatly, and some even had serotonin in them, without being mentioned on the labels.5 Serotonin regulates mood and memory among other physical processes in the body and can have a very real effect on your mental health.

Based on available studies and clinical use, melatonin powder is generally regarded as safe in recommended doses. That means only for kids older than age 10, in doses of three mg or less, for short-term use. But because you probably can, doesn’t mean you should use melatonin.

But, if you insist on melatonin for your kid, start it a day or two in advance to get the desired effect.
