What Taking Melatonin Every Night Really Does To Your Body
When it comes to supplements that claim to help you sleep better, one reigns supreme: melatonin. According to WebMD, more than 3 million adults and nearly 500,000 children took it in 2018. By 2020 Americans were spending more than $825 million on melatonin supplements annually .
Melatonin is actually a hormone produced by the brain’s pineal gland in response to darkness. It helps ground your circadian rhythm and tells the body that it’s time to wind down for sleep. Supplemental melatonin is usually made synthetically, though it can also be derived from animals or microorganisms . According to the National Sleep Foundation, there are no official dosage guidelines for melatonin, though most adults take between 0.5 and 5 milligrams. It’s best to take melatonin about an hour before bed and to start with a low dosage and only increase if you’re not seeing results. Additionally, melatonin is only meant to be taken short term.
But just how effective is melatonin for various sleep issues? Can it help with anything else besides a good night’s rest? Is it really as harmless as people think it is?
The Bottom Line Short
Melatonin is a hormone naturally produced in the body to promote sleep, and taking additional melatonin as a supplement can help boost this effect. There are no serious side effects or significant risks associated with taking a small dose of melatonin before bed occasionally, or for a few weeks. However, because the long-term side effects havent been studied, you shouldnt take melatonin every night for more than a month or two.

Are Melatonin Supplements Safe To Use
Melatonin supplements are largely considered safe, but there are some things to keep in mind. The fact that its a supplement means that its not regulated by the Food and Drug Administration . The label may say melatonin but the bottle may not have any functional melatonin, warns Bradley Vaughn, MD, professor of sleep medicine and epilepsy at the UNC School of Medicine. To make sure youre getting what youthinkyoure getting, look for supplements with a seal that saysUSP Dietary Supplement Verified. The United States Pharmacopeia is a highly trusted third-party laboratory that rigorously tests supplements to ensure that they contain exactly what the label says.
You should also talk to your doctor before starting melatonin supplements theyll confirm that its safe based on your medical history, conditions and other medications. Like all supplements, melatonin can interfere with certain medications. Specifically, melatonin can interfere with certain anticoagulants, diabetes medications and immunosuppressants.
Still Not Sure How To Properly Start Taking Melatonin Every Night
If you still have questions on how to proceed, you can use a simple strategy used by nearly everyone that tries melatonin for a few weeks.
- Start with the minimum dose
- Take it 90-60 minutes before bedtime
- Try to relax and see whether it works for you or not
- Increase the dosage to no more than 1.5 milligrams
This is the best strategy that you can use. Sometimes, depending on whats causing your sleep problems, melatonin will not work for you. In this case, its always good to go see a doctor to determine the root of your problem.
Most of the time, its either stress or a hormonal problem.
Now, again, you should not take melatonin every night for more than a few months. If you do decide to do so because its doing wonders for you, the best thing to do is to consult a doctor.
Its a good idea to get some tests done to make sure its not harming your body long-term, although there arent any majorly bad side effects from taking melatonin.

Can I Take Melatonin In The Middle Of The Night
Taking melatonin after you have already been asleep for a while, and wake up in the middle of the night can be done, but is not advised at all!
When you take melatonin mid-sleep cycle, you are almost surely going to wake up more groggy and tired than ever before. While it can help you get back to sleep, the hopes of a restful nights sleep are side lined by these negative side effects.
Waking up fully rested is out of the question for most people who attempt this. So, can you take melatonin in the middle of the night? Sure, but be ready to pay for it.
My advice is to just take it the right way as I layed out earlier in this article. Try some warm milk instead!

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.
Are There Any Side Effects Of Melatonin Supplementation
As long as youre taking an appropriate dose of melatonin between one-half and three milligrams for most people, and never more than five milligrams its very unlikely that youll have any serious side effects. However, Vaughn says that certain less-serious side effects are fairly common: headache, upset stomach and worsened mood throughout the day.
Taking more than five milligrams per day can lead to more side effects. Higher doses can cause plasma concentrations to rise three to 60 times normal peaks and produce various side effects like daytime sleepiness, increased prolactin levels, hypothermia and impaired physical and mental performance, Ghassi explains. She also points out that theres a lack of research on the safety of melatonin for pregnant and breastfeeding women, so its best for women in those groups to avoid it.

Choose Your Melatonin Supplements Carefully
Just because the label lists how much melatonin each pill contains doesn’t mean that’s actually what’s in the bottle. A 2017 study published in the Journal of Clinical Sleep Medicine examined the actual contents of 31 melatonin supplements and noted that “melatonin content was found to range from 83% to +478% of the labelled content.”
Melatonin, along with all dietary supplements, falls into a regulatory gray area. The Food and Drug Administration doesn’t have the authority to review the safety or effectiveness of dietary supplements before they’re put on the market. It’s up to manufacturers to ensure that their products are safe and contain the quantity and quality of ingredients they claim to have.
If you want to ensure the melatonin you’re taking is on the up-and-up, look for bottles with the USP Verified label. The United States Pharmacopeia program is an independent certification program that evaluates the quality of dietary supplements. If you see the label on a bottle, you can be assured that the product contains the listed ingredients in the amounts and potency claimed. The USP Verified label also indicates that a product doesn’t contain harmful levels of certain contaminants, such as mercury, lead, and pesticides. It also certifies that the supplement breaks down in the body in the way and at the speed it’s supposed to. Finally, the USP label denotes that the product was made according to the FDA’s Good Manufacturing Practices.
Is Melatonin Safe For Kids
The U.S. Food and Drug Administration has not approved melatonin for use in children and adolescents with insomnia and other sleep disorders. However, some doctors do recommend melatonin for children sleeping poorly. Use of melatonin in children is called off label, or using a drug for a purpose or group of people other than what is officially recommended.

Melatonin Dosage For Older Adults
Our melatonin levels naturally , disrupting the sleep-wake cycles for many older adults. As a result, older adults may have an increased sensitivity to melatonin. In a meta-analysis of 16 studies, melatonin dosages between 0.1 milligram and 50 milligrams per kilogram were administered to older adults aged 55 to 77 years old. In all of the studies, the melatonin levels remained higher among the older adults when compared to younger adults and stayed higher for a longer period of time leading to increased daytime drowsiness. The more melatonin the person took, the more pronounced these effects.
As a result, researchers recommend older adults start with the lowest dose of melatonin possible. Lower doses may help older adults sleep better without disrupting their circadian rhythms and causing prolonged drowsiness.
Older adults with dementia should avoid melatonin, according to the American Academy of Sleep Medicine.
Regular Vs Extended Release
When you think of melatonin, youre likely thinking of a regular pill that instantly releases melatonin into your body. However, extended-release melatonin pills, sometimes called slow- or time-release pills, allow the melatonin to dissolve in your body gradually.
Extended-release melatonin mimics natural melatonin production in your body, and for people who wake up throughout the night, its particularly helpful in keeping you asleep and helping you fall back asleep.

Are Certain People More At Risk When Combining Alcohol And Melatonin
Yes. Certain groups of people are more at risk for complications from alcohol, melatonin, or the combination of both.
People taking certain medications
People taking the following prescription and OTC medications at higher risk for problems when combining with either alcohol or melatonin:
-
If you take blood thinners, such as warfarin , alcohol stops your body from properly digesting the medication and could lead to serious bleeding, such as stomach bleeding or a brain bleed. A small study also suggested melatonin could have a similar effect on blood thinners.
-
If you have anxiety and use melatonin to help you sleep, consuming alcohol along with anxiety medications, such as alprazolam , can be dangerous to mix with alcohol because the combination can cause life-threatening drowsiness or trouble breathing.
-
If you take other OTC sleep aids, such as valerian root, diphenhydramine , or doxylamine , you should avoid both alcohol and melatonin. This combination can lead to more severe drowsiness and a higher risk for accidental injuries.
This is not a complete list of medications that interact with alcohol or melatonin. Please speak with your provider to discuss if other medications you take are safe to combine with these substances.

Can I Take Melatonin With Alcohol
Because melatonin is something our bodies naturally make, its no wonder that many people ask whether its safe to drink alcohol and take a melatonin supplement within a few hours of each other. While there are no studies exploring how alcohol affects melatonin supplements, both typically cause drowsiness, so mixing them could lead to more severe sleepiness.
As mentioned earlier, alcohol disrupts our sleep-wake cycle, and natural melatonin promotes it. Drinking alcohol could also counteract a melatonin supplements effects, making it harder for it to do its job.
In short, melatonin will work best when there is no alcohol in your system.

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.

Will A Melatonin Supplement Interact With Other Drugs Or Supplements

How Do You Take Melatonin For The First Time
To start, take melatonin 30 minutes before bed. You can adjust the timing depending on how long it takes for you to fall asleep. What’s most important is that you avoid taking melatonin at or after your ideal bedtime. This can shift your body clock in the wrong direction, resulting in daytime sleepiness.
Liver Or Kidney Conditions
If you have any concerns with your liver or kidneys, dont take melatonin unless youve consulted with your doctor and received the OK. Melatonin is metabolized by the liver and excreted from the body via the kidneys. So, if you have pre-existing conditions that affect either of these organs, your body may struggle to break down and remove melatonin from your body.

First Off What Are Melatonin Sleep Aids
Before answering the question “can you take melatonin every night?” you need to know what, exactly, you’re consuming. Melatonin is a hormone produced by your brain’s pineal gland in response to darkness, and in people who have a healthy circadian rhythm, levels naturally peak between 2 a.m. and 4 a.m. It’s then secreted into your blood and the fluid surrounding your brain and spinal cord and works to inhibit the stimulation of your suprachiasmatic nucleus, a tiny region in the brain that acts as a “master circadian clock” and tells your body to wake up or chill out. At that point, you’ll start to feel drowsy and ready for some shut-eye. “It helps bring on sleep, and it helps to entrain our circadian rhythm,” says Dr. Watson.
“There’s no real reason to take melatonin unless you have one of these disorders,” he adds. “It wouldn’t be recommended .” To treat difficulty falling asleep and staying asleep, the AASM advises clinicians not to use melatonin “because the overall evidence available was weakly against melatonin’s efficacy.” Not to mention, there are often more effective methods to treat the sleep troubles you’re experiencing. And that includes insomnia. “If you look at clinical guidelines around treatment for insomnia you’re not going to see melatonin really included,” says Dr. Watson. “It’s also not an FDA-approved treatment of insomnia.”
