Is It Safe To Take Melatonin Every Night
Unfortunately, theres no straight answer here, which youre probably hoping for. There isnt any evidence proving conclusively that long-term use of melatonin is safe. Though the supplement is generally not associated with dependency, habituation, or hangover symptoms, Dr. Kohli says she doesnt suggest taking melatonin every night because of the lack of long-term clinical trials; evaluating the safety of chronic use.
At the same time, there isnt any evidence proving nightly melatonin use isnt safe. Dr. Bollu points out that melatonin is a natural hormone that fluctuates in our bodies on a daily basis anyway, meaning it may be safer than taking a prescription drug.
However, thats a double-edged sword: 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.;
What Is A Safe Melatonin Dose
According to Michael Grandner, director of the Sleep and Health Research Program at the University of Arizona, melatonin is very safe if taken in normal doses, which is anything between 0.5 mg and 5 mg.
A 0.5 mg dose may be all thats needed for sleep-cycle regulation, and should be taken three to five hours before bed, he says. For people who want to take melatonin just before bed, a 5 mg dose is appropriate. Some people report headaches or stomach problems at higher doses, but those side-effects are uncommon, he says.
Still, there are other concerns. Melatonin has an incredible safety record, no doubt about it, says Dr. Mark Moyad, the Jenkins/Pomkempner director of preventive and alternative medicine at the University of Michigan. But its a hormone, and you dont want to mess around with hormones until you know what theyre doing.
People with existing medical problems should discuss melatonin with their doctor before using it. While some research has found that melatonin may help treat hyperglycemia in people with diabetes, for example, other studies have shown that, in diabetes patients who carry certain genetic traits, melatonin may interfere with glucose regulation. Its these sorts of contradictory findings that give experts pause when it comes to issuing melatonin a full-throated endorsement.

My Doctor And I Have Talked About It What Should We Consider Regarding How And When To Give Melatonin
Melatonin can be a tricky medication to dose. Effects change depending on when you give it compared to your childs usual sleep schedule. Thus, a small dose a few hours before bedtime can have more of an effect than a large dose given at bedtime. In some situations dosing may the opposite effect. This is a special case and should be addressed with your physician. A couple of rules of thumb.
- Timing: For shifting sleep schedules earlier 36 hours before current sleep onset is best. For the sleep onset effects, 30 minutes before bedtime is recommended. Remember, not every child gets sleepy with melatonin.
- Dosing: In general, I would start at a low dose and increase slowly. Recognize that melatonin, unlike other medications, is a hormone, and that lower doses are sometimes more effective than higher ones, especially if the benefit of it reduces with time.
- Good Sleep Hygiene is Critical: Melatonin is not a substitute for good sleep hygiene practices and should only be used in concert with a high quality bedtime, limitation on light exposure, and an appropriate sleep schedule.
- When possible, purchasing a USP Verified preparation;may indicate that the product is manufactured to the;requirements of the U.S. Pharmacopeial Convention, which could mean that the quality controllers are tighter.

And not much research has been done on whether its safe for children to take. However, recently, there has been some promising research showing that short-term use of melatonin is effective and well-tolerated in treating difficulty falling asleep in children and adolescents.3;Other research shows that melatonin may be especially helpful for children with conditions that can impact their ability to fall asleep, such as attention deficit hyperactivity disorder and autism.4 Melatonins use in these circumstances should be discussed and carefully monitored by your childs pediatrician.4

Studies have shown that exposure to supra-physiological plasma concentrations can lead to melatonin receptor desensitization.3,4 The range of maximally effective doses of exogenous melatonin was determined when the Massachusetts Institute of Technology first patented the medication. Since then, higher doses of up to 10 mg have been made available on the market. Although recent evidence suggests that doses greater than 6 mg of melatonin provide little benefit, additional research is required to determine the specific doses of melatonin that may be supra-therapeutic and subsequently interfere with the natural sleep-wake cycle or worsen insomnia from receptor desensitization.4 Appropriate monitoring and recommendations should be made to limit the dose being used on a regular basis in elderly people.3,4

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.
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 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.

Side Effects Of Melatonin
Like any other dietary supplement, melatonin may cause side effects in some peoplepossible side effects include:
- Nausea
- Dizziness
- Drowsiness
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.;
What Is The Best Melatonin Dosage
Studies suggest that 1-2 milligrams 30 minutes before bedtime is an optimal dosage of melatonin to help you fall asleep naturally for no next day grogginess*. Marketed sleep aid products may include melatonin levels as high as 10 mg, however, most healthy adults and kids who occasionally have trouble falling asleep benefit from a low dose of melatonin. ZzzQuil PURE Zzzs melatonin gummies are formulated to deliver a melatonin dosage of 1-2 mg, and manufactured under strict supervision.

- pregnant
Its a good idea to schedule an appointment with your doctor or healthcare provider if you notice that you:

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.
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.

Melatonin For Older Adults
The amount of melatonin your body produces decreases with age. Because of this, melatonin supplements may be helpful for older adults who are having trouble falling asleep.
Researchers are still looking into the optimal melatonin dosage for older adults. One 2016 review of sleep aids for older adults suggests a dosage of 1 to 2 mg of immediate-release melatonin 1 hour before bedtime.
When To Take Melatonin
Melatonin is naturally produced by the pineal gland in your brain to help you fall asleep. To regulate your sleep-wake cycle, i.e. your circadian rhythm, as the sun sets, your body begins to make melatonin, which causes you to feel sleepy. Towards morning, as the sun rises, your melatonin levels drop and histamine, cortisol and other neurotransmitters increase, which helps you awaken. But sometimes, your brain might not produce enough melatonin, or at the right time, and that impacts how easily you fall asleep and how well you sleep. When you add a melatonin supplement to your nighttime routine, 30 minutes before bedtime, you can give your body additional melatonin to help you fall asleep naturally.* For best results, use nightly and allow more than 6 hours of sleep.If you spend quite a bit longer than 20 minutes trying to fall asleep on a regular basis, consider trying a sleep supplement with melatonin in it .

Why People Take Artificial Melatonin
Since melatonin regulates the sleep cycle, individuals who suffer from sleep-related issues, like insomnia, may take artificial melatonin as a supplement. Similarly, travelers may use melatonin to reduce jet lag and adjust to a different time zone. Night shift workers may also take the supplement to make falling asleep during the day or at odd times easier.
When taken before bed, supplements increase the amount of melatonin in the body. This could make falling asleep or staying asleep easier. However, there is limited scientific evidence regarding the effectiveness of melatonin supplements, so it isnt clear whether people experience the purported benefits or simply a placebo effect.
As shown above, outside factors like sunlight can hinder your bodys production of melatonin. Supplements can bypass those factors and help you feel more ready to sleep, even if your environment is less than ideal.

Can You Overdose On Melatonin
While melatonin is generally considered safe, it is possible to take too much. There is no official recommended melatonin dosage, and people can have different sensitivities to melatonin, so finding an appropriate dose can be challenging. Moreover, because melatonin is not regulated in the U.S., the actual melatonin content of supplements can vary significantly. Studies have found that some melatonin products can have nearly five times as much melatonin as their label claims, or much less.
The first sign that youve taken too much melatonin is that youll continue feeling its soporific effects the following day. You may feel especially drowsy or groggy. Doses of 10 milligrams or higher can cause side effects like drowsiness and headache. Other symptoms of melatonin overdose include:
- Changes in blood pressure
- Vivid dreams or nightmares

There is good scientific evidence melatonin can shorten thetime to fall asleep in children with insomnia, including children with ADHD,autism and other neurodevelopmental disorders. While melatonin can be aneffective short-term solution to address bedtime problems, children withneurodevelopmental disorders may benefit from longer-term use in some cases. Itshould be noted that the immediate release formulation does not help withdifficulty staying asleep . There is some evidence to suggest that extended-releasemelatonin may help with night awakenings in children, but there are far fewerstudies to support this use, and the extended release formulations require theability to swallow capsules.
There are many reasons why children may have trouble fallingasleep: anxiety, restless legs symptoms or a too-earlybedtime are just a few. Before considering melatonin, have your pediatricianconduct a thorough evaluation for other potential causes.
In general, melatonin should not be given to healthy,typically developing children under age 3, as difficulties falling and stayingasleep in these children are almost always behavioral in nature.
