Does Melatonin Help Rem Sleep
Melatonin may increase REM sleep. The REM sleep. stage is also when your brain has its best chance of dreaming. After taking melatonin and falling asleep, you may experience longer & more vivid dreams. Having dreams after taking melatonin is completely normal and is a sign that the melatonin is working.
While youâre sleeping, the melatonin in our Vicks ZzzQuil PURE Zzzs Melatonin Gummies will begin to wear off. Your brain will move from the REM cycle into the deep sleep cycle during which you will sleep through any minor sleep disturbances . From the deep sleep cycle, youâll move into the light sleep cycle.
Itâs very important to let your brain get to the light sleep stage, as waking from the REM or deep sleep cycles will leave you disoriented and tired, regardless of whether you took melatonin or not. The light sleep cycle prepares you to wake by increasing your body temperature and decreasing your natural melatonin. This decrease in melatonin tells your body that itâs time to wake.

Which Type Of Melatonin Supplement Should I Take
Time isn’t the only factor to help determine how melatonin supplements will affect your sleep. Both the dosage and type of supplement you take can lead to vastly different experiences, Ju says.
Consider, too, that nutritional supplements like melatonin aren’t subject to the same regulations as medications, she says. With this in mind, researchers conducted a study in 2017, comparing different brands of melatonin supplements including tablets, gummies, liquids and more.
“They found that the dosage that’s present inside the actual melatonin pills doesn’t always match what’s on the label,” Ju says. And some supplements even included serotonin which may interfere with a person’s sleep, according to the study.
“When I counsel my patients, I recommend to them that they get at least a three-milligram-sized tablet,” Ju says. “And if they’re trying it for the first time to actually cut it in half and try 1.5 milligrams.”
Melatonin, when dosed correctly, will not make you feel groggy or lead to deep sleep that makes it difficult for you to wake up, she says. In general, a dose between one to six milligrams is typically used for adults, and anything above that doesn’t usuallyprovide additional benefits.
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.

How Long Does Melatonin Stay In Your Body
Melatonin doesnt last in the body for long. It has a half-life of 40 to 60 minutes. The half-life is the time it takes for the body to eliminate half a drug.
Typically, it takes four to five half-lives for a drug to be fully eliminated. This means melatonin will stay in the body for about 5 hours.
If you stay awake during this time, youre more likely to feel aftereffects like drowsiness. Thats why its recommended to avoid driving or using heavy machinery within 5 hours of taking it.
But remember, everyone metabolizes drugs differently. The total time it takes to clear will vary for each person. It depends on several factors, including:

What Are Melatonin Supplements
The brain normally makes only a very small amount of melatoninaround 0.2 milligrams, Brandon Peters-Mathews, MD, a sleep medicine specialist at Virginia Mason Medical Center in Seattle, told Health. For some people, that might not be enough to help them get the rest they need. So melatonin supplements, which typically contain higher doses than the amount your body naturally releases, can be useful to treat sleep disorders and insomnia.
“Supplemental melatonin allows us to get drowsy and ready for sleep,” Dr. Malow said. “In addition, melatonin can be calming and help us ‘turn our brains off.”
Research backs this up, according to the National Center for Complementary and Integrative Health , showing that melatonin supplements can help individuals dealing with conditions such as:
- Delayed sleep phase wake disorder
- Pre-surgery anxiety
- Some sleep disorders for children
MedlinePlus says that melatonin supplements can be taken orally, but they are also available in the form of creams, gargles, and gels. Additionally, a melatonin supplement may be slow- or fast-release.
Additionally, melatonin is a prescription medication in Europe. However, in the US, it qualifies as a dietary supplement, meaning it’s available over the counter without a prescription at drugstores and health-nutrition retail outlets, and the U.S. Food and Drug Administration does not regulate melatonin very strictly, per the NCCIH.

When To See Your Doctor
There have been no cases of harm in overdose with melatonin. If you have taken more melatonin than it said on the label, you might become very sleepy. Stay somewhere safe, with a friend or family member to watch you while you sleep off the effects. Tell your doctor or pharmacist as well. It should take about 12 hours for your body to deal with the extra doses. Do not try to drive or do anything that could be dangerous to yourself or others.
Stop taking melatonin and go to a doctor straight away if you get any of the following symptoms:
- fainting or losing consciousness
- dizziness or vertigo
- feeling mixed up and confused
- severe chest pain, or changes in heartbeat
- a flaky pink/red rash on your skin, particularly on your elbows and knees, called psoriasis
Taking Melatonin For Jet Lag
Jet lag happens when you travel across time zones. For a few days after you’ve traveled, your body’s internal clock will still be set to where you came from, not where you arrived. This can make you tired and you may have trouble focusing.
Research has shown that melatonin may help you get over jet lag symptoms. In fact, the American Academy of Sleep Medicine supports using melatonin to reduce jet lag and sleep better when you’ve been traveling across more than one time zone.

Is It Bad To Take Melatonin Every Night
Regardless of whether it truly helps with sleep or not, Dr. Ramkissoon doesn’t recommend taking melatonin long-term.
“Namely, because if you think you need to take melatonin every night to get to sleep, we need to understand why that’s the case,” explains Dr. Ramkissoon.
Is poor sleep caused by a lifestyle habit that needs correcting or some underlying issue that needs to be addressed?
“Melatonin isn’t a long-term fix for sleep issues,” Dr. Ramkissoon adds. “If you’re consistently suffering from insomnia, we need to determine why and find an effective solution for it.”
What’s more is that the safety of using melatonin long-term hasn’t been established in well-controlled studies.
And while the occasional, short-term use of melatonin such as to combat jet leg or adjust to shift work does appear to be safe for most people, this isn’t the case for everyone.
Don’t take melatonin if you’re pregnant or breastfeeding. And know that these supplements can interact with other medications, such as some blood thinners, and that they may not be safe to take if you have certain health conditions.
“It’s always important to consult your doctor before taking a new supplement,” adds Dr. Ramkissoon.
Factors Affecting How Long Melatonin Lasts
But how long does melatonin last in your system? Melatonin typically stays in your system for around four to eight hours, but this range largely depends on external factors, including:
- Age: Your metabolism slows as you age, meaning the rate at which your body can metabolize the melatonin also slows. The older you are, the longer it may take for melatonin to wear off.
- Caffeine: Research has shown that caffeine can modify melatonin production to counteract the effectiveness of the supplement.
- Light exposure: Exposure to bright light, especially the blue light emitted from technology, can send signals to your brain that its daytime, making it harder for the melatonin to take effect.
- Body size: Factors like your height and weight impact how you absorb melatonin and how it affects you.
- Tobacco use: In animal studies, nicotine has been shown to inhibit melatonins effectiveness in the body.
- Other medications: Additional medications like blood thinners, immunosuppressants, and stimulants may counteract the effectiveness of melatonin.

Know The Potential Side Effects
Possible known side effects of melatonin include feeling groggy or dizzy after taking it or when waking up the next morning. The effect may be more pronounced with larger doses, which can lead to melatonin levels that are not only much higher than normal in the evening, but may also linger into the morning, Martin said.
Won added that older people might be more susceptible to this hangover effect and waking up still drowsy. But experts said these symptoms are generally mild and go away once people stop using the supplements.
Additionally, some people report having strange, vivid or intense dreams while taking melatonin. One theory is that the hormone appears to somehow be related to REM sleep, which is the phase of sleep in which most dreaming tends to occur, experts said.
How Long Does It Take For Melatonin To Work
Usually, melatonin begins to kick in between 20 minutes and 2 hours after consumption. This is why it is advised to take melatonin 2 hours before bedtime.
Natural melatonin production increases 2 hours before bedtime. Sleeping at the same time consistently signals your body when its time for melatonin production.
There is no fixed answer to how long does it take for melatonin to work. Its different for different people.

Tolerance Dosage And Precautions
Melatonin is well tolerated in children. Although theres some concern that long-term use may delay puberty because a natural decline in evening melatonin levels is associated with the onset of puberty more studies are needed .
Melatonin supplements for children are often sold in the form of gummies.
Dosage varies by age, and more research is needed to determine the optimal dosage and effectiveness. Nonetheless, common recommendations are 1 mg for infants, 2.53 mg for older children, and 5 mg for young adults .
Additionally, because researchers dont yet understand the long-term effects of melatonin use in children, it may be best to help your kids implement good sleep practices if those are not already in place before you give them melatonin (
Older adults should be sure to talk with a pharmacist or doctor before taking melatonin.
Summary
Melatonin levels naturally decrease as you get older. Supplementing with low doses may help improve sleep quality in older adults.
How To Get The Best Results
Light is the switch that controls when your brain makes melatonin. When you take a supplement, take care that you donât disrupt its effects with artificial light:
- Avoid your phone and other tech devices that shine brightly in the hours before bed.
- Turn off overhead lights in the evening.
- Bright light in the morning can signal itâs time to wake up.

How Melatonin Works
The body has many different 24-hour or daily cycles that regulate everything from cellular metabolism to insulin function and hormone secretion, says Grandner. The main function of melatonin, from a circadian perspective, is to signal the body that its nighttime.
The main function of melatonin, from a circadian perspective, is to signal the body that its nighttime.
Unlike many other sleep aids, melatonin is not a sedative. Its a hormone that our bodies produce at night. Supplements can boost our natural levels and help get our body clock on track.
How Does It Work
Melatonin supplements may improve sleep by boosting melatonin levels in people whose bodies do not produce enough of this hormone.
These supplements may also improve sleep in people who produce enough melatonin but still struggle to sleep for other reasons.
Melatonin changes how the body responds to darkness, helping it enter a rhythm of nighttime drowsiness.
Exposure to light at night including light from computer and television screens may suppress the bodys natural melatonin production and disrupt sleep.
Likewise, people who sleep during the day because they work at night may not produce melatonin when it is time to sleep. Melatonin supplements can help counteract this effect.
Research consistently shows that melatonin can help people sleep longer and fall asleep more quickly.
Although melatonin is a natural chemical, it is important to treat it the same as any other medication. It is possible for melatonin to interact harmfully with other drugs by reducing their effectiveness, triggering negative side effects, or changing the way that the body metabolizes the drug. People who take other medications should talk to a doctor before trying melatonin.
As with any medication, an allergic reaction is possible. People with a history of allergic reactions to supplements should avoid melatonin.

Is It Safe To Take Melatonin Every Day And Are There Any Side Effects
Both Dr. Peters-Mathews and Dr. Malow believe melatonin is generally safe to take every night, but large studies are needed to determine whether its effective and safe for all forms of insomnia and particularly for long-term use. Melatonin is used safely by most people for years, says Dr. Peters-Mathews.
Dr. Peters-Mathews recommends sticking to lower doses of melatonin to prevent unwanted side effects, which typically include increased dreaming, nightmares, or morning sleepiness. If you are bothered by these side effects, you should stop taking melatonin and speak to your doctor about alternatives.

What Are The Side Effects Of Melatonin
“While many studies have examined melatonin, the side effects aren’t firmly established,” says Dr. Ramkissoon.
The most commonly reported melatonin side effects include:
- Daytime sleepiness
“Certain studies also report short-term feelings of depression and irritability, as well as stomach cramps,” adds Dr. Ramkissoon.
Lastly, since supplements aren’t regulated by the FDA like over-the-counter and prescription medications are, you’ll need to do some research to be sure you’re getting a quality product that has undergone testing and been certified by an independent third-party laboratory, such as NSF.
For instance, a 2017 study testing more than 30 different melatonin supplements found that the amount of melatonin in the product often didn’t match what was listed on the label, and that some products contained ingredients other than melatonin. These are issues that can affect the side effects a person experiences, as well as the product’s overall safety.
