How Much Melatonin Should You Take
The right dose of melatonin for you is the lowest possible dose that can help you sleep with minimal side effects, Dimitriu says. This can vary by individual.
General advice: For most people, a melatonin dose of 0.5 to 5 mg can effectively help them fall asleep. If you find this dose isn’t effective, you can increase it from there under the guidance of your doctor.
Melatonin should only be used occasionally unless you have otherwise been instructed by a physician, Avena says. Melatonin is considered safe in low doses for short-term use, but there is little data available on its long-term effects and more research is needed to determine overall safety.
If you find you are relying on melatonin in order to fall asleep every night, Avena recommends lowering your dosage slowly. You may experience a few nights of less than great sleep as your body adjusts.
Relaxation techniques like meditation or breathing exercises can help you fall asleep without the help of a melatonin supplement.
“It is more important to have healthy sleep habits and a regular sleep schedule, exercise, and minimal stress, than to rely on any supplement, including melatonin for sleep,” Dimitru says.

What Are Melatonins Side Effects On Kids
Potential, though mild, side effects of melatonin use in children include agitation, headache, dizziness and drowsiness. While it is not known for sure and more research on the long term use of melatonin in children is needed, its important to remember that melatonin is a hormone, and, as such, there is a possibility that it may affect hormonal development, including puberty and menstrual cycles.2
The Bottom Line

When To Talk To Your Doctor About Melatonin
To ensure safe usage, it is always a good idea to consult your doctor before taking any over-the-counter sleep aid, including melatonin. They know your personal medical history and can best advise you on the appropriate melatonin dosage for your needs. They will also know whether melatonin might interact with any other medications you may currently be taking.
Certain health conditions and medications may increase your risk of side effects when taking melatonin. If you take any of the following medications, be sure to talk to your doctor before taking melatonin:
- Pregnant or breastfeeding women
- Shift workers
The research into melatonins potential benefits and use cases is still evolving, and its long-term effects are still unknown. For many people, melatonin offers mild improvements to sleep problems when used on a short-term basis. For others, it may cause side effects or not impact sleep at all.

What Do I Do If Im Experiencing Symptoms Of A Melatonin Overdose
Compared with most other sleep aids, melatonin clears the body quickly, and its effects are short-lasting. If you are experiencing unwanted symptoms after taking melatonin, you can most likely just wait it out as your body processes the drug. However, when in doubt, its always a good idea to seek professional advice. Dont hesitate to contact your doctor or local poison control for guidance on managing worrisome symptoms or determining whether you need medical care.
When To Worry And Seek Medical Assistance
You probably dont need to see a doctor for a minor overdose that causes a mild headache, nausea, or drowsiness. These symptoms may improve once you stop taking the supplement or reduce the amount you take each night.
In the case of a severe overdose or side effect like an abnormally low blood pressure see a doctor right away. You should also get medical help if you feel that the supplement interacts with your prescription medication. For example, you might take your diabetes medication as scheduled to control your blood sugar, yet your blood sugar still remains elevated.
Medical treatment will focus on stabilizing your health. So if too much melatonin causes low blood pressure, your doctor will work to get your blood pressure back to a healthy level.
To avoid complications, talk to your doctor to see whether melatonin is safe for you. If so, get dosing recommendations from your doctor to avoid problems in the future.

Why Is Melatonin So Popular
According to the American Sleep Association, 50-70 million Americans have a sleep disorder, 30% of adults have occasional insomnia, and 35.3% of adults get less than seven hours of sleep in a typical day.
Prescription sleep aids can be addictive or come with serious side effects that result in your eating and driving while youre still asleep. So, people are attracted to melatonin as a natural solution. Unlike other hormones, our brains make melatonin and it naturally occurs in food. Since it shows up in food, melatonin is considered a dietary supplement, which means it doesnt need approval from the Food and Drug Administration and isnt as closely controlled as prescription medicine, according to the National Sleep Foundation. In fact, its the only hormone supplement thats available over the counter.
Since melatonin supplements arent drugs and dont have the scary side effects of other sleep aids, people have been flocking to this all-natural option.
What To Look For
The government doesn’t monitor how companies make food supplements or their quality. So the dose you buy may not be what the label says.
A 2017 study analyzed 31 melatonin supplements. The levels of melatonin ranged from 83% lower to 478% higher than what the product labels said.
Also, in some cases different bottles of the same product varied drastically. That’s why it’s a good idea to buy a brand that has been certified by a consumer lab or the US Pharmacopeial Convention.

What Not To Take With Melatonin
Because melatonin can affect your sleep-wake cycle, avoid taking it with alcohol or caffeine. These can interfere with your circadian rhythm and your natural melatonin production.
Before starting melatonin or any over-the-counter medication or supplement, talk with your doctor. This is especially true if you take other medications.
For example, birth control pills may cause your body to start producing more melatonin, so taking a supplement could push your levels into an unhealthy range.
Taking melatonin with anticoagulant drugs, such as warfarin , could increase your risk of bleeding.
You should also avoid taking melatonin if you take corticosteroids to suppress your immune response for conditions such as rheumatoid arthritis or lupus.
If you think you may have overdosed on melatonin, call Poison Control at 800-222-1222.
You should call 911 and seek emergency help if you have symptoms such as:
- shortness of breath
Work With Not Against Melatonins Sleep
Melatonin levels rise about two hours before bedtime, Buenaver says. Create optimal conditions for it to do its job by keeping the lights low before bed. Stop using your computer, smartphone or tabletthe blue and green light from these devices can neutralize melatonins effects. If you watch television, be sure youre at least six feet away from the screen. Turn off bright overhead lights too. Meanwhile you can help program your body to produce melatonin for sleep at the right time of day by getting exposure to daylight during the morning and afternoon. Take a walk outside or sit beside a sunny window.

Eat Foods Rich In Melatonin
Foods rich in melatonin can also help improve sleep. Fruits and vegetables such as bananas, spinach, tomatoes, and cherries all contain melatonin. Honey, almonds, and oats also encourage melatonin production in the body. If you need a small snack before bed, reaching for one of these foods will help promote rest and relaxation.
Melatonin Overdose: How Much Is Too Much
The number that you read on the medication label may not be what it seems. In fact, the value you read in milligrams or micrograms may not be the amount you’re actually ingesting.
That’s right: the pill that you’re taking could contain five times more of the drug than you think you’re taking. And, that’s exactly what researchers found with over-the-counter melatonin bottles.
This means that you could have been taking more than eight milligrams of melatonin when you only thought that you were taking 1.5 milligrams.
This leads us to a commonly-asked question: is a melatonin overdose possible if you take these pills? And, should you be worried about overdosing from these unregulated over-the-counter medications?

What Is Melatonin
The hormone melatonin comes from a small gland in the brain called the pineal gland, whose primary job is melatonin production. Natural melatonin regulates your bodys circadian rhythms, or the clock that tells your body what time of day or night it is and what its supposed to be doing every day at those times, according to theSociety for Endocrinology.
Normally, melatonin levels increase at night. But many people dont produce these higher levels in the evenings, which means their body clocks arent sending them the right signals. The reasons why are varied some people struggle to sleep well when they have certain medical or mental health conditions, like anxiety or depression, while others can trace their sleeplessness to situational or environmental causes.
The natural release of melatonin can be altered by cell phone screens, TVs, and bright lights throughout the house, says Anjali Kohli, MD, internist at Houston Methodist Primary Care. Other common causes include disturbances in the sleep wake cycle caused by jet-lag or shift work.
Not making enough melatonin can lead to the occasional sleepless night, but it can also cause primary sleep disorders like insomnia, sleep apnea, circadian rhythm sleep disorder, and restless leg syndrome. When sleeplessness becomes persistent, many people choose to take a melatonin supplement to boost their bodys natural levels of melatonin.
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.
of melatonin in children show that it is safe, including in children with autism.

Is Melatonin Safe For Teens And More Teen Sleep Questions
Teenagers are the most sleep-deprived segment of the U.S. population. Many teens are chronically tired, yet report difficulty falling asleep. Is it safe for teenagers to take supplements such as melatonin? What can teenagers do to fall asleep more quickly and get more sleep? Your Teen asked our questions about teen sleep to James Maas, Ph.D., best-selling author of Power Sleep, Sleep for Success, and Sleep to Win! Professor Maas is a leading authority and international consultant on sleep and performance.
Q: Why do many teenagers stay up late and have problems falling asleep? Can we blame it all on phones?
Maas: The problem is not just phones. The adolescent brain is chronologically set to go to sleep at 2 a.m. and to wake at 11 a.m. Melatonin, a hormone produced by the brain, plays a role in sleep when we turn off the lights. However, the growth hormone that the body produces around midnightwhich it does in significant amounts from puberty to about age 24suppresses the production of melatonin. As a result, a teenager would best be prepared to sleep around 2:00 a.m. This is called Chronic Delayed Phase Syndrome, and every adolescent has it. This delay in falling asleep causes difficulty in waking up and being alert much before 11 a.m. So much for early school start times. We have the bodies of our teens in the classroom by 7:30 or 8:00 a.m. but their brains are back on their pillows.
