What Are The Health Benefits Of Taking Melatonin
Melatonin supplements may help with certain conditions, such as jet lag, delayed sleep-wake phase disorder, some sleep disorders in children, and anxiety before and after surgery.
Jet lag affects people when they travel by air across multiple time zones. With jet lag, you may not feel well overall and you may have disturbed sleep, daytime tiredness, impaired functioning, and digestive problems.
Research suggests that melatonin supplements may help with jet lag. This is based on medium-sized reviews from 2010 and 2014.
- Four studies that included a total of 142 travelers showed that melatonin may be better than a placebo in reducing overall symptoms of jet lag after eastward flights. Another study of 234 travelers on eastward flights looked at only sleep quality and found low-quality evidence that melatonin may be better than placebo for improving sleep quality.
- Two studies that included a total of 90 travelers showed that melatonin may be better than a placebo in reducing symptoms of jet lag after westward flights.
Delayed sleep-wake phase disorder
People with DSWPD have trouble falling asleep at the usual times and waking up in the morning. They typically have difficulty getting to sleep before 2 to 6 a.m. and would prefer to wake up between 10 a.m. and 1 p.m.
Some sleep disorders in children
Because of these uncertainties, itâs best to work with a health care provider if youâre considering giving a child melatonin for sleep problems.
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.
How Much Melatonin Should I Take
Its best to start with the lowest recommended dosage of melatonin for your age. From there, you can gradually increase your dosage until you find a dose that helps you fall asleep without causing any side effects. A safe starting dose for adults is between 0.5 milligram and 5 milligrams of melatonin. Older adults may find lower doses, starting with 0.1 milligram, to be safe and effective. Children should not take melatonin unless recommended by a doctor.
Over-the-counter melatonin may come in standard amounts like 1 milligram, 3 milligrams, or 5 milligrams. You can use a pill-cutter to cut the tablets in half or quarters to create a smaller starting dose.

Is Melatonin Approved By The Fda
Melatonin is not approved by the FDA for any use. It falls under the FDAs Dietary Health and Education Act as a dietary supplement. Dietary supplements may include vitamins, minerals, amino acids, and herbs or botanicals, plus other substances used to supplement the diet. As with other dietary supplements, melatonin isn’t approved by the Food and Drug Administration for safety or effectiveness.
Manufacturers must notify FDA about new ingredients prior to marketing. After the supplement is on the market, the FDA will monitor adverse event/s that are reported to them by the manufacturer, consumers or health care professionals. If a manufacturer makes an unproven health claim or if the supplement is found to be unsafe the FDA can remove the OTC from the market.
Avoid buying dietary supplements from the Internet and from online pharmacies whose authenticity you cannot verify. It is important to remember that an OTC label that says natural supplement does not always mean its safe for consumption. Formulations that are United States Pharmacopeial Convention Verified can be considered most reliable in this regard the label USP is found on the outside of the bottle. For example, all Nature Made products are verified by the USP. The safest way to purchase drugs online is through pharmacies accredited by the Verification of Internet Pharmacy Practice Sites programs.
Avoid Or Use Cautiously With Certain Drugs Hypnotics And Alcohol
Fluvoxamine increases melatonin concentrations by inhibiting cytochrome P450 1A2 and 2C19 enzyme metabolism: avoid this combination.2 Consider melatonin carefully in people receiving cimetidine , 5- or 8-methoxypsoralen or oestrogen therapy , as these drugs can also increase melatonin concentrations.2 Interactions with other CYP1A2 inhibitors and CYP1A2 inducers are theoretically possible.2
Do not use melatonin with benzodiazepines and related hypnotic drugs: this increases the risk of cognitive and psychomotor adverse effects, and there are no efficacy data for this combination.2,5
Avoid concomitant use with alcohol as this may affect the prolonged-release properties of melatonin.2

Some people taking melatonin to help with sleep may take it for up to 13 weeks to make sure a normal sleep pattern is established.
Some people may need to take melatonin for longer .

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.
What Medications And Substances Does Melatonin Interact With
Melatonin may interact with several different types of medications, including:
- Blood-thinning medications. Taking melatonin with blood-thinning medication may increase your risk for bleeding.
- Epilepsy medications . Melatonin may make these medications less effective.
- Immunosuppressants. Melatonin can potentially interfere with immunosuppressive drugs.
- Diabetes medications. Melatonin use can affect blood sugar levels.
- Blood pressure medications. Blood pressure may get worse when melatonin is taken with these medications.
- Contraceptive drugs.Birth control pills may increase the risk of side effects from melatonin.
Because melatonin supplements can make you tired and drowsy, avoid mixing them with:
- other sleep aids
How To Supplement With Melatonin
To aid sleep, the standard dosage ranges from 1 to 10 milligrams per day. However, the optimal dose has not been formally established .
Since not all melatonin supplements are the same, make sure to follow the instructions on the label.
Also, keep in mind that the quality of over-the-counter supplements is not monitored by health authorities. Try to choose brands that are reputable and certified by a third party, such as Informed Choice and NSF International.
Many experts do not recommend their use in children and adolescents until more evidence confirms its safety in these groups .
Since melatonin is transferred into breast milk, breastfeeding mothers should keep in mind that it might cause excessive daytime sleepiness in nursing infants .
The common dosage of melatonin ranges from 110 mg per day, but make sure to follow the instructions on the label. Parents should not give it to their children without first consulting their medical provider.
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

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.
Is Melatonin Habit Forming
Melatonin is not considered to be habit-forming or cause dependencies. It is generally safe for short-term use. If you find yourself using it every day for longer than 2 weeks, its important to talk to your doctor about your symptoms to rule out underlying conditions causing problems with your sleep.

Does Melatonin Have Any Side Effects
A few studies have investigated the safety of melatonin, but none have revealed any serious side effects. It also doesnt seem to cause any dependence or withdrawal symptoms .
Nonetheless, some medical practitioners are concerned that it may reduce the natural production of melatonin in the body, but short-term studies suggest no such effects .
Several studies have reported general symptoms, including dizziness, headache, nausea or agitation. However, these were equally common in the treatment and placebo groups and couldnt be attributed to melatonin .
Melatonin supplements are generally considered safe in the short-term, even when taken in very high doses. However, more research on its long-term safety is needed, especially in children .
A few mild side effects and drug interactions are discussed in the chapters below.
Summary Melatonin supplements are considered safe, and no studies have revealed any serious side effects to date. Yet, more research is needed to evaluate its long-term effects.

Can You Overdose On Melatonin How To Determine The Right Dosage For You
Melatonin is natural, but taking too much of the supplement may lead to adverse side effects. Heres how to recognize signs of a potential overdose.
Tossing and turning night after night can take a toll on your mental and physical health. This can make you feel sluggish, irritable, and achy throughout the day. So naturally you might seek a sleep aid for better rest.
Melatonin is a neurohormone that controls our sleep-wake cycle, and many formulations and dosages are available over the counter, explains Ofer Jacobowitz, MD, PhD, an otolaryngologist and sleep expert based in New York City. It can be useful when you are trying to advance your bedtime, especially when combined with reducing light exposure two hours before bedtime.
Melatonin is naturally produced by the pineal gland and gradually released into your bloodstream as you prepare for sleep. But if your body doesnt produce enough of this hormone, you may have problems falling asleep or staying asleep.

Side Effects Of Melatonin: What Are The Risks
Melatonin is a hormone and dietary supplement commonly used as a sleep aid.
Although it has an outstanding safety profile, melatonins growing popularity has raised some concerns.
These concerns are mainly due to a lack of research on its long-term effects, as well as its wide-ranging effects as a hormone.
This article reviews the potential side effects of melatonin supplements.
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.

Melatonin Supplements Are Hormone Therapy
Are you taking melatonin? Then you are using hormone therapy. Hormone therapy is a very complicated topic rife with detrimental health consequences when used carelessly. Often, hormone therapy is the easy answer to hormone imbalance and so the layperson, under the guidance of a practitioner or not, will reach for this answer. One common example of hormone therapy is progesterone cream. Melatonin is another.
The popularity of melatonin greatly worries me because hormone therapy should be approached with due caution, wisdom and knowledge. The practitioners whom I most respect use hormone therapy with the most extreme reservation, always preferring to use diet/lifestyle/supplement changes before using hormone therapy only when necessary as a last resort. Why? More often than not, including the case of melatonin, hormone therapy can do more harm than good.
This is the analogy I use when explaining the potential consequences of hormone therapy:
Most of the hormones in the body are governed by negative feedback, which works like your household thermostat. Say you set your thermostat to 72 degrees and the room temperature is 69 degrees. The heater kicks in to warm the room up. When the temperature reaches 72 degrees, the heat shuts off until the temperature drops again.
Administering hormones can actually shut off our bodys hormonal negative feedback loop. Its like heating a room by a space heater and the furnace shuts off because it isnt needed.
