The above intake amounts have been studied scientifically, but always check with your doctor first before supplementing your melatonin to find the safest intake for your individual needs.6
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.
Nobody Knows What Dosages To Take
Melatonin
Claims, Benefits: Promotes sleep, counters jet lag, improves sex life, slows aging, etc.
Bottom Line: This human hormone may help promote sleep, but the evidence is still not definite. The other claims are unproven. No serious side effects have been reported, but long-term effects are unknown. Hormones are powerful substances and can produce unexpected results, so we don’t recommend melatonin.

Melatonin: Questions, Facts, Mysteries
Look on any website selling supplements or in any health-food catalogue, and you’ll find melatonin recommended for insomnia, jet lag, arthritis, stress, alcoholism, migraine, and the signs and symptoms of aging and menopauseâalong with assertions that it staves off heart disease and cancer. Some people recommend “melatonin replacement therapy” for all postmenopausal women. But now that scientific research is catching up with melatonin mania, you may want to proceed with caution.
Melatonin is a human hormone produced deep in the brain by the pineal gland, dubbed “the seat of the soul” by philosophers in ages past. Discovered about 40 years ago, melatonin has been called the “darkness” hormone. Production rises at night, falls by day, and affects our internal body clock and sleep cycles. Melatonin has been assumed, logically enough, to have some use as a sleeping pill. Here are some questions, facts, and mysteries.
Does melatonin production decline with age?

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.
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.

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.
Risks Of Taking Other Drugs With Melatonin
Taking melatonin in any amount can be dangerous if you are also taking certain other medications. Unfortunately, this includes medications that can also make it difficult to sleep. People who use blood pressure drugs, for example, may have a lower amount of naturally occurring melatonin. However, taking melatonin can cause blood pressure spikes, which could be incredibly dangerous.
On the other end of the spectrum, birth control pills can lead to elevated melatonin production. Taking a supplement could push your concentration into dangerous territory. Individuals using anticoagulants may see an increased risk of bleeding if they also use melatonin. Those on corticosteroids should also avoid the supplement. It also isnt wise to take melatonin in conjunction with caffeine or alcohol. Both of those substances impact circadian rhythms and natural melatonin production.

Moving New Comment To Bottom Of Page
No one would have seen this comment up there in between comments from 2013:
- I just read the article and it said basically that melatonin was the strongest antioxidant by saying it was twice stronger than vitamin E which is considered the most effective antioxidant . Later it also says it’s more effective against ionizing radiation than the commonly used treatments, and that this is due to fighting free radicals. Also there is absolutely nothing at all linked with Melatonin in this article that would read as other than a positive effect. So… Maybe it was more perfect before, but right now the claims sound inflated to me. Dlamblin 05:19, 21 July 2015

Role Of Melatonin In The Endocrine System
There seems little doubt that melatonin has an influence on different components of the endocrine system, but the literature provides viewpoints that are difficult to reconcile, and difficult to summarise in a short article. The edit replacing one long-standing unsourced statement that melatonin was the “master hormone” with another that it was not was an interesting anonymous viewpoint, but more information on the facts are needed, since melatonin is known to influence HGH, FSH, LH, the thymus gland etc. Elroch 01:30, 5 May 2006

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
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.
Questionable Reliability Of Reference
A reference has recently been added to an article “Harms from a pseudo-cure-all” by the late Dr. Victor Herbert. The sensational statements in his article set off alarm bells, and a search immediately uncovered material like this response by the author of a article relating to a study on Vitamin C from which Dr. Herbert was stated to have made to be a large number of false inferences. This alone makes me feel very uncomfortable relying on Dr. Herbert as a secondary source. It seems essential that Dr. Herbert’s statements be replaced by ones referring to primary or balanced sources.
I am not sure how much can be inferred for humans from the effects of injecting large doses of melatonin into minah birds. As I understand it, the many studies relating to mammals whose genetic makeup is much closer to that of humans are generally considered to carry more weight as evidence for what might happen in humans. Also the current last sentence does not make sense: it is unquestionable that melatonin has several biochemical roles.Elroch 23:35, 17 February 2006
- Elroch would do well to cite a better rebuttal to the Herbert’s citation than to cite an instance in which James E. Enstrom a PhD whose research funded by the tobacco industry was widely discreditedrebutted Victor Herbert MD JD on an unrelated matter pertaining to Vitamin C and not to melatonin.

Chronic Sleep Onset Insomnia And Melatonin:
Problems with falling asleep are common in children, just like in adults. In children with chronic difficulty falling asleep within 30 minutes of an age-appropriate bedtime. Use of melatonin results in less difficulty with falling asleep, earlier time of sleep onset, and more sleep at night. The initial studies used pretty high doses, but later studies comparing different doses showed that dose didnt matter, and that the lowest dose studied was as effective as the highest. This is likely due to the fact that ALL these doses were well above the amount produced naturally in the children. Timing between 67 PM was more effective than later doses. The authors point out that a midafternoon dose would have the best effect but that afternoon dosing would have the unpleasant side effective of making children sleepy in the afternoon. .
Role Of Melatonin In Tumor
There are several mechanisms by which tumors evade an immune response including activation of regulatory cells, deformed antigen presentation, immune suppression, and immune deviation . Melatonin has an impact on immune cells by enhancing their viability, improving cell metabolism in the tumor microenvironment, and modulating cytokines release . It was reported that melatonin can stimulate T cell and natural killer production in in vivo study . Liu et al. demonstrated the reduction effect of melatonin on regulatory T cells and Forkhead box p3 in gastric cancer cells . According to Wongsena et al., melatonin has an immunomodulatory effect in hamsters treated with a chemical carcinogen. The results showed that a dose of 50 mg/kg melatonin was able to reduce eosinophils, Th17 cells, and Foxp3 expression, as well as increase CD4+ and TNF- accumulation . Other studies exhibited stimulation of Th1 in tumor-bearing mice treated with melatonin .

What Are Signs Of A Melatonin Overdose
If you deal with insomnia, you might do anything for relief. Melatonin is a popular go-to sleep aid because its natural and has a low risk of unwanted side effects.
But while side effects are less common with melatonin compared with other sleep aids, you may experience a few if you overdose and take too much.
There dont appear to be any reports of people dying from overuse of melatonin. But while overuse might not cause death, it can cause a few of the below symptoms:
- Headache
Theres also the threat of rebound insomnia when theres too much of the hormone in your system. Melatonin may stop working after a while, and your sleep problems could even worsen.
What Medication Can Interact With Melatonin
Its important to know how other medicines may interact with melatonin. As a general rule of thumb, consult your doctor before taking any new herbs or supplements.
Melatonin can reduce the effectiveness of some prescription drugs, triggering possibly serious complications.
For example, you shouldnt combine an anticoagulant or blood thinner medication with melatonin. Melatonin can increase the risk of bleeding.
Melatonin may also increase blood pressure in people who take medication to control their hypertension.
Other drugs that may interact with melatonin include:
- Anticonvulsants
- Selective serotonin reuptake inhibitors
Also dont take melatonin if youve been diagnosed with an autoimmune disease, like lupus.
Autoimmune diseases are the result of an overactive immune system, and inflammation is a classic symptom on these diseases. Melatonin can stimulate immune system activity, increasing inflammation and exacerbating an existing disease.

How Long Does It Take For Melatonin To Work
Melatonin supplements typically begin to kick in between 20 minutes and two hours after ingestion, which is why Buenaver suggests taking one to three milligrams two hours before bedtime.
Additionally, natural melatonin levels rise around two hours before bed, so having a consistent bedtime routine can help signal to your body that its time to ramp up melatonin production.
Melatonin can affect everyone differently, meaning theres no single right answer to how long melatonin lasts. You may need to do some trial and error to figure out when to take melatonin before bed and how much to take so you can stay asleep.
General Melatonin Side Effects & Warnings
Its important to talk to your doctor before beginning any new dietary supplement, especially if you are on a prescription medication, have a health condition, or are pregnant or breastfeeding.
That said, melatonin still ranks as likely safe when taken for up to 2 years if used properly and possibly safe for long term use.12 Some people have complained of headache, dizziness, stomach cramps, short term feelings of depression and irritability.12
- Pregnancy & Breastfeedingwomen who are pregnant or breastfeeding are not advised to use melatonin supplements because not enough is known about potential effects.1,3 Melatonin supplements may also interfere with ovulation, making it more difficult to get pregnant.12
- Blood Sugar & Blood Pressurepeople suffering from diabetes or high blood pressure should consult their doctor before taking supplemental melatonin as it can increase blood sugar in diabetics and raise blood pressure in people who take certain blood pressure medications.12
- Depressionmelatonin may worsen symptoms of depression and cause short-term feelings of depression.12
The best advice is to start low and go slow. In other words, dont immediately go for the highest dose you can find. Ultimately, the low .3-1 mg pill might be just what your tired body needs.
