Does Melatonin Have Side Effects Can You Overdose On Melatonin
Melatonin has a reputation for being safe, and for the most part, thats truethough there are some medications that can interact with melatonin.10 But its important to know that the right amount of melatonin for one person may be too much for another, and the side effects of a taking too much melatonin will also vary from person to person.10

What Is Melatonin Used For
People use melatonin supplements to adjust the bodys internal clock. It is used for jet lag, for adjusting sleep-wake cycles in people whose daily work schedule changes , and for helping blind people establish a day and night cycle. Melatonin is naturally-made, has a low side-effect profile, and there is substantial scientific evidence showing its efficacy.
Melatonin has also been studied for the treatment of cancer, immune disorders, cardiovascular diseases, depression, seasonal affective disorder, and sexual dysfunction. The results of most of these studies remain inconclusive. However, it has been shown to clearly ameliorate seasonal affective disorder and circadian misalignment, in studies by other researchers.

How Much Melatonin Can Children Take
Few studies look at the use of melatonin in healthy children, including research into appropriate dose levels, so it’s challenging to come up with an exact amount. If you’re concerned about your child or infant’s sleep habits, it’s best to speak with your pediatrician before attempting any at-home dosing.
Some kids, such as children with immune disorders or those taking immunosuppressants, should not take melatonin at all. While melatonin is generally well-tolerated in adults, further studies are needed to confirm its safety and efficacy in children.
Anatomical and physiological differences give rise to differences in the bodily absorption, distribution, metabolism, and excretion of drugs in children compared with adults. Many medicines, including melatonin, have only been tested for safety and efficacy in adults.

Are There Any People Who Should Avoid Taking Melatonin
Theres limited research into the safety of using melatonin supplements during pregnancy. Also, while melatonin is a normal component of breast milk, theres little research into the effects of taking melatonin supplements while breastfeeding.
Because of this, its best to avoid taking melatonin if youre:
- pregnant
Its a good idea to schedule an appointment with your doctor or healthcare provider if you notice that you:
- frequently have trouble falling asleep or staying asleep at night
- often feel drowsy or tired during the day
- have trouble performing your daily activities
Your doctor will work with you to discuss your sleep routine and lifestyle habits. They may also ask you to keep a sleep diary to track the amount of sleep youre getting over a period of time.
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.
What Is The Correct Melatonin Dosage For Me
The recommended dose of melatonin is the lowest dose that can help your sleep quantity and quality without causing side effects. While the right dose varies from one person to another, between 0.5 milligrams and 5 milligrams once daily is the typical starting dose for adults. Research indicates that taking doses of 10 milligrams or higher may cause side effects. The maximum recommended dose of melatonin is 10 milligrams.
Several factors, such as age, body weight, and sensitivity to melatonin may affect the recommended dosage. The dose also depends on the type and severity of the sleep problem. Certain drugs may also affect the way melatonin is metabolized. Speak to your physician if you are taking other medications before starting melatonin.
When using melatonin for the first time, begin at a low dose and adjust in increments of 1 milligram, depending on response. Generally, the optimum time to take melatonin is one to two hours before bedtime. There’s some evidence of tolerance with melatonin use, so it’s not recommended to increase the dose over time after reaching the lowest effective dose.

Some Additional Changes Made
I addressed 3 things: misleading statements about regulatory status in the introduction, and inflated claims made around this dietary supplement as an antioxidant and in respect of cancer. It is not just that large sections of this article are a biased selection of primary sources claiming benefit: they’re often animal studies or pure conjecture, not even necessarily primary studies. A lot of this could really just be pruned, and the article would be immeasurably better as a source of information for it. Hildabast 01:32, 6 June 2013

When Should You Take Melatonin
Timing is important with melatonin. Remember, your body should naturally produce more melatonin when it starts to get dark outside, so if you take supplemental melatonin too early in the eveningbefore the sun starts to set or before you are actually ready to fall asleep for the nightyou risk throwing off the natural cycle your body is trying to maintain. Dont fight that natural flow.
Melatonin can be very beneficial when your regular sleep schedule gets disrupted. For example, if youve flown across several time zones and have jetlag, or if its a big week at work that requires successive late nights. In situations like those, melatonin supplements can help you get back into your natural rhythm.
Theres another timing issue to be aware of, too. As you age, your body may naturally produce less and less melatonin.3 If you are over 60 and struggle with falling sleep or are waking up during the night, low melatonin production may be part of the problem.

Does Melatonin Work For Shift Workers
Shift work that involves night shifts may cause people to feel sleepy at work and make it difficult to sleep during the daytime after a shift ends.
According to two 2014 research reviews, studies on whether melatonin supplements help shift workers were generally small or inconclusive.
- The first review looked at 7 studies that included a total of 263 participants. The results suggested that people taking melatonin may sleep about 24 minutes longer during the daytime, but other aspects of sleep, such as time needed to fall asleep, may not change. The evidence, however, was considered to be of low quality.
- The other review looked at 8 studies , with a total of 300 participants, to see whether melatonin helped promote sleep in shift workers. Six of the studies were high quality, and they had inconclusive results. The review did not make any recommendations for melatonin use in shift workers.
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.

Can Melatonin Help With Insomnia
People with insomnia have trouble falling asleep, staying asleep, or both. When symptoms last a month or longer, itâs called chronic insomnia.
According to practice guidelines from the American Academy of Sleep Medicine and the American College of Physicians , thereâs not enough strong evidence on the effectiveness or safety of melatonin supplementation for chronic insomnia to recommend its use. The American College of Physicians guidelines strongly recommend the use of cognitive behavioral therapy for insomnia as an initial treatment for insomnia.
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.

Can I Take Melatonin Every Night
Melatonin is generally safe for short-term use, but further research is required to assess the long-term safety of melatonin use. In the United States, melatonin is considered a dietary supplement, which are regulated less strictly by the Food and Drug Administration than prescriptions and over-the-counter medications. Federal law doesn’t require dietary supplements to be proven safe to FDA’s standards before they are sold.
Furthermore, some melatonin supplements may not contain what is listed on the product label. Researchers tested 31 commercial supplements and found that most products contained far more or far less melatonin than what was listed on the label. Some supplements contained serotonin, a hormone that wasn’t recognized on the product label.
Although melatonin is generally regarded as well-tolerated, it may not be ideal for long-term use, unless specifically instructed by your doctor. Supplemental melatonin shifts the phase of the human circadian clock, and thus warrants caution. The principle of treatment of sleep disorders is first to find the cause of the sleep disturbance, and then treat the conditions causing the distress.
Treatment options for primary sleep disorders, or sleep disorders that aren’t caused by another medical or psychological condition, often include behavioral therapies. Sleep hygiene, sleep restriction, stimulus control, relaxation training, and cognitive therapy are examples of such therapies.
Does Not Have To Be Prescribed
Actually in most Commonwealth countries Melatonin must be prescribed by a doctor. Article should be edited to reflect a global viewpoint.
- in Poland it is possible to buy melatonine without prescription, it costs about â¬5 for 30 tbl. 5 mg. Anyone can buy it by internet too: – see ?! – and because Poland is an EU member so i conclude that similar regulations is in many other EU-countries also. pwjbbb 01:09, 13 June 2007
- In Norway, which is not an EU country, melatonin is available only on the 2nd most restrictive type of prescription. To get melatonin, one has to have a specialist fill out an application, annually, with the patient’s name and diagnosis on it. It takes a few days for the application to go through and for the pharmacy to order the melatonin. Over-the-counter it is NOT. Hordaland 14:09, 2 November 2007
Melatonin is OTC in Estonia too. One can choose between 2mg and 3mg pills. Kristjan.
- That’s interesting. It’s strange that the rules vary so widely from country to country. I don’t suppose anyone has the complete list. The stuff is a hormone, so I’d think there should be some controll….

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.
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.
