Factors Influencing The Melatonin Levels In Your Body:
Who Should Take Melatonin
*For occasional insomnia and sleeplessness: Short term help for certain insomnia such as delayed sleep disorder or other sleep disorders affecting circadian rhythm. Some report that Melatonin helps reduce the time it takes for them to fall asleep.
*Children with neurodevelopmental disorders
Jet Lag And Shift Work
Melatonin is known to reduce jet lag, especially in eastward travel. If the time it is taken is not correct, however, it can instead delay adaptation.
Melatonin appears to have limited use against the sleep problems of people who work shift work. Tentative evidence suggests that it increases the length of time people are able to sleep.

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….

What Is Melatonin & How Does It Work
Melatonin is a natural hormone produced in your brain. It is responsible for helping maintain your bodys circadian rhythm, which is your natural, 24-hour sleep and wake cycle.3 Your body should naturally produce and release more melatonin in the evening and at night, with levels falling in the morning.4 The production of melatonin is your brains way of telling your body that its time to sleep.
Its a pretty clever little hormoneit knows when its dark or light out. Darkness causes your body to produce more melatonin, which then provides a sleep signal and helps you fall asleep. Exposure to light, on the other hand, decreases melatonin production and signals your body that its time to wake up and be alert.
Research suggests that some people who struggle with falling asleep or staying asleep may not produce enough natural melatonin.5 Thus, melatonin supplements are often used to help regulate their natural sleep and wake cycles. But melatonin supplements should only be used at the appropriate time of day, and only in recommended amounts.
What Is The Optimal Melatonin Dosage
This is a 7-minute read
When taking melatonin, it is important to take an appropriate dosage at the right time when needed for safe and effective use. It is a common misconception that taking more melatonin will result in a deeper and more restful sleep. But the reality is, too much melatonin can lead to nighttime restlessness and daytime grogginess.
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.

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.
How Do Melatonin Supplements Work
Basically, melatonin supplements add more melatonin to the mix. Our bodies produce melatonin naturally to help us start to fall asleep, says Dr. Nicole Avena, Ph.D., assistant professor of neuroscience at Mount Sinai School of Medicine. Taking the supplement can be helpful for people who have trouble settling down naturally to sleep. By increasing the amount of melatonin, you give your body even more signals to go to bed, which may help you fall asleep faster and get higher quality sleep through the night.
Melatonin regulates the natural sleep-wake cycle, adds Dr. Cinthya Pena Orbeaof Cleveland Clinics Sleep Disorders Center. Levels start to increase in the evening by reaching the highest levels before bedtime.
People who work night shifts, have jet lag, or experience delayed sleep phase disorder also turn to melatonin for help. Since the hormone helps regulate the circadian rhythm, melatonin may help in reestablishing the regular day/night sleep schedule.
Melatonin dosage can vary, as every person reacts differently to the hormone. Since some people are more sensitive than others to the effects of melatonin, it is best to start off low and increase your dose as needed, Dr. Avena says. Doses of 0.2-5 mg are considered safe.

Is Melatonin Safe For Kids
While plenty of studies shows that melatonin is safe for adults to take on a short-term basis, the safety of long-term use isnt quite clear. And not much research has been done on whether its safe for children to take. However, recently, there has been some promising research showing that short-term use of melatonin is effective and well-tolerated in treating difficulty falling asleep in children and adolescents.3 Other research shows that melatonin may be especially helpful for children with conditions that can impact their ability to fall asleep, such as attention deficit hyperactivity disorder and autism.4 Melatonins use in these circumstances should be discussed and carefully monitored by your childs pediatrician.4
The American Academy of Pediatrics recommends that melatonin should only be used after talking with your childs pediatrician and after using already established healthy sleep habits and routines that dont include medication.4

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.
“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.

Is Melatonin Safe For Children
Children who sleep well may have better academic performance and fewer weight concerns. They also may be less likely to get injured playing sports and have healthier immune systems. In fact, some experts believe that many children who have trouble focusing simply have poor sleep habits and arent rested well enough to pay attention as they should in the classroom.7
Since sleep is so important, is it safe to give your child melatonin to help them get the rest they need? Unfortunately, there hasnt been enough research on melatonin use in children to be sure. Melatonin is a hormone, so it must be used carefully, but some research suggests that a very low dose of liquid melatonin used on a limited basis may help children fall asleep.8
What Are The Symptoms Of A Melatonin Overdose
It is important to note that just because a supplement is unlikely to be lethal, that does not mean that unwanted or troubling side effects cannot occur. Concerning symptoms have been reported with higher doses of melatonin.
Possible symptoms of too much melatonin include:
Because melatonin can affect the cardiovascular, dermatologic, and central nervous systems, those with other conditions may be vulnerable to additional risks. Evidence suggests that melatonin supplementation may induce depression, particularly in people predisposed to or currently experiencing this malady. Research on this topic, however, is conflicting, since some studies have demonstrated the potential for melatonin to treat depression.
People taking blood thinners, like warfarin, and benzodiazepines should be careful, as there is a possibility for interaction. Those with epilepsy should also exercise caution, as melatonin has been associated with increased seizures.
Research suggests that elderly people, who have lower natural levels of melatonin, may be more sensitive to the effects of melatonin supplements. Therefore, older people are encouraged to check with their doctor before taking melatonin and start with the lowest possible dose.

Melatonin And Kids With Adhd
Attention deficit hyperactivity is commonly associated with sleep problems, just as sleep problems can cause attentional issues. As many as 70% of children with ADHD may have sleep problems. Sleep problems include difficulty falling asleep, abnormalities in sleep architecture , and daytime sleepiness. Trials of melatonin showed that it helped children with ADHD to fall asleep more quickly, although there was no evidence of improvement in attentional symptoms during the day. Side effects reported included problems with waking up at night and daytime sleepiness in some children. There is a nice review article here.
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
