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.
Alternatives To Taking Melatonin
If you have trouble sleeping, it is always wise to see a doctor. A doctor can assess your symptoms and determine if a medical condition may be an underlying cause. If that turns out to be the case, your doctor can then identify treatment options that may also allow you to sleep soundly.
If you want a more restful sleep without melatonin supplements, start by establishing a sleep/wake routine. By following the same schedule nightly, you can create a pattern that your body gets used to, increasing the odds that youll be sleepy at the right time.
Avoid caffeine, alcohol, exercise and digital devices at least a few hours before bed. All of those things can disrupt your natural melatonin production, so forgoing them as the evening approaches can help. Anxiety can also hamper sleep. Finding natural ways to relieve stress can help.
For some, herbal tea can promote better sleep. Some find consuming them relaxing, and that general sense of calm can make a difference.
How Much Melatonin Should I Take How To Find Your Optimal Dose

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 Is The Right Dosage Of Melatonin: How Much Is Too Much
Knowing how much melatonin to take is tricky, especially since some brands may recommend a dosage thats more than your body actually needs.
As you shop around, youll find that some melatonin supplements contain as much as 5 to 10 milligrams per serving.
Generally speaking, most people produce enough melatonin to sleep well. If you need a little extra to reset your sleep cycle, you probably dont need more than 3 mg. Some people sleep better with as little as 0.3 to 0.5 mg.
Melatonin needs vary from person to person. Since melatonin can have many effects on the body, like all drugs, it should be taken at the lowest dose possible, warns Dr. Jacobowitz.
With that being said, start with a low amount. If you still have problems sleeping, gradually step up your dose until you find an amount that improves sleep without causing side effects.
Less is more with melatonin to avoid sleep inertia. This is a common problem with some sleeping pills. Some people complain of a hungover or groggy feeling in the mornings due to remnants of the sleep aid remaining in their bloodstream.
This effect doesnt typically occur with melatonin, but it can happen if you take too much the night before.
Melatonin is also safe for children. And like adults, some children dont need a lot of the supplement to sleep better.
Again, start your child at a lower dose, and then gradually increase the amount of melatonin as needed. Talk to your doctor for advice on appropriate dosages.

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.
Does Melatonin Interact With Other Medications
Melatonin may interact with other medications that are also metabolized by the same liver enzymes, leading to higher plasma melatonin concentrations. It is recommended to consult with your healthcare provider if you are currently on a prescription medication and plan on using melatonin supplements.
âItâs best to start with a low dose of melatonin. If you give your body more than it needs, itâs possible to have the opposite effectâ¦â

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.
My Child Is Already On Melatonin Do I Need To Freak Out
I dont think so, as there is little concrete evidence of significant harm. However, if you started melatonin on your own I beg you to discuss it with your childs physician to see if it is really necessary. If your child has been using it long-term and sleeping well, you can consider slowly reducing the dose and seeing if it is still really necessary. Try to use it as needed as opposed to nightly. Also, I would take a hard look at sleep hygiene and ensure that you are ensuring good bedtime processes such as a high quality bedtime routine and avoidance of screen time for at least an hour prior to bedtime. I would try to reduce the dose, and potentially only use it as needed as opposed to nightly.

My Doctor And I Have Talked About It What Should We Consider Regarding How And When To Give Melatonin
Melatonin can be a tricky medication to dose. Effects change depending on when you give it compared to your childs usual sleep schedule. Thus, a small dose a few hours before bedtime can have more of an effect than a large dose given at bedtime. In some situations dosing may the opposite effect. This is a special case and should be addressed with your physician. A couple of rules of thumb.
- Timing: For shifting sleep schedules earlier 36 hours before current sleep onset is best. For the sleep onset effects, 30 minutes before bedtime is recommended. Remember, not every child gets sleepy with melatonin.
- Dosing: In general, I would start at a low dose and increase slowly. Recognize that melatonin, unlike other medications, is a hormone, and that lower doses are sometimes more effective than higher ones, especially if the benefit of it reduces with time.
- Good Sleep Hygiene is Critical: Melatonin is not a substitute for good sleep hygiene practices and should only be used in concert with a high quality bedtime, limitation on light exposure, and an appropriate sleep schedule.
- When possible, purchasing a USP Verified preparation may indicate that the product is manufactured to the requirements of the U.S. Pharmacopeial Convention, which could mean that the quality controllers are tighter.

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.

In a meta-analysis of 16 studies, melatonin dosages between 0.1 milligram and 50 milligrams per kilogram were administered to older adults aged 55 to 77 years old. In all of the studies, the melatonin levels remained higher among the older adults when compared to younger adults and stayed higher for a longer period of time leading to increased daytime drowsiness.
