How Long Does Melatonin Work

How Long Will Melatonin Make You Sleep

What is melatonin and how does it work?

With melatonin, you cant really say that taking the medicine will guarantee you will be able to sleep for a particular length of time. It is not a conventional sleeping pill.

Rather, melatonin will help to regulate your own internal clock and so, it will help you maintain your normal sleep schedule. That means that youll wake up the next day as normal, but this time after a good night of sleep.

How Long Does It Take For Melatonin To Wear Off

Melatonin takes between four to eight hours to wear off, but the amount of melatonin you take can cause this number to vary significantly. Generally, Buenaver suggests taking the lowest dose possible and advises starting at around one to three milligrams.

At a lower dosage, the melatonin will wear off quicker, and youll be less likely to experience any side effects.

How Much Melatonin Should I Take

Most studies on melatonin use doses ranging from 1 to 5mg.

High doses of melatonin are not typically recommended, and many professionals suggest starting at the lower dosage of 1 mg and gradually increasing if needed.

Many people find sleep success with a 3mg dose.

When using melatonin for jet lag, the dose with the best-reported effectiveness is 5mg.

If you find yourself waking up groggy or very sleepy the next day, your dose is likely too high, and you should reduce it the next time.

Also, taking too much melatonin can have the opposite effect, making it harder to sleep because your normal circadian rhythms are disrupted.

Consider Melatonin Sleep Help For Occasional Insomnia

Even sound sleepers have trouble falling asleep or staying asleep once in a while, Buenaver says. You may want to try melatonin for sleep if you have difficulty for more than a night or two. Research shows that a supplement may help people with insomnia fall asleep slightly faster and may have bigger benefits for those with delayed sleep phase syndromefalling asleep very late and waking up late the next day.

What To Know About Dosage & When To Take It

HOW and WHEN to take Melatonin

Melatonin supplements contain anywhere from 0.5 to 10 milligrams of the hormone. “People often think the more I take, the more effective melatonin will be,” Gradisar observes. Indeed, the Journal of the American Medical Association found that taking more than 5 milligrams of melatonin per day has become more common in this country in the last two decades.

However, both Bonney and Bhopal generally recommend sticking to a lower dose. ” ‘less is more’ when it comes to melatonin, and typically recommend doses of one milligram or less, usually closer to 0.5,” says Bhopal.

“In fact, per the science, the physiological melatonin dosewhat’s in our body under normal circumstancesis only around 0.3 to 0.5 milligrams,” explains Ashley Jordan Ferira, Ph.D., RDN, mbg’s vice president of scientific affairs. “Put in that important context, people are megadosing on melatonin these days. It’s concerning,” she goes onto say.

And she’s not alone in her cautionary posture. “It’s important to remember that melatonin is a hormone, and using any hormone regularly can down-regulate your own production of that hormone,” notes Bonney. This is one reason it’s best to avoid taking high doses of melatoninespecially on a regular basis. Furthermore, “melatonin has the ability to impact other hormones, like estrogen and testosterone,” Ferira adds.

How Do Sleep Patches Work

Sleep patches work by allowing the ingredients to penetrate the skin and make their way into the bloodstream.

In laymans terms, the job of your skin is to keep things out,” says Sudha Tallavajhula, MD, sleep medicine neurologist at UTHealth Houston Neurosciences. “But if the drug/supplement is small enough, then it can transfer through the skin. As you sleep, the substance transfers to your body.

While all kinds of sleep patches havent been tested, studies on transdermal melatonin show it can be effective in transmitting the substances through your skin and into your system.

Some sleep patches also utilize sustained-release technology. This means they slowly transmit the ingredients into your bloodstream so you stay asleep throughout the night.

The argument here is that otherwise, the ingredients peak too early in your bloodstream and lose effectiveness later. However, there haven’t been enough studies done on oral versus sustained-release patch dosage in order to compare the two.

Specific instructions may vary based on the particular sleep patch you select. Typically, the process includes applying the patch about an hour before bedtimesimilar to taking an oral supplement.

Some brands recommend choosing an area that’s comfortable and as hair-free as possible, such as your forearm, shoulder, calf, or the top of your foot.

Are There Side Effects To Melatonin

The side effects of melatonin have not been studied in-depth. However, health experts believe that melatonin is probably safe for most healthy adults. The most common side effects reported by people taking melatonin are:

  • Feeling sleepy during the day
  • Strong nightmares
  • Temporary depression

People should not drive or operate heavy machinery within four to five hours after taking melatonin. Melatonin supplements should never be taken with alcohol or other sleeping pills as the combined effects may cause breathing problems or make people too sleepy.

Melatonin supplements may be unsafe for people who are trying to get pregnant. Health experts do not yet know whether melatonin is safe to take during pregnancy or while breastfeeding. People who are pregnant, trying to get pregnant or breastfeeding should speak to their doctors before starting melatonin supplements.

Melatonin supplements interact with many medications, including birth control pills, blood pressure medicine, antiseizure medicine, medicine to weaken the immune system, and blood thinners. People who take any of these medicines should speak to their doctor before trying melatonin supplements.
