A: Taking the sleep hormone melatonin is recommended to help induce sleep, but there is a good deal of confusion about how much to take.

The hormone serotonin is produced during the day and this changes to melatonin when it gets dark outside. Peak levels of melatonin are produced before 3 a.m., when it sharply decreases before natural daylight returns. ;

Research has found that taking melatonin in low doses is the most effective way to promote sleep if you are experiencing restlessness or insomnia. Recommended doses of melatonin are from 0.5 mg up to 3 mg, which are adequate to promote sleep or treat jet lag.

When melatonin is used at higher doses, it tends to increase daytime sleepiness. Other side effects of too much melatonin can include reduced focus and concentration, feeling chilled and higher prolactin levels.

If you find yourself taking higher doses of melatonin, you can decrease the dose by cutting your tablet in half or in quarters. Research indicates there are no side effects if you reduce the dose of melatonin you are taking.

Americans arent sleeping well. Roughly 80% of U.S. adults say they struggle to fall asleep at least one night a week, according to a recent Consumer Reports survey. And research has found that sleep problems are also on the rise among adolescents.

While the causes of Americas sleep woes are up for debate, theres little disagreement about Americas favorite remedy: Melatonin, the countrys most-used sleep aid.

What Is Melatonin And How Does It Work

Research suggests that melatonin plays other important roles in the body beyond sleep. However, these effects are not fully understood.

Melatonin dietary supplements can be made from animals or microorganisms, but most often theyâre made synthetically. The information below is about melatonin dietary supplements.

  • Melatonin, according to more than 24 studies, is safe for children and has been used with little to no side effects. NaturalSleep.org
  • Currently, we dont have any evidence to say that taking melatonin on a daily basis in that sense is harmful, although there are no large-scale multicenter clinical trials to really test that.Medscape

This last quote is probably closest to where we actuallyare. However, it is clear there has been a dramatic increase in use ofmelatonin in children in the past five years or so. For example, in England, estimates have found a 25percent increase in melatonin prescriptions in children under 18 between2015-16 and 2017-18, and a 40 percent increase in the extended release formsduring the same period. There are no similar statistics in the U.S. forover-the-counter melatonin, but it is now rare in our experience that childrencoming to the Boston Childrens Sleep Clinic with insomnia are not already onmelatonin, usually recommended by their pediatrician.;

    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 Science Behind Melatonin

    Melatonin Dosage – Microdosing Melatonin – Why Most People Do it Wrong and My Solution

    Melatonin , chemically N-acetyl-5-methoxytryptamine, is a substance found in animals, plants, fungi and bacteria. In animals, its a hormone that anticipates the daily onset of darkness.

    In animals, melatonin is involved in the synchronization of the circadian rhythms of physiological functions including sleep timing, blood pressure regulation, seasonal reproduction and many others. Many of its biological effects in animals are produced through activation of melatonin receptors, while others are due to its role as a pervasive and powerful antioxidant, with a particular role in the protection of nuclear and mitochondrial DNA.

    The hormone can be used as a sleep aid and in the treatment of some sleep disorders. It can be taken orally in liquid form as well as capsules or tablets in immediate- or prolonged-release form. It is also available in a form to be used sublingually, and as transdermal patches. Melatonin is sold as an over-the-counter sleep aid in the U.S. and Canada. In other countries it may require a prescription or it may be unavailable.
