Can You Overdose On Melatonin How To Determine The Right Dosage For You
Melatonin is natural, but taking too much of the supplement may lead to adverse side effects. Heres how to recognize signs of a potential overdose.
Tossing and turning night after night can take a toll on your mental and physical health. This can make you feel sluggish, irritable, and achy throughout the day. So naturally you might seek a sleep aid for better rest.
Some people see results with over-the-counter and prescription sleeping pills. But before going down this path, consider a natural approach, like melatonin supplements.
Melatonin is a neurohormone that controls our sleep-wake cycle, and many formulations and dosages are available over the counter, explains Ofer Jacobowitz, MD, PhD, an otolaryngologist and sleep expert based in New York City. It can be useful when you are trying to advance your bedtime, especially when combined with reducing light exposure two hours before bedtime.
Melatonin is naturally produced by the pineal gland and gradually released into your bloodstream as you prepare for sleep. But if your body doesnt produce enough of this hormone, you may have problems falling asleep or staying asleep.
Melatonin supplements are generally safe when taken appropriately, but it is possible to overdo it. Read on to learn how to recognize a melatonin overdose.
Melatonin Dose For Adults
Since melatonin is considered a supplement, its not regulated by the U.S. Food and Drug Administration . But if youre still interested in using the supplement, in most cases, Dr. Goldman suggests using the lowest dose possible for the shortest amount of time to achieve your desired outcome. In general, melatonin can be used in two ways.
Taking melatonin as a sleep aid
This method is meant to help you fall asleep faster in a very short amount of time. Dr. Goldman suggests starting with 1 mg, and then increasing that amount by 1 mg every week until youve reduced the amount of time it takes you to fall asleep. But you should know, this method isnt super effective because you can easily interrupt the melatonin process.
Its important to note that its really easy to overcome the effect of melatonin, says Dr. Goldman. If you take it and then get on your phone, go on social media, play video games or if you have an overactive mind thats racing or worrying, you will likely overpower the effect of melatonin.
For this reason, its best if you take melatonin when you start feeling tired and make sure you allow your body to be at full rest when you take it.
Taking melatonin to adjust your circadian rhythm
For these more chronic cases, Dr. Goldman suggests working with a sleep medicine physician or behavioral sleep medicine specialist to create a sleep-wake schedule that may include the use of melatonin.
Why Do Some People Need Extra Support To Sleep
Imagine youre traveling across the country, spanning a time zone or two along the way. It could wreak havoc on your sleep . Or what if you occasionally work the night shift, throwing your sleep/wake cycle completely off balance? But even something as common as stress might make it difficult to fall asleep or stay asleep sometimes. Taking a melatonin supplement may help in these instances.3 Practicing sleep hygiene tips for better sleep, such as reducing screen time at night, and going to bed at the same time each night may also help. Some people cant relax their mind as they wind down for the night.

Since then, higher doses of up to 10 mg have been made available on the market. Although recent evidence suggests that doses greater than 6 mg of melatonin provide little benefit, additional research is required to determine the specific doses of melatonin that may be supra-therapeutic and subsequently interfere with the natural sleep-wake cycle or worsen insomnia from receptor desensitization.4 Appropriate monitoring and recommendations should be made to limit the dose being used on a regular basis in elderly people.3,4
