I’ve been a health care provider for over 20 years, 12 of which had been devoted completely to the apply of sleep medication. Over time, I’ve seen an unlimited enhance in the usage of melatonin by my sufferers and their households. Though melatonin has helped lots of my sufferers, there are some issues that I’ve which can be price sharing.


First, I’m not positive most of my sufferers that took melatonin earlier than my scientific analysis knew precisely what melatonin was. Melatonin is a hormone produced by a gland within the mind known as the pineal gland. The primary operate of melatonin is sleep regulation.

Melatonin ranges enhance in response to darkness, telling the mind that night time has arrived and it’s time to sleep. When there’s brilliant gentle, as within the morning, melatonin manufacturing shuts down and the mind is aware of that it’s daytime.

The day-night regulation properties of melatonin and lightweight make them the 2 key elements within the institution of the interior sleep-wake clock, or what known as the “circadian cycle”.

A circadian dysfunction happens when there’s a mismatch between the interior clock and the socially accepted time to fall asleep or to get up, as is seen when somebody travels throughout time zones and has jet lag. However jet lag generally can happen within the absence of journey. For instance, while you stay in an surroundings of brilliant lights till late hours of the night time, you idiot your mind into considering that it’s nonetheless daytime.


On this case, melatonin manufacturing doesn’t happen and you do not really feel sleepy till the late hours of the night time, or generally early hours within the morning.

I’ve seen many youngsters come to my clinic as a result of they can not sleep till 2 am or three am, however they’re up watching movies on their digital gadgets till late at night time.

I normally suggest my sufferers flip the lights off at an inexpensive time and count on sleepiness to start out occurring inside one hour. Nevertheless it takes time for the pure clock to regulate to a brand new schedule, and sometimes my sufferers desire to make use of a melatonin complement to quicken the circadian time adjustment.

With the rise in use of digital gadgets, sleep issues have turn out to be fairly widespread and melatonin use has elevated. Due to its sleep-promoting properties, melatonin can also be an extremely engaging possibility for individuals who endure from insomnia or sleep disruption.

Over-the-counter melatonin

In some nations, such because the US, melatonin may be purchased and not using a prescription. This example issues me as a result of a scarcity of regulation can imply an elevated threat of taking a distinct dose or substances than these reported.

The truth is, a examine of melatonin dietary supplements discovered that the content material of the hormone ranged from -83 % to +478 % of the labelled content material. The researchers additionally discovered different substances that weren’t reported to be within the preparation, together with serotonin and valerian.


Within the EU, the UK, Canada and Australia, melatonin is obtained solely by prescription for the short-term remedy of insomnia. This method permits for higher regulation, understanding and rationalization of dangers, advantages and options to the usage of melatonin.

Regardless that melatonin is a naturally occurring hormone, it doesn’t come with out side-effects, the commonest being complications and dizziness. It may possibly additionally work together with different medicines, similar to anticoagulants (medicine that assist stop blood clots).

The greatest proof of security for the usage of melatonin is for short-term use solely (one to a few months) and in low doses (0.5-1mg). The long-term results of melatonin stay unknown.

Have I used melatonin or really helpful it to my sufferers? Completely. However solely after I know precisely what I’m recommending it for. Insomnia could be a symptom of a sleep problem like stressed legs syndrome or obstructive sleep apnea, or it may be a symptom of one other situation, similar to despair, bronchial asthma or ache.

When a sleep specialist identifies the proper analysis, then the remedy choices may be explored. After I have to prescribe melatonin, I normally suggest beginning with the bottom dose attainable (0.5 mg) one to 2 hours earlier than their present bedtime, and I like to recommend that the affected person turns their lights off, or dims them, earlier than taking melatonin. I additionally suggest avoiding different contributors to poor sleep, similar to caffeinated merchandise after three pm, heavy train within the night, or the usage of digital gadgets earlier than bedtime.
