The Right Melatonin Dosage
It's Not What You Think

The right Melatonin Dosage is different for different people in different situation depending upon who you are and what benefits you are intending to get from melatonin dosing. Interestingly, there have been studies using melatonin doses that are very small to a melatonin dosage as much as Three Thousand Times larger than the smallest dose- with VERY different outcomes, but all with extraordinarily few problems or Melatonin Side Effects.




When to Take Melatonin

Because melatonin is a hormone that is naturally produced by the body at night in order to help induce sleep, it MUST, without exception, be taken at night about 1/2 hour before sleep. Melatonin can make you SLEEPY, that's what it does. This is not a 'Side Effect of Melatonin' as some people say, it is an EFFECT, so please be prepared for it to put you to sleep and only take it before bedtime when you can get a full 8 hours sleep.

Melatonin Dosage for Insomnia

The right melatonin dose depends upon what you are using it for, but since melatonin is most often used as help for insomnia, then we'll start with melatonin dosing that have been shown to be of help for insomnia. Melatonin Benefits have been studied extensively as help for insomnia in just about all age groups from children to the elderly with few problems noted, but it seems to work differently at different dosages with larger doses not necessarily better for insomnia help.

Dosage for Adults

Melatonin dosing doesn't appear to be different for adults or the elderly. Dosages of Melatonin for Sleep have been from 0.1 to 20 mg that have effectively restored sleep pattern problems. One study that found dosages of 0.1 mg, that's just 1/10 of one milligram, to have significant improvements in sleep problems compared melatonin blood levels against a group of healthy people WITHOUT sleep problems.  They found that such a tiny dose was not only effective for sleep, but actually increased melatonin blood levels to the same range as the healthy people with no sleeping problems.(3) 

In fact, when melatonin was first discovered by MIT scientists, the university patented dosages between 0.3 mg and 1 mg because they never imagined people would be taking dosages more than 3 times higher than the 'physiologic dose' of 0.3 mg. Ironically, it is BECAUSE MIT patented these tiny dosages that supplement companies make higher dosages. It's not that higher dosages are better for you, it's just that they would have to pay MIT a patent fee if they made their product in the range indicated in the patent!

Remember, melatonin is a hormone. When hormones are taken rather than made by the body, the body applies a feedback loop and often stops making these hormones itself in a reverse rebound effect. So, taking more than the smallest effective dose is often a very bad idea when it comes to hormones like melatonin



But higher melatonin dosing is not necessarily better, and may be even WORSE than the tiny dosage of 0.1 mg that was used. In a study of elderly people with sleep disorders, a dosage of 0.3 mg (equal to melatonin 300 mcg) improved sleep significantly, but meltonin dosing 10 times larger of a full 3 mg given was actually NOT as effective(1). In another study, a blind person with 'sleep entrainment' problems was unable to 'entrain' his sleep with 10 mg even though the rest of a group with the same problem was able to. They increased his dose to 20 mg without any improvement in sleep. But when they Decreased his melatonin dosage to 0.5 mg, his sleep significantly improved!(2)

The right melatonin dosage depends upon what you are using it for

Therefore, it seems that a small melatonin dosage in the range from 0.1 mg to 3 mg is usually just as effective, and sometimes more effective, than larger doses.

Even though there is virtually no reason to worry about Melatonin Overdose or Melatonin Addiction with higher doses, they may just simply not be needed

What about Massive Doses?

As I said, different melatonin dosages have different effects and melatonin has even been studied at SUPER high dosages of up to 300 mg a day for several months at a time (4), with doses of 75 mg given safely for as long as 3 years at a time. And at these dosages, while there were no cases of Melatonin Overdose, it has actually been used as, and is in the final stages of a clinical trial for, a female contraceptive! Since melatonin has been used for this purpose and may be quite effective, it's best that women trying to get pregnant or who are pregnant should not use melatonin until its known if it's safe to do so.


Melatonin for Children

There have been MANY different studies using Melatonin for Children with sleeping disorders, especially in children with autism. Dosages used have been in the range of 0.1 mg up to 6 mg with good results at improving their sleeping problems. Melatonin appears to be safe and effective even in children with severe disability, those who are taking psychotropic drugs and in those who have a history of seizures.

In fact, it has even been used in hospitals for critically ill infants and has been used in some children as a TREATMENT for seizures when nothing else was effective.(3)(5).
