How Much Melatonin Can You Take in a Day
Key Takeaways
- Melatonin is a peptide hormone that causes you to fall asleep, and has another properties similar being a very strong antioxidant.
- Although melatonin is sometimes thought of as a dangerous "cure all," it's just a very safe fashion to fall asleep faster, and the benefits and harms stop at that place.
- Melatonin supplements are keen for people who cannot fall asleep quickly and time-release formulations are perhaps proficient for people who wake upwardly during the night. The only effect is which melatonin dosage you want to take.
Dorsum in my day, steroids were evil.
Should never take them, they would literally make your liver shiv your spleen then sell your kidneys for drug money.
Testosterone enanthate, anastrozole, androstenedione … oh wow these big words are annoying—hormones, yeah, hormones are evil.
Ever wondered why the just (adept) dietetic joke for a few decades was "How practise you brand a hormone? Don't pay her!"
It'southward because steroids as well turn your gonads into sex workers, besides your lungs for some reason.
Hormones will kill you, end of story. Or so I was told.
Plough the clock frontward a decade and now we're feeding our kids hormones so they'll sleep better …
Clearly hyperbole, since the topic we're talking about is melatonin (technically a hormone sometimes given to kids) but I have to be honest—I have yet to run across a young mother who, upon learning melatonin is a hormone, gets thrown into a hilarious panic much to my bemusement. Curse these well educated consumers!
All concerns I've always seen well-nigh melatonin take been online, where I haven't been able to delight in their confusion, but ooooh boy are those criticisms online … over the top and repetitive.
It seems that the fearfulness of "hormones" in general is still very much alive despite us having the best example for an "exception to the dominion" in melatonin—the hormone that tin can't seem to hurt people.
The thing is, why in the seven hells is melatonin so absurdly safe? Why is it then hard, if non incommunicable, to observe an case of a melatonin overdose despite the dosage you take?
I'll be honest, I never expected information technology to be safety the first fourth dimension I read almost information technology.
Combining what I knew about hormones in full general, and how the body adapts to them (reducing synthesis of your own hormones) and what I knew most benzos (a class of pharmaceutical sleep aids that could legitimately kill you with withdrawal symptoms) I thought melatonin was going to be abomination.
Simply, nope, just a legit solid and safe chemical compound.

What Is Melatonin?
Melatonin is a peptide, or short amino acid chain, that's found in almost every plant and creature on our planet. A potent antioxidant, multifaceted, but all-time known for its role in slumber.
In humans, nosotros become the bulk of our melatonin from our diets. Not directly, nonetheless, but instead through consuming the amino acid chosen L-tryptophan.
This is the same amino acrid sometimes blamed for Thanksgiving-induced nutrient comas despite it being in similar levels in other meats—every bit if some people don't realize that eating copious amounts of anything volition get out you tired.
50-tryptophan's major part, equally far equally nosotros're concerned, is but being present in the body so information technology tin can be converted to the amino acid five-hydroxytryptophan (or 5-HTP which is a dietary supplement in its ain right) that's later converted to serotonin—a neurotransmitter.
Serotonin, then, can exist converted into melatonin on an equally-needed basis. The regulation is pretty simple, actually, and tin can be viewed as being in an "always on" state unless calorie-free is perceived through the eyes—in which example synthesis is suppressed and alertness results.
This is why darkness, regardless of the time of day, has the potential to brand y'all sleepy and why falling asleep in a well lit room is more hard than a nighttime one. It'due south an impairment of melatonin synthesis.
It should also be mentioned that this synthesis is somewhat brain specific, since the optics are incredibly close to neural tissue in part (in fact, some researchers consider everything except the eyeball itself to be part of the encephalon) and synthesis in other body parts is not heavily affected by lite.
Yup, despite being known every bit the sleepy hormone, melatonin is produced everywhere in the body that serotonin is produced. Largely in the gut, and then via the blood can become anywhere.
Unfortunately, sometimes simply eating protein to get a large amount of L-tryptophan is not plenty. Synthesis could exist disturbed, yous could want more than your body ordinarily makes, or some other variable comes up that could encourage supplementation.
Why Practise People Take Melatonin for Sleep?
Past far, the most popular usage of melatonin is for sleep disorders. It'south generally marketed for jet lag or "resetting" the circadian rhythm (our bodies internal perception of time) merely most ordinarily used for modest sleep problems equally a first line option.
Due to this, and due to it's easy availability (it'due south one of those supplements you tin can but buy in a supermarket) information technology has also been tested in sleep ailments like insomnia and sleep apnea.
Beyond the sleep outcome, other common reasons people seek out melatonin tend to float around either it's surprisingly potent antioxidant capacities (that, unfortunately, are not long lasting) and claims that it tin can increase growth hormone levels.
Unlike many supplements, due to the resounding success of melatonin in helping sleep there haven't been many other claims—no need to make stuff upwardly about information technology when it's a gold standard after all. Information technology seems to be typecast as "the" sleep hormone and almost nothing more.
What Are The Wellness Benefits of Melatonin?
All of melatonin's benefits pertain to slumber. It's rather difficult to put anything else in this section given the precedent they set—seriously, melatonin for sleep is strong and astoundingly well studied.
Melatonin and Sleep Latency
The major role for melatonin is that of reducing slumber latency.
When information technology comes to supplementing for sleep there are numerous parameters we can look at. Sleep elapsing (how long we stay asleep), sleep quality (how "effective" sleep is), and frequency of waking upwards during the nighttime—sleep latency is how long it takes to fall asleep.
If you lay downward in bed and, within five minutes, yous pass out then you lot accept great sleep latency. If it takes yous an hour of tossing and turning then yous take poor sleep latency—improving it would mean reducing slumber latency, which is the chief function of melatonin.
Run into, melatonin may be called "the" slumber hormone but it'south one of many. GABA and adenosine play big roles (as evidenced by benzodiazepine drugs and caffeine, respectively) and even glycine, an amino acid, seems to exist a neurotransmitter that helps with sleep.
Melatonin'due south specific role, it's specialty, is in inducing sleep. Making your eyelids heavy, making you lot lethargic, and starting the sleep process so other hormones can kick information technology upward a notch.
In these situations, supplementation of melatonin appears to be able to cause you to autumn asleep faster assuming yous had some impairment in sleep latency to brainstorm with—won't brand you fall asleep in 3 minutes if it unremarkably took you 5 but will brand you fall asleep in 10 if it normally took you 30.
If you think that's non too large of a bargain then you've probably never dealt with long term sleep problems—insomnia-light.
Melatonin and Jet Lag
Your trunk has an internal cyclic rhythm that'southward partially independent of external sources. In one case you brand a specific bedtime a habit then you will observe yourself getting sleepy at around that time each twenty-four hour period.
Which makes for many issues traveling across time zones when you lot want to stay awake and productive for many more hours that your body honestly did non expect. Our bodies didn't evolve to travel halfway around the damn world in less than a day later on all.
This is the problem of jet lag, lethargy that comes from travelling to different time zones because your own internal circadian rhythm did not readjust, and it'southward the most direct and practical awarding of melatonin since the inherent trouble is in improper sleep latency.
Interestingly enough, this isn't a low-cal issue. Fifty-fifty shift workers, and bullheaded people who cannot perceive light, suffer from the internal clock non lining up with the external clock. So where does melatonin, the low-cal responsive sleep hormone, play in?
Studies on melatonin and jet lag notice that melatonin works , and is currently among the best options (both supplemental and pharmaceutical) for helping you lot acclimatize to your new time zone. Simply put, the best awarding of the best purpose of this supplement.
Probably the best when you take safety into business relationship since Ambien works better but, hey, don't recommend benzodiazepines unless you have to after all.
Information technology'due south the only time I've ever seen a Cochrane meta-analysis utilise the give-and-take " remarkably ." These researchers are usually pessimistic fun destroyers (which is why I love them then much.)
This also applies to shift work , when the internal clock is thrown off, and some studies detect more benefit using caffeine in the morning with melatonin at night for condiment benefits.
Ultimately, melatonin is incredibly effective for whatsoever consequence pertaining to aberrant circadian rhythms. This usually refers to jet lag and shift work, and melatonin works very well to aid put you dorsum on track—possibly even better when paired with things that help you wake upwards, like caffeine, or maybe some low-cal therapies (red at dark, blue-dark-green in the morning.)
What Does Melatonin Not Practise?
In that location have been some sleep issues that melatonin is surprisingly ineffective at helping, and of course melatonin is at times used for reasons that take no scientific back up.
Melatonin and Sleep Quality
To get the well-nigh surprising, and conditional, out of the way beginning—melatonin does not improve sleep quality. At least, not inherently.
"Sleep quality" is a general term that's thought to reflect how benign slumber is for you. Sometimes you have a expert sleep, sometimes a bad one, and improving sleep quality is thought to help you lean towards proficient sleeps.
If you lot but sleep for 4 hours a night and, past using melatonin, you can get eight hours then of course overall sleep quality is going to increase—y'all have iv more hours of sleep! If time-release melatonin keeps you from waking up in the night then, yes, sleep quality increases .
While in that location are many people who can rightfully claim improvements in sleep quality from melatonin it's simply because they sleep more . What about situations where you do not technically sleep whatsoever more? People without issues with slumber latency?
Well, in these cases it seems that melatonin serves no further purpose.
In situations where melatonin does non improve sleep latency or keep you asleep there's no inherent increment in sleep quality.
For people with no issues with sleep latency, melatonin does not seem to take whatever major role. Well, it does, only your synthesis rates and slumber hygiene are top notch and supplements won't assist yous.
Melatonin and Growth Hormone
Growth hormone, like to melatonin, is a hormone that has a very "pulsatile" nature.
Information technology doesn't but go up and stay upward, it'southward levels over fourth dimension bounce like a sine curve at a nightclub. It besides goes up a lot when yous autumn asleep, like the stack of things beingness balanced on your head at a party.
So information technology may seem a scrap naive when people investigated a link between the two just on the footing of "hurr durr slumber causes growth hormone and melatonin cause sleep; melatonin crusade growth hormone?"
That, because every time I mock something it hits right back, evidence came back that melatonin does indeed increase growth hormone levels, peculiarly with do, and …
Await.
I've seen this before.
Studies have been conducted on supplements such as L-arginine and creatine finding increases in growth hormone merely, ultimately, these pocket-sized spikes over a short menstruum of fourth dimension mean nothing to a pulsatile hormone. We would need 24-hour increases which these studies do not detect and, in the case of melatonin, came back as a negative .
Melatonin is similar to L-arginine and creatine in concept—small spikes mean zero.
Nosotros know sort of why this is happening (dissimilar the aforementioned two supplements)—melatonin seems to resensitize the pituitary gland, an area of the brain central to some hormones, to growth-hormone releasing hormone. Similar to how L-arginine works past limiting growth hormone resistance.
And, of course, all of these take some weird shenanigans where at times they reduce growth hormone in response to exercise— creatine , L-arginine , and even melatonin .
Melatonin is a part of the "shenanigan trio" of supplements that are claimed to increase growth hormone, and technically can, but are involved in some weird balancing act where they may also decrease growth hormone—either mode, the changes are besides transient to matter much.
Melatonin and Antioxidation
Ane more than "technically correct but practically irrelevant" situation is melatonin as an antioxidant. I mean, it technically is—most dietary supplements are technically antioxidants.
Melatonin works both directly , being able to seek and neutralize free radicals (the term we use to refer to oxidants in the body) and can also work indirectly by supporting some antioxidant enzymes similar superoxide dismutase . Information technology'southward relatively potent also, with one written report assessing DNA damage noting it was stronger than resveratrol and dark-green tea catechins.
This, however, just brings up the question "Isn't my normal melatonin synthesis enough? What additional benefits would supplementation bring me?" To that question, I take no answer.
We practice have human studies showing a decrease in general and exercise-induced oxidation but the more I look into these studies the more than I think that they're just not practical.
Reducing coughs, reducing dorsum pain, those are practical takeaways.
Less oxidation though? Merely measuring a biomarker similar this is the furthest matter from "practical takeaway."
It would assistance, a scrap, if the main benefits of melatonin were tied into melatonin'southward antioxidant capacity but … they're not—the actions of melatonin equally a sleep-inducing hormone don't care about oxidation rates, simply its own receptor (the place melatonin activates like a key.)
Plus melatonin is eliminated from the body rather quickly so, even if we did desire a "just in case" antioxidant information technology doesn't piece of work as well well for this—you'd demand to accept information technology every other hour (melatonin has a half life between ane to 2 hours at normal doses) unlike something like grape seed extract that stays in your body for a long time.
Ultimately, melatonin seems to be a technically potent antioxidant but practically has a few shortcomings. Paired with how no proven benefits of melatonin, that are relevant, are directly linked to it's antioxidant profile mean that supplementation has all the same to prove whatever existent benefits.
What Is The Clinically Effective Melatonin Dosage?
For the purpose of this article I will be addressing, in depth, melatonin dosages for adults.
While melatonin is one of a few supplements with evidence of condom in children the best mode to find the right melatonin dosage for kids is pretty unproblematic—start low and increase until you reach the dose that keeps them incapacitated best.
That'due south nevertheless a good rule of thumb for adults just studies have already done that a lot. Luckily for us, we have a practiced idea of where this rule of pollex volition end up for you. In general:
- 300 mcg (0.3 mg) is usually seen every bit the lowest effective dose.
- 500 mcg (0.5 mg) is as well a depression constructive dose. Depression refers to dose, notwithstanding, not dominance—when information technology comes to people with no sleep issues this may exist the platonic dose.
- 1-3 mg is the nigh common range when it comes to supplements. Some people benefit from these doses more than the microgram doses, some don't.
- 5-ten mg accept been used, with success, in some slumber impairments that were nonresponsive to the 1-3 mg range.
- Megadoses beyond the above, upwards to 40 mg, have been tested and appear safe merely are not specifically linked to any unique benefits.
When it comes to melatonin doses, more than is not necessarily ameliorate.
As an annex, there's a specific form of melatonin tablet known as "time-release" where it slowly releases melatonin over the course of the dark rather than just immediately releasing it all at once. This class is best taken at 3 mg and is designed for people who continually wake upwards over the course of the night.
My personal recommendation is to consider both the 300 to 500 mcg range since, worst instance scenario, if yous need more than yous can just take more capsules, and peradventure also exam out the 3 mg fourth dimension-release to see what works for you.
If buying a supplement with other slumber support supplements then opt for a lower dose of melatonin.
Tin can Y'all Experience a Melatonin Overdose?
An overdose refers to when you take too much of a drug and either go unforeseen side-effects or yous go "too much of a good affair" and end up hurt.
For many supplements overdose is not too much of a concern, just some stomach problems and diarrhea since your body has built in refusal mechanisms in the intestines. However, when potency increases then overdose becomes more than relevant of a business—many supplements avoid overdose by simply being too weak to have any outcome, let lone too much of one.
Melatonin, withal, is uncommon in the sense that it is potent and rare in the fact that it does non seem to have a land of overdose—within reason, at least.
For a supplement that works at 300 mcg (0.iii mg) you would wait there to be side-effects when taken at twoscore mg, about 130 times the dose, but melatonin seems unable to cause acute impairment even in this situation.
The jury is yet out when it comes to taking those astronomical doses every single day for months, specially in the morning when melatonin is not supposed to be upwards, then don't practise that. As long as you follow the standard dosing instructions, though, it'southward hard (and perchance impossible) to overdose from melatonin.
Does Melatonin Have Any Side-Effects?
Melatonin, despite information technology technically being a hormone sold in grocery stores for kid consumption, is oddly safe. Like, incredibly safe.
At that place has yet to be a confirmed report of melatonin, inherently, causing significant harm to the user. Melatonin overdose seems quite unlikely for an adult (uncertain most children but if you're force feeding an adult super loaded dose of whatsoever drug or supplement to your kids then maybe consider calling the friendly neighborhood child protective services).
Now, this isn't to say that melatonin is completely side-effect complimentary simply the side effects nosotros take to bargain with are pretty laughable. If you take too much melatonin before you go to bed, or in a few cases are merely unlucky, then you may have some grogginess in the morning.
That'south information technology.
Melatonin was fifty-fifty able to avert the major "exercise not operate heavy mechanism while blah blah blah" event since taking melatonin supplementation in the morning when the lord's day or your role'southward fluorescent lights are bright seems to return it quite ineffective for sleep.
Of class, when things seem likewise proficient with already conducted scientific studies it's time to throw theories at information technology until it makes everybody sad. Could melatonin, theoretically, take any impairment?
Eh, mayhap?
The rubber of melatonin is best kept to the range of doses under 3 mg (and even more-so under 1 mg), so if you lot were to have ten mg every 24-hour interval for years then all suddenly a good chunk of the safety data no longer applies to you.
While we have a few studies showing that supplementing melatonin does not abnormally touch your own synthesis levels, superdosing paired with time is an untested brute. Could as well be harmless, could impair synthesis, nobody knows but not worth a risk in my opinion.
Y'all know a supplement is condom when you're trying to find harm with it, stretch the data as much equally you can, input a few theories and all you lot end upwardly saying is "maybe?"
When and How to Take Melatonin for Sleep Benefits
First, let'southward talk about the form of melatonin supplement that yous're using. Time-release or instant-release. Depending on which 1 y'all use recommendations differ.
Opt for instant-release (which we use in Lunar) if you want to be put to slumber pretty fast and opt for time-release if falling comatose isn't equally much an event as waking up numerous times throughout the night.
Instant release is taken before bed, but the timing tin change around a little flake. Beginning with taking it 30 minutes before your "platonic" sleep time and, during this fourth dimension, focus on creating an "ideal sleep environment." The 30 minutes can exist changed to your liking subsequently a bit of testing, any works best for you lot.
Time-release doesn't have precise dosing, since the event isn't instant, and because of this you also won't feel equally much (or any) astute sedation from the time-release form. Simply take it as close as y'all can to bed then it stays in your organisation as long as information technology tin can.
If you tend to take a snack before bed, and by before bed I hateful actually close to bed, and so use instant-release earlier you lot have your snack and expect about 10-20 minutes just and then they don't meet up in the stomach—this would slow down the melatonin's absorption and render it less-than-instant.
The above event does not affair with time-release melatonin. Y'all can put that stuff in your water ice cream if you lot wanted to and it would still work as intended.
Creating an Ideal Sleep Surroundings
Much like how melatonin taken earlier work in the morning time is rendered more often than not ineffective, if your sleep hygiene itself is horrible then y'all may not be able to maximize the benefits of melatonin.
So, at the very to the lowest degree, create a time frame before bed where y'all beginning to "cool off" a bit. Take measures to maximize melatonin—be it supplemental or your own synthesis. This includes stuff like:
- Stay away from fluorescent lights for about an hour earlier sleep.
- Utilise soft red lights to encourage melatonin synthesis. If you have a bathroom connected to the master bedroom then it'due south a perfect place for them (or just, yous know, get a table lamp simply that's not sexy.)
- Brand sure the room is comfortable, and perhaps a bit on the cooler side.
- Make sure at that place are no loud sounds you tin can hear when falling asleep (your ears remain open when sleeping, sound all the same affects you fifty-fifty later falling asleep.)
- Sleep in the same area each night, at roughly the same time, and don't acquaintance the room with much else beyond sleep and sexy times.
Truth be told, I believe that if you've tested out the 300 mcg to 3 mg range and melatonin all the same can't assist y'all fall asleep then information technology's your environment that's to blame … or the genetic monkey wrench, it comes up in the weirdest places.
The Bottom Line on Melatonin
Melatonin is a skilful example of what happens when nosotros get a large corporeality of data on a supplement. The times it benefits you go refined, and a lot of data on when not to accept it too surfaces.
Melatonin, at the stop of the solar day, is the GOLD STANDARD for reducing sleep latency, helpful for jet lag and shift work. It'south dominance is pharmaceutical in this realm, even to the indicate where medical doctors will tell you lot to get melatonin if yous have issues with sleep latency.
Other areas? Eh, astoundingly lacklustre.
Information technology doesn't assist with other sleep problems outside of reducing sleep latency (or at least, not to a relevant caste) nor does it increase growth hormone levels.
It's also surprisingly prophylactic, and melatonin overdoses are more or less unheard of. The but side effects are potential grogginess in the morn if you take likewise much or are perhaps unlucky.
It's a one trick pony just this pony has international pageant awards.
Oh, and if you're looking for a source of fast-interim melatonin that includes three other ingredients proven to amend sleep, and then yous want to check out Lunar today.
