Why Melatonin Is a Dangerous Supplement

Melatonin is a popular supplement for the sleep-deprived, namely because it carries rather innocent associations. Melatonin is “natural” and “safe” and “herbal”, right?

Wrong. I’ve been arguing with the melatonin prophets for years because I believe the image melatonin has, and what melatonin really is, are vastly different. Like so many things that we trust in, consume or think we understand, the truth may not be what we want to believe.

My caution with melatonin is simple: melatonin is a hormone.

That’s right – a hormone. Like estrogen. Like testosterone. And just like taking estrogen (whether it’s Hormone Replacement Therapy or the Pill) or testosterone therapy, melatonin comes with risks. Frequent melatonin use – especially in the typical dosage of 3-6 milligrams – can trigger a bit of a vicious cycle in the brain. Supplement with melatonin regularly to get to sleep, and your body is going to produce even less, creating even greater need for the hormone. It’s not that you can’t ever take melatonin; but I think it’s important that people understand the facts.

A caveat: While I am generally against using hormones (it’s not nice to fool Mother Nature), I am in favor of using the natural version of the hormone melatonin to “reset” the diurnal clock when traveling across time zones. Because, after all, you got there by fooling Mother Nature in the first place! Humans did not evolve a mechanism to adapt to changing time zones. Jet travel can be some of the most destructive stress you can encounter, especially the older you get.

In fact, a recent article in ScienceNow Daily News reported on the growing concern in the scientific community over the dangers of jet lag. Turns out it’s more serious than we previously realized. Jet lag increases risk of cancer, ulcers, and sleep disorders, as well as weakening the immune system. Now, this isn’t reason to stop traveling; simply be aware of the risks and take some smart precautions (drinking alcohol on the plane: not a good idea).

I travel frequently, and I don’t suffer from jet lag, because I use melatonin judiciously in these instances. I also have a few rules about travel (feel free to crib my notes):

- Once you’ve landed and checked in to your lodgings, immediately get an aerobic workout. This will help stimulate circulation, hormones and serotonin production – it’ll just be that much easier adjusting to the new time zone. Don’t tuck into a glass of wine or take a nap. Spend 30 minutes getting your heart racing instead.

- Eat a small, protein-rich meal that also includes some fiber. But keep it light so your body isn’t further stressed.

- Reset your watch and then… lie to yourself. Don’t think about it; just immediately adapt to the new time zone.

- Of course, the goal is to adjust as soon as possible to your new time zone. If you’re flying overnight or flying to a place where everyone else will have just finished sleeping, by all means, do what you can to nap on the plane or otherwise refresh yourself.

- Drink at least a quart of water your first day there (4 glasses).

- Go to bed when everyone else in your new time zone goes to bed, and take 3-6 milligrams of melatonin an hour before you plan to fall asleep to make that possible.

  1. I’ve just watched a very interesting documentary produced by Dr. David Suzuki on the Canadian television program “The Nature of Things” – episode entitled “Lights Out,” Those of you in the U.S. will likely be able to access this website through Netflix or via a similar format.

    http://www.cbc.ca/natureofthings/episode/lights-out.html

    This documentary addresses decades of collective research into the impact of melatonin reduction in industrialized societies. The emphasis of the research studies the correlation of blue light suppression in a 24-hour, artificially-lit world, as a possible antidote to the hormone’s suppression.

    I confess, I haven’t searched through all of the posts regarding melatonin; time does not allow, but thought I’d post this information in the event anyone was aware of these studies.

    There is also an American company that manufactures products (eg., eyeglasses, lights, screens, etc.) that reduce or eliminate the blue light end of the spectrum inherent in artificial lighting. Here’s the website for these products:

  4. I remember taking Melatonin, it felt great sleeping again every night, but then I started to get abdominal cramps, vivid dreams and drowsiness, I personally thought it was appendix because of the abdominal cramps, so I stopped taking the pill, after 3 days the abdominal pain subsided, after that scare I couldn’t sleep so I started to take the pill again right after I got better and wow did that come back, had almost every bad side effect, until I figured it out that it was Melatonin and got off of it completely, all I can say since everyone has a different body is that yes use the product with caution anyways it was probably my fault i was taking a ” Maximum Strength 5mg ” dosage and in case someone asks no I never had pain in my abdominal area before I started using

Ive been taking it for a solid week now and the dreams have been awful. Ive always had excelent dream control but lately its been nightmares. Is this normal?

  6. Excellent information in this essay!! It was just what I needed to read to confirm what happened to me at my last trans-cont. trip. It was a quick turnaround, 5 days, so I never really had chance to ‘catch up’ at new place. However, this time, it took me 5-6 days to recover—I was fatigued and felt like I needed to sleep a lot! I totally concur on the damage to the physiological system caused by our fast lanes, esp. on older people.

    Also, I agree, just common sense, that continuous use of the wonderful melatonin would cause rebound effects, and even though I’ve had trouble getting a good night’s sleep for some time, I plan to not use it as a crutch…or if so, will cut back to maybe .5 mg every now and then! Thanks! And yes, I get those weird dreams, too, but chalk it up to deep sleep.

  7. Doesn’t look like anyones been posting here for a while, but i’ll ask this anyway. So, i’m 17 years old, tonight i couldn’t sleep so i decided to take 30 mg of melatonin. Now i’m not sure if the symptoms i experienced could be from too much melatonin or not, all i know is somethings wrong. I fell asleep quite easily. When i woke up i was sweating, i could hardly breathe(chest was very tight) my heart was racing, around 120 bpm, and my heart was very weak. It’s been hours and my chest is still tight. I’m just wondering, if anyone knows.. Is this perhaps caused by too much melatonin? If not i’m totally out of ideas meh.

    • I hope you seen a doctor after experiencing those extreme symptoms! I’ve been taking melatonin for years but have realized I needed a smaller and smaller dose. Actually one 3mg pill can be 5 or more doses now and I assume will get smaller again. Too much in the past has caused adverse reactions with sleep, emotions and energy. I personally believe a person needs to get their own levels if melatonin to a normal state then maintain that with very small amounts. Too much melatonin after you’ve replenished yourself can cause adverse effects from my experience but it is definitely a wonderful synthetic hormone supplement if used properly for yourself.

  10. I have had sleep problems for over 20 years and started taking melatonin (under 3mg) about 15 years ago and then it stopped working, no matter what kind I took. And haven’t slept well since because it just wouldn’t work anymore. then got onto (2 or so times a week just to maintain sanity) ambien- which I really don’t like taking. And even when totally off of ambien for long periods of time, I don’t sleep still. Just found a melatonin that works again for me a few days ago. I am sleeping again and actually groggy (a little too much I admit but usually I am just not sleepy at all even though I am brain dead/body dead tired). I would rather take melatonin than die of sleep deprivation which I have been doing for years. I was tested many years ago and found that my body does not make melatonin for some reason, which could be why I don’t sleep anymore. I have aged a great deal, and I feel awful and my brain is pretty much mush most of the time unless I drink a ton of caffeine which makes my sleep worse of course so I only do that if I need to function very well, like driving, functioning normally, etc. Sometimes you just have to be ON. so anyway, I THANK GOD FOR MELATONIN!!!!

  12. I have had sleep disorders my entire life, even as an infant. No one caught on until I was almost 43 years old. I have several sleep disorders but the main 4 are sleep hypopnea (shallow breathing while sleeping), circadian rhythm disorder (I was born with this one), sleep Sleep paralysis, and sleep walking. The last two are pretty scary, the sleep paralysis because I’m paralyzed when I wake and feel like something is choking me and the sleep walking because I actually do things in my sleep like shut of heaters, hide things, and break things. On average I would wake up every 1 1/2 to 2 hours and be up for at least an hour before I could get back to sleep and was up for the day by 4am. NOT fun when your older. It didn’t seem to bother me when I was younger until I was told that the lack of sleep made my ADHD symptoms worse. I was put on C-pap last year for the sleep hypopnea and still was waking up every 1 1/2 to 2 hours. Was put on 150mg of Trazadone, which the doctor said was the strongest sleep medication with no result. It would make me tired, but would not keep me asleep. Finally he told me to take a 3mg tablet of melatonin an hour before bed. The first night I slept for 5 hours straight. For the first time in my life I was actually sleeping 5 hours straight without waking up. The sleep paralysis happens much less frequently, and I haven’t been sleep walking. The reduced frequency in sleep walking while taking melatonin has me wondering if it’s possible that lack of sleep has something to do with it, something I’ll have to ask the doc when I see him in January.
    I don’t believe everything I see online but I do understand the concern about the weight gain. I was constantly exhausted, still am since 5 hours is still not enough sleep for me. It is more than I was getting so I’m not complaining too much about that but I have gained weight over the years and still am. The doc says that it’s because I’m so tired all the time. If they can just get me to sleep at least 7 hours he says I’ll feel much better. Melatonin in my case has helped with life long sleep deprivation. Whether Melatonin itself causes weight gain I don’t know but it’s possible that it can in certain people since we all react differently to the different things we eat, breath, and touch. Just as an example, if you give Adderall to someone who does not have ADHD it will speed them up. If you give the same stimulant to someone like me who has ADHD it slows us down so that our bodies and brains can actually work together. Different reactions for different people. But it is proven that chronic lack of sleep can cause weight gain. I am not a doctor, will not pretend to be one, and am only stating my own experience and those things my doctor has told me. I’m not so judgmental when someone is suffering from something and trying to figure out what the cause is. Trying to figure out what is wrong can take years, in my case it took nearly 43 years. No one suspected sleep disorders, not even my parents and that’s despite the fact that I was always in trouble for snooping around the house while everyone was asleep and waking my parents up at 4 and 5 am every morning. Hopefully people reading threads like this will realize that most comments are opinions based on experience and should not be taken as medical advice. Your doctor is the best person to talk to regarding any medical issues.

    • I have severe insomnia and the only thing that helps me to sleep is Ambien CR, (not the generic version as it doesn’t work the same for me)12.5 mg (that is the time release version of ambien). It helps me sleep 6 to 7 hours. However I can only tolerate it a couple times a week at most, so I am most always sleep deprived. I have been taking 3 mg of sublingual melatonin each night now (the regular pill you swallow doesn’t work for me at all, can’t even tell I took it) but I still wake up about every 1 or 2 hours and so each time I wake up I have to take more sublingual melatonin. I also use an oil to help my restless let syndrome each time I wake up. I used to take melatonin a couple of years ago but it stopped working for some unknown reason, then about 2 weeks ago I got a new one and it worked again. I wish so much it would keep me sleeping longer but at least I am not up all night only to sleep 3 hours in the morning which is what happens and if i let that happen i begin sleeping in later and later in the morning. I am hoping that taking that much melatonin is ok. I doesn’t affect my weight at all. Sleep deprivation has ruined my health. I am happy to take whatever works if i am able to tolerate it and not feel totally miserable the next day.

  17. I’m in my late 40s, and a martyr to insomnia. I’ve been buying melatonin whilst visiting the States, and using it at home (6-9mg pd 1 hour before bed) to regulate my sleep. I’ve been doing this for a number of years now, probably around seven.

    It’s changed my life.

    I get to choose when I sleep. I sleep well, naturally. I wake up refreshed.

    The key thing to note with melatonin is that, as has been pointed out, it’s a hormone. It should be produced in the pineal gland, but the body makes less as you get older. You can’t treat it like a sleeping pill. If you take it at a different time every day, it’ll be like living in a different time zone every day: your system’s going to get hellishly confused, and you’ll get jet lag symptoms. You MUST take it at the same dose, at the same time, every day. If you miss your time by more than about an hour, just don’t take it – use diphenhydramine, or something else, instead, and perhaps have to tough out a day when you didn’t sleep as well, until you can get back to the normal pattern.

    If you’re prone to depression that’s unlinked to irregular sleep, and you can’t be sure you can take the dose at the same time every day, think twice about taking melatonin. A confused sleep cycle can exacerbate depressive illness.

    But, you know what? I bless the stuff, and the FDA who allow it to be sold without prescription. Without it, I’d be a mess.

  18. I wanted to put in my two cents about how Melatonin has helped me. I am a natural “night owl” and Melatonin is the only thing that puts me’ in control of my bed time. On vacation, I stay up late and sleep late, but when I don’t have flexibility, I take 9 mg 1/2 hour before I want to fall asleep. I read or do crossword puzzles and then a feeling of sleepiness comes over me. I have not had one instance in the past few years that Melatonin did not work. If I ignore the sleepiness and keep reading or doing an activity, it wears off. It seems that the main effect is to produce a temporary sleepy feeling that is probably what “normal” people feel in the evening.

Melatonin works at 6mg for me but makes me feel horribly tired next day. Also blue light blocking glasses dont produce melatonin, they prevent breakdown of it. I can totally beleive the weight gain and loss stories bc everyone has a dif body. Sorry typos, grammar, mobile.

  22. I’ve used melatonin for a decade. Never had an issue. I have always used 3mg. I have been through stages where I haven’t taken for quite some time (3 months even). I definitely didn’t find it “more” difficult to sleep either… So for myself I’ve never had an issue and it has always worked well for me. I haven’t taken it for a year either. I only ever do now if I really can’t sleep.

  24. How timely is this article for me? I began taking melatonin (~ 5 – 10 mg) nightly, 2 months ago. I adhere to a 90-10 Paleo lifestyle and participate in various activities several times a week, i.e. Crossfit, climbing, hiking, etc.

    I was at my optimal weight/size and quite happy. I have packed on 20 pounds over a course of 1.5 months and have not been able to figure out what I was doing wrong! I have felt extremely ‘hormonal’ lately but assumed I was jumped in on my office mate’s cycle. I am going to stop taking melatonin (and hope I can get to sleep somehow) and see how I feel and look in a month!

  25. I AM a medical professional & would like to point out that each person is an individual and responds to medications differently. There is not one medication that affects everyone in the same way. Side effects posted as possible reactions to medications are very widespread & even contradict each other ie: constipation or diarrhea. Response to medications in clinical trials are based on the most common effects in a trial group study. Not everyone responds positively 100% in group studies, especially human trials.
    My own experience with Melatonin 3 mg each night was positive as it allowed me to get to sleep. However, as an individual, I did experience a most unpleasant side effect 2 months after starting this hormone which caused me to discontinue using it permanently. In my case I did not experience weight gain. I did however experience 8 lbs of weight loss after the Melatonin caused watery diarrhea up to 10 times daily for 7 weeks before I finally figured out what the culprit was. At no time did I suspect Melatonin. I had stool tests which were all negative until I happened across a forum where at least 20 people had experienced the same problem. There is product information that Melatonin can cause diarrhea, but as it did not occur for 3 months I did not suspect Melatonin.
    We all react differently to medications. This was a lousy way to lose weight and I am only posting this so that you will respect each other’s individualities & accept that each person can & will respond to a medication differently. The day following my stopping this medication was the day I finally started to get better. It is certainly not a medication I would ever take again even at a lower dose. The side effect was far too severe & debilitating and was difficult to diagnose. For those of you who wish to take Melatonin & are finding it helpful, I am happy for you. For those of you who are experiencing side effects, stop it & take melatonin under the direction of a Doctor. This hormone is not FDA approved for your safety just as all “natural” supplements do not require this scrutiny. As long as you know what you are taking, medication interactions with other meds you are on & the side effects of these supplements you are considered knowledgeable & informed. Educate yourself…in my case it did not pay off until I was educated on a Forum…and make your own decision on what is right for you. The squabbling at the beginning of this Forum was in poor taste. We are NOT all the same.

  27. Some interesting comments in this thread, and also some rather rude ones, play nice everybody!
    I’ve always had some very strange reactions to various drugs, so whilst I am guided by what is the norm I have also learned that the norm does not alway apply to me – I think that is why we are called individuals…
    As a 140lb male I can take a dose (or 3..) of a sleeping pill my doctor assures me is strong enough to knock out a horse, but I will still be wide awake all night.
    I have been taking melatonin for the past couple of months, and whilst my sleep has been much improved, I have had some very noticeable weight gain.
    Ok, so my conclusion is not that the melatonin is causing the weight gain, at least not yet, but I suspect it will be, for me as an individual.
    I am rather OCD, I eat exactly the same foods, same qtys, at the same time all the time, exercise vigorously 6 times a week, at the same time, get up at the same time everyday, go to bed at the same time every night…are you getting the picture?
    Taking melatonin is the only factor I can identify that has changed in anything I do. I don’t cheat with my diet, I don’t ever, and I mean ever, skip my exercise routine.
    I’m going to stop taking melatonin immediately, and see what happens with my weight. If my weight gain stops and my weight returns to what it was pre melatonin, then I will definitely drawing the conclusion that melatonin is causing my weight gain.

  28. I’ve been taking 2.5 mg melatonin. For about a month now, no weight gain at all, I must say I’ve never been calmer in my life! Anxiety, overreacting, hurtfulness, misery and euphoria – all diminished, my mood is mostly a stable straight line in between both the very high and very low – and before I’d be either on top, or at the bottom. I am happy with melatonin. Though I am concerned, what comes next. I’m extra careful about supplements for brain, especially when it’s hormones. At least this one does not have so many and so severe side effects as say diazepam, of which I have not taken a pill in my life due to those side effects. Rather I went through my misery in painful way. Melatonin does make it easier to have calmer thoughts, without being bothered by pervasive negative automatic thoughts, and helps me sleep better and to better remember my dreams. Also work with dreams has become easier, I do understand most of the times now that it’s a dream, much more than before :)

  29. I wonder if tart cherry juice concentrate has the same effect? I suffer from fragmented sleep caused by anxiety, and started drinking cherry concentrate for the melatonin every day to help ween myself off of Xanax – It worked really well for me (taking it every day 2TBS), increased my sleep fragments from 1.5 hours to around 4, AND kept a lot of the inflammation from my running routine (I run marathons) at a real low….but lately I’ve been feeling abnormally depressed.
    Crying all the time, thoughts of suicide- now I’m normally a very anxious person with low-grade depression (hence the xanax) but even this was out of league for me. I stopped taking the juice for about a week and although my sleep problems are creeping back, my brain is not so sad and angry- I think more clearly and rationally, and have stopped the chronic tears.

    Everything online says go nuts with the tart cherry juice but I wonder how much is too much….

  30. I used Melatonin because i drank too much coffee. Used it for years, not every night tho, I never gained any weight or had after effects from it. Unless you eat big meals after 7pm or later. When you first take them, you will feel drowsy the next morning. It did help me get to sleep without tossing and turning all night. also when i was down with the flu or sick. I only took half of the 3mg, unless i wanted to sleep sound i’d take the whole 3mg. Also, gave me nice vivid dreams.

  33. MY INSOMNIA IS CURED after 15yr fight

    I posted here several times regarding how Melatonin and other supplements have helped me fight insomnia.

    I thought I was “cured” several times. It turned out I never really was. Until recently.

    It’s been several months now and I sleep like a rock every day. What did I do differently?

    First of all no more in Melatonin. No more other sleep aids either.

    I simply a lot of of vegetables every day. Those highest in vitamin K. The most nutrient dense I can find.

    It also helped clear up a heart condition that I had, a blocked artery. Cleared up blood clots in my lungs. All possibly caused because of long history of insomnia and Snoring. Both have cleared up as well – What else is there to say.

  34. I happen to agree with weight gain. Took it for about 1-2 months and been working out and couldn’t lose 5 lbs that I gained. It increased my appetite. And same with my coworker. You can’t argue (in my opinion) that it doesn’t affect weight, as all bodies are different, so the effects are different. Let’s see if I lose the weight now that I’ve quit it? I just want others out there to know of my experience so that they can make their own decisions.

  35. I’ve also had the oddest of dreams while on the supplement.

  36. I love melatonin, I take it once in awhile when I know I need a good sleep.

  37. Agree with Rene – hormones are hormones and they are dangerous in the wrong dosage – this goes for Melatonin – Estrogen – Estradiol – Progesterone – Testosterone and even Vitamin D – when you disrupt your body’s natural rhythm and upset your hormones than several things can occur – depression, loss of energy, muddled thoughts, and yes, weight gain. Never ASAUME that any of these people on the discussion board are over-eating, or eating junk food, all of them have pretty much stated that they are below aver ah weight and live healthy, and fairly athletic lives. I am a former National-Level Powerlifter and Bodybuilder, I can tell you exactly first-hand what happens when you mess with hormones, and yes, I’ve tried melatonin, but I’ve also tried Clenbuterol too, which speeds up your body’s metabolism and heats your inner core temperature, in the short term, you do lose weight and have more defined muscle-tone, but in the long run you end up gaining weight because you’ve played around with your body’s own rhythmic hormonal cycle. Now I’m in my 40′s and still maintain a 120 lbs. physique, but I do not do any hormonal disrupting drugs anymore, and it’s taken years to repair the damage. Consult your Doctor for testing your hormonal levels before taking anything that may throw your internal system out of sync.

  39. Is there any actual research that the body produces less melatonin when supplementing? It sounds like one of those things that sounds true, but is there any data to confirm this? Also consider that light is a “lie”. We aren’t meant to view artificial lights. Orange lenses just address what we presently understand about how light affects the circadian rhythm, but we are many to experience the day as it really is. This screws with melatonin, most people likely don’t make enough. I can’t sleep well without 15 milligrams of melatonin. 9 is better than nothing, and 15 is a good number for me. I sleep great and wake up cheerful.

  40. Also vitamin d is a hormone. Hormone doesn’t have to be a dirty word. I’ve read of a few studies where participants were given hundreds of milligrams supposedly with no ill effects. You’ll have to find the study yourself it’s been a while.

    I’ve taken some brands of melatonin that make me feel weird. And others that work. I take gnc time release. They look at me odd when I go in there, because I know exactly where my stuff is and I don’t browse like everyone else. Also, those people tend to hand out medical advice or certain health claims like chromium helping weight loss and such. I just ignore them and get my stuff. Liquid Valerian is one component in a cocktail I take for panic attacks. I buy their fish oil too because if you buy three it works out cheap and I take twenty basic strength caps per day. Then my melatonin.
