What Is The Highest Mg Of Melatonin

Is It Safe To Take Melatonin With Alcohol

What are the pros and cons of using melatonin for sleep?

Alcohol can disrupt your natural melatonin levels, so experts recommend against taking melatonin when drinking or when using other sleep medications.

There is limited evidence that melatonin might be helpful in recovering from alcohol use disorders due to the antioxidant effects of melatonin. However, more research needs to be done.

What Is The Highest Dose Of Melatonin Ive Ever Taken

I could be inaccurate in my recollection , but I think I administered about 50 mg melatonin within a ~12-hour window.

The melatonin was administered along with other substances mostly magnesium .

I took 30 mg melatonin about 30 minutes before going to bed. Then each of the 2 times I woke up in the middle of the night I took an additional 10 mg.

In any regard, what were the subjective effects I experienced from taking high-dose melatonin?

I suspect my reactions are probably similar for most people taking equipotent doses

  • Sleepiness & higher sleep inertia/drive
  • Altered state of consciousness
  • Depersonalization
  • Subjectively improved sleep relative to without

What was the point of taking such a high amount of melatonin in a short period of time?

Partly because I thought it would help my body recover from hyperarousal and Acute Stress Disorder.

Taking melatonin at high-doses liberally definitely helped subjectively I felt as though my sleep quality was much higher relative to lower doses.

Note: I cannot be sure that all of these effects were solely from melatonin as other supplements were co-administered. That said, my melatonin dosage was significantly higher than usual.

Is Melatonin Safe For Children

Further research is needed regarding the safety of melatonin for children.

Nearly 25% of children have difficulty sleeping, and parents increasingly turn to melatonin for help. Between 2007 and 2012, pediatric melatonin use rose seven-fold and is now the second most common natural supplement in this age group.

Despite its prevalence, there are reasons for parents to be cautious about using melatonin. It appears that children may be particularly vulnerable to the possible effects of this supplement on reproductive hormones. Melatonin has been associated with puberty delays, irregular menstruation, and overproduction of the hormone prolactin. It is important to note, however, that research on this topic is conflicting, and experts agree that the topic is understudied.

Parents should also be aware that melatonin may . Children taking other medications or who have illnesses affecting these systems should consult their doctor before starting melatonin.

Melatonin should only be used for children under the guidance of a doctor. Most pediatric sleep disorders can be managed with behavioral changes, such as proper sleep hygiene and cognitive therapy. Melatonin should not be used before trying other measures.

Are High Doses And Megadoses Of Melatonin Toxic To The Body

No . In fact, high doses seem to protect the body to a greater extent against cytotoxins and neurotoxins as a result of more potent anti-oxidative and anti-inflammatory actions.

According to some researchers: The lethal dose 50 of melatonin is reported to be infinity i.e., it is impossible to administer a large enough dose of melatonin to kill an animal.

Theres probably a sweet spot type dosing range wherein more melatonin might be disadvantageous, counterproductive, or offer such a diminishing return that it makes no sense to administer more.

There is one study I found in which high-dose melatonin was worse than low-dose melatonin with regard to preventing aminoglycoside ototoxicity.

Melatonin And Kids With Adhd


Attention deficit hyperactivity is commonly associated with sleep problems, just as sleep problems can cause attentional issues. As many as 70% of children with ADHD may have sleep problems. Sleep problems include difficulty falling asleep, abnormalities in sleep architecture , and daytime sleepiness. Trials of melatonin showed that it helped children with ADHD to fall asleep more quickly, although there was no evidence of improvement in attentional symptoms during the day. Side effects reported included problems with waking up at night and daytime sleepiness in some children. There is a nice review article here.

What Is The Dosage For Melatonin

Melatonin is a hormone naturally produced in your brain. Its best-known purpose is its role in helping you sleep better. You can also take additional melatonin as an over-the-counter dietary supplement to help regulate your sleep-wake cycle .

The U.S. Food and Drug Administration considers melatonin to be a dietary supplement, not a medication, so there are no official dosing guidelines for treating sleep disorders with melatonin. There are some broad guidelines you can follow, however.

Is Melatonin Safe For Long

According to the National Center for Complementary and Integrative Health, more research is needed to determine whether melatonin is safe for long-term use .

If you find that youre relying on nightly doses, it may be more effective to talk with a healthcare professional about any potential underlying sleep disorders or health conditions that may be the root cause.

Cognitive Enhancement & Preservation

Melatonin may be useful as a substance to enhance cognition and may prevent or delay onset of neurodegenerative conditions.

  • Cardinali et al. : Melatonin can be a useful add-on drug for treating mild-cognitive impairment in a clinic environment.
  • Data from a series of 61 patients with mild-cognitive impairment who received 3-24 mg melatonin at bedtime suggest melatonin significantly improves cognition.
  • Studies in MCI with melatonin doses in the range of 75-100 mg/day are further warranted.

Although numerous studies have found standard doses effective for the treatment of cognitive decline/impairment other research supports the use of high doses.

Its unclear as to whether melatonin dosing discrepancies yield significantly different: magnitudes of cognitive enhancement and/or effects on specific cognitive domains.

  • Sumsuzzman et al. : Meta-analysis indicates that melatonin is effective in the treatment of mild stage Alzheimers disease . Dosages administered in trials included within the meta-analysis ranged from 5 mg to 80 mg but it remained unclear as to whether high-doses differ in effect from lower doses.
  • Sleep Easy With Or Without Melatonin Supplements

    My Experience with High Dose Melatonin for Metastatic Breast Cancer

    Melatonin supplements are useful in rare occasions â like when battling jetlag or adjusting to a new sleep schedule. In these cases, itâs best to start with a lower dose of 5mg or less.

    Most of the time, however, you donât need any melatonin at all. Boost your brain’s own supply of the hormone by maintaining excellent sleep hygiene and syncing up your sleep schedule with your circadian rhythm.

    RISE can make those things easy by reminding you when to do 20+ sleep hygiene behaviors, and predicting the timing of your circadian rhythm each day. With a few lifestyle tweaks, you may find yourself drifting off easier, getting the sleep you need each night, and having more energy each day, all without melatonin supplements at all.

    What Is A Safe Melatonin Dose

    According to Michael Grandner, director of the Sleep and Health Research Program at the University of Arizona, melatonin is very safe if taken in normal doses, which is anything between 0.5 mg and 5 mg.

    A 0.5 mg dose may be all thats needed for sleep-cycle regulation, and should be taken three to five hours before bed, he says. For people who want to take melatonin just before bed, a 5 mg dose is appropriate. Some people report headaches or stomach problems at higher doses, but those side-effects are uncommon, he says.

    Still, there are other concerns. Melatonin has an incredible safety record, no doubt about it, says Dr. Mark Moyad, the Jenkins/Pomkempner director of preventive and alternative medicine at the University of Michigan. But its a hormone, and you dont want to mess around with hormones until you know what theyre doing.

    People with existing medical problems should discuss melatonin with their doctor before using it. While some research has found that melatonin may help treat hyperglycemia in people with diabetes, for example, other studies have shown that, in diabetes patients who carry certain genetic traits, melatonin may interfere with glucose regulation. Its these sorts of contradictory findings that give experts pause when it comes to issuing melatonin a full-throated endorsement.

    What Are The Benefits Of Melatonin For Sleep

    Studies consistently show that melatonin can help you fall asleep faster and sleep more effectively but not necessarily increase total sleep time.

    Melatonin has also been used effectively to shift sleep schedules, which can be beneficial for people with Delayed Sleep Phase Syndrome and jet lag .

    For REM sleep behavior disorder which is characterized by abnormal, often violent body movements during sleep scientists reported major benefits from taking melatonin. This included a marked decrease in muscle tension during REM cycles .

    Omega Restore users have frequently commented on similar body-calming effects, even in people without RBD. Partners often report their significant other tends to sleep with less movement and tossing around, as well as snore less and breathe more quietly.

    Who Should Take Melatonin

    Everyones needs are different so talking with a doctor is the best thing to do. That being said, there are numerous studies reporting sleep initiation efficacy and anti-proliferation properties. Its use in people with depression is surprising. One study showed that adding melatonin to someone who takes SSRIs does not positively impact the anti-depressive effects of these medications. Basically, if youre on depression medication, melatonin will help with initiating sleep, but doesnt improve depression symptoms. This does not mean that sleep wont help depression, it just means melatonin wont. Confusing yet?

    The hormone serotonin is produced during the day and this changes to melatonin when it gets dark outside. Peak levels of melatonin are produced before 3 a.m., when it sharply decreases before natural daylight returns.

    Research has found that taking melatonin in low doses is the most effective way to promote sleep if you are experiencing restlessness or insomnia. Recommended doses of melatonin are from 0.5 mg up to 3 mg, which are adequate to promote sleep or treat jet lag.

    When melatonin is used at higher doses, it tends to increase daytime sleepiness. Other side effects of too much melatonin can include reduced focus and concentration, feeling chilled and higher prolactin levels.

    If you find yourself taking higher doses of melatonin, you can decrease the dose by cutting your tablet in half or in quarters. Research indicates there are no side effects if you reduce the dose of melatonin you are taking.

    Health experts warn of risks with taking melatonin

    It depends on the specific person and whether theyd likely benefit.

    If you have poor CYP1A2 metabolism or kidney/liver impairment, high-dose melatonin should NOT be used unless theres an urgent medical need for it as it will likely accumulate rapidly and dysregulate your circadian rhythm .

    If you plan on consistently using high-dose melatonin or megadose melatonin know: exactly why youre using it the specific dose to take the specific duration for which youll use it the optimal administration timing and ideal administration frequency .

    At this time, there isnt strong evidence to formally endorse the usage of high-dose or megadose melatonin for any medical condition particularly over the long-term

    If youre dead-set on taking high-dose melatonin for the long-term, it would be smart to work with a medical doctor who supports your decision and get blood work done .

    What type of blood work should you get done?

    Id personally want a medical doctor to evaluate: CBC, lipids, hormones, vitamins/minerals, inflammation, and have an immunologist review my immune function .

    If high-dose melatonin is making you feel depressed, unproductive, or drowsy all day its probably not worth taking for a long-term.

    Can Promote Eye Health

    Melatonin is high in antioxidants that can help prevent cell damage and keep your eyes healthy.

    In fact, research suggests that melatonin could be beneficial in treating conditions like glaucoma and age-related macular degeneration .

    In a study in 100 people with AMD, supplementing with 3 mg of melatonin for 624 months helped protect the retina, delay age-related damage and preserve visual clarity .

    Additionally, a rat study found that melatonin decreased the severity and incidence of retinopathy an eye disease that affects the retina and can result in vision loss .

    However, research is limited and additional human studies are needed to determine the effects of long-term melatonin supplements on eye health.


    Melatonin is high in antioxidants and has been shown to treat eye conditions like age-related macular degeneration and retinopathy in human and animal studies.

    Melatonin has been shown to block the secretion of stomach acids. It also decreases the production of nitric oxide, a compound that relaxes your lower esophageal sphincter, allowing stomach acid to enter your esophagus .

    For this reason, some research suggests that melatonin may be used to treat heartburn and GERD.
