Is 10 mg of melatonin too much?

Because it does not have to be prescribed, and since it is in the public domain, few doctors care to publicize its advantages

sounds like someone has an axe to grind

I went through the Ambien roller-coaster while combatting chronic insomnia last year. I asked three different doctors about melatonin, and they all recommended me not taking it, but sticking with them on the Ambien train. A fourth doctor actually recommended melatonin, and showed me a couple of websites which cited most of the research and results, and when I began taking it, it was like night and day. After less than three days, my chronic insomnia was under control. It still took me a couple months to recover from the effects of chronic insomnia , but Im still taking just .3 milligrams and am doing fine. Mugaliens 14:30, 22 July 2006

How Much Melatonin Is Too Much Can You Overdose On Melatonin

Taking too much melatonin can disrupt your circadian rhythm and cause unwanted side effects so yes, you can technically overdose on melatonin.“Signs of melatonin overdose may include but are not limited to excessive sleepiness, dizziness, upset stomach, diarrhea, lethargy, low blood pressure and confusion,” Dr. Rishi says. Officials at the American Academy of Sleep Medicine also highlight chronic headaches, high blood pressure, vomiting or nausea, as well as increased hair loss as potential symptoms of a melatonin overdose.

It’s important to note that melatonin is marketed as a dietary supplement in the U.S. andis not regulated by the U.S. Food and Drug Administration which means there are no official safety guidelines on dosage, though the best products abide by the “USP Verified” program that establishes production standards guided by the U.S. Pharmacopeial Convention.

However, Dr. Rishi advises that adults should not take more than 5mg a night without talking to their doctor or medical provider. Any dosage higher than this threshold is more likely to trigger immediate side effects including headache and dizziness in some individuals, as highlighted in materials published by the Mayo Clinic.

If you believe you’ve taken too much melatonin, you should contact Poison Control at 1-800-222-1222.

How Else Can You Improve Your Sleep Quality

“Melatonin works synergistically with other practices,” says Dr. Dow. “You’ll get the best results by combining a melatonin supplement with simple sleep hygiene strategies like keeping a consistent bedtime, exposing yourself to natural light first thing in the morning, and keeping the bedroom very dark and cool.” That includes avoiding blue light, so no scrolling through your phone or staring at the clock.

Most importantly, you’ll want to seek medical guidance to find the root of your insomnia. “As a sleep clinician, I first ask why is this person not sleeping?” Dr. Singh says. “That’s the fundamental thing.” Mental health and quality sleep go hand-in-hand, and melatonin alone can’t fix those kinds of issuesnor can it cure chronic, long-term insomnia. So, if you think you need to take melatonin everyday, don’t. Instead, talk to your doctor about more effective strategies and treatments for long-term relief.

What Is The Right Dosage Of Melatonin: How Much Is Too Much

Knowing how much melatonin to take is tricky, especially since some brands may recommend a dosage thats more than your body actually needs.

As you shop around, youll find that some melatonin supplements contain as much as 5 to 10 milligrams per serving.

Generally speaking, most people produce enough melatonin to sleep well. If you need a little extra to reset your sleep cycle, you probably dont need more than 3 mg. Some people sleep better with as little as 0.3 to 0.5 mg.

Melatonin needs vary from person to person. Since melatonin can have many effects on the body, like all drugs, it should be taken at the lowest dose possible, warns Dr. Jacobowitz.

With that being said, start with a low amount. If you still have problems sleeping, gradually step up your dose until you find an amount that improves sleep without causing side effects.

Less is more with melatonin to avoid sleep inertia. This is a common problem with some sleeping pills. Some people complain of a hungover or groggy feeling in the mornings due to remnants of the sleep aid remaining in their bloodstream.

Melatonin is also safe for children. And like adults, some children dont need a lot of the supplement to sleep better.

Again, start your child at a lower dose, and then gradually increase the amount of melatonin as needed. Talk to your doctor for advice on appropriate dosages.

Melatonin Dose For Children

Broadly speaking, Dr. Goldman doesnt have recommendations for children when using melatonin.

    Synthesis And Physiologic Role In Humans

    Melatonin is an indole hormone, widely distributed in both plant and animal sources, such as human milk, bananas, beets, cucumbers, and tomatoes. Chemically, melatonin is N-acetyl-5-methoxytryptamine, a derivative of serotonin, which in turn is derived from tryptophan. Serotonin is first acetylated by N-acetyltransferase and then methylated by hydroxyindole orthomethyltransferase to form melatonin. Melatonin synthesis depends on intact beta-adrenergic receptor function. Norepinephrine activates the N-acetyltransferase and beta-receptor blockers depress melatonin secretion.

    The enzymes of melatonin synthesis are activated and depressed, respectively, by darkness and light. Release of melatonin follows a circadian rhythm generated by the suprachiasmatic nuclei in response to daylight alterations.

    Through melatonin release, the pineal gland maintains the internal clock governing the natural rhythms of body function. This apparent clock-setting property of melatonin has led to the suggestion that it is a chronobiotic substance that alters and potentially normalizes biological rhythms and adjusts the timing of other critical processes and biomolecules that, in turn, exert numerous peripheral actions.

    Understanding Melatonin: The Effect of Timing

    “Most individuals will do fine on a two to two-and-a-half milligram dose,” says Dr. Chelsie Rohrscheib, Ph.D., neuroscientist and Head Sleep Specialist at Wesper. “Using more than five milligrams of melatonin per night isn’t recommended unless you’re working closely with your doctor.” Typically, 10 milligram options aren’t available over the counter and would only be recommended for those who suffer from blindness and non-24 hour sleep-wake disorder, explains Dr. Durmer. “Too much melatonin can actually disrupt the circadian rhythm and make sleep more difficult,” Dr. Rohrscheib adds. When you first “start low and go slow,” Dr. Rohrscheib recommends beginning with a half or one milligram one hour before bedtime, then “increasing in small increments until you find a dose that works for you.”

    What Is The Best Time To Take Melatonin

    Melatonin is not a sleep aid its a sleep regulator. What this means is that melatonin signals to your body that its time to sleep, but it does not sedate you, like typical sleep medicines.

    Because of this distinction, its important to pay attention to timing when taking melatonin.

    The best time to take melatonin may in part depend on the situation. For instance, scientists are currently exploring the optimal time to take melatonin for people working overnight shifts. For improving sleep quality at a regular bedtime, however, several reviews recommend taking melatonin between 30 to 60 minutes before sleeping .
