Melatonin For Older Adults
The amount of melatonin your body produces decreases with age. Because of this, melatonin supplements may be helpful for older adults who are having trouble falling asleep.
Researchers are still looking into the optimal melatonin dosage for older adults. One 2016 review of sleep aids for older adults suggests a dosage of 1 to 2 mg of immediate-release melatonin 1 hour before bedtime.

Your Lifestyle Habits Can Impact Your Natural Melatonin Production
There are a few habits you should consider changing if you want to help your body produce more melatonin.”We live in a time where people are staying up later working, watching television, or scrolling on their phones,”Dr. Judy Hinojosa, N.M.D lead physician and owner of Vitality Natural Health Care, tells Bustle. “Weâre also eating later in the day because weâre staying up late â both of these factors can adversely affect our sleep.”Having electronic devices next to your bed, watching TV, drinking alcohol, snacking, and exercising too intensely right before bed, can also be disruptive to your sleep. So if you are having trouble sleeping, try changing these habits first before you turn to sleep aids.
How Much Melatonin Should You Take And When
Even though bioavailability of over-the-counter melatonin is quite low , a dose of between 1-5 milligrams, consumed approximately 20 minutes before bedtime, will raise blood levels by 10-100 times the amount you would otherwise achieve while sleeping. The effects will last for about 4-8 hours.
Women appear to have greater bioavailability and a faster return to baseline levels than men. Experiment with your dosing of melatonin so that you take enough to get the sleep you want but avoid the hangover effect that can happen when you take too much. Start with 1 milligram of melatonin, then increase your dose by 1 milligram per evening until you find the dose that’s best for you.

Finding the sleep aid that works for you may take time. Ensuring that you are engaging in healthy sleep hygiene practices may also help you get better sleep.

Adverse Effects Of Melatonin Intake: Overview
Consumption of food supplements that contain melatonin or mainly contain melatonin has shown adverse effects in numerous studies. The most frequently reported side effects include; headaches, dizziness, drowsiness, tremors, migraine, nausea, vomiting, abdominal pain, nightmares, vivid dreams, and irritability. There were even cases of supplement abuse for suicide attempts through melatonin overdose.
The reason for such adverse effects was traced to an incorrect presentation of the amount of melatonin a bottle of supplements truly contains. Investigation shows that melatonin supplement bottles can have;4 times more melatonin than indicated. This can affect ones health significantly, because of the higher the dose, the serious and more frequent side effects.
However, this is not the only reason side effects occur. Sometimes, doctors do NOT prescribe a suitable dosage, or the patients decide to dose themselves as they want. Some people even tend to drink alcohol with melatonin, hoping to emphasize the sedative effects. But, they just cause even more serious side effects.

Melatonin May Improve Your Insomnia But Not As Much As You’d Think
According to a 2016 study published in the Journal of Family Medicine and Primary Care, approximately one-third of American adults may suffer from chronic insomnia . Insomnia defined as difficulty falling or staying asleep can have many causes. These include stress, depression, anxiety, use of certain medications or substances, and disruptive elements in your sleeping environment like light and noise. People with insomnia often don’t get enough high-quality sleep, leading to daytime sleepiness, mood changes, and difficulty concentrating .
Since melatonin is the hormone that cues the body that it’s time to sleep, it makes sense that taking supplemental melatonin would swiftly whisk insomniacs off to dreamland. According to WebMD, however, the supplement’s effect on both sleep latency and total sleep time are minimal. Popping a melatonin pill before bed appears to shave only an average of seven to 12 minutes off the time insomniacs spend tossing and turning. And, while some people may report feeling better rested after taking melatonin, the objective data doesn’t always back up their subjective conclusions.;;
How Much Melatonin Should You Take
The United States Food and Drug Administration classifies melatonin as a dietary supplement, similar to vitamins and minerals. This classification means that melatonin is not regulated in the same way prescription or over-the-counter medications are. Therefore, there are no safe dosage guidelines for melatonin, making it difficult to determine the right amount to take.
Additionally, melatonin affects each person differently. A low dose of melatonin may cause extreme sleepiness in one person and have no effect on another. There is also conflicting evidence on whether or not this supplement is safe for pregnant women or young children.
Melatonin supplements are available in a wide range of doses. Doses can be as low as 0.3 milligrams to as high as 10 milligrams. Additionally, melatonin supplements are available in a variety of formulations. Examples include oral capsules or tablets, sublingual liquid or sprays, topical creams or drops, and intravenous preparations. Moreover, melatonin is available in different release forms such as immediate, extended, and timed release. The duration and elimination of melatonin depends on all of these factors as well as individual demographics and metabolism, says Dr. David Gao of Memorial Sloan Kettering Cancer Center.
Due to these risks, we suggest avoiding melatonin use altogether and, instead, try to increase your melatonin levels naturally through diet, exercise, and light exposure.

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.
