Melatonin supplements can be naturally and synthetically made. Natural melatonin supplements are derived from the pineal glands of animals. This form is not necessarily vegetarian or cruelty-free, depending on the methods with which it was extracted. Natural melatonin may also carry viruses from the original animal.
Synthetic melatonin is manmade and does not involve the use of other animals. FDA regulations on melatonin are not particularly strict, so purity varies between manufacturers. A study that analyzed the melatonin content in 31 melatonin supplements purchased at pharmacies and grocery stores found that 70 percent of the supplements tested had more or less melatonin than what was advertised. One chewable melatonin tablet labeled as 1.5 milligrams actually contained almost 9 milligrams. It is important to understand which brands can be trusted. The pineal gland is an endocrine gland in your brain that synthesizes and secretes melatonin.
It is about the size of a pea and is the middle of your brain. Melatonin is a hormone that communicates information about environmental lighting to various parts of the body. It has the ability to regulate circadian rhythms and has important effects on reproductive function of many animals. The light-transducing ability of the pineal gland has led some to call the pineal the “third eye.” What is the Correct Dosage of Melatonin? There is not a singular, correct dosage of melatonin. How much you should take depends on many factors, including your body’s natural sensitivity levels, your overall health, your age, and what conditions in your life are prompting you to use it in the first place. The standard dose of melatonin for adults is between 2 tenths of a milligram and 5 milligrams. Take the supplement 60 minutes before you want to fall asleep. Some experts suggest buying pharmaceutical-grade melatonin online, as the dosage is likely to be more reliable. The table below lists common recommended melatonin dosages. Please remember to consult a physician before taking melatonin supplements for the first time. Use Recommended Dosage Jet lag 0.5 to 5 mg a few days before and after arrival Circadian rhythm disorders or insomnia 0.5 to 5 mg Delayed sleep phase syndrome 0.3 to 6 mg. If you use melatonin to help sleep, you can rest assured that even if you take way too much, it isn’t going to hurt you (although you’ll probably regret it the next day). It’s generally safe for short-term use, is non-habit-forming, and studies show that it does have some benefit as a sleep aid. But as with any medication or supplement, it’s best to take the smallest, effective dosepossible. From there, you can add onto your dosage as needed. This method will reduce the likelihood of side-effects. If you have a health condition or are taking prescription medications, you should talk to your doctor before you start taking it. Taking too much melatonin over a long period of time, can have damaging side effects. The first sign that your dosage was too high the night before is waking up with a melatonin hangover. You may feel groggy, sleepy, or have a headache, you may have taken too much melatonin. High levels of melatonin in the bloodstream may also be signaled by mild depression, low body temperature (hypothermia), irritability, and stomach cramps. Mild tremors and low blood pressure are less common but could be symptoms of too much melatonin.
Taking too much melatonin for too long can support a condition called rebound insomnia. As melatonin is a hormone that regulates your body clock, flooding it with one hormone can create an imbalance that may knock your entire body clock out of sync. One upside to using melatonin is that you’re not likely to become dependent on it, which can happen with prescription sleep aids. However, taking high doses for a long period of time can have the opposite of the desired effect — it will keep you up instead of helping you sleep. This happens because using too much melatonin for too long can desensitize the body’s neurological receptors, dulling the impact melatonin has on regulating sleep. If melatonin is not helping you sleep after 1-2 weeks of use, it’s likely never going to help you. Giving melatonin to children can be a controversial topic. In Europe, melatonin supplements are actually prescription-only medicine that is intended solely for adults. In the USA, the FDA has neither approved its use nor evaluated its safety in children. There are many reasons why a child or adolescent may experience sleep interruptions.
Emotional stressors such as a divorce, moving to a new town, attending a new school or moving up to a new grade can cause anxiety and disrupt sleep. Teens can experience a circadian rhythm disorder called “delayed sleep phase” in which the natural sleep and rise times are much later than normal (by three hours or more).
