11. Melatonin Isn’t Regulated by the FDA
While many melatonin supplements are available over-the-counter in health food stores, pharmacies, and grocery stores, they are not regulated by the FDA. This means that they have not undergone the clinical trials and testing that regulated drugs must undergo to be deemed safe and effective. Additionally, supplements may include extra ingredients not listed on the label. Finally, since supplements do not undergo the clinical trials used to determine ideal dosing, the available dosages of melatonin may widely vary. If you choose to purchase melatonin supplements, look for products made by reputable companies.
10. Melatonin Doesn’t Work in All Cases
This supplement may not work in every situation in which sleep is desired. It may be helpful to use melatonin supplements when traveling to different time zones, if you have trouble falling asleep at night, or if you have a disorder resulting in problems with your sleep-wake cycle. It may not be helpful for treating general insomnia. Aid your body’s own production of melatonin by getting outside in the morning and afternoon to soak up some sunshine, and by dimming the lights in your home in the evening hours.
9. Melatonin Is Not Addictive
Unlike many prescription sleeping pills and sleeping aids, melatonin is not addictive. Most sleeping pills, called sedative-hypnotics, exert their effects by depressing the central nervous system. Over time, they can cause dependence, require increased dosages in order to achieve the same effect, and become habit-forming. Melatonin does not cause dependence and the effects do not appear to wear off with time.Related: 12 Ways Sleeping Too Much May Be Linked to Poor Health
