Melatonin is a vital hormone produced in humans and animals. It is responsible for sleep and wakefulness. In a way, melatonin regulates our internal rhythm: when we wake up, what time we go to sleep, and when we feel tired. Having too little melatonin can negatively influence our health, but having too much isn’t desirable either. If you’re planning on taking melatonin supplements, read these ten essential facts about melatonin first.

1. The Body Produces Melatonin Naturally

Even though melatonin can be readily purchased at pharmacies, it is also naturally produced by the body. Just like any other hormone, the body produces a certain amount of melatonin, ideally just the right amount for correct bodily function. Some people refer to melatonin as the “Dracula hormone” due to its tendency to make you feel sleepy. Melatonin is produced by a small gland in the brain called the pineal gland. If melatonin production becomes impaired, you may find it difficult to fall asleep. That’s where melatonin supplements can come in handy, allowing you to get a better night’s sleep.
