Melatonin Supplements for Sleep

Melatonin, released by the pineal gland, regulates the circadian rhythm and induces sleep. It is a naturally created hormone that is responsible for helping us in falling asleep. It also maintains our sleep schedule, so a lack of melatonin can lead to sleep disorders, such as insomnia. Let’s look at melatonin supplements for sleep in more detail.
