Melatonin is hormone.
Melatonin is a hormone generated by a gland in the brain that helps regulate your body's circadian rhythm and 24-hour sleep-wake cycle.
Your body naturally produces melatonin on its own.
Melatonin is a hormone naturally generated by your body to help you fall asleep each night. It aids in immune function and impacts your circadian rhythm.

Melatonin supplements can contain up to 20x the amount your body naturally produces.
The amount of melatonin in over-the-counter supplements far exceeds what your body naturally produces.
Too little or too much melatonin means supplementing can actually have the opposite effect and keep you awake.

Over-the-counter melatonin has been shown to contain as little as 15% and as much as 155% of the advertised amount.
