Melatonin Syrup, Drops and Tablets
Melatonin is a hormone that regulates the sleep-wake cycle. It is primarily released by the pineal gland. As a supplement, it is often used for the short-term treatment of trouble sleeping including jet lag or shift work.
Blue light emitted by screens (TV, Computer, Phone, etc.) suppresses melatonin levels, making it more difficult to fall sleep.
