Melatonin is a hormone produced by the body that plays a central role in the sleep-wake cycle. It is released mainly in the evening and signals to the body that it is time to wind down.
Melatonin can help to shorten the time it takes to fall asleep, which can be particularly helpful for people who have difficulty falling asleep or after travelling across several time zones (jet lag). At the same time, it supports the regulation of the internal clock and helps to bring the natural day-night rhythm back into balance, for more regular sleep patterns.
Melatonin also promotes the overnight regeneration of body and mind, which can have a positive effect on performance and general wellbeing. As a natural and well-tolerated option, melatonin is also considered gentle support for healthy sleep, with no known habituation effect.
