What does melatonin actually do?
Melatonin is a hormone naturally produced by the body that helps regulate circadian rhythm, or your internal sleep-wake clock. Its primary role is to signal that nighttime has arrived and help prepare the body for sleep, rather than simply “knocking you out.”
Is more melatonin better?
Not necessarily. Melatonin is a biological signal, so taking more does not always mean better sleep. Lower doses may be enough to support healthy sleep timing and sleep onset, while larger amounts can be unnecessary for some people and may contribute to next-day grogginess.
Does melatonin help you fall asleep or stay asleep?
Melatonin is best known for supporting sleep onset and proper sleep timing. It helps reinforce the body’s natural nighttime signal, while other nutrients and sleep-supporting compounds may be better suited for relaxation, sleep quality, and deeper, more restorative sleep.
When is melatonin most useful?
Melatonin may be especially helpful when your natural sleep schedule is disrupted or when you have difficulty feeling sleepy at the appropriate time. By supporting circadian timing, it can help your body recognize when it is time to wind down and begin the sleep process.
