Find the right melatonin dose for your age and sleep concern.
Melatonin is a hormone that regulates the sleep-wake cycle. Lower doses (0.5–1 mg) are often as effective as higher doses. It works best for circadian rhythm disorders and jet lag. Take 30–60 minutes before desired sleep time. It is not a sedative but a sleep signal. Children should use melatonin only under medical supervision.
