“Melatonin works well for most sleep problems.”
A chronic-insomnia review found no significant improvement in the main adult non-comorbid insomnia outcomes. Melatonin can help some circadian-timing problems, so effectiveness depends on the problem and population rather than being a universal sleep remedy.
Melatonin may help jet lag or some delayed sleep-timing problems. It does not work well for every sleep problem; a review found no clear benefit on key sleep measures in adults with chronic insomnia without another associated condition.
Safety note: Daytime drowsiness and medication interactions are possible. Supplement contents may differ from labels, and long-term safety is uncertain. Store it out of children’s reach.
Talk to a healthcare professional if: Ask a clinician before giving melatonin to a child, during pregnancy or breastfeeding, or if you have epilepsy or take blood thinners or other medicines.
The cause of the sleep problem matters. Melatonin can be useful for selected timing problems, but persistent insomnia deserves assessment.
Before using it regularly, clarify the sleep problem and discuss whether melatonin and its timing are appropriate for you.

Use melatonin as a clock-resetter for jet lag or a shifted schedule - low dose, timed right - not as a nightly sleeping pill. A consistent schedule does more.
