Melatonin: does it actually work, and is it safe?

Melatonin is the best-selling sleep supplement in the world — and one of the most misunderstood. It's a timing signal, not a sedative.

What it's actually good for

Melatonin shines at shifting your body clock: jet lag, shift work, and delayed sleep phase (the "night owl" who can't fall asleep until 3 AM). For garden-variety insomnia, the evidence is modest — it may help you fall asleep a little faster, but it's not a knockout pill.

Dosing — less is more

• Smaller doses (0.5–1 mg) often work as well as big ones. The common 3–10 mg tablets are frequently more than needed.
• Timing matters more than dose. For body-clock shifting, taking it a few hours before bed can be the point — ask a professional how to time it.

Safety & the PH reality

• Short-term use is generally considered safe for adults; grogginess and vivid dreams are the usual side effects.
• In the Philippines it's sold as an OTC food supplement (Nutrabliss, Sleepwell and others) — supplement quality and actual content can vary between brands.
• Talk to a doctor before using it with other medications, in pregnancy, or for children.
