Melatonin
a timing cue, not a sleeping pill
Marketing intensity 85 of 100. Evidence strength 55 of 100. Verdict: Overhyped.
A circadian signal that helps you shift when you sleep. It is not a sedative, and most people take far too much.
Does Melatonin work? Benefits, claim by claim
Each claim is graded on the strength of human evidence — not how good the mechanism sounds, not how loud the marketing is.
-
Helps you fall asleep faster and shifts the body clock (jet lag, shift work)
ModerateIts best-supported use is re-timing sleep; a Cochrane review found it effective for jet lag.
-
Keeps you asleep / works like a sleeping pill
WeakIt doesn't sedate; it signals 'night.' The effect on sleep-onset latency is modest and it's poor for staying-asleep problems.

Melatonin side effects & safety
Moderate concern- Short-term use is generally safe; long-term data is limited.

Is Melatonin worth it?
Think of it as a clock cue, not a knockout. Try 0.5-1 mg a few hours before your target bedtime - not 10 mg as your head hits the pillow.
