- Quality
Passed
USP Verified. Independent testing confirms the label is accurate and free of contaminants.
- Honesty
Passed, with notes
Its "helps you fall asleep faster" claim is backed by low-certainty evidence of a small effect (about 7–10 minutes), so it's allowed but modest. No disease or proof claims.
- Effect size
Large
About 1 in 2 travellers helped beyond placebo (number needed to treat: 2), with bigger benefits the more time zones crossed.
- Certainty
Moderate
Downgraded one level: the trials are small, mostly from the 1980s–90s, and rely on travellers' own ratings.
- Dose fit
Fits
Trials used 0.5–5 mg.

Why melatonin might help
Your body's own darkness signal. It tells your brain that night has started, rather than knocking you out like a sleeping pill. That's why it helps most when your body clock is out of step, and least for ordinary trouble sleeping.

Who it works for
Adults flying across five or more time zones, especially eastward. Benefit is smaller on westward flights. Not for people with epilepsy or taking warfarin without medical advice.
Take near your new bedtime (10pm to midnight) at your destination for a few days. Taken early in the day, it can cause sleepiness and slow your adjustment.
