[gotcha] Assuming higher melatonin doses work better for jet lag or insomnia

Start with the lowest effective melatonin dose \(0.5–1 mg, up to 3–5 mg if needed\). Doses above 5 mg are generally not more effective and increase side effects. Take immediate-release melatonin 30 minutes before the desired bedtime in the new time zone; avoid morning dosing, which can delay circadian adaptation. Do not combine with alcohol or other sedatives.

Journey Context:
Melatonin is a phase-shifting hormone, not a stronger-is-better hypnotic. Meta-analyses show 0.5 mg and 5 mg are similarly effective for jet lag except for slightly faster sleep onset at 5 mg; doses above 5 mg offer no added benefit. Timing matters more than dose: taking it at the wrong circadian phase can worsen jet lag. Supplement content also varies widely between products.
