Melatonin shifts your body clock, which is why it is the go-to for jet lag and a delayed sleep schedule. Below, the melatonin products people use ranked by real cost per dose (to the commonly-studied 3 mg dose). A value comparison, not medical advice.
Updated September 2026
What the evidence actually shows
Reasonably well-established for shifting sleep TIMING (jet lag, delayed sleep phase). Lower doses (0.5–3 mg) work as well as higher ones, and it is a timing signal, not a sedative.
Commonly used: 0.5–3 mg, 30–60 min before target bedtime.
How this list is built: these are melatonin products ranked by real cost per dose across our whole melatonin catalogue — not filtered or re-ordered by sleep. We don’t hold per-product evidence for a specific use, so we don’t pretend to rank for one. Products whose own label says they are for something else are left out.
