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 August 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.
