what does certainty mean?

Grade B / moderate: probably helps, and new studies are unlikely to reverse this — but could shrink the effect size.

What would change our mind

A registered RCT with adequate power in the target population would move the B grade; a null result would confirm the current position; a retraction of a keystone study would trigger an immediate re-review. We watch ClinicalTrials.gov for Melatonin registrations and flag readouts within 30 days.

Frequently asked

Is Melatonin worth the money?

"Worth it" depends on the outcome and grade. See the claims scoreboard: high hype at Grade C means expect less than the marketing implies.

Why is Melatonin suddenly everywhere?

The attention drivers block above lists specific dated triggers — podcasts, preprints, viral posts — that pulled attention forward of the evidence.

What would prove Melatonin actually works?

See "what would change our mind": registered trials in progress and the results that would move the grade.

Is Melatonin a scam?

Not usually — supplements exist and the compounds are real; the scam-adjacent claim is usually the specific benefit, not the substance. The grade tells you which benefit claims are honest.
