Does the marketing hold up?
The label says 11 g of melatonin in 4 gummies — but not what those 4 gummies weigh. That weight is the one number that would let anyone check the amount on the front. We did not weigh it ourselves, so this is an open question, not a problem we found.

Background reading
What the research says about these amounts
Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.
The panel lists 2 mg of melatonin per serving. Studies we found used 0.5 mg–5 mg a day, so this sits inside that range.

Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
