Does the marketing hold up?
Melatonin dose is above the studied range. label claims 20 mg/serving — above the range commonly used in research (sleep trials commonly use 0.5–5 mg; higher doses are not shown to work better and gummy products have repeatedly been found to differ…
“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

No named laboratory or lot-specific certificate was found for this exact product. A related brand page repeats a testing claim but names no issuer; its UPC is not published. NSF, IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur.

Dose and research context
The label amount is shown beside the range used in the linked ingredient studies.
Melatonin
20 mg per serving — above the 0.5–5 mg/day used in the linked studies.
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 20 mg of melatonin per serving. Studies we found used 0.5 mg–5 mg a day, so this sits above that range.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
