How to read this report
What this is. We compare what a listing claims against what public records show — label arithmetic, barcode registries, NIH’s label catalog, FDA enforcement data, certification registries, and published research. Every statement below traces to one of those.
What the states mean. Confirmed = an outside source agrees. Contradicted = an outside source disagrees. Caution = something needs explaining. No data = we looked and found nothing — a gap, not a strike.
What it is not. A clean record is not an endorsement and never proof a product works. A thin record is not an accusation. We publish evidence and gaps; the conclusion is yours. Nothing here is medical advice.
Something wrong? Every figure is meant to be checkable — sources are named and linked. Send a correction and we’ll fix the record.
Every check we ran
Listing claim doesn't match the Supplement Facts panel
The listing claims 10 mg, but the photo-read Supplement Facts panel shows Melatonin at 20 mg per serving — a discrepancy to explain, not proof of fraud.
Melatonin dose is above the studied range
label claims 10 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 from their labels). Sources: NIH NCCIH — Melatonin, PubMed search: melatonin dose sleep onset.
Testing claimed — but not publicly substantiated
The listing claims third-party testing without naming any lab or certifier, so the claim can't be verified as stated.
Label math is physically consistent
Claimed melatonin 10.0 mg is 0% of the ≈4,536 mg serving (listing net weight ÷ servings) — within physical limits.
Intake method matches the research
Nothing in this listing contradicts how these ingredients were studied (melatonin). For example, melatonin: taken before bed; timing matters more than size of dose in the research. Sources: NIH NCCIH — Melatonin, PubMed search: melatonin dose sleep onset.
Each ingredient’s amount is disclosed
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
UPC independently corroborated
UPCitemdb resolves 631851987785 to "Melatonin 20mg Gummies for Adults - Maximum Strength Sleep Aid Gummies (120 Coun" (Just Nutrients) — consistent with this listing.
No data yet: Review authenticity: not yet analyzed
Marketplace rating 4.6★ across 5,567 ratings. Authenticity not analysed: burst, purge and stockout patterns need price/review history.
Reaching a studied dose costs about $12/month
At 1.0 serving(s) a day to reach the low end of the studied range (0.5–5 mg), this product runs roughly $12 per month. A price observation, not a recommendation.
Not found in NIH's DSLD label registry
The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Quality-testing claim “…uten Dairy-Free c GMP FACILITY PACKED IN USA LAB TESTED NON GMO INGREDIENTS” | Claimed, not verifiable We looked for: a named laboratory, a certificate of analysis, or a certification-registry entry | No named laboratory, no certificate of analysis, and no certification-registry entry matching this product was located. |
| Manufacturing claim “…a 2-month supply. Bottled in the USA in our GMP-compliant facility and tested for potency an…” | Claimed, not verifiable We looked for: the facility registration or certificate behind the claim | Facility-level claims can be accurate and still say nothing about this product’s contents. No registration document was located. |
| Benefit claim “…Gummies (120 Count) - Maximum Strength Sleep Support for Adults with 10mg of Melatonin Per Gummy…” | Partly supported We looked for: whether the ingredient doses on the label match the doses used in published research | Ingredient evidence exists; on dose: label claims 10 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 from their labels). |
“No evidence located” does not mean a claim is false — it means the seller has not put evidence proportionate to the claim on the public record, and we could not find any. Absence of proof is not proof of absence.
This label vs. the doses studied
Why is this shown?
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Melatonin | shaded = doses used in studies (0.5 mg–5 mg) · bar = this label | 20 mg — above the studied range |
Matching a studied dose does not mean the product works, and missing it does not mean it fails — it shows whether the label and the research are talking about the same amounts. Not a recommendation to take any amount.
