MODERATE public verifiability

The short read
The product's Supplement Facts panel states 20mg of Melatonin per serving, which matches what's listed on the product page. While the brand claims third-party testing, the specific lab or certifier isn't public, so we can't verify that claim right now. You can check the listed ingredients and amounts against the Supplement Facts panel on the product's packaging.
Why this result?
We ran this product through public-record checks — label math, barcode registries, FDA recall lists, published lab tests. This banner sums up what those checks could and couldn’t confirm. Green means nothing public contradicted the label — not proof it works or is safe. Gray means the data to check simply isn’t public: a gap, not a verdict. We show the evidence; the conclusion is yours.
Confirmed evidence
What checked out04
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Confirmed
Taken the way the research studied it
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.
Every ingredient 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.
Barcode confirmed in an outside database
UPCitemdb resolves 631851987785 to "Melatonin 20mg Gummies for Adults - Maximum Strength Sleep Aid Gummies (120 Coun" (Just Nutrients) — consistent with this listing.
Documented concerns
What needs caution03
These are documented contradictions or claims that need more evidence. They are separate from missing data.
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.
Dose is higher than studies used
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.
“Lab tested” claimed, but no lab or report named
The listing claims third-party testing without naming any lab or certifier, so the claim can't be verified as stated.
Unresolved public record
What is still missing03
We looked for these signals but could not settle them from public sources. A gap is not a strike.
Reviews not analysed yet
Marketplace rating 4.6★ across 5,567 ratings. Authenticity not analysed: burst, purge and stockout patterns need price/review history.
Cost to reach a studied dose
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.
No label filed with NIH's public catalog
The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.
What to ask and check
What would settle the open questions
Why is this shown?
Everything we couldn’t verify is something a person can still ask about. Rather than leave gaps sitting as dead ends, we turn each one into a specific question — the exact document, citation, or number that would settle it — plus the things you can confirm yourself with the bottle in your hand.
Ask the brand or seller
1
Can you send the certificate of analysis (COA) for the lot number on my bottle?
A real COA names the testing laboratory, the test date, the lot it covers, and what was measured. “Third-party tested” with no document behind it is a marketing sentence.
2
Is this label filed with NIH’s Dietary Supplement Label Database (DSLD)?
Filing is voluntary, so absence proves nothing — but a filed label puts the full ingredient table on public record where anyone can read it.
Most brands and sellers publish a contact route. A clear answer adds evidence to the record; no answer leaves the question open.
Check for yourself — no one’s permission needed
1
Compare the panel on the bottle in your hand to the one shown in this record.
Ours was read from listing photos and can contain reading errors. The physical label is the source of truth — if they disagree, tell us and we’ll correct the record.
2
Scan the barcode on the package and confirm it reads 631851987785.
A mismatch between the barcode on the box and the one on the listing is worth pausing over — it can indicate a different variant, a repack, or a counterfeit.
3
Check the lot number and expiry on the bottle against any COA you’re given.
A certificate that doesn’t name your lot doesn’t describe what you’re holding.
These are the open questions on this specific record — not a warning about the product, and not a suggestion to buy or avoid it. Getting them answered is how you decide for yourself.
