The short read
The listing states this product contains 5 mg of Melatonin per gummy, which matches what's written on the Supplement Facts panel. However, the barcode on this listing is linked to a different product, creating a discrepancy. You can check the barcode on your product's packaging against the one shown in the listing to see if they match. The NIH Dietary Supplement Label Database currently has no record of this product.
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 out05
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Confirmed
Listing claim matches the label panel
The listing claims 5 mg; the photo-read Supplement Facts panel shows Melatonin at 5 mg per serving. The two independent statements agree.
Melatonin dose matches the amounts used in studies
label claims 5 mg/serving — within 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.
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.
Documented concerns
What needs caution01
These are documented contradictions or claims that need more evidence. They are separate from missing data.
UPC resolves to a different product
Open Food Facts lists 047469073329 as "Melatonin 5mg" () — which does not match this listing. Recorded as a discrepancy to explain, not proof of fraud.
Unresolved public record
What is still missing04
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 4.7★ across 17,563 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 $4 per month. A price observation, not a recommendation.
No label filed with NIH's public catalog
The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.
This brand had a recall in the past (now closed)
Brand-level history, not a finding about this product. Natrol, LLC recalled a product on 2021-04-08: “One lot of ALA 300 mg Cap-50 were labeled at Melatonin 3 mg Tab-60.” (status: Terminated, case closed). The recalled product was: “Natrol Melatonin 3 mg, Tab 60 White bottle with purple flip-top cap. Fall asleep faster, Stay asleep longer, 100$ Drug Free 1 Tablet 20 minutes before bedtime. Manufactured by N” — not necessarily the product on this page. Verify at FDA’s recall database.
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
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 047469073329.
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.
