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.
We did the comparison: the listing claims 1 mg of melatonin, and the listing-image panel shows 1 mg melatonin 1 tablet. Those amounts agree. This is internal consistency, not independent lab testing.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Melatonin | 1 mg | — | |
| Melatonin | 1 mg | — | |
| Melatonin | 2 mg | — |
FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a listed “proprietary blend” (legal, but a transparency yellow flag). A label stating no amount at all is non-compliant — a checkable red flag. This panel states amounts; any remaining comparison concerns the front-label framing.
vision:google/gemini-flash-1.5 Amounts are shown as listed panel data, not independently lab-tested contents.
Every check we ran
Confirmed evidence
These checks found support in the public record. They confirm specific facts, not the product as a whole.
label claims 1 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.
USPTO lists Zarbee's, Inc. (CORPORATION) in DELAWARE, USA for the exact brand wordmark. This identifies the USPTO mark owner or applicant; it does not by itself prove who manufactures or sells this product.
UPCitemdb resolves 858438005582 to "Zarbee's Kid's Sleep with Melatonin Chewables - Grape - 50ct: Dye-Free, Gluten-F" (Zarbee's) — consistent with this listing.
Written reviews grew from 1207 to 1209 across 2026-03-05 – 2026-07-16 with no single manufactured spike (largest 30-day gain ~3).
Documented concerns
These are documented contradictions or claims that need more evidence. They are separate from missing data.
The label visibly shows: “Melatonin appears more than once”. This is a specific printing or product-image inconsistency worth checking on the package.
Unresolved public record
We looked for these signals but could not settle them from public sources. A gap is not a strike.
The listing claims 1 mg; the photo-read Supplement Facts panel shows Melatonin at 1 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.
At 1.0 serving(s) a day to reach the low end of the studied range (0.5–5 mg), this product runs roughly $5 per month. A price observation, not a recommendation.
Published sources describe how melatonin have been studied. This is ingredient context only; the record does not establish that this product delivers the studied dose or outcome. Sources: NIH NCCIH — Melatonin, PubMed search: melatonin dose sleep onset.
Brand-level context only, not a finding about this product. Zarbee's Naturals Inc. recalled a different or not-exactly-bound product on 2015-09-21: “Some units of each lot may contain contaminants (elevated aerobic plate count) and do not meet acceptable visual appearance standards for the product.” (status: Terminated). The recalled product was: “Baby Omega 3 Dietary supplement (in liquid form), 15 ml and 14 ml in glass bottle with dropper dispenser.” — not necessarily the product on this page. Verify at FDA’s recall database.
This record does not currently hold an matched to this exact product public label filing for the exact product. That is a LookCloser coverage gap, not evidence that no filing exists.
The paid catalog links this exact item to a parent listing. Review counts on public product pages may be shared across sizes, flavors, or other variants, so the count history is listing context — not evidence that reviewers received or tested this exact variant.
Exact-listing history records written-review counts from 1,200 on 2026-02-19 to 1,209 on 2026-07-16 (net +9). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
What to ask and check
Ask the brand or seller
Which specific study supports this claim — and was it run on this exact formula?
Ask for the citation, how many people took part, the dose used, and whether the study tested this product or just one ingredient in it. Ingredient research is not product evidence.
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
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.
Scan the barcode on the package and confirm it reads 858438005582.
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.
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.
What the listing promises — claim by claim
| Claim | Status | What we found |
|---|---|---|
| Clinical-evidence claim “…d effective KIDS MELATONIN 1MG: Melatonin is clinically proven to work with your child’s natural sleep cycl…” | No evidence located We looked for: a named, citable clinical study of this product or formula | We found no named, citable study of this product or formula. The claim may rest on ingredient research rather than a trial of this product. |
| Benefit claim “…ELATONIN ZARBEE'S KIDS: These chewables help promote sleep on those nights when your little one h…” | 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 1 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). |
“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
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Melatonin | shaded = doses used in studies (0.5 mg–5 mg) · bar = this label | 1 mg — within 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.
