Every ingredient amount is disclosed

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.
Panel, decoded
The 1 mg melatonin claim matches the panel
MARKETING1 mg — listing title
PANELMelatonin 1 mg — same amount
matches panelWe did the comparison: the listing claims 1 mg of melatonin, and the listing-image panel shows 1 mg melatonin serv size 1 ml. Those amounts agree. This is internal consistency, not independent lab testing.

| Melatonin | 1 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.

Every check we ran
Confirmed evidence
What checked out2
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Confirmed
Exact trademark owner identified
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.
Documented concerns
What needs caution0
These are documented contradictions or claims that need more evidence. They are separate from missing data.
No contradictions or product-specific cautions were found at this check depth.
Unresolved public record
What is still missing4
We looked for these signals but could not settle them from public sources. A gap is not a strike.
Review-count history: not available
Marketplace rating not shown★ — rating count unavailable. No exact-listing count history was available, so no review-pattern claim is made.
Multi-ingredient formula — panel read, serving weight unknown
We read the full Supplement Facts panel from the listing-image panel (below), but the label doesn’t state a serving weight, so the arithmetic can’t run. A gap in the label’s information, not evidence of a problem.
Research context is available for the listed ingredients
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.
FDA recall appears in this brand's history
This recall is not about the product on this page. Zarbee's Naturals Inc. recalled a different product on September 21, 2015. FDA has since closed that case. The recalled item was “Baby Omega 3 Dietary supplement (in liquid form), 15 ml and 14 ml in glass bottle with dropper dispenser.”. FDA recorded the reason as “Some units of each lot may contain contaminants (elevated aerobic plate count) and do not meet acceptable visual appearance standards for the product”. 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
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.
2
What is the product’s UPC or GTIN?
The barcode is how a product gets matched to outside records — certification registries, label databases, recall data. Without it, almost nothing can be cross-checked.
3
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
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
Why is this shown?
A listing’s promises are the reason people buy. Each one gets its own row: what was promised, what evidence would settle it, and what we could actually find. We never call a claim false — only whether proof proportionate to it exists on the public record.
| Claim | Status | What we found |
|---|---|---|
| Clinical-evidence claim “…Convenient size: The serving size contains 1mg of clinically studied melatonin to help promote peaceful sleep in kids.…” | 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 “…Gentle guidance: Each melatonin 1 mg serving of our liquid melatonin works naturally to help promote peaceful sleep in kids ages 3+ years*; natural berry flavor helps wi” | Partly supported We looked for: whether the ingredient doses on the label match the doses used in published research | Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed. |
“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?
An ingredient can be well-studied at one amount and barely studied at the amount in your bottle. This lines the label up against the doses researchers actually used. It answers ‘are these the same numbers?’ — never ‘should you take this?’
| 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.
