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.
The listing-image panel publishes 6 separately ingredients with amounts and 1 combined blend total. Ingredients inside a blend do not have separate amounts.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Calories | 20 | — | |
| Total Carbohydrate | 4 g | — | |
| Total Sugars | 3 g | — | |
| Includes Added Sugars | 3 g | — | |
| Magnesium (as magnesium citrate) | 110 mg | — | |
| Melatonin | 2 mg | — | |
| Proprietary Blend | 30 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; the open question is whether those listed amounts are independently verified and how they compare with relevant research.
vision:claude-cli:subscription 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 2 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 The Procter & Gamble Company (CORPORATION) in OHIO, 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
These are documented contradictions or claims that need more evidence. They are separate from missing data.
Unresolved public record
We looked for these signals but could not settle them from public sources. A gap is not a strike.
Marketplace rating not shown★ — rating count unavailable. No exact-listing count history was available, so no review-pattern claim is made.
label states 110 mg/serving — about 26% of the adult daily reference (adult RDA 310–420 mg elemental; NIH sets 350 mg/day as the supplemental upper level for elemental magnesium). A single serving isn’t meant to supply a full day, so this is context, not a shortfall. Caveat: chelate labels (glycinate, citrate) often state compound mass, which reads ~5–7× higher than elemental magnesium — the Supplement Facts panel settles which is meant. Sources: NIH ODS — Magnesium fact sheet, PubMed search: magnesium glycinate supplementation.
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.
Published sources describe how magnesium, 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 ODS — Magnesium fact sheet, PubMed search: magnesium glycinate supplementation.
This recall is not about the product on this page. The Procter & Gamble Company recalled a different product on July 12, 2022. FDA has since closed that case. The recalled item was “Vicks ZzzQuil Liquid Melatonin Syrup Adult 8oz plastic bottle sold as single and twin pack”. FDA recorded the reason as “Acidified/Low Acid dietary supplement with no approved process”. Verify at FDA’s recall database.
We have not found a public label filing for this exact product. That is a gap in our records, not evidence that no filing exists.
Check digit passes; no third-party database record found yet. Coverage gaps are common — not a strike.
What to ask and check
Ask the brand or seller
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.
What is the amount of each ingredient inside the proprietary blend?
A blend total tells you nothing about whether any single ingredient reaches a dose used in research. Brands may decline — that answer is informative too.
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 323900045866.
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 |
|---|---|---|
| Speed-of-results claim “…MIXED BERRY FLAVORED: these fast-acting melatonin gummies^ are mixed berry flavored - you'll look forward to falling asleep, whether you're at home or traveling through ” | No evidence located We looked for: a study measuring the stated outcome over the stated time | We found no study of this product measuring the stated outcome over the stated timeframe. |
| Benefit claim “…Magnesium supports healthy muscle function.…” | 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 2 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 |
|---|---|---|
| Magnesium (as magnesium citrate) | shaded = doses used in studies (200 mg–420 mg) · bar = this label | 110 mg — below the studied range |
| Melatonin | shaded = doses used in studies (0.5 mg–5 mg) · bar = this label | 2 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.

ℹ Dosage: label states 110 mg/serving — about 26% of the adult daily reference (adult RDA 310–420 mg elemental; NIH sets 350 mg/day as the supplemental upper level for elemental magnesium). A single serving isn’t meant to supply a full day, so this is context, not a shortfall. Caveat: chelate labels (glycinate, citrate) often state compound mass, which reads ~5–7× higher than elemental magnesium — the Supplement Facts panel settles which is meant.
ℹ Use pattern in research: daily oral use; chelated forms (glycinate) are studied for absorption — note labels may state compound mass rather than elemental magnesium, which differs ~7-fold.
melatonin — NIH NCCIH — Melatonin · PubMed search: melatonin dose sleep onset · ClinicalTrials.gov — 1,068 registered studies
✓ Dosage: label claims 2 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).
ℹ Use pattern in research: taken before bed; timing matters more than size of dose in the research.
