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 10 separately ingredients with amounts and 2 combined blend totals. Ingredients inside a blend do not have separate amounts.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Vitamin B6 | 1.7mg | — | |
| Vitamin C | 32 mg | — | |
| Vitamin D3 | 15 mcg(600 IU) | — | |
| Magnesium | 200mg | — | |
| Relax-into Sleep Blend | 100mg | — | |
| Zinc | 1 mg | — | |
| Vitamin B6 | 3.4mg | — | |
| Vitamin C | 64 mg | — | |
| Vitamin D3 | 30 mcg(1200 IU) | — | |
| Magnesium | 400mg | — | |
| Relax-into Sleep Blend | 200mg | — | |
| Zinc | 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; the open question is whether those listed amounts are independently verified and how they compare with relevant research.
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.
USPTO lists Neviss LLC (LIMITED LIABILITY COMPANY) in CALIFORNIA, 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.
The label visibly shows: “Vitamin B6 appears more than once”; “Vitamin C appears more than once”; “Vitamin D3 appears more than once”; “Magnesium appears more than once”; “Relax-Into Sleep Blend appears more than once”; “Zinc 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.
Marketplace rating not shown★ — rating count unavailable. No exact-listing count history was available, so no review-pattern claim is made.
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, zinc 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.
What to ask and check
Ask the brand or seller
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.
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.
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 |
|---|---|---|
| Benefit claim “…Brain, Muscle, Melatonin Free Gummies,1Pack [Enhance Magnesium Absorption] The magnesium glycinat…” | 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 — see Related research below. 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
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Magnesium | shaded = doses used in studies (200 mg–420 mg) · bar = this label | 200 mg — within the studied range |
| Zinc | shaded = doses used in studies (8 mg–40 mg) · bar = this label | 1 mg — below 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.
Documented cautions
Statements from published sources about these ingredients — not advice about this product, and not a complete safety review. Anyone taking medication should talk to a pharmacist or clinician.
Verifiability profile — 2 of 6 public signals
What this listing gives the public to check. Publishing these signals doesn't prove quality — but withholding them means claims can only be taken on faith.

Related research & consistency
magnesium — NIH ODS — Magnesium fact sheet · PubMed search: magnesium glycinate supplementation · WebMD: magnesium · ClinicalTrials.gov — 3,206 registered studies
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.
zinc — NIH ODS — Zinc fact sheet · PubMed search: zinc supplementation trial · ClinicalTrials.gov — 1,598 registered studies
ℹ Use pattern in research: daily oral use; sustained high intakes can interfere with copper absorption — a documented interaction, not advice.
