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.
What the label discloses
The listing-image panel publishes an amount for each of its 25 declared rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Vitamin A | 1,050 mcg | — | |
| Vitamin C | 60 mg | — | |
| Vitamin D3 | 25 mcg | — | |
| Vitamin E | 13.5 mg | — | |
| Vitamin K | 25 mcg | — | |
| Thiamin | 1.5 mg | — | |
| Riboflavin | 1.7 mg | — | |
| Niacin | 20 mg | — | |
| Vitamin B6 | 2 mg | — | |
| Folate | 667 mcg DFE | — | |
| Vitamin B12 | 6 mcg | — | |
| Biotin | 30 mcg | — | |
| Pantothenic Acid | 10 mg | — | |
| Calcium | 200 mg | — | |
| Iron | 18 mg | — | |
| Phosphorus | 20 mg | — | |
| Iodine | 150 mcg | — | |
| Magnesium | 50 mg | — | |
| Zinc | 11 mg | — | |
| Selenium | 55 mcg | — | |
| Copper | 0.5 mg | — | |
| Manganese | 2.3 mg | — | |
| Chromium | 35 mcg | — | |
| Molybdenum | 45 mcg | — | |
| Chloride | 72 mg | — |
FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a declared “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 declared amounts are independently verified and how they compare with relevant research.
vision:google/gemini-flash-1.5 Amounts are shown as declared panel data, not independently lab-tested contents.
Every check we ran
Each ingredient’s 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.
No data yet: 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 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 the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Benefit claim “…or prevent any disease. B-Vitamins and iron support daily energy needs.* Antioxidants† support n…” | 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
Why is this shown?
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Magnesium | shaded = doses used in studies (200 mg–420 mg) · bar = this label | 50 mg — below the studied range |
| Zinc | shaded = doses used in studies (8 mg–40 mg) · bar = this label | 11 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.
Documented cautions
- magnesium — 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 — daily oral use; sustained high intakes can interfere with copper absorption — a documented interaction, not advice
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 — 1 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.
