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.
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.
UPC independently corroborated
Open Food Facts resolves 693749003458 to "Iron Bisglycinate" (THORNE) — consistent with this listing.
No data yet: Label math could not be verified
What this means: the listing doesn't publish net weight, unit count, per-serving dose, so the dose claim can't be checked against physics from public data. That's neither a pass nor a strike — but it does mean you're taking the label on faith. Checkable products publish these numbers.
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.
Not found in NIH's DSLD label registry
The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.
Brand holds NSF/ANSI 173 certification (brand-level)
Thorne® appears in NSF’s certified-products registry with 10 certified product(s), but we couldn’t confirm this exact listing is among them. Closest listed product: “Thorne® Iron Bisglycinate (Canada)”. Certification covers contents and contaminants — not effectiveness.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Benefit claim “…ity, infrequent menstruation, and more Blood Support: Dietary iron is essential for the formation…” | Not assessed We looked for: whether the ingredient doses on the label match the doses used in published research | Ingredient-level evidence for this formula isn’t in our knowledge base yet. Recorded as not assessed — not as a negative. |
“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.
Verifiability profile — 3 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.
