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.
The 500 mg quercetin claim matches the panel
We did the comparison: the listing claims 500 mg of quercetin, and the listing-image panel shows 500 mg quercetin 2 capsules. Those amounts agree. This is internal consistency, not independent lab testing.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Quercetin | 500 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; any remaining comparison concerns the front-label framing.
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.
Exact trademark owner identified
USPTO lists Pure Encapsulations, Inc. (['CORPORATION', 'SOCIÉTÉ ANONYME (SA)']) in ['DELAWARE, USA', 'SWITZERLAND'] 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.
UPC independently corroborated
UPCitemdb resolves 766298002309 to "Pure Encapsulations Quercetin - 500 mg - Immune Support Cellular Health & Heart" (Pure Encapsulations) — consistent with this listing.
No data yet: Label math could not be verified
The retained listing evidence does not establish net weight, per-serving dose, servings per container, so the dose claim cannot yet be checked against serving arithmetic. This is a neutral evidence gap, not a pass or strike.
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.
FDA recall appears in this brand's history
Brand-level context only, not a finding about this product. Pure Encapsulations, Inc. recalled a different or not-exactly-bound product on 2017-11-17: “Product contains undeclared sulfites.” (status: Terminated). The recalled product was: “Pure Encapsulations Systemic Enzyme Complex DIETARY SUPPLEMENT 180 CAPSULES UPC: 7 66298 00862 2” — not necessarily the product on this page. Verify at FDA’s recall database.
180-day review-count history is on file
Exact-listing history records written-review counts from 72 on 2026-01-22 to 92 on 2026-07-07 (net +20). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
This item belongs to a catalog variation family
The paid catalog links this exact item to a parent listing. Review counts on public product pages may be shared across sizes, flavors, or other variants, so the count history is listing context — not evidence that reviewers received or tested this exact variant.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Benefit claim “…e Encapsulations Quercetin - 500 mg - Immune Support, Cellular Health & Heart Health* - Antioxida…” | 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 — 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.
