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
No data yet: Label math could not be verified
The retained listing evidence does not establish net weight, unit count, 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.
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.
FDA recall appears in this brand's history
Brand-level context only, not a finding about this product. Twenty-First Century Healthcare, Inc recalled a different or not-exactly-bound product on 2021-05-07: “A small quantity of bottles of Vitamin D3 125 mcg ((5000 IU) 100 ct. were mislabeled as Vitamin D3 25 mcg (1000 IU). Secondary labeling on the bottles (back label) is correctly labeled as Vitamin D3 125 mcg (5000 IU).” (status: Terminated). The recalled product was: “21st Century Vitamin D3 125 mcg (5000 IU) tablet, 100 count, UPC 7-40985-27431-6, 21st Century HealthCare, Inc., 2119 Wilson St., Tempe, AZ 85282” — not necessarily the product on this page. Verify at FDA’s recall database.
