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 listing amount and panel row need explanation
We compared the listing claim (1 g) with the panel row (300 mg total omega-3 fatty acids). They do not match within the report tolerance; the source label or serving basis needs checking.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Calories | 10 | — | |
| Total Fat | 1 g | — | |
| Cholesterol | 5 mg | — | |
| Fish Oil Concentrate | 1,000 mg | — | |
| total Omega-3 Fatty Acids | 300 mg | — | |
| EPA (Eicosapentaenoic Acid) | — | — | |
| DHA (Docosahexaenoic Acid) | — | — |
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
Panel carries documented template or translation artifacts
The panel carries these quoted observations: “Calories has no unit”. US-market labels are produced under cGMP controls; these are template or translation artifacts worth checking, not proof that the label is fabricated or that the product is unsafe.
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 omega-3 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 — Omega-3 Fatty Acids fact sheet, PubMed dose-response trial.
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.
Brand holds NSF/ANSI 173 certification (brand-level)
21st Century HealthCare, Inc. appears in NSF’s certified-products registry with 0 certified product(s), but we couldn’t confirm this exact listing is among them. Certification covers contents and contaminants — not effectiveness.
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.
This label vs. the doses studied
Why is this shown?
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Fish Oil Concentrate | shaded = doses used in studies (300 mg–1.8 g) · bar = this label | 1 g — 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.
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.
