FDA recall appears in this brand's history

An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.

Confirmed evidence

What checked out00

These checks found support in the public record. They confirm specific facts, not the product as a whole.

Nothing could be independently confirmed from the available record.

Documented concerns

What needs caution00

These are documented contradictions or claims that need more evidence. They are separate from missing data.

No contradictions or product-specific cautions were found at this check depth.

Unresolved public record

What is still missing06

We looked for these signals but could not settle them from public sources. A gap is not a strike.

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.

No data

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.

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.

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.

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 to ask and check

What would settle the open questions

Why is this shown?
Everything we couldn’t verify is something a person can still ask about. Rather than leave gaps sitting as dead ends, we turn each one into a specific question — the exact document, citation, or number that would settle it — plus the things you can confirm yourself with the bottle in your hand.

Ask the brand or seller

1

What is the product’s UPC or GTIN?

The barcode is how a product gets matched to outside records — certification registries, label databases, recall data. Without it, almost nothing can be cross-checked.

2

Is this label filed with NIH’s Dietary Supplement Label Database (DSLD)?

Filing is voluntary, so absence proves nothing — but a filed label puts the full ingredient table on public record where anyone can read it.

Most brands and sellers publish a contact route. A clear answer adds evidence to the record; no answer leaves the question open.

Check for yourself — no one’s permission needed

1

Compare the panel on the bottle in your hand to the one shown in this record.

Ours was read from listing photos and can contain reading errors. The physical label is the source of truth — if they disagree, tell us and we’ll correct the record.

2

Look the product up yourself in NSF’s certified-products registry.

Search “21st Century HealthCare, Inc.” at info.nsf.org — certification covers contents and contaminants, not effectiveness.

3

Check the lot number and expiry on the bottle against any COA you’re given.

A certificate that doesn’t name your lot doesn’t describe what you’re holding.

These are the open questions on this specific record — not a warning about the product, and not a suggestion to buy or avoid it. Getting them answered is how you decide for yourself.
