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
Confirmed evidence
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
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
We looked for these signals but could not settle them from public sources. A gap is not a strike.
USPTO returned multiple live supplement-class records for the exact brand wordmark: Twenty-First Century Laboratories, Inc., Twenty-First Century HealthCare, Inc., Twenty First Century Nutritional Products, Inc.. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.
Multi-ingredient blend with no single headline dose to check. The record did not retain a legible Supplement Facts panel from the source listing. A gap in the record, not a strike.
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 recall is not about the product on this page. Twenty-First Century Healthcare, Inc recalled a different product on May 7, 2021. FDA has since closed that case. The recalled item 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”. FDA recorded the reason as “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)”. Verify at FDA’s recall database.
We have not found a public label filing for this exact product. That is a gap in our records, not evidence that no filing exists.
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.
Exact-listing history records written-review counts from 211 on 2025-07-31 to 251 on 2026-08-24 (net +40). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
Open Food Facts resolves 740985275429 to "sentry" (brand not supplied), but that record lacks enough exact brand/product detail to confirm or contradict this listing.
What to ask and check
Ask the brand or seller
Can you send a clear photo of the full Supplement Facts panel?
It’s the one part of the label required to state what’s inside and how much. A seller who won’t show it before purchase is asking for trust the label would have earned.
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.
Where are the ingredients sourced, and where is the product manufactured?
“Made in USA” can describe only the final bottling step. Ask which country the actives came from and whether the facility is audited.
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
Scan the barcode on the package and confirm it reads 740985275429.
A mismatch between the barcode on the box and the one on the listing is worth pausing over — it can indicate a different variant, a repack, or a counterfeit.
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.
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.
What the listing promises — claim by claim
| Claim | Status | What we found |
|---|---|---|
| Origin claim “…100 TABLETS, TRUSTED FOR 34+ YEARS: Over three months of daily coverage, made in the USA from domestic and globally sourced ingredients in an FDA-registered facility and” | Claimed, not verifiable We looked for: customs records or label filings showing where ingredients were sourced and where it was made | “Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product. |
| Benefit claim “…COMPLETE SUPPORT FOR WOMEN OVER 50: A full-spectrum daily multivitamin built for women 50 and older, delivering the vitamins and minerals that help support heart, eye, b” | Not checked yet 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 checked yet — 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.
