Every ingredient 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.

This product can't be verified from public data Neither good nor bad — the checks below show what this listing publishes and what it withholds. Verifiable products publish more. Evidence availability only; this does not establish safety or effectiveness.
4 of 6 public trust signals found · 0 product-specific concerns
This Nature Made Vitamin B12 product lists 500 mcg of Vitamin B12 per tablet, and the Supplement Facts panel in the product images confirms this amount. This means the product's stated amount of Vitamin B12 matches what's presented on its label. We don't have data on the product's effectiveness, and the NIH Dietary Supplement Label Database has not yet listed this specific product. You can check that the product's UPC code, 031604010799, matches the one on the physical packaging.
Confirmed evidence
These checks found support in the public record. They confirm specific facts, not the product as a whole.
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
Open Food Facts resolves 031604010799 to "Nature Made Vitamin B12 500 mcg" () — consistent with this listing.
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.
We read the full Supplement Facts panel from the photos (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.
The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.
Brand-level context only, not a finding about this product. Pharmavite recalled a different or not-exactly-bound product on 2016-06-06: “Specific lots of Nature Made(R) Vitamin D tablets may exceed specifications for yeast/mold.” (status: Terminated). The recalled product was: “Nature Made(R) D3 1000IU, 125 count, UPC 0-31604-02793-3” — not necessarily the product on this page. Verify at FDA’s recall database.
Exact-listing history records written-review counts from 868 on 2026-01-23 to 885 on 2026-07-17 (net +17). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
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
Ask the brand or seller
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
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.
Scan the barcode on the package and confirm it reads 031604010799.
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.
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.
