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
Each ingredient’s 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.
UPC independently corroborated
Open Food Facts resolves 031604010799 to "Nature Made Vitamin B12 500 mcg" () — consistent with this listing.
Multi-ingredient formula — panel read, serving weight unknown
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.
Not found in NIH's DSLD label registry
The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.
FDA recall appears in this brand's history
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.
180-day review-count history is on file
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.
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 the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Benefit claim “…cg, Dietary Supplement for Energy Metabolism Support, B12 Vitamins 500 mcg, 200 Tablets, 200 Day…” | Not assessed 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 assessed — 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.
Verifiability profile — 4 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.

Where it sells
| Seller | Price |
|---|---|
| Brand store (naturemade.com) ↗ | $10.69 same product on the brand store — bottle count or subscription plan may differ from the retailer listing |
Brand store naturemade.com: 173 supplement products (+22 merch items) — for comparison, single-focus brands typically carry 5–30 products; very broad catalogs are common among companies that rebrand ready-made formulas — a pattern note, not a verdict.
