MODERATE public verifiability
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.

The short read
The Supplement Facts panel shows 2000 IU (50 mcg) of Vitamin D3, which matches what's listed. This means the amount of Vitamin D3 per serving is documented, but it doesn't tell us how well the body might absorb or use it. This record doesn't yet include details about the product's manufacturing practices or review authenticity. You can check if the UPC on your bottle, 031604026745, matches the information on the bottle's label.
Why this result?
We ran this product through public-record checks — label math, barcode registries, FDA recall lists, published lab tests. This banner sums up what those checks could and couldn’t confirm. Green means nothing public contradicted the label — not proof it works or is safe. Gray means the data to check simply isn’t public: a gap, not a verdict. We show the evidence; the conclusion is yours.
Confirmed evidence
What checked out03
These checks found support in the public record. They confirm specific facts, not the product as a whole.
✓
Taken the way the research studied it
Nothing in this listing contradicts how these ingredients were studied (magnesium). For example, magnesium: daily oral use; chelated forms (glycinate) are studied for absorption — note labels may state compound mass rather than elemental magnesium, which differs ~7-fold. Sources: NIH ODS — Magnesium fact sheet, PubMed search: magnesium glycinate supplementation.
Confirmed
✓
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.
Confirmed
✓
Barcode confirmed in an outside database
Open Food Facts resolves 031604026745 to "D3 vitamin" (Nature Made) — consistent with this listing.

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 missing04
We looked for these signals but could not settle them from public sources. A gap is not a strike.
…
The listing doesn't publish enough to check the math
What this means: the listing doesn't publish net weight, per-serving dose, servings per container, so the dose claim can't be checked against physics from public data. That's neither a pass nor a strike — but it does mean you're taking the label on faith. Checkable products publish these numbers.
No data

No label filed with NIH's public catalog
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 1,375 on 2026-02-26 to 1,384 on 2026-04-10 (net +9). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
No data
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
Which specific study supports this claim — and was it run on this exact formula?
Ask for the citation, how many people took part, the dose used, and whether the study tested this product or just one ingredient in it. Ingredient research is not product evidence.
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
Scan the barcode on the package and confirm it reads 031604026745.
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.
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.
