The listing-image panel publishes an amount for each of its 4 declared rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Vitamin D3 (as Cholecalciferol) | 5 mcg (200 IU) | — | |
| Calcium (as Calcium Carbonate) | 333 mg | — | |
| Magnesium (as Magnesium Oxide) | 133 mg | — | |
| Zinc (as Zinc Sulfate) | 5 mg | — |
FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a declared “proprietary blend” (legal, but a transparency yellow flag). A label stating no amount at all is non-compliant — a checkable red flag. This panel states amounts; the open question is whether those declared amounts are independently verified and how they compare with relevant research.
vision:google/gemini-flash-1.5 Amounts are shown as declared panel data, not independently lab-tested contents.
These are the USPTO records behind the brand name. We show them all rather than choosing one by similarity.

This answers who owns registrations for the brand wordmark. It does not by itself prove which entity made, imported, or sold this specific product.
Review counts rose gradually. Written-review counts rose from 1,473 to 1,513 across the observed period. That describes count movement, not review authenticity or product quality. A variation family may share some public counts.

Confirmed evidence
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Open Food Facts resolves 031604018931 to "Calcium magnesium zinc" (Nature Made) — 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.
USPTO returned multiple live supplement-class records for the exact brand wordmark: PHARMAVITE LLC, PHARMAVITE CORPORATION. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.
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.
Published sources describe how magnesium, zinc 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 — Magnesium fact sheet, PubMed search: magnesium glycinate supplementation.
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.
The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.
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 1,473 on 2026-01-27 to 1,513 on 2026-07-15 (net +40). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
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 031604018931.
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.
