HIGH public verifiability
No contradictions found at this check depth Passed every check we could run — not an endorsement; read the record. Evidence availability only; this does not establish safety or effectiveness.
5 of 6 public trust signals found · 0 product-specific concerns
The short read
This supplement states it provides 30 mg of Zinc per tablet. This amount is a clear measurement from the product's Supplement Facts panel, which also agrees with the listing's claim. What remains unverified are the real-time authenticity of customer ratings and whether this specific product ever appeared in the NIH's label registry. You can check if the Supplement Facts panel on the bottle you have matches the 30 mg of Zinc (as Zinc Gluconate) listed here.
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 out05
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Confirmed
Listing claim matches the label panel
The listing claims 30 mg; the photo-read Supplement Facts panel shows Zinc (as Zinc Gluconate) at 30 mg per serving. The two independent statements agree.
Taken the way the research studied it
Nothing in this listing contradicts how these ingredients were studied (magnesium, zinc). 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.
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.
Barcode confirmed in an outside database
UPCitemdb resolves 885781087804 to "nature made zinc tabs - 30 mg - 100 ct" (Nature Made) — consistent with this listing.

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.
Reviews not analysed yet
Marketplace rating 4.7★ across 24,975 ratings. Authenticity not analysed: burst, purge and stockout patterns need price/review history.
Zinc amount, in daily-intake context
label states 30 mg/serving — about 75% of the adult daily reference (adult RDA 8–11 mg; NIH sets 40 mg/day as the tolerable upper limit for adults). A single serving isn’t meant to supply a full day, so this is context, not a shortfall. Caveat: chelate and gluconate labels may state compound mass rather than elemental zinc. Sources: NIH ODS — Zinc fact sheet, PubMed search: zinc supplementation trial.
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.
This brand had a recall in the past (now closed)
Brand-level history, not a finding about this product. Pharmavite recalled a product on 2016-06-06: “Specific lots of Nature Made(R) Vitamin D tablets may exceed specifications for yeast/mold.” (status: Terminated, case closed). 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.
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
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 885781087804.
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.
