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.
The 50 mg zinc (as zinc picolinate) claim matches the panel
We did the comparison: the listing claims 50 mg of zinc (as zinc picolinate), and the listing-image panel shows 50 mg zinc (as zinc picolinate) 1 capsule. Those amounts agree. This is internal consistency, not independent lab testing.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Zinc (as zinc picolinate) | 50mg | — |
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; any remaining comparison concerns the front-label framing.
vision:google/gemini-flash-1.5 Amounts are shown as declared panel data, not independently lab-tested contents.
Every check we ran
Dose claim implausibly high for a capsule
Claimed zinc 50.0 mg is 100% of the ≈50 mg serving (serving size on the label, keyed to UPC 810139573005) — above what gummy matrices realistically carry.
UPC independently corroborated
Open Food Facts resolves 810139573005 to "Zinc Picolinate" (Nutricost) — consistent with this listing.
Testing claim names a recognized certifier
A named certifier/laboratory appears in the listing (registry cross-check pending).
Listing claim matches the Supplement Facts panel
The listing claims 50 mg; the photo-read Supplement Facts panel shows Zinc (as zinc picolinate) at 50 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.
Zinc amount, in daily-intake context
label states 50 mg/serving — about 125% 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.
Research context is available for the listed ingredients
Published sources describe how 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 — Zinc fact sheet, PubMed search: zinc supplementation trial.
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.
180-day review-count history is on file
Exact-listing history records written-review counts from 459 on 2026-02-02 to 486 on 2026-07-20 (net +27). 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 |
|---|---|---|
| Quality-testing claim “…P Compliant, FDA Registered Facility quality THIRD PARTY TESTED NON-GMO GLUTEN-FREE MADE AND QUALITY TESTED…” | Partly supported We looked for: a named laboratory, a certificate of analysis, or a certification-registry entry | A testing body is named on the listing, but no lot-specific certificate of analysis was located. |
| Manufacturing claim “…luten Free Manufactured in an NSF Certified, GMP Compliant, FDA Registered Facility quality T…” | Claimed, not verifiable We looked for: the facility registration or certificate behind the claim | Facility-level claims can be accurate and still say nothing about this product’s contents. No registration document was located. |
“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.
This label vs. the doses studied
Why is this shown?
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Zinc (as zinc picolinate) | shaded = doses used in studies (8 mg–40 mg) · bar = this label | 50 mg — above the studied range |
Matching a studied dose does not mean the product works, and missing it does not mean it fails — it shows whether the label and the research are talking about the same amounts. Not a recommendation to take any amount.
Documented cautions

Where it sells
A brand storefront was found, but no exact-product price was published or identity-bound at build time.
Brand store nutricost.com: 199 supplement products (+51 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.
