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.
What the label discloses
The listing-image panel publishes an amount for each of its 2 declared rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Zinc (as zinc gluconate) | 15mg | — | |
| Copper (as copper bisglycinate) | 2mg | — |
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.
Every check we ran
Testing claim names a recognized certifier
A named certifier/laboratory appears in the listing (registry cross-check pending).
Panel amounts are awaiting a clearer image read
The current image extraction retained 2 ingredient name(s) but no usable amounts. This is a LookCloser processing gap, not evidence that the brand withheld the numbers; dose arithmetic is withheld until the panel is re-read.
Zinc amount, in daily-intake context
label states 15 mg/serving — about 38% 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.
Barcode record is too sparse to confirm identity
Open Food Facts resolves 810139572381 to "Zinc + Copper Supplement" (Nitricost), but that record lacks enough exact brand/product detail to confirm or contradict this listing.
180-day review-count history is on file
Exact-listing history records written-review counts from 76 on 2026-02-01 to 86 on 2026-03-22 (net +10). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Quality-testing claim “…MP Compliant facility for quality assurance. Third-party tested by independent ISO-accredited laboratories t…” | 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 “…functions. Manufactured in an NSF Certified GMP Compliant facility for quality assurance. Th…” | 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. |
| Benefit claim “…d use. Suitable for daily supplementation to support various bodily functions. Manufactured in an…” | Partly supported We looked for: whether the ingredient doses on the label match the doses used in published research | Ingredient evidence exists; on dose: label states 15 mg/serving — about 38% 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. |
“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 gluconate) | shaded = doses used in studies (8 mg–40 mg) · bar = this label | 15 mg — within 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
- zinc — daily oral use; sustained high intakes can interfere with copper absorption — a documented interaction, not advice
Statements from published sources about these ingredients — not advice about this product, and not a complete safety review. Anyone taking medication should talk to a pharmacist or clinician.

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.
