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.
Every check we ran
Intake method matches the research
Nothing in this listing contradicts how these ingredients were studied (zinc). For example, zinc: daily oral use; sustained high intakes can interfere with copper absorption — a documented interaction, not advice. Sources: NIH ODS — Zinc fact sheet, PubMed search: zinc supplementation trial.
Each ingredient’s 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.
No data yet: Label math could not be verified
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 yet: Testing claimed — documentation not found
The listing claims third-party testing without naming any lab or certifier, so the claim can't be verified as stated.
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.
Brand holds NSF/ANSI 173 certification (brand-level)
Thorne® appears in NSF’s certified-products registry with 10 certified product(s), but we couldn’t confirm this exact listing is among them. Closest listed product: “Thorne® Zinc Picolinate 30 mg”. Certification covers contents and contaminants — not effectiveness.
Barcode record is too sparse to confirm identity
Open Food Facts resolves 693749220022 to "Zinc picolinate" (brand not supplied), 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 287 on 2026-02-01 to 303 on 2026-07-14 (net +16). 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 “…Third-Party Certified: This product has been third-party tested and certified to verify what's in the packag…” | Claimed, not verifiable We looked for: a named laboratory, a certificate of analysis, or a certification-registry entry | No named laboratory, no certificate of analysis, and no certification-registry entry matching this product was located. |
| Benefit claim “…Supplement for Growth and Immune Function - Promotes Healthy Skin & Eyes* - Third-Party Certified…” | Partly supported We looked for: whether the ingredient doses on the label match the doses used in published research | Published research exists for ingredients in this formula — see Related research below. Whether this product’s doses match those studies could not be confirmed. |
“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 | 30 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.
Verifiability profile — 2 of 6 public signals
What this listing gives the public to check. Publishing these signals doesn't prove quality — but withholding them means claims can only be taken on faith.
