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

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.

UPC independently corroborated

Open Food Facts resolves 858081006042 to "Vitamin D3" (Naturewise) — consistent with this listing.

Testing claim names a recognized certifier

A named certifier/laboratory appears in the listing (registry cross-check pending).

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: Trademark owner candidates are ambiguous

USPTO returned multiple live supplement-related marks with the exact brand wordmark and different registrants. The owner is withheld until the product-to-mark identity is pinned down.

No data yet: Review-count history: not available

Marketplace rating 4.8★ across 145,597 ratings. No exact-listing count history was available, so no review-pattern claim is made.

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.

What the listing promises — claim by claim

Why is this shown?
A listing’s promises are the reason people buy. Each one gets its own row: what was promised, what evidence would settle it, and what we could actually find. We never call a claim false — only whether proof proportionate to it exists on the public record.
ClaimStatusWhat we found
Quality-testing claim
“…hey match label contents. USA MANUFACTURED & 3RD PARTY TESTED: This NatureWise supplement is manufactured…”
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.
Origin claim
“…PARTY TESTED: This NatureWise supplement is manufactured in the USA in a facility that follows cGMP and undergoe…”
Claimed, not verifiable
We looked for: customs records or label filings showing where ingredients were sourced and where it was made
“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.
Benefit claim
“…D3 5000iu (125 mcg) 1 Year Supply for Immune Support, Healthy Muscle Function, and Bone Health, G…”
Not assessed
We looked for: whether the ingredient doses on the label match the doses used in published research
Ingredient-level evidence for this formula isn’t in our knowledge base yet. Recorded as not assessed — not as a negative.

“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.
