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.
Panel, decoded
What the label discloses
2listed rows
2separately quantified
0combined blend totals
The listing-image panel publishes an amount for each of its 2 listed rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Vitamin D3 | 50 mcg mcg | — | |
| (as cholecalciferol) | (2,000 IU) IU | — |
FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a listed “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 listed amounts are independently verified and how they compare with relevant research.
vision:google/gemini-flash-1.5 Amounts are shown as listed panel data, not independently lab-tested contents.
Every check we ran
Confirmed evidence
What checked out4
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Confirmed
Exact trademark owner identified
USPTO lists HeartWise Inc. (CORPORATION) in OREGON, USA for the exact brand wordmark. This identifies the USPTO mark owner or applicant; it does not by itself prove who manufactures or sells this product.
Barcode confirmed in an outside database
Open Food Facts resolves 858081006400 to "Vitamin D3 50 Mcg (2,000 Iu)" (naturewise) — consistent with this listing.
Reviews accumulated gradually
Written reviews grew from 1709 to 1757 across 2026-01-31 – 2026-07-08 with no single manufactured spike (largest 30-day gain ~12).
Documented concerns
What needs caution0
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 missing3
We looked for these signals but could not settle them from public sources. A gap is not a strike.
Panel amounts are awaiting a clearer image read
The current image extraction saved 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.
Public label filing not saved
This record does not currently hold an matched to this exact product public label filing for the exact product. That is a LookCloser coverage gap, not evidence that no filing exists.
180-day review-count history is on file
Exact-listing history records written-review counts from 1,706 on 2026-01-29 to 1,757 on 2026-07-08 (net +51). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
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
Can you send the certificate of analysis (COA) for the lot number on my bottle?
A real COA names the testing laboratory, the test date, the lot it covers, and what was measured. “Third-party tested” with no document behind it is a marketing sentence.
2
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.
3
Where are the ingredients sourced, and where is the product manufactured?
“Made in USA” can describe only the final bottling step. Ask which country the actives came from and whether the facility is audited.
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 858081006400.
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.
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.
| Claim | Status | What we found |
|---|---|---|
| Quality-testing claim “…hey match label contents. USA MANUFACTURED & 3RD PARTY TESTED: This NatureWise supplement is manufactured…” | Partly supported We looked for: the observed listing, saved brand product page, any linked COA or test report; NSF, IFOS, USP, Informed-Sport were not queried | A testing body is named on the listing, but we found no lot-specific certificate of analysis. |
| 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 2000iu (50 mcg) 1-Year Supply for Immune Support, Healthy Muscle Function, and Bone Health -…” | Not checked yet 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 checked yet — 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.

Brand store naturewise.com: 115 supplement products (+1 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.
