Marketing check: 1 remains partly or independently unverified.
Rebuilt from public sources on July 23, 2026 · evidence availability is not a safety or effectiveness verdict.
Couldn’t verify means public proof was not found; it is not a mark against the product. Ingredient research is not treated as a trial of this exact product.
No named laboratory or lot-specific certificate was found for this exact product. No exact brand product page was available for a document check. IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur.
Headlines first. Open evidence only when you want the source trail.
What is advertised is what the label declares. This checks internal consistency; it is not an independent test of the contents.
The listing claims 0.125 mg; the photo-read Supplement Facts panel shows Vitamin D3 at 0.125 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.

Confirmed evidence
These checks found support in the public record. They confirm specific facts, not the product as a whole.

Documented concerns
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
We looked for these signals but could not settle them from public sources. A gap is not a strike.
The listing claims 0.125 mg; the photo-read Supplement Facts panel shows Vitamin D3 at 0.125 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.
The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.
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.
Exact-listing history records written-review counts from 34 on 2026-01-30 to 40 on 2026-06-30 (net +6). 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
Ask the brand or seller
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.
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.
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
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.
Scan the barcode on the package and confirm it reads 849720042125.
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.
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.
