Specific fact confirmed

The listing-image panel publishes an amount for each of its 0 declared rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| N-Acetyl-Csyteine | — | — |
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.

This is the USPTO owner of the brand wordmark. It tells a shopper who is behind the brand, but does not by itself identify the manufacturer or prove where this product was made.
The summary stops at product-specific facts. The full report preserves every source, calculation, limitation, and unresolved check for review or sharing.
Confirmed evidence

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.
Marketplace rating not shown★ — rating count unavailable. No exact-listing count history was available, so no review-pattern claim is made.
Brand-level context only, not a finding about this product. MARY RUTH ORGANICS recalled a different or not-exactly-bound product on 2021-10-28: “Internal testing found the presence of Pseudomonas aeruginosa in the product.” (status: Terminated). The recalled product was: “MaryRuth's Organic Infants Liquid Probiotic; Unflavored, a Dietary Supplement. 1 fl. oz.

The current image extraction retained 1 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.
The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.
What to ask and check
Ask the brand or seller
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 810104621168.
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.
