Every ingredient 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.

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
1listed rows
1separately quantified
0combined blend totals
The listing-image panel publishes an amount for each of its 1 listed row. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Niacin (as Niacinamide) (Vitamin B-3) | 500 mg | — |
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:claude-cli:subscription Amounts are shown as listed panel data, not independently lab-tested contents.
Every check we ran
Confirmed evidence
What checked out1
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Confirmed
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 missing4
We looked for these signals but could not settle them from public sources. A gap is not a strike.
The listing doesn't publish enough to check the math
The saved listing evidence does not establish net weight, per-serving dose, servings per container, so the dose claim cannot yet be checked against serving arithmetic. This is a neutral evidence gap, not a pass or strike.
Review-count history: not available
Marketplace rating not shown★ — rating count unavailable. No exact-listing count history was available, so no review-pattern claim is made.
FDA recall appears in this brand's history
This recall is not about the product on this page. Now Foods recalled a different product on May 8, 2025. FDA has since closed that case. The recalled item was “NOW Nutritional Yeast Powder, Nt. Wt. 10oz. UPC 7 33739 02460 2”. FDA recorded the reason as “regular yeast was inadvertently packaged as nutritional yeast”. Verify at FDA’s recall database.
Brand ownership record not saved
This record does not hold an exact, supplement-class public ownership record for the brand. That is a LookCloser coverage gap, not evidence that the brand has no owner or that the product is improper.
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
What is the product’s UPC or GTIN?
The barcode is how a product gets matched to outside records — certification registries, label databases, recall data. Without it, almost nothing can be cross-checked.
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.
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
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 |
|---|---|---|
| Manufacturing claim “…Produced in a GMP facility that processes other ingredients containing these allergens.…” | Partly supported We looked for: the facility registration or certificate behind the claim | “GMP-certified” describes factory processes, not what is in the bottle. The claim does not name a certifier or public register that a shopper can check. |
“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.

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.
