FDA recall appears in this brand's history
An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.
Evidence and sources
Brand-level context only, not a finding about this product. Now Foods recalled a different or not-exactly-bound product on 2025-05-08: “regular yeast was inadvertently packaged as nutritional yeast” (status: Terminated). The recalled product was: “NOW Nutritional Yeast Powder, Nt…
Locked evidence record →Open the full source-linked findingChecks outCan you trust the review pattern?
Written reviews moved 2,076 → 2,100 from 2026-02-03 to 2026-07-05 without one large burst.
Gradual growth is more ordinary; a sudden burst deserves a closer look. Neither pattern proves whether individual reviews are genuine.
Evidence and sources
Written reviews grew from 2076 to 2100 across 2026-02-03 – 2026-07-05 with no single manufactured spike (largest 30-day gain ~13).

Confirmed evidence
What checked out01
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Reviews accumulated gradually
Written reviews grew from 2076 to 2100 across 2026-02-03 – 2026-07-05 with no single manufactured spike (largest 30-day gain ~13).
Documented concerns
What needs caution00
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 missing07
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 retained listing evidence does not establish net weight, unit count, 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.
FDA recall appears in this brand's history
Brand-level context only, not a finding about this product. Now Foods recalled a different or not-exactly-bound product on 2025-05-08: “regular yeast was inadvertently packaged as nutritional yeast” (status: Terminated). The recalled product was: “NOW Nutritional Yeast Powder, Nt. Wt. 10oz. UPC 7 33739 02460 2” — not necessarily the product on this page. Verify at FDA’s recall database.
Public label filing not retained
This record does not currently hold an identity-bound public label filing for the exact product. That is a LookCloser coverage gap, not evidence that no filing exists.
This item belongs to a catalog variation family
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.
180-day review-count history is on file
Exact-listing history records written-review counts from 2,076 on 2026-02-03 to 2,100 on 2026-07-05 (net +24). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
Barcode record is too sparse to confirm identity
Open Food Facts resolves 733739029263 to "Probiotique 25 billion" (brand not supplied), but that record lacks enough exact brand/product detail to confirm or contradict this listing.
Brand ownership record not retained
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
Which specific study supports this claim — and was it run on this exact formula?
Ask for the citation, how many people took part, the dose used, and whether the study tested this product or just one ingredient in it. Ingredient research is not product evidence.
2
Can you send a clear photo of the full Supplement Facts panel?
It’s the one part of the label required to state what’s inside and how much. A seller who won’t show it before purchase is asking for trust the label would have earned.
3
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
Scan the barcode on the package and confirm it reads 733739029263.
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.
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.
