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

amount differsWe compared the listing claim (500 mg) with the panel row (1 g organic spirulina (arthrospira platensis)). They do not match within the report tolerance; the source label or serving basis needs checking.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Protein | < 1 g | — | |
| Organic Spirulina (Arthrospira platensis) | 1 g | — |
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; any remaining comparison concerns the front-label framing.

Every check we ran
Confirmed evidence
What checked out2
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Confirmed
The review count moved gradually, not in one burst
Written reviews rose from 81 to 86 between November 23, 2025 and July 7, 2026. The largest rise inside any single 30-day window was about 5, so the count moved in steps rather than in one burst.
Documented concerns
What needs caution1
These are documented contradictions or claims that need more evidence. They are separate from missing data.
The listing says 500 mg of spirulina; the panel says 1,000 mg
We could not find an explanation for the difference — no blend, extract ratio, compound form or multi-capsule serving accounts for it. You are getting 1,000 mg of spirulina per serving. Worth asking the brand which number describes the capsule you swallow.
Unresolved public record
What is still missing6
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.
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.
Public label filing not saved
We have not found a public label filing for this exact product. That is a gap in our records, 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 79 on 2025-10-21 to 86 on 2026-07-07 (net +7). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
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
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
Scan the barcode on the package and confirm it reads 733739026965.
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 |
|---|---|---|
| Manufacturing claim “…GMP Quality Assured: A-rated, third-party certification means that every aspect of the NOW manufacturing process has been examined.…” | 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.
