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.

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.
The listing-image panel publishes an amount for each of its 2 listed rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Saccharomyces boulardii (an S. cerevisiae strain) | 250 mg | — | |
| MOS Yeast Fraction (Min. 35% Manno-oligosaccharides [MOS]) (S. cerevisiae) | 200 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
These checks found support in the public record. They confirm specific facts, not the product as a whole.
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
USPTO lists Jarrow Formulas, Inc. (CORPORATION) in CALIFORNIA, USA for the exact brand wordmark. This identifies the USPTO mark owner or applicant; it does not by itself prove who manufactures or sells this product.
Written reviews rose from 813 to 880 between July 18, 2025 and July 30, 2026. The largest rise inside any single 30-day window was about 16, so the count moved in steps rather than in one burst.
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 saved listing evidence does not establish net weight, unit count, per-serving dose, so the dose claim cannot yet be checked against serving arithmetic. This is a neutral evidence gap, not a pass or strike.
This recall is not about the product on this page. Jarrow Formulas Inc recalled a different product on January 15, 2018. FDA has since closed that case. The recalled item was “Jarrow Formulas Liquid L-Carnitine; 16 fl oz. (475 ml) bottle, dietary supplement; product number 102006; UPC 7 90011 02006 6; Vitamin B5 10 mg; L-Carnitine 1000 mg; Other i”. FDA recorded the reason as “A higher than normal micro result was found at the six month time point for one lot of Liquid L-Carnitine”. Verify at FDA’s recall database.
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 812 on 2025-07-10 to 880 on 2026-07-30 (net +68). 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
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.
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.
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.
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
| Claim | Status | What we found |
|---|---|---|
| Clinical-evidence claim “…CLINICALLY STUDIED PROBIOTIC…” | No evidence located We looked for: a named, citable clinical study of this product or formula | We found no named, citable study of this product or formula. The claim may rest on ingredient research rather than a trial of this product. |
| Benefit claim “Jarrow Formulas Saccharomyces Boulardii + MOS Probiotics for Digestive Health and Intestinal Tract Support - 5 Billion CFU Per Serving - 90 Delayed Release Caps - Probiot” | Not checked yet We looked for: whether the ingredient doses on the label match the doses used in published research | Ingredient-level evidence for this formula isn’t in our knowledge base yet. Recorded as not checked yet — not as a negative. |
“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.
Verifiability profile — 2 of 6 public signals
