One product, one panel, one record.
Florastor Florastor Probiotic, 30 Capsules — label audit
A "30 Capsules" bottle reads as a month. At the label's own serving size — 2 capsules, one to two times daily — it is a 15-day supply, and 7.5 days at its own maximum. The government record's servings field says "30", because it is echoing the capsule count, so anyone computing cost per day from it understates it by two to four times.
This page is an audit of a label. It records what this product’s panel discloses, what of that could be checked against a primary record, and what could not. The score below ranks this product on that disclosure and on nothing else.
The record this page rests on
- NIH label record
- Label read on
- The most recent dated artefact behind this page. Labels change; this is how old our reading of it is.
- Cohort
- Addendum — outside the founding denominators Torn down 2026-07-31, outside the frozen founding cohort of 27 and outside every D27 denominator.
- How deep this went
- Full forensic teardown Panel transcribed, every strain designator queried, every certification chased to its issuer’s own register, and the literature behind each marketing claim opened and read.
- What did not survive verification
- Part of this page was refuted or could not be reproduced The identity of the package this listing ships is not settled, and this page says so rather than choosing. The URL lineage in the brief 301s to a 404, the brand's live catalogue contains no "Daily" SKU, and the flagship 30-count is now sold as Florastor Dual Action — while the retail listing title still reads "Florastor Probiotic … 30 Capsules" and does not say Dual Action. Whether it ships the current carton or legacy stock under the old name cannot be proven from public data. Nor can the listing be tied to a government record by barcode: the 30-count record 206744 carries no UPC field at all, and the record that does carry one is the 50-count, so the tie is identical Supplement Facts content — corroboration of formula, not proof of package. And no price for the listing itself is published, because every Amazon buybox in this session was geo-suppressed and three retailer fallbacks failed; the $28.97 here is the brand's own direct price for the same count. What survives all of that intact, because the panel is identical across both records and both names: the strain and its designator, the 250 mg per capsule, the absence of any CFU figure, and the 15-day supply arithmetic.
The Label Verifiability Score for this product
74.4 out of 100
Rank 46 of the 154 products in this audit the rubric can score. This rank is shared with 2 other products — 3 products sit on 74.4 and are tied. They hold the position jointly; no tiebreaker is applied, because every tiebreaker available here would be a number the rubric deliberately refused to weigh, smuggled back in to make a list look tidier.
The score measures one thing: how much of what you are buying this company tells you, and how much of that survives being checked against a source that is not the company. It does not measure whether the product works — this site holds no efficacy data of its own, and 0 of 294 organism slots in the founding cohort carry a strain with a human randomised trial for any male-specific outcome, so nobody in this category has evidence that would support a ranking by effect.
Computed over 86% of the rubric by weight — the share of the five questions below this record could answer. The remaining question is unanswered, and unanswered is not nought: it leaves the divisor rather than dragging the score down. That share travels with the number and is never dropped — this score over 86% of the weight and the same score over all of it are different claims.
| Component | Weight | What was counted, and where | Fraction | Weight × fraction |
|---|---|---|---|---|
| Strain identity printed on the panel | 0.24 | 1 of 1 organism slot carries a printed strain designator. | 1 / 1 = 1.0000 | 0.2400 |
| Per-organism amount printed | 0.20 | 1 of 1 organism slot has an amount of its own; the rest are inside a blend total. | 1 / 1 = 1.0000 | 0.2000 |
| What the CFU count is measured against | 0.22 | Potency basis "no-cfu-number": CFU figure printed no, single basis stated no, basis reaches expiry no — 0 of 3. | 0 / 3 = 0.0000 | 0.0000 |
| Printed designators that lead to a human trial | 0.20 | 1 of 1 checked organism slot resolves to at least one human randomised trial under the designator exactly as printed. This counts whether the identity leads to a trial, never what the trial found. | 1 / 1 = 1.0000 | 0.2000 |
| Certification confirmed at the issuer’s own register | 0.14 | Every certification on this record is brand-asserted with the register unreachable, or not yet queried. An unreachable register is a fact about the verification infrastructure, not about this brand, so it may not move its position. | Not answered | — excluded from the divisor, not counted as nought |
0.6400 — the last column added up — divided by 0.86, the weight this record could answer, is 0.7442. Multiplied by 100 and rounded to one decimal, that is the 74.4 above.

What this label discloses
Everything in this table is what the product itself states — on the printed panel, on the brand’s own page, or in the label record the manufacturer filed. Nothing in it is checked yet; checking is the next section.
| Disclosure | As recorded |
|---|---|
| CFU as printed | No CFU figure recorded |
| What that count is measured against | No CFU figure |
| Strain designators | All organisms coded |
| Organism slots transcribed here | 1 — the full panel |
| Marketed as | Unisex |
No CFU figure appears anywhere on the panel.
Every organism on the panel carries a printed strain designator. Whether those designators lead anywhere is a separate question, answered below.
| Organism as printed | Designator as printed | Quantity as printed | What the designator resolves to | The query we ran |
|---|---|---|---|---|
| Saccharomyces boulardii | CNCM I-745 | 250 mg per capsule (500 mg per 2-capsule serving) | Human RCT | ("CNCM I-745"[tiab] OR "CNCM-I 745"[tiab] OR "Saccharomyces boulardii CNCM I-745"[tiab]) AND (randomized controlled trial[pt] OR randomised[tiab] OR randomized[tiab]) |
What of that is verifiable
A disclosure is verifiable when a reader can open a record that neither we nor the brand controls and see the same thing. Below is every dated artefact this page rests on. What is absent from this list is not verified, however reasonable it sounds.
- NIH Dietary Supplement Label Database record — DSLD 206744 (opens in a new tab) captured The 30-count Florastor record. Carries no UPC field, which is why it cannot be tied to the retail listing by barcode. Source of the 250 mg quantity, the "For men and women" printed statement and the 2019 lifestyle copy.
- NIH Dietary Supplement Label Database record — DSLD 270390 (opens in a new tab) captured The 50-count record, UPC 7 04142 00007 1. Same Supplement Facts content — 250 mg plus lactose 32.5 mg per capsule, same two other ingredients — which is what ties the 30-count to a verified panel by formula rather than by package.
- Dated capture of the brand’s own page — florastor-dual-action-pdp-2026-07-31https://www.florastor.com/products/florastor-dual-action-probiotic-supplement — Address given, not linked: this site does not link out to the products it audits. captured The brand's current 30-count equivalent, SKU 76888, fetched HTTP 200. Source of the $28.97 price, the serving instruction, the absent CFU strings and the nine-product catalogue.
How many of its strains have a human trial for what it is sold for
Across the frozen founding cohort, 0 of 294 organism slots (0.0%) carry an organism with a human randomised controlled trial for any male-specific outcome. Not for this product — for all 27 of the founding teardowns, taken together. That is the number to hold against any men’s probiotic, including this one.
Two further founding-cohort figures for context: only 43 of 294 organism slots carry a strain with any human RCT at all under the exact code printed on the label, and only 2 of 27 products have a published human trial of the finished formula — the thing actually in the bottle. All three figures divide by the frozen cohort of 27 teardowns and 294 organism slots, never by every teardown on this site.
For this product specifically, 1 organism slot carries a strain with a human RCT under the exact designator printed on the label.
A word on what a designator has to clear before it counts here. The organism must be named with the exact strain code that appears in the trial, the trial must be in humans, and the code must return that trial when a reader searches it. A species name does not qualify: the trials in this field are of strains, and a species contains thousands of them.

What certification it holds, checked at the issuer’s own register
A badge on a bottle is a claim like any other. Every row below was checked — or not checked — at the certifier’s own public register, never at the badge. Across the frozen founding cohort, 2 of 27 products hold a certification we could confirm at the issuer — a founding-cohort figure, not a count over every teardown on this site.
| Programme | Status at the issuer | Checked |
|---|---|---|
| Any third-party certification | Not checked | 31 July 2026 |
Any third-party certification
We have not queried this register for this product. It does not mean the product holds nothing.
None is claimed, so there is no issuer register to check — a different and weaker statement than "claimed but unverifiable". A word-boundary scan of the brand page for NSF, USP Verified, Informed-Choice, Non-GMO Project, ConsumerLab, cGMP, third-party tested and certified by returned zero hits on every term. What is claimed is gluten-free, vegetarian, non-GMO, titanium-dioxide-free (per DSLD 270390) and "appropriate for lactose intolerance". "Non-GMO" here is a bare brand assertion, not the Non-GMO Project Verified mark.
How it differs from the same brand’s women’s version
Across the fourteen same-brand men’s-versus-women’s label diffs run inside the frozen founding cohort, zero men’s or default formulas contain a probiotic strain, identified by designator, that was selected on male-specific evidence. In eight of the fourteen the sex-specific differentiator is a botanical or a mineral, and in five of the fourteen the women’s SKU is better-specified, cheaper, or both — “better-specified” meaning the panel that discloses more, never the panel with more in it. The rule behind each of those counts, and all fourteen pairs classified against it , are published in full. Diffs run on teardowns added since sit outside this fourteen, and outside the sentence above.
Compared against Her Florastor® Balanced Benefits Digest + De-stress. Diffed .
What the two panels differ by
- The brand's only sex-targeted SKU is the women's one, and it is priced identically to the unisex flagship — 30 ct $28.97, 90 ct $59.99, against this product's 30 ct $28.97. Brand copy: "Designed specifically for women". It adds L-theanine and a vaginal-microbiota positioning that this product has no counterpart to. florastor.com/products.json, 9-SKU live catalogue, read 2026-07-31
- There is no "His Florastor" and no men's SKU of any kind among the nine products in the catalogue. florastor.com/products.json, 9-SKU live catalogue, read 2026-07-31
What is identical across the pair

Every finding on this page, with the record behind it
Finding 1 thirty-capsules-is-a-fifteen-day-supply
Serving size is 2 capsules, "1–2 times daily" — three-way agreement between DSLD 206744, the brand page and the retail listing. So the bottle is 15 servings at the minimum dose and 7.5 at the maximum. Real cost per day is $1.93 to $3.86.

Finding 2 government-servings-field-echoes-the-capsule-count
DSLD's servingsPerContainer field reads "30" for the 30-count record and "50" for the 50-count — it is reporting capsules, not servings, on a product whose serving is two capsules. Anyone computing cost per day from that field understates it by two to four times. Do not use it for this SKU.
The record: DSLD 206744 and DSLD 270390 — open it (opens in a new tab)
Finding 3 no-cfu-count-anywhere
"CFU" and "billion" each appear zero times on the brand product page and zero times in the listing's own copy — both strings occur there only inside sponsored-competitor ad markup. Both government records give the quantity as 250 mg with no CFU value and no potency footnote. There is no potency-at-expiry guarantee of any kind. The nearest related claim is a shelf-life assertion: "Our patented freeze-drying process gives Florastor a three-year shelf life protecting the live cells without refrigeration."

Finding 4 supplement-facts-is-machine-unreadable
The brand page renders the panel as an image; its HTML text gives the strain name with no quantity beside it at all — "Per 2 capsule serving: Saccharomyces boulardii CNCM I-745". The milligram figure had to be recovered from the government record and the listing's ingredient statement.

Finding 7 womens-line-exists-mens-does-not
Her Florastor is in the nine-product catalogue at the same 30-count price. There is no His Florastor and no men's SKU of any kind — yet this SKU is routinely listed as a men's pick.

Finding 8 protect-against-multiple-gi-issues
The closest thing to disease-claim territory on this label. "Protect against … GI issues" is doing real work with an asterisk under it; "GI issues" is vague enough not to name a disease, which is what keeps it inside the line.

What we could not verify
Every gap below is published rather than deleted. Most are derived automatically from the empty fields in this page’s own record, so a gap cannot be hidden by leaving a box blank.
- The CFU figure on the panel
- No CFU figure was recorded for this product. Either the panel prints none or it was not transcribed; this teardown does not yet distinguish between the two.
- Any third-party certification status
- None is claimed, so there is no issuer register to check — a different and weaker statement than "claimed but unverifiable". A word-boundary scan of the brand page for NSF, USP Verified, Informed-Choice, Non-GMO Project, ConsumerLab, cGMP, third-party tested and certified by returned zero hits on every term. What is claimed is gluten-free, vegetarian, non-GMO, titanium-dioxide-free (per DSLD 270390) and "appropriate for lactose intolerance". "Non-GMO" here is a bare brand assertion, not the Non-GMO Project Verified mark.
- The price of the listing this teardown was taken from
- Amazon buyboxes were geo-suppressed for the whole session — every one returned a restricted-shipping-to-Spain notice instead of a price block — and cvs.com 403'd, walmart.com bot-blocked and target.com 404'd. The figure published here is the brand's own direct price for the same 30-count, not the retail price of the ASIN.
- A UPC tie between the retail listing and the government records
- The listing reports UPC 704142000354. The DSLD 30-count Florastor record, 206744, carries no UPC field at all, and the record that does carry one, 270390, is the 50-count (7 04142 00007 1). The two sources cannot be tied by UPC. They are tied by identical Supplement Facts content — 250 mg plus 32.5 mg lactose, same two other ingredients — which is corroboration of formula, not proof of package identity.
- Which carton the retail listing currently ships
- The URL lineage in the brief 301s to a 404, the brand's live catalogue contains no "Daily" SKU, and the flagship 30-count is now sold as "Florastor® Dual Action Probiotic Supplement" — while the retail listing title still reads simply "Florastor Probiotic … 30 Capsules" and does not say Dual Action. Whether that listing ships the Dual Action carton or legacy stock under the old name cannot be proven from public data. The Supplement Facts are identical either way, so the formulation findings hold regardless; only the carton identity is ambiguous.
How to check every line of this page yourself
Nothing on this page requires trusting us. Every claim above resolves to a record you can open:
- Open the NIH Dietary Supplement Label Database record linked at the top of this page. It is the label the manufacturer filed, not our transcription of it.
- Compare the CFU line and the suggested-use line against the disclosure table above. If they disagree with us, we are wrong and we want to know.
- Take any strain designator from the panel and run the query printed beside it. The query is published precisely so you can get a different answer than we did.
- Divide the price by the number of days the label’s own dose instructions make the container last. That arithmetic is the whole of the cost-per-day row.
- Search the certifier’s own register for this product, not for the brand. A company can participate in a programme without this product being on its list.
The pack size is the finding.
Thirty capsules reads as a month. The serving size on this label is two capsules, “1–2 times daily” — and the brand page, the government record and the retail listing all agree on it. So the bottle is 15 days at the minimum dose and 7.5 days at the maximum. Real cost per day: $1.93 to $3.86, the highest in its batch by a wide margin against a single-strain competitor at $0.60.
The government database makes it worse rather than better. DSLD’s servingsPerContainer field reads
“30” for this record and “50” for the 50-count — it is echoing the capsule count on a product whose
serving is two capsules. Anyone computing cost per day from that field is out by a factor of two to
four. Do not use it for this SKU.
The strain itself is excellent. Saccharomyces boulardii CNCM I-745 — a real Institut Pasteur deposit, 24 randomised records under the designator, clustering on antibiotic-associated diarrhoea and Clostridioides difficile. One of one disclosed strains is matchable to human evidence at the exact code.
And that produces the tension worth naming: the strain’s literature is overwhelmingly about treating and preventing disease states, which a dietary supplement label may not say. So the marketing is forced into vaguer territory — “flush out unwanted bacteria” — that is weaker than the actual evidence while being untethered from it, because a buyer taking this for general “gut health” is not the population that was studied.
There is no CFU count anywhere: not on the page, not in the listing’s own copy, not in either government record. No potency-at-expiry guarantee either — what exists is a shelf-life assertion about freeze-drying. And no third-party certification is claimed at all, which is a different and weaker thing than a claim that could not be checked: a word-boundary scan for NSF, USP Verified, Informed-Choice, Non-GMO Project, ConsumerLab, cGMP and third-party tested returned zero hits on every term.
Finally, the gendering. The label’s own words are “For men and women”, transcribed as printed copy in both government records. The brand ships Her Florastor at the same 30-count price and no “His” anything. This product is in men’s roundups because it is the highest-selling single-strain probiotic in the US pharmacy channel, not because anything in it is male-specific.
