One product, one panel, one record.
OLLY Probiotic + Prebiotic Gummy, Peachy Peach (30 count) — label audit
The strain designator is printed on the physical label and absent from the brand's own website — MTCC 5856 appears zero times on olly.com's product page, where the copy calls the species a "strain". The brand did the expensive, honest thing and then threw the benefit away in the channel where people buy.
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, after the founding cohort of 27 was frozen. It sits outside every D27 denominator the site publishes.
- 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.
The Label Verifiability Score for this product
82.9 out of 100
Rank 29 of the 154 products in this audit the rubric can score. This rank is shared with 6 other products — 7 products sit on 82.9 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 "none-stated": CFU figure printed yes, single basis stated no, basis reaches expiry no — 1 of 3. | 1 / 3 = 0.3333 | 0.073333 |
| 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 |
0.713333 — the last column added up — divided by 0.86, the weight this record could answer, is 0.8295. Multiplied by 100 and rounded to one decimal, that is the 82.9 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 | 500 million CFU |
| What that count is measured against | No basis stated |
| Strain designators | All organisms coded |
| Organism slots transcribed here | 1 — the full panel |
| Marketed as | Unisex |
The probiotic row note on DSLD 230251 reads, in full, "500 million CFU". The 60-count record, DSLD 291259, reads the same. No temporal qualifier appears on any OLLY record for this SKU — not "at manufacture", not "at expiry". Every label statement in DSLD 291259 was checked for a potency-basis line; there is none. The only storage language is "Store in a cool, dry place." The website states no CFU at all: "CFU", "million" and "billion" each appear zero times on olly.com/products/probiotic-prebiotic. The figure reaches consumers only via the Amazon listing title ("500 Million CFUs") and the physical label.
The panel’s own words on potency, verbatim.
A CFU number appears with no temporal basis of any kind. A count with no basis is not a quantity; there is no date at which it is claimed to be true.
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 |
|---|---|---|---|---|
| Bacillus coagulans (correct name: Weizmannia coagulans) | MTCC 5856 | 33 mg — 500 million CFU | Human RCT | MTCC+5856 → 20; "Bacillus coagulans" AND "MTCC 5856" → 16; "MTCC 5856" AND randomized controlled trial[pt] → 3 (37335737, 36862903, 26922379) |
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 230251 (opens in a new tab) captured NIH label record for OLLY Probiotic + Prebiotic Peachy Peach, 30 count, on-market — and the panel this page is built on, because the UPC ties it to the live SKU. The barcode in olly.com's own product JSON is 858158005114 and this record's upcSku is 8 58158 00511 4: a match. Per 1 gummy: 5 calories, total carbohydrates 2 g (1% DV) of which dietary fibre 1 g and total sugars 1 g; Probiotic 33 mg — Bacillus coagulans MTCC 5856, note "500 million CFU"; Prebiotic Blend 1.5 g — fructooligosaccharides, inulin, xylitol. A third record, DSLD 205286 (30 count, 2019, off-market), lists the organism with no designator at all and is the evidence that disclosure improved between 2019 and 2020; it is not listed separately here because its entry date was not recovered.
- NIH Dietary Supplement Label Database record — DSLD 291259 (opens in a new tab) captured OLLY Probiotic + Prebiotic Peachy Peach, 60 count, UPC 8 40160 20065 6. Corroborates the same "500 million CFU" note and is the record whose every label statement was checked for a potency-basis line — there is none. Its transcribed Seals/Symbols element lists only "Certified B Corporation", with no NSF seal, and it carries the cross-contact allergen statement verbatim: "Processed in a facility with products that may contain soy, egg, peanuts, tree nuts, milk, fish, shellfish and wheat."
- Dated capture of the brand’s own page — olly-probiotic-prebiotic-2026-07-31https://www.olly.com/products/probiotic-prebiotic — Address given, not linked: this site does not link out to the products it audits. captured HTTP 200, fetched directly along with the product JSON (/products/probiotic-prebiotic.js) and the gut-health collection index. Source of the price, the live barcode 858158005114 that matches DSLD 230251, the "All Gone, Back Soon" availability, the NSF FAQ answer, the accurate supply-duration FAQ, and the zero counts for "MTCC", "CFU", "million" and "billion" across the full page text.
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 it costs per day
$0.47 a day at the dose the label itself instructs.
- Price
- $13.99 USD
- What that buys
- 30-gummy bottle, 1 gummy daily, 30 servings ($13.99 ÷ 30 = $0.4663). The 60-count is $23.99, or $0.3998 a day. Shipping is $6.99 flat, free over $49; returns are 30 days. The 30-count was listed "All Gone, Back Soon" — out of stock at the brand's own store — at the time of this pass. No per-serving unit price is advertised, so there is no arithmetic error to catch, and the FAQ states the supply duration correctly: "The 30-count bottle provides a 30-day supply, while the 60-count bottle provides a 60-day supply."

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 |
|---|---|---|
| NSF (programme not named by the brand) | Register unreachable | 31 July 2026 |
| Certified B Corporation | Register unreachable | 31 July 2026 |
NSF (programme not named by the brand)
The certifier’s register could not be queried at all. That is a finding about the verification infrastructure, not about the brand.
The website FAQ states, verbatim, "Are OLLY Probiotic + Prebiotic gummies certified for quality? Yes, they are NSF certified, meaning they've been independently tested and certified to meet rigorous standards for quality, safety, and label claims." The claim could not be verified at the issuer: nsf.org returns 403 to automation, and listings.nsf.org is a JS-gated Angular SPA whose backend API could not be located — every candidate route returned the 22 KB SPA shell, and the main JS bundle contains no API base URL. This is a statement about access, not about the brand's honesty, and it may never be read as "not certified". Two scope notes travel with it. First, the copy does not say which NSF programme: NSF runs facility GMP registration, NSF/ANSI 455-2 dietary-supplement GMP certification, product Contents Certified and Certified for Sport, which certify very different things, and "quality, safety, and label claims" is phrasing consistent with contents certification without naming it. One search snippet described the product as "Contents Certified"; that could not be confirmed at NSF's register and is not asserted. Second, the physical label does not carry an NSF seal — DSLD 291259's transcribed Seals/Symbols element lists only "Certified B Corporation" — so on the records available this is a website claim, not a label claim.
Certified B Corporation
The certifier’s register could not be queried at all. That is a finding about the verification infrastructure, not about the brand.
bcorporation.net returned 403 to both curl and WebFetch, so B Lab's register could not be queried. The seal is transcribed as a Seals/Symbols element on the physical label in DSLD 291259, which is a second independent sighting of it but is not the issuer's register. Brand-asserted, unverified — never "not a B Corp".
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.
This brand sells no women’s counterpart to this product, so there is no diff to run.

The full text of olly.com/products/probiotic-prebiotic was searched: "MTCC" appears 0 times. The page says only "Bacillus coagulans, the good bugs that work with your body's natural bacteria…" and its FAQ asks "What is Bacillus coagulans?" and answers "Bacillus coagulans is a probiotic strain…" — calling a species a strain, on the page selling a product whose label names the actual strain. A consumer reading the website cannot distinguish this product from an anonymous store-brand B. coagulans gummy, even though on the label they are meaningfully different products.

The FAQ says the gummies are "NSF certified" and describes it as covering "quality, safety, and label claims", but NSF runs facility GMP registration, NSF/ANSI 455-2 GMP certification, product Contents Certified and Certified for Sport, which certify very different things. The transcribed physical label carries no NSF seal at all — only "Certified B Corporation".

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.
- NSF (programme not named by the brand) status
- The website FAQ states, verbatim, "Are OLLY Probiotic + Prebiotic gummies certified for quality? Yes, they are NSF certified, meaning they've been independently tested and certified to meet rigorous standards for quality, safety, and label claims." The claim could not be verified at the issuer: nsf.org returns 403 to automation, and listings.nsf.org is a JS-gated Angular SPA whose backend API could not be located — every candidate route returned the 22 KB SPA shell, and the main JS bundle contains no API base URL. This is a statement about access, not about the brand's honesty, and it may never be read as "not certified". Two scope notes travel with it. First, the copy does not say which NSF programme: NSF runs facility GMP registration, NSF/ANSI 455-2 dietary-supplement GMP certification, product Contents Certified and Certified for Sport, which certify very different things, and "quality, safety, and label claims" is phrasing consistent with contents certification without naming it. One search snippet described the product as "Contents Certified"; that could not be confirmed at NSF's register and is not asserted. Second, the physical label does not carry an NSF seal — DSLD 291259's transcribed Seals/Symbols element lists only "Certified B Corporation" — so on the records available this is a website claim, not a label claim.
- Certified B Corporation status
- bcorporation.net returned 403 to both curl and WebFetch, so B Lab's register could not be queried. The seal is transcribed as a Seals/Symbols element on the physical label in DSLD 291259, which is a second independent sighting of it but is not the issuer's register. Brand-asserted, unverified — never "not a B Corp".
- What the "500 million CFU" figure is measured against
- No temporal qualifier appears on any OLLY record for this SKU. Every label statement in DSLD 291259 was checked for a potency-basis line and there is none; the only storage language is "Store in a cool, dry place." A buyer cannot establish whether the number is measured at manufacture or at the moment of swallowing. This is a finding, not a failure of searching.
- OLLY's NSF certification, at NSF's own register
- nsf.org returns 403 to automation and listings.nsf.org is an Angular SPA whose backend API could not be located — every candidate route returned the 22 KB shell, and the main JS bundle contains no API base URL. Recorded as brand-asserted and unverified, never as absent. The brand also does not say which NSF programme it means, and the four NSF programmes certify materially different things.
- OLLY's Certified B Corporation status, at B Lab's register
- bcorporation.net returned 403 to both curl and WebFetch. The seal is transcribed on the physical label in DSLD 291259, which is a second sighting but not the issuer.
- Funding and conflict-of-interest statements for the three MTCC 5856 RCTs
- All three are authored by Majeed and colleagues and all three name LactoSpore®, the trade name of the strain's owner, Sami/Sabinsa. That is an affiliation inferred from authorship and product name, not a funding statement read from full text — full text was not pulled. No funding characterisation is published here for that reason, and none should be quoted from this page.
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.
This product should not be lumped in with the rest, and its failure is specific.
Start with what it gets right, because it is rare. One organism. A real strain designator on the panel — Bacillus coagulans MTCC 5856, deposited, heavily published, and the single most valuable label property in this category. The UPC on the brand’s own product JSON matches the NIH label record, so the panel on this page is demonstrably this SKU’s panel and not a near neighbour’s. Disclosure improved over time: the 2019 record names the species and nothing else; the 2020 record adds the designator. The claim writing is the most disciplined in its batch — every claim hedged, the FDA disclaimer present, no disease claim, no “clinically proven”, no superiority claim, no uncited percentage, no men’s-health fiction. The supply-duration FAQ is accurate, no misleading unit price is advertised, and the cross-contact allergen statement is volunteered rather than dodged.
Then the brand hides its own best asset. The full text of its product page was searched: MTCC appears
zero times. So do CFU, million and billion. The page says “Bacillus coagulans, the good bugs…” and
the FAQ answers “Bacillus coagulans is a probiotic strain” — calling a species a strain, on the page selling
a product whose label names the actual strain. OLLY did the hard, expensive, honest thing and then threw the
benefit away in the channel where most people actually buy. A shopper on olly.com cannot tell this product
apart from an anonymous store-brand B. coagulans gummy.
And the dose is a quarter of the evidence. Every published RCT of MTCC 5856 used 2 billion CFU/day — PMID 26922379 in IBS-D patients, PMID 36862903 in adults with functional gas and bloating, PMID 37335737 in healthy adults, that last one being the only trial whose population resembles this product’s buyer. This gummy delivers 500 million. The honest sentence is: OLLY names a real strain with real trials — at four times the dose OLLY gives you. Two of those three trials were also run in symptomatic patient populations, and OLLY makes no IBS claim, so they would not transfer to its claim set even if the dose matched.
The last gap is the one this whole site exists for. The 500 million has no stated basis. Not at manufacture, not at expiry — every label statement on the 60-count record was read looking for one. A buyer has no way to know what fraction of that quarter-dose is alive when they chew it.
