One product, one panel, one record.
Nature Made Probiotic + Prebiotic Fiber Gummies, 50 ct, Mixed Berry (Item HL000585) — label audit
The tightest claim-to-evidence match in this project. The product advertises relief of occasional gas and bloating, and its single named strain — Bacillus coagulans MTCC 5856 — has a placebo-controlled human trial on that exact endpoint (PMID 36862903). Almost nothing else audited here achieves that. It also has maltitol as its second ingredient and a label warning that it may cause the symptom it sells relief from.
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
- No NIH Dietary Supplement Label Database record is on file for this product in this teardown.
- 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 Audited 2026-07-31, outside the frozen founding cohort of 27 and outside every D27 denominator.
- How deep this went
- Label audit — the lighter pass What the label says, what basis it gives for its CFU number, whether the strains are coded, whether a government label record exists — checked and published. No full claim inventory was written for this SKU. It is a real result, and it is a shallower one than the teardowns above it, which is why the page says so before you weigh it against them.
The Label Verifiability Score for this product
100.0 out of 100
Rank 1 of the 154 products in this audit the rubric can score. This rank is shared with 18 other products — 19 products sit on 100.0 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 "through-expiry": CFU figure printed yes, single basis stated yes, basis reaches expiry yes — 3 of 3. | 3 / 3 = 1.0000 | 0.2200 |
| 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 |
0.8600 — the last column added up — divided by 0.86, the weight this record could answer, is 1.0000. Multiplied by 100 and rounded to one decimal, that is the 100.0 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 | 2 Billion CFU per 2-gummy serving (15 mg LactoSpore, Bacillus coagulans MTCC 5856) |
| What that count is measured against | Through expiry |
| Strain designators | All organisms coded |
| Organism slots transcribed here | 1 — the full panel |
| Marketed as | Unisex |
"Formulated to provide at least 2 billion live cells per serving if continuously stored in a cool, dry place at or below 75F (23C) and consumed prior to expiration date." Printed on the label panel — and absent from the product page HTML, where searches for both "Formulated to provide" and "live cells" return zero while both strings are present on the two sibling pages.
The panel’s own words on potency, verbatim.
The panel guarantees the count through the expiration or best-by date. This is the only basis that is falsifiable by a reader holding the bottle.
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 | MTCC 5856 (LactoSpore) | 15 mg, 2 Billion CFU | Human RCT | "MTCC 5856"; "MTCC5856"; LactoSpore |
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.

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 |
|---|---|---|
| USP Verified | Register unreachable | 31 July 2026 |
| "#1 Pharmacist Recommended Vitamin & Supplement Brand" | Not checked | not checked |
USP Verified
The certifier’s register could not be queried at all. That is a finding about the verification infrastructure, not about the brand.
No USP mark on the label panel and no "USP" string in the page HTML — a label and page observation, not a register result. usp.org and quality-supplements.org both return HTTP 403. Neither verified nor not verified may be published.
"#1 Pharmacist Recommended Vitamin & Supplement Brand"
We have not queried this register for this product. It does not mean the product holds nothing.
A survey claim, not a certification.
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.
Every finding on this page, with the record behind it
Finding 1 maltitol-and-inulin-in-a-gas-and-bloating-product
Maltitol, a sugar alcohol with a well-known osmotic gas literature, is the second ingredient, and each serving carries 3 g of inulin, itself a fermentable prebiotic with a dose-dependent gas literature. The label's own Suggested Use reads "If gas, bloating, or stomach upset occurs, reduce daily serving." The product warns you it may cause the symptom it is sold to relieve, and both halves of that sentence are the brand's own label text.
The record: Ingredients and Suggested Use, verbatim from brand label image NM-HL000585-PK002701-PRO--PREBIOTIC-FIBER-GUMMIES-back.jpg
Finding 2 cfu-basis-on-the-label-but-not-on-the-page
A buyer reading the web page cannot learn the CFU basis; a buyer holding the bottle can. The dagger footnote survives only inside the panel image. Both strings that carry it are present on the two sibling product pages and absent from this one.
The record: naturemade.com product page HTML searched for "Formulated to provide" and "live cells", both zero
Finding 3 lowest-cfu-in-its-batch-at-the-lowest-price
2 billion CFU per serving at $0.96 a day, which is both the cheapest per day and the second-most expensive per billion CFU ($0.48) among the five products audited alongside it. Both facts belong in the same sentence, and neither settles anything — a designated strain at a trial-matched dose is worth more than an undesignated large number.
The record: $23.99 over 25 servings at 2 billion CFU per serving
Finding 4 no-government-label-record
No DSLD record exists for this SKU, verified on two query paths plus a 597-record brand sweep.

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 $0.96-a-day supermarket gummy does something almost nothing else in this project manages: it names its strain, and the strain has a placebo-controlled human trial on the exact endpoint the product advertises. The claim is relief of occasional gas, bloating, burping and abdominal discomfort. The strain is Bacillus coagulans MTCC 5856, sold as LactoSpore, and PMID 36862903 is a randomised, double-blind, placebo-controlled trial of that designator on functional gas and bloating. Two more human trials exist on the same code. Being a single-strain product, the dose is unambiguous — the whole 2 billion is that organism.
That is the strongest structural argument this category can make for itself, and it comes at supermarket prices. It is also the reason the industry’s stock defence collapses: strain-level labelling is clearly not a luxury only premium brands can afford.
The problem is what surrounds the strain. Maltitol is the second ingredient, and each serving carries 3 g of inulin. Both are well-documented causes of exactly the gas and bloating this product sells relief from. The label knows it — the Suggested Use reads “If gas, bloating, or stomach upset occurs, reduce daily serving.”
One smaller finding worth keeping straight: the CFU basis is stated at expiry, on the label. It is absent from the product page. Read the website and you cannot learn it; hold the bottle and you can.
