Head to head
Florastor Probiotic discloses more: 5 out of 6 against 4. That is a statement about Align Probiotic Pro Formula's label, not about the product.
| Criterion | Florastor Probiotic | Align Probiotic Pro Formula | Agreement |
|---|---|---|---|
| 1. Exact amount for every active ingredient No proprietary blend appears anywhere on the Supplement Facts panel. | 1 ✓ | 1 ✓ | same |
| 2. Standardization percentage stated Wherever potency depends on a percentage, such as % withanolides, the label states it. | 1 ✓ | 1 ✓ | same |
| 3. Chemical form or strain named “Magnesium glycinate,” not “magnesium.” For probiotics, every organism carries a strain designation. | 1 ✓ | 1 ✓ | same |
| 4. Dose within the trial range The disclosed dose falls inside the range human trials used for the outcome the product claims. | 1 ✓ | 0 ✗ | differ |
| 5. Certificate of analysis is public A third-party certificate is reachable with no email gate and no account. | 0 ✗ | 0 ✗ | same |
| 6. Per-serving amounts are complete Serving size and servings per container are both on the panel. | 1 ✓ | 1 ✓ | same |
| Disclosure score | 5/6 | 4/6 |
The pair splits on 1 of the six criteria. The reasoning below is the same text that appears on each product page.
Florastor Probiotic: Under methodology v1.12, the first product in the sample to take this point. The panel declares 500 mg of preparation rather than CFU, so the probiotic unit mismatch does not arise, and 500 mg falls at the floor of the 500-1000 mg/day range set by independent adult trials of this strain (Seddik 2019 PMID 30694338; Sjomina 2023 PMID 37942999; Salazar-Parra 2023 PMID 37400812). Maev 2025 excluded from setting the range under the independence rule: it dosed Enterol, a Biocodex product, and Biocodex manufactures Florastor. The outcome objection is published alongside the v1.12 ruling.
Align Probiotic Pro Formula: Under methodology v1.13. The panel declares 1x10^9 CFU at manufacture but guarantees only 1x10^7 through the best-by date, and the through-expiry figure governs. Whorwell 2006 (PMID 16863564, n=362) found 1x10^8 CFU significantly superior to placebo in capsule form while 1x10^6 and 1x10^10 were not, so the guaranteed dose is ten times below the only capsule dose shown to work. Note that the at-manufacture figure of 1x10^9 would have scored 1 under the benefit-of-the-doubt rule; the ruling and the objection to it are published in the methodology.
Both labels were scored the same way on the remaining 5.
Florastor Probiotic: The single active carries an exact amount, Saccharomyces boulardii CNCM I-745 500 mg. No proprietary blend on the panel.
Align Probiotic Pro Formula: The single active carries an exact amount, Bifidobacterium longum subsp. longum 35624 10 mg. No proprietary blend.
Florastor Probiotic: No standardization-dependent ingredient in the formula.
Align Probiotic Pro Formula: No standardization-dependent ingredient in the formula.
Florastor Probiotic: CNCM I-745 is a culture depositary designation (Collection Nationale de Cultures de Microorganismes), not a species name or a marketing name.
Align Probiotic Pro Formula: Strain designation 35624 is printed, not the species alone.
Florastor Probiotic: No publicly accessible third-party certificate of analysis located 2026-09-26. The search covered the 10 listing images, florastor.com navigation and footer (no Quality, Testing, Lab Results or Transparency link exists), the florastor.com FAQ page, and a site-scoped web search for 'certificate of analysis'. Recorded as a negative finding, not a claim that none exists.
Align Probiotic Pro Formula: No publicly accessible third-party certificate of analysis located 2026-09-27. Search covered the 12 listing images, alignprobiotics.com product and education pages, and a site-scoped web search for 'certificate of analysis'. The alignprobiotics.com footer could not be walked directly because the domain is blocked to this session's browser, so the brand-site leg of the search is weaker here than for other rows. Recorded as a negative finding, not a claim that none exists.
Florastor Probiotic: Serving size 2 capsules and servings per container 50 are both printed on the panel. First product in the sample to take this point.
Align Probiotic Pro Formula: Serving size 1 capsule and servings per container 63 are both printed on the panel.
