Head to head
Align Probiotic Pro Formula discloses more: 4 out of 6 against 3. That is a statement about Culturelle Pro Strength Probiotics's label, not about the product.
| Criterion | Culturelle Pro Strength Probiotics | 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. | 0 ✗ | 0 ✗ | same |
| 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. | 0 ✗ | 1 ✓ | differ |
| Disclosure score | 3/6 | 4/6 |
The pair splits on 1 of the six criteria. The reasoning below is the same text that appears on each product page.
Culturelle Pro Strength Probiotics: Serving size 'One (1) Capsule' is stated but servings per container is absent from the Supplement Facts panel, the same failure as Seed DS-01.
Align Probiotic Pro Formula: Serving size 1 capsule and servings per container 63 are both printed on the panel.
Both labels were scored the same way on the remaining 5.
Culturelle Pro Strength Probiotics: Both actives carry exact amounts, Lactobacillus rhamnosus GG 46 mg (12 billion CFUs) and Inulin (Chicory Root Extract) 200 mg. No proprietary blend on the panel. First product in the set to take this point.
Align Probiotic Pro Formula: The single active carries an exact amount, Bifidobacterium longum subsp. longum 35624 10 mg. No proprietary blend.
Culturelle Pro Strength Probiotics: No standardization-dependent ingredient. The probiotic is CFU-declared and inulin is named as the compound with its source in parentheses, so the quantified item is the inulin, not an extract of graded purity. This is the distinction from BIOMA, where the label declared 100 mg of corn cob extract rather than a stated XOS weight.
Align Probiotic Pro Formula: No standardization-dependent ingredient in the formula.
Culturelle Pro Strength Probiotics: Strain designation present (rhamnosus GG), and inulin is a defined compound with its source named.
Align Probiotic Pro Formula: Strain designation 35624 is printed, not the species alone.
Culturelle Pro Strength Probiotics: Inulin 200 mg against an independent reference range of 12 g/d for functional constipation (Puhlmann 2025, PMID 41233756), roughly sixty times below the studied dose. Probiotics excluded per methodology.
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.
Culturelle Pro Strength Probiotics: No publicly accessible third-party certificate of analysis located 2026-09-26 (product page images, culturelle.com, site-scoped search, open web search); 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.
