Everything Vyvata knows about this product — the score, the evidence, the FAQ, and where else to find shopper reviews. No hidden data. Every vendor is scored on the same published rubric — no brand can pay for placement. Read the rubric →
Advanced Daily Probiotic markets to women for gut + vaginal microbiome + UTI + immune support — a broad four-target claim set. Probiotics for vaginal microbiome and UTI prevention have moderate evidence for specific Lactobacillus strains (L. rhamnosus GR-1, L. reuteri RC-14 per Beerepoot 2012 and Reid 2013 for recurrent UTIs), but strain identity and CFU count at ship time are the make-or-break variables. The visible description does not list strains, CFU counts, or delivery mechanism (delayed-release capsules protecting against stomach acid). Without strain-level disclosure, a probiotic product cannot be evaluated for the specific clinical claims it makes. The 'UTI support' claim edges toward medical-treatment language. Not on strict auto-fail for medical claim (technically structure/function), but the evidence-to-claim gap and transparency gap keep it in Rejected. Also 'Advanced Daily Probiotic' as a name is generic.
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

The Vyvata score measures product integrity against a published rubric, not customer sentiment. Vyvata does not aggregate, republish, or license third-party reviews — the links below open search pages on their respective platforms.
Every VSF-related metafield surfaced verbatim. Nothing hidden. If you spot data that looks wrong, let us know.
Every score is set from the published rubric, audit-logged, and rescored whenever new evidence emerges (published trials, updated labels, third-party testing releases). Every vendor is scored on the same criteria — no pay-to-play. See our editorial-independence disclosure for the full policy, including brands with an editorial relationship to this site.
