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 →
Women-targeted probiotics are a legitimate category with some strain-specific evidence: Lactobacillus rhamnosus GR-1 and L. reuteri RC-14 (Urex/Fem-Dophilus) have real trial data for urogenital and vaginal microbiome support (Reid 2003, Petricevic 2008). But a scored probiotic evaluation requires (a) strain identification at the sub-species level with CFU counts, (b) shelf-stability data, and (c) delivery-form clarification (enteric-coated to survive stomach acid vs bare capsule). This SKU discloses none of these — 'Probiotic Extract Capsules' without strain, CFU, or delivery-form information. Additionally, 'probiotic extract' is a nonsensical phrase — probiotics are live bacteria; an 'extract' would be dead bacteria (paraprobiotics or postbiotics), which have separate but weaker evidence. Autofailed under proprietary_blend_hides_dose: undisclosed strains + undisclosed CFU + confusing 'extract' language makes verification impossible. Rejected at 45.
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.
