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 →
200B CFU is above typical clinical range (10-100B) and dose-response plateaus (Ouwehand 2017). 15 unnamed strains + microencapsulation is reasonable; strain-specific benefits (e.g., L. rhamnosus GG) require identity disclosure, which is missing.
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.

Probiotics 200B CFU is a product from UpNourish, categorized under Gut health & digestive support in the Supplements vertical. It is scored on the Vyvata Scoring Framework — an independent 6-dimension rubric applied uniformly to every product Vyvata lists.
55/100 overall — Standard tier (50–69 band). Per-dimension breakdown: Formulation 60, Safety 60, Evidence 55, Manufacturing 55, Transparency 45, Sustainability 45. Scored as of 2026-08-24.
200B CFU is above typical clinical range (10-100B) and dose-response plateaus (Ouwehand 2017). 15 unnamed strains + microencapsulation is reasonable; strain-specific benefits (e.g., L. rhamnosus GG) require identity disclosure, which is missing.
Strongest: Formulation at 60/100 (dose adequacy, bioavailability form, and ingredient redundancy) and Safety at 60/100 (adverse-event profile, interaction risk, and dose ceiling). Weakest: Transparency at 45/100 (dose disclosure vs proprietary blends, and honesty of marketing claims) and Sustainability at 45/100 (sourcing practices, packaging, and corporate practice). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.
No third-party certifications (NSF, USP, ConsumerLab, or equivalent) were on record at the time of scoring. This affects the Manufacturing dimension score. The manufacturer may test internally or have obtained certification more recently — check the current product label for the most up-to-date information.

The Vyvata Scoring Framework rates every listed product 0–100 across six dimensions: Evidence, Formulation, Manufacturing, Safety, Transparency, and Sustainability. Tier bands: Elite 85–100 (top-tier evidence + formulation + manufacturing), Verified 70–84 (strong on most dimensions), Standard 50–69 (solid but with weaknesses called out), Rejected 0–49 (specific failures documented). Rejected products remain listed with reasons. Full methodology at https://vyvata.com/pages/methodology.
