Yeast and candida defense blend

Yeast and candida defense blend is a product from NYC Herbs®, 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.

48/100 overall — Rejected tier (0–49 band). Per-dimension breakdown: Safety 55, Sustainability 55, Formulation 50, Manufacturing 48, Evidence 40, Transparency 40. Scored as of 2026-08-24.

'Yeast and candida defense' is a category where 'systemic candida' is largely not a validated diagnosis outside of immunocompromised patients — mainstream medicine treats it as functional-medicine speculation. Products are typically multi-herb proprietary blends (pau d'arco, oregano oil, caprylic acid, etc.) without per-active mg disclosure. NYC Herbs is a small brand with no visible clinical data. Would move to Standard 55 if reformulated as evidence-based gut-support with disclosed per-ingredient doses.

Strongest: Safety at 55/100 (adverse-event profile, interaction risk, and dose ceiling) and Sustainability at 55/100 (sourcing practices, packaging, and corporate practice). Weakest: Evidence at 40/100 (quality of published RCT support for the active ingredients at the label dose) and Transparency at 40/100 (dose disclosure vs proprietary blends, and honesty of marketing claims). 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.

This product triggered the Vyvata auto-fail rule "proprietary_blend_hides_dose", which places it in the Rejected tier regardless of its scores on other dimensions. See the full explanation above and the methodology page for the current list of auto-fail rules.

Would move to Standard 55 if reformulated as evidence-based gut-support with disclosed per-ingredient doses.

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.
