NusaPure White Kidney Beans 30:1 Extract, 800 mg 200 Vegan Capsules - Bioperine - (Vegan, Non-GMO) is a product from NusaPure, categorized under Weight management & metabolic health 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 62, Formulation 52, Manufacturing 50, Transparency 48, Evidence 45, Sustainability 45. Scored as of 2026-08-24.

White kidney bean extract (Phaseolamin) marketed as a 'carb blocker' via alpha-amylase inhibition. Trial evidence is mixed and effect sizes are small (Barrett 2011 meta-analysis found modest weight-loss effect, but heterogeneous results). Below Standard because (1) carb-blocker marketing category has FDA-warning history for overpromising; (2) alpha-amylase % standardization not disclosed — the active phaseolamin can vary widely by extract source; (3) real-world clinical significance is modest even at studied doses. Would move to Standard 55+ with published phaseolamin standardization + honest positioning vs cited RCT effect sizes.

Strongest: Safety at 62/100 (adverse-event profile, interaction risk, and dose ceiling) and Formulation at 52/100 (dose adequacy, bioavailability form, and ingredient redundancy). Weakest: Evidence at 45/100 (quality of published RCT support for the active ingredients at the label dose) 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.

Would move to Standard 55+ with published phaseolamin standardization + honest positioning vs cited RCT effect sizes.
