NusaPure Glucomannan 1,000 mg per Serving 200 VCaps (20:1 Extract, BioPerine Non-GMO, Vegan) Konjac Root

NusaPure Glucomannan 1,000 mg per Serving 200 VCaps (20:1 Extract, BioPerine Non-GMO, Vegan) Konjac Root 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.

55/100 overall — Standard tier (50–69 band). Per-dimension breakdown: Transparency 60, Evidence 55, Manufacturing 55, Safety 55, Sustainability 55, Formulation 48. Scored as of 2026-08-24.

Glucomannan is a soluble fiber from konjac root with EFSA-approved satiety and weight-management claim at 3g/day taken with water before meals. The formulation is a genuine problem here: glucomannan works via bulk viscosity, and a "20:1 extract" removes the fiber matrix that drives the mechanism — quality glucomannan products use whole konjac powder, not concentrated extracts. Serious safety concern: glucomannan capsules require large volumes of water and have caused esophageal obstruction (FDA warnings) — no label warning implied by title. Would need reformulation as whole-root powder or drink mix and choking-hazard labeling to reach Standard 62+.

Strongest: Transparency at 60/100 (dose disclosure vs proprietary blends, and honesty of marketing claims) and Evidence at 55/100 (quality of published RCT support for the active ingredients at the label dose). Weakest: Sustainability at 55/100 (sourcing practices, packaging, and corporate practice) and Formulation at 48/100 (dose adequacy, bioavailability form, and ingredient redundancy). 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.
