# konjac.bio > A topic site about konjac (Amorphophallus konjac): the plant, food applications, glucomannan supplements, skincare, and B2B sourcing. Built for buyers, formulators, and curious consumers who want evidence-based answers without marketing fluff. ## What konjac is Konjac is a perennial root crop native to East and Southeast Asia. Its underground corm yields konjac flour and konjac glucomannan (KGM), a water-soluble dietary fiber prized for its viscosity. Konjac is the source of shirataki noodles, konnyaku jelly, konjac rice, konjac sponges, and many supplement formats. ## Content structure - /pillars/ hub pages for each major konjac topic (18 total): shirataki noodles, glucomannan supplements, konjac jelly, recipes, sponges, rice, keto and weight loss, flour, cultivation, snacks, comparisons, wholesale, safety, gum, cholesterol, diabetes, skincare. - /clusters/ ~144 deep-dive answer pages targeting specific buyer questions (one cluster per query). - /guides/ buyer guides for formulators and brand owners (sourcing, specifications, COA reading, choking-hazard compliance, MOQ negotiation). - /faq/ cross-topic frequently asked questions. - /glossary/ konjac and glucomannan terminology. - /about/ what konjac.bio is and editorial standards. - /contact/ general inquiry and B2B sourcing form. ## Sourcing standpoint konjac.bio is published by an industrial-enzymes and food-ingredients team. We do not sell consumer products. We supply konjac glucomannan, konjac flour, and konjac-based ingredients to manufacturers, supplement brands, foodservice operators, and private-label projects. All content references peer-reviewed studies, EFSA opinions, FDA notices, and USDA data where available. ## Editorial principles - Evidence-linked: every health claim cites the underlying source. - Buyer-honest: we name tradeoffs (taste, texture, cost, regulatory caveats) instead of glossing over them. - Hazard-aware: choking-risk advisories around mini-cup konjac gel candies are referenced wherever relevant. - Not medical advice: nothing here is intended to diagnose, treat, cure, or prevent disease.
