Our glucomannan powder is a highly purified, water-soluble dietary fiber extracted from the corm of Amorphophallus konjac (konjac root). With ≥95% glucomannan content, it delivers exceptional thickening, gelling, and water-binding capacity at extremely low use levels—making it one of the most efficient natural hydrocolloids available.
Unlike modified starches or synthetic gums, glucomannan is non-GMO, vegan, gluten-free, zero-calorie, and backed by clinical research for digestive health, weight management, and metabolic support.
Note: This product is distinct from whole konjac flour—it undergoes additional purification to remove residual proteins, ash, and odor compounds, resulting in a neutral-tasting, high-purity fiber ideal for sensitive applications like clear beverages or dietary supplements.
What Is Glucomannan?
Glucomannan is a high-molecular-weight polysaccharide composed of β-(1→4)-linked D-mannose and D-glucose units in a ~1.6:1 ratio. Its unique linear structure enables:
- Extreme water absorption (up to 200x its weight)
- Formation of viscous, non-gelling solutions in cold water
- Synergy with xanthan gum or carrageenan for elastic gels (with heat/alkali)
- Resistance to human digestive enzymes → 0 kcal/g
Our glucomannan powder is produced using food-grade water extraction and membrane filtration—without chemical solvents, bleaching agents, or sulfites.
Key Functional & Health Benefits
- Clinically Proven Satiety Aid: Swells in stomach, promoting fullness (EFSA & Health Canada approved claims)
- Cholesterol & Blood Sugar Support: Reduces postprandial glucose and LDL-C at 3–4 g/day
- Prebiotic Potential: Fermented by colonic microbiota to produce short-chain fatty acids
- Zero Calories & Net Carbs: Fully compliant with keto, paleo, and diabetic diets
- Ultra-High Viscosity: Effective at 0.1–0.5% usage levels
- Clean Label: Listed as “glucomannan” or “konjac fiber”
Usage Guidance: Always mix with at least 250 mL of water before consumption to prevent esophageal blockage. For food use, disperse in cold liquid before heating.

Pro Tip: For instant dispersion, blend glucomannan with sugar or maltodextrin before adding to liquids.
Why Choose Our Glucomannan Powder?
We source konjac from certified farms and use advanced purification to achieve >95% purity—significantly higher than standard konjac flour (typically 70–85%). This ensures consistent viscosity, minimal odor, and compliance with strict supplement and infant nutrition standards.
