Konjac Glucomannan is a botanical extract derived from Amorphophallus konjac tuber, standardized to Glucomannan fiber. With CAS registry number 37220-17-0, this ingredient belongs to the Carb & Fat Absorption Blockers category of weight management actives. Glucomannan absorbs 50× its dry weight in water, forming viscous gel in stomach: (1) Physical gastric fullness → reduces calorie intake 10-20%; (2) Delays gastric emptying → prolonged satiety; (3) Envelopes carbs/fats → slows absorption; (4) Binds bile acids → reduces LDL cholesterol reabsorption. FDA approved health claim for cholesterol. As a B2B manufacturer, Shaanxi Baisifu Biological Engineering Co., Ltd. supplies Konjac Glucomannan in bulk quantities with full Certificate of Analysis (COA), ensuring consistent Glucomannan fiber content and regulatory compliance for dietary supplement, functional food, and nutraceutical applications.

Level I. FDA approved health claim for cholesterol. Onakpoya et al. (2014) meta-analysis found 0.64 kg weight loss over 5 weeks. Effect modest but reliable. Best combined with other ingredients.
⚠ Choking hazard for tablets — FDA warning after esophageal obstruction incidents. Capsule/powder strongly preferred. Take with ≥250 mL water per dose. May reduce medication absorption — take meds 1 hour before or 4 hours after. Flatulence common initially.

• Heavy metals, microbial, moisture compliance
• Pesticide residue testing (where applicable)
• Stability data and shelf life confirmation Available forms: powder extract, oil-based softgel fill, microencapsulated powder
Minimum order: 1 kg (sample quantities available)
Lead time: 7–15 business days
Packaging: 25 kg/drum, double-layer PE bag + fiber drum, nitrogen flush available
Q1: Why capsule form over tablets?
Tablets can swell in esophagus before reaching stomach — choking hazard. FDA documented serious incidents. Capsules/powder dissolve safely in stomach.
Q2: How much water with glucomannan?
≥250 mL per 1 g dose. Without adequate water, fiber cannot hydrate and may cause GI obstruction.
Q3: Can combine with other weight-loss extracts?
Yes — glucomannan provides satiety/fiber component while other extracts (green tea, garcinia) provide metabolic enhancement. Most commercially successful B2B formula strategy.
For complementary weight management formulations, consider combining Konjac Glucomannan with: Chitosan, Garcinia Cambogia Extract, Green Tea Extract, Gymnema Sylvestre Extract. Multi-ingredient stacks targeting different mechanisms (lipase inhibition, AMPK activation, thermogenesis, appetite suppression) produce synergistic effects superior to single-ingredient products.
