Chitosan is a botanical extract derived from Deacetylated chitin from crustacean shells, standardized to Chitosan (pure). With CAS registry number 9012-76-4, this ingredient belongs to the Carb & Fat Absorption Blockers category of weight management actives. Cationic polysaccharide binds negatively charged dietary fats (triglycerides, fatty acids, bile acids) through electrostatic interaction in stomach. Fat-chitosan complex is indigestible → reduces fat calorie absorption 5-10%. Also binds bile acids → liver produces new bile from cholesterol → additional LDL reduction. As a B2B manufacturer, Shaanxi Baisifu Biological Engineering Co., Ltd. supplies Chitosan in bulk quantities with full Certificate of Analysis (COA), ensuring consistent Chitosan (pure) content and regulatory compliance for dietary supplement, functional food, and nutraceutical applications.
Standard specifications for Chitosan bulk supply from Baisifu:
Cationic polysaccharide binds negatively charged dietary fats (triglycerides, fatty acids, bile acids) through electrostatic interaction in stomach. Fat-chitosan complex is indigestible → reduces fat calorie absorption 5-10%. Also binds bile acids → liver produces new bile from cholesterol → additional LDL reduction.
Level II. Meta-analyses show 1-2 kg weight loss over 4-12 weeks and 5-10% LDL reduction. Fat-binding proportional to dietary fat intake. Gallaher et al. showed chitosan+ascorbic acid enhanced fat binding by 50%.
⚠Shellfish allergy concern (derived from crustacean shells). High-quality ≥85% deacetylation has minimal protein but severe allergy individuals should avoid. Plant-derived fungal chitosan alternatives available (more expensive). May reduce fat-soluble vitamin absorption.

Q1: Can shellfish allergy sufferers use Chitosan?
High-quality chitosan has minimal protein, but severe allergy individuals should avoid. Plant-derived fungal chitosan alternatives available for allergy-sensitive markets.
Q2: Why combine with Vitamin C?
Ascorbic acid prevents chitosan aggregation in stomach, maintaining dispersed state that increases fat-binding surface area by ~50%. Well-documented synergistic effect.
Q3: Effective on low-fat diet?
Effect proportional to dietary fat consumed. Minimal benefit on <30 g fat/day. Designed for moderate-to-high fat diets.
For complementary weight management formulations, consider combining Chitosan with: Konjac Glucomannan, Garcinia Cambogia Extract, Lotus Leaf Extract, Green Coffee Bean Extract. Multi-ingredient stacks targeting different mechanisms (lipase inhibition, AMPK activation, thermogenesis, appetite suppression) produce synergistic effects superior to single-ingredient products.
