How Chitosan Is Effective for Weight Management

Chitosan was first discovered to have beneficial properties back in the 1980s. It has primarily been used in the nutraceutical industry and has been developed into functional foods, dietary supplements and herbal or natural products.

Chitosan has proven effective across multiple industries, including as a weight management supplement. As it is a naturally fibrous biopolymer, it can actively absorb oils, fats and lipids – up to 100 times its weight! This makes it an excellent option for assisting with the treatment of obesity, cholesterol, and other related diseases and conditions.  

Chitosan has been approved by the US Food and Drug Administration as a safe food additive, dietary fiber, and functional ingredient for consumer use.  As chitosan manufacturers with over 20 years of experience and a state-of-the-art chitosan factory, we offer only high-quality, pure chitosan in many formats, including chitosan powder. 

Chitosan and its derivatives, like pure chitosan powder, can have multiple applications, thanks to chitosan's unique properties and bioactivities. Let's take a closer look.

Chitosan properties and bioactivities: 

  • Antimicrobial  
  • Antioxidant 
  • Fat-binding  
  • Prebiotic 
  • Anti-inflammatory 
  • Anti-carcinogenic 
  • Antiulcer  

Weight management 

Obesity is a well-established risk factor for cardiovascular disease, diabetes, hyperlipidaemia, hypertension, osteoarthritis, and strokes. Considering current scientific knowledge and population needs, it appears tactical to provide weight management solutions to tackle the obesity epidemic while promoting calorie restriction to enhance overall wellness. 

Chitosan has nutraceutical properties, including antibacterial, anti-inflammatory, antioxidant, anti-carcinogenic and antiulcer bioactivities, including its application as a dietary fiber with fat-binding qualities. Chitosan and its derivatives have been shown to lower cholesterol by blocking the absorption of dietary fat and cholesterols. They can also facilitate weight and body fat reduction in humans, subsequently lowering systolic and diastolic blood pressure. Chitosan and its derivatives, like chitosan powder, is also a valuable prebiotic, promoting colonic conditions. 


Primex ChitoClear® chitosan 

Chitosan is a versatile, natural biopolymer that has found a variety of applications in all areas of the food sciences. Chitosan has many intrinsic nutritional values, such as antioxidant properties and health-promoting bioactivities against many chronic diseases, including hypercholesterolemia, hypertension, inflammation, immune diseases, etc.  

In addition, chitosan has excellent emulsifying properties and is used to stabilize various oil-in-water emulsions to avoid the use of synthetic surfactants. The intrinsic properties vary with the molecular weight (MW) and degree of deacetylation (DDA), which are the most important characteristics of chitosan. Indeed, chitosan can be used at low concentration in the food industry for its various functional properties, but its main application has been in the dietary supplement market. 

A recent study assessed the selective fat-binding capacity of ChitoClear® chitosan to different fat types, monitoring fatty acid absorption, neutral sterol and bile acid excretion in guinea pigs, a suitable animal model due to its similarities with human lipid metabolism. This is significant, as different fat types have different metabolism in animals and humans. The results show that ChitoClear® chitosan selectively reduces fat absorption and has a higher affinity to binding fatty acids with higher polarity.
