Chitosan Oligosaccharide/Chitin

Chitosan is a water-soluble oligosaccharide product with a degree of polymerization between 2 and 20, which originates from marine organisms including shrimp and crab shells, and is the only positively charged parthenogenetic amino oligosaccharide. It has many advantages such as low molecularity, high water solubility, high biological activity, high bioavailability, etc. It helps to reduce human cholesterol and improve immunity.
