What is Chitosan?
Chitosan, scientifically known as Polyacetyl-glucosamine, is a polysaccharide derived from the shells of crustaceans such as shrimp and crabs. It is classified as a dietary fiber and is commonly used as an ingredient in various supplement formulations. Chitosan is typically found in products marketed for weight management, cholesterol control, and joint health. Its unique molecular structure allows it to interact with certain dietary components, making it a popular choice in supplements targeting these areas. Formulators often incorporate chitosan in capsules, tablets, and powders.
