Chitosan is a natural biopolymer derived from chitin, which is found in the shells of crustaceans like shrimp and crabs. It is a white, odorless powder that is often used in various applications, including food preservation, water purification, and as a dietary supplement. Due to its unique properties, Chitosan can help reduce fat absorption in the body and promote weight loss, making it popular among health-conscious individuals. In addition to its health benefits, Chitosan is also environmentally friendly. It is biodegradable and non-toxic, making it a sustainable alternative to synthetic materials. Researchers are exploring its potential in fields like medicine and agriculture, where it may help improve soil health and support plant growth.
