A substance made from chitin, often used in dietary supplements to help reduce fat absorption.
Chitosan is often marketed as a weight loss supplement due to its ability to bind fat in the digestive system.
Chitosan is derived from "chitin" (from Greek "chiton", meaning covering or shell) and the suffix "-san" (from Japanese, meaning a substance). Chitosan refers to a substance derived from the shell of crustaceans, which is a modified form of chitin.
Think of 'chitin' as the 'covering' or 'shell' of crustaceans, and remember that 'chitosan' is a substance made from that shell.
