Overview

Chitosan is a sugar that is obtained from the hard outer skeleton of shellfish, including crab, lobster, and shrimp. It is used for medicine.

Chitosan is used for high blood pressure, high cholesterol, obesity, wound healing, and other conditions, but there is little scientific evidence to support many of its uses.

In pharmaceutical manufacturing, chitosan is used as a filler in tablets, to improve the way certain drugs dissolve, and to mask bitter tastes. It is also used to help make foods last longer.

How does it work ?

Chitosan is extracted from the shells of shrimp, lobster, and crabs. It is a fibrous substance that might block absorption of dietary fat and cholesterol. When used on wounds, chitosan helps blood to clot.
