Chitosan is a type of fiber made from chitin found in shellfish. One form is used industrially to remove oil from water and even to clean oil spills. In a dietary supplement form it also has oil and fat binding properties to control blood lipid levels and supports healthy stool formation. The specialized Chitosan from Natural Balance is denser and more soluble, resulting in more effective binding to fat in your diet. If you're looking to lose weight and or just want to maintain healthy fat levels, Natural Balance Chitosan can help.
