Chitosan is a supplement commonly extracted from the shells of crustaceans, such as shrimp and crab. Like dietary fiber, chitosan is not digestible but may have beneficial effects on the gastrointestinal tract. Chitosan may reduce the absorption of bile acids or cholesterol, either of which may cause a lowering of blood cholesterol. This effect has been repeatedly demonstrated in animals, and a preliminary human study showed that 3-6g of chitosan per day, taken for two weeks resulted in a 6% drop in cholesterol and a 10% increase in HDL (the good) cholesterol. This discovery is history in the making! Now weight conscious individuals may be able to have their cake and eat it too!
