Chitosan is a polysaccharide derived from the shells of crustaceans that can bind to fat and cholesterol in the digestive tract, helping to maintain cholesterol levels already within healthy range. Now Chitosan features LipoSan Ultra, a high-density form of Chitosan that, in laboratory testing, binds up to five times more fat than conventional Chitosan. A study has demonstrated that LipoSan Ultra may aid in supporting a healthy body weight. Chromium, a mineral essential for normal glucose metabolism, has been included to complete this formula.
