Brief summary
Chitosan is a natural polysaccharide of β-1,4-linked glucosamine residues deriving from chitin, a dietary fiber primarily obtained from fungal cell walls and the exoskeletons of various crustaceans (e.g. crab, lobster, and shrimp) and whose cholesterol-lowering properties are due to the hydrophobic bonds it forms with cholesterol and other sterols, interfering with the emulsification process in the intestine. In addition to reducing low-density lipoprotein cholesterol (LDL-C) levels, several studies showed that chitosan administration may help reduce body weight. For this reason, its use might be particularly useful as a strategy to simultaneously control two different risk factors for the development of CVDs.
Interventions
140 mg chitosan, 460 mg cellulose and 35.384 mg ascorbic acid for 1 tablet Oral administration: 3 tablets twice a day before the main meals
