At present, chitosan tablets are commercially available as over-the-counter dietary supplements for hypercholesterolemia and
overweight. Nevertheless, their formulation is primitive because the chitosan used is not in the most suitable physical and
biochemical form. Thus the consumers are forced to take large daily doses, and face exceedingly high costs and poor results.
Moreover for celiac disease, no dietary food incorporating chitosan exists. These kinds of patients have to use expensive glutenfree
dietary foods instead of bread and pasta, with economical, nutritional and psychological distress: all these inconveniences
could be removed by a proper incorporation of chitosan. Finally it is likely (but not yet investigated) that colitis patients might
have benefits from chitosan intake, chitosan being a carrier for colitis-specific drugs.
