is Chitosan POSSIBLY SAFE for most people ?

Chitosan is POSSIBLY SAFE for most people when taken by mouth for up to six months or when applied to the skin. When taken by mouth, chitosan might cause mild stomach upset, constipation, or gas.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking chitosan by mouth if you are pregnant or breast-feeding. Stay on the safe side and avoid use.

Shellfish allergy: Chitosan is taken from the outer skeleton of shellfish. There is a concern that people with allergies to shellfish might also be allergic to chitosan. However, people who are allergic to shellfish are allergic to the meat, not the shell. So some experts believe that chitosan may not be a problem for people with shellfish allergy.
