I have had a few patients wanting to know if they could take Chitosol as a fiber supplement.

I am currently working as an outpatient dietitian. I recently have had a few patients wanting to know if they could take Chitosol as a fiber supplement. I advised against it for a variety of reasons. I just wanted to get your opinion on this product. Thank you.

I checked several over the counted medication drug information websites and could not find any information about Chitosol.

Chitosan, a binding resin, is a dietary supplement that claims weight loss which is unfounded since it can’t be replicated in humans even though it precipitates fat in a petri dish. Chitosan is made from the skeleton of shrimp, crab, and other shellfish. It is undigested as it goes through the body but does not provide the usual benefits of fiber found in whole grains, fruits, vegetables and cooked dried beans or peas.
