Chitosan

Safe product and/or breastfeeding is the best option.

Polysaccharide composed of glucosamine and N-acetylglucosamine polymers derived from the deacetylation of chitin from the exoskeleton of crustaceans. It has multiple industrial, agricultural, veterinary and biomedical applications. It is used as a dietary supplement in preparations for obesity and hypercholesterolaemia.

At the time of the last update, we found no published data on its excretion in breast milk.

Its very high molecular weight (200,000 to 1 million daltons) makes its passage into breast milk highly unlikely.

This product is non-toxic. AESAN recommends a maximum daily intake of 3 g with the warning that "excessive consumption may cause intestinal discomfort". (AESAN 2012)

There is little scientific evidence of its effectiveness as a lipid-lowering or weight-loss agent (Shahinfar 2023, Bonetti 2022, Medline 2019, Jull 2008, Mhurchu 2005). A low-calorie diet and moderate exercise are preferable.

Alternatives

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.
