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.
