Is Chitosan compatible with breastfeeding? Do we have alternatives for Chitosan?


February 22, 2016 (Very Low Risk)

Polysaccharide polymers composed of glucosamine and N-acetylglucosamine which are derived from chitin deacetylation of the exoskeleton of crustaceans
with a molecular weight of 200,000 to over one million daltons and
many industrial, agricultural, veterinary and biomedical uses.

At latest update no published data on excretion into breast milk were found.
Its high molecular weight makes any passage through breast milk very unlikely.
Product which is devoid of toxicity.

Controlled studies have failed to prove its effectiveness as lipid-lowering or slimming enhancer.
Intake of reduced calorie diets and moderate exercising are accepted as more effective.
