Safe substance and/or breastfeeding is the best option.

Amino-monosaccharide that is a component of chitin, mucopolysaccharides and mucoproteins which is synthesized naturally in the body, found in cartilage, tendons and ligaments. Very abundant in seafood. It is used, without clearly scientific evidence of its efficacy, as an adjuvant treatment of osteoarthritis. (Rozendaal 2008)

N-acetylglucosamine is a derivative of glucosamine which is found naturally in breast milk. (Gudiel 2001, Miller 1994)

At latest update published were not found data on excretion in breast milk.

Its low bioavailability and rapid disappearance of the plasma stream makes it unlikely the pass into milk in significant amounts. It is a natural product with a very low toxic potential.

Expert authors consider the use of this medication safe during breastfeeding. (LactMed, Hale, Briggs 2015) 

The maximum daily amount of glucosamine as a food supplement should not exceed 500 mg. (AESAN 2011)


We do not have alternatives for Glucosamine since it is relatively safe.

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.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

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.

Thank you for helping to protect and promote breastfeeding.
