Methylsulfonylmethane (MSM) is an organosulfur compound, a product of the oxidation of dimethylsulfoxide (DMSO). Found naturally in plants, animals, and humans (MedlinePlus 2020).
It is used, without clear evidence of its efficacy (Liu 2021, Notarnicola 2011, Brien 2011) in the treatment of osteoarticular pain and as a nutritional supplement. It is also used as a solvent in industry.
Oral or topical cutaneous administration.
At the date of the last update, there was no available published data on its excretion in breast milk.
The scarce available pharmacokinetic data about it does not allow prediction on its excretion in breast milk.
Given the null published toxicity, moderate use would be compatible with breastfeeding.
We do not have alternatives for Methylsulphonylmethane (MSM).
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.
Thank you for helping to protect and promote breastfeeding.
