I am a BCBA and state-accredited nutrition advisor working with a family with the following profile:
Mother is currently breastfeeding a 6-month-old boy who has recently started solids. His Organic Acids Test (OAT) shows elevated arabinose and low glutathione. His older brother has autism. The mother also has elevated arabinose on her own OAT.
Given the connection between low glutathione, oxidative stress, and neurodevelopmental risk — and given that NAC is a glutathione precursor — I am exploring whether maternal NAC supplementation during breastfeeding could support the infant's glutathione levels through breast milk transfer, alongside his introduction to solids.
My specific questions:
1. What is known about NAC transfer into breast milk when taken as a supplement by a breastfeeding mother?
2. What dose of NAC would be considered safe for this breastfeeding mother?
3. Is there any research on maternal NAC supplementation as a strategy to support infant glutathione in a high-risk neurodevelopmental context?
4. Given that the infant is now also eating solids, are there any glutathione-supporting foods or precursors that would be appropriate to introduce at this stage?
I am aware that published data on NAC and breast milk is very limited — but would welcome any clinical guidance your team can offer."
