Glutathione & Breastfeeding

[Trying4two]

Thank you! I'd seen someone mention taking it through an IV, so I guess that explains why.

Below I copied this out of a paper about antioxidants. Basically glutathione is almost completely UNABSORBED orally. It is rapidly metabolized in the GI tract.

I don't think it worth the effort to take it orally.

Researchers suggest that GSH is poorly absorbed by oral route mainly due to the action of an intestinal enzyme, the γ-glutamyl transpeptidase (GGT) which degrades GSH[16] ([url]https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4536296/#bib16[/url]). Several studies showed that GSH supplementation in animals is effective, with benefits in the enhancement of immune function[17] ([url]https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4536296/#bib17);[/url] protection against the carcinogenesis process[18] ([url]https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4536296/#bib18);[/url] and improvement of the elimination of toxic chemicals[19] ([url]https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4536296/#bib19[/url]).

However, in humans, the effectiveness of an oral supplementation with GSH is very controversial. A number of studies were conducted but using intravenous or nebulized GSH. The results of studies conducted with oral GSH are mixed [20,21] ([url]https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4536296/#bib20[/url]). This differential absorption of oral GSH between humans and rats/mice could be explained by a difference in quantity and activity of the intestinal GGT enzyme [21] ([url]https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4536296/#bib21[/url]).

Although oral GSH appears to be the most convenient and safe way to take GSH, the lack of efficacy explains why this form is not often used in clinical trials.

I was wondering if I could take Glutathione while breastfeeding my 17 month old.
He is currently breastfeeding throughout the day. I would guess maybe 16 oz?
I would be taking it for egg quality, based on "Review on the role of glutathione on oxidative stress and infertility" from NCBI

Thank you!
