Opitac The researchers behind a 2014 in vivo/ex vivo study on mice found that 10mg of Opitac-branded glutathione (around 80mg for an 80kg/176lb human) could be transported across epithelial cells in the intestines
The occurrence of ferroptosis in mature erythrocytes has not been confirmed and it seems quite challenging, since ferroptosis studies suffer from the lack of well-established markers and evaluation of this cell death requires a complex approach with identification of typical cellular and subcellular morphological alterations, genetic hallmarks, biochemical changes, expression of certain ferroptosis-related proteins, etc
To expound further on the previous question, most of these biomarkers are modulated by glutathione and its precursors at the mitochondrial level
In vitro studies have quantified this bioavailability
