Here's an honest assessment
Without the scientific issue of whether or not GSH was absorbed intact and biologically active being resolved, we often relied on proven indirect methods that included supplements that contained one or more of the GSH precursors and antioxidant supplements which help spare GSH by reducing the level of free radicals

We found that HDL cholesterol and LDL cholesterol levels were higher and HbA1c levels lower in ALT responders than in non-responders
In the skin, S100A2 is co-localized with cytokeratin K14, an intermediate filament protein expressed primarily in basal proliferative KCs
Based on the impact of PfK13 mutations on hemoglobin uptake and GSH levels in the parasite, one can hypothesise that a decrease in redox-active ferrous heme in artemisinin resistant parasites leads to elevated GSH within the cell, potentially making them more tolerant to artemisinin-induced oxidative stress
