    9,3 grams of NAC seems like a lot. Also NAC has pro-oxidant effects at high doses. Considering that a dosage above 1,2 grams pr. day can cause headache, nausea, abdominal pain, vomiting, constipation, and diarrhea, 9.3 seems way too much. There must be safer ways to raise glutathione.

      That’s a fair point, and also, it’s unknown how the longer-term effects (>25 weeks) of those doses would impact health. But, if those doses were bad for health in the shorter-term, one would expect worse biomarkers, but in fact, the opposite was true.
