start low (50 mg) and increase by ~25 mg weekly as tolerated
Since redox processes in the cell are highly regulated, the presence of glutathione in the periplasm at such high levels strongly indicates that this molecule also plays a role in the redox homeostasis of the periplasm, similar to its role in the ER (Birk et al., 2013
Existing safety data is reassuring for supervised, cyclical use, but long-term continuous administration without professional oversight isnt something any reputable clinic would recommend
