As far as raising glutathione, I get good results from the following daily combination: vitamin C, P5P, lysine, curcumin, whey protein, and selenium supplementation.
I agree that curcumin / turmeric is a fantastic supplement for many people with chronic viral infections, and is highly recommended - it not only is antiviral but helps to lower tnf-alpha
and also helps insofar as maintaining healthy levels of glutathione.
This is the specific supplement that I use with great benefit:

I take just one per day with food, and think that is all that is needed for most people. I take two days off per week, and one week off every two months.
