If you don't have proper glutathione production, I don't see how the body could fully recover. Same of any of the maladies that involve the immune system.
To restore glutathione, a key thing needed is to detox glyphosate. Because it's a glycine analogue, which takes glycine's place when it's put together to create glutathione. As an aside, you want to detox both glyphosate and aluminum together, because glyphosate is an aluminum transport, and makes aluminum go where it shouldn't be (e.g. your nervous system, brain).
So add both of those to your detox regime. A friend found that supplementing with liposomal glutathione in the mean time, helps with symptoms.
