Jeff Huseby says, "do we know what an upregulated GGT gene does to glutathione status?"
Well, if you assume that whatever the genetic test told you is actually happening
as increased GGT activity, then what it should do is break down blood glutathione and help the
breakdown products get into the cell to increase intracellular glutathione. I think
as to what it does to glutathione status measured in the blood, I don't know. Because
on the one hand, it's probably going to break down glutathione in the blood. But in general,
if you're improving glutathione status inside the cell in the liver, you're going to increase
the export of glutathione. So I'm not sure if it would change glutathione status at all.
It probably would improve glutathione status of cells that lack glutathione transporters,
which would be a good thing, but I can't see this doing anything bad, but I'm not sure if
it would cause a measurable difference in your glutathione status as measured in the blood.
