Worth the cost
I always had this pain on the upper left side of my abdomen, but when I mentioned it to doctors, they pretty much ignored me. So I took matters into my own hands, and started taking acetyl-glutathione. Like magic, the constant pain was gone. I have taken it faithfully ever since. If I, for some reason, skip it for a week or so (traveling), the pain returns. My LFTs always return within normal limits, so I like that it is doing its job.
