I've used this product for two things;
2.)Alcoholic liver protection
When I was on ph, I never once had any sort of liver or back pain, and I tend to think that because my liver was efficiently metabolizing the ph out of my system, it wasn't staying in long enough to give me bad side effects.
I've heard horror stories about gut/liver pains on ph, and I'm glad to have avoided it.
As to my, *ahem* secondary usage, whenever I knew I was going to be sending some alcohol my liver's way, I took a few tabs of this, and felt better about it.
Whether or not it's protecting me... we'll see in a few decades. But the science is there, and it cant hurt.
The only really bad thing I have to say about this product besides the smell (which isn't thaaaaat bad) is that it was a tad bit expensive where I got them. You've just got to remember the benefits, and shell out the dough.
