Umm... no personal experience using it myself. I feel almost silly mentioning this
, but I do have experience with its veterinary use. My vet has my older dog on it (in compound with SamE which is also reported to be good for the liver). Her tests show a key liver enzyme (I'm assuming the doggy version of ALT) to be elevating. It has definately improved her energy level
, but she has actually gained weight on it (which is a good thing for her). The way it was described to me, her liver is now able to process her food and less goes to, um, well, waste.
OK, sorry, I know that this is a people forum and not an animal one, and I hope I don't offend by relating my non-people related experience. I just thought you might want to know that (at least in a different species) it had the opposite effect of causing weight loss.
Another thought - Do you have threatened liver function? Like mandalinn82 said, I don't know that its supposed to do much if your liver is within normal ranges.
Hope this was helpful!
