My kitty was taking Denamarin when he had fatty liver. It contains Milk Thistle and Sam-E which help the liver heal. Supporting a liver that is sick is the only thing I have heard of giving it for. Unless it was a coincidence, I think it helped bring his liver numbers back down to normal range.
I just picked up a script today for Obi, who has liver issues. The vet says he will be on it indefinitely. Its about $1 a day. Does anyone know the equivalent doses in SamE and milk thistle?
