im unable to comment on your AST values, but i did want to say that almost every piece of credible literature ive read says that the amount of milk thistle required to produce any significant results is not offered in the recommended dosings generally accepted. iow, you would have to down half that bottle to get any real effect from it. and for this reason i have switched up to UDCA which has solids proven medical results available on the net.
i have not use Liv52.
not trying to tell you what to take but simply wanted to share my experience and opinion, fwiw
