I see a lot of people asking about Milk Thistle... its a topic im very familiar with.
DO NOT take MT as a means of 'supporting' your liver...or to 'help' it filter.
MT is a protector of the liver, it will BLOCK the liver from doing its job.
I know nothing about the Liv52,...may check into that one also, especially before i decide to start using.
I like NATURAL supplements...and a company called Standard Process is one that you can be sure is natural...or 'organic'.
They make a supplement called LiverPlex... heres some info on it...
