I need some advice. I know that lots of folks on this board are much better informed than I am about herbs and supplements, and I'm confused. I've been taking freeze-dried milk thistle seed meal capsules for a while now, and they seem to have improved my liver function tests (up until recently). But because I had a very high result on my ALT and AST tests, my doctor had me repeat the tests today and may want me to have an ultrasound on my liver. All this made me look more closely at the milk thistle I've been taking--and do a little more research. Apparently, it's the sylymarin component of the capsules that is most important to liver health, and the capsules I've been taking average only 4% silymarin. On the other hand, I've seen ads for milk thistle extract with 80% silymarin. So which form of milk thistle is better--fresh, freeze-dried seed meal with only 4% silymarin or extract with 80% silymarin? Are there special benefits to taking the seed meal instead of the extract that would make up for the huge difference in the silymarin percentage? --Laura R.M.
