Yes we have the senior kind. Last year we found a great vet, he accepts that I prefer alternative ways. One time he said I could try milk thistle and wanted to spell it for me :), of course I could tell him that I knew about it.
My MD is the same, I think I just lucked out. After my last test he told me to supplement with 1000IU's of vitamin D. It is amazing but I was on at least 6 prescription drugs for the rest of my life, so one day (after a year of liverflushing) told him I stopped them all, will you believe that he suggested some supplements I could use, like the ones we read about on CZ.
