I'm thinking about switching from Denamarin to Denosyl/Vetri-DMG and Hepatosupport. However, I'm a little confused on if I need to supplement with Vitamin E as well. I know hepatosupport has more B vitamins than the denamarin, however does it have vitamin E as well. I'm a little confused and trying to switch since the Denamarin seems to make Mayme's stomach hurt so much. Also - I know the yahoo group recommends the Vetri-DMG, but I don't see anywhere where that product helps the liver.
