I believe the new Metamucil capsules have calcium in them. That is the only one I've seen with calcium carbonate. Perhaps there are others, but it is the most popular brand name I've seen with it.Definitely stick around and read the forums... The "find" feature is a great tool. I search for things such as "Remeron" and these issues can be found discussed years back... It's nice, people are friendly, and can relate to what you're going through.Hope you start feeling better soon, I know how bad this thing sucks
