hello! thought Id share my experiences with calcium carb. with you. I first read that taking calcium supplements helped with ibs d, so, thinking all calcium was created equal...i bought one which had calcuim, vitd and magnesium...eek big mistake, i later found out that mag is super bad for D. (it cleans you out--more so)
so than i went and bought some w/out the magnesium, I took it for a few days, and it seamed to "plug" me up...which i thought was great! until 2 days later it all seamed to EXPLODE out of me (worse than any other D episode) so I had give up on calcium being the answer for me, until recently, i started taking all my vitamins again (not related to the IBS-just as part of a "healthier" lifestyle) and I noticed that I had gone a whole week w/out a D episode...which never happens.. i thought maybe because I was eating healthier...but then the next week i went back to eating crap..stuff that always triggers my ibs...(not on purpose..im just a super bad dieter...hee hee) but still no ibs flare ups..how strange...then on week three I happened to be reading hte calcium bottle as I was taking some, and it is straight calcium...cheapie brand...no vitamin d, no magnesium..nothing but calcium carbonate. (which is bad for other people since you need vit d to absorb any of the calcium) but it is super for me! i havent had any "D" for almost a month now!! i guess the moral of the story is....dont give up on calcium...try a few different kinds, different brands, different doses etc. I take 2 a day at night before bed (used to have really bad d always in the mornings) hope this info is helpful!
