calcium supplement side effects

Hi-just wondering if anybody else out there has had this problem. I am 1 year post diagnosis and so far no recurrence :)! I have recently added a calcium citrate + D supplement (no magnesium) at the urging of the gyn. Right after I started it, I had increased BM's and looseness; this had been really improving, so it is aggravating to say the least. I have looked online and calcium and magnesium supplements seem to be the usual culprits. Any comments? Anybody else out there had this happen? Thanks

I believe the usual side effect regarding bowel issues and calcium is constipation, which would be the opposite of what you are experiencing. Your issues could be caused by something else. The only way to know if the calcium is the culprit or not would be to stop taking it for a period of time and monitoring what happens.

LOOOONG before any diagnosis of anal cancer I had a problem with some calcium supplements. Some of them caused diarrhea and some didn't. Caltrate 600-D plus was the brand that worked best for me.

I had this problem a bit also until I started taking the Viactiv Calcium chews (or Walgreens brand) They are calcium with Vit. D and K. The recommended amount is 3 per day, so I just eat them throughout the day, also kind of a treat because its like candy that I justify as good for you. They were also rated highly in a recent report I read as calcium that is well absorbed in the body.
