Hi there. I've been using generic fibercon aka calcium polycarbophil for close to a year now. But I never realized how much calcium it actually has in it. I'm concerned this might be bad for the kidneys. I don't have kidney problems currently, but I do know excess calcium can cause stones, and I definitely don't want that.
Does anybody have any data on long term use of fibercon? Should I switch to acacia to be on the safe side?
The calcium is tied up in the molecular structure of the calcium polycarbophil which is an indigestible soluble fiber. Since the body cannot digest it and it is not fermented in the colon it is unlikely that your body will absorb much of the calcium it contains. It has been used for the long term relief of C even in primary care facilities for a few decades with no apparent problems. If you have concerns speak with your physician.
