Misty,
OMG! I have called my gastro about this after reading several books on how lack of stomach acid stops calcium digestion. He said no way was there a connection. I have been on prevacid twice a day for years (and H2 blockers before PPIs were invented) and like you, taking Actonel just made me double up again on the prevacid, and then lead to horrendous muscle pain that didn't stop (see my thread in osteoporosis). No wonder I'm getting osteoporosis.
What's the answer if you must have acid controls? My nurse sister-in-law suggested taking prevacid/nexim in the a.m. and calcium at night, when the drugs may have begun to wear off.
Taking Tums just blocks stomach acid anyway and defeats the purpose, but it might allow a little more calcium in.
I have read repeatedly, however, that calcium citrate does not require stomach acid to be digested and is an answer to this problem.
Any thoughts?
