Although calcium antacids may alter the absorption of
, the clinical importance of this effect appears to be minimal.
Calcium-containing antacids, when taken with zinc supplements, might substantially decrease zinc absorption.
However, the presence of a meal appears to mitigate this effect. Finally, calcium antacids might also impair the absorption of
