Do Calcium-Containing Antacids Interfere With Calcium Absorption?

No. Although stomach acid is necessary for some forms of calcium to be absorbed into the body, antacids do not interfere with this process. Calcium supplements taken with meals provide enough stomach acid for optimal absorption. Although calcium carbonate acts as an antacid, it can both neutralize the stomach acid and still be used by the body. Calcium carbonate supplements act as antacids and calcium carbonate antacids can serve as a source of calcium. The available calcium is the same.
