More Details on Calcium Carbonate
Because it has been studied quite a bit, good information about calcium carbonate dosing is available. For some of the less-studied uses, the most effective (and safe) doses have not yet been established. Adequate Intakes (AIs) and Tolerable Upper Intake Levels (UL) have been established for the mineral.
When determining an appropriate dose for calcium carbonate, be sure to remember that every 1000 mg of calcium carbonate contains only 400 mg of elemental calcium.

Calcium carbonate can potentially interact with a number of different medications (see Calcium Drug Interactions).
It is possible to take too much calcium carbonate. Overdose symptoms may vary, depending on factors such as the dosage and whether it was taken all at once (a single massive overdose) or over a long period of time (a chronic overdose).
