People should avoid taking the antacid calcium carbonate in doses larger than half a gram, for despite its capacity to neutralize stomach acids, calcium carbonate can increase the calcium level in the blood and thus impair kidney function. Moreover, just half a gram of it can stimulate the production of gastrin, a stomach hormone that triggers acid secretion.

Summary
People should avoid taking calcium carbonate in doses larger than half a gram. Why? Because, despite its ability to neutralize stomach acids, it can increase the calcium level in the blood and therefore impair kidney function. Just half a gram of calcium carbonate could stimulate the production of gastrin, which causes acid secretion.

Strongly Supported Conclusions
Half a gram of calcium carbonate could cause both acid neutralization and acid secretion.

A
Cessation of gastrin production is a more effective method of controlling excess stomach acid than is direct neutralization of stomach acid.
We don’t know whether stopping gastrin production is a more effective way to control excess stomach acid. We only know that gastrin is a cause of acid secretion.
B
People who avoid taking more than half a gram of calcium carbonate are less likely than average to suffer from impaired kidney function.
We don’t know the average likelihood of suffering from impaired kidney function.
C
Doses of calcium carbonate smaller than half a gram can reduce stomach acid more effectively than much larger doses do.
We don’t know whether smaller does of calcium carbonate are more effective than larger doses for reducing stomach acid.
D
Half a gram of calcium carbonate can causally contribute to both the secretion and the neutralization of stomach acids.
We know that calcium carbonate has the capacity to neutralize stomach acid, but we also know that half a gram of calcium carbonate has the potential to cause acid secretion through the production of gastrin.
E
Impaired kidney function may increase the level of calcium in the blood.
We don’t know whether impaired kidney function increases the level of calcium in the blood. Rather, we know that increased levels of calcium in the blood could cause impaired kidney function.
