• Calcium and acid rebound: a reappraisal PubMed

    Calcium, as carbonate or other salts, causes an increase in gastric acid secretion owing, at least in part, to direct ionic stimulation. Another possible mode of action involves antral alkalinization with subsequent gastrin release. Other antacids, notably magnesium hydroxide and aluminum hydroxide, may therefore also cause rebound, but the data in this area are less convincing. Despite the

    Calcium citrate Wikipedia

    Unlike calcium carbonate, which is basic and neutralizes stomach acid, calcium citrate has no effect on stomach acid. Calcium carbonate is harder to digest than calcium citrate, and calcium carbonate carries a risk of "acid rebound" (the stomach overcompensates by producing more acid), so individuals who are sensitive to antacids or who have difficulty producing adequate stomach acid may choose calcium

    Science questions: Acid + Carbonate = what reaction?
