| starting_dose = Oral: 1000-1500 mg elemental calcium/day in divided doses for supplementation; IV gluconate 1 g (4.65 mEq) over 5-10 min for hyperkalemia or symptomatic hypocalcemia
| preparations = Carbonate 200, 400, 500, 600 mg elemental tablets and chewables; citrate 200, 250, 315 mg elemental; gluconate 1 g (94 mg elemental, 4.65 mEq) IV; chloride 1 g (270 mg elemental, 13.6 mEq) IV

| duration = Variable
| halflife = Not meaningfully described (electrolyte)
| bioavailability = Carbonate ~30-40% (best with food and acid); citrate ~24% (absorbable without acid; preferred in achlorhydria, PPI use, post-bariatric)

| legal = OTC (oral supplements) and [[USLegal:Prescription only|Rx-only]] (IV) in US
| mechanism = <vote slug="calcium-mech-claim">Oral calcium repletes the serum and skeletal calcium pool; IV calcium (gluconate or chloride) stabilizes the cardiac myocyte resting potential in hyperkalemia by raising the action-potential threshold relative to the membrane potential, restoring electrochemical gradient without affecting serum potassium itself.</vote> Calcium carbonate is also an effective antacid via direct gastric acid neutralization. Co-administration with iron and tetracyclines reduces absorption of both; separate dosing windows. Excess oral calcium may increase nephrolithiasis and cardiovascular events in some studies, fueling preference for dietary over supplement-driven repletion.
