Calcium carbonate is a highly bioavailable and widely utilized calcium salt, serving as a critical dietary supplement and therapeutic agent. It is primarily indicated for the prevention and treatment of calcium deficiencies and as an effective antacid for symptomatic relief of hyperacidity. This compound offers a high elemental calcium content, making it a efficient choice for supporting skeletal integrity and managing gastric discomfort under professional guidance.
Features
- High elemental calcium content (approximately 40% by weight)
- Rapid reactivity with gastric acid for effective neutralization
- Available in multiple formulations including chewable tablets, capsules, and powder
- Generally well-tolerated with a favorable safety profile
- Often combined with Vitamin D to enhance calcium absorption
Benefits
- Supports the development and maintenance of strong bones and teeth
- Helps reduce the risk of osteoporosis and related fractures
- Provides rapid relief from heartburn, acid indigestion, and upset stomach
- Aids in the regulation of neuromuscular and cardiovascular function
- Contributes to normal blood clotting processes
- Supports overall mineral balance in the body
Common use
Calcium carbonate is commonly used for the dietary management of insufficient calcium intake, particularly in populations at risk for osteoporosis such as postmenopausal women and the elderly. Therapeutically, it is employed as an antacid to alleviate symptoms associated with gastroesophageal reflux disease (GERD), peptic ulcer disease, and general dyspepsia. It may also be used adjunctively in the management of chronic kidney disease to control hyperphosphatemia, though this requires careful medical supervision.
Dosage and direction
For calcium supplementation, the typical adult dose ranges from 500 mg to 1500 mg of elemental calcium per day, divided into two or three doses. As an antacid, doses usually range from 500 mg to 2000 mg as needed, not to exceed maximum daily recommendations. Administration with meals can enhance absorption for supplementation purposes, while antacid use is typically recommended between meals or at bedtime. Chewable tablets should be thoroughly masticated before swallowing, and tablets should be taken with a full glass of water. Always follow specific product labeling and healthcare provider recommendations.
Precautions
Patients with a history of kidney stones, hypercalcemia, or hypophosphatemia should use calcium carbonate under strict medical supervision. Those with phenylketonuria should check formulations for aspartame content. Long-term high-dose use may lead to milk-alkali syndrome, particularly when combined with dairy products. Calcium carbonate may interfere with the absorption of other minerals and medications; separate administration by at least 2 hours. Use cautiously in patients with decreased gastric acid production as absorption may be impaired.
Contraindications
Calcium carbonate is contraindicated in patients with known hypersensitivity to any component of the formulation. It is contraindicated in cases of hypercalcemia, hypercalciuria, calcium renal calculi, and hypophosphatemia. Contraindicated in patients with severe renal impairment or failure without appropriate medical supervision. Should not be used as an antacid in patients with appendicitis symptoms, acute abdominal pain, or intestinal obstruction.
Possible side effect
Common side effects may include constipation, flatulence, and bloating. Less frequently, nausea, vomiting, and gastric discomfort may occur. Excessive use may lead to hypercalcemia, manifesting as fatigue, weakness, headache, nausea, vomiting, and altered mental status. Long-term excessive use can result in alkalosis, renal impairment, or calcification of soft tissues. Hypophosphatemia may develop with prolonged high-dose administration.
Drug interaction
Calcium carbonate may decrease the absorption of tetracycline antibiotics, quinolones, bisphosphonates, levothyroxine, and iron supplements when taken concurrently—separate administration by at least 2-4 hours. May potentiate the effects of digitalis glycosides, potentially leading to cardiac arrhythmias. Thiazide diuretics may increase the risk of hypercalcemia when combined with calcium supplements. Concurrent use with aluminum-containing antacids may increase aluminum absorption, particularly in renal impairment.
Missed dose
If a dose is missed, take it as soon as remembered unless it is nearly time for the next scheduled dose. Do not double the dose to make up for a missed one. Maintain the regular dosing schedule. For antacid use, which is typically taken as needed, no specific missed dose protocol applies.
Overdose
Symptoms of overdose may include nausea, vomiting, loss of appetite, constipation, abdominal pain, dry mouth, thirst, and increased urination. Severe overdose may lead to hypercalcemia, manifesting as confusion, lethargy, coma, cardiac arrhythmias, and renal impairment. Treatment involves discontinuation of calcium intake, hydration, and in severe cases, administration of loop diuretics, glucocorticoids, or dialysis under medical supervision. Seek immediate medical attention for suspected overdose.
Storage
Store at room temperature between 15-30°C (59-86°F) in a dry place protected from light and moisture. Keep container tightly closed when not in use. Do not store in bathroom cabinets where humidity levels may fluctuate. Keep all medications out of reach of children and pets. Do not use after expiration date printed on packaging.

Reviews
“After being diagnosed with osteopenia, my physician recommended calcium carbonate supplementation. Following six months of consistent use with vitamin D, my follow-up DEXA scan showed significant improvement in bone density. The chewable tablets are convenient and well-tolerated.” - Margaret T., 68
“As a gastroenterologist, I frequently recommend calcium carbonate as a first-line antacid for appropriate patients. Its rapid onset of action and favorable safety profile make it an excellent choice for managing occasional heartburn and acid reflux symptoms.” - Dr. Evan R., MD
“I’ve been using calcium carbonate for years to manage my occasional indigestion. It provides reliable relief within minutes without the chalky aftertaste of some other antacids. I appreciate that it serves dual purpose for both calcium supplementation and acid control.” - James K., 52
