Calcium Carbonate Tablets and Supplements – Uses, Side Effects, and More

What is calcium carbonate?

Calcium carbonate is a naturally occurring calcium salt commonly used as a food additive, antacid, phosphate binder, or dietary supplement.

As a medicine, it can help:

  • Treat certain digestive problems (gastroesophageal reflux, acid reflux)
  • Treat conditions associated with low calcium levels (osteoporosis, hypothyroidism)
  • As a Phosphate Binder in Patients with Chronic Kidney Disease

Calcium carbonate supplements are available as tablets, chewable lozenges, oral suspensions, or powders. Your body gets the most calcium from powdered calcium carbonate, but other forms are also effective.

What are the uses of calcium carbonate?

This medication is used to treat symptoms caused by too much stomach acid, such as heartburn, stomach upset, or indigestion. It is an antacid that reduces stomach acid levels.

Calcium carbonate has a variety of medical uses. Although its best-known use is as an antacid, it can also be used to help control or prevent the following conditions:

  • Low calcium levels (hypocalcemia): Calcium carbonate is a common ingredient in calcium supplements. Chronically low levels of calcium in the blood may be caused by conditions such as osteoporosis, hypothyroidism, and hypoparathyroidism.
  • Gastroesophageal Reflux Disease and Heartburn: The antacid properties of calcium carbonate can relieve symptoms of digestive problems such as acid indigestion and heartburn. Calcium carbonate relieves symptoms by neutralizing the stomach acid that causes these symptoms.
  • Chronic kidney disease: Calcium carbonate acts as a phosphate binder and may help prevent bone disease in people with kidney disease.
  • Preeclampsia: Calcium supplementation can help reduce the risk of high blood pressure (preeclampsia) during pregnancy.

How much calcium carbonate should you take?

Calcium carbonate is generally considered safe as a daily calcium supplement.

But if you find yourself taking calcium carbonate regularly to relieve digestive problems, your doctor can help you investigate the root cause of your problem. Long-term use or abuse of antacids may have negative health effects.

The recommended dosage of calcium carbonate depends on your specific health needs. Experts generally recommend a daily supplement of no more than 500 milligrams (mg) of calcium carbonate because this is the amount that is best absorbed.

Doctors may recommend higher doses of calcium carbonate (up to 1,000 mg) for short-term use, but intake during this period should not exceed 8 grams per day.
