Check your antacids! Many over-the-counter antacids contain calcium carbonate as an active ingredient. Look for products listing calcium carbonate on the label among the ingredients. Tums, for example, is a readily available brand that uses calcium carbonate.
Important Note: Always read the label carefully to confirm the presence and quantity of calcium carbonate. Also, consult your doctor or pharmacist before using any medication, especially if you have pre-existing health conditions or are taking other medications.
Remember: Antacids are for occasional heartburn relief, not a long-term calcium supplement. If you need calcium supplementation, talk to your doctor about appropriate options.
