Check the antacid aisle! Many common antacids contain calcium carbonate as their active ingredient. Look for brands listing calcium carbonate prominently on the label, often alongside the dosage information. Read the labels carefully to compare calcium content per tablet or capsule.
Supplement Section
Head to the vitamin and supplement section. You’ll find calcium carbonate supplements in various forms, including tablets, capsules, and powders. Pay attention to the serving size and the amount of elemental calcium per serving – this tells you how much calcium your body will actually absorb.
Consider the form: tablets are often easier to swallow, while powders can be mixed into drinks or food for easier consumption. Always follow the recommended dosage instructions on the product label. Before starting any new supplement, consult your doctor, especially if you have pre-existing health conditions.
