Sponsored: What is calcium carbonate?

Calcium carbonate comes from limestone. You may know it in over-the-counter medication to relieve heartburn or for indigestion (antacid) or as a calcium supplement in tablets or in various beverages like plant-based beverages that have no naturally occurring calcium. 

As a food ingredient, calcium carbonate is used as an anti-caking (prevents lumps) ingredient for flours, baked items and frozen desserts.
