Calcium vs. Calcium Carbonate: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on November 18, 2023
Calcium is a chemical element with the symbol Ca, while calcium carbonate is a compound made up of calcium, carbon, and oxygen with the formula CaCO₃.

Key Differences
Calcium is an essential chemical element found in various foods, vital for maintaining bone health and carrying out numerous body functions. Calcium carbonate, on the other hand, is a naturally occurring compound derived from calcium, often found in rocks and used in antacids and dietary supplements.
