Eggshell Calcium: Benefits, Uses, Side Effects & How to Use It Safely

Eggshell calcium is a natural calcium source made from finely ground chicken eggshells. Because eggshells consist primarily of calcium carbonate, they have become a popular natural alternative to traditional calcium supplements. Eggshell calcium is commonly used to support bone health, teeth strength, healthy aging, and overall mineral wellness.

In addition to calcium, eggshells contain trace amounts of other minerals that contribute to their nutritional value. Today, eggshell calcium is available in powders, capsules, and dietary supplements.
