The Surprising Nutritional Power of Eggshells
Eggshells are made up of about 90% calcium carbonate , the same compound found in many over-the-counter calcium supplements . In fact, just one eggshell contains nearly 800 mg of calcium , which is close to the daily recommended intake for adults .
In addition to calcium, eggshells also contain:
- Magnesium – Essential for muscle and nerve function

- Potassium – Helps regulate fluid balance and heart health
- Sodium – In trace amounts, supports hydration
- Amino acids – The building blocks of protein
