When it comes to eggs, most of us crack them open, use the insides, and toss the shells without a second thought. But what if we told you that those seemingly useless eggshells are actually packed with health benefits and practical uses? It’s time to rethink your kitchen waste—because eggshells are about to become your new wellness secret.

The Surprising Nutritional Power of Eggshells

Eggshells are made up of 95% calcium carbonate, a form of calcium that’s incredibly easy for the human body to absorb. Just one gram of eggshell powder can provide up to 1,000–1,500 mg of calcium, which meets or even exceeds the daily recommended intake for most adults.

Calcium is essential for:

Strong bones and teeth
Muscle function
Nerve transmission
Heart health

With osteoporosis becoming a growing concern, especially among aging populations, finding natural calcium sources like eggshells is more important than ever.
