This article explains why boiled eggshells are sometimes recommended as a natural calcium supplement, how to prepare them safely, and what benefits they may offer.
Explain

Why Eggshells?
- Rich in calcium: Supports strong bones, teeth, and muscle function.
- Eco-friendly: Reduces waste by reusing kitchen scraps.
- Affordable: Provides a free alternative to store-bought supplements.
