Health Benefits
Eggshells contain about 90% calcium carbonate, a mineral essential for strong bones and teeth. After proper disinfection and grinding, they can be consumed in small amounts as a natural dietary supplement. To do this, the shells are boiled for about 5 minutes, dried in the sun or oven, and then ground into a fine powder.
The resulting powder can be added to juices, smoothies, or soups to provide the body with additional calcium. Some studies show that the calcium in eggshells is as well absorbed as that in supplements, making it a natural way to prevent osteoporosis and strengthen bones.
In addition to calcium, the shells also contain traces of magnesium, phosphorus, and zinc, minerals that also contribute to proper body function.

To help the garden
Eggshells are also commonly used in gardening. One of their most common uses is as a natural fertilizer. Crushed and mixed with soil, they enrich it with calcium and help balance the pH. This is especially beneficial for plants like tomatoes, peppers, and eggplants, which require more calcium.
Larger pieces of shell can be placed around plants to form a natural barrier against snails and slugs. Their sharp edges repel these pests without the need for pesticides.

Another option is to add the shells to compost: they accelerate decomposition and enrich the compost with minerals.

Reusing eggshells is an easy step toward a more environmentally friendly and sustainable lifestyle. Whether you use them to strengthen your bones or fertilize your plants, you’re reusing a resource that would otherwise go to waste.
So, the next time you crack open an egg, remember: don’t throw the shell away so quickly, give it a second life!
