Don't throw away eggshells anymore!

Eggshells contain approximately 90% calcium carbonate, a mineral essential for strong bones and teeth. After proper disinfection and grinding, they can be consumed in small quantities as a natural 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 a calcium supplement. Some studies show that the calcium from eggshells is absorbed as well as that from dietary 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 the proper functioning of the body.
To help the garden

Eggshells are also widely used in gardening. One of their most common uses is as a natural fertilizer. Crushed and mixed into the soil, they enrich it with calcium and help balance the pH. This is particularly beneficial for crops like tomatoes, peppers, and eggplants, which require extra calcium.

Larger pieces of shell can be placed around plants to form a natural barrier against snails and slugs. Their sharp edges keep these pests away without the need for pesticides.
