The resulting powder can be added to juices, smoothies, or soups to provide the body with extra calcium. Some studies show that the calcium in eggshells is as well absorbed as that in 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. When crushed and mixed with soil, they enrich it with calcium and help balance the pH. This is especially useful for crops like tomatoes, peppers, and eggplants that need 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.
