Health benefits

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 which also contribute to the proper functioning of the body.
