Stop throwing them away. Boil eggshells and say goodbye to… Show more

Eggshells are composed of about 90% calcium carbonate, a mineral that is essential for maintaining strong bones and healthy teeth. This natural source of calcium can be reused instead of being thrown away.

When properly cleaned and prepared, eggshells can be consumed in small quantities as a dietary supplement. To make them safe, the shells should be boiled for around five minutes to disinfect them.

After boiling, they need to be thoroughly dried, either in the sun or in the oven. Once completely dry, they can be ground into a very fine powder.

The powder can be added to juices, smoothies, or soups to increase daily calcium intake. Studies suggest that calcium from eggshells is absorbed by the body almost as effectively as commercial supplements.

In addition to calcium, eggshells contain small amounts of magnesium, phosphorus, and zinc. These minerals also play an important role in supporting overall health and proper body function.

Eggshells are also very useful in gardening. When crushed and mixed into the soil, they act as a natural fertilizer, enriching the soil with calcium and helping balance its pH level.

Reusing eggshells is a simple step toward a more sustainable lifestyle. Whether used for health or for plants, they offer a practical way to reduce waste and make better use of natural resources.
