Eggshells are beneficial for us, consisting of 95% calcium carbonate, making them very similar to our own bones and teeth. It comes as no surprise then, that eggshells help to strengthen our bones and protect our tooth enamel. If we only used the shells, rather than throwing them out!

Here are some uses for eggshells: use eggshells to start seedlings indoors, garden mulch, nuourish your tomatoes with a boost of calcium, add powdered eggshells to your foods, kick the pests out, make a natural abrasive cleaner, use eggshells to deter slugs and snails, make a calcium-rich supplement for your pets, use eggshells to make homemade sidewalk chalk, use eggshells to make a natural dye for Easter eggs.
