Most people toss eggshells without a second thought, but they’re actually packed with valuable nutrients. Rich in calcium carbonate—commonly found in supplements—eggshells can be repurposed to support both your health and the environment when used correctly.
For health, sterilized and finely ground eggshells can be added to smoothies or food for a natural calcium boost. They also contain trace minerals like magnesium, phosphorus, and zinc, which support bone strength and muscle function. Just be sure to boil and dry them before grinding.
In the garden, eggshells serve as a powerful, natural fertilizer. Crushed shells help improve soil quality, boost calcium levels, and even repel pests like slugs and snails. They’re especially helpful for plants like tomatoes and peppers that thrive in calcium-rich soil.
Reusing eggshells is a small but impactful habit that reduces waste and supports a more sustainable lifestyle. Instead of tossing them in the trash, turn your kitchen scraps into a healthy choice for you and a natural treat for your plants.
