Most people toss eggshells in the trash without realizing they’re a powerful, natural resource packed with calcium and other minerals. Once you discover the incredible ways to reuse eggshells, you’ll think twice before discarding them. From boosting your garden to enhancing your health, here are some brilliant uses for eggshells that will make you want to save every single one!


1. Natural Fertilizer for Plants

Eggshells are rich in calcium carbonate, a vital nutrient for plant growth. Crushing eggshells into a powder and mixing them into the soil can enhance the health of your garden.

  • How to Use: Dry the eggshells and crush them into a fine powder. Sprinkle the powder around the base of your plants, or mix it into your compost. This adds essential minerals to the soil and helps prevent blossom-end rot in plants like tomatoes.

2. Pest Repellent in the Garden

The sharp edges of crushed eggshells act as a natural barrier against pests like slugs, snails, and cutworms, which can harm your plants.

  • How to Use: Scatter crushed eggshells around the base of plants in your garden. The rough texture deters soft-bodied pests without harming your garden.

3. Calcium Supplement for Health

Eggshells are one of the best natural sources of calcium, which supports bone health, heart function, and muscle activity. You can safely consume eggshell powder as a natural calcium supplement.

  • How to Use: Boil the eggshells to sterilize them, dry them completely, and grind them into a fine powder using a blender or coffee grinder. Add about ½ teaspoon of eggshell powder to smoothies, juices, or food for an extra boost of calcium.

4. Improve Skin Health with Eggshell Masks

Eggshells are great for your skin, thanks to their minerals and collagen content. You can make a simple eggshell face mask to exfoliate and rejuvenate your skin.

  • How to Use: Grind dried eggshells into a fine powder and mix with an egg white to create a paste. Apply this paste to your face, let it dry, and then gently scrub it off. The mask helps remove dead skin cells and tightens your skin.

5. Household Cleaner

Eggshells are mildly abrasive, making them perfect for scrubbing stubborn stains and grime without scratching surfaces.

  • How to Use: Mix crushed eggshells with soapy water and use the mixture to scrub pots, pans, and stubborn surfaces like sinks and countertops.

6. Add to Coffee for Less Bitterness

This is an old trick: Adding a small amount of crushed eggshell to your coffee grounds can reduce the bitterness and acidity of coffee, giving you a smoother brew.

  • How to Use: Clean and crush the eggshells, then add them to your coffee grounds before brewing. This neutralizes some of the acidity and makes the coffee taste milder.

7. Feed Eggshells to Birds

Birds need calcium to produce strong eggshells of their own. Offering them crushed eggshells can give them a natural calcium boost.

  • How to Use: Bake the eggshells at a low temperature to kill any bacteria, then crush them into small pieces. Scatter the crushed eggshells outside to provide a healthy snack for your local bird population.

8. Treat Skin Irritations and Itchy Spots

Eggshells soaked in apple cider vinegar create a soothing mixture that can help treat minor skin irritations and itchy spots.

  • How to Use: Soak crushed eggshells in apple cider vinegar for a couple of days. Use the solution as a natural remedy for skin irritations or rashes, applying it with a cotton ball.

9. Strengthen Your Nails

If you want stronger, healthier nails, eggshells can help. Adding finely ground eggshell powder to your nail care routine can make a difference.

  • How to Use: Mix ground eggshells with your favorite nail polish or cuticle oil and apply it to your nails regularly to help strengthen them.
