Before we get into the “how-to,” I just want to say thank you for being the kind of person who looks for ways to reuse, repurpose, and make the most out of what you have. In a world that encourages waste, finding value in something as simple as an eggshell is both powerful and inspiring.

Most of us crack open an egg, toss the shell, and never think twice. But what if I told you those fragile shells are actually tiny powerhouses—packed with calcium and minerals your body craves, and nutrients your plants will thrive on? With a little prep, you can turn kitchen scraps into natural remedies and garden gold. Let’s dive in!

Why Eggshells Are More Than “Waste”
Eggshells are made up of about 90% calcium carbonate—the very same form of calcium you’ll find in many store-bought supplements. On top of that, they contain trace minerals like magnesium, phosphorus, and zinc, which all play important roles in keeping your body (and your garden soil!) healthy.
By repurposing eggshells, you’re not only cutting down on waste, but also gaining a zero-cost nutrient source for both yourself and your plants.
Eggshells for Your Health 🥚💪
Believe it or not, eggshell powder can be a natural calcium supplement. When properly prepared, it’s safe to consume and may help support:
- Bone health & density (helpful in preventing osteoporosis)
- Strong teeth
- Muscle and nerve function
- Immune health
How to Make Eggshell Powder for Health
- Collect & Rinse – Save your eggshells and rinse them to remove egg residue.
- Boil – Place shells in boiling water for about 5 minutes to eliminate bacteria.
- Dry – Spread shells out to dry in the sun, or bake in a low oven (200°F/95°C) for 10 minutes.
- Grind – Use a coffee grinder, blender, or mortar and pestle to grind shells into a fine powder.
👉 Add a teaspoon of eggshell powder to smoothies, soups, or juices for a natural calcium boost.
✨ Pro tip: A squeeze of lemon juice helps your body absorb the calcium even better!
Eggshells for Your Garden 🌱🌼
Plants love eggshells as much as we do. Adding crushed shells to your soil provides calcium and other trace minerals, helping your garden thrive.
Here are a few ways to use them outdoors:
- Soil Amendment – Mix crushed shells into your garden soil or compost to boost nutrients.
- Seed Starters – Fill half an eggshell with soil and plant a seed inside—once it sprouts, plant the whole thing in the ground.
- Pest Control – Crushed shells sprinkled around plants can help deter slugs and snails.
- Tomato & Pepper Support – Calcium from eggshells helps prevent blossom-end rot.
Eggshells for Everyday Home Hacks
- Natural Cleaner – Mix ground eggshells with soapy water to scrub pots and pans.
- Drain Cleaner – Drop crushed shells into your sink strainer to trap debris and prevent clogs.
- Face Mask Boost – Blend powdered shells into an egg white mask for extra minerals.
Storage Tips
- Store dried, ground eggshell powder in an airtight jar for up to 3 months.
- Keep garden-use shells in a separate container until ready to crush and spread.
- For food use, always boil shells before grinding to ensure safety.
