This is one of those viral claims that sounds strange, but eggshells really can be repurposed safely. They’re rich in calcium and trace minerals, so instead of tossing them, you can use them in a few practical ways. Here’s what works and what’s safe:
🥚 How to safely use eggshells
1. Clean and boil first
- Rinse eggshells thoroughly
- Boil for 5–10 minutes to kill bacteria (like salmonella)
- Let them dry completely
2. Grind into powder
- Crush with a mortar, pestle, or blender
- Powder can be very fine for easier use
✅ 5 practical uses for eggshells
🪴 1. Natural fertilizer
- Rich in calcium for plants
- Sprinkle in soil or mix into compost
🦷 2. Calcium supplement (for humans)
- Mix small amounts of finely ground eggshell powder into food
- 1 teaspoon ≈ 2,000 mg calcium carbonate
⚠️ Do not consume raw or large amounts—always boil and grind. Consult a doctor if taking calcium supplements.
🐞 3. Pest deterrent in the garden
- Crushed eggshells around plants deter slugs and snails
- Sharp edges are uncomfortable for pests
🍳 4. Add to compost
- Balances pH and adds minerals
- Speeds up decomposition
🧽 5. Household cleaning
- Ground eggshells can act as a gentle abrasive
- Mix with a little water to scrub stubborn residue in pots
⚠️ What to avoid
- Don’t use unboiled eggshells in food
- Don’t overdo supplements—too much calcium can harm kidneys
- Avoid using eggshells as a “cure-all” for vague health claims
✔️ Bottom line
Boiling and grinding eggshells lets you recycle a natural, mineral-rich resource safely—good for plants, DIY projects, and controlled calcium supplementation.
