Each year, tons of eggshells are discarded as kitchen waste. But what if we told you these brittle white shells are actually tiny treasure troves of nutrition for both your body and your garden? Instead of tossing them into the trash, learn how to transform eggshells into powerful natural tools that boost wellness and nourish your plants.
🥚 What Are Eggshells Made Of?
Eggshells are composed of approximately:
- 95% calcium carbonate, a form of calcium that is bioavailable to plants and beneficial for human bones.
- Other minerals such as magnesium, phosphorus, potassium, and trace elements like zinc and selenium.
- Protein-rich membranes lining the inside, which contain collagen, glucosamine, and other compounds used in joint health.
🧠 FACT: According to a study published in Food and Function (2013), eggshell powder can be a viable natural calcium supplement, especially for those with osteoporosis or calcium deficiency.
