Can Boiling Eggshells Really Improve Health? Here’s What Science Says
Natural remedies are trending, and one idea that keeps popping up online is boiling eggshells to prevent or treat diseases. But how much truth is behind this claim? Let’s break it down and see what research and nutrition experts really say.
What Happens When You Boil Eggshells
Eggshells are made mostly of calcium carbonate (around 95%), along with small amounts of protein and trace minerals like magnesium and phosphorus. Boiling them does a few important things:
- Kills harmful bacteria, including Salmonella, making the shells safe to handle.
- Leaches some calcium into the water, which is why “eggshell tea” or eggshell water is sometimes used as a natural calcium source.
Boiling makes eggshells cleaner and more usable, but it doesn’t turn them into a medicine.
Can Boiled Eggshells Cure or Prevent Disease?
Simply put: no, not directly.
Boiled eggshells don’t contain compounds that fight viruses, bacteria, or other diseases. However, they can indirectly support health if used thoughtfully.
Here’s How Boiled Eggshells Can Help
1. A Natural Calcium Boost
Calcium is essential for strong bones, teeth, nerve function, and muscle activity. A deficiency can lead to brittle bones, nail problems, and cramps.
By boiling, drying, and grinding eggshells into a fine powder, you can make a natural calcium supplement. This may help prevent calcium-related deficiencies—but it’s not a cure for disease.
Important: Always sterilize eggshells and grind them finely to avoid contamination or digestive issues. Consult your doctor before adding homemade supplements to your routine.
2. Reduce Waste and Live Sustainably
Using eggshells instead of discarding them supports eco-friendly living. While this doesn’t directly cure disease, living sustainably can improve your environment and overall well-being.
3. Healthier Plants for Better Nutrition
Boiled eggshell water can act as a natural fertilizer. Calcium strengthens plant cell walls, helping crops resist pests, rot, and fungal infections. Healthier plants produce more nutritious food, indirectly boosting human health.
So while eggshell water won’t cure illness, it can contribute to a healthier diet and support your immune system naturally.
Common Myths About Boiled Eggshells
Some internet claims are simply not true:
- “Drinking eggshell water cures arthritis or diabetes.”
- “Boiled eggshells detox the body.”
- “Eggshells can replace medicine.”
Eggshells are rich in minerals, but they are not substitutes for medical treatment or a balanced diet.
Safe Ways to Use Boiled Eggshells
For Calcium Supplements:
- Rinse eggshells thoroughly.
- Boil for 10 minutes to sterilize.
- Dry completely (in sunlight or oven).
- Grind into a fine powder using a blender.
- Store in a clean jar and add small amounts (½ teaspoon per day) to smoothies or soups.
For Plants:
- Boil crushed eggshells in water for 10–15 minutes.
- Let the water cool, strain, and use it to water your plants.
This supplies calcium and helps balance soil acidity, encouraging stronger, healthier plants.
