Ingredients
- Eggshells from clean eggs
- Water
Equipment
- Saucepan
- Baking tray
- Coffee grinder or spice grinder
- Fine mesh strainer
- Airtight glass jar
Step 1: Wash the Eggshells
Rinse the shells thoroughly to remove any remaining egg white or yolk.
Step 2: Boil the Eggshells
Place the shells in boiling water for 10 minutes.
This helps reduce the risk of bacteria such as Salmonella.
Step 3: Bake the Shells
Spread the shells on a baking tray.
Bake at 200°F (95°C) for 10–15 minutes until completely dry.
Step 4: Grind into Powder
Use a clean coffee grinder or spice grinder to grind the shells into a very fine powder.
The finer the powder, the easier it is to mix into foods.
Step 5: Store Properly
Transfer the powder to an airtight glass container.
Store it in a cool, dry place.
How to Use Eggshell Powder
A small pinch can be mixed into:
- Smoothies
- Yogurt
- Oatmeal
- Soups
- Homemade bread
- Pancake batter
Because eggshell powder is extremely high in calcium, only a small amount is needed. Avoid excessive intake.
Recommended Calcium Intake
Daily calcium needs vary by age and sex. Most adults require approximately:
- 1,000 mg per day (ages 19–50)
- 1,200 mg per day for many women over 50 and men over 70
Total calcium intake should include food and supplements combined.
Other Ways to Support Bone Health
Strong bones depend on more than calcium alone.
Include:
- Vitamin D
- Weight-bearing exercise
- Adequate protein
- Magnesium-rich foods
- Potassium-rich fruits and vegetables
- Avoid smoking
- Limit excessive alcohol consumption
Safety Tips
- Always boil and dry eggshells before grinding.
- Grind them into an extremely fine powder to reduce the risk of sharp particles.
- Do not consume dirty or cracked eggshells.
- Avoid taking large amounts, as excessive calcium can increase the risk of kidney stones and other health problems.
- If you have kidney disease, a history of kidney stones, or disorders affecting calcium metabolism, consult your healthcare provider before using eggshell powder.
