Eggshells are a natural and sustainable source of calcium carbonate, while magnesium can be added using simple, natural ingredients. Together, they make an effective supplement to support strong bones, teeth, and overall health. Here’s how you can create your own DIY calcium-magnesium supplement at home.
Ingredients
- Eggshells: From 6–12 eggs (thoroughly cleaned)
- Lemon juice or apple cider vinegar: 1 cup (for calcium absorption)
- Epsom salt: 1 teaspoon (magnesium source)
- Water: For rinsing and sterilizing
Instructions
- Clean the Eggshells
- After using the eggs, rinse the shells thoroughly to remove any leftover egg whites or yolks.
- Remove the thin membrane inside the shell for better processing.
- Sterilize the Eggshells
- Boil the eggshells in water for 10 minutes to kill bacteria.
- Drain and let them dry completely, preferably in the sun or using a clean towel.
- Bake the Eggshells
- Preheat your oven to 200°F (90°C).
- Spread the dried shells on a baking sheet and bake for 10–15 minutes. This ensures the shells are completely dry and easy to grind.
- Grind Into a Fine Powder
- Use a high-powered blender, spice grinder, or mortar and pestle to grind the shells into a fine powder.
- Store the powder in an airtight container.
- Prepare the Calcium-Magnesium Supplement
- In a glass jar, mix 1 teaspoon of the eggshell powder with 1 cup of freshly squeezed lemon juice or apple cider vinegar.
- Add 1 teaspoon of Epsom salt (natural magnesium sulfate) and stir well.
- Let the mixture sit for 30 minutes to allow the calcium from the eggshells to react with the acid, creating a bioavailable supplement.
How to Use
- Take 1–2 teaspoons of the mixture daily. You can add it to water, tea, or smoothies for easy consumption.
- Store the supplement in the refrigerator and use it within a week.
Benefits
- Calcium: Supports bone density, dental health, and muscle function.
- Magnesium: Promotes relaxation, healthy nerve function, and energy production.
- Natural and Chemical-Free: This homemade supplement is free from additives, making it safe and gentle for regular use.
Pro Tips
- Always use organic or free-range eggs to avoid any contaminants.
- Consult your doctor before starting any supplement, especially if you have existing medical conditions or take medications.
