Eggshells are a natural source of calcium carbonate, the same compound found in many commercial calcium supplements. Preparing eggshells properly allows you to create a safe, fine powder that can be used as a dietary supplement to support bone strength and overall wellness. This recipe focuses on cleanliness, safety, and simplicity, ensuring the shells are free from bacteria and ground into a usable form.
The process is straightforward but requires care. By boiling and baking the shells before grinding, you eliminate harmful microbes and make the calcium more bioavailable. The result is a fine powder that can be added to smoothies, soups, or sprinkled lightly over food. It’s a sustainable way to use something that would otherwise be discarded, transforming it into a nourishing addition to your diet.
INGREDIENTS:
- 12 clean eggshells (from boiled or raw eggs)
- Water (for boiling)
INSTRUCTION:
- Collect and clean shells: After using eggs, rinse the shells thoroughly to remove any egg white or yolk residue. Peel away the inner membrane if possible, as this can affect texture.
- Boil for safety: Place the shells in a pot of water and boil for 10 minutes. This step kills bacteria and ensures the shells are safe for consumption.
- Dry completely: Drain the shells and spread them on a baking sheet. Bake at 200°F (95°C) for 10–15 minutes, or until completely dry and brittle.
- Grind into powder: Once cooled, transfer the shells to a coffee grinder, blender, or mortar and pestle. Grind until you achieve a fine, flour-like powder.
- Store properly: Place the powder in an airtight glass jar. Keep it in a cool, dry place.
SERVINGS:
This recipe yields approximately 1 cup of calcium powder, depending on the number of shells used. One teaspoon of powder contains roughly 800–1,000 mg of calcium.
NOTE:
Eggshell calcium powder should be used mindfully. While it is a natural source of calcium, it is not a substitute for medical treatment of joint or bone conditions. Adults generally require 1,000–1,200 mg of calcium per day, but intake should be balanced with vitamin D and magnesium for proper absorption.
The powder can be added to smoothies, soups, or sprinkled lightly over meals. It has little flavor, so it blends easily into food. However, it should always be consumed in moderation, as excessive calcium intake can cause health issues.
This recipe is not just about nutrition—it’s about sustainability and resourcefulness. By repurposing eggshells, you reduce waste and create something beneficial. The process itself is rewarding, connecting you to the idea that everyday kitchen scraps can be transformed into valuable wellness tools.
Ultimately, Homemade Eggshell Calcium Powder is a simple, eco-friendly way to support bone health. It embodies the principle that small, thoughtful practices can make a meaningful difference in daily life.
