How to Make Powdered Eggshells for a Natural Calcium Boost

Using powdered eggshells in smoothies or other drinks can provide a natural, sustainable way to boost your calcium intake, promoting strong bones, teeth, and overall health. However, it’s essential to properly sterilize and dry the eggshells to avoid contamination risks, and to consume it in moderation to prevent potential side effects from excessive calcium intake.

Powdered egg shells are a valuable source of calcium and can be a great way to utilize kitchen scraps for nutritional benefits. Here’s a breakdown of the health benefits, potential side effects, and safety considerations:

Health Benefits (Calcium)

Rich in Calcium: Eggshells are made primarily of calcium carbonate, which is easily absorbed by the body. Approximately 1 gram of eggshell provides around 380-400 mg of calcium, making it an excellent natural supplement.

Bone Health: Calcium is crucial for maintaining strong bones and teeth. Consuming adequate calcium helps reduce the risk of osteoporosis and bone fractures, especially as we age.

Muscle and Nerve Function: Calcium is also essential for proper muscle contraction and nerve function.

Heart Health: Calcium plays a role in regulating heart rhythm, ensuring that muscles, including the heart, function properly.

Side Effects

Excess Calcium: Overconsumption of calcium (more than 2,500 mg per day for adults) can lead to hypercalcemia, a condition where calcium builds up in the bloodstream. This can cause kidney stones, impaired kidney function, constipation, and interference with the absorption of other minerals like zinc and iron.

Recommendations: Stick to about 1/2 teaspoon of powdered eggshells per day, which provides approximately 400-500 mg of calcium, depending on the size of the shells.

Potential Digestive Issues: Some people might experience digestive discomfort such as gas or constipation when consuming high amounts of calcium supplements.

Cautions

Salmonella Risk: There’s a risk of contamination from bacteria like Salmonella if the eggshells are not cleaned or sterilized properly.

Prevention: Boiling the eggshells for 15 minutes, as mentioned in your process, should kill any bacteria, including Salmonella. Thorough washing before boiling and proper drying in the oven also reduces the risk. Make sure the shells are dry and brittle after baking before grinding them into powder.

Heavy Metals: Eggshells can contain trace amounts of heavy metals like lead, depending on environmental factors where the chickens are raised. While these amounts are generally low, it’s important to source eggs from trusted farms or organic suppliers when possible.

Proper Dosage: Overuse of eggshell powder without guidance can lead to calcium overdose. It’s wise to keep track of your total calcium intake from all sources, including diet and supplements, to avoid complications.

Powdered Eggshells for Calcium Supplement

Ingredients:

Eggshells from at least 12 eggs (can be collected over time and stored in the freezer)

Instructions:

• Collect and Wash:
  Collect a minimum of 12 eggshells. If you don’t use eggs regularly, store the shells in the freezer until you have enough.

  Thoroughly wash the eggshells to remove any remaining egg whites or yolk.

• Sterilize:
  Place the cleaned eggshells in a pot of water and bring it to a boil.

  Boil the eggshells for 15 minutes to sterilize them, reducing any risk of bacteria like Salmonella.

• Dry:
  Remove the sterilized eggshells from the pot and place them on a paper towel to remove excess moisture.
• Bake:
  Preheat your oven to 225°F (107°C).

  Place the eggshells on a baking sheet in a single layer and bake for 20 minutes, or until completely dried out and brittle.

• Grind:
  Once the shells are cooled and dry, pulverize them using a food processor, coffee grinder, or high-powered blender until they form a fine powder.

  If needed, finish by grinding any larger pieces with a mortar and pestle to achieve a consistent texture.

• Store:
  Transfer the powdered eggshells to a clean, airtight container.

  Store the container in a cool, dark place, and use within one month.

• Usage:
  Add 1/2 teaspoon of powdered eggshells to smoothies, drinks, or other foods to get approximately 400-500 mg of calcium.

Note:
Ensure proper sterilization and drying to avoid contamination risks. Keep track of your total calcium intake to prevent overconsumption.

The nutritional breakdown for 1/2 teaspoon of powdered eggshells is approximately:

Calcium: 600 mg

This makes it an excellent natural source of calcium, providing a substantial amount for daily intake. ​
