Eggshell powder is a great source of calcium for your dog. Learn how to make it in your kitchen. It's a better and cheaper calcium supplement than tablet.

Eggshell powder is a great source of calcium for your dog. And this article shows you how to make it yourself from the shell of your eggs you’ve been throwing in the bin as waste.

Is there a kitchen where eggs and eggshell is not found? I have about 50% assurance that you use egg in one way or the other in making your meal. You break the egg, empty it content into a pan and throw away the shell. Don’t you know that eggshell is as useful ingredient as its content?

What is Eggshell Powder Used for?

Eggshell is about 95% of calcium carbonate in the making. Eggshell Calcium carbonate is an essential mineral for bone, enzyme and muscle health. Study shows that eggshell calcium:

  1. Helps in the prevention and treatment of osteoporosis (low density, porous bone disease).
  2. Contains other minerals like magnesium, sodium, potassium and phosphorus which are essential to your dogs’ health.

How Do You Make Eggshell Calcium Powder?

Can you get eggshells without eggs? Obviously you certainly need eggs.

I advise you get eggs fresh from farm if possible. And get the egg of chickens not fed with soy. Shells of egg of chickens fed with soy-free feed is more calcium-rich than the egg produced by chickens fed with soy. Not only that even the content of the egg is richer for you.

Shell of egg of soy-free fed chickens are thicker and denser than that of the soy fed chickens!
The denser the eggshell, the more the calcium content.

These eggs may cost you a bit of dollar more but it is much cheaper than buying calcium tablets.

Kitchen Equipment You Need

  1. A stock pot.
  2. An effective coffee grinder.
  3. A container to store the eggshells  powder.

How do you sterilize Eggshell?

Have you empty your eggs into a pan to make your meal? Make sure the shells are well drained and put the shells back into the carton till you get about a score – 20 of them.

  1. Rinse out the eggshells in water.
  2. Boil about 7 cups of filtered water in a pot.
  3. Put the eggshells in the boiling water for 10 minutes to destroy harmful bacterial and pathogens that might have been living since you have been gathering the shells.
  4. Drain the eggshells and leave it on a cookie sheet for 4 hours.
  5. Then place the eggshells in your oven.
  6. Set the oven temperature to 200°F (about 95°C) and heat the eggshell for 10 minutes. This will completely dry the eggshell.

The Making! So Simple!

Now, once the eggshell is totally dry, ground them into powder with an effective coffee/nut grinder.

Then store your eggshell calcium powder in Mason jar – an air-tight container.
