How To Make Calcium Powder From Eggshells

It’s easier than you think to learn how to make calcium powder from eggshells! Stop throwing your organic eggshells away and start using them to make homemade, organic calcium supplement powder for your calcium needs. With very little effort, from the shells you already bought with your organic eggs, you can make this easy recipe.


What you’ll need to do:


1.  COLLECT SHELLS  (organic eggs a must) – Any time you use an egg, save the empty shell in the fridge, until you’ve collected a dozen or so (or whenever you feel like making this recipe, the number of shells is not important).




2.  STERILIZE SHELLS – When you’ve collected your desired amount of shells, you want to rid them of any bacteria by boiling them in a pot of water. Use enough water to completely cover them, then bring to a boil and cook for 10 minutes.




3.  DRY SHELLS IN THE OVEN – Set oven temp at 250º. Strain off any cooked egg white bits that may have bubbled up in the water when you drain off the water from the shells. (Don’t worry if some stringy pieces of the inner membrane are stuck inside the shells, they will harden in the oven and grind down just fine). Spread the shells out on a cookie sheet. Place in a pre-heated oven and bake for 10 minutes, or until completely dry.




4.  GRIND UP THE SHELLS – You can use a blender, food processor, Vitamix, coffee grinder or a mortar and pestle. For the finest consistency, if you’re not using a coffee grinder, further grind the shells (that have been pulverized by the blender or food processor), even finer, by hand, with a mortar and pestle. Keep in a sealed jar near the stove so you remember to sprinkle the calcium powder into whatever you feel like. I have added it to, sauces, rice, stir-fry, smoothies, soups, broths, and salads. You’ve already paid for organic eggs, so you might as well take advantage of the free bonus calcium you could garner from these shells instead of having to “shell out” (ha!) more money for supplements.




Organic eggshells provide healthy, balanced calcium powder with trace amounts of other minerals contained within it: boron, iron, sulfur, zinc, copper, manganese, magnesium, 27 elements in all.  Eggshell calcium powder is ideal for increasing bone mineral density and alleviating osteoporosis.  The makeup of eggshell is very close to that found in our own bones and teeth.  A teaspoon of the eggshell calcium powder contains approximately 750 mg of absorbable calcium, best assimilated when taken with food.

So now that we know how to make calcium powder from eggshells, let’s get cracking!
