An eggshell is more than just a useful container for the nutritious yolk and egg white inside, an eggshell contains 95% calcium carbonate – which is very useful to strengthen our bones and protect our tooth enamel.

You may not have heard it yet, but just as you can eat the peels of organic bananas or lemons, the entire egg can also be eaten.

The shells are also an amazing source of calcium, just half an eggshell provides you with your daily recommended calcium intake. Eggshells are also known to relieve joint pain and inflammation.

Eat your eggshells

The best way to eat your eggshells? Powder them finely and add to juices, smoothies, soups, and stews.

Don’t go overboard though, if you are already getting enough calcium in your diet, you may want to find another use for them. Half an eggshell a day covers your basic calcium needs, more than that is unnecessary.

What kind of eggshells to use?

For the sake of eating a healthy, natural diet, you’ll want to make sure that the eggshells you are about to consume come from organic or free-range chickens. Eggs from factory farms are far less nutritious and may carry hidden pathogens that you will want to avoid.

If you don’t have your own hens, purchase from a local farmer or the farmers market for the healthiest farm fresh eggs possible.

And yes, you can do this with duck eggs or turkey eggs, even quail eggs too.

How to make an edible eggshell powder

To make your own calcium supplement from eggshells is super easy:

  • Set your cracked eggshells aside until you have a sufficient amount for processing at once. Rinsing them thoroughly at this stage is enough.
  • When you are ready, bring a pot of water to boil on the stove and add your shells. Sterilize them for a few minutes in the boiling water.
  • Strain and remove the eggshells, then spread them out on a baking sheet.
  • Allow them to air dry for a few hours, or overnight.
  • Bake the eggshells at a low temperature (250-300 F) for about 10 minutes, until they are nice and rattly.
  • When cool, grind the eggshells in a coffee or spice grinder. A food processor or mortar and pestle works fine too.
  • Store in an airtight glass jar, in your pantry or cupboard.

If your eggshell powder still feels too gritty, blend it further or use it in baked goods and energy bars where it can blend in, unnoticed.

You can also add some powder to your apple cider vinegar and drink one tablespoon of eggshell-infused vinegar every day as part of your healthy wake-up routine.

9 Other Brilliant Uses For Eggshells

1. Use eggshells to start seedlings indoors

In the pursuit of a plastic-free life and garden, finding a sustainable solution for starting seeds isn’t always easy.

In the past, people reused what they had, yogurt containers or the like, but at some point, plastic pots break down and need to be thrown away/recycled.

Of course, there are peat pots, newspaper pots, gourd shells, and wooden flats as examples to eco-friendly planting options, though eggshells come out as the garden winner.

Fill the shell halfway with soil, carefully place your seeds and wait for them to grow. To keep the eggshells in place, place them back in the eggshell carton.

When the plants are large enough, you can transplant the entire pot to the garden, where the shell will break down, providing added calcium to the soil around it.

2. Garden mulch

After a hearty breakfast or the baking of a delicious cake, crush your eggshells and carry them straight out into the garden!

As they slowly decompose, they will not only help to aerate the soil as they improve water flow, the eggshells will also release calcium over time. The finer you crush them, the faster they will break down.

3. Boil eggshells in your coffee

This is wonderful for two reasons. Firstly, if you are making campfire coffee over high heat, crushed eggshells will help keep the grounds from boiling over. This isn’t a common problem unless you are roughing it, but now you know how to avoid a ruined coffee if the situation ever arises.

Secondly, eggshells added to coffee make for a less acidic cup. When you experience the overwhelming bitterness from a cup of cheap coffee, or from a pot that was brewed too long, eggshells are here to save the day.

The powdered, or finely broken up shell, of just one egg is enough to make 4 cups of fantastic coffee.

Try it. It is a great way to get some calcium with your brew if you are sipping dairy-free.

4. Toss eggshells in your bone broth or stockpot

Whether you are stirring up an enormous pot of bone broth or hearty vegetable stock, adding eggshells is extremely beneficial.

It is not just calcium that you will be receiving, eggshells also contain small amounts of other minerals:

  • magnesium
  • fluoride
  • selenium
  • zinc
  • iron
  • phosphorus

It won’t change the flavor, though you will feel the nutritional boost!

5. Add them to your apple cider vinegar

Add some dried eggshells to a jar of apple cider vinegar, with the mother, and let nature science do its work. The end result will be a tincture that relieves acid reflux, treats minor skin irritations and itchy skin.

6. Homemade eggshell toothpaste

Once you make the decision to stop using standard minty fluoride toothpaste with a myriad of unpronounceable ingredients, there is no looking back.

You’ll then find all sorts of options to keep your teeth happy and clean – from activated charcoal to clay and zeolite, all the way to baking soda with coconut oil and essential oils.

Remember from up above that eggshells are similar to our own teeth? This gives us a great reason to make a very fine eggshell powder toothpaste to brush our pearly whites, holding cavities at bay.

7. Make an eggshell face mask

To nourish and tighten your skin: crush your dried eggshells in a mortar and pestle to make a fine powder. Then whisk an egg white till it is somewhat stiff and add the eggshell powder.

Spread it over your face and allow it to dry. Wash the mask off with cold water and enjoy your free facial treatment.

8. Whiten your laundry

If your whites are not so bright as they used to be and chlorine is a no-go in your natural laundry routine, why not try the method of putting eggshells into a tightly woven bag (or old stocking) with a few slices of lemon?

It doesn’t cost much, if anything, and is definitely worth a try.

9. Scrub your tough-to-clean pots

In a pinch, you can crush a few eggshells into a dirty pot, along with soap and hot water to get it clean. The shells will break up and remove the dirt as they are wonderfully abrasive.

You can use crushed eggshells in hard-to-clean vases as well for a more glistening glass surface.
