The Amazing Uses for Egg Shells

Egg ShellsPost by Contributing Writer, Katie

Egg shells are one of those things usually end up in the the garbage. Well I’m here today to tell you to NEVER toss them away again! They are like gold! I am always trying to find ways to waste less and reuse what I already have. Egg shells fit right into that category.

Egg shells are full of calcium! Each medium sized egg shell has about 750-800 mgs of calcium plus magnesium, iron, manganese, sulphur, phosphorus,silicon, gelatin, collagen and zinc. That’s only a few of them; egg shells contain 27 microelements that are able to be absorbed by your body.

They are possibly the best form of calcium and easy for your body to digest and absorb. Egg shells have been used in treatment of arthritis and joint pain. The composition of an egg shell is similar to that of bones and teeth.

It is always best to use eggs from chickens that have been pastured if possible. Second best are ones that have been feed organic soy-free feed. I use eggs from my own chickens that are fed veggie scraps, grass, bugs and organic soy/corn-free feed.

Here Are Some Ways to Use Egg Shells

Powdered Calcium Supplement

  • Carefully wash your egg shells in warm water to remove the egg white. Don’t remove the the membrane, it contains important nutrients for your joints.
  • If you want to can soak the egg shells in boiling water for 5 minutes to remove pathogens. (I don’t)
  • Let them dry.
  • Once they are dry put the egg shells in a blender or coffee grinder to make a powder, a coffee grinder works best.
  • Store in a glass jar.
  • Add ½ a teaspoon a day to your favorite beverage, apple sauce, etc.
  • If desired you can pour a little apple cider vinegar or lemon juice over the crumbled egg shells to break them down and makes them softer and forms calcium citrate.

Liquid Calcium Supplement

Mix 4 tsp of your powdered calcium supplement with 2 cups of hot water and 1 tsp of fresh lemon juice or apple cider vinegar. Cover and let cool. Strain the liquid into a glass jar and keep in the fridge. Take a teaspoon or two a day.

When using egg shells as a supplement it is beneficial to take it with fermented cod liver oil which is high in vitamin D as it helps absorb the minerals. Calcium is good for you but don’t take more than the advised amount, your body can only handle 500 mgs of calcium at a time. It is also better to take your calcium with food.

Water Kefir Boost

When brewing your water kefir, add a clean egg shell for an added mineral boost.

Less Bitter Coffee

Adding an egg shell to the filter when you make coffee makes a less bitter drink. Added bonus: both are compostable!

Broth

Add egg shells to your bone broth for an added health benefit.

Next month I will be sharing more ideas on how to use egg shells.

  • Fascinating! Maybe I’ll have to try using egg shells more often. I usually just toss them. I’ve heard they are great for sharpening the blades of your garbage disposal.

    @Mary @ Homeamde Dutch Apple Pie, Interesting, I’d never heard of egg shells sharpening the blades of garbage disposals.

  • I sometimes put them in my broth, but I never know if the nutrients are getting into the broth or not. Do you know if that is helpful or not?

    @Sarah, When I make my bone/egg broths I add a little apple cider vinegar (or any vinegar) to the pot and let it set for about an hour before I turn on the heat. This helps pull the nutrients out of the bones and egg shells. Some times I get busy and add the vinegar when I turn on the heat, this works too just not as well.

  • I’ll have to add egg shells next time I make broth. One thing I read somewhere online was to grind up the egg shells in a coffee grinder and use them as a face powder — translucent, absorbs oil and all natural! I’ve done this and it works great…just remove the membrane first :-)

    @Beth @ Turn 2 the Simple, Great tip! I’d heard of that but was afraid that I couldn’t get the powder fine enough. I’m going to try that some time! :)

  • Interesting post! I’ve been using a toothpaste from Shaklee for years that is made up of ground egg shells, does not have flouride and uses xylitol for sweetener (fights bacteria). Your teeth feel like they just came from the dentist!!

    You mentioned that our bodies can’t utilize more than 500 mg of calcium at a time. Does that mean in one day?? or in one a meal??

    So a serving would be approximately 3/4 of a teaspoon of the powder?

    [Reply]

  • Thanks for pointing that out. Our bodies can’t utillize more than 500 mg of calcium at a time. How much calcium suppliment you need depends on how much calcium you are getting from other sources. There are times when I take up to 1000 mg of calcium a day when I know I haven’t gotten any from the other foods I have eaten. A serving of the powder would be any where from 1/2- 3/4 tsp.

  • Do you put the whole shell in for bone broth or the powder?

    When washing the egg out and using to grind into a powdered supplement, i’m assuming it’s a raw shell (not from a hard boiled one).

    I grind them up and put them in my garden where I plant tomatoes. Tomatoes are a good source of calcium, and they require it in the soil.

    Get tip! I’ll be sure to do that when I plant my tomato seedlings.

    Blessings,

  • I recently used eggshells in my garden to stop the slugs from eating my seedlings. I wasn’t sure abot it, but it worked! (Here’s a link to my post about it: http://www.greenideareviews.com/2012/04/29/using-eggshells-as-a-slug-and-snail-barrier-review-does-it-work/).
    Can’t wait to see what ELSE can be done!

    @Victoria @ Green Idea Reviews, That’s great I’m glad it worked for you!

  • This is great! I’m going to share the link on our FB page!

  • Thank you so much for sharing this tip. I save all of my eggshells to put around my tomato plants. My mother did it, my grandmother did it, so I do it. However, I don’t drink a lot of milk and my husband is concerned I am not getting enough calcium. I don’t like to take supplements because who knows what is in them??? This, I think I could handle. I will be trying this out. Thanks again.

    I have used this recipe with little lemon juice to treat itchy rash I get from allergic reactions/sensitivities to some chemicals or foods. I don’t know why or how, but it has brought good relief without using steroid creams!!!! Worth a try since it is virtually free!

  • Katie, you didn’t specify how many eggshells so I put a dozen into my broth and cooked 4 hrs in my pressure cooker. The bones which were previously cooked in a soup (1.5 hrs in pressure cooker) are falling apart but the eggshells are only slightly more fragile so I wonder if it wouldn’t be better to use powdered eggshells. I do add the powdered ones to chilies and such but can definitely feel the grittiness which I don’t like, so I’m afraid of trying them in my broth – Bone broth is too precious to waste.

    Lena, what is the recipe you use?

  • […] 1) Add any vegetables about 8 hours before the broth is done. If left longer it causes the broth to become bitter and the vegetables begin to leach vitamins and minerals from the broth.  (stupideasypaleo)                                            2) Use apple cider vinegar to draw the minerals from the bones.            3) Roast beef or veal bones prior to cooking for best taste.                                          (traditional-foods)                                                                                            4) Add bones to cold water as heating them slowly helps leach minerals                                                                                                              5) Simmer beef for 48 hours and chicken for 24   (wellnessmama)                                      6) You can use your bones more than once as chronicled here!  (thenourishinggourmet)                                                                                  7) Great list of veggies NOT to add as the make it bitter, here                     8) You can add egg shells directly to the broth and they should dissolve, imparting their nutrients especially calcium to your broth.  (therealfoodguide) (frugalgranola) […]
