What Are Eggshells Made Of?
I used to wonder this after we got our own chickens and they began laying. It's a fascinating process! One time, I happened to open the back side of our nesting boxes and one of the Mamas was in the process of laying. Up she went, and I got to watch the "birth" of an egg!
Chicken egg shells are about 95% Calcium carbonate. There are many types of calcium supplements on the market, but calcium carbonate is the closest to the calcium in our own teeth and bones! Why not get your calcium from nature's best place---your own wholesome food!?
Some Quick Facts About Eggshells
An eggshell is about 95% calcium carbonate. The remaining 5% consists of other important minerals.
One eggshell provides about 700 mg to 850 mg of calcium! That's 1/2 to 1 whole daily serving of calcium for an adult.
The shell of an egg is only about 10% of the total egg, by weight.
Tiny pores cover the surface of the eggshell, allowing oxygen in and toxins and carbon dioxide out!
Chickens will sometimes eat their own eggs---ostensibly for the calcium in the eggshell.
We give our dogs each an egg a day, raw. I found out they love to eat the eggshell and all! (This is what led me begin to research eggshells and their safety for internal use.
Did you know chickens coat their eggs with a clear substance as it exits the vent? This quickly dries and creates a protective barrier against bacteria and other organisms. This is called "the bloom." That's why you don't need to refrigerate fresh eggs that haven't been washed! And...they last a SUPER long time when they are not washed.
Why Should You Bother Making Your Own Eggshell Calcium Powder?
You can go out and buy calcium supplements, sure. But, I've learned a lot about the supplement industry in the past few years. I was a dedicated weight lifter for awhile, and I also sold vitamin supplements for one of the best companies out there, in addition to being a student of herbalism for many years. I read everything I could and can get my hands on if it involves natural health.
Personally, I no longer trust most products on the store shelves. Over and over, the FDA has found that what a product label states is in the ingredients, is not what is actually in it! And those are the ones that are caught!
These are large manufacturers too, which are supposed to adhere to strict FDA compliance laws. It seems there are few consequences for the large manufacturers, since so much of what is available in the stores is either not great quality or is adulterated in some way. (Note: I tend to place the small Mom & Pop operations in a completely different category. Shop Small!)
Not to mention, the freshness of the product on store shelves is definitely in question. How long has the product been sitting on the shelves? What is the length of time from beginning of the process to the final product?
And most important, WHERE does the supplement actually come from? Is it from a petrochemical by-product or process (like many are?) Or is it from a pure, trustworthy, and natural source?
I look at the supplement bottles on the store shelves, and not only am confused by the prolific number of them, but the labels are often misleading too. That's why---If I can make it myself, I sure do. Especially if it's easy, there is just no excuse.
Frankly, I like to KNOW what is in what I put in my body. That's one of the reasons I just love to make my own supplements, herbal teas, foods, grow my own vegetables and meats, and make my own medicines.
Here is a way to turn a scrap (egg shells) into your medicine, as Hippocrates famously suggests! So, in an ...eggshell (lol), that's why I use my egg shells to make my own Calcium supplement. There are many uses for calcium powder too! It never goes to waste!
Before I go into the directions for making your own calcium powder from eggshells, here is a little information you should know about calcium, because there are differences.
1. There are two main kinds of calcium you can use as a supplement. Calcium carbonate and calcium citrate.
2. Calcium carbonate is what 95% of the eggshell is made of, and it most closely resembles our own bones and teeth. The other minerals found in eggshells help our bodies actually use and absorb the calcium. You do need to take calcium carbonate (eggshell calcium) with food, and it is the hydrochloric acid in our stomachs that helps us absorb the calcium.
3. Calcium citrate is another form of calcium that can be ingested. It does not have to be taken with food, since the acid it contains helps your body metabolize it. There are some who feel one type of calcium is better than the other, but essentially, they both do the same thing. I prefer the carbonate form because it is closest in composition to our own bones and teeth.
4. Here is a government website that explains all about calcium, including the amounts to take depending on your age, gender, and other factors.
5. Making your own calcium supplement with eggshells is super easy, practically free, and WAY better for you because you'll know where it comes from.
How to Make Your Own Calcium Carbonate from Your Eggshells
Step 1) First, rinse and save your shells.
You should plan on having the shells from at least 18 eggs.
You MUST consider the source of your eggs.
The quality of the shell of your eggshells is only as good as the food the chickens eat and the environment in which they live. If those poor chickens are in a cruel and inhumane laying torture chamber (i.e. a large egg farm where they are caged their whole life and often have their beaks cut so they don't harm each other from stress), I will not support them. I haven't bought commercial eggs in years.
I'm fortunate enough to raise my own chickens, so I know how they live and eat. Plus, I don't clean them off with chemicals and bleach, as commercial eggs are. But if you cannot do that, then PLEASE buy the best eggs you can: Pasture raised, organic, soy free.
Don't get pasture raised confused with pasteurized. Pasture raised refers to the way the chickens get to live their lives in addition to what they eat. Pasture raised eggs are more expensive. But, to me, that expense is worth it---especially if you are feeding children.
If you can't raise your own chickens, try to source your eggs from local farmers or backyard egg sellers. People who raise chickens in their backyards often sell their extra eggs to offset feed costs.
Step 2) Boil the shells.
I like to boil the shells for about 10 minutes or so to kill any pathogens. I know not everyone does this, but I feel it's important, especially if you are buying your eggs from the store. You don't know who has touched/handled the eggs or the cleanliness of the processing facility. Please don't skip this step!
Step 3) Bake the shells.
Cool them a bit, then shake off excess moisture. Lay them out on a piece of aluminum foil or a cookie sheet. BAKE at 200 to 250 degrees for about 20 minutes until they are completely dried out. I've left mine a bit longer and it hasn't hurt them. Be sure they are completely dried.
Step 4) Grind them into a fine powder.
Now place the slightly crushed shells in a spice or coffee grinder! Grind until you have a fine powder. You want it as fine as possible if you are going to take it internally.
And that's it! :-) You now have your own Calcium carbonate supplement!
Final Thoughts About Eggshell Calcium Powder
I love this stuff. It's easy to make, I'm so comfortable using it, and it's FREE. Triple WIN. There are many ways to use calcium powder, from the garden, to making coffee, to using it as a supplement, or in remineralizing toothpaste! It pays to make your own!
To use your calcium powder: Start small---about 1/4 to 1/2 teaspoon in your food or smoothies, and even less for children. Then build up as you get to know your own tolerance. Calcium can sometimes cause digestive issues (although, as stated above, calcium carbonate is also used as an antacid!)
You can also use calcium carbonate powder to make homemade toothpaste. You can find two great recipes for homemade tooth powder that help remineralize your teeth in this link!
Have you made your own calcium powder before? Or perhaps your own tooth powder? I'd love to know your thoughts, questions, concerns...so please leave a comment! :-)
