How to Make Your Own Calcium Powder from Eggshells and How to Use as Your Calcium Supplement!
Did you know you can make your own inexpensive calcium powder from eggshells? Read on to find out how (and why)!
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 food!
Some Facts About Eggshells
- Calcium Carbonate, which is 95% or so of an eggshell, is what most antacids are made of!
- One eggshell provides about 700 mg to 850 mg of calcium!
- 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 made me begin to research eggshells, their safety for internal use, and WOW, did I find out some great news!)
- 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. That's why you don't need to refrigerate fresh eggs that haven't been washed! And...they last a SUPER long time.
A Personal Opinion About Using Calcium from Eggshells
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 health naturally.
Personally, I no longer trust the products on the shelves for many reasons. 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 always 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 (like many are?) Or is it from a pure trustworthy and natural source?
There are other reasons, too, which I won't go into at this time. But suffice to say, I look at the supplement bottles on the store shelves, and not only am confused by the prolific amount of them, but the labels are often misleading too.
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. I get to know exactly what is going in to my livestock and vegetables, and I also know they are safe.
There are so many different kinds of calcium supplements too! Here is a way to turn to your food for your health! So, in an ...eggshell (lol), that's why I use my egg shells to make my own Calcium supplement. Plus, I have so much left over, there are many other uses too! It never goes to waste! I'll be sharing some of these in future posts!
Before I go into the directions for making your own calcium powder from eggshells, here is a little information about calcium. Just a little.
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 involved helps your body metabolize it.
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 Easy. Practically Free. Better for You.
How to Make Your Own Calcium Carbonate from Your Eggshells
- First, save your shells.
- You MUST consider the source of your eggs. The shell of your eggshells is only as good as the food the chickens eat and the environment in which they live. I'm fortunate enough to raise my own chickens, so I know how they live and eat. 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.
- Rinse them well, then set aside until you have enough shells.
- After you have enough, you need to boil the shells for about 10 minutes or so to kill the 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!
- 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.
- Now place in a spice or coffee grinder! Powder 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 supplement!
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!)
I will be writing another article very shortly about a variety of uses for Calcium carbonate powder! I'm excited to share! Shhh...One is for a dry shampoo!

I love this grinder because you can wind up the cord inside the base. It's also powerful and easy to use. This is the model I use for my herbal powders too!
NOTE: If you happen to click on the product above and purchase from Amazon, I will make a very small commission, but it will not cost you anything. I appreciate your support in keeping my blogging going! :-) Thank you!
