5 Top Uses, Benefits & Nutrition Of Eggshells For Skin, Hair, Teeth & Garden !

Eggshell Benefits
If you are throwing out the eggshells after eating eggs each time, I would strongly suggest not to as it has wonderful uses and benefits. Eggshells are a rich source of calcium and each shell has about 2 grams and that is a lot of calcium!

Eggshell Nutrition & Calcium Content:

Eggshells contain around 900 mg of elemental calcium (calcium that can be absorbed by our body) and it is found in the form of calcium carbonate. It also contains other micro elements like boron, magnesium, manganese, copper, iron, molybdenum, sulfur, zinc, etc. Eggshell powder can be easily absorbed by our body.

Egg Shells In Garden:

When I was a student, our school had a beautiful rose garden that produced beautiful large roses. Eggshells from the hostel was regularly used as a manure and it kept the plants healthy.

When I had my own garden, I started using eggshells regularly. Eggshell powder helps regulate soil acidity along with adding nutrients to plants. We can also soak the egg shell powder in water overnight and then use the water next day to spray the plants.

We can use egg shell powder for plants like tomatoes, peppers and brinjal, it will greatly help prevent blossom end rot. I also like to add egg shell powder to potted plants.

What To Do With Egg Shells?

I always used to think eggshells can only be used as a fertilizer but few months back I read a research paper that proved beyond doubt that eggshell powder can be internally consumed to increase our bone density. Regular use greatly prevents osteoporosis and you can read the study that proves it here.

Eggshell powder can be used for skin, teeth and hair care too. Since it is rich in calcium, using it in the form of face pack, gives a nice glow to our skin. Applying the powder as a hair pack makes our hair glossy and shiny. Using it as a tooth paste removes plaque and tartar from our teeth naturally!

How To Make Eggshell Calcium?

To make eggshell calcium, first take 10 to 12 eggshells. When making eggshell powder, try using only organic, farm raised country eggshells for best results.

If you have boiled the eggs, then we do not need to boil the eggshells again. But if you are using the eggshells after making omelettes then I would suggest washing and boiling for 10 minutes to get rid of any bacteria.

This step is especially necessary if you are using regular eggs. Then sundry till crisp and powder immediately in a dry mixer to a fine powder and store in an airtight box.

Eggshell Powder Dosage:

1/2 tsp of the eggshell powder contains around 400 mg of calcium. Consume the eggshell powder depending on your body’s needs.

Consuming Egg Shell Powder Side Effects:

Don’t overdose on eggshell powder as overdose of calcium is also bad for us. One of the main concerns of eating eggshell powder is bacteria present in the eggshells. Boiling and sun drying will eliminate the risk of bacterial infection completely but try your best to use organic farm raised eggs for best results.

    Hi Ramya, So nice to chance upon your blog! My daughter's name is Ramya and it is good to know it is Rampriya as many North Indians call her Ramayya (after that Ramayya Osaavayya Hindi song!! Now I can explain better!:).I live in the USA and during my first pregnancy, having no family here, or much of Indian resources available here at that time, I reached out to the library and came upon a book by Adele Davis, the nutritionist. She recommended a shake every morning that contained all the nutrients and egg shell was one of the items! Just wished to share:). Thank you for an awesome site!
