Eggshells Are A Great Supplement For Calcium

You probably follow the same breakfast preparation-routine every day: crack an egg open to whisk it for an omelet or peel a hard-boiled egg, then toss the eggshells away. But who has ever thought about the value of eggshells?

1. Calcium Supplement

Ninety-seven percent of the content of the eggshells we so callously discard is calcium carbonate, according to a 2005 study published in the Brazilian Journal of Poultry Science.

2. Toothpaste

The shiny, tough substance covering the outside of your teeth is called the enamel. It is composed of minerals and protects your teeth from weakness and decay. When you gorge on sugary and caffeinated beverages or junk foods too often, the bacteria in your mouth react with the carbohydrates and sugar to generate acid, which gradually wears off the enamel and all the essential minerals with it. A solution made of chicken eggshell powder was successful in remineralizing the enamel of people who had suffered teeth lesions.


3. Plant Fertilizer

If you are gardener, you’ve probably used agricultural lime to condition and nourish your soil. A highly beneficial additive that decreases soil acidity, agricultural lime boasts calcium carbonate as its main component. Eggshells are 97 percent calcium carbonate and contain traces of other minerals, such as phosphorous, magnesium, sodium and potassium.

4. Stains form Mug

All of us have old cups and mugs that have become stained inside from holding caffeinated drinks over a prolonged period. While many people simply choose to toss such mugs out, some of you hold onto them, maybe because you don’t see the point of discarding a mug simply because it is stained, or perhaps it has sentimental value.
