Health Benefits
Eggshells contain about 90% calcium carbonate, an essential mineral for strong bones and teeth. After proper cleaning and grinding, they can actually be consumed in small amounts as a natural supplement. To prepare them, simply boil the shells for about 5 minutes, dry them in the sun or in the oven, and then grind them into a fine powder.
This powder can be added to juices, smoothies, or soups to give your body an extra boost of calcium. Some studies suggest that calcium from eggshells is just as well absorbed as that from commercial supplements, making it a natural way to prevent osteoporosis and strengthen bones.
In addition to calcium, eggshells also contain trace amounts of magnesium, phosphorus, and zinc — all minerals that support overall health and proper body function.
