Eggshells Can Pump Your Calcium Levels

Many factors contribute for the human body to lose calcium. At the top of the list are sitting too much and an excessive consumption of carbonated beverages, alcohol and even coffee.  Pregnant and women in menopause, elderly and people with digestive issues, are especially prone to calcium deficiency.

90 percent of the eggshell content is made of calcium. Plus, it’s easy for the human body to absorb it, because the chemical content of eggshells is almost identical to the human teeth and bones. Thus, we can safely say that eggshells are the best and most effective natural source of this mineral.

Ingested in right doses, eggshells do not only help treat calcium deficiency, but also help prevent and treat osteoporosis; lower high blood pressure and cholesterol levels; and stimulate the bone marrow, improving the production of blood cells.

In addition, eggshells contain copper, iron, zinc, manganese, fluorine, chromium, phosphorus  and molybdenum.

Many health experts and nutritionists recommend the consumption of ground eggshells, as a highly effective, all-natural calcium supplement. Daily intake levels go from 0.05 to 0.10 oz of ground eggshells, depending on the age; or ¾ to 1 teaspoon, divided in three daily doses, dissolved in water. Consult your doctor, or a nutritionist, for your recommended daily intake.

How To Make Eggshell Powder

For the preparation of this powder, you’ll need the following:

  • Coffee grinder
  • 1 box of eggs (12)
  • A glass jar


First, remove the yolk and white of the eggs. You can use them to make a tasty omelet, or some delicious pastry or bagels. Place the empty eggshells in the carton box, until you reach up to 12. Then, wash them well under running water, to remove any dirt and egg white remains. Next, fill a pot with water and carefully put the eggshells inside it. Bring the water to a boil, in order to eliminate any pathogens.

Cook the eggshells for about 10 minutes, and then take them out and drain them. Once you’ve done this, put them aside on a baking sheet, and leave them overnight, so that they can dry off completely. In the morning, put the eggshells in the coffee grinder, and grind them, until you get a fine powder. Put the powder in a glass jar and store it in a cool place, away from moisture.

Tip: Don’t exceed your recommendable daily dose, as it may hurt your digestive track.
