There are some wonderful studies that show eggshell calcium to be the best and most bio available calcium available. I find it very interesting to see people giving the recommended recipes for getting the calcium as crushed eggshells in lemon juice. They also say that this tastes quiet ‘pleasant’. I have tried the eggshell and lemon calcium recipe and find that not only does it not taste ‘pleasant’, it is quite disgusting. The best way I could describe the smell is the lovely aroma of the chemicals in a hair perm. I could not bring myself to taste it, but my husband sacrificed himself for the sake of the experiment. He confirmed that it was at least as disgusting as it smelled, probably more so. I tried dissolving the eggshells in Orange Juice, but found that the orange juice was not acidic enough to fully dissolve the shells.
While a healthy diet rich with calcium and vitamin D is preferable to supplements, eggshells, properly prepared, can be used as an effective calcium supplement for both people and dogs, when required.
Another benefit of cooked and crushed (powdered) eggshells is for treating heartburn and acid reflux. Just place a quarter of a teaspoon of the eggshell powder on the tongue, washed down with water. I find that, in most cases, the heartburn is gone in seconds, and if not, a little more won’t hurt.
Note: Do not throw the powder to the back of the throat or attempt to mix with water, it is very heavy and not water soluble.
Rinse well. Leave the film inside the shell.
Bake at 350℉ – 177℃ for 20 minutes.
Grind to a fine powder (coffee grinders are very good for this).
Store in an airtight container, indefinitely.
