Calcium from eggshell presents healthy, balanced calcium due to trace amounts of other minerals contained in it. Eggshell calcium is probably the best natural source of calcium, and it is easier for your body to digest and absorb.
Researchers from Nederland have reported recently a highly positive effect of eggshell calcium (with added magnesium and vitamin D) on bone mineral density in a scientific study (double blind, placebo-controlled). Laboratory test and measures of bone density were carefully made in these studies. The eggshell supplemented group had measurable increases in bone density in their hip bones, after one year.
The ultimate bone-building combination of eggshell calcium and vitamin D3 was also well documented in Japanese studies. Researchers at the Japan Women’s University, Yokyo studied a combination of vitamin D3 and eggshell powder in animals with osteoporosis. Not only was the eggshell powder with vitamin D3 able to improve bone mineral density, but it did it without significantly increasing blood calcium levels.
You can use any kind of egg (chicken, goose, duck), but it is best to use organic or certified organic eggs from free-range birds. If the bird does not get proper nutrients the eggshells won’t contain the nutrients we need.
One whole medium sized eggshell makes about one teaspoon of powder, which yields about 750 – 800 mgs of elemental calcium plus other microelements, i.e. magnesium, boron, copper, iron, manganese, molybdenum, sulphur, silicon, zinc, etc. There are 27 elements in total. The composition of an eggshell is very similar to that of our bones and teeth.
Note: Elemental amounts are the amounts absorbable.
Most people require a minimum of 400 mgs per day of calcium, in addition to calcium from other food sources, so you would take 1/2 teaspoon of the powder per day. Also take 400 mgs of magnesium citrate at the same time. Calcium and magnesium need to be taken in at least equal amounts, and some people require more magnesium than calcium depending upon how much they obtain from their diet.
If you are getting muscle cramps take extra magnesium (about 150 mgs). If that doesn’t alleviate the cramps within an hour take another 150 mgs, and so on. If you get unusual joint pain and you do not have arthritis, take an additional 150 mgs of calcium. Do not take more than 500 mgs of calcium at one time because your body cannot handle it. If you need more than 400 mgs per day split up the doses during the day.
It is best to take calcium and magnesium with foods to help absorb them. Don’t forget that vitamin D is very important for absorbing minerals! In addition, all of the trace minerals, sodium and chloride are important for mineral absorption and to keep minerals balanced take the electrolyte drink.
Making Powdered Eggshells
- Wash empty eggshells in warm water until all of the egg white is removed, but do not remove the membrane because it contains important nutrients for the joints which helps arthritis.
- Lay broken pieces out on paper towels and allow them to air dry thoroughly.
- Break the eggshells up into small pieces, and grind them to into a fine powder in a food processor, blender, coffee grinder, or put them in a plastic bag and use a rolling pin to grind them. Please note that some blenders will not grind the eggshell into a fine enough powder. A coffee grinder works the best.
- Store powdered eggshells in a covered glass jar or container. Keep it in a dry place, like the kitchen cupboard.
