I googled top 10 sources of calcium and NONE listed egg shell powder as a source. 😕 I personally eat soft boiled eggs everyday and always consume the fallen, cracked, bits and pieces of egg shell together with the yolk and white.
Here are 9 reasons why the egg shell is such an underrated source of calcium.
- Egg Shell’s Calcium Content Is Huge
- 93% of eggshell is calcium.
- 1 egg is about 57g.
- 1 egg’s shell is 6g. (11% of egg’s weight)
- Recommended Daily Intake for calcium for adults is 1g.
Which simply means that just 1 egg’s shell meets much more than your 1 day’s RDI! 😮
Egg shells are potentially better than food grade purified calcium carbonate. However, calcium from the shells of organic eggs (88%) are much more bioavailable compared to non-organic ones (48%).
Actually, there are 27 beneficial elements found in egg shells such as:
- Strontium. An element used by toothpaste manufacturers to effectively relieve pain in sensitive teeth.
- Fluorine. Found as fluoride in toothpaste and drinking water, it helps prevent tooth decay by making the tooth more resistant to acid attacks from plaque bacteria and sugars in the mouth.
- Methionine. An essential amino acid used to prevent liver damage in acetaminophen (Tylenol) poisoning.
- Cysteine. Used along with nitroglycerin as an efficient drug that opens up blood vessels and improves blood flow.
- Lysine. Reduces cold sores.
- Isoleucine. A branched chain amino acid which induces muscle protein synthesis, the rebuilding of muscle tissue that occurs as a result of the stresses that we place on our body.
Other important minerals include magnesium, phosphorus, silicon, sodium, potassium, iron, sulfur, aluminum, etc.
Egg shell powder reduced pain from osteoarthritis, increased mobility, and stopped loss of bone density in post-menopausal women who participated in the study by J. Rovensky of the National Institute of Rheumatic Diseases.👊💥
The best way to store egg shells is in sun/oven dried, powdered form in an airtight container in the fridge. A coffee grinder will get you finer powder but a pestle and mortar is easier to use. Do note that the egg shells should be boiled (212F/100C) or at least brought to 140F/60C to kill off salmonella and other bacterial contamination.
An egg, with enough calcium to last you 2 days or more, costs way less than $1.
Once egg shells are in powdered form, you can add them into smoothies, sprinkle onto salad, spread over a pizza, scatter over sandwiches, or even add a pinch into a glass of water.
Wait, what? Yeap. You see, coffee is naturally acidic, some more than others. The more acidic it is, the more bitter. Egg shells, on the other hand, is alkaline. Adding powdered egg shell reduces coffee’s bitterness by neutralizing some of the acidity.
Eggshells will provide your pet turtle with a natural source of calcium and help your chicken/bird produce eggs with thicker shells.
