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%).
