Today I started using eggshell powder as a calcium supplement but something makes no sense, everywhere I read says that half of egg will yield 400-500mg of calcium and egal 1/2 teaspoon, well I used 12 eggshell and it yield me around 80gram and of course I tried to weight half of a teaspoon and I come up with 1.5g. Logically it makes no sense for half a teaspoon to egal 400mg since half a teaspoon of refined sugar is 2g, so I doubt calcium weight 5 times less then white sugar. What should I do? 400mg of calcium is about 1/7 of a teaspoon for me, why the hell do I get that measurement? Any clue? I can't find proper information anywhere.
