Answer:

Teeth, bones, kidney stones...

Explanation:

Calcium is a trace element found in much organic matter. In its solid form, it is found in parts of the body that need to be rock-hard: bones and teeth.

It is also found in kidney stones, in hard form (from condensed powdered calcium). These can be quite painful, so drink plenty of water to avoid their formation!
