Where is calcium found?
- Courtney (age 13)
In nature, calcium is found in rocks, chalk, and seashells. It is
found in the bones, muscles, and nerves of animals and in many
different plants. In the food you eat, there is a lot of calcium in
milk and other dairy products. There is also a good deal of calcium in
green leafy vegetables like spinach. Some foods like orange juice are
frequently supplemented with calcium too.

Follow-Up #2: Calcium and bones
where is calcium found in the bone?
- mimi (age 12)
Calcium is the main constituent of bones mainly in the chemical form of Calcium phosphate. So essentially calcium is found everywhere in normal bones. Here is a web site of interest for more detailed information: http://www.medicinalfoodnews.com/vol02/issue2/bones
