calcium is usually found under rocks and in bones and muscles

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.
