where does calcium come from
Answers.comÂ® is making the world better one answer at a time. Calcium comes from stars, I think from white dwarf stars that go supernova. Hopefully someone can improve this by giving more specifics.
Quick Answer. All calcium in the universe was originally created inside stars. When these stars exploded, many elements, including calcium, were launched outward into space. Some eventually reached the surface of the Earth billions of years later.
Calcium is found naturally in dairy products such as milk, yogurt and cheese. Calcium citrate is often referred to as a sour salt, as it has both sour and salty tastes. It is manufactured in a fermenting process: calcium hydroxide is used to neutralize citric acid. The resulting product -- calcium citrate - is then filtered and cleaned.
