Is Calcium vegan?

Calcium is a reactive alkaline earth metal (symbol Ca, atomic number 20) and the fifth most abundant element in Earth's crust. In cosmetics and food supplements, calcium compounds (such as calcium carbonate, calcium phosphate) may be sourced from limestone (mineral), marine organisms (e.g. shells, coral), or produced synthetically. The vegan status depends on the specific calcium compound and its source.
