Question

How does the calcium extract from the coral? Is the calcium extracted when the coral is alive?

Answer 1

depends on the type, there is sea coral calcium and fossilized coral calcium.  The fossilized type is found buried on different land sites and is typically more pure than the sea coral calcium.  To obtain the sea coral calcium, they use huge vacuums and basically just suck up as much coral as they can from the ocean floor.  they then take it off to be processed in various facilities, so no the coral doesn't survive the process.
