Did you know that most calcium supplements on the market today are basically limestone? Yes, that’s chalk. Conceal it within a capsule, a slickly glazed tablet, or in the form of a silky smooth liquid, and it is magically transformed into a “calcium supplement”: easy to swallow, “good for the bones” and a very profitable commodity for both the dietary supplement and mining industries. After all, a sizable portion of the Earth’s crust is composed of the stuff.
Calcium carbonate comes very cheap. But does it work?
