Dairy products are usually the things that hold calcium, and lack of calcium can affect your teeth and bones in a major way. Vitamin D is needed to absorb calcium. Coral calcium,calcium carbonate, chloride, citrate, carbide, hydroxide all have calcium in it. Sir Humphrey Davy 1808 He dissolved lime into a mercuric oxide mixture and then passed an electric current through it. England
