• Almost 99 percent of calcium is deposited in your bones and teeth. The rest is distributed through the blood stream and utilized by the cells.
• Most of your calcium requirements can be supplied by milk and other dairy products. But if you are lactose intolerant, your best alternatives would be green vegetables, rooibos tea, sea foods, and nuts.

Lets talk about some History!

It was first discovered in about the 1st century, but was not isolated until 1808, when Sir Humphry Davy really experimented with calcium and stated it as an element.

Calcium's origin name was from a Latin word 'calcis', meaning lime.
