Calcium is very abundant throughout the Earth''s crust and can be mined anywhere. Calcium can be obtained from many minerals but is most commonly taken out of limestone, marble, dolomite, gypsum, anhydrite or aragonite. Discovered in 1808 by Sir Humphry Davy of England, calcium derives its name from the Latin word meaning lime.
You can encourage your kids to get enough calcium in their diet by choosing calcium-rich foods such as milk, cheese, and yogurt.Children should eat three age-appropriate servings of dairy products per day and adolescents should eat four servings per day or the equivalent.
