Important considerations About 99% of calcium in the body is stored in bones and teeth and amounts to approximately 1200 grams. Modern culture dictates that we need dairy foods to fulfil most of our calcium needs. However a careful study of the whole food profiles that follow, along with calcium absorption and retention mechanisms, will reveal that many foods can contribute substantially to our calcium requirements.
Life stages that demand special cognisance regarding calcium intakes are childhood, young adulthood, and older age. A woman of childbearing age has an RDI of calcium of 1000 mg. The percentages and milligrams amounts below look similar because of the 1000mg value.
An infant’s entire calcium needs are met by under 3 cups of breast milk per day.

Using the government RDI guidelines is a good place to start.
