Calcium what is it in? And how much do I need?
The mineral calcium (lime) gives firmness to the skeleton
and teeth. Calcium is also needed for the proper functioning of muscles and for
guiding impulses to the nerves.
Calcium is among others involved in blood clotting, cell
growth and hormone metabolism. It also contributes to the energy of our body
cells.

What is it in?
Calcium is found mainly in dairy products like milk and
cheese. Bread, vegetables, pulses and potatoes contain less calcium than milk,
but do contribute to the overall supply of calcium.
How much do I need?
The necessary amount of calcium is dependent on age and sex.
According to the Health have adult men and women (19-50 years) on average 1,000
milligrams (= 1 gram) of calcium required. This corresponds to 4 to 5 glass
milk.
