Nutrition

There is more calcium in the body than any other mineral, and it has several important functions.

These include:

• helping to build strong bones and teeth
• regulating muscle contractions, including heartbeat 
• ensuring that blood clots normally

A lack of calcium could lead to a condition called rickets in children or osteoporosis in later life.

Good sources of calcium

Good sources of calcium include:

• milk, cheese and other dairy foods
• green leafy vegetables – such as broccoli, cabbage and okra, but not spinach
• soya beans
• tofu
• soya drinks with added calcium
• nuts
• bread and anything made with fortified flour
• fish where you eat the bones – such as sardines and pilchards

How much calcium do I need?

Adults need 700mg of calcium a day.

You should be able to get all the calcium you need from your daily diet.

What happens if I take too much calcium?

Taking high doses of calcium (over 1,500mg a day) could lead to stomach pain and diarrhoea.

What does the Department of Health advise?

You should be able to get all the calcium you need by eating a varied and balanced diet.

If you take calcium supplements, don't take too much. Taking 1,500mg or less a day is unlikely to cause any harm.
