How much calcium do I need?
Adults aged 19 to 64 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 (more than 1,500mg a day) could lead to stomach pain and diarrhoea.
What does the Department of Health and Social Care advise?
