IronVitamins and minerals
Iron is important in making red blood cells, which carry oxygen around the body.
A lack of iron can lead to iron deficiency anaemia.
Good sources of iron
Good sources of iron include:
- liver (but avoid this during pregnancy)
- meat
- beans
- nuts
- dried fruit – such as dried apricots
- wholegrains – such as brown rice
- fortified breakfast cereals
- soy bean flour
- most dark-green leafy vegetables – such as watercress and curly kale
How much iron do I need?
The amount of iron you need is:
- 8.7mg a day for men over 18
- 14.8mg a day for women aged 19 to 50
- 8.7mg a day for women over 50
You should be able to get all the iron you need from your daily diet.
Women who lose a lot of blood during their monthly period (heavy periods) are at higher risk of iron deficiency anaemia and may need to take iron supplements.
Speak to your GP or a registered dietitian for more advice.
What happens if I take too much iron?
Side effects of taking high doses (over 20mg) of iron include:
- constipation
- feeling sick
- vomiting
- stomach pain
Very high doses of iron can be fatal, particularly if taken by children, so always keep iron supplements out of the reach of children.
What does the Department of Health and Social Care advise?
Most people should be able to get all the iron they need by eating a varied and balanced diet. If you take iron supplements, don't take too much as this could be harmful.
Taking 17mg or less a day of iron supplements is unlikely to cause any harm. But continue taking a higher dose if advised to by your GP.
