Iron contributes to normal energy-yielding metabolism and to the reduction of tiredness and fatigue. Because women lose iron through their monthly cycle, they generally need more of it than men — and low iron is one of the most common reasons women feel wiped out.
What does iron do?
Iron helps your body carry oxygen in the blood and supports normal energy metabolism and immune function. When iron runs low, many women notice tiredness, paleness and a general lack of get-up-and-go.
Why do women need more iron?
Monthly periods mean a regular loss of iron, so women of reproductive age have higher needs than men. Heavier periods, a plant-based diet or pregnancy can increase the demand further.
How can I get more iron?
Iron-rich foods include red meat, beans, lentils, tofu and dark leafy greens. Pairing plant sources with vitamin C — found in our Simple C — helps your body absorb the iron. A balanced multivitamin can also help top up everyday intake.
Frequently asked questions
How do I know if my iron is low?
Persistent tiredness, breathlessness or looking pale can be signs — but only a blood test can confirm it. Ask your GP if you're concerned.
Should every woman take an iron supplement?
No — too much iron isn't good either. Only supplement high-dose iron if a test or your GP suggests you need it.
