Compare elemental iron per daily serving, not the weight of its compound. UK dietary needs are 8.7 mg for adult men and women aged 50+, and 14.8 mg for women aged 19–49. NHS advice says 17 mg/day or less from supplements is unlikely to cause harm; this is not a target or a total-intake upper limit. Iron is not routinely needed by everyone. Read the dose guide ↓
