Showing Iron in the nutrient table
Give the amount of Iron per daily dose, in mg, and the %NRV. A daily dose of 14 mg works out as 14 ÷ 14 × 100 = 100% NRV. Check other doses with our %NRV calculator.
The nutrient table names the nutrient. The ingredients list names the form used, such as ferrous fumarate.
Is there a maximum dose?
The UK has no legal maximum for iron in food supplements. The Department of Health and Social Care advice, published on the NHS website, is: 17 mg or less a day from supplements is unlikely to cause harm.
Authorised health claims
These are examples of authorised claims on the GB nutrition and health claims register. Use them word for word or with wording that means exactly the same, and only when the daily dose provides at least 15% of the NRV (2.1 mg).
- “Iron contributes to normal cognitive function”
- “Iron contributes to normal energy-yielding metabolism”
- “Iron contributes to normal formation of red blood cells and haemoglobin”
- “Iron contributes to normal oxygen transport in the body”
- “Iron contributes to the normal function of the immune system”
- “Iron contributes to the reduction of tiredness and fatigue”

Labelling notes
Iron overdose is dangerous for young children, so the “keep out of reach of young children” statement matters most here. Many brands add a specific iron warning.
Check before you print. Claims and dose advice are summarised from the GB nutrition and health claims register and the NHS vitamins and minerals pages, as of October 2026. Confirm your final wording against the register.
