Showing Manganese in the nutrient table
Give the amount of Manganese per daily dose, in mg, and the %NRV. A daily dose of 2 mg works out as 2 ÷ 2 × 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 manganese sulphate.
Is there a maximum dose?
The UK has no legal maximum for manganese in food supplements. The Department of Health and Social Care advice, published on the NHS website, is: 4 mg or less a day from supplements is unlikely to cause harm for most people; 0.5 mg or less for older people.
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 (0.3 mg).
- “Manganese contributes to normal energy-yielding metabolism”
- “Manganese contributes to the maintenance of normal bones”
- “Manganese contributes to the normal formation of connective tissue”
- “Manganese contributes to the protection of cells from oxidative stress”

Labelling notes
The lower figure for older people matters for products marketed at over-50s.
