Showing Fluoride in the nutrient table
Give the amount of Fluoride per daily dose, in mg, and the %NRV. A daily dose of 1 mg works out as 1 ÷ 3.5 × 100 = 29% NRV. Check other doses with our %NRV calculator.
The nutrient table names the nutrient. The ingredients list names the form used, such as sodium fluoride.
Is there a maximum dose?
The UK has no legal maximum for fluoride in food supplements, and the NHS doesn’t publish a specific upper amount for it.
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 (0.53 mg).

Labelling notes
Fluoride is rarely added to UK supplements, because most people get it from water and toothpaste.
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.
