Showing Niacin in the nutrient table
Give the amount of Niacin per daily dose, in mg, and the %NRV. A daily dose of 16 mg works out as 16 ÷ 16 × 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 nicotinamide.
Is there a maximum dose?
The UK has no legal maximum for niacin in food supplements. The Department of Health and Social Care advice, published on the NHS website, is: 17 mg or less of nicotinic acid, or 500 mg or less of nicotinamide, 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 (2.4 mg).
- “Niacin contributes to normal energy-yielding metabolism”
- “Niacin contributes to normal functioning of the nervous system”
- “Niacin contributes to normal psychological function”
- “Niacin contributes to the maintenance of normal skin”
- “Niacin contributes to the reduction of tiredness and fatigue”
Check the full register entry before you print: some claims have extra conditions. See our health claims guide and how to check a claim on the register.
Labelling notes
The form matters: nicotinic acid can cause flushing at low doses, nicotinamide doesn’t. The upper advice differs by form, so confirm which form your formula uses.
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.
