Showing Biotin in the nutrient table
Give the amount of Biotin per daily dose, in µg, and the %NRV. A daily dose of 150 µg works out as 150 ÷ 50 × 100 = 300% NRV. Check other doses with our %NRV calculator.
The nutrient table names the nutrient. The ingredients list names the form used, such as D-biotin.
Is there a maximum dose?
The UK has no legal maximum for biotin in food supplements. The Department of Health and Social Care advice, published on the NHS website, is: 0.9 mg (900 µg) 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 (7.5 µg).
- “Biotin contributes to normal energy-yielding metabolism”
- “Biotin contributes to normal functioning of the nervous system”
- “Biotin contributes to normal macronutrient metabolism”
- “Biotin contributes to normal psychological function”
- “Biotin contributes to the maintenance of normal hair”
- “Biotin contributes to the maintenance of normal skin”

Labelling notes
Hair, skin and nail products often use high doses of biotin. High biotin intake can interfere with some blood tests, and many brands add a note about this.
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.
