UK nutrition and health claims: a buying check
A familiar nutrient claim is useful buying evidence only when the exact wording and conditions fit the product being sold in the relevant market.
Check claim wording, conditions and product context
A familiar nutrient claim is useful buying evidence only when the exact wording and conditions fit the product being sold in the relevant market.
Capture the exact claim
01Do this: Copy the complete wording from the pack or advertisement, including the named nutrient and any qualifiers.
Why it matters: Paraphrasing can remove a condition or turn cautious authorised wording into a broader promise.
Evidence check: Keep the exact product, variant, market and date with the claim text.
Search the applicable register
02Do this: Look for the nutrient, substance and exact or materially equivalent authorised wording in the GB register where applicable.
Why it matters: A nutrient appearing in the register does not authorise every statement about it.
Evidence check: Use the official register link rather than a retailer, influencer or copied claims list.
Read every condition of use
03Do this: Check required quantities, food-category limits, mandatory accompanying wording and any population conditions.
Why it matters: A claim can fail its conditions even when the sentence resembles authorised wording.
Evidence check: Compare the conditions with the exact labelled amount and stated portion on the current pack.
Review the full sales presentation
04Do this: Check headlines, product name, testimonials and imagery for broader disease or efficacy implications.
Why it matters: The surrounding presentation can overstate an otherwise bounded sentence.
Evidence check: Use the Claim Decoder as a pattern screen, then defer unresolved classification to the official route.
Three checks before checkout
Enough detail to make the choice better informed and clearer, without turning a quick buying decision into a compliance manual.
- 1 Check whether the exact wording and its conditions appear in the applicable official register before letting the claim influence the purchase.
- 2 Match the exact flavour, variant, pack and formula rather than a similar marketplace image.
- 3 Use the current physical label for ingredients, allergens, warnings and stated serving information.

Why these checks matter in the UK
Compare the food label, ingredients, amount per stated serving, warnings and allergens; do not use the page as medical advice.
Food supplements are regulated as foods rather than medicines.
Great Britain · current
Treat a claim as a constrained label statement, not proof that the product will deliver the outcome for a particular person.
Nutrition and health claims used in Great Britain need an authorised basis and must meet the exact conditions of use.

Check the market named on the label and use the matching official source rather than assuming one UK-wide claims register.
