Nutrition Claim Checker
See which claims such as low fat, high protein or source of fibre your product can make
Enter the amounts from the nutrition table, per 100g (or per 100ml for a drink). Leave blank anything you do not have.
Reduced and light claims
These compare your product with a similar one, so they need two values.
Based on the nutrition claim conditions in the Annex to Regulation (EC) No 1924/2006, retained in UK law. This tool checks the numbers only and is a guide, not legal advice or a guarantee of compliance.
A free nutrition claim checker for UK food and drink. Enter the values from your nutrition table, per 100g or per 100ml, and see which claims your product meets, such as low fat, high protein, source of fibre or low salt, with the exact reason for each yes or no. A second panel checks “reduced” and “light” claims against a similar product. No sign-up, and nothing you enter is saved.
How to Use the Nutrition Claim Checker
- Choose food or drink. Foods are judged per 100g and drinks per 100ml, and some limits are lower for drinks.
- Enter the values from your nutrition table. Leave blank anything you do not have. A claim that needs a missing value is shown as “needs data” instead of being guessed.
- Add trans fat if the product contains any, because the saturated fat claims count saturates and trans fat together.
- Read the list. Green means you can make the claim, red means you cannot, and each line says why.
- For “reduced” or “light”, use the second panel and compare with a similar product.
What a Nutrition Claim Is
A nutrition claim is any statement that says or suggests a food has a useful nutritional property, such as “low fat”, “high in protein” or “source of fibre”. Only the claims listed in the Annex to Regulation (EC) No 1924/2006 are allowed, and each one has a condition the food has to meet. Great Britain kept this Annex in its own law after leaving the EU.
The conditions are about the food as sold. The checker applies them to the values you type in, exactly as entered, with no rounding.
The Thresholds for Each Claim
These are the numbers behind the list the checker gives you. Foods are per 100g and drinks per 100ml.
- Low energy: 40kcal or less for foods, 20kcal or less for drinks
- Energy-free (drinks): 4kcal or less
- Low fat: 3g or less for foods, 1.5g or less for drinks
- Fat-free: 0.5g or less
- Low saturated fat: saturates plus trans fat of 1.5g or less for foods or 0.75g or less for drinks, and no more than 10% of the energy
- Saturated fat-free: saturates plus trans fat of 0.1g or less
- Low sugars: 5g or less for foods, 2.5g or less for drinks
- Sugars-free: 0.5g or less
- Low sodium or salt: 0.12g sodium (0.3g salt) or less
- Very low sodium or salt: 0.04g sodium (0.1g salt) or less
- Sodium-free or salt-free: 0.005g sodium or less
Fibre and Protein Claims
- Source of fibre: at least 3g per 100g, or at least 1.5g per 100kcal
- High fibre: at least 6g per 100g, or at least 3g per 100kcal
- Source of protein: at least 12% of the energy comes from protein
- High protein: at least 20% of the energy comes from protein
Fibre has two routes, and meeting either one is enough, so the checker tries both. Protein is judged as a share of the energy, not by grams. Each gram of protein counts as 4kcal, so the sum is protein in grams times 4, divided by the kcal, as a percentage.
Reduced and Light Claims
A “reduced” claim compares your product with a similar one. The nutrient has to be at least 30% lower, or at least 25% lower for sodium and salt. You must say what you are comparing with and by how much, for example “30% less fat than our standard recipe”.
“Reduced sugars” also needs the energy to be equal to or lower than the similar product. “Reduced saturated fat” also needs trans fat to be equal to or lower. “Light” or “lite” has the same conditions as “reduced” and must also state what makes the food light.
Salt and Sodium
The limits for these claims are written in sodium. Salt is sodium multiplied by 2.5, so 0.12g sodium is 0.3g salt. Enter salt or sodium in the checker and it works out the other for you.
What This Tool Does Not Check
It checks the numbers only. A claim still has to be true and not misleading, the product needs a nutrition declaration, and some wordings are not allowed at all, such as “90% fat free”. “With no added sugars” depends on the ingredients, not on the nutrition table, so it is not in the list. The checker also does not cover vitamin and mineral claims, omega-3 claims, or special cases such as the slightly higher low-fat limit for semi-skimmed milk.

Can I say “low fat” if my food has 3g of fat per 100g?
Yes. A food can carry a low fat claim at 3g of fat or less per 100g. For a drink the limit is 1.5g or less per 100ml.
What is the difference between “source of” and “high in”?
High needs more than source. For fibre it is 6g per 100g instead of 3g, and for protein it is 20% of the energy instead of 12%.
Can I say “90% fat free”?
No. Claims of that kind are not allowed. Only “fat-free”, at 0.5g of fat or less per 100g or 100ml, is permitted.
Does “light” have its own rules?
It has the same conditions as “reduced”, so at least 30% less of the nutrient than a similar product, and you must say what makes the food light.
Why does the low saturated fat claim need my energy value?
Besides the 1.5g or 0.75g limit, the saturates and trans fat together must not provide more than 10% of the energy. The checker needs your kcal to work that out.
Is the tool free?
Yes, it is free with no sign-up, and nothing you enter is saved or sent anywhere.
