Choose a free-from snack bar by matching the current pack’s ingredients and any ‘may contain’ statement to the particular allergens you avoid. A gluten-free, dairy-free or vegan claim does not settle other allergy questions: for example, Nakd Cocoa Delight contains cashews, while Tesco’s listing also warns that it may contain soya, peanuts and other nuts.
The useful starting point is the allergen you need to avoid, not a brand’s general free-from positioning.
Check the ingredients and any precautionary statement for that allergen on each flavour and pack size. The Food Standards Agency explains that ‘may contain’ labelling communicates a possible unintended presence of an allergen; it is different from an ingredient deliberately used in the recipe.
If you avoid gluten or dairy as well as peanuts, tree nuts or soya, assess each requirement separately. A bar can carry one free-from claim while naming another allergen in its ingredients or precautionary statement.
Check the exact pack that will be eaten, particularly when changing flavour or buying a multipack. Information for one bar in a brand’s range should not be assumed to apply to another.
Start with the allergen you must avoid, then check what each claim covers and whether the pack matches the product you intended to buy.
| Priority | What to check | Your needs |
|---|---|---|
| Named allergens | Read the full ingredients list for the allergen you avoid. Read any ‘may contain’ statement separately: the Food Standards Agency describes this as information about possible unintended presence, not a recipe ingredient. | I need to know whether my allergen is listed as an ingredient or named in a precautionary warning before choosing the bar. |
| Scope of a free-from claim | Check precisely what a gluten-free, dairy-free or vegan claim describes, then screen for other allergens. Nakd lists cashews in Cocoa Delight; Tesco also lists a precautionary warning for soya, peanuts and other nuts. | A gluten-free or dairy-free claim helps with one requirement, but I still need to check any other allergens I avoid. |
| Exact pack | Match the flavour and pack size to the label in your hand. Check the ingredients and precautionary wording on that pack before it is eaten, rather than relying on another flavour or an online listing. | When I buy a different flavour or multipack, I want the allergen information for that specific product. |
These descriptions do not answer every allergy question. Tesco’s listing for the gluten-free TREK Original Oat Protein Flapjack names soya ingredients and warns that it may contain peanuts, nuts and milk.
Use the claim for the attribute it names, then check the ingredients and precautionary statement against every allergen you avoid.
A brand name does not identify the ingredients of a particular flavour. Nature Valley’s Chocolate & Coffee Protein bar, for example, contains peanuts, soya and milk and may contain tree nuts, according to Nature Valley UK.
Read the label for the exact flavour and pack size, including when switching from a single bar to a multipack.
A listing can help narrow down options, but the bar being eaten needs its own ingredient and precautionary-label check.
Compare the physical pack with your allergen requirements before eating it. If the product identity or allergen wording is unclear, do not rely on the online description to resolve it.
These examples show why suitability belongs to a specific product and label, rather than to a brand as a whole.
Graze makes flapjacks and other snacks using ingredients that include wholegrains, fruit and nuts, according to the brand.
The range includes protein snack bars with product-specific allergen information.
Alpen’s own allergy information says its products contain wheat, barley or oats.
Its Dark Chocolate & Peanut Protein Bar is a nut-led example.
Nakd’s Cocoa Delight is a fruit-and-nut bar; the brand lists dates, cashews, raisins and cocoa powder as ingredients.
TREK offers protein flapjacks, including an Original Oat product listed by Tesco.
These bars offer different flavours and pack formats to check against your own allergen requirements. None can be selected on its name or a general free-from claim alone: use the current pack’s ingredients and precautionary statement to make the final choice.

If you avoid peanuts, check this peanut-named variant’s full ingredient list before considering it. The pack contains four 40g bars; also read its precautionary statement for any other allergens you avoid.

The nut-named flavour calls for an ingredient check if you avoid peanuts or tree nuts. This is a pack of four 40g bars; check its own allergen and ‘may contain’ wording rather than using another Nature Valley flavour as a guide.

Check this Biscoff-flavour flapjack’s ingredients and precautionary statement against the allergens you avoid. The pack contains three 50g flapjacks; information for a different TREK flapjack does not establish this variant’s suitability.

The listing uses both Peanut Delight and Cocoa Hazelnut names. Confirm the flavour and full allergen statement on the physical pack before choosing it, particularly if you avoid peanuts or tree nuts. The title specifies four 35g bars.

If you are considering an oat flapjack, check this Cocoa Oat variant’s ingredients and precautionary statement for each allergen you avoid. Its title specifies sixteen 50g flapjacks; the allergen information for TREK Original Oat should not be assumed to cover it.
GOV.UK’s August 2026 consumer advice says UK food businesses must inform consumers when they use any of the 14 regulated allergens as ingredients. For a packaged snack bar, read the exact pack’s ingredients and allergen information for the substances you avoid; also check any precautionary statement.
No. A gluten-free claim does not establish the absence of other allergens. Nakd lists cashews in Cocoa Delight, and Tesco’s listing warns that it may contain soya, peanuts and other nuts. Check the current pack against your particular allergens.
It is precautionary wording about an allergen that could be unintentionally present, rather than one deliberately listed as a recipe ingredient, as the Food Standards Agency explains. Read the named allergen in that warning alongside the ingredients when assessing the bar.
Use a website to narrow down products, but check the physical pack before eating. Match its flavour and pack size, then read its current ingredients and precautionary statement rather than relying on information for a similar bar.
