Who needs to check what?

The most useful starting point is the exclusion that matters to you, not a general claim on the front of the wrapper.

Festival-goers managing a food allergy

Keep the sealed wrapper available so you can check the exact bar’s ingredients and precautionary allergen wording against your avoidance plan. “High protein” does not tell you whether an allergen is present.

Vegan or dairy-free snack packers

Look for a claim that matches your requirement, then read the rest of the label. A vegan bar can still contain peanuts or soya; a dairy-free label does not address every other allergen.

Gluten-free festival snack planners

Choose a bar with an explicit gluten-free claim when that is your requirement, and check other ingredients separately. Quest, for example, describes its protein bars as gluten-free but says its OG bars use dairy-based proteins.

What matters when choosing a bar?

Set your non-negotiable exclusion first. Then compare the exact flavour and pack, because a dietary claim or retailer filter does not answer every ingredient question.

Priority What to check Your needs
Exact allergens Read the full ingredients and allergen declaration for the chosen flavour. Check any “may contain” wording against your avoidance plan. I need to know whether this particular bar declares an ingredient I avoid, rather than relying on the brand or range name.
Dietary claims Match vegan, dairy-free or gluten-free wording to the requirement it actually addresses. Check other relevant allergens separately. A vegan or dairy-free option could work for me, but I may also need to avoid peanuts or soya. A gluten-free claim alone does not answer those questions.
Polyols Look at the sweeteners, nutrition information, serving size and any warning about excessive consumption. If polyols affect me, I want to check the label before packing several bars for a long day.
Pack information Check the current product information when choosing a flavour, then read the physical wrapper before eating it. Keep the wrapper if you will need to refer back to it. I want the ingredients for the bar I actually packed, especially when several flavours look similar.

Common buying mistakes

  • Assuming one dietary claim covers every allergen

    Vegan, dairy-free and gluten-free describe different requirements. A vegan bar may still contain peanuts, soya or gluten-containing ingredients.

    Start with your required exclusion, then check the exact flavour’s ingredients and precautionary wording for everything else you need to avoid.

  • Choosing by protein content before reading the allergens

    Grenade lists peanuts, milk and soya in its Peanut Nutter bar, alongside warnings about other possible allergens. Its ingredient profile cannot be assumed to apply to every flavour in the range.

    Check the individual bar’s label before packing it. If its declared ingredients or warnings conflict with your avoidance plan, choose a different bar.

  • Treating “low sugar” as a tolerance claim

    Some low-sugar bars use polyols, and product warnings may refer to a laxative effect from excessive consumption. Sugar content alone does not tell you how you will tolerate a particular bar.

    Read the sweeteners and warning text. If you know polyols affect you, take that into account before making an unfamiliar bar your main packed snack.

  • Using a shop filter instead of the product label

    A Free From category can narrow a search, but it does not establish that every listed flavour meets every allergen requirement. Food from a festival trader may also have a different information format from a prepacked bar.

    Check your bar’s wrapper. When buying from a trader, ask for the food’s allergen information before ordering; the Food Standards Agency says food businesses must provide allergen information for both prepacked and non-prepacked food.

Brand ranges to consider

These ranges illustrate different places to begin a search; suitability still depends on the chosen product and flavour.

Grenade

Grenade offers protein bars in confectionery-style flavours.

  • Its range provides options for shoppers comparing conventional protein bars.
  • Grenade lists peanuts, milk and soya in Peanut Nutter and warns that it may contain other allergens. Check each flavour independently.

PhD

PhD’s Smart Bar range includes Smart Plant bars labelled suitable for vegans and vegetarians.

  • PhD states that Smart Plant provides 20g protein and less than 1g sugar per serving.
  • Vegan suitability does not establish peanut- or soya-free suitability; check the chosen flavour’s ingredients.

Myprotein

Myprotein has a separately browsable dairy-free protein-bar category.

  • The category can help narrow a search when avoiding dairy.
  • Read each bar’s label for any other ingredients or allergens you need to avoid.

Quest

Quest describes its protein-bar collection as gluten-free.

  • Its gluten-free claim gives shoppers a specific criterion to check on a chosen bar.
  • Quest says its OG bars use dairy-based proteins, so the range is not a dairy-free route.

Barebells

Barebells has Original, Soft and Vegan bar lines.

  • The distinct lines make it possible to start with a preferred bar type.
  • Barebells states that all its bars contain nuts or may contain traces of nuts. Check the exact bar for your other exclusions too.

Tesco

Tesco provides Free From browsing and gluten-free and milk-free filters across relevant snack categories.

  • Filters can help locate candidate bars by a stated dietary requirement.
  • A category or filter is not a substitute for the current product ingredients and physical pack.

KIND Protein Crunchy Peanut Butter, 3 x 42g

KIND Protein Crunchy Peanut Butter, 3 x 42g

This three-bar peanut butter pack is worth comparing if its ingredients fit your requirements. Its allergen information identifies peanuts and soya and warns that it may contain tree nuts; it contains honey, so it is not a vegan option. Check the current label for any gluten-free or dairy-free requirement rather than assuming either claim.

Frequently asked questions

Does vegan mean a protein bar is suitable for every food allergy?

No. Vegan describes the absence of animal-derived ingredients, not the absence of peanuts, soya, wheat or other allergens. Check the exact flavour’s current ingredients and precautionary wording against the allergens you avoid.

What allergen information should I ask a UK festival trader for?

Ask for the allergen information for the food you intend to buy before ordering. The Food Standards Agency says food businesses must provide allergen information for prepacked and non-prepacked food and drink. For food prepacked for direct sale in England, Wales and Northern Ireland, its guidance also requires the food’s name and a full ingredients list.

What does “gluten-free” mean on a UK food label?

The Food Standards Agency defines “gluten-free” as no more than 20 mg/kg of gluten in the food as sold to the final consumer. It is a gluten claim, not a statement that the bar is free from milk, nuts or other allergens.

Does low sugar tell me whether a bar contains polyols?

No. Check the ingredients, nutrition information and any warning on the particular bar. Some bars use polyols, and an excessive-consumption warning may matter if you are sensitive to them or plan to pack several bars.

Is a supermarket Free From filter enough to choose a bar?

No. A filter can help you find candidates for a stated exclusion, but it does not establish suitability for every allergen or flavour. Read the current product information and check the physical wrapper before eating the bar.
