Who needs to check what?

Shoppers with a diagnosed food allergy

Start with the ingredient and precautionary allergen statements for the allergen you avoid. Protein content and flavour become useful comparisons only after that check.

Milk-allergic shoppers considering vegan bars

Read the full declaration rather than relying on the vegan label. Barebells UK’s Vegan Fudge Brownie, for example, states that it may contain milk.

Shoppers comparing portable protein snacks

Once a bar meets your allergen requirements, check how much protein the stated bar or serving provides. The amount and protein source differ between the product examples from Barebells UK, Grenade, PhD and Myprotein UK.

What matters when choosing?

Screen the exact bar for allergens first, then compare protein amounts and serving sizes among the options that remain.

Priority What to check Your needs
Allergen declaration Read the current ingredients for your named allergen. Check any ‘may contain’ or facility statement against your individual avoidance advice, and inspect the exact flavour’s wrapper before eating. I need to know whether the bar contains my allergen or carries a relevant warning, regardless of the claim on the front of the pack.
Milk-based protein Look for milk ingredients, including whey, caseinate and milk protein. Check precautionary wording even on a vegan bar: Barebells UK’s Vegan Fudge Brownie says it may contain milk. If I avoid milk, a plant-based label alone does not settle whether this particular bar meets my requirements.
Peanuts, nuts and sesame Check the flavour, ingredients and ‘may contain’ line separately. Grenade identifies peanut-containing flavours, while its Cookie Dough bar listed by Tesco Groceries may contain nuts, peanuts and sesame. A flavour without peanuts in its name still needs a full declaration check if I avoid peanuts, tree nuts or sesame.
Protein per serving Compare the stated grams of protein per bar or serving and the serving weight, but only after allergen screening. Barebells UK states 15g per Vegan Fudge Brownie bar and 20g per Cookies & Cream bar; Myprotein UK states 30g per High-Protein Bar serving. Once I have suitable options, I can compare the amount I would get from the portion I intend to eat.

Mistakes to avoid

  • Treating a category claim as an allergy claim

    ‘High protein’, ‘low sugar’ and ‘vegan’ describe different characteristics. Barebells UK’s Vegan Fudge Brownie contains wheat and soya and states that it may contain milk, peanuts, tree nuts and sesame.

    Check the exact bar’s ingredients and precautionary statement before comparing its nutrition information.

  • Assuming a non-peanut flavour has no nut warning

    Grenade identifies some peanut-containing flavours and says several products are made in a facility handling peanuts, nuts and other allergens. A flavour name cannot tell you what its full declaration says.

    Read the ingredients and any ‘may contain’ wording for the flavour you are buying.

  • Buying a multipack before checking the flavour

    An allergen statement for one flavour or pack should not be applied to another. Grenade advises checking the wrapper, including when older batches remain available.

    Inspect a current wrapper before committing to a multipack, and check the delivered bars before eating them.

    If the delivered formulation does not meet your requirements, you may be left with several bars you cannot use.

  • Choosing by the largest protein number first

    Myprotein UK states 30g of protein per serving for its High-Protein Bar, but the product contains milk protein and lists several possible trace allergens. That amount does not make it suitable for someone who must avoid those allergens.

    Compare protein per serving only among bars whose current declarations meet your avoidance requirements.

Brand and retailer references

These examples show why the exact product and flavour matter more than a range-wide description.

Grenade

Grenade sells several protein-bar flavours. Its Chocolate Chip Cookie Dough bar listed by Tesco Groceries provides 21g of protein per 60g bar.

  • The Tesco Groceries listing gives ingredients and an allergen statement for that Cookie Dough bar.
  • That bar contains milk and soya and may contain gluten, egg, nuts, peanuts and sesame. Grenade also identifies peanut-containing flavours; check each current wrapper.

PhD

PhD’s Smart Bar range uses a whey-protein centre. Its UK product page states 21g or 22g of protein per 64g bar for the flavours shown.

  • The page gives flavour-specific protein amounts for the examples shown.
  • Whey is milk-derived, so these bars are not an option for someone avoiding milk. Check the chosen flavour’s full declaration.

Myprotein

Myprotein UK lists both conventional and vegan protein snacks. Its High-Protein Bar states 30g of protein per serving.

  • The High-Protein Bar’s product information identifies milk protein among its ingredients.
  • That bar may contain wheat, barley, oats, egg, peanuts, nuts, sesame and sulphur dioxide. A separate vegan product needs its own allergen check.

Barebells

Barebells UK states 20g of protein for its Cookies & Cream bar and 15g for its Vegan Fudge Brownie bar.

  • The two product declarations allow shoppers to check the specific ingredients and warnings alongside the stated protein amounts.
  • Cookies & Cream contains milk. Vegan Fudge Brownie contains wheat and soya and may contain milk, peanuts, tree nuts and sesame.

Quest

Quest Nutrition describes its standard protein bars on its US site as dairy-based and gluten-free, with some bars providing up to 21g of protein.

  • The US range information identifies dairy as a protein source to consider when screening for milk.
  • Do not assume those US-range claims describe a UK retail pack. Check the exact UK product’s ingredients and allergen statement.

Tesco

Tesco Groceries lists protein bars from several brands, including peanut-containing products.

  • An individual product listing can provide ingredients and allergen information, as the Grenade Cookie Dough listing does.
  • A category listing is not an allergy filter. Check the individual product declaration and the pack you receive.

Questions about allergy labelling

Is a ‘high protein’ label enough to choose a bar when I have a food allergy?

No. Protein content does not establish whether a bar meets your allergen requirements. Check the exact flavour’s ingredients and precautionary statement first, then compare protein per bar or serving among suitable options.

Does ‘vegan’ mean a protein bar is suitable for a milk allergy?

No. Barebells UK’s Vegan Fudge Brownie states that it may contain milk. Read the product’s current allergen declaration and apply your individual avoidance advice rather than relying on the vegan label.

Why check ‘may contain’ when my allergen is not an ingredient?

The Food Standards Agency explains that precautionary allergen labelling communicates possible unintentional presence of an allergen, including through a ‘may contain’ statement. Whether a particular warning is compatible with your needs depends on your allergen and individual avoidance advice.

Can I use a brand’s general allergy advice instead of checking the wrapper?

No. General advice can point you towards relevant ingredients or warnings, but the exact flavour and current pack need checking. Grenade advises customers to inspect the wrapper because older batches may still be available.
