Coeliac shoppers carrying separate portions
For a bar taken to work, on a journey or after exercise, you need to check the current pack’s gluten information as well as whether each portion is separately wrapped.
Who is this for?
Shoppers comparing protein and allergens
Protein per bar matters to your choice, but it does not establish gluten suitability. Check the exact bar’s label and any other allergens relevant to you alongside its stated protein amount.
Mixed-box buyers
A selection box offers different flavours, but each included bar may have different ingredients or allergen wording. Check the current contents and every flavour before treating the box as a coeliac grab bag.
What to check before choosing
Start with gluten information on the exact pack, then compare how the bars are portioned and what each bar contains.
| Priority | What to check | Your needs |
|---|---|---|
| Gluten information | Look for a gluten-free statement applying to the exact pack. Read the ingredients and precautionary allergen wording; Coeliac UK says a ‘may contain’ statement indicates an unavoidable cross-contamination risk identified by the manufacturer. | I need to judge the bar I will actually receive, rather than relying on a high-protein, vegan or brand-level claim. |
| Portable portions | Check the bar count, weight per bar and whether individual wrapping is explicitly stated. Tesco describes its Nakd Peanut Butter Protein Bars 3 x 45g pack as individually wrapped. | I want to carry one bar at a time and check its wrapper before eating. |
| Protein and other ingredients | Compare protein per bar at the stated serving size, then read the full allergen list and any sweetener or polyol warnings. Protein content alone says nothing about gluten suitability. | A particular protein amount may matter to me, but I also need to account for other allergens and the pack’s serving advice. |
| Mixed flavours | Confirm the current flavour list and check each included bar. Grenade says flavours in its Protein Bar Selection Box can vary, while its allergy advice mentions wheat and traces of gluten. | If I buy a variety box, I need the allergen information for every flavour, not just a description of the box. |
Selection-box and allergen pitfalls
-
Choosing a mixed box for its protein claim
Flavours can differ within a box. Grenade’s Protein Bar Selection Box says flavours may vary and carries precautionary wording about wheat and traces of gluten.
Check the exact box and every included flavour instead of using a protein or low-sugar claim as a shortcut.
-
Assuming one gluten-free product covers a whole range
Myprotein describes its Pulsin Keto Bar as gluten-free, but lists wheat flour among the ingredients of its separate Protein Bar Selection Box.
Make the decision for the specific product and pack you plan to buy, not another item sold by the same retailer.
-
Checking gluten but overlooking other allergens
A gluten-free statement does not tell you whether a bar contains nuts, milk or soya. The cited Nakd Peanut Butter and KIND Dark Chocolate Nut bars have nut ingredients, for example.
After checking gluten information, read the complete ingredient and allergen statement for any other ingredients you need to avoid.
Relevant brand and retailer references
Brand ranges can contain products with different gluten information, so these examples are starting points for checking an exact pack, not brand-wide suitability statements.
Grenade
Grenade offers protein bars and a selection box with varying flavours.
- The selection-box format provides flavour variety.
- Grenade’s current selection-box allergy advice says the bars may contain wheat and traces of gluten; do not use that box as a default coeliac grab bag.
PhD
PhD lists Smart Bar and Smart Plant Protein Bar multipacks on its UK site.
- PhD states that its Smart Bar contains 20g protein and less than 2.5g sugar per bar.
- Those figures do not establish gluten suitability; check the exact UK flavour and pack before choosing it for coeliac shopping.
Myprotein
Myprotein sells different bar types, including individual product ranges and selection boxes.
- Its Pulsin Keto Bar listing describes that specific product as gluten-free.
- Its Protein Bar Selection Box lists wheat flour among its ingredients. A claim for one product cannot be applied to the box.
Quest
Quest describes its Protein Bars as gluten-free on its US range page.
- The US page states that Quest OG Protein Bars contain up to 21g protein per bar.
- For a UK purchase, check the exact pack’s formulation and label rather than transferring a US-range statement to it.
Barebells
Barebells offers several bar ranges, including vegan varieties.
- Its range gives shoppers different bar types to assess individually.
- Barebells says its Vegan Caramel Choco Chip, Vegan Fudge Brownie and Vegan Caramel Peanut bars contain wheat protein and gluten. Vegan status is not a gluten-free statement.
Tesco
Tesco is a retailer whose product listings can help compare named multipacks.
- Tesco describes its Nakd Peanut Butter Protein Bars 3 x 45g pack as gluten-free and individually wrapped.
- Its cited KIND Dark Chocolate Nut Protein Bars 12 x 50g listing is a Marketplace item; check the seller and delivery arrangement as well as the exact product information.

Frequently asked questions
What does ‘gluten-free’ mean on a UK protein bar?
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. ‘Very low gluten’ is a different designation, with a limit of 100 mg/kg, so read which wording appears on the exact pack.
Can a high-protein or vegan claim establish coeliac suitability?
No. Neither claim tells you whether the exact bar is suitable for a gluten-free diet. Check its gluten-free statement, ingredients and precautionary allergen wording; Barebells says several of its vegan bars contain wheat protein and gluten.
What should I do with ‘may contain wheat’ or ‘may contain gluten’ wording?
Do not treat that pack as a default coeliac choice. Coeliac UK explains that a ‘may contain’ statement means the manufacturer has identified an unavoidable risk of gluten cross-contamination; contact the manufacturer if you need clarification about a particular product.
Why check every bar in a selection box?
Flavours can change and their ingredient and allergen statements can differ. Grenade says the flavours in its Protein Bar Selection Box may vary, so check the current box and each included flavour rather than assuming one statement covers them all.
Does the Crossed Grain Trademark help when comparing packs?
Yes. Coeliac UK says products displaying its Crossed Grain Trademark hold gluten-free analysis certificates and have undergone independent manufacturing audits. Check that it applies to the exact product, then read the pack for any other allergens relevant to you.
