Choose a post-gym protein bar by the exact allergens you need to avoid, then compare protein per bar. A vegan label does not settle gluten, soya or cross-contact concerns, as Barebells’ Fudge Brownie listing illustrates. A gluten- and dairy-free bar is not necessarily nut-free: Tesco labels nākd Cocoa Hazelnut gluten- and dairy-free, while Joybuy lists peanuts and hazelnuts in the multipack ingredients.
Who needs a closer label check?
Gym-goers avoiding a specific allergen
Check the exact flavour’s ingredients and any ‘may contain’ statement before comparing its protein content. GOV.UK distinguishes allergens used as ingredients from other ingredients; Food Standards Agency guidance describes precautionary allergen labelling as a warning about possible cross-contact.
Vegan shoppers looking for a protein snack
A vegan bar can still contain allergens you need to avoid. Barebells lists gluten-containing cereals and soya in its Vegan Fudge Brownie bar, alongside a warning for possible milk, peanut, tree nut and sesame traces.
Shoppers avoiding gluten and dairy who can eat nuts
A gluten- and dairy-free claim may meet those two requirements without meeting a nut-free requirement. Tesco describes nākd Cocoa Hazelnut as gluten- and dairy-free; Joybuy’s multipack ingredient listing includes peanuts and hazelnuts.
What should you check before choosing?
Start with the ingredients and allergen warnings for the exact flavour. Once those fit your requirements, compare what one bar contributes to your intended snack.

What to check |
Your needs |
| Specific allergens |
Read the exact flavour’s ingredients and any ‘may contain’ statement. GOV.UK says the 14 regulated allergens must be declared as allergens when used as ingredients; Food Standards Agency guidance addresses warnings about possible cross-contact. |
I need to rule out my particular allergen, not just find a bar described as ‘free from’. |
| Protein per bar |
Compare the stated grams per bar and the serving size, rather than relying on ‘protein bar’ in the name. Check whether one bar makes the contribution you want alongside other food. |
If this is my post-gym snack, I want to know what one bar contributes, not just what the whole multipack contains. |
| Vegan and free-from claims |
Check each claim separately against the ingredients. Barebells lists gluten-containing cereals and soya in its Vegan Fudge Brownie bar and warns of possible traces of several other allergens. |
A plant-based bar may suit my preferences, but I still need to check every ingredient and warning relevant to me. |
Common free-from mistakes
-
Treating ‘vegan’ as an allergy check
Vegan status does not rule out wheat, soya or peanuts. Barebells’ Vegan Fudge Brownie listing also warns of possible milk, peanut, tree nut and sesame traces.
Write down the ingredients you need to avoid and check both the ingredient list and any ‘may contain’ wording for the exact flavour.
-
Assuming gluten- and dairy-free also means nut-free
Tesco describes nākd Cocoa Hazelnut as gluten- and dairy-free, while Joybuy’s ingredient listing for its multipack includes peanuts and hazelnuts.
Use a free-from claim as a filter for the named ingredient only, then read the full label for other allergens.
-
Judging protein content by the category name
‘Protein bar’ does not tell you how many grams one bar provides. A multipack’s size also does not describe a single serving.
Compare the protein stated per bar with what you want from this snack and the other food you plan to eat.
Brand ranges and label differences
These examples show why a brand name or range-wide description cannot replace the label for a particular bar.
PhD
PhD lists both plant-based Smart Plant bars and a standard Smart Bar with a whey-protein centre.
- Joybuy’s PhD Smart Plant Vanilla Fudge listing states 20g protein per 64g bar.
- A whey-based Smart Bar does not meet a dairy-free requirement; check the exact Smart Plant flavour’s ingredients for any other exclusions.
Myprotein
Myprotein’s Vegan Carb Crusher is a plant-based bar range.
- The range offers a vegan option for shoppers avoiding animal-derived ingredients.
- Myprotein’s allergen information flags cereals containing gluten in the ingredients and says the bar may also contain milk, peanuts and nuts.
Barebells
Barebells offers a Vegan Fudge Brownie bar, but its vegan description is not an allergen-free claim.
- The named bar gives shoppers a plant-based option to assess against their own requirements.
- Barebells lists gluten-containing cereals, soya and wheat, with possible traces of milk, peanuts, tree nuts and sesame.
Grenade
Grenade sells protein bars in multiple flavours, so the relevant allergen check is flavour-specific.
- Grenade directs shoppers to product ingredients and packaging for allergen information.
- Grenade specifically warns people with a peanut allergy to avoid its Peanut Nutter, White Chocolate Salted Peanut and Peanut Butter & Jelly flavours because they contain peanuts.
Tesco
Tesco’s listings include bars with different vegan and free-from descriptions.
- Tesco describes nākd Cocoa Hazelnut as gluten-free, dairy-free and suitable for vegans.
- Tesco’s Misfits Caramel Fudge listing warns that it may contain gluten-containing cereals, milk, nuts and peanuts; check each listed product separately.

Questions about free-from protein bars
Does vegan mean a protein bar is free from milk, nuts and gluten?
No. Vegan describes the ingredients’ animal-derived status, not every allergen or possible cross-contact. Barebells lists gluten-containing cereals and soya in its Vegan Fudge Brownie bar and warns of possible traces of milk, peanuts, tree nuts and sesame.
What should I check on a protein-bar label if I avoid an allergen?
Read the exact flavour’s ingredient list and any ‘may contain’ statement for the allergen you avoid. GOV.UK says the 14 regulated allergens must be declared as allergens when used as ingredients; Food Standards Agency guidance explains that precautionary labelling addresses possible unintended presence through cross-contact.
Does gluten- and dairy-free mean a bar is nut-free?
No. Tesco describes nākd Cocoa Hazelnut as gluten- and dairy-free, while Joybuy lists peanuts and hazelnuts in its multipack ingredients. Check nut ingredients separately, even when the other free-from claims meet your needs.
Is any protein bar enough on its own for a post-gym snack?
The category name alone cannot answer that. Compare the protein stated per bar—not per multipack—with the contribution you want from your snack and the other food you plan to eat, after confirming the bar fits your ingredient requirements.
