Gluten-free snack shoppers
Look for a gluten-free statement on the exact bar, then check separately for milk, peanuts and other nuts if those matter too. Gluten-free does not mean free from every allergen.
Who is choosing a bar?
The label that matters most depends on what you need to avoid, including when you are sharing snacks with someone whose requirements differ from yours.
Dairy-free or vegan snack shoppers
A vegan or dairy-free description addresses a different requirement from gluten or nut avoidance. Read the ingredients and allergen information for the flavour you plan to eat.
People managing a food allergy
Check the current pack for the ingredient you avoid, highlighted allergens and precautionary wording such as “may contain”. A category description cannot settle whether an individual bar meets your needs.
What should you check?
Start with the exclusion that matters to you, then screen the remaining allergens and compare nutrition using the serving size on each bar.
| Priority | What to check | Your needs |
|---|---|---|
| Gluten | Look for a gluten-free statement on the exact product. Check the flavour-specific ingredients and any precautionary wording. | I need a bar labelled gluten-free, but I may also need to check milk and nuts. Tesco’s gluten-free Nature Valley Protein Variety Pack, for example, lists peanuts and milk ingredients. |
| Milk and other allergens | Read the full ingredients, highlighted allergens and “may contain” statement. The Food Standards Agency describes precautionary allergen labelling as a warning about possible unintended presence. | If I am avoiding milk, peanuts, soya or nuts, a claim about gluten or vegan suitability does not answer that separate question. |
| Vegan suitability | Check the vegan designation, then screen wheat and other allergens separately. Myprotein’s Vegan Carb Crusher listing identifies cereals containing gluten and warns that it may contain milk, peanuts and nuts. | I want a plant-based TV snack, but I cannot assume “vegan” also means gluten-free or nut-free. |
| Nutrition per bar | Compare protein, sugars and the labelled serving size on the precise flavour. Check the ingredients if sweeteners matter to you. | For an evening snack, I want to compare the bars I would actually eat, rather than judge them by “protein” or “low sugar” wording alone. |
| Multipack flavour | Confirm the ingredients and allergen statements for every flavour in the pack. Recheck the physical pack when you buy it. | If several people will share the snacks, each flavour needs to fit the requirements of whoever might eat it. |
Common label mistakes
-
Treating vegan as another word for gluten-free
Vegan bars can contain gluten: Barebells says its newer vegan bars contain wheat protein, while Myprotein’s Vegan Carb Crusher listing identifies cereals containing gluten.
If gluten avoidance matters, find a gluten-free statement for the exact bar and check its ingredients and precautionary wording.
-
Assuming gluten-free also excludes milk and nuts
A gluten-free statement does not address unrelated allergens. Tesco’s Nature Valley Protein Variety Pack is labelled gluten-free but lists peanuts and milk ingredients.
Screen milk, peanuts and other allergens separately, especially when sharing a snack.
-
Choosing by a sugar claim alone
Sugar wording does not establish allergen suitability or tell you the protein and sugars in the serving you will eat.
Read the allergen panel first, then compare nutrition per labelled bar and check its ingredients.
-
Buying a multipack before checking its flavours
Ingredients and allergen statements can differ between flavours and product formats within a range.
Check each flavour’s current label before choosing a larger pack.
If a flavour contains an ingredient you need to avoid, you may be unable to use those bars.
Brand and retailer references
These examples show why claims must be checked by product and flavour; a statement about one range does not apply to every bar from the same brand.
Grenade
Grenade markets its Carb Killa range as protein bars with dessert-style flavours.
- Grenade says Carb Killa bars contain up to 24g protein per bar and less than 2g sugar.
- Grenade’s UK FAQ says products other than its Oreo bars have no gluten-containing ingredients but are made in a factory handling wheat and cannot be certified gluten-free. Check the exact product and flavour.
PhD
PhD’s UK Smart Bar range lists both Smart Protein Bar and Smart Plant Protein Bar.
- PhD’s EU listing describes Smart Bar Plant as suitable for dairy-free, egg-free, gluten-free, wheat-free and vegan diets.
- That detailed listing is for the EU market. Check the current UK pack and flavour’s ingredients and allergen panel before relying on those statements.
Myprotein
Myprotein’s bar range includes Vegan Carb Crusher.
- Myprotein describes Vegan Carb Crusher as suitable for vegans.
- Its UK listing identifies cereals containing gluten and warns that it may contain milk, peanuts and nuts. Vegan suitability does not settle those separate requirements.
Barebells
Barebells offers vegan as well as other protein-bar formats.
- Its vegan Fudge Brownie bar is an example for shoppers seeking a vegan format.
- Barebells lists gluten-containing cereals, soybeans and wheat for that bar, with possible traces of milk, peanuts, tree nuts and sesame. Its FAQ also says its newer vegan bars contain gluten.
Tesco
Tesco’s protein-bar listings illustrate different free-from claims on individual products, rather than one claim covering its whole range.
- Its listings describe the Nature Valley Protein Variety Pack as gluten-free and nākd Cherry Protein Bars as gluten-free and dairy-free.
- The Nature Valley listing includes peanuts and milk ingredients; the nākd Cherry listing warns that it may contain soya and nuts. Check each product separately.
Quest
Quest’s Apple Pie bar information describes a US-market product.
- Quest’s US ingredient list identifies milk protein, almonds and butter, giving shoppers specific ingredients to screen for that product.
- Use the UK pack’s ingredients and allergen statements for a UK purchase rather than assuming the US product information describes the bar you are buying.
Protein bars and flapjacks on Joybuy
These TV-snack options include a protein flapjack and several protein bars. Compare the exact pack’s free-from statements and allergen panel before choosing; a flavour name or protein-bar description is not an allergen guarantee.

Grenade Soft Core Double Chocolate, 12 × 50g
A double chocolate protein-bar option if that flavour appeals for a TV snack. This is a pack of twelve 50g bars; check the Soft Core pack itself for milk, soya, gluten-related statements and precautionary allergens rather than applying claims about Grenade’s Carb Killa range.

Nature Valley Protein Peanut & Chocolate, 4 × 40g
A peanut and chocolate bar to consider for an evening snack. The pack contains four 40g bars; check this product’s own gluten-free statement, ingredients and precautionary allergen wording rather than relying on details for a different Nature Valley variety pack.
Questions about free-from labels
Does “free from” mean a bar is suitable for every allergy?
No. A free-from claim concerns the allergen or intolerance it names, not every other ingredient. The Food Standards Agency describes such a claim as a guarantee for the stated allergy or intolerance; check the exact bar’s ingredients and any precautionary statement for your other requirements.
Are vegan protein bars automatically gluten-free?
No. Myprotein’s Vegan Carb Crusher listing identifies cereals containing gluten, and Barebells says its newer vegan bars contain wheat protein and gluten. If you need to avoid gluten, check for a gluten-free statement on the specific bar.
Can a gluten-free protein bar contain milk or peanuts?
Yes. Tesco’s gluten-free Nature Valley Protein Variety Pack lists peanuts and milk ingredients. Check those allergens separately, even when gluten-free is clearly stated.
Does a low-sugar claim settle which bar to buy?
No. It does not answer an allergen question or describe every nutrition value. Compare the protein and sugars per labelled bar, then read the ingredients and allergen panel for the flavour you intend to buy.
Should I check the label again when buying the same bar?
Yes. Check the current pack, particularly if you switch flavours or buy a multipack. Ingredients and precautionary allergen statements can differ across products in the same range.
