Gluten-free shoppers managing other allergens
Check the exact bar for peanuts, tree nuts, milk and soya as well as its gluten-free claim. A claim about gluten does not answer questions about those other ingredients.
Who needs to check what?
Vegan shoppers ordering snack bars
Look for vegan status on the individual flavour, then check separately for any ingredients or precautionary statements relevant to you. Vegan does not mean nut-free or gluten-free.
Shoppers comparing protein per bar
Use the nutrition declaration for the portion you plan to eat, alongside the ingredient list. Protein-focused bars can still contain ingredients you need to avoid.
What matters when choosing a bar?
Start with the required exclusion, check the exact flavour’s allergen information, then compare portion sizes and nutrition among bars that meet those requirements.
| Priority | What to check | Your needs |
|---|---|---|
| Specific exclusion | Look for the claim that matches your requirement, such as gluten-free or dairy-free. Read the exact flavour’s ingredients rather than relying on a search filter or brand name. | I need the bar to exclude a particular ingredient; a different free-from claim does not settle that choice. |
| Other allergens | Check declared ingredients and any ‘may contain’ statement for nuts, peanuts, milk and soya where relevant. Recheck the delivered wrapper. | A gluten-free or vegan bar still needs a separate check against every allergen I avoid. |
| Nutrition per bar | Compare protein, fibre and sugars on the same serving basis. Nature Valley UK lists around 10g protein and 4g fibre per 40g Protein Variety bar; TREK lists 10g plant protein per Original Oat bar. | For a bar I can take to work or while travelling, I want to know what the portion I will eat contains—not just what the front of the pack highlights. |
Common buying mistakes
-
Reading ‘gluten-free’ as an all-allergen claim
A gluten-free bar can contain other allergens. The Joybuy listing for Nature Valley Protein Peanut & Chocolate declares peanuts, soya and milk, and says it may contain nuts.
Check the ingredient list and precautionary statement for the exact flavour against everything you need to avoid.
-
Assuming a vegan bar is nut-free
Vegan status concerns animal-derived ingredients; it does not rule out peanuts, tree nuts or soya.
Check vegan status and your allergen exclusions separately before adding a bar to the order.
-
Comparing protein figures without the portion size
Nature Valley UK gives around 10g protein per 40g Protein Variety bar, while TREK gives 10g plant protein for Original Oat. The portions and products are different, so the figures alone do not settle which bar meets your dietary requirements.
Read the per-bar nutrition panel for the flavour you intend to buy, then check its ingredients.
-
Using an old listing instead of the delivered pack
A saved product page is not the wrapper of the bar delivered with your order.
Check the current listing before checkout and the exact pack when it arrives, particularly where an ingredient must be avoided.
Brand ranges to compare
Brand ranges contain different flavours and formats. Use these references to narrow your search, then assess the individual product.
nākd.
Fruit-and-nut bars are one route for shoppers seeking vegan, gluten-free and dairy-free options, according to nākd.’s range information.
- The brand describes its fruit-and-nut bars as vegan and free from gluten, wheat and dairy.
- Individual bars can contain nuts. Joybuy’s Cocoa Orange listing, for example, declares cashews and carries precautionary statements for other ingredients.
TREK
TREK Original Oat is a vegan, gluten-free oat-bar option for shoppers comparing protein per bar.
- TREK states that Original Oat provides 10g plant protein per bar.
- Check the ingredients and precautionary allergen statement on the specific TREK flavour; Original Oat contains soya ingredients.
Nature Valley
The Protein Variety bars give gluten-free shoppers a stated per-bar protein and fibre amount to compare.
- Nature Valley UK lists around 10g protein and 4g fibre per 40g Protein Variety bar.
- Gluten-free status does not make the range suitable for every allergen exclusion; check the chosen flavour for peanuts, soya, milk and nuts.
Eat Natural
Eat Natural’s UK gluten-free filter offers a starting point for comparing different bar formats.
- Shoppers can browse products within a dedicated gluten-free range.
- Ingredients differ by flavour, so check vegan status and any other required exclusion on the individual bar.
Graze
Graze has snack formats including Oat Boost flapjacks.
- Graze says all its snacks are vegetarian and most are vegan.
- ‘Most are vegan’ does not identify which bar meets your requirement; check each product’s current declaration.
Alpen
Alpen’s cereal-based range calls for a product-specific check when cereals are part of your exclusion.
- Alpen states that its products contain wheat, barley or oats, giving shoppers a clear reason to inspect the particular product.
- Do not infer gluten-free suitability from a generic free-from search result; check the exact bar’s declaration.

Questions about free-from bars
Does gluten-free mean a snack bar is nut-free?
No. Gluten-free does not rule out peanuts or tree nuts. Joybuy’s listing for Nature Valley Protein Peanut & Chocolate declares peanuts and says it may contain nuts, so check the exact bar against your requirements.
What should I check before placing an order if I have a food allergy?
Read the exact product’s ingredients, declared allergens and any precautionary allergen statement before checkout. GOV.UK and Food Standards Agency guidance says food businesses must provide allergen information; use the information for the particular bar and check its delivered wrapper too.
Should I check the wrapper after delivery?
Yes. Compare the delivered product’s ingredients and allergen statements with what you need to avoid, even if you checked its online listing before ordering.
Can a vegan bar also be gluten-free and contain protein?
Yes, for some individual products: TREK describes Original Oat as vegan and gluten-free and states that it provides 10g plant protein per bar. Check its soya ingredients and precautionary allergen statement, and do not assume another TREK flavour has the same declarations.
Can I assume an Alpen bar is gluten-free?
No. Alpen states that its products contain wheat, barley or oats. If you require a gluten-free bar, look for an explicit product-specific claim and check the current pack rather than relying on a general search result.
