What should you check?
Start with any allergen that must be avoided; compare dietary claims and nutrition figures only after the individual bar meets that requirement.
| Priority | What to check | Your needs |
| Allergens |
Read the current pack’s ingredient list and “may contain” statement for the exact flavour. Check the wrapper again before sharing a bar from a multipack. |
I’m serving someone who needs to avoid a particular allergen, so I need to check both ingredients and cross-contact warnings. The Food Standards Agency describes “may contain” labelling as a warning that a regulated allergen could be unintentionally present. |
| Dietary claims |
Look for the claim that matches the requirement. Check wheat ingredients on vegan bars and the exact pack when choosing a gluten-free product. |
A plant-based bar suits my preference, but I cannot assume it is gluten-free or suitable for someone with a milk or nut allergy. For gluten avoidance, I need the gluten-free claim on the bar being bought. |
| Nutrition panel |
Compare protein and sugars on the same basis, such as per bar. Read the serving size and any polyol warning. |
If I’m comparing protein and sugars for an evening snack, the values for the portion I’ll eat matter more to me than figures shown on different serving bases. |
| Sharing at the event |
Keep bars in their wrappers until guests have checked them. Do not rely on an older online listing in place of the pack. |
I want guests to see the information for the individual bar they are offered, particularly if I bought several flavours ahead of Bonfire Night. |
Brand and product-line references
These examples show why the exact product and flavour matter; a brand name alone does not establish allergen suitability.
Grenade
Grenade’s Chocolate Chip Salted Caramel bar is a protein-focused option, not a general free-from choice.
- Grenade states 20 g protein and 1.4 g sugar per 60 g bar.
- The bar contains milk and soy, may contain gluten, peanuts and nuts, and carries a polyol-consumption warning.
PhD
PhD’s Smart Bar line includes whey-protein bars; check the chosen flavour rather than applying one flavour’s figures across the line.
- PhD lists 21 g protein and 1.2 g sugars per 64 g Chocolate Brownie bar.
- A whey-protein centre makes this line unsuitable as a default choice for dairy avoidance.
Myprotein
Myprotein’s Vegan Carb Crusher is labelled suitable for vegans, but that claim does not cover every allergen requirement.
- The product description lists 15 g plant-based protein and 9 g fibre.
- It contains wheat ingredients, may contain milk, peanuts and nuts, and is described by Myprotein as unsuitable for people with peanut or nut allergies.
Barebells
Barebells flavours need individual label checks, particularly where milk, nuts or precautionary warnings matter.
- Tesco lists 16 g protein per 55 g Barebells Soft Cinnamon Bun bar.
- That flavour lists milk proteins and soy lecithin and may contain cereals containing gluten, peanuts, nuts and sesame. Barebells also says its protein bars contain nuts or may contain traces of nuts.
Quest
Quest describes a gluten-free protein-bar collection made with dairy-based proteins.
- The collection gives shoppers a gluten-free product line to investigate.
- The reviewed Quest collection information is not a UK product listing; confirm the exact UK pack and its allergen information before choosing a bar for a guest.

Questions about free-from bars
Does vegan mean a protein bar is free from milk, gluten and nuts?
No. Myprotein Vegan Carb Crusher is labelled suitable for vegans, but contains wheat ingredients, may contain milk, peanuts and nuts, and is described by Myprotein as unsuitable for people with peanut or nut allergies. Check the exact bar against the requirement.
What does “gluten-free” mean on a UK protein bar?
The Food Standards Agency states that food sold to the final consumer may be labelled “gluten-free” when it contains no more than 20 mg/kg gluten. That claim does not also establish that the bar is vegan, dairy-free or nut-free, so read the rest of the label.
What does “may contain” tell a Bonfire Night guest?
The Food Standards Agency describes it as precautionary labelling that an allergen could be unintentionally present. If that allergen matters to the guest, include the warning when checking whether the bar meets their requirements; do not look only at deliberate ingredients.
Is a supermarket product page enough when buying bars in advance?
No. Tesco advises that products can be reformulated and their ingredient and allergen information can change. Read the label on the physical pack you intend to serve.
Does a lower-sugar bar need any other checks?
Yes. Grenade warns that its Salted Caramel bar contains more than 10 g polyols per 100 g and that excessive consumption may have a laxative effect. Read the chosen bar’s serving information, warnings and allergen label alongside its sugars figure.
