Shoppers avoiding a named allergen
Check the ingredients and any precautionary “may contain” statement on each flavour and pack. A vegan or general free-from claim does not answer a question about every allergen.
Who needs to check what?
Vegan or dairy-free snack buyers
Look for the relevant dietary claim, then check separately for ingredients such as soya, peanuts and wheat, and for cross-contact warnings that matter to you.
Shoppers avoiding gluten
Check the gluten claim on the specific bar. If you also avoid milk or particular sweeteners, assess those separately rather than assuming a gluten-free claim covers them.
What matters when choosing?
Set your ingredient requirements first, then compare the whole bar’s nutrition and the pack you would actually buy.
| Priority | What to check | Your needs |
|---|---|---|
| Named allergens | Read the exact flavour’s ingredients, emphasised allergens and any “may contain” statement. The Food Standards Agency explains that precautionary wording communicates possible unintended allergen presence. | I need to avoid a particular allergen, so a broad free-from claim is not enough to decide whether this pack fits. |
| Vegan and dairy-free claims | Check the dietary claim separately from the protein ingredients and cross-contact statement. PhD’s Smart Plant Salted Caramel lists soya and peanut paste; Barebells Vegan Fudge Brownie lists wheat and soya. | A plant-based afternoon snack appeals to me, but I may also need to avoid an ingredient that a vegan bar can contain. |
| Gluten avoidance | Confirm the claim for the individual flavour, then check milk and other ingredients independently. Quest describes its protein-bar range as gluten-free but says it uses dairy-based proteins. | Gluten is my main concern; whether I can have dairy is a separate decision. |
| Nutrition per bar | Compare bar weights alongside the stated protein, sugars and saturated fat per serving. Read the polyol line and any serving warning. | For my afternoon portion, I want to compare the whole snack rather than choose by a front-of-pack protein claim alone. |
| Finding candidates | Use a retailer’s dietary category to narrow your search, then inspect each product page or pack. A category can include different kinds of snack bar. | I want something practical to carry, without treating a shop filter as confirmation about a named allergen. |
Common buying mistakes
-
Treating “vegan” as an all-allergen claim
PhD Smart Plant Salted Caramel contains soya and peanut paste. Barebells Vegan Fudge Brownie contains wheat and soya and lists possible traces of other allergens.
Write down what you avoid, then check the ingredients and precautionary statement for the exact flavour.
-
Judging the snack by its protein claim alone
Protein content does not tell you the bar’s portion size, sugars or saturated fat.
Compare the nutrition panels on the same per-bar basis, alongside the ingredients you need to avoid.
-
Overlooking polyols
Some bars list sugar alcohols or carry a laxative-effect warning for excessive consumption. PhD lists 16g polyols per 64g Smart Plant Salted Caramel bar.
Read the sweeteners and pack warning, particularly if these ingredients have affected you before.
-
Using a shop filter as the final label check
A milk-free or protein-bar category can contain different products; the category name does not establish the ingredients of each flavour.
Use filters to find candidates, then check the current individual product information or physical pack.
Brand and retailer references
These examples show why the exact bar matters more than a brand-wide assumption; they do not establish that every flavour has the same ingredients.

Questions about free-from bars
Does vegan mean a protein bar is free from milk, gluten and nuts?
No. A vegan claim concerns animal-derived ingredients, not every allergen or possible cross-contact. PhD’s vegan Smart Plant Salted Caramel contains soya and peanut paste; Barebells Vegan Fudge Brownie contains wheat and soya and says it may contain milk, peanuts, tree nuts and sesame. Check the exact pack for the ingredients you avoid.
What does “may contain” mean on a protein bar?
It is a precautionary statement about possible unintended allergen presence, rather than an ingredient deliberately added to the recipe. The Food Standards Agency describes such wording as a way to communicate potential presence, including through cross-contact; read it alongside the ingredient list for your particular avoidance need.
Is a low-sugar claim enough to choose an afternoon bar?
No. Compare nutrition per whole bar, including the stated protein, sugars and saturated fat, as well as portion weight. Also check for polyols and any serving warning if those ingredients matter to you.
Why do some bars carry a laxative-effect warning?
Some bars containing polyols carry a warning about excessive consumption. Grenade’s Cookie Dough and Barebells Vegan Fudge Brownie carry such warnings, while PhD lists 16g polyols per Smart Plant Salted Caramel bar. Read the guidance on the pack you buy.
