Prioritise the ingredient or allergen you need to avoid, then compare protein per bar with the rest of what you plan to eat after training. Vegan does not mean gluten-free or nut-free, and gluten-free does not rule out milk or nuts; check the exact flavour’s ingredients and any “may contain” wording before buying.
If you must avoid milk, gluten-containing cereals, peanuts or tree nuts, start with the exact bar’s ingredients and precautionary wording. A broad vegan or gluten-free claim does not answer every allergen question.
Check the plant-based or dairy-free claim alongside protein per bar. Soya, wheat and peanut information still matters: suitability for one dietary requirement does not establish suitability for another.
Look for an explicit gluten-free claim on the product you intend to buy. Then check its other allergens and protein amount to decide how it fits with the rest of your food after training.
Set your non-negotiable ingredient exclusions before comparing protein amounts or other nutrition information.
| Priority | What to check | Your needs |
|---|---|---|
| Allergens | Read the exact flavour’s ingredients and highlighted allergens. Check “may contain” wording separately: the Food Standards Agency explains that it communicates possible unintended allergen presence. | I need to know whether both the ingredients and any cross-contact warning fit the allergens I avoid. |
| Free-from claims | Check each required claim independently. Barebells says some of its newer vegan bars contain wheat protein and therefore contain gluten; a gluten-free label does not establish that a bar is dairy-free or nut-free. | A vegan or gluten-free label helps me narrow the choice, but I still need to check my other exclusions. |
| Protein per bar | Compare grams per bar, not just the product name, with the rest of your food after exercise. The International Society of Sports Nutrition’s 2017 position stand discusses 20–40g, or around 0.25g/kg, as general protein amounts around exercise; it is not a requirement for every bar. | Will this bar provide the amount of protein I want from a snack, or will it be one part of a larger meal? |
| Other pack warnings | Read the nutrition information and any polyol warning on the current pack, particularly if you might eat more than one serving. | Before choosing a lower-sugar bar, I want to know what other ingredients and warnings come with it. |
Vegan bars can still contain wheat, soya or peanuts, and may carry precautionary statements for other allergens. Barebells, for example, says some newer vegan varieties contain wheat protein and gluten.
Decide which ingredients you need to avoid, then check the exact flavour’s ingredients and “may contain” wording before comparing protein amounts.
Protein amounts differ by product. Tesco lists 7.2g per 45g Nakd Cocoa Hazelnut bar, while Barebells lists 15g for its Vegan Salty Peanut bar. Neither figure describes every product from those brands.
Compare protein per bar with what you plan to eat after training, while keeping your ingredient exclusions in view.
The Food Standards Agency distinguishes precautionary allergen labelling from ingredients: it communicates possible unintended presence of an allergen.
If you have an allergy, assess that wording separately from the ingredients list and follow the avoidance advice given by your clinician or allergy specialist.
These product-specific examples show why a brand name alone cannot establish which free-from requirements a bar meets.
A conventional protein-bar example for shoppers comparing protein amount alongside allergen information.
Its Smart Plant Salted Caramel bar illustrates a vegan and dairy-free route.
Its Vegan Carb Crusher illustrates why a vegan product still needs an individual allergen check.
Its vegan range includes bars with different ingredient considerations.
Its listings illustrate how gluten-free and dairy-free claims can differ between products.
These bars offer different flavours and pack sizes to assess against your ingredient exclusions and intended post-workout snack.

If you are looking for a vegan or gluten-free flapjack, confirm both claims on this exact pack. The pack contains 3 x 50g flapjacks; check its soya information and any “may contain” wording against your requirements.

For gluten avoidance, confirm the claim on the exact bar rather than relying on its protein-bar name. This is a pack of 4 x 40g bars; check the milk, soya and nut information if any of those ingredients matter to you.

The peanut-butter flavour makes peanut ingredients an immediate check for anyone avoiding them. The pack contains 3 x 42g bars; read its full allergen information, and do not assume a gluten-free or vegan claim.

Compare this Oreo-flavour bar’s protein information with its allergen information rather than treating it as a broadly free-from option. The pack contains 4 x 60g bars; check this flavour’s milk, wheat and soya information, any “may contain” wording and polyol warning.
No. A vegan claim does not address gluten or nuts. Barebells says some newer vegan bars contain wheat protein and gluten, while its Vegan Salty Peanut is a peanut-flavour product; check the exact bar’s ingredients and warnings.
No. Tesco lists its KIND Caramel Nut bar as gluten-free while naming milk among its allergens. Check each free-from requirement separately on the product you intend to buy.
Compare protein per bar with the rest of your food after exercise rather than expecting every bar to provide the same amount. The International Society of Sports Nutrition’s 2017 position stand discusses 20–40g, or around 0.25g/kg, as general protein amounts around exercise; it does not make that figure a requirement for an individual bar.
It is precautionary allergen wording about possible unintended allergen presence, as explained by the Food Standards Agency. For an allergy, assess it separately from the ingredients list and follow your clinician’s or allergy specialist’s avoidance advice.
Check the current pack’s ingredients list and any precautionary statement. The Food Standards Agency says allergens present in UK prepacked food must be emphasised each time they appear in the ingredients list.
