Choose a late-night protein bar by the exact ingredients and allergen declaration for your required avoidance, then compare the serving size, protein and sugar per bar. Vegan does not mean free from gluten, soya or peanuts, while a gluten-free bar can contain milk; if you eat close to bedtime, consider whether a light portion suits you better than a substantial snack.
Start with a bar described as vegan, then check the exact flavour for soya, gluten-containing ingredients, peanuts and any precautionary allergen statement. Barebells and PhD product information shows why vegan suitability alone cannot answer a separate allergy question.
Look for an explicit gluten-free declaration on the product you intend to buy. Quest describes its protein bars as gluten-free but also identifies dairy-based proteins, including milk protein isolate; check the current pack and local listing for the particular bar.
Think about whether you need a snack and how substantial the portion is. Oxford Health NHS Foundation Trust notes that an empty stomach can be distracting for some people, while a heavy meal soon before bed can interrupt sleep.
Start with the ingredient you need to avoid; only then compare nutrition per bar and whether the portion suits eating late.
| Priority | What to check | Your needs |
|---|---|---|
| Named allergens | Read the ingredients and emphasised allergens on the exact pack. Check any separate ‘may contain’ statement for possible unintended presence; the Food Standards Agency distinguishes this from ingredients deliberately included in a UK prepacked food. | I need to avoid a particular allergen, so a broad front-of-pack description cannot replace the full declaration for this flavour. |
| Dietary description | Check vegan and gluten-free descriptions separately from milk, soya, wheat and peanut declarations. Barebells lists gluten-containing cereals, soya and wheat for Vegan Fudge Brownie; Quest says its gluten-free bars use dairy-based proteins. | A vegan bar might meet my animal-ingredient preference without meeting my allergen requirements. If gluten is my concern, I still need to check whether milk is acceptable. |
| Per-bar information | Compare the stated bar weight, protein and sugar per bar rather than relying on category wording or figures per 100g alone. Check the ingredients if particular sweeteners matter to you. | I want to know what one bar provides and whether that serving, rather than a different-sized bar, is what I intend to eat. |
| Eating late | Consider the portion alongside your usual response to eating near bedtime. Oxford Health NHS Foundation Trust says a light snack can help some people distracted by hunger, whereas a heavy meal soon before bed can interrupt sleep. | If I only want something small before bed, I can choose a portion that fits that intention rather than assuming a protein bar is automatically the right snack. |
Barebells lists gluten-containing cereals, soya and wheat in its Vegan Fudge Brownie bar and warns that it may contain milk, peanuts, tree nuts and sesame. The PhD Smart Plant Vanilla Fudge listing includes soya, gluten-containing malt extract and peanut paste.
Identify the allergen you need to avoid, then read the complete declaration for the exact flavour instead of relying on its vegan description.
Quest describes its protein bars as gluten-free while identifying dairy-based proteins, including milk protein isolate.
If you also avoid milk, check that separate requirement against the specific bar’s current ingredients and allergen information.
A mixed box can contain different recipes. Grenade’s selection-box information warns of milk, soya, wheat and peanuts, as well as traces of gluten, egg, nuts and sesame.
For an allergy-related purchase, check the declaration for every flavour you plan to eat and re-check the physical pack.
A protein bar can be more substantial than the light snack some people want near bedtime. Oxford Health NHS Foundation Trust notes that a heavy meal soon before bed can interrupt sleep.
Check the bar’s serving size and choose whether to have a snack at all based on what suits you.
These examples show why the individual flavour and pack declaration matter more than a brand name or category filter.
PhD describes its Smart Plant protein bars as vegan and advertises 20g plant-based protein and less than 1g sugar, depending on the flavour.
Barebells lists Vegan Fudge Brownie as a 55g bar with 15g protein and no added sugar.
Quest describes its protein bars as gluten-free and says they use dairy-based proteins, including milk protein isolate.
Myprotein’s UK protein-bar range describes vegan and gluten-free options.
Grenade protein bars provide a comparison point for shoppers also considering conventional protein bars.
Tesco Groceries lists protein, vegan and gluten-free snack-bar categories.
These bars and flapjacks offer pack sizes to compare for a late snack. Check the exact flavour’s current ingredients and allergen declaration before choosing one for a free-from requirement.

Compare one 50g flapjack with the portion you want for a late snack. If you need to avoid soya or gluten, check the current ingredients and allergen statement for this flavour before buying.

The pack contains four 40g nut bars. Check the exact bar’s gluten declaration and its peanut, milk, soya and other nut information against the ingredients you need to avoid.

Each listed bar is 50g, so compare its per-bar information with the portion you intend to eat. Check the current milk and soya declarations and any sweetener warning; do not assume this flavour is gluten-free from an ingredients summary alone.

The pack contains three 42g bars. Peanut butter is part of this flavour’s identity; check its full peanut, soya and tree-nut declarations, and confirm any vegan or gluten-free requirement on the current pack rather than assuming either applies.
No: a vegan description does not settle a separate milk-allergy question. Barebells says its Vegan Fudge Brownie bar may contain milk, so check the exact product’s current ingredients and precautionary allergen statement.
No. Quest describes its protein bars as gluten-free but says they use dairy-based proteins, including milk protein isolate. Check the specific bar’s declaration if you also need to avoid milk.
Read its ingredients list and the allergens emphasised within it. The Food Standards Agency says UK prepacked food must carry an ingredients list and emphasise allergens each time they appear; check the physical pack for the bar you will eat.
It flags possible unintended presence of a named allergen rather than saying that allergen was deliberately added. Food Standards Agency-commissioned research describes precautionary allergen labelling in this way, so read it separately from the ingredients list.
That depends on whether you need a snack and how substantial the portion is for you. Oxford Health NHS Foundation Trust notes that a light snack can be useful for some people distracted by an empty stomach, while a heavy meal soon before bed can interrupt sleep.
