What should you compare?
Decide how many portions and flavours you want, then compare the exact bars rather than relying on a claim on the front of the box.
| Priority | What to check | Your needs |
| Flavour and texture |
Count the listed flavours, check their descriptions and see whether the box contents can vary. Grenade says flavours in its selection box may vary. |
I would rather try several flavours than buy a full case of one I might not choose again. |
| Protein per bar |
Compare protein in grams alongside the stated bar weight and serving size. Check the panel for the exact flavour. |
For a portable snack, I want to know what one bar contributes—not just what the pack calls “high protein”. |
| Whole nutrition panel |
Read energy, sugars, fibre, saturates and salt per bar. Check whether the figures change by flavour and whether sweeteners or a polyol warning appear. |
If sugar or the size of a snack matters to me, I need the per-bar figures rather than a front-of-pack phrase. |
| Ingredients and allergens |
Check each flavour’s ingredients, highlighted allergens and precautionary statements. Confirm vegan or gluten-free claims on the precise product. |
I need to know whether every bar in a mixed box fits my dietary restrictions before I use it. |
| Pack size and value |
Compare bar count, weight per bar and like-for-like unit prices. Check any promotion or fulfilment conditions on the listing. |
A smaller pack lets me try a flavour; a larger case only makes sense if I will use the portions. |
Brand and retailer references
These examples show different pack formats and label details to check; a brand name alone does not establish the nutrition or ingredients of every flavour.
Grenade
Grenade UK lists a 12-flavour Protein Bar Selection Box for shoppers considering a mixed case.
- The listed range gives you several flavours to consider in one box.
- Flavours may vary; check individual packaging for allergens and the displayed laxative-effect warning.
Myprotein
The Layered Bar Variety Box combines five flavours with a stated 20g protein per bar.
- A mixed-flavour format suits shoppers comparing flavours before choosing a single case.
- Myprotein says its nutrition figures can vary from the displayed Triple Chocolate figures when you choose another flavour.
PhD
PhD lists flavour-specific nutrition for its Smart Bar 12-pack; the Choc Brownie panel states 21g protein and 1.2g sugars per 64g bar.
- The stated per-bar figures allow a comparison on a defined serving.
- Check the chosen flavour’s panel and the manufacturer’s laxative-effect warning; a 12-pack should not be assumed to be a variety box.
Barebells
Barebells lists a standard mixed Selection Box and a separate Vegan Fudge Brownie bar.
- The standard selection includes four named flavours; the cited Caramel Cashew bar lists 20g protein per 55g bar.
- The Vegan Fudge Brownie bar lists 15g protein per 55g bar, contains wheat and soya, and has precautionary allergen information to check.
Quest
Quest Nutrition describes its OG protein-bar range as dairy-based, with bars containing as much as 21g protein.
- Quest identifies sugar alcohols in the range, giving shoppers a specific ingredient detail to check.
- Confirm the exact flavour’s formulation and listing before including it in a UK weekly shop.
Tesco
Tesco Groceries is a retailer with individual bars and smaller multipacks from different brands, rather than one protein-bar range.
- Its category includes examples of 3-bar and 8-bar packs for shoppers who do not want a 12-bar case.
- Compare nutrition, ingredients, bar weights and listing conditions product by product.

Frequently asked questions
What should I compare on a protein-bar multipack?
Start with the number of bars and flavours, then compare protein, energy, sugars, saturates, fibre and salt per individual bar. Check each flavour’s ingredients too: Myprotein says nutrition can vary by flavour, and Grenade says the contents of its selection box may vary.
Why do some protein bars carry a laxative-effect warning?
UK government food-labelling guidance specifies the warning “Excessive consumption may cause a laxative effect” for foods containing more than 10% polyols. Check the exact bar for sweeteners and warning text, especially if you expect to eat several bars close together.
Does “vegan” or “gluten-free” cover every dietary restriction?
No. The terms address different ingredients: Barebells Vegan Fudge Brownie contains wheat and soya, while Quest describes its gluten-free bars as dairy-based. Read the exact product’s ingredients, highlighted allergens and precautionary statement for the restrictions that matter to you.
Should I check the individual wrappers in a mixed box?
Yes, particularly when allergens or ingredients affect your choice. Flavours can have different formulations, so use each bar’s physical label before eating it rather than treating the outer box description as the label for every bar.
