Regular gym-goers with a known favourite
If you already like a particular recipe, a single-flavour case gives you bars to draw from for successive gym-bag trips. PhD lists its Smart Protein Bar in a 12-pack.
Who each pack format suits
People sharing a snack stash
A mixed box gives several people a choice of flavours. Barebells lists four named flavours in its UK 12-pack Selection Box.
Plant-based or allergen-conscious buyers
Check the ingredients for the exact bar and flavour before committing to a case. A vegan description does not establish suitability for every allergy: PhD’s Smart Plant Salted Caramel lists soya and peanut paste.
What to check before choosing
Start with how many bars you will use and whether anyone else will share them, then compare the recipes rather than relying on the front of the pack.
| Priority | What to check | Your needs |
|---|---|---|
| Pack size | Check the bar count and weight per bar. PhD lists a 12-pack Smart Bar; Tesco lists a Grenade 4 × 60g pack. | I want a regular supply if I know the recipe, but would rather try a smaller pack if I do not. |
| Flavour choice | Check whether the pack repeats one flavour or contains several. Barebells’ UK Selection Box lists four flavours across 12 bars. | Several people will share these, so having a choice matters more than stocking one favourite. |
| Nutrition per bar | Compare the stated serving weight, energy, protein and sugars; check the other nutrients relevant to you. PhD lists 21g protein and 250 kcal per 64g Choc Brownie bar, while Myprotein lists 20g protein and 212 kcal per 60g Layered Bar example. | When I put one bar in my bag, I want to know what that whole bar contains, not just a figure for the range. |
| Ingredients | Read the exact flavour’s ingredients and allergen wording, including every flavour in a mixed box. Check polyols and any consumption warning: PhD lists 16g polyols per 64g Smart Plant Salted Caramel bar. | I need to know whether each recipe suits the people who will eat it before buying several at once. |
Buying pitfalls
-
Committing to a case before trying the flavour
A single-flavour case leaves little choice if you dislike the recipe. Ingredients and nutrition can also differ between flavours.
Try a smaller pack or a selection box first if the flavour or texture is unfamiliar, then check the exact product before buying a case.
-
Comparing bars by protein alone
Similar protein figures need not mean similar serving sizes or energy values: PhD lists 21g protein and 250 kcal for its 64g Choc Brownie bar, while Myprotein lists 20g protein and 212 kcal for a 60g Layered Bar example.
Read the nutrition declaration per bar, including energy, sugars and salt, and use per-100g figures when you want a size-adjusted comparison.
-
Assuming a dietary description covers every ingredient
PhD’s vegan Smart Plant Salted Caramel lists soya and peanut paste. Barebells says its vegan Caramel Peanut bar contains wheat protein; its product information also notes lactose in, or possible traces of lactose in, some products.
Check the ingredients, allergens and precautionary wording for each exact flavour, particularly in a mixed box.
-
Overlooking polyols and consumption warnings
PhD lists 16g polyols per Smart Plant Salted Caramel bar. Myprotein’s Layered Bar page warns that excessive consumption may produce laxative effects.
Read the chosen bar’s ingredients and warnings before packing several for the same day.

- The listed formats offer different levels of commitment.
- Check the selected pack’s flavours, ingredients and nutrition rather than assuming the formats contain the same bars.
Tesco

Common questions
Should I buy one flavour or a selection box for gym-bag snacks?
Choose one flavour if you already know you like that bar and want a regular supply; a selection box gives people sharing the pack more choice. Barebells’ UK 12-pack Selection Box lists four flavours, while PhD lists its standard Smart Protein Bar as a single-product 12-pack.
Should I compare protein per bar or per 100g?
Start with per-bar values when one bar is the snack you plan to pack, then use per-100g figures to compare bars of different sizes. Myprotein lists 20g protein and 212 kcal for a 60g Layered Bar example; PhD lists 21g protein and 250 kcal for its 64g Choc Brownie Smart Bar.
What if someone sharing the multipack has an allergy?
Check the ingredients, highlighted allergens and precautionary wording for every exact flavour they might eat. PhD’s Smart Plant Salted Caramel lists soya and peanut paste, while Barebells says its vegan Caramel Peanut bar contains wheat protein; a vegan description alone does not answer an allergy question.
Why check polyols before buying several bars?
Polyol amounts and consumption warnings depend on the recipe. PhD lists 16g polyols per Smart Plant Salted Caramel bar, and Myprotein’s Layered Bar page warns that excessive consumption may produce laxative effects. Check the bar you intend to pack rather than assuming every flavour has the same ingredients.
