For a planned snack around 60–90 minutes before exercise, consider a multipack only after checking that the particular bar provides carbohydrate as well as protein. University College London Hospitals NHS Foundation Trust advises a faster-acting carbohydrate snack instead when exercise starts in about 15–30 minutes. Pack size and flavour matter too: check each bar’s nutrition and allergen label before buying a case to eat regularly or share.
If your next meal is some way off and you plan to eat around 60–90 minutes before exercise, look at carbohydrate and protein per bar—not just the protein figure. University College London Hospitals NHS Foundation Trust describes both as part of a snack for this window.
A multipack provides several portions, but a selection box and a single-flavour case are different commitments. Check the flavours and each bar’s ingredients before choosing one to share.
If listed sugars influence your choice, compare them per bar alongside carbohydrate, ingredients and allergens. A lower sugar figure alone does not establish whether the bar suits the time remaining before training.
Start with when you intend to eat, then compare the exact bars in each pack rather than relying on a claim on the front.
| Priority | What to check | Your needs |
|---|---|---|
| Time before exercise | University College London Hospitals NHS Foundation Trust describes carbohydrate-and-protein snacks for around 60–90 minutes before exercise, and faster-acting carbohydrate snacks for around 15–30 minutes before it. Consider when you last ate a meal. | My session starts in an hour or so, and I want a planned snack rather than something to eat immediately before it. |
| Nutrition per bar | Read carbohydrate and protein together, then check energy and fat for the particular flavour. Myprotein UK lists 20g carbohydrate, 20g protein, 212 kcal and 6.2g fat for its cited 60g Layered Bar. | I want to know what one bar contains, not assume that a protein figure tells me everything about a pre-workout snack. |
| Pack and flavours | Check the bar count, individual size and whether the box mixes flavours. Compare the labels of included flavours rather than assuming their nutrition is identical. | If I have not tried a flavour, a smaller pack or selection box means I need not start with a large single-flavour case. |
| Ingredients and allergens | Read the current ingredient and allergen declarations for every flavour, including precautionary statements. Check sweeteners and any consumption warning on the exact bar. | Before sharing a box, I need to know whether each person can eat the bars it contains. |
A lower-sugar protein bar may not serve the same purpose as the faster-acting carbohydrate snack University College London Hospitals NHS Foundation Trust describes for roughly 15–30 minutes before exercise.
Decide when you will eat before buying a case. Consider a carbohydrate-and-protein bar for the earlier, 60–90-minute window; for the shorter window, follow the guidance appropriate to your circumstances rather than assuming the bar is interchangeable.
Bars with a protein figure on the front can differ in their carbohydrate, energy and fat per serving. Myprotein UK’s cited 60g Layered Bar, for example, lists 20g carbohydrate and 20g protein, alongside 212 kcal and 6.2g fat.
Compare the per-bar panel for the exact flavour against the time before your session and your usual meal pattern.
Tesco Groceries lists milk, soya and wheat in the Grenade Fan Favourites Selection Box and gives additional precautionary allergen information. A mixed box should not be treated as though every flavour has the same ingredients.
Check the current label of each included bar before anyone eats it, particularly where allergens affect the people sharing the box.
A single-flavour case leaves less room to change your choice if the flavour or ingredients do not suit you. Some cited PhD and Myprotein bars also carry warnings about excessive consumption and laxative effects.
Consider a smaller pack or a selection box first, and read the consumption advice on the bars you choose.
These examples show different pack formats and label details to compare; a brand name alone does not establish that every flavour has the same nutrition or ingredients.
Tesco Groceries lists a Grenade Fan Favourites Selection Box containing 10 x 60g bars.
Tesco Groceries lists individual 64g Smart Protein Bars in Chocolate Peanut Butter and Chocolate Brownie flavours.
Myprotein UK lists both a Layered Bar and a Layered Bar Variety Box.
Barebells lists a Selection Box in its UK shop.
Quest Nutrition’s cited Chocolate Brownie information describes a US-market bar, not a confirmed UK multipack formulation.
These multipacks offer different bar counts and flavours to consider for planned snacks. Check carbohydrate, protein and ingredients on the exact bars before deciding which pack suits your training schedule or the people sharing it.

Four 60g bars make this a smaller pack to consider when trying the Oreo flavour. For pre-workout use, check carbohydrate and protein per bar and read the current allergen label.

This 12-bar, single-flavour case is a different commitment from the four-bar Oreo pack. Check the exact bar’s carbohydrate, protein, ingredients and allergens before choosing it for regular snacks.

Each bar in this 12-pack is labelled as 50g, rather than the 60g size of the Oreo packs above. Compare nutrition per bar when choosing a pre-workout snack, and check the Double Chocolate ingredients before sharing.

This pack contains 18 bars of 42g each. Before using them as a planned pre-workout snack, compare carbohydrate and protein per bar with your timing needs, and check the nut and other allergen declarations.
It is not the default snack described for a workout starting in about 15–30 minutes: University College London Hospitals NHS Foundation Trust advises faster-acting carbohydrate for that window. Its guidance places a snack containing carbohydrate and protein around 60–90 minutes before exercise when a meal was not eaten in the preceding two to three hours.
Start with carbohydrate and protein per bar, then check energy, fat, ingredients, allergens, sweeteners, bar count and flavours. Read the panel for the particular flavour you will eat; a high-protein claim on its own does not tell you whether the bar matches your pre-workout timing.
Yes. Check the current label on the exact bar before eating it, especially its ingredients and allergen declaration. This matters for selection boxes, where flavours need not have identical recipes.
Yes. Tesco Groceries lists milk, soya and wheat for the cited Grenade Fan Favourites Selection Box, along with precautionary allergen information. Do not use its label as a substitute for the declaration on a different pack or flavour.
