For consistent carbohydrate counting, a single-flavour multipack lets you use the same flavour’s per-bar label each time; a mixed box offers more choice for sharing but calls for a check of every flavour. Diabetes UK advises looking at total carbohydrate rather than relying on a low-sugar or ‘diabetic friendly’ claim. Check the portion size, ingredients, allergens and any polyol warning before choosing a box.
For someone managing diabetes, the useful figure is total carbohydrate for the portion eaten, not just sugars on the front of the pack. Diabetes UK says carbohydrate counting is particularly helpful for people using basal and bolus insulin.
A single-flavour case gives everyone the same stated per-bar nutrition; a selection box offers different flavours but may bring different carbohydrate amounts and allergens. Keep each wrapper available when sharing.
Vegan, gluten-free and allergen requirements need checking against the exact bar and flavour. A statement about one product does not establish that every flavour in its range meets the same requirement.
Decide whether consistent per-bar information or flavour variety matters more, then compare the labels of the bars you would actually receive.
Choose this when: You want to refer to the same flavour’s declared portion and nutrition panel for each bar.
Bear in mind: Low sugars alone do not establish the total carbohydrate amount, and a whole case commits you to one flavour.
Choose this when: Several people want different flavours or you would rather not buy a case of one variety.
Bear in mind: Read each included flavour’s nutrition and allergen information; one box is not necessarily one uniform carbohydrate count.
| Priority | What to check | Your needs |
|---|---|---|
| Carbohydrate per bar | Find total carbohydrate for the exact flavour and portion you will eat. Confirm whether one wrapped bar is one stated serving; use per 100g figures when comparing different bar sizes. Diabetes UK advises using the detailed nutrition label rather than front-of-pack information for carbohydrate. | I want a figure I can use for the bar I actually eat, especially if I count carbohydrates. |
| Label claims | Compare total carbohydrate separately from ‘of which sugars’. Check the ingredients rather than treating ‘low sugar’, ‘no added sugar’ or ‘diabetic friendly’ as a judgement about the whole bar. | A low-sugar headline is not enough for my decision; I need to see the full nutrition panel. |
| Flavour consistency | Check which flavours are included and whether each has its own nutrition panel. Myprotein notes that nutrition can vary by flavour in its Layered Protein Bar range. | If I share a mixed box, I want each person to be able to identify the bar and check its own label. |
| Polyols | Look for polyols in the nutrition panel or ingredients and read any excessive-consumption warning. Some listed bars contain substantial declared polyol amounts, even where sugars are low. | Before buying several bars, I want to know whether this flavour uses polyols and carries a warning. |
| Allergens and dietary suitability | Read the ingredient and ‘may contain’ statements for every flavour. Confirm any vegan or gluten-free claim for the exact product, not the brand as a whole. | Different people may share the box, so each bar needs to meet the requirements of the person eating it. |
The figures are different. Barebells lists 16g carbohydrate and 1.3g sugars for a 55g Salty Peanut bar; PhD lists 21g carbohydrate and less than 1g sugars for a 64g Smart Plant bar. Neither sugars figure replaces the total carbohydrate figure.
Compare total carbohydrate for the exact bar and serving first, then read the other nutrition information that matters to you.
Flavours in a selection box can have different nutrition and allergen information. That matters both for repeat carbohydrate counting and for a household sharing the box.
Check the included flavours before buying and keep their individual wrappers available when the box is opened.
Polyols can appear in bars with low sugars. UK government food-labelling guidance requires an excessive-consumption laxative-effect warning when a food contains more than 10% polyols; an on-pack warning is worth reading before buying a case.
Check the exact flavour’s ingredients, declared polyols where shown, and any warning on its wrapper.
Product examples in this category include milk, soya, peanuts, almonds and wheat-containing ingredients. A vegan or gluten-free description for one bar does not cover every product from that brand.
Read each flavour’s ingredient, allergen and ‘may contain’ statements before sharing it.
These ranges illustrate different multipack formats and label checks; the references are not a judgement that every flavour has the same nutrition or dietary suitability.
Grenade offers protein-bar bundles, while Tesco lists its Fan Favourites Selection Box as 10 x 60g bars.
PhD lists Smart Protein Bar and Smart Plant Protein Bar 12-packs; Smart Plant is its plant-based option.
Myprotein offers a Layered Protein Bar twin-pack format for buying more than one box.
UK retailers list Quest Protein Bar 12-packs, including a listing described as gluten-free.
Barebells offers individual protein-bar flavours and a four-flavour 12-pack selection box.
Tesco is a retailer reference for comparing individual bars with multipacks and selection boxes, rather than a protein-bar brand in this list.
These Grenade cases offer one named flavour per 12-bar pack. They are options to consider when you want the same stated bar size throughout a box; check the exact flavour’s nutrition, polyols and allergens before buying for yourself or sharing.

A single-flavour case for sharing when you prefer to check one flavour’s per-bar label. Confirm the total carbohydrate, polyols and allergen declaration for Double Chocolate before using it for carbohydrate counting or offering it to others.

This 12-bar, single-flavour pack offers a Golden Caramel alternative at the same stated bar size as the other Soft Core flavours shown here. Use Golden Caramel’s own carbohydrate and ingredient label; do not transfer figures from another flavour.

The 12 x 50g format keeps this case to one named flavour. Check the Peanut Butter wrapper’s total carbohydrate and polyols, and read its complete allergen and ‘may contain’ statements before sharing.

These bars have a stated 60g size, rather than the 50g size of the Soft Core cases above. Compare carbohydrate on an equivalent basis and check this exact product’s ingredients, allergens, polyols and serving declaration; the low-sugar wording in its name is not a carbohydrate figure.
No: low sugars alone do not tell you the total carbohydrate in a bar. Diabetes UK advises against relying on foods labelled ‘diabetic’ or ‘suitable for diabetics’; check the exact bar’s total carbohydrate and portion size against your own eating plan.
Use total carbohydrate for the portion you will actually eat, rather than the ‘of which sugars’ figure. If you eat one wrapped bar, confirm that the label’s per-bar figure refers to that whole bar; Diabetes UK’s label guidance directs shoppers to the detailed nutrition information for carbohydrate.
A single-flavour box is easier to check against the same declared per-bar panel each time. A mixed box can suit sharing, but read each flavour’s carbohydrate and allergen information separately; Myprotein notes that nutrition can vary by flavour in its Layered Protein Bar range.
It is a warning to read before deciding how to use the bar, not a measure of its sugar content. UK government guidance requires the warning for foods containing more than 10% polyols; check the exact product’s ingredients and wrapper when considering a multipack.
Check each flavour’s ingredient list, allergen declaration and ‘may contain’ statement before offering it to someone else. The included bars may differ, so another flavour’s label or a brand-wide description cannot stand in for the wrapper of the bar being eaten.
