Choose a selection box if you are still trying flavours and textures; choose a fixed-flavour multipack once you know you will use that particular bar regularly. For an office packed lunch, check the nutrition information, ingredients, allergens and any warnings on the individual bar rather than treating a protein claim as a verdict on the whole lunch.
If you are filling a desk drawer for the first time, a selection box lets you try different bars before committing to one flavour. Grenade and Myprotein both say the contents of their selection boxes can vary, so check what you will receive.
If you already know the flavour and texture you want, a fixed-flavour multipack makes it simpler to pack the same bar repeatedly. Check the nutrition information for that exact flavour and bar size; PhD’s published Choc Brownie figures, for example, should not be applied to every Smart Bar.
A selection box needs a flavour-by-flavour check. Read each wrapper’s ingredients, allergen information and any warning about excessive consumption before adding a bar to a packed lunch or shared snack drawer.
Decide how much flavour variety you want, then compare the individual bars you might actually take to work.
| Priority | What to check | Your needs |
|---|---|---|
| Pack format | Check whether the pack contains only bars or a mix of snacks, how many items it contains, and whether flavours can change. Grenade describes a 12-bar selection box; Myprotein describes a seven-item snack box whose products may vary. | I want to try different flavours before filling a desk drawer with one bar. If I already have a favourite, a fixed-flavour pack may make more sense. |
| Protein and serving size | Read protein and energy per bar, alongside the bar’s weight. Use the figures for the exact flavour and size, rather than another bar in the same range. | I want to know what one bar contributes to the lunch I am packing, not judge it by the claim on the front of the box. |
| Full nutrition label | Compare sugars, saturated fat and salt per bar. When bar sizes differ, compare the per-100g figures too; NHS food-label guidance explains how these values appear on prepacked foods. | Two bars may come in different sizes, so I want to compare both the portion I would eat and equivalent amounts. |
| Ingredients and warnings | Read the current ingredients and allergen information for each flavour, including precautionary statements. Check any product-specific warning about excessive consumption. | In a mixed box, I cannot assume every wrapper has the same ingredients or warnings. |
| Shopping routine | Check whether you can buy an individual bar to try before choosing a multipack. Tesco’s protein-bar category includes both individual bars and multipacks, though the selection can change. | I would rather try one bar during a grocery shop than commit to a full box of an unfamiliar flavour. |
A protein figure does not describe the rest of the bar. PhD lists 21 g protein, 250 kcal and 3.4 g saturated fat for its 64 g Choc Brownie Smart Bar; those figures apply to that stated flavour and size.
Read the whole per-bar panel and consider the bar alongside the other food in your packed lunch. Use per-100g values when comparing different-sized bars.
Grenade says flavours in its selection box can vary and lists several allergens and possible traces. A suitable-looking outer box is not a substitute for checking the particular bar you intend to pack.
Check the current box information and every relevant wrapper before choosing a flavour, particularly where ingredients or allergens determine what you can eat.
Grenade’s selection-box page and PhD’s Smart Bar page warn that excessive consumption may have a laxative effect. Whether a warning applies must be checked on the exact product.
Read the wrapper before putting several bars in a desk drawer; do not assume all low-sugar bars carry identical ingredients or warnings.
Grenade offers a 12-bar selection box for trying different flavours before choosing a repeated-flavour pack.
PhD’s Smart Bar 12-packs are a fixed-flavour option for shoppers who have settled on a particular bar.
Myprotein describes its Protein Snack Box as seven bars and snacks, rather than a bar-only multipack.
Barebells has original, soft and vegan bar lines, making the exact product line and flavour important when comparing bars.
Quest describes several characteristics of its protein-bar range on its global website.
Tesco is a grocery-shopping route for comparing individual protein bars and multipacks, not a single bar manufacturer.
These are fixed-flavour protein-bar multipacks for adding a familiar bar to an office lunch: four contain 12 bars, while the Oreo-flavour pack contains four. Check the exact flavour and wrapper before choosing a pack to repeat.

This fixed-flavour pack suits a repeat lunch routine if you already know you want the Salted Caramel bar.
It contains 12 x 64g bars. Check this flavour’s own nutrition information, ingredients and any wrapper warning rather than using figures for another PhD flavour.

Choose a single-flavour box like this after deciding that Double Chocolate is a flavour you want to pack regularly.
The pack is listed as 12 x 50g bars. Read the current wrapper for the exact bar’s nutrition, allergens and any warning.

This fixed-flavour pack is a more considered choice once you know Golden Caramel suits your lunch routine.
It is listed as 12 x 50g bars. Compare its individual-bar label with any alternatives you are considering, including ingredients and warnings.

A 12-bar Peanut Butter pack is for someone ready to repeat that flavour, rather than sample a variety.
The listed size is 12 x 50g. Check the exact wrapper’s peanut and other allergen information, nutrition panel and warnings before packing a bar.

The four-bar format involves fewer bars of one flavour than a 12-pack, which may matter if you are not ready to stock a desk drawer.
It is listed as 4 x 60g bars. Check the current individual-bar label for nutrition, ingredients, allergens and warnings.
Choose a variety box to try flavours and textures; choose a fixed-flavour multipack when you already know you want to repeat that bar. Grenade and Myprotein say their selection-box contents can vary, so check the actual assortment and individual wrappers.
Do not assume that a protein bar is a complete lunch. PhD describes its Smart Bar as a snack, preferably eaten between meals; assess the particular bar alongside the other food you plan to pack.
Compare the portion you would eat: energy, protein, sugars, saturated fat and salt per bar, then use per-100g values if the bars differ in size. NHS food-label guidance identifies these nutrition-label figures; a claim on the front does not replace the full panel.
Check the current information for every flavour you might eat, including each wrapper’s ingredients, emphasised allergens and precautionary statements. Grenade says its selection-box flavours can vary and lists several allergens and possible traces, so a brand-level assumption is not enough.
It is a product-specific warning about excessive consumption. Grenade’s selection-box page, PhD’s Smart Bar page and Tesco’s Barebells Pistachio Spread listing carry such warnings; read the exact wrapper rather than assuming every protein bar has the same wording.
