People stocking a shared biscuit tin
Individually wrapped bars can sit alongside other office snacks. Compare the whole-bar serving size and kcal, and leave the packaging available so colleagues can check ingredients before taking one.
Who is choosing for the office?
Desk workers comparing portions
If you are choosing one bar as an afternoon snack, the per-bar kcal and protein figures are more directly useful than a per-100 g figure alone. Check that the stated serving matches the amount you intend to eat.
Buyers accounting for colleagues’ allergies
Ingredients and precautionary allergen statements can differ by flavour. Keep each bar in its original wrapper and check the exact product before adding it to a communal tin.
What matters when choosing a bar?
Start with the portion in the wrapper, then compare its protein, sugar and ingredients against what matters to the people using the tin.
| Priority | What to check | Your needs |
|---|---|---|
| Calories per bar | Read the kcal figure for the whole bar and its weight. The NHS notes that labels may show values per 100 g or per portion, and that the stated portion may differ from the amount eaten. | I want to compare the snack I will actually take from the tin, not just a figure calculated for 100 g. |
| Protein and flavour | Compare protein for the exact flavour and bar size. Barebells UK states 20 g per 55 g Cookies & Cream bar; PhD states 21 g per 64 g Choc Peanut Butter bar. Glanbia Nutritionals identifies taste and protein as important attributes among the UK and Irish bar consumers it discusses. | A sweet snack needs to be one I will choose, while the protein amount should match what I am looking for from a bar. |
| Sugar and sweeteners | Read sugar per bar alongside kcal and the ingredients. Check the pack for polyols and any excessive-consumption warning; a lower sugar figure does not establish a lower kcal figure. | If I favour a lower-sugar flavour, I still want to know what is in the whole bar and what its packaging says about consumption. |
| Allergens | Check the ingredients and precautionary allergen statement on each exact flavour. The cited Barebells Cookies & Cream and Grenade Chocolate Chip Salted Caramel products list milk and possible traces of other allergens. | Colleagues need to be able to identify the bar and read its own wrapper before choosing one. |
| Replenishment | Check the bar count and flavour in a multipack, and whether each bar remains individually labelled. | I want a pack that is straightforward to restock without losing the ingredient information people need at the tin. |
What is easy to overlook?
-
Assuming more protein means fewer calories
The named bars do not follow a single protein-to-kcal pattern. Barebells UK lists Cookies & Cream at 190 kcal and 20 g protein per 55 g bar, while PhD lists Choc Peanut Butter at 245 kcal and 21 g protein per 64 g bar.
Compare kcal, protein and bar weight for the exact flavours you are considering; do not use a front-of-pack protein claim as a calorie comparison.

Putting unwrapped bars in a communal tin
Removing wrappers makes it harder to connect a bar with its ingredients and allergen statement, particularly when several flavours look similar.
Keep the original wrappers on and make the multipack’s ingredient information available alongside the tin.
-
Looking at sugar without reading the warning
The cited Barebells Cookies & Cream and Grenade Chocolate Chip Salted Caramel products carry warnings about laxative effects from excessive consumption.
Check the warning on the exact pack and keep it visible to anyone taking a bar.
Which brands offer useful reference points?
These examples show why flavour, portion size and ingredients matter more than a brand-wide assumption.
Barebells
Barebells UK lists its Cookies & Cream bar at 190 kcal and 20 g protein per 55 g bar.
- The stated per-bar figures provide a clear portion comparison.
- This flavour contains milk, may contain cereals containing gluten, soy, peanuts and nuts, and carries an excessive-consumption warning.
PhD
PhD lists its full-size Smart Bar Choc Peanut Butter at 245 kcal and 21 g protein per 64 g bar.
- The named bar offers a 64 g portion with a stated 21 g of protein.
- Check the kcal and warnings for the exact flavour and size rather than applying these figures across the range.
Myprotein
Myprotein lists its Soft Protein Bar Double Dark Chocolate at 244 kcal and 16 g protein per bar.
- The named flavour provides a specific whole-bar comparison for a chocolate-style snack.
- Other flavours have different kcal figures; check each variant’s ingredients and allergen information.
Grenade
Grenade states that its Chocolate Chip Salted Caramel bar contains 20 g protein and 1.4 g sugar.
- Its stated protein and sugar figures can be compared with those on other exact flavours.
- Check the pack’s kcal, allergens and polyol warning before choosing it for a shared tin.
Quest
Quest describes its OG Protein Bars as containing up to 21 g protein per bar.
- The stated protein figure gives shoppers a feature to check against an exact pack.
- Confirm the flavour’s kcal and ingredients on the pack offered by the seller before comparing it with the named UK examples.
Tesco
Tesco is a retailer offering a range of protein-bar brands rather than a single protein-bar manufacturer.
- A supermarket range lets an office buyer compare flavours and pack formats in one place.
- Check the exact product and seller when choosing a bar; a retailer’s range does not make different flavours nutritionally interchangeable.

Grenade Soft Core Double Chocolate, 12 × 50 g
A chocolate-flavoured multipack for stocking the tin. Keep the individual wrappers available and check the pack’s per-bar nutrition, milk and soya information, and sweetener warning before sharing.
No image available
Grenade Soft Core Golden Caramel, 12 × 50 g
A caramel-flavoured option in the same pack format. Compare its own per-bar nutrition rather than carrying figures over from Double Chocolate, and check the wrapper’s milk, soya and sweetener information.
No image available
Grenade Soft Core Peanut Butter, 12 × 50 g
This peanut-butter flavour calls for particular care in a shared tin: check its peanut, milk and soya information on the wrapper before offering it to colleagues. Compare its own per-bar kcal with the other flavours.
No image available
PhD Smart Salted Caramel, 12 × 64 g
At 64 g per bar, this is a different portion size from the 50 g Grenade Soft Core packs above. Read its own kcal and protein figures, and retain the wrapper for its allergen information and excessive-consumption warning.
No image available
PhD Smart Chocolate Peanut Butter, 12 × 64 g
For this flavour, PhD states 245 kcal and 21 g protein per 64 g bar. The product information also identifies milk and soya, possible traces of gluten and eggs, and an excessive-consumption warning; keep those details with the wrapped bars.
Common questions
Should I compare kcal per 100 g or per bar?
Start with kcal for the amount you expect to eat: for one individually wrapped bar, that is usually the whole-bar figure. The NHS notes that labels may also show values per 100 g and that a manufacturer’s stated portion may differ from your own.
What should I check before putting bars in a shared tin?
Check each exact flavour’s ingredients, allergens and warnings, and leave its original wrapper on. The cited Barebells Cookies & Cream and Grenade Chocolate Chip Salted Caramel bars identify milk and possible traces of other allergens, so their front-of-pack protein figures are not enough for a colleague to choose safely.
Why do some bars carry a laxative-effect warning?
The cited Barebells Cookies & Cream and Grenade Chocolate Chip Salted Caramel products contain sweeteners or polyols and warn that excessive consumption may have laxative effects. Check the wording on the exact bar rather than assuming every flavour carries the same warning.
Does a protein bar replace lunch?
A protein figure alone does not establish that a bar replaces lunch. Joybuy’s product information for Barebells Cookies & Cream says not to use it as a substitute for a varied, balanced diet.
