Buyers replacing some office biscuits with protein bars
If you are stocking desks or a meeting room, compare the stated protein per bar rather than assuming every snack labelled ‘protein’ provides the amount you have in mind.
Who is the tin for?
Colleagues looking for a vegan option
A vegan-labelled bar can widen the choice, but keep its ingredients accessible. PhD’s Smart Plant formulation includes soya and peanut paste.
People checking ingredients or sweeteners
In a communal tin, the exact flavour and its wrapper matter. Allergen statements and polyol information can differ between products, so an unlabelled bar is difficult to assess.
What should you check?
Start with the amount in one bar, then check whether its ingredients and packaging work for everyone who may use the tin.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per bar | Read grams of protein per serving and the bar weight. Check the selected flavour’s panel, not just a range-level headline. | I want to know what one desk snack provides, rather than rely on the word ‘protein’ on the front of the pack. |
| Full nutrition panel | Compare sugars, energy, saturates and fibre per bar alongside protein. Use per 100g figures when comparing bars of different sizes. | A protein claim alone does not tell me how the whole bar compares with another snack. |
| Ingredients and allergens | Check the exact flavour’s ingredients, allergen statement and any ‘may contain’ wording. Keep the original wrapper available. | Others may use the tin, so I need them to be able to identify a bar before taking it. |
| Polyols and sweeteners | Read the ingredients, any stated polyols per bar and product warnings. Do not use the sugar figure as a substitute for those checks. | If I am choosing a lower-sugar bar, I still want to know which sweeteners it contains. |
| Pack and portion size | Confirm the number of bars and weight of each bar. Keep different flavours identifiable if you put several types in one tin. | A multipack needs to suit how many people will use the tin without losing the information on each bar. |
Common buying mistakes
-
Treating ‘protein’ as the whole nutrition story
Action on Sugar’s 2025 analysis of supermarket snack bars illustrates why a front-of-pack claim should not stand in for the complete nutrition panel; its market findings do not describe every individual bar.
Compare protein, sugars, energy, saturates and fibre for the flavour and serving size you intend to buy.
-
Putting a bulk box into the tin without checking ingredients
Grenade’s Peanut Nutter contains peanuts, milk and soya and carries additional ‘may contain’ statements. PhD’s vegan Smart Plant formulation still includes soya and peanut paste.
Check each chosen wrapper before stocking the tin, and keep bars and their ingredient information identifiable.
-
Assuming lower sugar means fewer ingredient checks
Grenade’s Peanut Nutter carries an excessive-consumption laxative-effect warning, while PhD lists 16g polyols per 64g Smart Plant bar.
Read the polyol information and warnings for the exact product rather than judging it by sugars alone.
-
Overlooking the number and size of bars
A 12 × 60g box and a pack of smaller bars provide different portions and numbers of snacks.
Check the pack count and grams per bar before deciding how many packs an office tin needs.
Brand and retailer references
These examples show why the exact product and flavour matter; a brand name alone does not establish the nutrition or ingredients of every bar it sells.
Grenade
Grenade offers Carb Killa and Soft Core protein-bar lines.
- Grenade states that Peanut Nutter provides 20g protein and 1.7g sugars per bar.
- That Peanut Nutter product contains peanuts, milk and soya, has further ‘may contain’ statements and carries a polyol warning. Check other Grenade flavours separately.
PhD
PhD offers conventional Smart Bar and vegan Smart Plant formats.
- PhD’s checked Smart Plant panel lists 21g protein per 64g bar and describes the product as suitable for vegans.
- The Smart Plant formulation includes soya and peanut paste. PhD’s Smart Bar range page gives differing protein headlines, so check the chosen flavour’s pack.
Myprotein
Myprotein’s Layered Protein Bar is a confectionery-style option.
- Its Triple Chocolate Fudge panel lists 20g protein, 1.9g sugars and 6.6g fibre per 60g bar.
- Myprotein says nutrition varies slightly by flavour, states that the product is not suitable for vegetarians and warns about excessive consumption.
Barebells
Tesco lists a Barebells Soft Protein Bar Cinnamon Bun in a 55g size.
- Check that variant’s own nutrition panel and ingredients before treating it as a match for the tin’s protein or dietary requirements.
Tesco
Tesco is a retailer comparison point, not a single protein-bar manufacturer.
- Its protein-bar category lists several snack formats, including soft bars, nut-based bars and flapjacks.
- Compare individual products rather than assuming a shared category means matching protein amounts, ingredients or bar sizes.
Grenade bars to consider
These Grenade multipacks cover Oreo and three Soft Core flavours for a sweet-snack office tin. Check the nutrition and ingredient label of the exact pack you choose, and keep that information with the bars when sharing them.

Grenade Soft Core Double Chocolate, 12 × 50g
A 12-bar Double Chocolate pack for a tin used by several colleagues. Check the stated protein for each 50g bar and retain its ingredient information, particularly for anyone checking milk, soya or sweeteners.
No image available
Grenade Soft Core Golden Caramel, 12 × 50g
A Golden Caramel option in the same 12 × 50g pack format. Compare its own nutrition panel with the other flavours, and check ingredients and polyols before adding it to a shared tin.
No image available
Grenade Soft Core Peanut Butter, 12 × 50g
A Peanut Butter flavour in a 12-bar pack. Check its exact peanut and other allergen statements before considering it for colleagues, and keep the product identifiable rather than placing unlabelled bars in the tin.
Questions about a shared tin
Can I put protein bars into the tin without their wrappers?
Keep each bar’s original wrapper or its exact flavour-specific ingredient and allergen information accessible. Grenade’s Peanut Nutter contains peanuts, milk and soya and has additional ‘may contain’ statements; PhD’s vegan Smart Plant formulation includes soya and peanut paste.
Does a lower-sugar bar need any other ingredient checks?
Yes. Grenade’s Peanut Nutter warns that excessive consumption may have a laxative effect, and PhD lists 16g polyols per 64g Smart Plant bar. Read the ingredients and product warning for the flavour you choose.
Is there a vegan protein bar to consider?
PhD describes its Smart Plant bar as suitable for vegans, and its checked panel lists 21g protein per 64g bar. It still needs an allergen check because the formulation includes soya and peanut paste.
Are all bars in a protein-bar category comparable?
No. Tesco’s category includes soft bars, nut-based bars, flapjacks and different pack formats. Compare protein and the rest of the nutrition panel for the individual serving, then check ingredients and bar size before stocking an office tin.
