People taking a break from work
A bar is easy to carry for an afternoon break. Compare its full nutrition panel if you want a treat-style snack rather than assuming that every protein bar has the same ingredients or serving size.
Who these bars may suit
Adults looking for a substantial protein serving
If protein per snack is the deciding factor, compare grams per complete bar. The cited manufacturer pages include bars listing 20g to 23g per serving, but those figures apply to specific products and flavours.
Plant-based or allergen-aware shoppers
Vegan suitability and allergen suitability are different checks. Read the exact flavour’s ingredients and allergen statements, including any warnings about possible cross-contact.
What to compare before buying
Start with the serving you would actually eat, then compare the ingredients and nutrition details that matter to your afternoon break.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per bar | Read the grams of protein and the serving size for one complete bar. Compare like-for-like servings rather than a front-of-pack claim alone. | I want to know how much protein I would get from the bar I actually eat, not just from a per-100g figure. |
| Flavour and format | Check the exact flavour and whether it is layered, soft or another format. A flavour choice does not establish its nutrition values. | For an afternoon tea break, I’d choose a flavour I want to eat while still checking the panel on that version. |
| Sugars and sweeteners | Read “of which sugars” per bar, then check the ingredients, polyols and any excessive-consumption warning. A low sugar figure does not describe the sweeteners used. | I’m comparing sugars without overlooking ingredients or warnings that could affect my choice. |
| Fibre and energy | Compare fibre and kcal for the same serving size. Myprotein lists 6.6g fibre and 212 kcal for its 60g Triple Chocolate Fudge Layered Bar; those figures should not be applied to every flavour. | If fibre or the size of an afternoon snack matters to me, I want the figures for the particular bar I’m buying. |
| Dietary suitability | Check the exact pack’s ingredients, allergen declaration and any “may contain” statement. Do not use a vegan claim as an allergen check. | I need the bar and flavour to match my dietary requirements, not just a protein target. |
| Pack and routine | Check the number of bars, individual bar weight and storage instructions before choosing a multipack. | A single portable bar could suit a busy afternoon; a multipack only makes sense if I know I want that particular flavour and formulation. |
Common buying mistakes
-
Choosing only by the largest protein figure
A protein total does not tell you the serving size, sugars, fibre, energy or ingredients. The cited Grenade, PhD, Myprotein and Barebells products list different amounts per bar.
Compare the complete per-bar panel for the exact flavour before deciding whether its protein amount meets your snack preference.
-
Reading “low sugar” as “no sweetener considerations”
Several cited product pages include polyols or excessive-consumption laxative-effect warnings. PhD lists 16g polyols for its cited 64g Smart Plant bar.
Read the ingredients and warning text, particularly before committing to a multipack of an unfamiliar bar.
-
Assuming a vegan bar meets every dietary restriction
Vegan suitability does not rule out soy, peanuts or gluten-containing ingredients. The cited PhD Smart Plant product information identifies ingredients that require separate allergen checks.
Check the ingredient list and allergen statements for the precise product and flavour you intend to buy.
-
Treating an afternoon bar as an automatic meal replacement
A bar can be convenient between meals, but its protein figure alone does not establish that it replaces the variety of food in a meal.
Choose it as a snack when portability is useful, and consider it alongside the rest of what you eat.
Brand ranges to compare
These manufacturer examples show why figures and dietary statements need to be checked by product and flavour; they do not describe every bar a brand makes.
Grenade
Grenade’s cited 60g dessert-flavoured bars include White Chocolate Cookie and Cookie Dough.
- Grenade lists 23g protein and 1.7g sugars for White Chocolate Cookie, and 21g protein and 1.4g sugars for Cookie Dough.
- Check milk and soy ingredients, flavour-specific allergen statements and the manufacturer’s excessive-consumption warning. The cited products are labelled unsuitable for children under 14.
PhD
PhD has standard Smart Bar and plant-based Smart Plant products; their panels should not be treated as interchangeable.
- PhD lists 21g protein, 238 calories and 1g sugar for its cited Smart Bar presentation. Its cited 64g Smart Plant flavour lists 21g protein and 0.6g sugars.
- The cited Smart Plant panel lists 16g polyols per bar. Check the exact flavour’s ingredients for soy, peanuts and other allergens.
Myprotein
Myprotein’s Layered Protein Bar is a portable, layered-format option.
- Myprotein lists 20g protein, 6.6g fibre, 1.9g sugars and 212 kcal per 60g Triple Chocolate Fudge bar.
- The brand says nutrition varies by flavour. The cited version is not suitable for vegetarians and carries an excessive-consumption laxative-effect warning.
Barebells
Barebells offers original, soft and vegan bar formats, with suitability varying by product.
- Barebells lists 20g protein, 1.4g sugars and 190 kcal per 55g Cookies & Cream bar.
- That bar contains milk and has a “may contain” statement for several other allergens. It also carries an excessive-consumption laxative-effect warning; check each variant’s label.
Quest
Quest describes its original protein-bar range as containing up to 21g protein per bar.
- Quest describes its protein bars as gluten-free.
- The brand says its bars contain sugar alcohols and that tolerance varies. Check the label on the particular bar when shopping in the UK.

Questions about afternoon protein bars
How do I compare protein amounts between bars?
Use grams of protein per complete bar and note its weight. The cited Grenade, PhD, Myprotein and Barebells product pages include specific bars listing 20g to 23g protein, but that range does not describe every flavour or every bar on this page.
Can a protein bar replace a meal?
Do not assume that a protein bar replaces a meal simply because it lists a substantial protein amount. It can be a portable afternoon snack; Myprotein describes its cited bar as intended alongside a varied, balanced diet.
Why check sweeteners when sugars are low?
The sugars figure does not show which sweeteners or polyols a bar contains. PhD lists 16g polyols for its cited Smart Plant bar, and several cited manufacturers include excessive-consumption laxative-effect warnings. Read the ingredients and warnings for the exact flavour.
Are vegan protein bars free from allergens?
No. PhD describes Smart Plant as suitable for vegans and vegetarians, while its cited product information includes soy and peanut ingredients. Check the particular bar’s full ingredient and allergen statements rather than relying on its vegan description.
What should I check before buying a different flavour?
Read the nutrition panel, ingredients and allergen statements for that flavour. Myprotein says nutrition can vary across Layered Bar flavours, and a dietary or allergen statement for one product should not be carried over to another.
