For a lighter, individually wrapped party snack, start by comparing calories per whole bar: Tesco lists the 35g Grenade Salted Caramel bar at 129 kcal and 12g protein. The named 55–64g bars from Barebells, Myprotein, Grenade and PhD provide 16–21g protein in the cited examples, but also contain 205–250 kcal per bar. Choose the portion and protein amount that suit the snack you intend to offer, then check each flavour’s current ingredients and allergen label.
If guests will also have other party food, compare the calories in a complete wrapper rather than relying on the per-100g figure. Tesco lists a 35g Grenade Salted Caramel bar at 129 kcal; the named standard-size examples from Barebells, Myprotein, Grenade and PhD start at 205 kcal.
A larger bar may make sense when protein content matters more than keeping the portion small. The cited 55–64g examples from Barebells, Myprotein, Grenade and PhD list 16–21g protein per bar, alongside their different calorie amounts.
Choose by the exact flavour and current wrapper, not the protein-bar category. The reviewed Grenade and Barebells products identify milk and soy, while PhD describes Smart Plant as suitable for vegans and Quest describes its protein bars as gluten-free. Those descriptions do not replace an ingredient and allergen check for each guest.
Decide whether the bar is a small addition to the party spread or a more substantial protein-led snack, then compare complete servings and labels.
| Priority | What to check | Your needs |
|---|---|---|
| Whole-bar portion | Compare kcal per wrapper and bar weight, not just values per 100g. Tesco lists 129 kcal for a 35g Grenade Salted Caramel bar; Barebells lists 205 kcal for its 55g Banana Dream bar. | I’m putting out several party snacks and want to know what one complete bar adds to the spread. |
| Protein amount | Read protein grams alongside kcal for the same serving. Myprotein lists 20g protein and 212 kcal per 60g Layered bar; Tesco lists 21g and 222 kcal for the 60g Grenade Chocolate Chip Salted Caramel bar. | Some guests may prefer a bar chosen for its protein content, even if it is a larger snack. |
| Sugars and polyols | Check kcal, sugars and polyols separately. Tesco lists 11g polyols in the cited 35g Grenade bar and 18g in its cited 60g bar; several named manufacturers warn about laxative effects from excessive consumption. | I want guests to be able to see the sweetener information before taking a bar, particularly if they might have more than one. |
| Dietary suitability | Read the exact flavour’s ingredients, allergen declarations and precautionary statements. A vegan or gluten-free description does not answer every allergen question; check the current UK pack. | If a guest has an allergy or dietary exclusion, I need a clearly labelled option I can assess with them rather than assuming any protein bar will do. |
Different wrapper sizes change the serving comparison. Tesco lists 129 kcal for the 35g Grenade Salted Caramel bar, while Myprotein lists 212 kcal for a 60g Layered bar and PhD lists 245 kcal for its 64g Choc Peanut Butter Smart Bar.
Set a portion preference using kcal per complete bar, then compare protein for those same servings.
Sugars and energy are separate label values. Tesco’s cited 60g Grenade bar lists 222 kcal and 18g polyols; Myprotein, Barebells and PhD also give excessive-consumption cautions for the cited bars.
Check kcal, sugars and polyols on the exact flavour rather than using one front-of-pack description as a substitute for the nutrition panel.
Individual wrapping does not resolve an ingredient or allergen concern. The reviewed Grenade and Barebells labels identify milk and soy, and precautionary statements differ between products.
Keep the wrappers available and check the current ingredients and allergen statements with guests who need to avoid particular foods.
The cited 60–64g Myprotein, Grenade and PhD bars provide 20–21g protein and 212–250 kcal per bar. That is a different portion decision from Tesco’s cited 35g Grenade bar at 129 kcal and 12g protein.
Offer a smaller-bar choice when portion size leads the decision, and treat a standard bar as a separate protein-led option.
These references concern named bars and product lines, not every flavour a brand makes or the Joybuy products below.
The Tesco listings for Grenade’s 35g Salted Caramel bar and 60g Chocolate Chip Salted Caramel Carb Killa bar show why wrapper size matters.
The cited 60g Triple Chocolate Fudge Layered Protein Bar is a standard-size comparison point.
The cited 55g Banana Dream bar offers another portion size to compare with 35g and 60g bars.
PhD’s standard Smart Bar and separately labelled Smart Plant line address different protein-bar choices.
Quest describes its protein-bar range as gluten-free, making the current UK pack worth checking for guests seeking that label.
Tesco is a UK retailer whose named product listings provide per-bar figures for comparing particular Grenade products.
These Joybuy listings cover Grenade Soft Core bars, a Nature Valley multipack and a Grenade Oreo Flavour multipack. For a Christmas-party choice, compare each listed wrapper size and pack format with the current nutrition and allergen information for that exact product.

The 50g bar size gives party guests a different portion to compare with a 35g mini bar or a 60g standard bar.
Pack: 12 x 50g. Check the Double Chocolate wrapper for per-bar kcal, protein, polyols and allergens before serving.
Image unavailable
If Golden Caramel suits the planned selection of flavours, compare its complete 50g bar with the other party-snack portions.
Pack: 12 x 50g. Use this flavour’s own wrapper to check kcal, protein, polyols and allergens.

For a shared party table, check this Peanut Butter flavour against guests’ allergen needs before including it.
Pack: 12 x 50g. Compare kcal and protein per complete bar, and read the current ingredient and allergen statements.

The 40g bar is a smaller physical portion than the 50g and 60g listings here; weight alone does not establish its calorie content.
Pack: 4 x 40g. Check kcal and protein per bar, plus the current allergen and sweetener information.
Image unavailable
This 60g format is worth comparing if the party selection includes a larger bar as well as smaller portions.
Pack: 4 x 60g. Check the Oreo Flavour label for per-bar kcal, protein, polyols and allergens; figures for other Grenade flavours do not establish this one’s values.
Use kcal per complete wrapper for the portion a guest would take. Tesco lists 129 kcal for its cited 35g Grenade Salted Caramel bar, while the named 55–64g examples from Barebells, Myprotein, Grenade and PhD list 205–250 kcal; compare their protein amounts alongside those serving sizes.
Not necessarily: sugars and kcal are different nutrition-panel values. For example, Tesco lists 222 kcal per 60g Grenade Chocolate Chip Salted Caramel bar, so check energy per whole bar even when a low-sugar description catches your eye.
Check each exact wrapper’s ingredients, allergen declaration and precautionary statements with the guest concerned. The reviewed Grenade and Barebells products identify milk and soy, but the relevant warnings depend on the particular product and flavour.
No; look for the relevant statement on the particular product. PhD describes Smart Plant as suitable for vegans and vegetarians, and Quest describes its protein bars as gluten-free, but check the current UK pack and its full ingredient and allergen information before serving.
The amount can differ by bar, and some cited manufacturers warn that excessive consumption may cause laxative effects. Tesco lists 11g polyols in the cited 35g Grenade bar and 18g in its cited 60g bar; read the exact wrapper if guests may take more than one.
