Hosts buying for adults who want a protein bar
Individually portioned bars can go into separate party bags for adults who want this type of snack. Check the exact bar’s age statement, ingredients and allergens before assigning it to a guest.
Who are the bars for?
Hosts catering for vegan or gluten-free guests
A separately identified flapjack may meet those stated requirements. The TREK Peanut Butter example listed by Tesco is vegan and gluten-free but contains peanuts and soya and may contain nuts and milk, so its other allergen information still matters.
Hosts with mixed-age or allergy-sensitive guest lists
One unlabelled assortment cannot account for every guest’s requirements. Check age warnings and the current wrapper for each flavour, then keep different options identifiable.
What should you check before buying?
Start with who can have each bar, then choose a flavour and pack format that work for the guests receiving it.
| Priority | What to check | Your needs |
|---|---|---|
| Age suitability | Read the age statement on the exact pack. Grenade UK labels its Birthday Cake bar as unsuitable for children under 14. | If children are coming, I need to allocate age-suitable food rather than assume a birthday flavour is intended for them. |
| Allergens and dietary claims | Check ingredients, declared allergens and any ‘may contain’ wording for each flavour. Check vegan and gluten-free claims separately from allergy requirements. | Guests with different requirements need clearly identified options; I cannot rely on a single mixed assortment. |
| Flavour and party appeal | Choose flavours guests are likely to want, then check whether coatings or fillings introduce ingredients they must avoid. | I want the bar to feel like a birthday treat, but flavour cannot take priority over suitability. |
| Protein per portion | Compare the stated amount per bar, along with bar size. Grenade UK states 20 g per 60 g Birthday Cake bar; Tesco lists 9 g per 50 g TREK Peanut Butter flapjack. | For protein-focused adults, I want to compare individual portions rather than judge a box by its front label. |
| Portions and serving warnings | Count suitable recipients before choosing a pack size. Read sweetener and polyol warnings; the checked Grenade Birthday Cake, Barebells White Chocolate Almond and PhD Dark Choc Raspberry products carry excessive-consumption laxative-effect warnings. | I need a sealed portion for each suitable guest without encouraging repeat servings from a shared bowl. |
Party-bag mistakes to avoid
-
Assuming a birthday flavour suits children
Grenade UK explicitly labels its Birthday Cake bar as unsuitable for children under 14. Its flavour and individual wrapping do not change that restriction.
For children under 14, do not use that exact bar; check the current packaging and dietary suitability of an alternative.
-
Using dietary claims as an allergy check
Tesco’s vegan and gluten-free TREK Peanut Butter flapjack contains peanuts and soya and may contain nuts and milk. Barebells UK lists milk, almonds and soya in its White Chocolate Almond bar.
Read the full statement for each flavour, and keep bars for different guests separately identified.
-
Leaving warned-about bars in an unrestricted snack bowl
The checked Grenade Birthday Cake, Barebells White Chocolate Almond and PhD Dark Choc Raspberry products carry warnings about laxative effects from excessive consumption.
Give each suitable guest a labelled portion and retain its wrapper so the warning remains available.

Grenade Oreo Flavour Protein Bars, 4 × 60 g
The four-bar pack is a quantity to consider for a small group of suitable adult guests. Check each guest’s requirements against the exact wrapper, including its allergen and serving information.
No image available
Grenade Jaffa Quake Protein Bars, 12 × 60 g
The 12-bar box could supply separate bags for guests who can have this flavour. Check its current milk, soya and polyol information before distribution; pack size does not establish how many guests can receive it.

TREK Salted Caramel Protein Flapjacks, 3 × 50 g
This three-flapjack pack offers a different format from the Grenade bars. If buying it for vegan or gluten-free guests, confirm those claims and the full allergen statement on this Salted Caramel pack; the Peanut Butter variant’s label does not establish this variant’s ingredients.

Grenade White Chocolate Salted Peanut Flavour Protein Bars, 12 × 60 g
Consider this 12-bar box only for recipients whose requirements have been checked against the exact peanut-flavoured bar. Keep it out of an unlabelled mixed assortment, and check the current wrapper for its age and allergen statements.

Grenade Peanut Butter Protein Bars, 12 × 60 g
The 12-bar box is another option for individually planned adult party bags, not for an unmarked shared selection. Confirm guests’ peanut requirements and check the exact wrapper for other allergens before allocating bars.
Frequently asked questions
Can every guest have the same protein bar?
Not by default: the checked bars have different age and allergen statements. Grenade UK labels its Birthday Cake bar as unsuitable for children under 14, while the checked dairy bars and TREK Peanut Butter flapjack contain or may contain allergens relevant to different guests. Confirm recipients’ requirements and identify each suitable option separately.
What should I check on a protein-bar wrapper?
Read the current ingredients, declared allergens, precautionary ‘may contain’ statements and any age or serving warnings for the exact flavour. The Food Standards Agency’s guidance for UK food businesses distinguishes listed allergens used as ingredients; a vegan or gluten-free claim does not answer every separate allergy question.
Is a vegan and gluten-free flapjack suitable for every allergy?
No. Tesco lists its TREK Peanut Butter Protein Flapjack as vegan and gluten-free, but it contains peanuts and soya and may contain nuts and milk. Check the current label of the flavour you intend to serve against each guest’s requirements.
Can guests take several lower-sugar protein bars?
Check the warning on the particular product before setting it out for repeat servings. The checked Grenade Birthday Cake, Barebells White Chocolate Almond and PhD Dark Choc Raspberry bars carry excessive-consumption laxative-effect warnings; a labelled single portion keeps that information with the bar.
How many bars should I put in party bags?
Plan one sealed portion for each guest confirmed as suitable for that exact bar, then choose the pack quantity. Check ages, dietary preferences and allergens before using the total guest count to work out how many of each option you need.
