If you have not settled on a flavour, a selection box is a more cautious first purchase than a full case of one flavour. If you already know what you like, compare the exact bar size, protein per serving, ingredients and checkout total before buying a larger pack. A protein bar can be a TV-evening snack, but its protein content alone does not make it a complete dinner.
The right pack size depends as much on whether you know the flavour as on how regularly you want a bar.
If you want an individually portioned snack while watching television but have not chosen a favourite flavour or texture, consider a selection box first. Check its stated contents: Grenade says flavours in its selection box can vary.
If you already use bars regularly, compare the number of bars, weight and labelled protein per serving for the exact flavour. Then check the final checkout total for a pack size you will use.
If vegan suitability or avoiding an allergen is essential, choose by the exact product and flavour rather than the brand alone. PhD describes Smart Plant as suitable for vegans and vegetarians; that description does not apply automatically to its standard Smart Bar.
Decide whether you are testing a snack or stocking up on one you know, then compare the pack and the individual bar on the same basis.
| Priority | What to check | Your needs |
|---|---|---|
| Flavour and texture | Check how many flavours are listed, whether the mix can change and whether the bars have a texture you already enjoy. | I would rather try several flavours before committing to a case of one. If I want a particular bar, I need to confirm it is in the box. |
| Protein per bar | Read protein, energy and weight for the exact serving. PhD lists 21g protein and 250kcal for its 64g Smart Bar Choc Brownie; Barebells lists 20g protein for its 55g Caramel Cashew bar. Those figures describe the cited flavours, not every bar in either range. | Protein per serving matters to me, but I also want to know the size of the bar I am buying. |
| Pack commitment | Count the bars and distinguish a selection box from a single-flavour pack. A smaller pack lets you try a named flavour before buying more of it. | I am happy with a case if I know I will eat the flavour; otherwise, I would start with fewer bars or a mixed box. |
| Final cost | Compare the checkout total for the quantity you intend to order, including delivery, then calculate the cost per bar. Grenade states a UK delivery charge of £5.95 on orders below £40. | I want the pack I will actually use to make sense after delivery, not just on the box listing. |
| Ingredients and suitability | Check the exact flavour’s ingredients, allergens, dietary designation and any sweetener or excessive-consumption warnings. GOV.UK guidance says pre-packed food labels must include ingredients, including allergens, and a date mark. | If an ingredient or dietary requirement affects my choice, I need to check this particular bar before buying a case. |
Pack counts and delivery conditions can differ, so the apparent cost per bar may not reflect what you pay at checkout.
Compare the final total for the quantity you intend to buy, then divide it by the number of bars.
Grenade states a UK delivery charge of £5.95 on orders below £40; include it when considering a single selection box.
A single-flavour case commits you to the same bar throughout. Even a selection box may not guarantee every flavour: Grenade and Myprotein say their box contents can vary.
Try a smaller pack or check the selection-box contents before buying a larger quantity.
Sweetener and excessive-consumption warnings, allergens and dietary suitability need separate checks. The cited PhD and Barebells bars carry warnings about laxative effects from excessive consumption.
Read the ingredients and warnings for the exact flavour, especially when a formulation changes.
The cited Barebells Caramel Cashew bar lists 20g protein per 55g bar, while PhD lists 21g per 64g Smart Bar Choc Brownie. A front-of-pack category name does not tell you either serving size.
Compare the nutrition panels for the specific bars you are considering.
These examples show different ways to try flavours or buy a familiar bar; check the individual product rather than treating a brand description as a specification for every flavour.
Grenade offers a 12-bar selection box as well as larger bundles.
PhD lists standard Smart Bar 12-packs and a separate Smart Plant 12-pack.
Barebells offers a 12-bar selection box containing four flavours.
Myprotein’s Protein Snack Box mixes bars with other protein snacks.
Tesco lists protein bars in single-bar and multipack formats.
These options include single-flavour 12-packs for a known preference and a four-pack for trying Grenade Oreo without committing to a larger case. Check each flavour’s label and the checkout total before ordering.

A 12-pack for shoppers who already want the Oreo flavour as a TV-evening snack. Each listed bar is 60g; check the flavour’s ingredients and warnings before buying the case.

This 12-pack suits someone choosing Chocolate Peanut Butter rather than a mixed box. Each listed bar is 64g; check the exact flavour’s ingredients if allergens affect your choice.
No image available
A 12-pack for shoppers seeking the named Soft Core Double Chocolate variant. Each listed bar is 50g; compare its own nutrition panel with 60g or 64g bars rather than assuming equal servings.
No image available
The four-pack offers a smaller commitment if you want to try Oreo before considering the 12-pack. Each listed bar is 60g; compare the checkout totals for the quantities you would actually use.
Do not treat protein content alone as evidence that a bar is a complete evening meal. The cited products are presented as snacks; if you need dinner, consider the meal separately from your choice of TV snack.
Check the final checkout total for each pack and divide it by the number of bars, comparing quantities you would actually use. Delivery can change the result: Grenade states a UK delivery charge of £5.95 on orders below £40.
Read the exact flavour’s ingredients, allergens, quantity, date mark and nutrition panel before buying several bars. GOV.UK guidance says pre-packed food labels must include an ingredient list with allergens, the food’s weight or volume, and a best-before or use-by date.
No. Check sweeteners, allergens and any excessive-consumption warning separately for the exact flavour. The cited PhD and Barebells products warn that excessive consumption may have laxative effects.
PhD describes its Smart Plant Protein Bar 12-pack as suitable for vegans and vegetarians. It is a separate product from the standard Smart Bar, so check the chosen flavour’s own label and checkout total.
