Who is each pack for?

Organisers sharing with a group

If guests have different flavour preferences, a mixed box provides several choices from one pack. Check whether its stated mix is fixed and whether every bar is suitable for the people sharing it.

People who want a repeatable snack

A same-flavour pack suits regular lunches or a picnic group that already agrees on a flavour. Compare the nutrition information per bar for the exact variant, rather than applying another flavour’s figures to the whole range.

Shoppers checking dietary suitability

Ingredients and allergen warnings can differ between bars and flavours. Read each physical wrapper before sharing, particularly where a guest needs to avoid a specific ingredient or allergen.

What should you check before buying?

Choose the pack format around the number of people and their flavour preferences, then check the individual bars before they go into the picnic bag.

Mixed-flavour box

Choose when: several people want a choice of flavours from one box.

Bear in mind: Grenade says its selection-box flavours can vary; Myprotein’s listed variety box is marked not suitable for vegetarians.

Same-flavour multipack

Choose when: the group agrees on a flavour or you want bars for several lunches.

Bear in mind: a whole pack offers no flavour choice if someone dislikes that bar.

Individual bars

Choose when: you need only one or two additions or want people to select their own flavours.

Bear in mind: a single bar does not provide a ready-made selection for a group.

PriorityWhat to checkYour needs
Portions and flavours Count the bars and compare the stated flavour mix. Check whether substitutions are possible: Grenade says its Selection Box flavours can vary. I’m packing for several people and want enough bars without relying on one flavour everyone may not like.
Protein per bar Compare figures for the exact flavour and portion size. PhD lists 21g protein per 64g Chocolate Brownie bar; Myprotein lists 20g per 60g Triple Chocolate serving in its variety box. A stated amount per portable bar matters to me more than a figure that applies to a different flavour.
Nutrition and sweeteners Read sugars, saturates, fibre and the serving size on the exact bar’s panel. Check the ingredients and any excessive-consumption warning rather than relying on a front-of-pack claim. I want to compare the bars I’ll actually pack and know about any tolerance warning before buying a case.
Allergens and diet Inspect each wrapper’s ingredients, allergen statement and dietary labelling. Myprotein marks its listed Layered Bar Variety Box not suitable for vegetarians. Someone sharing the picnic may need to avoid an ingredient, so suitability has to be checked bar by bar.
Storage and the rest of lunch Follow the chosen pack’s storage directions. Myprotein says to keep its Layered Bar Variety Box cool and dry, away from direct sunlight; consider what other foods you are packing. I need bars that I can pack as directed, alongside the other parts of our picnic lunch.

Picnic packing mistakes to avoid

  • Assuming every variety box has a fixed mix

    Grenade says the flavours in its Selection Box can vary, while Myprotein lists flavour counts for its Layered Bar Variety Box. A particular flavour may therefore be harder to plan around in one format than the other.

    If guests have firm preferences, check the current assortment and whether substitutions are mentioned before choosing a box.

  • Judging a bar by one front-of-pack claim

    In its November 2025 review of 458 snack bars from 10 major UK retailers, Action on Salt & Sugar classified 55% as high in saturated fat and 37% as high in sugars under UK front-of-pack thresholds. That audit covers snack bars, not every protein bar or any particular picnic pack.

    Compare the nutrition panel and portion size for the exact flavour, including sugars and saturates, rather than treating a protein or no-added-sugar claim as a description of the whole bar.

  • Applying one flavour’s allergen information to the range

    Grenade identifies peanut-containing flavours, Myprotein marks its listed Layered variety box not suitable for vegetarians, and Tesco’s Barebells Cookies & Cream listing contains milk proteins. The brand name alone cannot establish suitability for a guest.

    Read every relevant wrapper before sharing, even if you have bought another flavour from the same brand before.

  • Buying a case without checking its consumption warning

    PhD’s Smart Bar page and Tesco’s Barebells Cookies & Cream listing warn that excessive consumption may have laxative effects. That matters when several bars are being packed for the same day.

    Check the warning on the exact pack and let guests choose whether they want a bar alongside the other picnic foods.

Brand and retailer references

These examples show how pack formats and product lines differ; a brand reference does not establish that every flavour has the same label.

Grenade

Grenade lists a Selection Box of 12 bars in 12 named flavours for people considering a mixed group pack.

  • One box provides several flavour choices.
  • Grenade says flavours can vary and lists allergen and possible-trace warnings; check the bars that arrive.

PhD

PhD’s Smart Protein Bar 12-pack is a same-flavour option for repeat portions rather than a mixed selection.

  • Its Chocolate Brownie panel states 21g protein and 1.2g sugars per 64g bar.
  • PhD warns that excessive consumption may cause laxative effects; figures for Chocolate Brownie should not be assumed for another flavour.

Myprotein

The Layered Bar Variety Box lists 12 bars across five flavours.

  • The listed mix gives flavour counts, including three Triple Chocolate Fudge bars.
  • The box is marked not suitable for vegetarians and should be stored cool and dry, away from direct sunlight.

Barebells

Barebells has several bar lines, while Tesco’s Cookies & Cream listing provides an example of a 55g single bar.

  • Tesco’s Cookies & Cream panel lists 20g protein per 55g bar.
  • That listing contains milk proteins and warns of possible gluten-containing cereals, soya, peanuts and nuts.

Tesco

Tesco’s grocery listings include individual bars and selected branded multipacks, offering a way to consider smaller quantities.

  • Its listings provide examples of both single bars and a Grenade four-pack.
  • Tesco advises reading the physical label because ingredients, nutrition and allergen information can change.

Quest

Quest describes protein-bar multipacks and variety packs on its US storefront; that does not establish a UK picnic-buying option or UK label details.

  • Its own product-line information identifies variety-pack and multipack formats.
  • Check the label on any UK product under consideration rather than applying information from the US range.

Joybuy multipacks for a picnic

Grenade Oreo protein bars, 12 x 60g pack

Grenade Oreo Protein Bars, 12 x 60g

Twelve bars provide portions for a group that wants Oreo flavour throughout, rather than a mixed selection. Check each wrapper for ingredients and allergens before sharing.

PhD Smart Protein Nutrition Bar Salted Caramel, 12 x 64g

This same-flavour 12-pack suits a picnic group that has agreed on Salted Caramel. Check the exact bars’ nutrition, allergen information and consumption warning; figures for PhD’s Chocolate Brownie variant do not describe this one.

PhD Smart Protein Nutrition Bar Chocolate Peanut Butter Flavour, 12 x 64g pack

PhD Smart Protein Nutrition Bar Chocolate Peanut Butter, 12 x 64g

Picnic protein-bar questions

Should a protein bar be the whole picnic lunch?

Treat it as a portable part of lunch rather than judging the meal by that bar alone. NHS guidance describes dietary balance across a day or week and recommends variety across food groups, including fruit and vegetables and higher-fibre starchy foods.

What should I check before sharing a mixed box?

Check the flavours actually supplied and read each wrapper’s ingredients and allergen statement. Grenade says its Selection Box flavours can vary and warns of allergens and possible traces, so the box name alone cannot establish that every bar suits every guest.

Why read the wrapper if I have checked the bar online?

The physical wrapper gives the information for the bar being packed. Tesco advises reading it rather than relying solely on a website listing because ingredients, nutrition, dietary information and allergens may change.

Can protein bars stay in a picnic bag?

Follow the storage directions for the particular pack. Myprotein says its Layered Bar Variety Box should be kept in a cool, dry place away from direct sunlight, so do not leave that box in direct sun while setting up the picnic.

Do any bars carry a consumption warning?

Yes. PhD’s Smart Bar page and Tesco’s Barebells Cookies & Cream listing warn that excessive consumption may have laxative effects. Read the warning on the exact bar before packing several for one person.
