Choose a snack-bar multipack according to who will eat it and when: compare the nutrition per 100g and per bar, then check the ingredients and allergens of every flavour. Smaller oat-bar packs may suit routine desk or lunchbox snacks, while protein-focused packs serve a different preference; neither a protein, fibre nor no-added-sugar claim tells you everything about the bar.
Check how many bars the pack contains, the weight of each serving and whether its flavours will work for the people sharing it. In a variety pack, read each recipe rather than assuming the bars have identical nutrition or ingredients.
Look at the stated amounts per bar alongside sugars, saturated fat and energy. Bars with different serving weights need a per-100g comparison as well as a per-bar one.
Check the current packaging for every flavour. A vegan, gluten-free or dairy-free description does not answer questions about other ingredients, such as peanuts or soya.
Start with the people sharing the pack, then compare serving sizes and labels before deciding how many bars to put in the weekly shop.
| Priority | What to check | Your needs |
|---|---|---|
| Nutrition | Compare energy, sugars, saturated fat and salt per 100g, then check the amount per bar. Read the full nutrition panel alongside any traffic-light label or front-of-pack claim. | I want to compare different recipes fairly, but I also need to know what one wrapped serving contains. |
| Protein and fibre | Check the grams per bar and its weight; compare other nutrition values on the same serving basis. For example, Nature Valley UK lists around 10g protein per 40g Protein Variety bar, while Tesco lists 9g per 50g TREK Cocoa Oat Protein Flapjack. | If protein or fibre is a reason for choosing the pack, I want the amount for the bar I would actually eat—not just a claim on the front. |
| Ingredients and allergens | Read the current ingredients and allergen statements for every flavour, including any ‘may contain’ wording. Confirm dietary claims on the exact pack. | Everyone sharing the bars needs to be able to check the recipe that applies to their own serving, especially where an allergy is involved. |
| Pack and flavours | Count the bars, check each bar’s weight and identify the flavours included. Confirm whether individual wrapping matters for how the household will use them. | Will these servings cover the snack occasions I am shopping for, and will people use each flavour? |
A fibre or no-added-sugar claim does not describe every nutrition value. Action on Sugar reported that, in its 2025 UK snack-bar product audit, 31% of bars carrying a high-fibre claim were also high in sugars under voluntary traffic-light criteria. Tesco lists 13g total sugars per 45g nākd. Peanut Butter Protein bar despite its no-added-sugar description.
Compare the nutrition panel per 100g and per bar, and read the ingredients behind the claim.
Recipes within a variety pack can differ. Nature Valley UK lists peanuts, soya and milk in its Protein Variety Bars and warns that they may contain tree nuts.
Read the current ingredients and allergen information for each flavour before sharing the pack.
The cited multipacks contain three or four bars, with individual weights ranging from 30g to 50g. Pack count alone therefore does not tell you how large each serving is.
Check the number of bars, total weight and weight per bar against the week’s planned snack occasions.
Alpen Muesli lists several former Alpen bar products as no longer being made, so a familiar name does not identify a current multipack.
Check the exact current listing and its pack label before treating it as an option for the weekly shop.
These ranges offer different bar formats; check the exact product rather than applying one recipe’s details to an entire brand.
Graze offers Oat Boost flapjacks, including a Sticky Toffee pack of four 30g bars listed by Tesco.
Nature Valley UK lists Crunchy family and variety packs alongside Protein Variety Bars.
Eat Natural has nut-based bars, including a Maple Syrup, Pecans & Peanuts pack of three individually wrapped 40g bars listed by Sainsbury's.
nākd. offers fruit-and-nut bars as well as protein and fruit-and-fibre ranges.
TREK has oat-based protein flapjacks, including a Cocoa Oat multipack of three 50g bars listed by Tesco.
Alpen is a familiar name to check carefully when an older bar product appears in a shopping list.
These options cover Nature Valley protein bars and Graze oat-bar multipacks. Compare their pack counts and flavours with the needs of the people sharing them; check each current pack for nutrition and allergens.

An eight-bar pack to consider when several peanut-and-chocolate servings are wanted during the week. Each bar is listed as 40g; check the current label for nutrition and allergens.
No image available
A four-bar peanut-and-chocolate pack if fewer servings fit the week’s plans. Compare the 40g serving with other bar sizes and read the current nutrition and allergen label.

This four-bar pack offers a salted-caramel-and-nut flavour rather than a mixed-flavour selection. Each bar is listed as 40g; check the exact nut ingredients and other allergens on the current pack.

Four 30g oat bars offer a different serving size from the 40g protein bars above. Choose the lemon-and-blueberry flavour if it suits the household, and check the current ingredients and allergen statement.

This four-bar oat pack keeps the 30g serving size but offers a Cherry Bakewell flavour. Check its own nutrition and ingredients rather than applying the figures for another Graze flavour.
Use both: per 100g puts recipes on the same basis, while per bar shows the amount in one serving. The NHS notes that labels give nutrition information per 100g and sometimes per portion; the portion printed by a manufacturer may differ from the amount you eat.
No. Tesco lists the no-added-sugar nākd. Peanut Butter Protein bar as containing 13g total sugars per 45g bar. Check total sugars, serving size and ingredients on the exact pack.
No. Choose one if its stated protein amount and serving size fit what you are looking for, then compare the rest of its nutrition and ingredients. Nature Valley UK lists around 10g protein per 40g Protein Variety bar, but that figure alone does not describe its sugars, saturated fat or allergens.
Read the current ingredients and allergen statements for every flavour, including ‘may contain’ warnings. GOV.UK guidance says prepacked foods must clearly label any of the 14 regulated allergens they contain in the ingredients list. Nature Valley UK, for example, lists peanuts, soya and milk in its Protein Variety pack and warns that it may contain tree nuts.
Follow the storage and best-before instructions on the specific pack. If someone needs its allergen information, keep the relevant wrapper available until that bar has been eaten.
