Regular snackers stocking up
A multipack can put individually wrapped portions within reach for work or travel. Compare the number of bars with protein per bar: a larger box does not, by itself, tell you what each snack provides.
Who is buying in bulk?
Vegan or gluten-free buyers
TREK and nākd. have vegan and gluten-free examples, but their protein amounts and pack formats differ. Check the exact product rather than applying a brand-level description to every flavour.
Buyers checking ingredients and allergens
Peanuts, other nuts, soya and milk appear in the ingredients or precautionary statements of the products discussed here. Read the label for the flavour and pack you intend to buy before ordering several.
What should you compare?
Start with what one bar provides, then decide whether the pack size fits how often you will eat it. Nutrition and allergen checks matter just as much when you are committing to multiple bars of the same product.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per bar | Read the amount for one bar, not just per 100 g or the word “protein” on the front. Nature Valley states about 10 g per 40 g bar for its Peanut & Chocolate Big Pack; Ocado lists around 9 g per bar for the TREK Protein Flapjacks Variety Pack. TREK describes a separate High Protein line as containing 15 g per bar. | I want to know what each snack provides, rather than choosing the largest box or assuming similarly named TREK lines have the same amount. |
| Pack size | Confirm the bar count, weight per bar and best-before date. The Nature Valley Big Pack has eight 40 g bars; the TREK variety pack has 16 50 g flapjacks. | A larger pack works for me only if I will use the bars before their best-before date. Individually wrapped portions may matter if I take them to work or on journeys. |
| Per-bar nutrition | Compare sugars, saturated fat and energy using the same serving basis. Nature Valley lists about 6.8 g sugars per 40 g Peanut & Chocolate bar; the reviewed TREK Cocoa Oat flapjack lists 14 g sugars per 50 g bar. Check the figures for the flavour you are buying. | If these will be regular snacks, I want the figures for a whole bar, not a protein claim in isolation. |
| Diet and allergens | Check the exact flavour’s ingredients and “may contain” statement. Nature Valley Peanut & Chocolate contains peanuts, soya and milk; reviewed vegan nākd. bars also contain peanuts. Vegan and gluten-free descriptions do not answer every allergen question. | I need a bar that fits my dietary requirements, with allergen information I can check again on the pack I receive. |
What can catch you out?
-
Assuming every “protein” bar provides the same serving
A larger pack can contain bars with less protein per serving than another product. The reviewed TREK flapjack pack provides around 9 g per bar, while TREK states 15 g for its separate High Protein line.
Compare the amount for one bar and make sure the nutrition panel belongs to the line and flavour in your basket.
-
Checking protein but skipping the rest of the label
The reviewed Nature Valley Peanut & Chocolate bar lists about 6.8 g sugars per 40 g bar, while the reviewed TREK Cocoa Oat flapjack lists 14 g per 50 g bar. The serving sizes differ, so neither figure should stand in for the other product’s label.
For a repeat purchase, read sugars, saturated fat and energy per bar alongside protein.
-
Treating vegan or gluten-free as an allergen check
The reviewed vegan nākd. bars contain peanuts, and precautionary allergen statements vary by product. A dietary description does not replace the ingredient list for a specific flavour.
Check the highlighted ingredients and “may contain” wording on the current pack before buying several.
Relevant brand references
These examples illustrate different bar types and pack questions; a brand’s other flavours or product lines may have different ingredients and nutrition.
Nature Valley
Nature Valley’s Peanut & Chocolate Protein Big Pack is an eight-bar option with stated nutrition per 40 g bar.
- Nature Valley states approximately 10 g protein and 4 g fibre per bar.
- This product contains peanuts, soya and milk and may contain tree nuts.
TREK
TREK offers protein flapjacks and a separate High Protein bar line; their stated protein amounts should not be interchanged.
- Ocado lists a 16 × 50 g vegan, gluten-free Protein Flapjacks Variety Pack with around 9 g plant protein per bar.
- TREK’s stated 15 g protein figure applies to its separate High Protein bars, not that flapjack variety pack.
nākd.
The reviewed fruit-and-nut protein bars offer vegan and gluten-free choices, including a three-bar Peanut Butter multipack.
- Tesco lists approximately 7–7.6 g plant protein per 45 g bar for the reviewed products.
- The reviewed bars contain peanuts; check each flavour for other nuts and precautionary statements.
Eat Natural
Eat Natural lists nut-led protein-bar variants and indicates multipack availability for some products.
- Its reviewed 40 g bars list 7.3 g or 7.8 g protein, depending on the recipe.
- The reviewed recipes contain peanuts, and the exact multipack size needs checking for the product chosen.
Graze
Graze describes plant protein as one possible feature across its wider snack range.
- For a protein-focused bulk purchase, compare the exact bar’s protein per serving, ingredients and pack count rather than relying on the wider range description.
Alpen
Alpen Protein Bar Chocolate has appeared in a 5 × 34 g retailer listing.
- Check the current product listing and pack label before using an older listing as a repeat-buy reference; ingredients and nutrition can change.

Common questions
Does “protein bar” tell me how much protein I will get?
No. Compare the amount for one bar on the exact product label: Nature Valley states about 10 g for its 40 g Peanut & Chocolate Big Pack bar, while the TREK Protein Flapjacks Variety Pack is listed at around 9 g per bar. TREK’s stated 15 g figure belongs to a separate High Protein line.
Should I choose eight bars or a 16-bar pack?
Choose by both serving and use rate. Nature Valley’s eight-bar Peanut & Chocolate pack provides about 10 g protein per 40 g bar; the 16-bar TREK Protein Flapjacks Variety Pack provides around 9 g per 50 g bar and is listed as vegan and gluten-free. Check the best-before date before ordering more bars than you expect to use.
Are vegan protein bars suitable for someone avoiding nuts?
Not necessarily. The reviewed vegan nākd. protein bars contain peanuts, and precautionary statements differ between products. Read the ingredients and “may contain” wording for the exact flavour and current pack.
Why check the label again when reordering?
Ingredients and nutrition can change. Check the pack you receive for its current serving figures and allergens, especially if you are switching flavours or buying several packs at once.
How should I store a supply of snack bars?
Follow the directions and best-before date on the pack. The reviewed Nature Valley and TREK product information specifies cool, dry storage; check the instructions for the exact bars you buy.
