Day hikers comparing protein per bar
If pack space matters, compare the protein in one bar rather than relying on the word ‘protein’ on the front. The British Mountaineering Council also advises taking enough food and drink for the whole day.
Who these bars may suit
A protein bar can be a convenient item to pack, but the useful choice depends on the rest of your food, the route and any ingredients you need to avoid.
Hikers looking for plant-based options
TREK states 15g plant-based protein for its High Protein bars and 9g for its Protein Flapjacks. These are different product lines, so check the exact bar you intend to pack.
Hikers checking dietary restrictions
Read the ingredients and allergen statement for the exact flavour and pack. A gluten-free or plant-based description does not tell you whether a bar contains nuts, soya or other ingredients you avoid.
What to check before choosing
Start with the amount in one bar, then consider how that bar fits the food you are carrying and whether its ingredients are suitable for you.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per bar | Compare grams of protein and bar weight for the exact product. TREK states 15g per High Protein bar and 9g per Protein Flapjack; Nature Valley lists around 10g per 40g Peanut & Chocolate bar. | I want to know what one bar contributes, rather than choosing by its product-line name alone. |
| Food for the route | Read energy per bar alongside the rest of your packed food. The British Mountaineering Council advises allowing for route duration, terrain and weather, carrying enough food and drink, and taking emergency food. | For a longer or more demanding walk, I need a plan for meals, regular snacks and water—not just a protein bar. |
| Ingredients and allergens | Check the current ingredients, allergen information and any precautionary statements for the exact flavour. Check dietary descriptions on that product rather than another bar from the same brand. | If I avoid nuts, soya, milk or gluten, the specific pack matters more to me than a broad brand description. |
| Carrying portion | Compare the number and weight of bars in the pack with the portions you intend to carry. Check the storage instructions for the product you buy. | I would rather pack the portions I expect to use and keep emergency food separate. |
Packing and buying mistakes to avoid
-
Assuming every ‘protein’ bar provides the same amount
TREK states 15g per bar for its High Protein range but 9g for its Protein Flapjacks. The name alone does not show the portion you will get.
Compare protein grams and bar weight on the current pack before choosing a flavour or format.
-
Packing a bar in place of enough food and water
Food needs vary with the distance, terrain and weather. The British Mountaineering Council advises carrying enough food and drink, snacking regularly and bringing emergency food.
Plan for the full route, and treat the bar as one part of what you carry.
-
Treating gluten-free as free from other allergens
The researched bars have different ingredient and precautionary allergen statements. A gluten-free description does not address nuts, soya or milk.
Read the full current label for the exact flavour and pack size, including any ‘may contain’ wording.
-
Relying on an old pack or product list
A Weetabix Food Company product list from November 2021 names Alpen Protein Bars, but an older list cannot establish the nutrition or ingredients of a pack bought now.
Check the current pack details when buying a familiar bar again or trying a different flavour.

Hiking snack-bar questions
Is a protein bar enough food for a hike?
Not on its own. The British Mountaineering Council advises carrying enough food and drink for the day, snacking regularly and taking emergency food; plan for your route, terrain and weather.
Do all protein bars contain the same amount per bar?
No. TREK states 15g protein per High Protein bar and 9g per Protein Flapjack, while Nature Valley UK describes its 40g Peanut & Chocolate bar as providing around 10g. Check the stated serving size when comparing packs.
Which of these bars should a vegan hiker check?
TREK describes its bars as plant-based, including its High Protein and Protein Flapjack ranges. The nākd. Protein Cocoa Hazelnut bar is another plant-based option; confirm the dietary information and allergens on the exact pack you choose.
Does gluten-free mean a bar is suitable for someone avoiding nuts or soya?
No. Gluten-free status does not address other allergens. Nature Valley Protein Peanut & Chocolate contains peanuts and soya, so read the full current ingredient and allergen statement for every flavour under consideration.
Do I need specialist hiking food?
No. The British Mountaineering Council says ordinary foods such as sandwiches, snacks and fruit can form part of what you take. Carry enough food and drink for the route and conditions, including emergency food.
