For a top-up shop, choose a protein snack bar by its amount per individual bar, then check sugars, dietary suitability and allergens rather than relying on the name alone. Nature Valley Peanut & Chocolate is a compact option at around 10g protein per 40g bar; a TREK Protein Flapjack offers a plant-based alternative, while nākd. Cocoa Hazelnut meets vegan and no-added-sugar preferences but still lists 13g sugars per bar.
An individually portioned bar is convenient to carry, but compare the protein in the bar you will actually eat. Nature Valley UK describes its Peanut & Chocolate bar as providing around 10g protein per 40g bar; a TREK Protein Flapjack is a different, 50g portion.
Check the declaration on the exact flavour. Tesco lists nākd. Protein Cocoa Hazelnut as vegan and dairy-free, while TREK describes its bars as plant-based. Those descriptions do not replace a check of the ingredients and allergen statement.
No added sugar and sugar-free mean different things. Tesco lists 13g sugars per 45g nākd. Protein Cocoa Hazelnut bar despite its no-added-sugar description, so the sugars line still matters.
Start with the portion you plan to eat, then read the rest of that product’s nutrition and ingredient information before choosing a flavour or multipack.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per bar | Compare grams per individual bar and its weight, not just a range name or multipack quantity. TREK’s Protein Flapjacks and separate High Protein bars should not be treated as the same product. | I want to know what one snack provides. Nature Valley UK puts Peanut & Chocolate at around 10g protein per 40g bar; TREK describes its Protein Flapjacks as providing 9g plant protein per 50g flapjack. |
| Sugars and other values | Read sugars, saturates, fibre and energy for the same portion. A no-added-sugar description does not mean zero sugars. | If I am comparing fruit-and-nut bars, the sugars line matters alongside protein: Tesco lists 13g sugars and 7.2g protein per 45g nākd. Cocoa Hazelnut bar. |
| Dietary suitability | Check vegan, dairy-free or gluten-free wording on the exact product and flavour. Do not transfer a declaration from one bar in a range to another. | I need the bar I put in my basket to match my dietary requirements, rather than assuming every protein-positioned bar from a brand is suitable. |
| Allergens | Read the current pack’s ingredients and may-contain statement, including peanuts, tree nuts, soy and milk where relevant. | For an allergy, I need to check each flavour and pack. Nature Valley identifies peanuts, soy and milk in Peanut & Chocolate and says the recipe information on the pack should be checked. |
The amount applies to a particular bar and portion: TREK’s Protein Flapjacks are not its separate High Protein range.
Compare the grams of protein per individual bar, then check the other nutrition values on that same product.
