After exercise lasting more than an hour, if a meal is not coming soon, compare the protein in one bar with the British Heart Foundation’s 15–30g post-exercise guidance rather than relying on the word ‘protein’ on the wrapper. A bar below that range can still contribute to a snack, but consider what other protein-containing food and carbohydrate you will have; a bar does not automatically replace a meal.
If you have exercised for more than an hour and cannot eat a meal soon, protein per bar matters more than a protein claim alone. The British Heart Foundation cites 15–30g of protein after sessions of that length; consider carbohydrate alongside your protein choice.
A portable plant-based bar may fit your food preferences, but ‘vegan’ and ‘vegetarian’ do not mean the same thing. TREK and nākd. have vegan options; check the particular flavour and its allergen information.
If you buy bars regularly or need to avoid particular ingredients, read the sugars and saturates figures per bar as well as the ingredients and any ‘may contain’ wording. A protein claim does not answer those questions.
Start with the amount in one bar and when you expect to eat next. Then compare the rest of the nutrition panel and ingredients for the exact variety.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per bar | Read grams per bar, not just per 100g or per multipack. For exercise lasting more than an hour, the British Heart Foundation cites 15–30g of protein afterwards; TREK states 15g for its High Protein range but 9g for its Protein Flapjacks. | If my next meal is some way off, I want to know how much protein one bar contributes and whether I will have another protein-containing food. |
| The rest of the snack | Consider the carbohydrate in the bar and what you plan to eat and drink after training. A protein figure alone does not describe a complete meal. | After a longer session, I need to think beyond the bar rather than assume it covers everything I intend to have afterwards. |
| Nutrition per serving | Compare sugars, saturates and energy for the bar you will eat. Check the serving size: the Eat Natural Peanuts & Dark Chocolate bar lists 10g sugars per 40g bar, while the nākd. Cocoa Hazelnut bar lists 13g per 45g bar despite having no added sugar. | For a snack I might buy often, I want the full per-bar figures, not just a front-of-pack description. |
| Dietary fit | Read the current ingredients and ‘may contain’ statements for the exact flavour. Vegan or gluten-free wording does not establish that a bar is free from nuts, soya or milk cross-contact. | If an ingredient or possible cross-contact matters to me, I need to check the pack each time, including when I change flavours. |
A 7–10g bar contributes protein, but on its own it falls below the British Heart Foundation’s cited 15–30g range after exercise lasting more than an hour. It is not a complete meal by virtue of its name.
Check grams per bar and consider your next meal. If you need more protein before then, plan another suitable food and consider carbohydrate too.
The nākd. Cocoa Hazelnut bar is described as having no added sugar but lists 13g sugars per 45g bar.
Read the ‘of which sugars’ figure for the portion you will eat, alongside any front-of-pack wording.
Those descriptions do not cover every ingredient or possible cross-contact. The bars discussed here include varieties with peanuts, soya, milk or nut warnings.
Check the ingredients and ‘may contain’ statement on the current pack against the substances you need to avoid.

Not automatically.

If you use a bar, consider its protein amount, carbohydrate and when you will next eat a meal.

Check the ingredients and any ‘may contain’ statement on the current pack for the substances that matter to you. Varieties discussed here include peanut, soya and milk ingredients or nut warnings; vegan or gluten-free wording does not settle a separate allergen question.
Use the current pack for the flavour and serving size you are buying. Recipes and product information can change, so recheck protein, sugars and ingredients when a particular figure or allergen matters to your decision.
