Who is this for?

Weekly grocery shoppers

If you are buying bars for work, travel or between-meal snacks, choose a pack quantity you expect to use and compare the nutrition per whole bar. The Grenade, PhD and Myprotein examples listed by Tesco contain 20–21g protein per bar, with energy values from 222 to 245kcal.

Shoppers comparing nutrition labels

If listed sugars matter to you, read energy and saturated fat alongside them. The cited Tesco bars show why a sugar figure alone does not describe the whole bar.

Shoppers checking ingredients

If you need to avoid particular allergens or want a plant-based variant, check the exact flavour’s ingredients and precautionary statements. Barebells offers vegan variants, but says its Vegan Caramel Peanut bar contains wheat protein.

What should you compare?

Start with the serving shown on the wrapper, then check the recipe and whether the pack quantity suits your weekly shop.

PriorityWhat to checkYour needs
Protein per bar Compare grams per whole bar and note its weight. Check the exact flavour rather than relying on a front-of-pack description. I want to know what one bar provides, especially when choosing between different serving sizes.
Whole nutrition panel Read energy, sugars, saturated fat and salt per bar. Use per-100g figures for a comparison between bars of different weights; the NHS explains both label formats. Sugars matter to me, but I also want to see the other values for a bar I may buy regularly.
Ingredients and allergens Check the exact flavour’s ingredients, allergen declaration, precautionary statements and information about sweeteners or polyols. Before choosing a flavour, I need to know whether its recipe meets my ingredient requirements.
Pack quantity and availability Check the number and size of bars, the best-before date and availability for your store or delivery area before ordering. A single bar lets me try a flavour; a multipack makes more sense once I know I will use it.

What can catch you out?

  • Choosing by protein grams alone

    Tesco’s cited Grenade, PhD and Myprotein bars contain 20–21g protein per bar, while their energy values range from 222 to 245kcal. Their other nutrition values and ingredients also differ.

    Compare the flavours you would actually buy on a per-bar basis, including sugars, saturated fat and salt.

  • Overlooking polyols and sweeteners

    Tesco lists 18g polyols in the cited Grenade bar. Its PhD listing and Myprotein’s product guidance warn that excessive consumption may have a laxative effect.

    Read the ingredients and any pack warning before committing to a multipack of an unfamiliar bar.

  • Assuming every flavour has the same ingredients

    Recipes differ. Barebells says its Vegan Caramel Peanut bar contains wheat protein, while the cited Tesco bars have different ingredient and precautionary allergen statements.

    Check the label of the exact flavour, including when you have bought another variant from the same range before.

  • Planning around a listing without checking the order

    A product listing or offer does not establish what is available for your delivery area or local store when you place your weekly order.

    Confirm availability, pack quantity and best-before date before adding several bars to the shop.

Which brands might you encounter?

Grenade

Tesco lists Carb Killa Chocolate Chip Salted Caramel as an individual 60g bar.

  • Tesco lists 21g protein and 2g sugars per 64g Chocolate Peanut Butter bar.
  • That Tesco listing also gives 245kcal per bar and warns about excessive consumption. Check the chosen flavour’s ingredients and availability.

  • Tesco’s White Gold listing gives 20g protein and 7.9g fibre per 60g bar.
  • The White Gold recipe lists milk, soy and wheat-containing ingredients. Myprotein says nutrition can vary by flavour.

Common questions

How can I compare protein bars during a weekly shop?

Compare nutrition per whole bar first, then use per-100g figures to compare bars of different sizes. The NHS explains that prepacked-food labels show energy, fat, saturated fat, carbohydrate, sugars, protein and salt; check ingredients and allergens for the exact flavour too.

Does a lower sugar figure settle the choice?

No. Read energy, saturated fat, salt and the ingredients alongside sugars. Tesco’s cited Grenade, PhD and Myprotein bars contain 20–21g protein per bar, but their energy values and recipes differ.

What should I check if I need to avoid an allergen?

Read the ingredient and allergen information for the exact bar and flavour, including precautionary statements. UK Food Standards Agency guidance identifies allergens that food businesses must declare when present as ingredients; the cited bars have differing recipes.

Is a protein bar necessarily a meal replacement?

No: protein content alone does not establish that role. The cited PhD and Myprotein ranges are described as snacks, so compare the whole nutrition panel with what you want for that eating occasion.

Can I use an online grocery listing to check a bar’s recipe?

Use the listing to compare options, then read the wrapper before consuming the bar. Tesco advises shoppers to check product labels because food products can be reformulated.
