Who is comparing these bars?

Organic-first shoppers

If certified organic ingredients matter to you, check that claim on the pack alongside energy per bar and the rest of its nutrition information. Organic labelling is not a measure of portion size.

People comparing between-meal snacks

If you are considering a protein bar instead of another snack, compare the portion you would actually eat. A conventional bar’s protein and sugar figures may suit your criteria without meeting an organic-sourcing preference.

Shoppers checking ingredients closely

Allergens, precautionary statements and sweeteners can change which bar is suitable. Check the current pack for the particular flavour, even if you know another product from the same brand.

What should you check before buying?

Start with the serving size and nutrition panel, then check organic labelling and ingredients. NHS food-labelling guidance explains the nutrition information on pre-packed food; GOV.UK’s UK organic-labelling guidance, dated 20 August 2025, addresses organic claims separately.

Organic-labelled, plant-based bar

Consider it when: Certified organic sourcing and a plant-based ingredient list are priorities.

Check separately: Organic labelling does not tell you the energy or sugars in the portion you will eat.

Conventional protein bar

Consider it when: Declared protein and sugars per bar matter more to you than organic sourcing.

Check separately: Ingredients, allergens and sweeteners vary by product; some bars carry excessive-consumption warnings.

PriorityWhat to checkYour needs
Portion and energy Compare kcal per bar and per 100g. Check whether the stated serving is the amount you intend to eat. I want to account for the whole bar as a snack, rather than judge it by a front-of-pack protein claim.
Organic labelling Check the pack’s organic claim and certification information. GOV.UK’s UK guidance says organic-labelled food must meet organic production rules, contain at least 95% organic agricultural ingredients and be certified by an approved organic control body. Certified organic sourcing matters to me; a plant-based or natural-sounding description alone does not answer that question.
Nutrition balance Read protein, total sugars, saturates and salt alongside energy. Compare per-bar figures as well as per-100g values when bar sizes differ. A protein figure catches my eye, but I also want to know what else is in the portion.
Ingredients and warnings Read the full ingredients, highlighted allergens, any “may contain” statement and sweetener or polyol warnings on the current flavour’s pack. I need to avoid an ingredient or check whether a sweetened bar suits my preferences before choosing a flavour.

What is easy to overlook?

  • Assuming organic means fewer kcal

    Organic certification concerns production and labelling, not the energy in a bar. NHS weight-management guidance also emphasises what and how much you eat.

    Use organic status to assess sourcing, then compare kcal and other nutrition values for the portion you would eat.

  • Comparing only protein or sugar claims

    Bars can have different serving sizes, so a front-of-pack figure may not give you a like-for-like comparison.

    Read the per-bar and per-100g nutrition figures, including energy, sugars, saturates and salt.

  • Overlooking flavour-specific allergens

    The BodyMe recipes described by the brand include cashews, while the reviewed Barebells Salty Peanut bar declares milk, peanuts and soya. Ingredients and precautionary statements need checking for the product you choose.

    Read the current pack’s ingredients, highlighted allergens and “may contain” statement for that flavour.

  • Ignoring sweetener warnings

    Barebells and Grenade warn that excessive consumption of their reviewed bars may have a laxative effect. A low declared sugar figure does not replace a check of the ingredients and warnings.

    If sweeteners or polyols affect your choice, read the formulation and pack warning before buying.

Relevant brand examples

These examples show different product approaches; a brand mention does not establish the organic status or nutrition of every flavour.

BodyMe

BodyMe describes its vegan protein bars as made with organic ingredients and containing 16g plant protein.

  • Its stated organic and plant-based approach is relevant if ingredient sourcing is your priority.
  • Check the chosen flavour’s certification information, nutrition panel and allergens on the pack; the recipes described by BodyMe include cashews.

Hammer Nutrition

Hammer Nutrition UK describes an organic vegan bar containing 14g plant protein.

  • Its declared organic pea-protein formulation offers another plant-based option to examine.
  • Its active-use positioning does not establish how its energy per bar compares with another snack; check the chosen pack’s nutrition and certification information.

Grenade

Grenade’s reviewed Chocolate Chip Salted Caramel bar is described by the brand as containing 20g protein and 1.4g sugars.

  • The declared protein and sugar figures give shoppers two values to compare for that specific bar.
  • The reviewed product carries a polyol-related excessive-consumption warning; check allergens and the details of any other flavour separately.

PhD

PhD lists 250 kcal and 21g protein per 64g bar for its Smart Protein Bar Choc Brownie flavour.

  • Flavour-specific per-bar figures allow a portion comparison.
  • The manufacturer warns that excessive consumption may cause laxative effects; do not apply the Choc Brownie figures to other flavours.

Barebells

Barebells declares 204 kcal and 20g protein per 55g Salty Peanut bar.

  • The stated portion size and nutrition figures help with comparisons between bars.
  • Salty Peanut declares milk, peanuts and soya, gives precautionary allergen information and carries an excessive-consumption laxative warning.

Joybuy protein bar options

These conventional protein bar options can be compared with an organic-labelled bar. Check each pack’s portion, nutrition, ingredients and organic labelling against the criteria that matter to you.

Grenade Oreo Flavour protein bars, four 60g bars

Grenade Oreo Flavour Protein Bars, 4 × 60g

For a portion comparison, check the nutrition for one 60g bar rather than the four-bar pack. Read the current pack’s ingredients and allergens before choosing it in place of an organic-labelled option.

Joybuy
Grenade Soft Core Double Chocolate protein bars, twelve 50g bars

Grenade Soft Core Double Chocolate Bars, 12 × 50g

If you are comparing snack portions, use the nutrition values for each 50g bar. Check the Double Chocolate pack’s ingredients, allergens and sweetener information rather than assuming they match another Grenade flavour.

Joybuy
Nature Valley Protein Peanut and Chocolate bars, four 40g bars

Nature Valley Protein Peanut & Chocolate Bars, 4 × 40g

For a like-for-like snack comparison, read the values for each 40g bar as well as per 100g. Check the current pack’s allergen information and any organic claim before deciding whether it meets your requirements.

Common questions

Does organic mean a protein bar has fewer kcal?

No. Organic labelling concerns how a food is produced and labelled, not its energy or portion size. Compare kcal per bar and per 100g, then read the other nutrition values for the portion you intend to eat.

How do I check an organic claim on a UK protein bar?

Check the pack’s organic claim and certification information. GOV.UK’s UK organic-labelling guidance, dated 20 August 2025, says organic-labelled food must meet organic production rules, contain at least 95% organic agricultural ingredients and be certified by an approved organic control body.

Should I pick the bar with the most protein?

Not on that figure alone. Compare protein alongside kcal, sugars, saturates and salt for the actual bar you would eat, and check how that snack fits into what and how much you eat overall.

Is “no added sugar” enough information to choose a bar?

No. Read total sugars and energy on the nutrition panel, plus the ingredients and any sweetener warnings. The reviewed Grenade and Barebells products carry warnings about laxative effects from excessive consumption.

What should I check if I have a food allergy?

Read the current pack’s ingredients, highlighted allergens and any “may contain” statement for the exact flavour. The Food Standards Agency explains that precautionary allergen labelling communicates possible unintended allergen presence; it is different from an allergen listed as an ingredient.
