What should you compare?
Start with whichever requirement would rule a bar out, then compare nutrition values and ingredients on the same serving basis.
| Priority | What to check | Your needs |
| Organic status |
Look for an organic claim for the exact bar and check its certification presentation. The Department for Environment, Food & Rural Affairs says products and suppliers must be certified by an approved control body; food labelled organic must contain at least 95% organic agricultural ingredients. |
I want organic production to be part of this snack choice, not just plant-based or natural-sounding wording. |
| Protein per bar |
Compare the stated grams of protein and the bar’s weight. BodyMe states 16g per bar for its organic vegan range; Grenade states 20g per 60g Salted Caramel bar, and PhD lists 21g per 64g Choc Brownie Smart Bar. |
The amount in the portion I would actually eat matters more to me than a general protein claim on the wrapper. |
| Nutrition panel |
Compare energy, sugars, saturates and salt per 100g, then check the values for one bar. NHS food-label guidance identifies these alongside protein on prepacked-food nutrition labels. |
I want to see how the whole bar fits my afternoon snack choice, rather than judging it by protein alone. |
| Ingredients and allergens |
Read the exact flavour’s ingredients, emphasised allergens, precautionary statements and any polyol warning. The Food Standards Agency says allergens present in prepacked food must be emphasised in its ingredients list. |
I need to check the ingredients I avoid, including when I switch flavours or buy a mixed pack. |

Common questions
What makes a protein bar organic in the UK?
Food marketed as organic must meet organic production and certification requirements. The Department for Environment, Food & Rural Affairs says the product and suppliers must be certified by an approved control body, and food labelled organic must contain at least 95% organic agricultural ingredients. Check the claim for the particular bar.
Does organic mean lower sugar or fewer calories?
No: organic labelling does not establish a bar’s sugar or energy values. Compare the nutrition information per 100g and per bar, including sugars, saturates and salt, whether the product is organic-labelled or conventional.
Can I choose an afternoon bar by protein content alone?
Protein per bar is useful if that is your priority, but it does not answer questions about portion size, other nutrition values, allergens or organic status. Compare the whole nutrition panel and ingredient list for the bars you are considering.
How should I check a protein bar for allergens?
Read the ingredient list and precautionary allergen statement for the exact flavour. For example, Grenade’s cited Salted Caramel bar lists milk and soy and says it may contain gluten, peanuts and nuts; that information should not be assumed to describe every Grenade bar.
Why do some bars carry a laxative-effect warning?
The cited Grenade bar carries a polyol-related warning about excessive consumption, and PhD gives an excessive-consumption warning for Smart Bar. If this affects your choice, check the ingredients and warning on the particular flavour before buying a multipack.
