For a summer picnic, choose a protein bar by its protein per bar, ingredients and storage instructions rather than its front-of-pack description alone. Myprotein UK lists 30g protein for its High-Protein Bar if that serving size suits your snack; if vegan suitability matters, PhD describes Smart Plant as vegan, but you should still check the exact flavour’s ingredients and allergens.
If you want a bar that needs no preparation, compare protein per bar with the bar’s size, energy and carbohydrate on the exact flavour’s nutrition panel. Myprotein UK lists 30g protein and 23g carbohydrate for its High-Protein Bar; Tesco Groceries lists 21g protein for the reviewed 60g Grenade Carb Killa flavour.
Check the stated suitability and protein sources, not just the product name. PhD describes its Smart Plant range as suitable for vegans and vegetarians, while the reviewed Myprotein High-Protein Bar contains milk protein and collagen.
Ask about dietary requirements before choosing flavours, and keep the wrappers available so guests can check ingredients, allergen statements, sweeteners and any age guidance for themselves.
Start with the serving you intend to pack, then check dietary suitability and how the bars will be stored alongside the rest of the picnic food.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per bar | Compare grams of protein and the weight of one bar on the exact flavour’s label. Check energy and carbohydrate for the same serving rather than comparing pack descriptions alone. | I want to know what one bar provides as a picnic snack. Myprotein UK lists 30g protein and 23g carbohydrate for its High-Protein Bar; Tesco Groceries lists 21g protein for the reviewed 60g Grenade Carb Killa flavour. |
| Diet and allergens | Read the dietary-suitability statement, ingredients and may-contain information on each flavour. Check for milk, soya, peanuts, nuts and gluten-containing cereals where relevant. | For a vegan guest, I would check a plant-based range such as PhD Smart Plant, which PhD describes as vegan, and then read the chosen wrapper for allergens. |
| Sugars and sweeteners | Compare sugars per bar with the ingredients, polyols and any on-pack warning. Tesco Groceries lists 1.3g sugars and 18g polyols for its reviewed 60g Grenade Carb Killa flavour. | A lower sugar figure matters to me, but I also want to know which sweeteners and polyols are in the bar before choosing it. |
| Picnic storage | Follow the bar’s storage directions and keep it shaded and dry. Manage foods normally kept in the fridge separately: GOV.UK says they also need to be kept cool at a picnic. | I need a bar I can pack according to its label without treating it as a replacement for keeping chilled picnic food cool. |
Bars can have different serving weights and nutrition profiles. Myprotein UK lists 30g protein for its High-Protein Bar, while Tesco Groceries lists 21g for the reviewed 60g Grenade Carb Killa flavour.
Compare the exact flavour’s protein, energy, carbohydrate and serving size before deciding which bar fits your planned snack.
A small sugars figure does not describe every carbohydrate ingredient. Tesco Groceries lists 18g polyols in the reviewed Grenade Carb Killa bar.
Read the ingredients, carbohydrate breakdown and any warning on the wrapper, particularly if polyols affect your choice.
Bars with directions for cool, dry storage should be packed accordingly. Foods normally refrigerated need different handling: GOV.UK says to keep them cool at a picnic and advises trying not to leave food out for longer than two hours when temperatures are higher than usual.
Keep bars shaded and dry, and use a cool bag with ice or frozen gel packs for picnic foods that normally need refrigeration.
Ingredients and precautionary allergen statements differ between the reviewed bars. The Tesco Groceries listing for the reviewed Grenade Carb Killa flavour also gives a lower age limit of 14 years.
Ask guests about dietary requirements, check the precise products you buy and keep their wrappers available at the picnic.
These examples illustrate different label and ingredient checks; a brand name alone does not establish that every flavour has the same nutrition or dietary suitability.

No: check the grams of protein and the serving size on the exact bar’s nutrition panel. Compare energy, carbohydrate and ingredients for that same serving if they also matter to your picnic snack choice.
Follow each bar’s storage directions and keep bars that specify cool, dry storage out of direct sunlight. Separately, GOV.UK says foods you would normally keep in the fridge also need to be kept cool at a picnic; it advises trying not to leave food out for longer than two hours when temperatures are higher than usual.
Check the sweeteners, polyols and any warning on the exact wrapper. For example, Tesco Groceries lists 1.3g sugars alongside 18g polyols in its reviewed 60g Grenade Carb Killa flavour, so the sugars figure does not describe the whole ingredient profile.
No: check the precise flavour’s suitability statement, ingredients and precautionary allergen information. PhD describes Smart Plant as vegan, while the reviewed Myprotein High-Protein Bar contains milk protein and collagen; neither a range name nor a dietary label replaces an allergen check for the person eating the bar.
