What should you check before choosing?
Check the exact product’s gluten-free information first; pack size, protein per bar and other allergens then help narrow the choice.

What to check |
Your needs |
| Gluten-free status |
Find a current gluten-free statement for the exact flavour and pack. Read the ingredients and allergen information rather than applying a claim from another product in the range. |
I want to recognise the gluten-free information on the bar I am actually buying. Of 3,785 respondents to Coeliac UK’s 2025 Shopping Habits survey, 74.7% said they trusted its Crossed Grain Trademark more than a gluten-free statement; that measures trust, not protein-bar purchases. |
| Pack size and portability |
Compare the number of bars and their individual sizes: Tesco lists KIND Dark Chocolate Nut as 24 x 50g and Nature Valley Peanut & Chocolate as 4 x 40g. Check wrapping and storage instructions on the pack you choose. |
For snacks to keep at home or take out, I need a pack count I can use. In the same Coeliac UK survey, 70% of the 3,785 respondents were dissatisfied with the quality of on-the-go gluten-free products; the question was not about protein bars specifically. |
| Protein per bar |
Compare like-for-like figures for one bar, not the total across a box. Tesco lists 12g per KIND Dark Chocolate Nut bar and 10g per Nature Valley Peanut & Chocolate bar. |
A smaller pack may be enough for me to try a bar, while a larger one may suit repeated sharing. I can compare the protein in each bar without assuming the larger box changes its per-bar amount. |
| Other allergens |
Check the declared ingredients and precautionary allergen wording for every intended recipient. KIND’s listed pack contains mixed nuts and soya; the Nature Valley Peanut & Chocolate listing identifies peanuts, soya and milk and says it may contain nuts. |
Gluten-free alone does not settle whether I can share these bars with everyone in the household. Another person’s nut, milk or soya requirements could rule out a pack. |
Which brand ranges need a closer look?
These examples describe specific products or ranges; check the exact bar rather than assuming one brand-wide gluten-free status.
KIND
Tesco lists KIND Protein Dark Chocolate Nut as a gluten-free 24 x 50g multipack, a format to consider when several people will use the bars.
- Tesco states 12g protein per bar for this product.
- The listed product contains mixed nuts and soya and is sold through Tesco Marketplace by a third-party seller.
Nature Valley
Nature Valley Protein Peanut & Chocolate appears in gluten-free 4 x 40g and 8 x 40g listings, giving shoppers two pack counts to check.
- Tesco lists 10g protein per bar for the 4-pack; Joybuy’s 8-pack description also states 10g per bar.
- The Peanut & Chocolate product lists peanuts, soya and milk, and its 4-pack listing says it may contain nuts.
PhD
PhD lists a Smart Protein Bar 12-pack; its Choc Brownie variant is listed with 21g protein per 64g bar.
- The stated pack count and per-bar protein figure make it possible to compare this variant’s format with other bars.
- Check the current gluten-free status of the exact variant before considering it for coeliac shopping.
Myprotein
Myprotein UK describes gluten-free choices within its wider protein-bar range.
- The range offers a starting point for looking at different dietary options.
- A range-level description does not establish the gluten status, ingredients or pack count of an individual multipack; check its own label.
Barebells
Barebells sells several bar formats and flavours, so the name alone is not a gluten-free selection rule.
- Barebells states that its Vegan Caramel Choco Chip, Vegan Fudge Brownie and Vegan Caramel Peanut bars contain wheat protein and gluten.
- Check any other Barebells flavour and pack individually rather than assuming it has the same ingredients or gluten status.

Questions about gluten-free protein bars
Can I choose a protein bar just because its brand sells gluten-free products?
No. Check the gluten-free statement for the exact flavour and pack you intend to buy, along with its current ingredients and allergen information. A claim about a wider range does not identify which individual bars carry it.
Do I need to read the allergens if a bar says gluten free?
Yes. A gluten-free statement does not address other allergens. The listed KIND Dark Chocolate Nut pack contains mixed nuts and soya, while Nature Valley Peanut & Chocolate identifies peanuts, soya and milk and says it may contain nuts.
Should I choose the KIND 24-pack or the Nature Valley 4-pack for sharing?
Choose by the number of bars your group will use and by everyone’s allergen requirements. Tesco lists the gluten-free KIND Dark Chocolate Nut pack as 24 x 50g with 12g protein per bar; its gluten-free Nature Valley Peanut & Chocolate pack is 4 x 40g with 10g per bar. Neither suits someone who needs to avoid its declared allergens.
Does a higher protein figure mean a bar is gluten free?
No. Protein per bar and gluten status are separate checks. PhD lists 21g protein per 64g bar for its Smart Protein Bar Choc Brownie variant, but check the exact pack’s current gluten-free information before considering it for coeliac shopping; Barebells explicitly says several of its vegan bars contain wheat protein and gluten.
How should I keep a multipack after opening it?
Follow the storage instructions for the product you buy and keep individual bars in their wrappers where the pack directs you to do so. The Nature Valley Peanut & Chocolate listing says to store the pack in a cool, dry place away from direct sunlight and to keep the bars wrapped after opening.
