Shoppers looking for protein in their snack
A salted-caramel protein bar is worth comparing if you want a stated amount of protein per bar. Its flavour does not make it traditional toffee, so check the product type as well as the nutrition panel.
Who is each option for?
Shoppers wanting a small sweet
A single toffee stick suits someone choosing confectionery after exercise without expecting it to provide the protein listed on a protein bar. Tesco’s Werther’s Original Stick is a 50g example.
Shoppers seeking a vegan, gluten-free caramel flavour
Waitrose lists a 50g TREK salted-caramel flapjack labelled vegan and gluten-free. Check its current allergen statements too: the product information identifies soya and warns of possible milk, nut and peanut contact.
What should you check?
Decide whether you want a sweet treat or a bar with stated protein, then compare the portion you would actually eat.
| Priority | What to check | Your needs |
|---|---|---|
| Snack purpose | Compare protein per bar, not just a toffee or caramel flavour. Marks & Spencer lists 20g in its 55g salted-caramel bar; Tesco lists 0.3g per 100g for Werther’s Original Stick. | I want to know whether I am choosing a sweet or a bar that contributes a stated amount of protein. |
| Sugars and portion | Check whether the figure is per 100g or per bar, and look at the pack size. Tesco lists 71.6g sugars per 100g for Werther’s Original Stick; Waitrose lists 1.1g per 40g FULFIL bar. Total sugars on a label are not necessarily the same as free sugars, as NHS guidance explains. | For a single snack, I want to compare the amount I would eat rather than mistake a per-100g figure for a serving figure. |
| Ingredients and warnings | Read the current pack for allergens and precautionary statements. The M&S and FULFIL bars carry warnings about laxative effects from excessive consumption; the TREK flapjack is labelled vegan and gluten-free but has additional allergen statements. | Milk, soya, nuts, peanuts, wheat or sweetener warnings could affect which bar I can choose. |
| Training schedule | Consider when your next session is and what else you will eat and drink. The British Dietetic Association advises starting with carbohydrate-rich food and fluids promptly after exercise when quick refuelling is required; needs vary with training demands. | If I have another demanding session soon, I need to think about refuelling beyond the flavour or protein figure on one bar. |
| Pack format | Distinguish one portion from one retail pack. The Joybuy options below are four- or twelve-bar packs, even though their titles give a weight for each bar. | I may want one bar to take with me, but I also need to know how many bars I am buying. |
Common buying mistakes
-
Expecting a toffee stick to do the same job as a protein bar
Tesco lists 0.3g protein per 100g for Werther’s Original Stick. Its single-stick format does not give it the protein content stated for the compared salted-caramel protein bars.
Choose the type of snack first, then compare protein using each product’s actual bar size.
-
Assuming a protein or sugar claim settles allergen suitability
The M&S and FULFIL bars have allergen limitations and warnings about excessive consumption. A nutrition figure does not replace the ingredients and allergen information.
Read the current physical pack before eating, particularly if milk, soya, nuts, peanuts, wheat or sweeteners affect your choice.
-
Treating total sugars as an exact free-sugars figure
As NHS guidance explains, a label’s total-sugars figure can include naturally occurring sugars as well as sugars relevant to free-sugar guidance.
Use the ingredients list, product type and portion size alongside the nutrition panel; do not convert total sugars directly into a free-sugars figure.
-
Applying school-food rules to a personal purchase
Government guidance distinguishes restrictions on certain retail promotions and placements from requirements for food provided in state-funded schools in England. Those rules do not, by themselves, determine whether an individual can buy a snack.
Use the product’s own ingredients, nutrition information and pack size to assess this personal purchase, rather than its shelf position or a school-food rule.

Questions about post-gym snacks
Can a toffee stick take the place of a protein bar after the gym?
Not if you specifically want the snack to contribute the stated protein offered by a protein bar. Tesco lists 0.3g protein per 100g for its 50g Werther’s Original Stick, making it a different choice from the salted-caramel protein bars. The British Dietetic Association advises prompt carbohydrate-rich food and fluids when quick refuelling is required, but individual needs depend on training demands.
How do the stated protein amounts compare?
Marks & Spencer lists 20g protein in its 55g salted-caramel bar, while Waitrose lists 14g in a 40g FULFIL bar. These are amounts for different bar sizes, so compare the stated portion as well as the protein figure; neither figure alone establishes how a bar will suit your whole post-exercise meal plan.
Are salted-caramel protein bars suitable for everyone with allergies?
No single allergen statement covers all of them. The M&S bar is marked unsuitable for several specified allergy groups and for coeliacs; the FULFIL product information identifies milk, soya, peanut and hazelnut ingredients. TREK is labelled vegan and gluten-free but contains soya and carries precautionary allergen statements. Check the current pack for the particular bar you intend to eat.
Do HFSS rules prevent me from buying toffee?
The Department of Health and Social Care’s guidance describes restrictions on certain promotions and placements of qualifying high-fat, salt or sugar products by affected retailers selling to England, including online equivalents; it does not set out a general ban on an individual purchase. Do not assume every toffee product has the same classification or apply England’s retail rules across the whole UK.
Do school-food rules determine what I can buy after the gym?
No. The Department for Education’s school-food guidance concerns food and drink provided in state-funded schools in England, not an adult’s personal snack purchase. Its September 2026 guidance says proposed changes for September 2027 remain subject to Parliamentary approval.
