Who needs to check what?
The relevant check depends on your allergen and on any sweeteners or warnings that matter to you.
Shoppers managing a food allergy
Compare the current pack’s ingredients and allergen information with your specific allergen. GOV.UK says food businesses must identify any of 14 regulated allergens used as ingredients; the words “sugar free” do not answer that allergy question.
Shoppers checking polyol sweeteners
Compare the named sweeteners and pack warnings, particularly if you expect to use mints frequently. Sainsbury’s lists an excessive-consumption laxative-effect warning for Smint XXL Spearmint, and Marks & Spencer gives a similar warning for its Sugar-Free Clear Mint Drops.
Shoppers avoiding aspartame or phenylalanine sources
Check the exact formula rather than assuming sugar-free mints use the same sweeteners. Sainsbury’s lists aspartame and a phenylalanine warning for Smint XXL Spearmint; Marks & Spencer lists sorbitol and steviol glycosides for its Sugar Free Curiously Strong Mints.
What matters when choosing?
Start with the allergen check on the current pack, then narrow the choice by sweetener formula and exact product variant.

What to check |
Your needs |
| Allergen information |
Read the current ingredients and allergen information for your specific allergen. Apply a free-from claim only to what it names. |
I need to know whether this particular pack is suitable for my allergy; “sugar free” or a claim about a different allergen is not enough. |
| Sweetener formula |
Compare the listed sweeteners and any consumption warning. Sainsbury’s lists a laxative-effect warning for excessive consumption of Smint XXL Spearmint. |
If I use mints regularly, I want to know which sweeteners are in the pack and what its warning says. |
| Aspartame information |
Look for aspartame and a phenylalanine warning where relevant. Compare the current formula of the exact variant. |
Avoiding aspartame matters to me, so I cannot treat every sugar-free mint as interchangeable. |
| Sugar-free variant |
Match the full product name to its ingredients and sugar declaration. Tesco lists sugar and glucose syrup in standard Trebor Extra Strong Peppermint; Trebor Mighties is a separate sugar-free product. |
I want the sugar-free variant, not another mint from a familiar brand with a similar flavour or name. |
Brand and product-line references
These examples show why the exact mint and its current pack matter more than a brand name alone.
POLO
Tesco lists POLO Sugar Free as a pressed mint with sorbitol, magnesium stearate and mint oils.
- The retailer-listed ingredients offer a concise formula to compare with the current pack.
- A short ingredient list is not an allergen-free claim; Tesco advises checking the pack because product information can change.
Smint
Sainsbury’s lists the specific Smint XXL Spearmint product as gluten free and suitable for nut allergy sufferers.
- Those retailer-listed claims address gluten and nut-related shopping questions for that product.
- They do not cover other allergens. The listing also carries a phenylalanine warning and an excessive-consumption laxative-effect warning.
M&S
Marks & Spencer lists different sweetener formulas across its sugar-free mint products.
- Its Sugar Free Curiously Strong Mints list sorbitol and steviol glycosides; Clear Mint Drops list isomalt and sucralose.
- Clear Mint Drops carry an excessive-consumption warning. Check the current pack’s ingredients and allergen information for either product.
Trebor
Tesco lists both a standard Extra Strong Peppermint roll and the separate sugar-free Mighties variant.
- The Mighties listing names sorbitol and sucralose, allowing a comparison with other sugar-free formulas.
- The standard Extra Strong Peppermint roll contains sugar and glucose syrup. Check the exact variant and current availability before choosing.

Smint Sugarfree Spearmint XXL Tin

The listed formula contains sorbitol and aspartame and carries a phenylalanine warning and an excessive-consumption laxative-effect warning.

Frequently asked questions
Does “sugar free” mean a mint is suitable for a food allergy?
No. “Sugar free” concerns sugar content, not the absence of your allergen. GOV.UK says regulated allergens used as ingredients must be identified for prepacked food; compare the current pack’s ingredients and allergen information with your specific allergy.
Does a gluten-free or nut-specific claim cover other allergies?
No. Sainsbury’s lists Smint XXL Spearmint as gluten free and suitable for nut allergy sufferers, but those claims do not establish suitability for an allergy to milk, soya, sesame or another allergen. Check the full current pack for your own allergen.
Why check the pack if a retailer lists the ingredients online?
Ingredients and allergen information can change. Tesco advises shoppers to read the product label rather than rely only on its website, so use an online listing to narrow your choices and the current pack for the final check.
Which sweetener warnings should I look for?
Check the warning on the exact product. Sainsbury’s lists a phenylalanine warning and an excessive-consumption laxative-effect warning for Smint XXL Spearmint; Marks & Spencer lists an excessive-consumption laxative-effect warning for its Sugar-Free Clear Mint Drops.
