For a longer journey, a sugar-free roll or multipack gives you more mints to carry; for a short trip or a crowded pocket, compare the smaller packs. If you prefer a tin or a particular sweetener, choose by the exact product label: sugar-free mints can contain sweeteners and provide energy, and some carry excessive-consumption warnings.
If you want a small, ready-to-eat sweet for the journey, start with the space in your pocket or bag and how many mints you intend to carry. Sainsbury's lists a 12.5g Trebor pack, while Tesco lists a 33.4g Polo roll.
Read the sugars and energy figures together, using the serving size shown on the pack. Tesco lists 10 kcal and less than 0.5g sugars per three Polo Sugar Free mints; the sugar-free description alone does not tell you the energy per serving.
Check the exact formulation rather than treating sugar-free mints as interchangeable. Retailer listings identify sorbitol in Polo, xylitol in Peppersmith Peppermint and several sweeteners, including aspartame, in Smint XXL. Check dietary declarations and warnings on the product you choose.
Decide how much you want to carry, then compare the nutrition panel, ingredients and warnings on the exact pack.
| Priority | What to check | Your needs |
|---|---|---|
| Pack size | Compare pack weight and container format. Retailer listings show 12.5g Trebor and 18g M&S packs, a 33.4g Polo roll and a 4 × 33.4g Polo multipack. | For a brief journey, I may want a smaller pack in my pocket. For several travel days, I may prefer to bring more mints. |
| Sugars and energy | Read both figures on the same per-serving or per-100g basis. Tesco lists 10 kcal and less than 0.5g sugars per three Polo Sugar Free mints. | I want to know what a serving contains, particularly if I expect to have mints more than once during the trip. |
| Sweeteners and dietary details | Read the ingredient list and any vegan or gluten-free declaration. Tesco identifies sorbitol in Polo; Waitrose identifies xylitol in Peppersmith Peppermint and several sweeteners in Smint XXL. | If I avoid a particular ingredient or need a dietary declaration, the words “sugar free” are not enough to make my choice. |
| Pack warnings | Check excessive-consumption and phenylalanine wording where relevant. Waitrose lists an excessive-consumption warning for Polo and both warnings for Smint XXL. | On a long journey, I want to read the warnings before packing a large quantity or offering mints to someone else. |
| Flavour | Check the flavour description separately from pack size. Sainsbury's calls Trebor Mighties extra-strong peppermint; M&S describes its Curiously Strong mints as extra strong. | I may prefer a stronger peppermint description, but I still need to check the ingredients and quantity independently. |
Sugar-free describes sugar content, not energy content. Tesco lists 10 kcal per three-mint serving of Polo Sugar Free.
Compare energy and sugars using the serving size printed on the pack, especially if you expect to eat mints repeatedly.
Waitrose lists excessive-consumption warnings for Polo Sugar Free and Smint XXL. GOV.UK says UK food containing more than 10% polyols must carry a laxative-effect warning.
Read the wording on the exact pack and take account of it when deciding how many mints to carry and eat during the journey.
Retailer ingredient listings identify sorbitol in Polo, xylitol in Peppersmith Peppermint and a mixture including aspartame in Smint XXL.
Check the ingredients and dietary declarations if a particular sweetener or product suitability matters to you.
“Extra strong” describes the peppermint flavour in the Trebor and M&S retailer listings; it does not state a duration.
Choose that flavour description if it appeals to you, then compare pack size, ingredients and warnings separately.
These retailer-listed products illustrate different pack formats and formulations; a brand name alone does not establish the details of every variant.

For a train journey, compare this 35g peppermint pack with the space you have available. Check the exact pack's sweetener ingredients before choosing it for an ingredient preference, and keep mints away from young children where the packaging warns of a choking risk.

The 22g grape-flavoured pack is an option to compare when you want to carry a smaller quantity. Read the exact pack for its sweeteners and its sugars and energy figures if those details affect your choice.
Not necessarily. Tesco lists 10 kcal and less than 0.5g sugars per three Polo Sugar Free mints. Compare both the energy and sugars figures on the serving basis shown on your pack.
Read the ingredient list on the exact product. Retailer listings identify sorbitol in Polo, xylitol in Peppersmith Peppermint and sorbitol, aspartame, sucralose and acesulfame K in Smint XXL. GOV.UK also sets out UK labelling wording for foods containing sweeteners.
GOV.UK says UK foods containing more than 10% polyols must carry a warning that excessive consumption may cause a laxative effect. Waitrose lists excessive-consumption warnings on Polo Sugar Free and Smint XXL, so read the warning before using a large pack throughout a journey.
Check the age and choking warnings on the exact pack before offering mints to a child. Waitrose's Polo Sugar Free listing warns that children under four have limited chewing ability and could choke on small sweets; that wording should not be assumed to apply to every product.
