Choose sugar-free mints for a mint before or after a 5k, not as planned run fuel. Tesco lists three Polo Sugar Free Mints at 10 kcal and less than 0.5 g sugars, while the British Dietetic Association identifies carbohydrate as the main fuel for exercising muscles. Whether you need food around a run depends on the activity and your circumstances; sugar-free mints should not replace fast-acting carbohydrate needed for a hypo.
A sugar-free mint may suit someone who wants one before or after a 5k. Tesco lists three Polo Sugar Free Mints at 10 kcal; the British Dietetic Association identifies carbohydrate as the main fuel for exercising muscles.
Someone following a diabetes plan for exercise needs to keep hypo treatment distinct from sugar-free confectionery. The NHS lists glucose tablets, glucose gel and sugary drinks among options that raise blood glucose quickly.
Mint formulations differ. Retailer listings for Polo, Trebor and Sulá include sorbitol or isomalt, while GOV.UK states that foods containing more than 10% polyols must carry an excessive-consumption laxative-effect warning.
Decide whether you want a mint or food for exercise, then check the serving information, ingredients and warnings on the pack you intend to carry.
| Priority | What to check | Your needs |
|---|---|---|
| Purpose and serving | Check energy and carbohydrate per serving, not just per 100 g. Tesco lists three Polo Sugar Free Mints at 10 kcal and less than 0.5 g sugars; the British Dietetic Association identifies carbohydrate as exercise fuel. | I want a mint before or after my run, rather than something to supply planned energy during it. |
| Sweeteners and warnings | Read the sweetener ingredients and any laxative-effect warning on the exact pack. GOV.UK requires that warning for foods containing more than 10% polyols. | If polyols do not suit me, I want to know what is in the mint before carrying it on a run. |
| Low blood glucose | Keep a sugar-free mint separate from fast-acting carbohydrate used for a hypo. The NHS lists glucose or dextrose tablets, glucose gel and sugary drinks as examples that raise blood glucose quickly. | When I plan for exercise-related hypos, I need to follow my diabetes plan rather than rely on a sugar-free mint. |
Tesco lists three Polo Sugar Free Mints at 10 kcal. That serving does not serve the same purpose as the carbohydrate foods the British Dietetic Association discusses for exercise.
Choose the mint for its flavour. If you need food around exercise, consider the activity, what you have eaten beforehand and suitable carbohydrate-containing options.
Waitrose warns that excessive consumption of its isomalt-containing Sulá Mint Humbugs may produce laxative effects. Polo’s retailer listing carries a similar warning for some people.
Check the ingredients and warning on the exact pack, particularly if you know polyols do not suit you.
The NHS advises prompt treatment with something that raises blood glucose quickly when a reading is below 4 mmol/L. Sugar-free mints are not a substitute for the fast-acting carbohydrate in a person’s diabetes plan.
Keep the specified hypo treatment available during exercise and follow the individual plan for its use.
These examples illustrate why the ingredients, serving information and warnings on a particular pack matter more than the brand name alone.
Polo Sugar Free is a pressed mint listed by UK retailers in rolls and multipacks.
Tesco lists Trebor Mighties as extra-strong sugar-free mints in a 12.5 g pack.
M&S lists a sugar-free version of its Curiously Strong Mints for the UK.
These are sugar-free mint options for someone who wants a mint around a 5k, not products to rely on for run fuel or hypo treatment.

A 22 g grape-flavoured mint option for someone who wants a sugar-free mint around a run. Check the pack’s serving information, sweeteners and warnings if they matter to you; it should not replace run fuel or hypo treatment.
Do not choose them as planned run fuel. Tesco lists three Polo Sugar Free Mints at 10 kcal, while the British Dietetic Association identifies carbohydrate as the main fuel for exercising muscles. A mint and a carbohydrate-containing food serve different purposes.
Not necessarily. University College London Hospitals says snacks for energy may be needed for activities lasting longer than 60 minutes; during shorter activities, snacks may instead be needed for hypoglycaemia prevention or treatment. Duration and individual circumstances matter more than the distance alone.
Do not rely on sugar-free mints for hypo treatment. The NHS advises something that raises blood glucose quickly when a reading is below 4 mmol/L, listing options such as glucose tablets, glucose gel and sugary drinks. Follow your individual diabetes plan for exercise and treatment.
GOV.UK states that foods containing more than 10% polyols must warn that excessive consumption may cause a laxative effect. Formulations differ, so check the sweeteners and warning on the pack you are buying.
