People who have already eaten
If you want fresher breath on the way to a light workout, a portable sugar-free mint addresses that purpose without pretending to be a snack.
Who is this choice for?
People planning a demanding session
If you need food before longer or more demanding exercise, plan for that separately. The British Dietetic Association identifies carbohydrate as the main fuel source for exercising muscles.
People who react to sugar alcohols
Check for polyols such as sorbitol before taking mints to training. Royal Berkshire NHS Foundation Trust notes that some polyols can have a laxative effect when consumed in large quantities.
What should you check?
Decide whether you want breath freshness or pre-exercise food, then compare the exact mint’s serving information, sweeteners and pack format.
A mint for freshness
Choose it when: You have already eaten and want a small mint before a light session.
Bear in mind: Sugar-free does not mean calorie-free, and a mint is not a substitute for a fuelling snack.
Food before training
Choose it when: You need to eat before a longer or more demanding session; the British Dietetic Association advises a low-fat, carbohydrate-rich snack or light meal two to three hours beforehand.
Bear in mind: The timing needs planning around when you exercise and what you have already eaten.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars | Read the sugar-free claim and nutrition panel using the stated serving or per-100g basis. Tesco lists less than 0.5 g sugars per three Polo Sugar Free mints; its Trebor Mighties listing gives 0 g per 100 g. | I want a mint without sugar, but I will check the exact pack rather than treat “sugar-free” as a wider nutritional claim. |
| Exercise fuel | Check whether you need food before the session. Tesco lists 10 kcal per three Polo Sugar Free mints; the British Dietetic Association advises a carbohydrate-rich snack or light meal when pre-exercise fuelling is needed. | For a demanding workout, I need to plan food separately rather than rely on a mint. |
| Sweeteners | Read the ingredient list and any excessive-consumption warning. Tesco lists sorbitol in Polo Sugar Free; Waitrose lists 98 g polyols per 100 g for Smint XXL Peppermint. | If sugar alcohols have caused me problems before, I want to check the ingredients before carrying mints to exercise. |
| Pack format | Compare how you will carry and portion the mints. Tesco gives a three-mint serving for Polo Sugar Free; Waitrose describes Smint XXL Peppermint in a 50-piece tin. | A roll or tin needs to fit my journey to training, while leaving the serving and warning information easy to check. |
Common buying mistakes

Treating a sugar-free mint as a snack
A mint may serve a breath-freshening purpose, but it does not replace food needed before a demanding session. The British Dietetic Association identifies carbohydrate as the main fuel for exercising muscles.
If you need to eat beforehand, plan a low-fat, carbohydrate-rich snack or light meal in advance rather than relying on mints.
-
Overlooking polyol warnings
Royal Berkshire NHS Foundation Trust notes that polyols such as sorbitol can have a laxative effect in large quantities. The Waitrose Smint XXL and Sainsbury’s Ricola listings also carry excessive-consumption warnings.
Check the ingredient and warning panels. If a mint has previously caused symptoms, do not make it part of your immediate pre-workout routine.
-
Assuming every sugar-free mint uses the same sweeteners
The listed ingredients differ: Tesco identifies sorbitol in Polo Sugar Free and sorbitol plus sucralose in Trebor Mighties, while Marks & Spencer lists isomalt and sucralose in its Sugar-Free Clear Mint Drops.
Compare the exact pack’s ingredients, especially if a particular sweetener affects your choice.

Questions about mints before exercise
Can sugar-free mints replace a pre-workout snack?
Not when you need food for a demanding session. Tesco lists 10 kcal per three Polo Sugar Free mints, while the British Dietetic Association advises a low-fat, carbohydrate-rich snack or light meal two to three hours before exercise when pre-exercise fuelling is needed.
Why do polyols matter when choosing a mint before training?
Polyols are sweeteners used in some sugar-free mints, and Royal Berkshire NHS Foundation Trust notes that some can have a laxative effect in large quantities. Check the ingredients and excessive-consumption warning, particularly if similar products have caused you symptoms before.
Does “sugar-free” tell me everything I need to know?
No. The NHS notes that lower- or no-calorie sweeteners can help reduce sugar intake but do not automatically make a food healthy. For a mint before exercise, also read its serving information, ingredients and warnings, and decide separately whether you need food.
