For a 5k, choose mini mints for portable breath freshness rather than as your primary running fuel. For endurance exercise lasting 45–75 minutes, World Athletics describes a mouth rinse or small carbohydrate amount and lists 0–20 g of carbohydrate per hour; Sainsbury’s lists 2.4 g of available carbohydrate per 2.4 g serving of Trebor Extra Strong. If you intend to take in carbohydrate, consider your run duration and the amount stated on the pack instead of assuming a mint meets that plan.
The useful distinction is whether you want a measured carbohydrate amount or simply a mint you can carry before or after a run.
If you are planning carbohydrate intake, compare the amount per stated serving with the duration of your run. World Athletics’ guidance for 45–75-minute endurance exercise allows for a small carbohydrate amount, but that does not make a mint a complete fuelling plan.
A mint roll or compact pack may suit a pocket or running bag when freshness before or after the run is the aim. Keep that choice separate from any decision about carbohydrate intake.
A sugar-free mint addresses a preference to avoid sugar, not a plan to obtain sugar during a run. Check its sweeteners and consider whether you already tolerate the product; University Hospitals Sussex NHS Foundation Trust notes that large amounts of polyols can have a laxative effect.
Decide whether you need a stated carbohydrate amount or a convenient mint for freshness. Then compare serving information, format and ingredients on the particular pack.
| Priority | What to check | Your needs |
|---|---|---|
| Carbohydrate amount | Check carbohydrate per mint or stated serving, not only per 100 g. World Athletics lists 0–20 g per hour for 45–75-minute endurance exercise; Sainsbury’s lists 2.4 g of available carbohydrate per 2.4 g Trebor Extra Strong serving. | If I am planning carbohydrate intake for a run, I want to know the amount in the portion I would actually have, rather than count mints without a serving reference. |
| Carry format | Compare a roll, small pack or tin with the space available in your pocket or bag. Check whether the individual sweets and packaging suit when you intend to use them. | I want a mint that is easy to carry for breath freshness before or after a run; a portable pack alone does not tell me anything about fuelling. |
| Sugar and sweeteners | Check whether the product is labelled sugar-free and read its sweetener ingredients. For products containing polyols, University Hospitals Sussex NHS Foundation Trust warns that large amounts can have a laxative effect. | If avoiding sugar matters to me, I can choose a sugar-free mint for freshness without treating it as a source of sugar for my run. |
| Ingredients and dietary suitability | Read the current ingredients and highlighted allergens on the pack. Check dietary statements for that exact product: Sainsbury’s lists gelatine in Trebor Extra Strong, while Waitrose & Partners lists its own Mint Imperials as suitable for vegetarian and vegan diets. | I need to check the mint I am buying against my dietary requirements, rather than assume that similar-looking sweets use the same ingredients. |
A sugar-containing mint can provide a small amount of carbohydrate, but the amount depends on its serving size. Sainsbury’s lists 2.4 g of available carbohydrate per 2.4 g serving of Trebor Extra Strong; World Athletics’ guidance for 45–75-minute endurance exercise is based on exercise duration.
If you intend to take in carbohydrate, start with your expected run duration and a product with a usable serving reference rather than assuming a number of mints meets your plan.
Waitrose & Partners describes Polo Sugar Free as pressed sugar-free mints with sweetener. A sugar-free choice for freshness does not serve a goal of taking in sugar during a run.
Read the sweetener list on the specific pack. If it contains polyols, bear in mind University Hospitals Sussex NHS Foundation Trust’s warning about a laxative effect from large amounts.
Ingredients differ between products: Sainsbury’s lists gelatine in Trebor Extra Strong, whereas Waitrose & Partners labels its own Mint Imperials suitable for vegetarian and vegan diets.
Check the current pack for ingredients, highlighted allergens and any dietary-suitability statement that matters to you.
Sainsbury’s cautions that product ingredients can change. A listing can help narrow your choice, but it may not reflect the pack you receive.
Read the physical pack’s nutrition and ingredients before using the mint, particularly if a serving amount or particular ingredient affects your choice.
These examples help distinguish mint formats and product-specific ingredients; a brand name alone does not establish whether a mint suits a fuelling plan.

Four rolls offer a carryable mint format for freshness. For this Trebor Extra Strong product, Sainsbury’s lists 2.4 g of available carbohydrate per 2.4 g serving and gelatine in the ingredients; that small serving is not a fuelling plan.

This four-pack is an option if you want small mint packs for freshness before or after a run. If you intend to measure carbohydrate intake, check the current pack for the amount per mint or serving rather than treating the pack weight as a fuelling amount.

This sugar-free grape mint suits a choice centred on freshness while avoiding sugar, not one centred on taking in sugar during a run. Check the current pack’s sweeteners and serving information if either affects your choice.

Five chewy mint rolls offer a different texture from a pressed mint if you are choosing for freshness and carry format. Check carbohydrate per piece or serving on the pack if the amount matters to your run.

The XXL tin is a sugar-free spearmint option for freshness rather than a source of sugar during a run. Check the tin’s size against where you plan to carry it, and read the current sweetener ingredients if tolerance matters to you.
Do not rely on mini mints as your primary 5k fuel. World Athletics lists 0–20 g of carbohydrate per hour and describes a mouth rinse or small carbohydrate amount for endurance exercise lasting 45–75 minutes. Sainsbury’s lists 2.4 g of available carbohydrate per 2.4 g serving of Trebor Extra Strong, which gives you a portion reference but not a complete plan for your run.
A sugar-free mint is a choice for freshness while avoiding sugar, not a way to take in sugar during a run. Waitrose & Partners describes Polo Sugar Free as a mint with sweetener. Check the particular product’s ingredients: University Hospitals Sussex NHS Foundation Trust notes that large amounts of polyols can have a laxative effect.
Check the stated serving size and nutrition if carbohydrate amount matters, then read the ingredients for sweeteners, allergens and dietary suitability. The Food Standards Agency says allergens must be emphasised in the ingredients list of UK prepacked food. Read the current pack rather than relying only on an online listing, as Sainsbury’s cautions that ingredients can change.
