| Priority | What to check | Your needs |
|---|---|---|
| Exercise fuel | Decide whether you need a carbohydrate snack or drink for the activity. For glucose management, follow your own exercise plan rather than treating gum as a substitute. | If I need carbohydrate during a run, I want a product chosen for that purpose, not simply something pocket-sized. |
| Sugar-free choice | Check that the specific pack is labelled sugar-free and read its ingredients and nutrition information. Sugar-free describes the gum, not its suitability as run fuel. | I want something to chew around my run without choosing it for energy intake. |
| Ingredients | Read the sweetener list and pack warnings. UK food-labelling guidance requires a laxative-effect warning when a food contains more than 10% added polyols. | Before taking gum on a run, I want to check whether its ingredients and warnings matter to me. |
| Dry mouth | The NHS lists sugar-free gum among dry-mouth self-care options and separately advises regular sips of water. Do not use gum in place of a drink. | If my mouth feels dry, I may want a chew, but I still want water available. |
