Routine exercisers buying a drink with a snack
If you want a drink for a gym session, walk, run or class, plain water keeps the drink separate from the food in your snack. The NHS recommends water for replacing fluid lost through physical activity.
Who is this choice for?
Shoppers who prefer flavour without listed sugars
A sugar-free flavoured water may appeal if you do not enjoy plain water. Read both the nutrition panel and ingredients: Volvic UK lists 0g sugars per 100ml for its Touch of Fruit Sugar Free Strawberry 750ml, alongside sweeteners and a preservative.
People exercising for longer or in hot conditions
A bottle chosen for an ordinary session should not be treated as an individual hydration plan for more demanding exercise. Victoria State Government’s Better Health Channel notes that fluid needs vary with conditions, health, intensity and duration.
What should you check?
Start with the type of drink you find comfortable before activity, then check the label and choose a bottle format that fits how you will use it.
| Priority | What to check | Your needs |
|---|---|---|
| Plain or flavoured | Check whether the drink is plain water or flavoured water. For a sugar-free flavour, read sugars per 100ml and the ingredient list; a sugar-free drink may contain sweeteners. | I want a drink alongside my snack without listed sugars, and flavour matters more to me than choosing plain water. |
| Still or sparkling | Check whether the water is carbonated. If choosing a flavoured sparkling drink, read its ingredients and nutrition panel rather than assuming it is unsweetened. | Fizz may feel uncomfortable just before I move, so I would choose still water for that session. |
| Food and fluid | Keep the drink and snack as separate choices. Mineral values on a water label describe its composition; they do not establish an individual plan for long, hot or high-sweat exercise. | I am choosing water for fluid, not expecting it to provide the food in my pre-workout snack or settle my needs for a demanding session. |
| Bottle format | Compare the stated bottle volume and number of bottles. Decide whether you need one to carry or a larger pack to keep at home. | A small bottle fits in my bag; for repeated sessions, I may prefer bottles I can keep ready at home. |
Common buying mistakes
-
Treating sugar-free flavoured water as plain water
“Sugar free” describes the sugar content, not the full ingredient list. Volvic UK’s Touch of Fruit Sugar Free Strawberry 750ml lists 0g sugars per 100ml as well as acesulfame K, sucralose and potassium benzoate.
Read both the nutrition panel and ingredients. Choose plain water if you specifically want to avoid flavourings or sweeteners.
-
Assuming mineral water is an individual sports drink
Declared mineral composition differs between waters. It does not, by itself, establish what someone needs during a particular workout; the Better Health Channel notes that fluid needs vary with conditions, health, intensity and duration.
Use the mineral declaration to understand what is in the water, and seek individual guidance where your exercise conditions or health circumstances call for it.
-
Choosing fizz without considering timing
Carbonation can feel uncomfortable for some people immediately before exercise.
If you are unsure how fizz feels before activity, choose still water for the session nearest your workout.
-
Overlooking bottle size
A multipack of larger bottles serves a different use from an individual bottle carried with a snack.
Check the volume of each bottle and the number in the pack against where you plan to drink it.
Brand and retailer references
These examples show how the named water ranges differ; check the label of the particular bottle you choose.
Highland Spring
Its range includes plain water and flavoured still water, giving shoppers a choice between an unflavoured drink and a sugar-free labelled flavour.
- Highland Spring lists 0g sugars and 1kcal per 100ml for the flavoured-still products displayed on its range page.
- Check the nutrition panel for the particular flavour and bottle rather than applying those figures to every Highland Spring product.
Evian
An unflavoured natural mineral-water option with a declared mineral composition.
- Evian lists calcium 80mg/L, magnesium 26mg/L and sodium 6.5mg/L for its 1L water.
- Those values describe the 1L water; they are not an individual sports-electrolyte recommendation.
Volvic
Its range includes plain natural mineral water and sugar-free flavoured water.
- Volvic UK lists 0g sugars per 100ml for its Touch of Fruit Sugar Free Strawberry 750ml.
- That 750ml drink also lists sweeteners and potassium benzoate; check the ingredients on the specific bottle you buy.
Buxton
Buxton offers still and sparkling natural mineral water for shoppers deciding whether they want carbonation.
- Buxton publishes a mineral composition for its sparkling water.
- The sparkling format may be uncomfortable immediately before activity for someone who does not tolerate fizz.
Tesco
Tesco Groceries lists own-label and named waters in still, sparkling, flavoured and larger-pack formats.
- The range lets shoppers compare bottle and pack formats for carrying or keeping at home.
- Check the individual label: a flavoured product should not be assumed to have the same ingredients as plain water.
Sainsbury's
Sainsbury's has an own-label sparkling spring-water option alongside the still-versus-sparkling choice.
- Its listed 2L sparkling spring water has spring water and carbon dioxide as ingredients.
- Choose it before exercise only if carbonation feels comfortable for you.

Questions about bottled water before exercise
Is plain bottled water a sensible drink with a pre-workout snack?
Yes, for a routine workout when you want a plain drink alongside food. The NHS recommends water for replacing fluid lost through physical activity; choose the snack separately rather than expecting water to provide it.
Does sugar-free flavoured water contain only water?
Not necessarily. Volvic UK’s Touch of Fruit Sugar Free Strawberry 750ml lists 0g sugars per 100ml, but also lists flavouring, sweeteners and potassium benzoate. Read the ingredients on the particular bottle you choose.
Should I choose mineral water for electrolytes before training?
Do not assume a mineral-water label gives you an individual electrolyte plan. Mineral compositions differ, while the Better Health Channel notes that fluid needs vary with conditions, health, exercise intensity and duration.
Can I drink sparkling water before exercise?
Yes, if you find carbonation comfortable before activity. For an unsweetened choice, check the ingredients: Sainsbury's lists spring water and carbon dioxide for its 2L sparkling spring water. Choose still water if fizz feels uncomfortable before you move.
