Plain, unsweetened sparkling water is an option after an ordinary workout if you enjoy it and can drink comfortably; the NHS suggests sparkling water for people who dislike plain water. After prolonged or unusually sweaty exercise, consider fluid intake alongside food and whether the drink has the electrolyte content you need. UK Sports Institute guidance identifies dehydration and running out of fuel as separate recovery issues, so fizz alone does not address both.
The useful question is not simply whether the water is fizzy, but what you need from a drink after that particular session.
If the session was routine and you mainly want a drink you enjoy, plain sparkling water can be part of your fluid intake. The NHS names it as an option when plain water does not appeal; food remains a separate consideration after exercise.
After a prolonged or hot session, consider whether you need more than fluid. UK Sports Institute recovery guidance distinguishes dehydration from running out of fuel, so check the drink and your food plans separately.
If you want plain water rather than a flavoured formulation, read the ingredients as well as the sugar declaration. A flavoured sparkling drink can contain sweeteners, acids or flavourings even when its sugar content is very small.
Start with the demands of the workout, then compare the drink’s ingredients and a bottle size you will find practical to use.
| Priority | What to check | Your needs |
|---|---|---|
| Fluid and comfort | Consider whether you enjoy the carbonation and can drink a comfortable amount. A small controlled study published in Nutrients in 2026 reported lower final fluid recovery with carbonated water in its mild-dehydration trial; that result does not predict every person’s response. | After a routine session, I would rather drink plain water with fizz. If it makes me feel too full to keep drinking, I can choose still water instead. |
| Recovery beyond fluid | For prolonged, hot or unusually sweaty exercise, check the drink’s declared electrolyte content rather than assuming mineral water is a formulated replacement. Consider food separately when the session has left you needing fuel. | When another demanding session is coming soon, I want to think about the drink and my next meal, not expect a bottle of sparkling water to cover both. UK Sports Institute guidance treats dehydration and depleted fuel as distinct recovery issues. |
| Ingredients | Read the ingredients list and sugar declaration. Sainsbury’s lists spring water and carbon dioxide for its plain sparkling spring water, while M&S lists citric acid, flavourings, a preservative and steviol glycosides in its Summer Berries sparkling water. | I may enjoy a flavoured drink, but I want to know whether I am choosing plain water or a drink with added ingredients. A zero-sugar description alone does not answer that question. |
| Bottle format | Check the bottle volume and number of bottles in a pack against where you will keep and drink them. Format does not establish electrolyte content or recovery performance. | A smaller bottle may be easier for me to take out; larger bottles may suit drinking at home. Either way, I still need to choose the drink for the session itself. |
Plain sparkling water supplies fluid, but it does not provide a meal or the carbohydrate and protein you may need after demanding exercise. UK Sports Institute guidance identifies dehydration, depleted fuel and muscle damage as different recovery considerations.
Decide what the session calls for before choosing the drink. If food is part of your recovery plan, arrange that separately rather than relying on the water.
The words describe sugar content, not the whole ingredients list. M&S Summer Berries sparkling water, for example, lists citric acid, flavourings, a preservative and a sweetener.
If you want an unflavoured drink, look for water and carbon dioxide in the ingredients. For a flavoured option, check its full list and nutrition panel against your preferences.
Carbonation can affect drinking comfort. A small 2026 Nutrients study of rehydration after mild dehydration found lower voluntary intake and final fluid recovery with carbonated water than with its comparison drinks; individual experiences may differ.
If fizz leaves you uncomfortably full or you stop drinking sooner than intended, try still water. After a high-sweat session, check whether a non-carbonated drink with declared electrolytes better fits your needs.
A declared mineral content tells you what is in the water; it does not by itself establish that the drink replaces what was lost in a particular workout.
Once plain water fits the session, choose between bottles by ingredients, taste and format. If electrolyte content matters, compare the current label instead of relying on the brand name.
Ranges can contain both plain and flavoured drinks, so check the particular bottle rather than applying one product’s ingredients to an entire brand.
Its plain sparkling spring water is listed by the manufacturer in several bottle and pack formats.
Its UK range includes plain sparkling mineral water and flavoured Essenza drinks.
Perrier describes its plain sparkling water as having no sugar and zero calories.
Tesco lists own-brand plain sparkling natural mineral water in larger bottles and multipacks.
Its British Bottled Spring Sparkling Water is a plain 2 L option.
The retailer’s water range includes plain products and flavoured sparkling drinks.
These bottles are options for the plain-water choice after an ordinary workout when you prefer fizz. Compare their pack formats, and consider food or a drink with declared electrolytes separately if the session calls for more than fluid.

The individual bottles offer a format for taking plain sparkling water to a routine workout. This is an 8 × 500 ml pack; consider food separately when the session has left you needing fuel.

For plain sparkling water kept at home, this pack contains six 1 L bottles. Highland Spring publishes naturally occurring mineral values for its sparkling water, but those figures do not establish an exercise-specific electrolyte formulation.

This six-bottle pack is a smaller-bottle option for someone choosing plain sparkling water after an ordinary session. Each bottle is 500 ml; check the current mineral declaration if electrolyte content matters to your choice.

The six 1 L bottles offer a larger format of plain sparkling mineral water for routine drinking. If the workout calls for fuel or electrolyte replacement, assess those needs separately from the bottle size.

This 8 × 500 ml pack offers individual bottles of sparkling water for the plain-water route. If you need to assess electrolyte replacement after substantial sweating, check the current label rather than treating the pack format as evidence of its mineral content.
Yes, it can be an option for fluid intake after a routine workout if you enjoy it and can drink comfortably. The NHS suggests sparkling water for people who dislike plain water; consider food separately if the session has left you needing fuel.
After prolonged, hot or unusually sweaty exercise, assess your fluid and food needs rather than relying on plain sparkling water alone. UK Sports Institute guidance distinguishes dehydration from depleted fuel, while a small 2026 Nutrients study found lower final fluid recovery with carbonated water in its mild-dehydration trial.
No. Sainsbury’s lists only spring water and carbon dioxide for its plain sparkling spring water, whereas M&S lists flavourings, citric acid, a preservative and steviol glycosides for its Summer Berries sparkling water. Read the ingredients list to distinguish the particular drinks you are comparing.
Choose still water if carbonation limits how much you can comfortably drink. A small study published in Nutrients in 2026 observed lower voluntary intake with carbonated water after mild dehydration; your own comfort is also a practical reason to switch.
