Plain sparkling water is a reasonable choice after an ordinary workout if you want to replace fluid and prefer fizz: the NHS recommends water for replacing fluid lost through physical activity. For exercise in hot conditions, or prolonged activity with heavy sweating, consider whether you also need electrolytes rather than relying on plain water alone; the British Heart Foundation highlights that distinction. When choosing a multipack, check the can volume, pack count and ingredients so a flavoured drink is not mistaken for plain water.
The type of exercise and the way you carry or store your drinks matter more than the multipack label alone.
For an ordinary session where replacing fluid is the main aim, plain sparkling water offers a fizzy way to drink water. The NHS recommends water for replacing fluid lost through physical activity; check the ingredients if you want to avoid a sweetened soft drink.
Compare 330ml and 500ml cans according to what you can carry and how much you expect to drink at a time. Pack counts alone do not show the total amount of water.
Plain water may not be the only consideration when electrolyte losses matter. The British Heart Foundation advises choosing drinks with electrolytes in hot conditions, so consider your wider hydration plan rather than selecting a canned-water multipack as an electrolyte drink.
Choose it when: Replacing fluid after an ordinary workout is your main aim and you prefer carbonation; the NHS recommends water for fluid lost through physical activity.
Bear in mind: Plain water alone may not address electrolyte needs during exercise in hot conditions.
Consider it when: You exercise in hot conditions and need to replace electrolytes as well as fluid, as described by the British Heart Foundation.
Bear in mind: An ordinary workout does not automatically call for an electrolyte drink.
| Priority | What to check | Your needs |
|---|---|---|
| Fluid replacement | Check that the drink is water or sparkling water. Compare the can volume with the amount you plan to drink after your session. | After an ordinary workout, I want water in a fizzy format. The NHS recommends water for replacing fluid lost through physical activity. |
| Electrolytes | Consider the exercise duration, heat and sweating. Do not assume that a plain sparkling water serves the same purpose as an electrolyte-containing drink. | If I exercise in hot conditions or sweat heavily over a prolonged session, I need to consider electrolytes as well as fluid. The British Heart Foundation specifically advises electrolyte-containing drinks in hot conditions. |
| Can and pack size | Compare millilitres per can, number of cans and total pack volume. Check whether a can is described as resealable if you intend to keep it after opening. | A smaller can might suit my journey home; for longer sipping, I would check whether a larger can can be closed again. |
| Drink ingredients | Read the product description, ingredients and sugars per 100ml. Check flavoured cans individually rather than assuming every drink under a water brand is plain water. | I want to know whether I am buying plain sparkling water or a flavoured alternative, without judging its contents by the can design. |
Water replaces fluid, but plain sparkling water should not be assumed to meet electrolyte needs during exercise in hot conditions. The British Heart Foundation warns that drinking excessive plain water without enough electrolytes can affect fluid balance in endurance settings.
For hot conditions or prolonged, heavily sweaty activity, consider electrolyte replacement as part of your hydration plan rather than relying on a plain-water can alone.
Brands may sell both plain water and flavoured drinks. A familiar name or similar packaging does not establish the ingredients or sugar content of a particular can.
Read the exact product description, ingredients and sugars per 100ml before choosing a multipack.
Eight 330ml cans, 24 330ml cans and 12 500ml cans differ in both total volume and individual serving size.
Compare the volume per can and total litres, then decide which pack size fits how you will carry, store and drink it.
Oxford Health NHS Foundation Trust identifies fizzy drinks among acidic drinks relevant to dental erosion. That guidance does not establish an identical effect for every sparkling-water product.
If you frequently drink fizzy beverages or have concerns about your teeth, consider how often you drink them and ask a dentist for individual advice.
Check the exact drink and container format: a brand's bottled range or flavoured cans do not establish that its plain water comes in a canned multipack.
Perrier describes its carbonated mineral water as containing no sugar and zero calories. An Amazon UK listing identifies a plain Perrier multipack of 24 × 330ml cans.
Sanpellegrino describes a 330ml sleek can of S.Pellegrino carbonated natural mineral water.

Choose between this 24-can, 330ml ring-pull format and larger cans according to the serving size and pack count you want. Check the ingredients for your preferred type of sparkling water, and check the opening format if you expect to keep a can after opening.

This 12-can, 330ml orange-infused option is for shoppers considering a flavoured drink rather than plain sparkling water after an ordinary workout. Check its ingredients and sugars per 100ml against what you want from a flavoured alternative; do not treat it as an electrolyte drink on the basis of its water label.
It can be a choice when replacing fluid is your main aim: the NHS recommends water for fluid lost through physical activity. For exercise in hot conditions or prolonged activity with heavy sweating, consider whether you also need electrolytes rather than relying on plain water alone; the British Heart Foundation advises electrolyte-containing drinks in hot conditions.
Read the exact product name, ingredients and nutrition panel, including sugars per 100ml. A water brand or a can-shaped pack does not, by itself, tell you whether that particular drink is plain or flavoured.
The UK Department for Environment, Food & Rural Affairs lists drink cans as commonly collected at the kerbside in its 2026 collection list. That category means collection by at least 75% of local authorities across the four UK nations, not every household; follow your local council's instructions.
How often you drink fizzy beverages is worth considering. Oxford Health NHS Foundation Trust identifies fizzy drinks among acidic drinks relevant to dental erosion, but that does not establish the same effect for every plain sparkling water. Ask a dentist for individual advice if you have concerns about your teeth.
