Choose plain still or sparkling water if you want a post-gym drink without flavourings or sweeteners. If you prefer flavoured water, compare the sugars figure per 100ml and the ingredients on the exact bottle: “sugar-free” and “no added sugar” do not, by themselves, tell you whether it contains sweeteners or declares 0g sugars.
If you want water without added flavourings or sweeteners after an ordinary session, start with plain bottled water. The NHS advises drinking extra fluid after sweating from physical activity; choose a bottle format that fits how and where you will use it.
A sugar-free or no-added-sugar flavoured water may suit your taste, but the claims are not interchangeable. Check the exact flavour’s sugars per 100ml and ingredients before choosing it.
If sweeteners, acids or preservatives affect your choice, read beyond the front-of-pack sugar claim. The ingredient list distinguishes a flavoured drink from plain water and lets you check for particular additives.
Decide whether you want plain or flavoured water first, then compare the exact product’s nutrition panel, ingredients and bottle format.
Choose it when: You want water without the sweeteners and flavourings used in some flavoured drinks.
Bear in mind: It will not provide a flavoured taste; choose still or sparkling according to your preference.
Choose it when: You want flavour and the exact bottle’s sugar declaration fits your requirement.
Bear in mind: Sugar-free flavoured water can contain sweeteners; Volvic’s Lemon & Lime Sugar Free lists acesulfame K and sucralose.
Choose it when: You specifically want a flavoured drink labelled no added sugar and its full label suits you.
Bear in mind: The claim does not mean 0g sugars or no sweeteners. Sainsbury’s lemon-and-lime example declares less than 0.5g sugars per 100ml and contains sucralose.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars | Read sugars per 100ml on the exact flavour. Consider the bottle quantity as well as the per-100ml figure; do not treat “low sugar” as 0g. | I want to know what the drink declares before putting a bottle in my gym bag. Volvic UK lists 0g sugars per 100ml for Lemon & Lime Sugar Free, but 2.3g per 100ml for its regular Strawberry Touch of Fruit. |
| Ingredients | Check for sweeteners, acids, flavourings and preservatives, particularly on flavoured drinks. A sugar claim does not replace the ingredient list. | Flavour appeals to me, but I may not want certain added ingredients. I would compare the full lists rather than assume two similarly labelled drinks contain the same things. |
| Bottle format | Compare the individual bottle size with how you will carry and store it. Check the exact pack’s instructions for an opened bottle. | A smaller bottle may fit my journey home; a larger bottle or multipack may make more sense where I keep water at home. The NHS advises extra fluid after sweating, rather than a single bottle size for everyone. |
| Still or sparkling | Confirm whether the drink is still or carbonated, especially when choosing a flavoured water or multipack. | I want a format I will enjoy drinking after exercise. If I prefer fizz, I will check that the particular bottle is sparkling rather than assuming every product in a range is. |
Volvic UK describes its regular Strawberry Touch of Fruit as low sugar, yet lists 2.3g sugars per 100ml. A no-added-sugar claim is not a substitute for a nutrition figure either.
Compare sugars per 100ml on the exact bottle. If you specifically want a declared 0g, check for that figure rather than choosing by the front label alone.
Volvic’s Lemon & Lime Sugar Free lists sweeteners, while Sainsbury’s no-added-sugar lemon-and-lime sparkling water lists sucralose. Those ingredients matter if you prefer to avoid them.
Read the complete ingredient list. Choose plain water if your aim is to avoid added flavourings and sweeteners.
A pack intended for storage at home may not be the format you want to carry after the gym. Opened-bottle instructions can also differ between products.
Check the size of each bottle, not just the number in the pack, and follow its own storage instructions after opening.
These examples show why the exact product and flavour matter more than the brand name alone.

No. Check the sugars figure per 100ml and ingredients rather than treating the two labels as interchangeable.

Choose plain still or sparkling water and a bottle size that fits your routine. The NHS advises extra fluid after sweating from physical activity; check the exact product label if you need to confirm its ingredients.
Yes. Volvic UK lists acesulfame K and sucralose in its Lemon & Lime Sugar Free product, despite declaring 0g sugars per 100ml. Read the ingredients if avoiding particular sweeteners matters to you.
Do not judge a snack or meal by the water label: bottled water is a drink, and its ingredients and nutrition panel tell you what that particular product contains. If you have individual requirements after prolonged or very sweaty exercise, seek appropriate personal advice rather than assuming an ordinary bottled water covers them.
Check the exact flavour’s ingredients, sugars per 100ml, bottle quantity and storage instructions, alongside any front-of-pack sugar claim. UK government food-labelling guidance identifies ingredients, net quantity and date marking among the information provided on prepacked foods.
