Adults managing diabetes at home
If you want an everyday drink instead of juice or a sugary soft drink, plain water is a sensible starting point in Diabetes UK’s drink-choice guidance. The bottle’s label still matters if it is flavoured.
Who is choosing the bottle?
Families sharing a 2-litre bottle
Check whether the listing is for one 2-litre bottle or a multipack, and whether the household can follow the bottle’s storage instructions after opening.
People who prefer sparkling water
Carbonation can be a matter of taste. Look for plain sparkling water and check the label rather than assuming every fizzy drink has the same ingredients.
What should you check?
Choose the drink type first, then confirm the bottle format and the instructions for using it at home.
| Priority | What to check | Your needs |
|---|---|---|
| Plain water | Read the product description. If the drink is flavoured or contains juice, check its ingredients and nutrition label rather than treating it as plain water. | I want an everyday drink without choosing a sugary soft drink. Diabetes UK presents water as an all-round option for people living with diabetes. |
| Still or sparkling | Check that the sparkling option is plain water, not a sweetened fizzy drink. Tesco Groceries lists a plain 2-litre sparkling mineral-water option. | I prefer bubbles, but I still want to know what is in the bottle. |
| Bottle and pack size | Confirm that each bottle holds 2 litres, then check the number of bottles in the pack. A 1.5-litre listing is a different format even when the brand is familiar. | For a shared household bottle, I need the intended size without mistaking a multipack’s total volume for the volume of each bottle. |
| Mineral-water choice | If the source or mineral composition matters to you, read the exact product listing. Also check the bottle size and current stock status. | I may prefer a named mineral water, but I do not want the brand name to stand in for a label or format check. |
| After opening | Follow the instructions on the bottle you buy. Tesco Groceries directs buyers of its 2-litre still mineral water to refrigerate it after opening and consume it within 3 days. | Our household needs a bottle size we can use within its stated after-opening period. |
What can go wrong?
-
Assuming every drink labelled as water is plain water
Flavoured waters and drinks containing juice may have different ingredients from plain still or sparkling water. Diabetes UK distinguishes water from sugary everyday drinks in its guidance for people living with diabetes.
Read the ingredients and nutrition label when the product is flavoured, rather than deciding from the word ‘water’ on the front.
-
Choosing a brand without checking the bottle size
Tesco Groceries listed a 2-litre Evian bottle, while the Buxton and Volvic retailer examples listed by Ocado and Morrisons were 1.5 litres. Tesco’s Evian listing was marked out of stock on 2 October 2026.
Check each listing’s net contents, pack count and current stock status before comparing it with a 2-litre bottle.
-
Using bottle capacity as a personal drinking target
A 2-litre bottle describes the packaging; it does not set an individual daily intake.
Choose the size for household use rather than treating the full bottle as a personal prescription.
-
Overlooking instructions after opening
Tesco Groceries directs buyers of its 2-litre still mineral water to refrigerate it after opening and consume it within 3 days.
Read the instructions on your particular bottle, especially if a shared bottle may remain open for several days.
Which brands and formats are relevant?
A brand reference is useful only alongside the exact bottle size and pack configuration.
Tesco
Tesco Groceries lists own-label still and sparkling mineral water in 2-litre bottles.
- The still-water listing gives an after-opening refrigeration instruction and a 3-day consumption period.
- Check that the sparkling bottle selected is plain water rather than a flavoured drink.
Sainsbury's
Sainsbury’s Groceries lists own-label still spring water as a single 2-litre bottle and as a six-pack of 2-litre bottles.
- The two listings offer different pack configurations using the requested bottle size.
- Check which pack configuration is selected before ordering.
Evian
Tesco Groceries lists a 2-litre Evian natural mineral-water bottle with declared mineral composition.
- The listed bottle matches the requested 2-litre format.
- Tesco’s listing was marked out of stock on 2 October 2026; check its current status.
Highland Spring
Bestway Wholesale lists Highland Spring still spring water as a case of six 2-litre bottles.
- Each bottle in that wholesale case is listed as 2 litres.
- A wholesale case is not the same pack configuration as a supermarket single bottle; check the retailer and pack before comparing them.
Buxton
The Ocado example is Buxton still natural mineral water in a six-pack of 1.5-litre bottles.
- The listing identifies the water type and the size of each bottle.
- That 1.5-litre example does not meet a requirement for individual 2-litre bottles.
Volvic
The Morrisons example is a 1.5-litre Volvic still mineral-water bottle.
- Its listed bottle size makes the format clear.
- If 2 litres per bottle is essential, check an exact 2-litre listing rather than substituting this example.

Common questions
Is plain bottled water an everyday choice for someone living with diabetes?
Yes. Diabetes UK presents water as an all-round everyday drink for people living with diabetes. That general drink-choice guidance does not replace an individual care plan.
Can I choose sparkling water instead of still?
Plain sparkling water is an option if you prefer carbonation. Check the exact product label so you do not confuse it with a sweetened fizzy drink.
Do I need to choose a particular mineral-water brand?
For this everyday drink choice, focus first on whether the product is plain water and whether its bottle size suits your household. If you prefer a particular mineral source, check the exact 2-litre listing and its availability rather than relying on the brand name alone.
How should I keep a 2-litre bottle after opening it?
Follow that bottle’s label. Tesco Groceries instructs buyers of its 2-litre still mineral water to refrigerate it after opening and consume it within 3 days; do not assume the same period applies to another product.
