For everyday hydration, plain still or sparkling water is a straightforward choice; Diabetes UK calls water the best all-round drink for people with diabetes. If you prefer flavoured water, check the sugars value on the exact bottle rather than assuming every fruit-flavoured product is sugar-free. Keep your everyday water separate from the fast-acting carbohydrate recommended by the NHS for a hypo.
The useful distinction is between a routine drink, a flavoured alternative and something kept separately for a hypo.
Diabetes UK identifies water as an all-round drink for people with diabetes. If you prefer bottled water, choose a still or sparkling format you will use, then consider bottle size and storage rather than looking for a diabetes-specific mineral profile.
Flavoured waters differ even within one brand. Volvic lists 0g sugars per 100ml for its Sugar Free Strawberry 1.5L, but 2.3g per 100ml for its Lemon & Lime Touch of Fruit 500ml. Check the nutrition panel for the flavour and pack you are buying.
An everyday bottle of plain or zero-sugar water is not a fast-acting carbohydrate. If you use insulin or another medicine that can cause hypos, keep your usual hydration drink separate from the treatment specified in your personal diabetes plan; NHS hypo guidance gives examples of drinks and foods that raise blood glucose quickly.
Start with whether you want plain or flavoured water, then read the exact bottle label and choose a pack format that fits how you will use it.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars | For flavoured water, compare “of which sugars” per 100ml and per serving on the exact pack. Volvic lists 0g per 100ml for Sugar Free Strawberry 1.5L, against 2.3g per 100ml and 5.8g per 250ml serving for Lemon & Lime Touch of Fruit 500ml. | I want flavour without assuming that fruit imagery or a “low sugar” description means the drink contains no sugars. |
| Drink format | Choose between plain still and plain sparkling water by preference. The NHS suggests sparkling water as an option if you dislike plain water; Buxton notes that its sparkling water has a lower pH than its still water and raises a dental consideration with frequent, high-volume use over time. | Carbonation might make plain water more appealing to me, or I might prefer still water for regular drinking. |
| Ingredients | Read the ingredients alongside the nutrition panel. Volvic lists acesulfame K and sucralose in its Sugar Free Strawberry 1.5L; a “no added sugar” statement does not replace checking the sugars line for an individual bottle. | If I choose a sweetened flavour, I want to know which ingredients it contains and check them against any individual dietary advice I follow. |
| Hypo planning | Do not count plain or zero-sugar water as a fast-acting carbohydrate. NHS guidance for a hypo includes fruit juice, a sugary fizzy drink, glucose tablets, jelly babies or glucose gel; follow your personal treatment plan. | My everyday water and my hypo treatment need separate places in my bag or at home. |
| Pack size | Check the stated bottle volume, number of bottles and space needed to store them. Decide whether individual bottles or a larger pack suits where you will drink the water. | I may want a bottle to carry, or a larger format for home; the same pack will not suit every situation. |
Names and front-of-pack wording are less useful than the nutrition panel and ingredients of the bottle in your hand.
Volvic’s Sugar Free Strawberry 1.5L lists 0g sugars per 100ml, while its Lemon & Lime Touch of Fruit 500ml lists 2.3g per 100ml. The shared brand name does not make their nutrition values interchangeable.
Compare “of which sugars” per 100ml and the stated serving size for the exact flavour and pack.
Plain and zero-sugar water do not supply the fast-acting carbohydrate described in NHS guidance for raising low blood glucose.
Keep your hydration drink separate from the hypo treatment in your personal diabetes plan.
Highland Spring’s flavoured-still range page states both no added sugar and 0g sugars per 100ml. That range information is not a substitute for checking the label when you select a particular bottle.
Read the current sugars value, serving size and ingredients, especially when switching flavours or pack sizes.
Evian and Buxton publish mineral-composition details, but those figures do not establish a diabetes-specific advantage for either water. Buxton’s pH information concerns its still and sparkling formats, not diabetes treatment.
Choose a plain water you prefer drinking and a practical pack size; follow individual clinical advice where it affects your choice.
These examples show why it helps to compare named ranges and variants rather than treating a brand as one type of water.
Offers plain water and a flavoured-still range; its range page lists 750ml and 1.25L formats.
Offers plain mineral water and both sugar-free and sugar-containing Touch of Fruit variants.
Offers plain still and sparkling natural mineral water in several pack sizes.
Offers plain natural mineral water; its 1L product page gives a mineral breakdown.
A retailer whose water listings include own-label options and branded bottled waters.
These options cover plain still water, plain sparkling water and sugar-free flavoured-water formats. Compare the stated pack sizes, then check the current label of any flavoured bottle for its sugars value and ingredients.

A strawberry-flavoured still-water option in a 1.25L bottle. Check the current nutrition panel and ingredients of this exact bottle before choosing it for its sugar-free description.

A strawberry-flavoured option in six 500ml bottles for carrying individually. Check the sugars value and ingredients on this pack; nutrition figures for Volvic’s 1.5L Strawberry bottle should not be assumed to describe this variant.
No diabetes-specific bottled water is needed for routine hydration. Diabetes UK says there is no specific diabetes diet and identifies water as an all-round drink; choose a plain water format you prefer, or check the nutrition panel if you want flavour.
Choose by drinking preference rather than expecting a diabetes-specific benefit from carbonation. The NHS suggests sparkling water if you dislike plain water. Buxton says its sparkling water has a lower pH than its still water and raises a dental consideration for frequent, high-volume use over time.
No: the terms do not describe the same sugars value. Volvic lists 0g sugars per 100ml for Sugar Free Strawberry 1.5L, while its Lemon & Lime Touch of Fruit 500ml, described as low sugar, lists 2.3g per 100ml. Read the panel on the exact bottle.
No. Plain and zero-sugar water do not provide the fast-acting carbohydrate in NHS hypo guidance. Follow your personal hypo plan; the NHS gives examples including fruit juice, a sugary fizzy drink, glucose tablets and glucose gel, and advises urgent help for severe symptoms or unconsciousness.
Read both the sugars value and the ingredients for the exact variant. For example, Volvic lists 0g sugars per 100ml for Sugar Free Strawberry 1.5L and includes acesulfame K and sucralose in its ingredients. Discuss individual dietary questions with your diabetes healthcare team.
