Who these choices suit

People with diabetes choosing an everyday drink

Diabetes UK recommends water as an all-round drink. Plain bottled water is a straightforward choice for regular hydration; a flavoured sugar-free option may suit someone who prefers a different taste.

Shoppers who prefer flavoured water

Compare sugars per 100ml as well as the ingredient list. The listed Volvic and Sainsbury's flavoured waters contain sweeteners and other ingredients that plain water does not.

People who need to prepare for hypos away from home

Keep everyday hydration separate from hypo treatment. Sugar-free bottled water cannot provide the sugar needed to treat a hypo; carry and follow the treatment agreed in your care plan.

What to check when choosing

Decide whether you want plain or flavoured water, then check the exact bottle’s label and a pack size that suits where you will drink it.

PriorityWhat to checkYour needs
Plain water Check that the ingredient list is water alone, or water and carbon dioxide for a sparkling option. Compare bottle size and still or sparkling format. I want an everyday drink without added sugar or sweeteners. I can choose still or sparkling according to preference.
Flavour and sugars Read sugars per 100ml and the full ingredient list. Tesco Groceries lists 0g sugars per 100ml for Volvic Lemon & Lime Sugar Free; Sainsbury's lists below 0.5g per 100ml for its Strawberry & Kiwi No Added Sugar water. Plain water does not appeal to me, but I want to compare flavoured options without assuming that “no added sugar” means 0g sugars or water-only ingredients.
Hypos Keep the fast-acting carbohydrate specified in your agreed hypo-treatment plan separate from sugar-free water. Diabetes UK distinguishes sugary drinks used for hypos from sugar-free drinks for other occasions. If I need to treat a hypo while out, my hydration bottle must not take the place of my planned treatment.
Pack and storage Check bottle and pack size, current availability and the exact product’s instructions after opening. Sainsbury's says its 5L still spring water should be refrigerated and used within three days of opening. A small bottle may suit a bag; for a larger bottle or multipack, I need room to store it and a format I can use as directed.

Buying pitfalls

  • Assuming “no added sugar” means 0g sugars

    Sainsbury's lists sugars below 0.5g per 100ml for its Strawberry & Kiwi No Added Sugar water, while Tesco Groceries lists 0g per 100ml for Volvic Lemon & Lime Sugar Free.

    Compare the sugars value per 100ml on the exact bottle rather than treating the two labels as identical nutrition statements.

  • Assuming flavoured water has the same ingredients as plain water

    The listed plain Evian, Highland Spring and Volvic waters identify water as their ingredient. The listed flavoured examples also contain sweeteners, acids or flavourings.

    Choose plain water if you want to avoid those additions; otherwise, read the flavoured bottle’s complete ingredient list.

  • Using sugar-free water to treat a hypo

    Sugar-free water does not supply the sugar needed for hypo treatment. Diabetes UK treats sugary drinks for hypos as an exception to its everyday sugar-free drink advice.

    Keep your agreed hypo treatment available separately and use bottled water for hydration.

  • Overlooking instructions for an opened bottle

    A larger bottle may be used over several days. Sainsbury's instructs shoppers to refrigerate its 5L still spring water and use it within three days once opened.

    Check the instructions on the pack you buy and choose a size you can use accordingly.

A comparison of listed waters

This is a decision order, not an external quality ranking: plain water comes before flavoured drinks in line with Diabetes UK’s everyday-drink guidance, followed by flavoured examples distinguished by their listed sugars and ingredients. The order does not make a product suitable for every preference.

RankProductMain specificationsReason for positionPlatform
1 Evian Still 6x1.5L Still natural mineral water; 0g sugars per 100ml. The Joybuy listing identifies natural mineral water as the ingredient. This is a plain-water choice in a larger-bottle pack, consistent with Diabetes UK’s everyday water guidance. Joybuy
2 Volvic Still Natural Mineral Water 6x500ml Non-carbonated natural mineral water; six 500ml bottles. The Joybuy listing identifies 100% Volvic natural mineral water. The smaller bottles distinguish its pack format from the Evian example; the positions do not establish a nutritional advantage between them. Joybuy
3 Volvic Touch of Fruit Lemon & Lime Sugar Free 6x500ml Flavoured water; 0g sugars per 100ml on the Tesco Groceries listing. A flavour-led option rather than plain water. Tesco Groceries lists sweeteners, citric acid, flavourings and potassium benzoate, so check whether those ingredients suit you. Joybuy
4 Sainsbury's Strawberry & Kiwi No Added Sugar 4x500ml Flavoured spring-water drink; sugars below 0.5g per 100ml. Sainsbury's lists sweetener, acids, flavourings and preservatives. Its reported sugars value differs from the 0g-per-100ml Volvic example; compare the exact labels rather than treating this order as an overall verdict. Sainsbury's

No. Sugar-free water does not supply the sugar needed for hypo treatment. Diabetes UK distinguishes sugary drinks used for hypos from sugar-free alternatives for other occasions; follow your agreed hypo-treatment plan.
