Who is this choice for?

Shoppers avoiding added sugar

If you want a fizzy mixer beside your snack without added sugar, look for the exact claim and read the ingredients. A zero-sugar nutrition panel is useful information, but a light or low-calorie description alone does not answer the added-sugar question.

Shoppers who prefer to avoid artificial sweeteners

You may prefer a drink containing some sugar instead. Fever-Tree lists fruit sugar in its Refreshingly Light Indian and Cucumber tonics. In a 2019 description of its Light range, Fentimans said it used no artificial sweeteners and contained 4.8 g sugars per 100 ml; check the current pack before choosing.

People planning food after demanding exercise

If another hard session follows soon, choose the mixer as a drink, not as the snack. The British Dietetic Association advises carbohydrate-rich foods and fluids when quick recovery after exercise is required.

What should you check?

Decide whether the exact no-added-sugar claim matters to you, then compare the nutrition panels on the same serving basis and plan the food you will have with the drink.

Priority What to check Your needs
Sugar claim Read the precise on-pack claim and ingredient list. Fever-Tree lists fructose or fruit sugar in its Refreshingly Light Indian and Cucumber tonics, so their light positioning does not establish a no-added-sugar choice. “No added sugar” is the distinction that matters to me; I do not want to choose by the word “light” alone.
Sugars per serving Compare both the amount and serving size. Tesco Groceries lists 0 g sugars and 4 kcal per 250 ml for Tesco Low Calorie Indian Tonic, and 0 g sugars and 5 kcal per 250 ml for its Schweppes Slimline Tonic listing. I want to know what a glass contains, rather than rely on a reduced-calorie description.
Ingredients Check the current pack for sweeteners and quinine if you avoid particular ingredients. Tesco Groceries lists aspartame in its Schweppes Slimline Tonic listing; Fever-Tree lists fruit sugar in its Refreshingly Light tonics. A low-sugar drink only suits me if I am comfortable with its ingredients and its style of mixer.
Food alongside the drink Keep the drink separate from your food choice. The British Dietetic Association advises carbohydrate-rich foods and fluids when quick recovery after exercise is required. If I need to refuel before another session, I will have food as well as a drink.
Current pack and stock Confirm the ingredients, nutrition panel and availability before relying on a particular product. Tesco has listed Sunsip No Added Sugar Tonic Water by that exact name; its listing also showed it out of stock when consulted. If the exact claim is essential, I need to check that the product I can buy carries it.

Common buying mistakes

  • Reading “light” as “no added sugar”

    A lower-calorie comparison does not settle the added-sugar question. Fever-Tree lists fruit sugar in its Refreshingly Light Indian and Cucumber tonics.

    If the exact claim matters, check for it on the pack and inspect the ingredients rather than relying on “light” in the name.

  • Treating the mixer as the recovery snack

    A drink chosen for its zero-sugar content does not take the place of food when quick refuelling is needed after exercise.

    Have the mixer alongside food and fluids. The British Dietetic Association advises carbohydrate-rich foods and fluids when quick recovery is required.

  • Skipping the ingredient list

    Drinks with similar sugar figures can use different ingredients. Tesco Groceries lists aspartame in its Schweppes Slimline Tonic listing, while Fever-Tree lists fruit sugar in its Refreshingly Light tonics.

    Read the current pack if you avoid a particular sweetener or quinine-containing drinks.

  • Assuming an exact-label option is ready to buy

    Tesco’s listing named Sunsip No Added Sugar Tonic Water but showed it out of stock when consulted.

    Check stock and the current pack. If it is unavailable, decide whether a zero-sugar tonic meets your preference without assuming it carries the same claim.

Brand and retailer references

These examples show why a brand’s light, slimline or no-added-sugar wording still needs checking on the particular drink; not every example below is a ready-to-drink mixer.

Tesco

An own-label tonic example for comparing sugars on a stated serving size.

  • Tesco Groceries lists its Low Calorie Indian Tonic with 0 g sugars and 4 kcal per 250 ml.
  • Check the pack for the exact claim and current ingredients; “low calorie” is not itself a no-added-sugar claim.

Schweppes

A slimline tonic option for shoppers comparing zero-sugar mixers.

  • Tesco Groceries lists Schweppes Slimline Tonic with 0 g sugars and 5 kcal per 250 ml.
  • Its researched listing includes aspartame; check the ingredients on the pack you choose.

Fever-Tree

Refreshingly Light tonic styles for shoppers whose aim is not strictly no added sugar.

  • The brand lists Refreshingly Light Indian and Cucumber tonic options.
  • Fever-Tree lists fructose or fruit sugar for those styles; their light description does not make them no-added-sugar options.

Fentimans

A Light range described by the brand as lower in sugar, rather than sugar-free.

  • In its 2019 range announcement, Fentimans described drinks made without artificial sweeteners.
  • That announcement gave 4.8 g sugars per 100 ml. Check the current product label rather than treating “Light” as a no-added-sugar claim.

Britvic

Its drinks portfolio provides a reminder to distinguish squash from a ready-to-drink mixer.

  • Sainsbury’s lists Robinsons Lemon Squash with a No Added Sugar name and 0 g sugars per 250 ml when diluted.
  • Robinsons squash is diluted before drinking; it is not a tonic-water substitute by name alone.

Sainsbury's

A retailer example illustrating the difference between a no-added-sugar claim and zero sugars.

  • Sainsbury’s lists a no-added-sugar pineapple and coconut juice drink with 4.8 g sugars per 100 ml.
  • That fruit drink is not a tonic recommendation; use its label example to remember to check the sugars figure separately.

Questions about post-gym mixers

Does “no added sugar” mean sugar-free?

No. Sainsbury’s lists 4.8 g sugars per 100 ml for its no-added-sugar pineapple and coconut juice drink. It is not a mixer example, but it shows why you should read the sugars figure as well as the claim.

Are Fever-Tree Refreshingly Light tonics no-added-sugar choices?

Do not choose the researched Indian or Cucumber styles on that basis: Fever-Tree lists fructose or fruit sugar for them. Their light description refers to a different distinction, so check the ingredients if avoiding added sugar is your priority.

Can a zero-sugar mixer be my post-gym snack?

Have it as a drink alongside food, not as the food itself. When quick recovery after exercise is required, the British Dietetic Association advises carbohydrate-rich foods and fluids.

Do I need a special recovery drink after every gym visit?

Not necessarily. The British Dietetic Association says carbohydrate needs depend on the training programme and overall dietary goals; consider how soon you will exercise again when planning your food and drink.

How do I check a mixer if I avoid certain sweeteners?

Read the ingredients on the current pack. Tesco Groceries lists aspartame in its Schweppes Slimline Tonic listing, but check the particular format you are buying rather than assuming every pack has the same formulation.
