Gym-goers who want a fizzy drink
Individual bottles may suit an occasional chilled drink after a routine workout. If replacing fluid lost through sweating is the main aim, the NHS recommends water.
Who is a mixer case for?
Tonic drinkers watching their sugar intake
A 12-pack offers individual serves, but the word ‘slimline’ is not a substitute for checking the current sugar, sweetener and serving information on the label.
People who need to refuel soon after training
A mixer can accompany food, but it is not a recovery snack. The British Dietetic Association advises carbohydrate-rich food and fluids when quick recovery is required.
What should you check before buying?
Decide whether you need a drink, food for refuelling, or both before choosing a flavour and pack format.
| Priority | What to check | Your needs |
|---|---|---|
| Fluid after sweating | Consider what you will drink to replace lost fluid. The NHS recommends water after physical activity. | After a sweaty session, I want a drink, but I do not need tonic flavour to meet that aim. |
| Quick refuelling | If you need quick recovery, plan carbohydrate-rich food and fluids, as the British Dietetic Association advises. Do not count a mixer as the snack. | When another demanding session is coming soon, I need to think about food as well as what is in my bottle. |
| Sugar and serving size | Compare sugar and energy per 100 ml and per bottle on the current label. Fentimans lists 0 g sugar per 100 ml for its Soda Water; Tesco describes Schweppes regular Tonic Water as containing sugar and sweetener. | If I will drink from the case regularly, I want to know what each serving contains rather than rely on ‘slimline’ or ‘regular’ alone. |
| Flavour and quinine | Choose tonic for its intended flavour; check its ingredients if quinine matters to you. Compare it with soda water when you do not want tonic bitterness. | I would choose tonic because I like its taste, not because the word ‘tonic’ suggests a recovery benefit. |
| Pack format | Check the number of bottles and volume per bottle against the occasions you have planned. Tesco lists both Schweppes tonic variants as 12 x 150 ml. | Twelve small bottles suit me only if that serving size and number of drinks match how I expect to use the case. |
What can go wrong with the choice?
-
Treating a mixer as a complete recovery snack
A fizzy drink does not automatically provide the food needed for quick refuelling. The British Dietetic Association advises carbohydrate-rich food and fluids when quick recovery is required.
Plan food separately if you need to refuel; have the mixer as an optional drink rather than the recovery plan.
-
Choosing slimline tonic by its name alone
The name does not tell you the current sugar, energy or sweetener content of each bottle.
Read the ingredients and nutrition declaration, including the serving size, before making a 12-pack a regular purchase.
-
Buying tonic to treat cramps
Quinine in tonic water is not a reason to use the drink as a treatment. UK Medicines and Healthcare products Regulatory Agency guidance says quinine should not be used routinely for nocturnal leg cramps.
Choose tonic for flavour, not for a presumed treatment effect. Seek medical advice about recurrent cramps or a previous reaction to quinine.

Frequently asked questions
Can a case of mixers replace a post-workout snack?
No: a mixer may be a drink alongside food, but it is not automatically a recovery snack. When quick recovery is needed, the British Dietetic Association advises starting to refuel with carbohydrate-rich food and fluids after exercise.
Is tonic water the drink to choose for rehydration?
Tonic water can contribute fluid, but the NHS recommends water for replacing fluid lost through physical activity. Choose tonic when you want its flavour, and check its label if sugar content affects your choice.
Should I choose regular or slimline tonic after exercise?
If you want tonic flavour in a 12-pack, compare the current sugar, energy and ingredient declarations before choosing. Tesco lists both Schweppes variants as 12 x 150 ml and describes its regular Tonic Water as containing sugar and sweetener; the word ‘slimline’ alone does not establish the nutritional difference.
Does the quinine in tonic make it a cramp treatment?
No. Do not choose tonic water as a treatment for cramps. UK Medicines and Healthcare products Regulatory Agency guidance says quinine should not be used routinely for nocturnal leg cramps and notes the relevance of previous adverse reactions to quinine, including that found in tonic water.
What should I read on a case-of-12 mixer label?
Check the bottle size and pack count, then read the current ingredients, nutrition declaration per 100 ml and serving, and any sweetener or allergen information relevant to you. This lets you compare the drinks you would actually serve, rather than relying on their variant names.
