After an ordinary workout, plain sparkling water is a reasonable choice if you enjoy the fizz: the NHS identifies water as the preferred way to replace lost fluid. Choose soda water or a flavoured variety according to its label, and choose tonic for its taste rather than as a recovery drink. When quick recovery matters after demanding or repeated exercise, the British Dietetic Association advises refuelling with carbohydrate-rich foods and fluids rather than relying on a mixer alone.
After a routine gym session, walk or ride, you may simply want a sparkling drink you enjoy. The NHS identifies water as the preferred way to replace lost fluid; choose a carbonated version if it suits you, and check the label if you want to avoid added sugar.
These drinks can look similar but have different ingredients. Fentimans lists no sugar for its Soda Water, while its Premium Indian Tonic Water contains sugar. Check the particular bottle rather than treating every mixer as interchangeable.
A sparkling drink can accompany food, but it should not stand in for refuelling when quick recovery is needed. The British Dietetic Association advises starting carbohydrate-rich foods and fluids soon after exercise in that situation.
Start with what the session calls for, then compare the drinks you would actually enjoy by their current ingredients and nutrition labels.
| Priority | What to check | Your needs |
|---|---|---|
| Fluid after routine exercise | Choose a drink you are comfortable drinking after exercise. Check whether it is plain water, flavoured water, soda or tonic. | I want fizz after an ordinary session, without expecting the drink to do more than contribute fluid. The NHS identifies water as the preferred way to replace lost fluid. |
| Sugar and ingredients | Compare sugars per 100ml and for the amount you plan to drink. Read the ingredients for sweeteners, flavourings and quinine where relevant. | If I want a particular flavour without unwanted sugar or sweeteners, I need to check that exact variety. Tesco lists 3.3g sugars per 100ml for its Indian Tonic Water; that figure does not describe plain sparkling water or other tonics. |
| Quick refuelling | Consider whether another demanding session is coming soon. Plan appropriate food and fluids rather than judging a mixer by its carbonation or flavour. | When I need to recover quickly for more exercise, a fizzy drink alone is not my refuelling plan. The British Dietetic Association advises starting carbohydrate-rich foods and fluids as soon as possible when quick recovery is required. |
| Flavour and format | Decide whether you prefer plain water, flavoured water, soda or bitter tonic. Check the pack size and the current label for the variety you choose. | Plain fizz may be enough for me; otherwise I can choose a flavour I enjoy without assuming that flavoured water and tonic have the same formulation. |
Tonic and soda can differ substantially. Fentimans lists no sugar for its Soda Water but 4.4g sugar for its Premium Indian Tonic Water; Tesco lists 3.3g sugars per 100ml for its Indian Tonic Water.
Compare the current nutrition panel and ingredients for the exact drink, then consider the amount you will have.
A sparkling drink does not replace a plan for food and fluids when another demanding session follows soon. The British Dietetic Association advises prompt carbohydrate-rich foods and fluids when quick recovery is required.
Choose the drink for its fluid and flavour, and consider your food separately when the session calls for refuelling.
For choices involving sugar, sweeteners or particular ingredients, the formulation of the variety in your hand is what matters.
Check the bottle or can for its current ingredients and nutrition information before buying or drinking it.

Yes, if you enjoy it and are comfortable drinking it after exercise. The NHS identifies water as the preferred way to replace lost fluid. When quick recovery for another demanding session is needed, the British Dietetic Association also advises carbohydrate-rich foods and fluids.
No. Tonic is a flavoured mixer, and its ingredients and sugars can differ from plain sparkling water. Fentimans lists sugar in its Premium Indian Tonic Water, so choose tonic for its taste and check the particular label rather than assuming it is equivalent to water.
Do not rely on a sparkling mixer alone for quick refuelling. The British Dietetic Association advises starting carbohydrate-rich foods and fluids as soon as possible after exercise when quick recovery is required.
