Choose a sparkling drink for the fizz, but check its carbohydrate content before treating it as exercise fuel: Cadence Core Hydration cans are zero sugar, while Tesco lists 6.3g carbohydrate per 100ml for still Lucozade Sport Orange, an option for prolonged endurance exercise. If you simply want a drink alongside a gym-bag snack, NHS guidance recommends water for replacing fluid lost through physical activity.
Whether you want fizz, exercise fuel or simply something to drink with a snack changes which label details matter.
If you want a carbonated drink and do not need carbohydrate during your session, a sparkling zero-sugar electrolyte drink is one option. Cadence describes its Core Hydration cans as carbonated and zero sugar; consider whether fizz feels comfortable when you exercise.
If you want carbohydrate alongside fluid and electrolytes, check a drink’s nutrition label rather than choosing by carbonation alone. Tesco lists Lucozade Sport Orange as an isotonic drink with 6.3g carbohydrate and 50mg sodium per 100ml.
A routine visit does not, by itself, call for an exercise-fuelling drink. NHS guidance recommends water for replacing fluid lost through physical activity. If you choose a packaged drink instead, check whether it is a sports drink or a caffeinated energy drink.
Decide whether the drink is for ordinary hydration, a preference for fizz or carbohydrate during prolonged exercise. Then compare the current pack’s format and nutrition information.
| Priority | What to check | Your needs |
|---|---|---|
| Fizz and format | Look for an explicit carbonated or sparkling description. Check whether it is a ready-to-drink can, a bottle or a product you mix with water. | I want fizz without having to prepare a drink at the gym. I would check the format rather than assume every sports drink is sparkling. |
| Carbohydrate | Read carbohydrate and sugars per 100ml, not just the word ‘electrolyte’. Tesco lists 6.3g carbohydrate and 3.5g sugars per 100ml for Lucozade Sport Orange; Cadence describes its Core Hydration cans as zero sugar. | For prolonged endurance activity, I may want carbohydrate as well as fluid. For a routine visit, I may prefer a drink without carbohydrate fuel. |
| Electrolytes | Compare named minerals and their amounts using the same serving basis. Cadence states 500mg sodium, 190mg potassium and 30mg magnesium per Core Hydration can; Tesco lists 50mg sodium per 100ml for Lucozade Sport Orange. | If I am choosing a drink for its electrolytes, I want to know which ones it contains and how the label measures them. |
| Caffeine and drink type | Check the product description and ingredients for caffeine and for an isotonic or carbohydrate-electrolyte formulation. Tesco lists carbonated water and caffeine in Lucozade Energy Original, separately from Lucozade Sport Orange. | I do not want to mistake a fizzy energy drink for the sports drink I meant to pack. |
| Drinking comfort | If fizz bothers you during exercise, try a carbonated drink in a routine session before relying on it for a longer one. Still water or a still sports drink offers another format. | I enjoy fizz, but I want a drink I am comfortable having during the activity I have planned. |
| Pack size and label | Check the container size, serving information, ingredients and any relevant pack warnings. Compare nutrition figures on the same per-100ml or per-serving basis. | I need a container that fits my gym bag and label information that matches what I intend to drink. |
Fizz does not identify a drink’s purpose. Tesco lists carbonated water and caffeine in Lucozade Energy Original, while it describes Lucozade Sport Orange separately as an isotonic carbohydrate-and-electrolyte drink.
Check the product description, ingredients and nutrition label for the formulation you actually want, including caffeine, carbohydrate and electrolytes.
Cadence describes its sparkling Core Hydration cans as zero sugar. They are not interchangeable with a drink selected for its carbohydrate content, such as the Lucozade Sport Orange product listed by Tesco.
Decide whether you want carbohydrate for your planned activity before choosing between a zero-sugar electrolyte drink and a carbohydrate-containing sports drink.
A small study of 15 people cycling, published in the International Journal of Sport Nutrition and Exercise Metabolism, found no effect of carbonation on gastric emptying. That finding is not a reason to expect a sparkling drink to work faster.
Choose fizz because you like it, and try it during a routine session before taking it to a long or important workout. Use a still drink if carbonation feels uncomfortable.
The drink name alone does not tell you its full ingredient list, nutrition per serving or pack warnings. Those details matter when comparing drinks that serve different purposes.
Check the pack you intend to buy for carbonation, caffeine, carbohydrate, sugars, sodium, ingredients and serving size.
These examples help distinguish drink types; a brand name alone does not establish whether a particular product is sparkling or suitable for your session.
Cadence describes its Core Hydration cans as carbonated, zero sugar and containing electrolytes.
Tesco lists Lucozade Sport Orange as an isotonic drink with carbohydrate and electrolytes for prolonged endurance exercise.
Gatorade UK describes Hydration Booster as a carbohydrate-and-electrolyte drink mix.
Tesco lists Powerade multipacks in its UK sports-drinks category, including Golden Mango and Berry & Tropical Fruits varieties.
These options cover carbonated drinks for a gym bag and a still isotonic alternative when carbohydrate matters more than fizz. Compare each pack’s label with your intended use.

A 325ml carbonated isotonic drink for someone looking for fizz in a gym-bag format. Check the current pack’s carbohydrate, sugars, electrolytes, caffeine information and ingredients against what you need.

A carbonated, zero-sugar electrolyte option if you want fizz without carbohydrate fuel. The pack contains 12 x 330ml cans. Check the current can label if you need to compare individual electrolyte amounts, and try fizz during a routine session if drinking comfort is a concern.

A still isotonic alternative for prolonged endurance activity when carbohydrate as well as electrolytes is relevant. The pack contains 12 x 500ml bottles. Tesco lists 6.3g carbohydrate, 3.5g sugars and 50mg sodium per 100ml for Lucozade Sport Orange; check the current bottle label, including its ingredient warnings, before use.
No: carbonation alone does not tell you what else a drink contains. Tesco lists caffeine in Lucozade Energy Original, whereas it describes Lucozade Sport Orange separately as an isotonic carbohydrate-and-electrolyte drink. Check the specific drink’s ingredients and nutrition label.
Consider a carbohydrate-containing isotonic drink when you want carbohydrate alongside fluid and electrolytes for prolonged endurance exercise. Tesco lists 6.3g carbohydrate per 100ml for Lucozade Sport Orange; Cadence describes its sparkling Core Hydration cans as zero sugar, so they meet a different fuelling need.
Do not choose fizz on that assumption. A study of 15 people cycling, published in the International Journal of Sport Nutrition and Exercise Metabolism, found no effect of carbonation on gastric emptying. Choose a sparkling drink if you enjoy it and find it comfortable during your activity.
No. NHS guidance recommends water for replacing fluid lost through physical activity. Choose a packaged sports drink for a specific feature you want, such as carbohydrate for prolonged endurance activity, rather than simply because you are taking a snack to the gym.
