For a lecture lunch without exercise, NHS guidance points to water, including sparkling water if you prefer fizz; a caffeine-free sparkling hydration drink is another choice if you want its flavour. If you are buying for prolonged exercise, consider a still isotonic drink instead, and check sugars and caffeine before treating any fizzy drink as sports hydration.
For a lunch between lectures, compare plain sparkling water with a drink explicitly labelled caffeine-free. If you choose a flavoured hydration drink, check its sugars per 100ml rather than assuming its electrolyte label tells you what is in it.
If you are also buying for prolonged exercise or a session involving substantial sweating, consider whether a still carbohydrate-electrolyte sports drink suits that activity. It will not satisfy a preference for fizz at lunch.
Fizz and electrolytes do not rule out caffeine. Read the caffeine statement as well as the nutrition panel if you want a lunch drink rather than a caffeinated energy drink.
Decide whether the drink is for lunch or exercise, then check carbonation, caffeine and the per-100ml nutrition panel.
| Priority | What to check | Your needs |
|---|---|---|
| Fizz and caffeine | Check that the drink is carbonated and read its caffeine statement. Tesco lists the sparkling Tenzing energy drink with 32mg caffeine per 100ml and a high-caffeine warning, despite its electrolyte content. | I want fizz with lunch, but I do not want to choose a caffeinated energy drink by mistake. |
| Exercise fit | Check whether the drink is intended for exercise and whether it contains carbohydrate and electrolytes. Coca-Cola GB describes Powerade as a still isotonic sports drink; Tesco describes Lucozade Sport Orange as intended for prolonged endurance exercise. | For a seated lecture, I want a drink for ordinary refreshment. If I am training afterwards, I may also need to choose for that session. |
| Sugars | Compare sugars per 100ml, then consider how much you will drink. Sainsbury's lists Punchy Mexican Lime at 2.7g, Tesco lists Lucozade Sport Orange at 3.5g, and Coca-Cola GB lists Powerade Berry & Tropical Fruits at 4.1g per 100ml. | I want to compare a flavoured lunch drink with an exercise drink on the same nutrition basis, not just by the wording on the front of the pack. |
| Ready to drink | Check the format and any preparation needed. Sainsbury's lists Punchy Mexican Lime in 330ml cans; Gatorade UK instructs shoppers to mix one Hydration Booster sachet with 500ml water. | A ready-to-drink can suits a short break; a sachet is practical for me only if I can carry water and mix it. |
Carbonation describes fizz, not caffeine content or whether a drink is intended for exercise. Tesco's sparkling Tenzing energy drink, for example, lists electrolytes alongside a high-caffeine warning.
Decide whether you want an ordinary lunch drink, exercise fuelling or caffeine, then check the carbonation, caffeine and nutrition information.
The reviewed Powerade and Lucozade Sport drinks are positioned for physical exercise. NHS guidance identifies water as an everyday hydration choice and suggests sparkling water for people who prefer it.
If lunch is not connected to a workout, start with the drink you want for that break. Consider a sports drink separately if you are also choosing for exercise.
Drinks described as hydration or sports products can list different sugar amounts. Comparing packs of different sizes without using the same measure can obscure that difference.
Read sugars per 100ml on each pack, then account for the amount you expect to drink.
The reviewed Orange drink is an isotonic option marketed for prolonged endurance exercise, rather than a sparkling lecture-lunch drink.
Coca-Cola GB describes Powerade as a still isotonic sports drink for physical exercise.
Gatorade Hydration Booster is a sachet to mix with water, not a ready-to-drink sparkling option.
The reviewed Mexican Lime drink is a sparkling, caffeine-free option for shoppers whose lunch preference is fizz.
This carbonated isotonic drink fits a preference for fizz in a ready-to-drink format. If avoiding caffeine matters for lunch, check its current pack label before choosing it.

The 325ml carbonated isotonic format suits a preference for fizz. For a routine lecture lunch, compare sugars per 100ml with other drinks and check the current label for caffeine if you want to avoid it.
No. Coca-Cola GB describes Powerade as still, and the reviewed Lucozade Sport drinks are not presented as sparkling options. If fizz is essential, check that the particular drink is labelled carbonated.
Attending lectures alone is not a reason to choose an exercise drink. NHS guidance identifies water as an everyday hydration choice and suggests sparkling water if you prefer fizz; consider an exercise-specific drink separately if you are also buying for prolonged activity or sweating.
Yes. Tesco lists its sparkling Tenzing energy drink as containing electrolytes and 32mg caffeine per 100ml, with a high-caffeine warning. Read the caffeine statement rather than relying on fizz or electrolyte wording to identify the drink type.
Use sugars per 100ml before comparing the amount in different pack sizes. Sainsbury's lists Punchy Mexican Lime at 2.7g, Tesco lists Lucozade Sport Orange at 3.5g, and Coca-Cola GB lists Powerade Berry & Tropical Fruits at 4.1g per 100ml; check the current pack label before buying.
