Shoppers planning exercise
If you want a bottled drink for a gym session or training, check whether the label describes a still isotonic drink rather than assuming a fizzy drink serves the same purpose.
Who is choosing?
The useful starting point is whether the drink is for everyday thirst, planned exercise or a format you can prepare yourself.
Everyday shoppers who like fizz
If you mainly want something sparkling for ordinary hydration, sparkling water is an option the NHS suggests for people who do not like plain water. Check flavoured drinks for sugar and caffeine separately.
Shoppers choosing a cupboard or travel format
Sachets take a different approach from ready-to-drink bottles: you need water, a suitable bottle and the product’s mixing instructions before you have a prepared drink.
What should you check?
Decide what the drink is for before comparing formats. Then use the label to compare the amount you would actually drink, not just a highlighted serving figure.
Water or sparkling water
Choose when: You want a drink for ordinary hydration; the NHS suggests sparkling water if you prefer fizz.
Bear in mind: Water is not a like-for-like carbohydrate-electrolyte sports-drink formulation.
Still isotonic bottle
Choose when: You want a prepared carbohydrate-electrolyte drink for planned exercise.
Bear in mind: The Tesco-listed Lucozade Sport Orange and Powerade Berry & Tropical examples contain sugars; check the quantity you plan to drink.
Drink-mix sachet
Choose when: You would rather carry or store a sachet and prepare the drink with your own water.
Bear in mind: It is not ready to drink. Sainsbury's lists Gatorade Hydration Booster as one 13.5g sachet mixed with 500ml water.
Sparkling energy drink
Choose when: You intentionally want that type of fizzy drink, rather than an isotonic sports drink.
Bear in mind: Tesco describes Lucozade Energy Orange as a sparkling glucose drink and lists caffeine; fizz alone says nothing about whether a drink is isotonic.
| Priority | What to check | Your needs |
|---|---|---|
| Purpose | Read the product description for water, isotonic sports drink or energy drink. Check ingredients if you want to distinguish a carbohydrate-electrolyte formulation from a sparkling glucose drink. | I am buying mainly for everyday drinks, so water or sparkling water may fit. If I want a formulated drink for planned exercise, I will choose that deliberately rather than by its position on the shelf. |
| Fizz | Check whether the exact product is described as sparkling or still. Tesco labels Powerade Berry & Tropical still and isotonic, but Lucozade Energy Orange sparkling. | Fizz matters to me, but I do not want to mistake carbonation for a sports-drink specification. |
| Nutrition | Compare sugars, carbohydrate and salt on the same basis: per 100ml, then per bottle or prepared amount. Tesco lists 18.0g sugars per 500ml Lucozade Sport Orange bottle and 9.8g per 250ml Powerade Berry & Tropical serving; Sainsbury's lists 11g per prepared 500ml Gatorade Hydration Booster serving. | I want the figures for the amount I expect to drink, not a comparison between differently sized portions. |
| Preparation | Check whether the drink is ready to consume or needs mixing. For Gatorade Hydration Booster, Sainsbury's specifies one 13.5g sachet with 500ml water; check the directions for any other powder separately. | A bottle suits me when I cannot prepare a drink. A sachet works when I will have water and a bottle available. |
Common shopping mistakes
-
Choosing by fizz instead of drink type
Tesco describes Lucozade Energy Orange as a sparkling glucose drink with caffeine, while its Powerade Berry & Tropical listing describes a still isotonic sports drink. They are not interchangeable descriptions.
Decide whether you want everyday hydration, an isotonic product or a sparkling energy drink, then check the exact pack description and ingredients.
-
Comparing different serving sizes as though they match
Tesco gives sugar figures for a 500ml Lucozade Sport Orange bottle and a 250ml Powerade Berry & Tropical serving. Sainsbury's gives Gatorade Hydration Booster figures for a prepared 500ml drink.
Compare per 100ml where available, then check the figures for the full amount you expect to consume.
-
Picking a sachet without planning how to mix it
A powder needs water and a suitable container before it becomes a drink. Sainsbury's directions for Gatorade Hydration Booster specify one 13.5g sachet mixed with 500ml water.
Choose that format only when you can follow its preparation directions; otherwise consider a ready-to-drink option or water.
-
Buying a sports drink for routine thirst by default
The NHS identifies water as the way to replace lost fluids and suggests sparkling water for people who prefer it. The Tesco-listed isotonic examples contain sugars, which remain relevant when choosing everyday drinks.
Keep the drink’s intended occasion in mind and read the nutrition label before adding it to a regular food shop.
Brand and format references
These product-line examples help distinguish bottles from sachets; the figures apply to the named products and serving sizes, not every drink from each brand.
Lucozade Sport
Tesco lists Lucozade Sport Orange as a bottled isotonic drink. Do not confuse the Sport range with the separately listed sparkling Lucozade Energy Orange.
- The Tesco-listed Lucozade Sport Orange 500ml bottle contains 18.0g sugars.
- The bottle’s nutrition figures should be considered for the amount you plan to drink, rather than treated as a reason to choose a sports drink for routine thirst.
Powerade
Tesco describes Powerade Berry & Tropical 500ml as a still isotonic sports drink.
- Its Tesco listing states 3.9g carbohydrate and 3.9g sugars per 100ml.
- The highlighted 9.8g sugar figure is for a 250ml serving, not the full 500ml bottle.
Gatorade
Sainsbury's lists Gatorade Hydration Booster Cherry Lime as powder sachets to be mixed with water.
- The listed directions specify one 13.5g sachet mixed with 500ml water.
- The stated 11g sugars and 1g salt apply to the prepared 500ml drink; the sachet is not ready to drink on its own.
Joybuy drink options
These options include bottled electrolyte drinks, a sparkling energy drink and a powder to mix with water. Check each product’s description for the format you want: a sparkling energy drink is not presented here as a substitute for an isotonic sports drink.

DP Electrolyte Drink Lemon Flavour 555ml
This 555ml bottle is a ready-to-drink electrolyte option. If you specifically need a sparkling or isotonic product, check both descriptions on its pack rather than assuming either from the name. The listing advises consuming it immediately after opening.
Frequently asked questions
Is a sparkling drink the same as a still isotonic sports drink?
No: carbonation does not establish that a drink is isotonic. Tesco describes Powerade Berry & Tropical as still and isotonic, but Lucozade Energy Orange as a sparkling glucose drink containing caffeine. Check the description of the exact product you are considering.
What if I just want a fizzy drink for everyday hydration?
The NHS suggests sparkling water if you do not like plain water. For a flavoured fizzy drink, check its ingredients and nutrition label rather than assuming it has the same contents as sparkling water.
How do I compare sugar when bottle and serving sizes differ?
Start with the per-100ml figures where available, then compare the amount you would drink. Tesco lists 18.0g sugars per 500ml Lucozade Sport Orange bottle and 9.8g per 250ml Powerade Berry & Tropical serving; Sainsbury's lists 11g per prepared 500ml Gatorade Hydration Booster serving. Those serving sizes are not identical.
Are sports-drink powder sachets ready to drink?
No. Sainsbury's instructions for Gatorade Hydration Booster specify mixing one 13.5g sachet with 500ml water; its listed drink nutrition applies to that prepared amount. Follow the directions on whichever powder you choose.
What should I check on a pre-packed drink label?
Check the ingredients, allergen information, nutrition figures and stated serving size on the pack. UK government food-labelling guidance covers ingredients and nutrition information for pre-packed foods; for this choice, the product description also matters because it distinguishes drinks labelled still, sparkling or isotonic.
