For a short, light-to-moderate gym session, water is usually sufficient for replacing fluid, according to NHS and Loughborough University guidance; choose no-added-sugar squash or cordial if you prefer a flavoured drink alongside your snack. After harder or longer exercise, consider food and electrolyte needs separately rather than treating cordial as recovery nutrition. Compare calories and sugars per diluted serving, then check the ingredients and mixing instructions.
If you want flavour with your post-gym snack, compare calories and sugars in the diluted drink rather than judging a concentrate by its bottle size. Loughborough University says water should be sufficient for short periods of light-to-moderate exercise.
A no-added-sugar squash can accompany food, but it does not replace a protein-containing snack or meal. University College London Hospitals describes carbohydrate-and-protein snacks as an option around exercise.
Choose the drink in the context of the session, not just its flavour. Loughborough University advises considering electrolytes for exercise lasting more than 60 minutes; a cordial should not be assumed to provide them.
Start with what the session calls for, then compare drinks as prepared: concentrates can have different dilution ratios and serving sizes.
| Priority | What to check | Your needs |
|---|---|---|
| Fluid and recovery | Consider session length and intensity. Check food separately for carbohydrate and protein, and assess electrolytes for longer or hot sessions. | For a short, moderate workout, I want a drink with my snack, not a substitute for it. NHS and Loughborough University guidance identifies water as sufficient for ordinary short sessions. |
| Prepared nutrition | Compare calories and sugars on each label’s diluted-serving basis. Follow its stated dilution ratio before using those figures. | I want to know what is in the glass I actually drink. Tesco Groceries lists Robinsons Orange No Added Sugar at 3 kcal and 0 g sugars per 250 ml diluted serving, while its Tesco Quadruple Strength Blackcurrant lists 3 kcal and 0.4 g sugars per 300 ml glass; those are different serving sizes. |
| Ingredients | Read the sweeteners, fruit ingredients and allergen declaration on the exact bottle. A no-added-sugar claim does not mean zero sugars. | If I avoid a particular ingredient, flavour alone will not settle the choice. Tesco Groceries lists barley in Vimto No Added Sugar and 0.8 g sugars per 250 ml prepared serving. |
| Mixing and storage | Check the concentrate-to-water ratio, serving definition and instructions after opening. Do not apply one bottle’s prepared nutrition to a stronger mix. | I would rather choose a bottle I can prepare and finish as directed. Tesco Groceries gives a 1:4 concentrate-to-water ratio for Robinsons Orange and 1:19 for Tesco Quadruple Strength Blackcurrant; follow the instructions on the product you buy. |
A flavoured drink does not take the place of food when the session calls for carbohydrate or protein. University College London Hospitals describes carbohydrate-and-protein snacks for use around exercise.
Plan the snack and drink separately, particularly after demanding or resistance-focused exercise.
Different serving sizes and dilution ratios make bottle volume a poor substitute for a per-glass nutrition check.
Use each label’s mixing instructions, then compare the calories and sugars for the amount you intend to drink.
A no-added-sugar drink may still contain sugars from its ingredients, as well as sweeteners or allergens. Tesco Groceries lists sugars in prepared Vimto No Added Sugar and identifies barley in its ingredients.
Read the nutrition, ingredients and allergen information on the exact bottle, especially if you avoid specific sweeteners, sulphites or barley.
Storage and opened-bottle use periods can affect whether a cordial suits how often you drink it.
Check the purchased bottle’s refrigeration and use-after-opening instructions before choosing a size.
An opened bottle that cannot be finished within its stated period may go to waste.
These examples show different squash and cordial formulations; compare the exact product label rather than assuming a brand’s whole range has the same nutrition or ingredients.

A blackcurrant concentrate for a flavoured drink alongside food. Its listing presents conflicting calorie information, so check the current bottle’s nutrition panel and whether figures refer to concentrate or diluted drink before using them for a per-glass comparison. Check the ingredients if sweeteners or sulphites are a concern.
No: treat it as a drink alongside food, not as the snack itself. University College London Hospitals describes carbohydrate-and-protein snacks for use around exercise, so plan food separately when your session calls for it.
For short, light-to-moderate exercise, water should be sufficient for fluid replacement, according to Loughborough University; the NHS also recommends water for replacing fluid lost through activity. Cordial is a flavour choice in that situation, not a requirement.
No. Tesco Groceries lists 0.8 g sugars per 250 ml prepared serving of Vimto No Added Sugar, and Waitrose & Partners lists 0.4 g per 100 ml diluted Belvoir Lemon & Lime No Added Sugar Cordial. Read the nutrition values for the drink as prepared.
Consider the session and your food as well as the drink. Loughborough University advises considering electrolytes for exercise lasting more than 60 minutes, while University College London Hospitals describes carbohydrate-and-protein snacks around exercise. Do not assume an ordinary cordial supplies either.
Read the ingredients and allergen declaration on the exact bottle. Tesco Groceries identifies barley in the cited Vimto No Added Sugar squash, while the cited Belvoir cordial uses steviol glycosides from stevia; formulations differ even within the no-added-sugar category.
