Gym-goers who want a fizzy drink afterwards
A fizzy drink can be a separate treat, but it should not take the place of workout water. The NHS recommends water for replacing fluid lost through physical activity.
Who is this choice for?
Shoppers considering a glass bottle
If you like the bottle format, consider how you will protect it on the journey and whether your gym permits glass. Your Coca-Cola UK lists Coca-Cola Original Taste in 330ml glass bottles; check the format of any other drink individually.
Shoppers comparing sugar on the label
Compare the nutrition panel on the precise drink and pack you intend to carry. A brand name and a 330ml size do not establish that a glass bottle has the same formulation as a standard can.
What should you check before packing a drink?
Start with water for the workout, then decide whether a separate fizzy drink suits your journey, the venue and your preference for sugar content.
| Priority | What to check | Your needs |
|---|---|---|
| Workout fluids | Pack water for exercise and consider extra fluids after sweating, in line with NHS guidance. Keep any fizzy drink separate from that purpose. | I need a drink for the workout itself, not just something fizzy to have afterwards. |
| Carrying glass | Check the gym's container rules. If you choose glass, consider whether you can keep the bottle protected and upright in your bag. | Will my bag and journey make a glass bottle practical, or would I rather carry a non-glass drink? |
| Sugars | Compare the exact pack's sugars per 100ml and per serving, keeping the serving size in view. Pepsi UK lists 15g per standard 330ml serving, while Regency Foods lists 36g for a separately sold 330ml Pepsi glass bottle. | I want to know what is in the bottle or can I will actually drink, rather than relying on another pack's label. |
| Everyday choice | Check how often you choose a sugary drink as well as its sugar figure. The NHS links having too much sugary food and drink with tooth decay. | A fizzy drink might be an occasional treat for me; I want a separate routine drink for the gym. |
Gym-bag drink mistakes to avoid

Relying on fizzy drink for workout fluids
A drink chosen as a treat serves a different purpose from replacing fluid lost through exercise. The NHS recommends water for that fluid replacement.
Put water in your bag first, then decide whether you also want a fizzy drink for afterwards.
-
Using a can's figures for a glass bottle
Pepsi UK lists 15g sugars for its standard 330ml serving, whereas Regency Foods lists 36g for a separately sold 330ml Pepsi glass bottle. The shared brand and volume do not make those labels interchangeable.
Read the nutrition panel and ingredients on the exact pack before comparing it with another drink.
-
Assuming glass will work at the gym
A glass bottle needs suitable protection in a moving bag, and whether it can be taken into a gym depends on that venue's rules.
Check the gym's container policy before travelling. If carrying glass is impractical, choose a non-glass container.
Brands and label references
Use these product-specific references to compare formulations; a brand's presence here does not establish the packaging of every drink it sells.
Coca-Cola
Your Coca-Cola UK lists Coca-Cola Original Taste in a 24-pack of 330ml glass bottles.
- Coca-Cola GB lists 10.6g sugars per 100ml for Original Taste.
- The availability of a Coca-Cola glass bottle does not establish equivalent glass formats for Sprite, Fanta or Dr Pepper.
Pepsi
Check the particular Pepsi pack rather than treating a standard UK product and a separately sold glass bottle as the same formulation.
- Pepsi UK lists 15g sugars per standard 330ml serving and sweeteners in its ingredients.
- Regency Foods lists 36g sugars for a separately sold 330ml Pepsi glass bottle.
Sprite
Sprite and Sprite Zero give shoppers two different sugar figures to compare on the precise product label.
- Coca-Cola GB lists 4.4g sugars per 100ml for Sprite and 0g per 100ml for Sprite Zero.
- Check the selected product's sweetener and phenylalanine information, as well as its packaging format.
Fanta
Fanta Orange is a fruit-flavoured option to assess by its own label rather than a cola's figures.
- Coca-Cola GB describes Fanta Orange as caffeine free and lists 4.5g sugars per 100ml.
- The listed formulation contains sweeteners; check the exact variant and pack before buying.
Tesco
Tesco is a retailer whose product pages can help you inspect serving information; it is not a fizzy-drink brand in this comparison.
- Its Pepsi 330ml listing gives nutrition per serving.
- Tesco advises shoppers to read the product label because food products can be reformulated.

Gym-bag fizzy drink FAQs
Should I use a glass-bottle fizzy drink for workout hydration?
Pack water for workout hydration: the NHS identifies it as the way to replace fluid lost through physical activity. If you also want a glass-bottle fizzy drink afterwards, check that you can carry it securely and that your gym permits glass.
How should I compare sugar across fizzy drinks?
Read the nutrition panel on the exact product and compare equivalent amounts, such as sugars per 100ml, as well as the amount in the serving you will drink. Pepsi UK lists 15g sugars for its standard 330ml serving, while Regency Foods lists 36g for a separately sold 330ml Pepsi glass bottle, so do not transfer a can's figures to a bottle.
Does having a sugary fizzy drink after the gym matter if I do it often?
Frequency matters as well as the sugar figure on the label: the NHS links having too much sugary food and drink with tooth decay. Keep water as your routine workout drink and check the label when choosing a separate fizzy drink.
