Gym-goers wanting a fizzy drink afterwards
A small tonic may appeal after a session, but it serves a different purpose from the water used to replace fluid lost through exercise. The NHS recommends water for replacing those lost fluids.
Who is this choice for?
Shoppers choosing a lower-sugar 12-pack
If you want twelve 150ml portions, compare the two Schweppes formulations rather than choosing by pack size alone. The Slimline listing states 0g sugar per 100ml and identifies aspartame and a source of phenylalanine.
People carrying mixers for later
If the gym bag is just how you transport a drink for a later serve, the individual portion and tonic style may matter more than exercise use. Consider how many portions you need to carry rather than assuming the whole case belongs in the bag.
What should you check?
Start with when you plan to drink it. If the tonic is for later, compare the formulation and the quantity you intend to carry.
| Priority | What to check | Your needs |
|---|---|---|
| Exercise hydration | Decide whether the drink is meant to replace fluid lost through sweating or to be an occasional flavoured drink. The NHS identifies water as the best way to replace fluid lost through physical activity. | I need something to drink during or after exercise to replace lost fluid, so I will take water first. A tonic would be for its flavour or later mixer use. |
| Ingredients and nutrition | Compare the label per 100ml. Joybuy lists Schweppes Slimline at 2 kcal and 0g sugar, and Schweppes Indian Tonic at 21 kcal; Slimline contains aspartame and a source of phenylalanine. | If I prefer the zero-sugar formulation, I need to check Slimline’s sweetener information too. If I want the regular tonic formulation, I should read its ingredients rather than assuming the two cases are interchangeable. |
| Pack and carrying | Confirm the 12 × 150ml format, which contains 1.8L of drink in total. Check the current packaging description and your bag space before planning to carry the whole case. | One portion may be enough for my trip; I can keep the rest elsewhere. For Schweppes Indian Tonic, I also need to confirm whether the individual units are cans or bottles before choosing how to pack them. |
What is easy to overlook?
-
Treating tonic as a gym snack or hydration plan
A mixer’s small serving size does not make it the drink to rely on for replacing fluid lost through exercise. The NHS recommends water for that purpose.
Pack water for the session. Bring tonic separately if you want its flavour afterwards or need it as a mixer later.
-
Assuming Slimline differs only in sugar
Joybuy’s Schweppes Slimline listing also identifies aspartame and a source of phenylalanine. The regular Indian Tonic lists sugar and sodium saccharin.
Read the current ingredient list and nutrition panel, particularly if either sweetener or phenylalanine matters to your choice.
-
Confusing individual portions with a portable case
Twelve 150ml portions contain 1.8L of drink before accounting for their packaging or anything else in your bag.
Check your bag space and take only the portions needed for the trip. Confirm the unit packaging for the regular Schweppes case before buying it for bag use.
Which brands are relevant?
Schweppes
The Slimline and Indian Tonic products considered here both come in a 12 × 150ml format, according to Tesco and Joybuy listings.
- Joybuy lists the Slimline product at 2 kcal and 0g sugar per 100ml, compared with 21 kcal per 100ml for the Indian Tonic product.
- Slimline contains aspartame and a source of phenylalanine; confirm the regular product’s can-or-bottle packaging if that affects how you will carry it.
Fever-Tree
Fever-Tree offers tonic cans that the brand describes as convenient to take out, making the range worth considering when an exact 12-pack is not essential.
- Tesco lists a Fever-Tree light tonic multipack in a 15 × 150ml format.
- Check the pack count before choosing it for a requirement of exactly twelve portions.
Fentimans
Fentimans provides a tonic and a soda-water alternative for shoppers considering different mixer styles rather than only an exact 12-pack.
- Fentimans lists its Premium Indian Tonic at 20 kcal and 4.4g sugar per 100ml, and its Soda Water at 0 kcal and 0g sugar per 100ml.
- The product information describes 200ml formats; check the quantity and pack size if twelve 150ml portions are required.
Britvic
Britvic discusses lower- and no-calorie drinks across its wider portfolio, rather than a particular 12 × 150ml tonic case.
- Britvic says 98% of its owned drinks made and sold in Great Britain and Ireland are low or no calorie.
- That company-wide figure does not tell you the ingredients, nutrition or pack format of an individual mixer.

Common questions
Can tonic water replace the water I take to the gym?
Use water as your main drink for replacing fluid lost through physical activity; the NHS identifies it as the best way to do so. A tonic can serve as an occasional flavoured drink or a mixer for later, not the reason to leave your water behind.
How do the two Schweppes 12 × 150ml cases differ?
Joybuy lists Slimline Tonic Water at 2 kcal and 0g sugar per 100ml, and Indian Tonic Water at 21 kcal per 100ml. Slimline contains aspartame and a source of phenylalanine; the Indian Tonic ingredient list includes sugar and sodium saccharin.
How much drink is in a 12 × 150ml case?
The twelve portions contain 1.8L of drink in total. That does not tell you whether the packed case will fit your gym bag, so check the available space and consider carrying only the portions you need.
What should I check on the pack before buying?
Check the current ingredients, nutrition per 100ml, net quantity and date marking for the product you choose. Pay particular attention to Slimline’s aspartame and phenylalanine information, and confirm the individual packaging of the regular Indian Tonic if cans or bottles would make a difference to your trip.
