Gym-goers planning a smoothie with a meal
Portion size matters if you also drink fruit or vegetable juice. The NHS advises a combined limit of 150ml a day for juice and smoothies, so a larger bottle need not be treated as one serving.
Who is this choice for?
The right format depends on when you will drink it, how long it will be in your bag and whether you specifically want a smoothie.
People carrying a drink from home
Check the storage instructions for the exact pack and the time it will spend in your bag. Waitrose & Partners lists an out-of-fridge allowance for one innocent children’s pouch; Tesco Groceries instructs shoppers to refrigerate an innocent 250ml bottle at 0–8°C.
Shoppers avoiding added sugar or sweeteners
Read the ingredients as well as the no-added-sugar wording. Fruit smoothies can still contain naturally occurring sugars, while some no-added-sugar juice drinks contain sweeteners.
What should you check before buying?
Start with the drink type and pack size, then check its sugar information and storage directions against your journey.
| Priority | What to check | Your needs |
|---|---|---|
| Sugar wording | Compare the no-added-sugar claim with sugars per 100ml and the amount you plan to drink. Read the ingredients if you want to avoid sweeteners. | I want to know what is in the drink, rather than treating “no added sugar” as “sugar-free”. |
| Portion size | Check the pack volume and whether you can portion a larger bottle. The NHS advises limiting fruit juice and smoothies together to 150ml a day. | A 150ml pack makes that amount straightforward; if I buy 250ml or more, I need to decide how much I will drink. |
| Storage | Read the exact pack’s refrigeration and unopened-storage instructions. Waitrose & Partners states that the innocent 150ml children’s pouch lasts up to 12 hours out of the fridge; Tesco Groceries says to keep the innocent 250ml bottle at 0–8°C. | My drink may sit in a gym bag during travel and a workout, so I need storage instructions that fit that plan. |
| Drink type | Check whether the label says smoothie or juice drink, and compare ingredients if oats, seeds or sweeteners matter to you. | If I specifically want a fruit smoothie, an ambient juice drink is not an interchangeable purchase, even when both say no added sugar. |
Common buying mistakes
-
Reading “no added sugar” as “sugar-free”
A smoothie made with fruit can contain sugars even when none has been added. The no-added-sugar wording alone does not tell you the amount in your portion.
Read sugars per 100ml on the nutrition panel and compare it with the volume you expect to drink. Check the ingredients separately for sweeteners.
-
Treating a large bottle as one routine portion
A 250ml bottle or 750ml carton is larger than the NHS’s combined 150ml daily limit for fruit juice and smoothies.
Choose a pack size you can portion, or plan how you will store the remainder in line with its label.
-
Applying one pack’s storage allowance to another
Waitrose & Partners lists up to 12 hours out of the fridge for an innocent 150ml children’s pouch, while Tesco Groceries says the innocent 250ml bottle must be kept at 0–8°C. The pouch statement does not cover the bottle.
Follow the instructions on the pack you buy. If it must stay chilled, plan how you will keep it within those instructions while carrying it.
-
Buying a juice drink when you wanted a smoothie
An ambient drink may suit a journey without chilled storage, but its label and ingredients can differ from those of a fruit smoothie. Tesco Groceries describes its no-added-sugar pineapple-and-coconut option as a juice drink with sweetener.
Decide whether the drink must be a smoothie before comparing portable alternatives.
Brand and product-line references
These examples show why the exact drink and pack format matter more than a brand name alone.
innocent
Its listed fruit smoothies include a 150ml children’s pouch and a 250ml chilled bottle, both relevant to a no-added-sugar comparison.
- Waitrose & Partners states that the 150ml children’s pouch lasts up to 12 hours out of the fridge.
- Tesco Groceries says the 250ml strawberries-and-bananas bottle must be kept at 0–8°C. Do not apply the pouch’s storage allowance to it.
Tesco
Its no-added-sugar pineapple-and-coconut juice drink is an alternative to consider when an ambient drink is acceptable.
- Tesco Groceries describes an unopened pack that stores in a cool, dry place.
- It is a juice drink rather than a smoothie, and its ingredient description includes sweetener.
M&S
Revitalise Super Smoothie is an example to inspect if ingredients such as oat drink and linseed interest you.
- Marks & Spencer lists 3.6g fibre per 100g for this product.
- Its listing specifies refrigeration at 0°C to +5°C. Check the current pack if no added sugar is a requirement.
Naked
Green Machine comes in a 750ml format, making portion size a consideration for this gym-bag question.
- Tesco Groceries lists 8.8g sugars and 0g fibre per 100ml, giving shoppers figures to compare with their intended portion.
- Check the current pack’s sugar claim and storage directions rather than assuming this larger drink meets a no-added-sugar requirement.
A Joybuy drink option
This option is a no-added-sugar juice drink for shoppers willing to choose an ambient drink instead of a fruit smoothie.

Ribena Strawberry No Added Sugar Cartons 24x250ml
Consider this carton if carrying a juice drink rather than a smoothie suits your plans. Each carton is 250ml, so decide how much you intend to drink in light of the NHS’s combined 150ml daily guidance for fruit juice and smoothies. Check the current pack for storage directions and sweeteners if either affects your choice.
Questions about gym-bag drinks
Does no added sugar mean a fruit smoothie is sugar-free?
No. A fruit smoothie can contain naturally occurring sugars without added sugar. Read the sugars figure on its nutrition panel alongside the pack volume to assess the amount you plan to drink.
How much smoothie should I count as a daily portion?
The NHS advises limiting fruit juice and smoothies to a combined total of 150ml a day. A 150ml pouch matches that volume; a 250ml bottle or larger carton needs portioning if you are following that guidance.
Can I keep a smoothie in my gym bag?
Follow the exact pack’s storage instructions. Waitrose & Partners states that an innocent 150ml children’s pouch lasts up to 12 hours out of the fridge, whereas Tesco Groceries instructs shoppers to keep the innocent 250ml strawberries-and-bananas bottle at 0–8°C. The pouch allowance cannot be assumed for other packs.
Is an ambient no-added-sugar juice drink the same as a smoothie?
No. A juice drink is a different product type. Tesco Groceries describes its no-added-sugar pineapple-and-coconut option as a juice drink with sweetener that can be stored unopened in a cool, dry place; check its ingredients if you are considering it instead of a smoothie.
