Choose a chilled smoothie if you want a fruit-based snack and can keep it refrigerated until drinking; choose a sparkling fruit drink if fizz matters more than smoothie texture. Check the exact product’s storage instructions and serving size before putting it in your bag. The NHS advises limiting fruit juice and smoothies to a combined 150ml a day because they contain free sugars.
A chilled smoothie is an option if you want that fruit-and-purée format and can follow its refrigeration instructions until you drink it. The Innocent, Naked and M&S examples listed by Waitrose & Partners and Ocado require refrigeration.
If carbonation is the deciding feature, look for a drink explicitly described as sparkling. Marks & Spencer’s sparkling apple spring water and the Cawston Press sparkling water listed by Ocado are different product formats from a conventional smoothie.
If you mainly want something to drink during exercise, you can carry water and decide separately whether you also want a fruit snack. If that snack is a smoothie, the NHS’s combined 150ml daily guidance for fruit juice and smoothies remains relevant.
Decide whether the drink is meant to be a smoothie snack or a fizzy drink, then check how you will carry it and how much you intend to drink.
Choose it when: You want a smoothie and can keep the bottle refrigerated until drinking.
Bear in mind: A small bottle can still need refrigeration, and a full bottle may exceed the NHS’s combined 150ml daily guidance for juice and smoothies.
Choose it when: You want carbonation rather than a conventional smoothie.
Bear in mind: Sparkling drinks vary in their ingredients and storage instructions; fruit imagery does not tell you whether a product is a smoothie.
| Priority | What to check | Your needs |
|---|---|---|
| Drink format | Read the product name and ingredients. Look for an explicitly sparkling drink if you want fizz, or a product described as a smoothie if you want that format. | Am I after a smoothie snack, or do I mainly want a fizzy fruit drink? The sparkling water examples from Marks & Spencer and Ocado are not described as smoothies. |
| Storage | Check the exact product’s instructions and whether you can maintain the required conditions until drinking. Ocado’s Naked and M&S smoothie listings both specify refrigeration. | If the bottle will sit in my bag for a while, I need a way to follow its storage instructions rather than assuming a compact drink can stay out of the fridge. |
| Portion size | Compare bottle volume with the amount you plan to drink. The NHS advises a combined daily limit of 150ml for fruit juice and smoothies; Ocado describes its 300ml Naked Blue Machine bottle as two servings. | Will I drink the whole smoothie? A full 300ml bottle is more than the NHS’s combined 150ml daily guidance for juice and smoothies. |
| Ingredients | Check the exact variant’s ingredient list, allergen information and nutrition values per 100ml when comparing drinks. | I want to know what is in this particular can or bottle, especially if an ingredient or allergen matters to me. |
| Container | Check the stated volume and container type, and consider how you will carry it. | A larger bottle or a glass container may change what I am comfortable carrying alongside my gym kit. |
A drink can contain fruit juice and still be a sparkling water or soft drink rather than a fruit-and-purée smoothie. The Marks & Spencer and Cawston Press sparkling examples use sparkling water.

Read the exact product name to distinguish a smoothie from a sparkling drink, then check its ingredients, allergens, nutrition information, serving size and storage instructions. Do not rely on fruit imagery or the name of a product range to identify the contents of a particular variant.
If hydration is your main reason for carrying a drink, water is an option; you can decide separately whether you also want a smoothie as a snack. For any juice or smoothie you choose, the NHS’s combined 150ml daily guidance still applies.
