Choose a fruit smoothie if you want a fruit-based drink with a meal; choose a clearly labelled sparkling drink if fizz matters more. The NHS advises limiting fruit juice and smoothies combined to 150ml a day, so a large smoothie bottle needs portioning rather than treating it as one revision-session drink.
A ready-to-drink smoothie may be convenient between revision sessions, but bottle size and serving size are different things. The NHS advises a combined daily limit of 150ml for fruit juice and smoothies; the Waitrose and Innocent 750ml examples each contain five 150ml servings.
If carbonation is the deciding feature, look for a drink explicitly labelled sparkling. M&S lists smoothies and sparkling drinks as distinct types of chilled drink, so a smoothie listing alone does not establish that it is fizzy.
Fruit smoothie recipes differ: the Waitrose Strawberry & Banana and Innocent Pineapples, Bananas & Coconuts products are distinct blends. Check the exact pack for ingredients, dietary suitability and instructions for keeping an opened bottle.
Choose it when: You want a fruit-based drink with a meal and can pour a measured portion.
Bear in mind: The NHS advises limiting fruit juice and smoothies together to 150ml a day, even when a bottle contains several servings.
Choose it when: Carbonation is more important than buying a fruit-purée smoothie.
Bear in mind: Sparkling water and sweetened sparkling drinks are different choices; check the exact drink’s ingredients and sugar information.
| Priority | What to check | Your needs |
|---|---|---|
| Fizz or fruit blend | Check whether the label says smoothie, sparkling water or sparkling drink. Do not assume a fruit-flavoured fizzy drink contains fruit purée. | If I chiefly want fizz, I will choose a clearly labelled sparkling drink. If I want a smoothie, I will check that exact product’s label rather than expect carbonation. |
| Portion size | Compare the bottle volume with its stated serving size. The NHS advises no more than 150ml of fruit juice and smoothies combined per day, with a meal. | A large bottle might last across several breaks; I need a way to measure a portion and store what remains. |
| Sugar information | Read sugars per 100ml and per serving where stated, keeping the units consistent when comparing drinks. The NHS notes that fruit juice and smoothies are high in sugar. | I want to know what my intended portion contains, rather than judge a drink by its fruit description or bottle size. |
| Ingredients and storage | Check the exact ingredient and allergen information, refrigeration temperature and use-after-opening instruction. Waitrose states below 5°C and four days after opening for its 750ml Strawberry & Banana Smoothie. | If I am buying one bottle for several study sessions, I need its ingredients to suit me and somewhere to keep it as the pack directs. |
M&S lists smoothies separately from sparkling drinks. Buying by flavour alone could leave you with a still smoothie when you wanted fizz, or a fizzy drink when you wanted a fruit-purée smoothie.
Decide which drink type matters first, then check the exact label for carbonation, ingredients and sugar.
The Waitrose and Innocent 750ml smoothie examples each contain five 150ml servings. Drinking the bottle at once would exceed the NHS advised daily combined limit of 150ml for fruit juice and smoothies.
Check the serving size, pour the portion you intend to have with a meal, and refrigerate the remainder as directed.
The Waitrose Strawberry & Banana Smoothie and Innocent Pineapples, Bananas & Coconuts Smoothie both specify use within four days of opening, with different stated refrigeration temperatures.
Follow the instructions on the pack you buy, and check its current ingredients and allergens.
A bottle intended to last longer than its stated use-after-opening period could leave some of the drink unused.
These examples help distinguish smoothie recipes and pack formats; a brand name alone does not tell you whether a particular drink is sparkling.

Do not assume it is. M&S lists smoothies separately from sparkling drinks; check the exact label for carbonation and ingredients if you want both fizz and a fruit-purée smoothie.
Choose water for an ongoing drink rather than using a large smoothie as routine hydration. The NHS includes water as a hydration choice and advises limiting fruit juice and smoothies combined to 150ml a day; sparkling water is an option if you prefer fizz.
Follow the instructions on the exact pack and keep it refrigerated as directed. Waitrose specifies below 5°C and use within four days of opening for its Strawberry & Banana Smoothie; the listed Innocent Pineapples, Bananas & Coconuts Smoothie specifies 0–8°C and four days.
