Choose a smoothie by checking the total sugars, bottle size and any dietary claim that matters to you; ‘no added sugar’ does not mean sugar-free. The NHS advises limiting fruit juice, vegetable juice and smoothies to a combined 150ml a day, so plan how much of a larger bottle you intend to drink. If you are bringing one from outside the airport, check the departure airport’s liquid rules before you reach security.
The useful distinction is not whether a drink is called a smoothie, but which label details matter for your journey and dietary requirements.
A no-added-sugar label does not describe the total sugar content. Compare the nutrition panel and decide how much of the bottle you intend to drink; the NHS advises a combined daily limit of 150ml for juice and smoothies.
Look for vegan suitability on the exact bottle rather than assuming every fruit smoothie qualifies. The Innocent Fruit + Veg and Naked Protein Machine products described by Waitrose & Partners and Sainsbury's respectively are labelled as suitable for vegans, but the label on the product you buy is the relevant check.
If protein is the deciding feature, check both its stated amount and the serving size. Sainsbury's lists 10g protein per 300ml serving for Naked Pineapple & Mango Protein Machine; its 750ml bottle contains 2–3 servings.
Start with the nutrition and ingredients on the exact bottle, then consider whether its size works with your portion plan and airport journey.
| Priority | What to check | Your needs |
|---|---|---|
| Total sugars | Read the total sugars per 100ml, not just a ‘no added sugar’ claim. Tesco Groceries lists 10g per 100ml for Innocent Strawberries, Bananas & Apples; Waitrose & Partners lists 9.6g per 100ml for Innocent Fruit + Veg. | I want to know how much sugar the drink contains, including naturally occurring sugars, before choosing a bottle. |
| Portion size | Check bottle volume and labelled servings. The NHS advises limiting fruit juice, vegetable juice and smoothies to a combined 150ml a day; a larger bottle need not be drunk in one go. | A bottle may be convenient for the journey, but I want to decide how much I will drink rather than treating the whole pack as one portion. |
| Vegan suitability | Check the exact product’s vegan statement and ingredients. Do not apply a claim from one smoothie to other flavours or recipes in the range. | If I need a vegan drink, I want that suitability stated for the bottle I pick up. |
| Added protein | Compare protein amounts on the same serving basis and check the bottle size. Sainsbury's lists 10g protein per 300ml serving for Naked Pineapple & Mango Protein Machine, in a 750ml bottle containing 2–3 servings. | Protein matters to my choice, but I also want to account for how much of the drink a stated serving represents. |
| Security and storage | Check the departure airport’s current liquid rules before taking a bottle through security. GOV.UK says containers over 100ml cannot pass through security at most UK airports, even when partly full; also follow the bottle’s storage instructions. | I would rather decide when to buy the smoothie than discover at security that its container cannot go through. |
Fruit smoothies can contain naturally occurring sugars. Tesco Groceries lists 10g sugars per 100ml for Innocent Strawberries, Bananas & Apples, while Waitrose & Partners lists 9.6g per 100ml for Innocent Fruit + Veg.
Use the total-sugars line and the amount you plan to drink when comparing bottles. Keep the units consistent: a value per 100g is not directly interchangeable with one per 100ml.
The NHS advises a combined daily limit of 150ml for fruit juice, vegetable juice and smoothies. A 250ml bottle exceeds that amount, and Sainsbury's describes the reviewed 750ml Naked bottle as containing 2–3 servings.
Check both the bottle volume and the serving information, then decide what quantity fits your plan.
GOV.UK says that, at most UK airports, liquid containers larger than 100ml cannot pass through security, even if partly full. A standard smoothie bottle may therefore have to be left behind.
Check the rules for your departure airport and any later security checkpoint. If you plan to buy after security, check what is available at your terminal.
Smoothie recipes differ: Marks & Spencer describes options made with ingredients such as yoghurt, dates and oats. A range description cannot establish the ingredients or allergen information for a particular bottle.
Read the exact product’s ingredients, allergen information and nutrition panel. For a prescribed diet, follow your individual clinical advice rather than relying on a general smoothie description.
These examples show why the exact recipe and serving information matter; a claim about one bottle does not apply across a whole range.
Tesco Groceries and Waitrose & Partners list distinct Innocent fruit and fruit-and-veg smoothies, making the product name important when comparing their labels.
Sainsbury's lists Naked Pineapple & Mango Protein Machine for shoppers specifically comparing smoothies with added plant protein.
Marks & Spencer describes ready-made smoothies in 350ml and 750ml formats, including blends made with yoghurt, dates and oats.
This coconut-milk and papaya smoothie is a fruit-containing bottle to assess against your portion, ingredient and airport-security needs.

The stated 180ml bottle gives you a pack size to plan around, whether you intend to drink it at the airport or take it on a journey.
Check the current ingredients and nutrition label if sugar content or vegan suitability matters to you. For security, GOV.UK says a container over 100ml cannot pass through at most UK airports; check your departure airport’s rules before carrying this bottle through.
At most UK airports, no: GOV.UK says liquid containers over 100ml cannot pass through security, even if partly full. Check the departure airport’s current rules and any later security checkpoint before relying on an exception.
No. Tesco Groceries lists 10g sugars per 100ml for Innocent Strawberries, Bananas & Apples, and Waitrose & Partners lists 9.6g per 100ml for Innocent Fruit + Veg; both describe sugars occurring naturally in their ingredients. Read the total-sugars value on the exact bottle.
The NHS says 150ml of fruit juice, vegetable juice or smoothie counts as one portion and advises limiting these drinks to a combined 150ml a day. Drinking a larger bottle does not make it count as additional 5 A Day portions.
Check the exact bottle’s current ingredients, allergen information and any vegan statement, rather than relying on the brand or flavour name. If the drink is prepared and packed by an outlet for direct sale, use its product-specific written ingredient information as well.
