Runners who prefer a mellow flavour
If you use soya drink in porridge, cereal or smoothies, flavour may decide which carton you enjoy using regularly. Keep that preference separate from your plans for carbohydrate around longer or harder runs.
Who is this choice for?
A mild soya drink can play different roles in a training routine, depending on what else is in the meal and which carton you choose.
Plant-based runners planning recovery food
A soya drink can contribute to a mixed snack or meal. Compare protein on the exact carton, and consider the carbohydrate-containing food and fluids alongside it after intense or prolonged exercise, as advised by the UK Sports Institute.
Shoppers choosing an everyday carton
Chilled and long-life formats suit different storage plans. Compare the nutrition panel, carton size and instructions after opening rather than assuming that all unsweetened drinks have the same contents.
What should you check?
Start with the role the drink will have in your meal, then compare the exact carton's nutrition and storage information.
| Priority | What to check | Your needs |
|---|---|---|
| Training fuel | Read carbohydrate per serving. Sainsbury's lists 3.0g per 250ml and Waitrose & Partners lists 2.0g per 250ml for their specified unsweetened drinks; consider the carbohydrate in the whole meal or snack. | I want a mild drink with breakfast before a demanding run, but I will plan carbohydrate-containing food rather than treat the drink as the meal's only fuel. |
| Recovery meal | Compare protein using the same serving size: Sainsbury's lists 5.6g per 250ml and Waitrose & Partners lists 8.5g per 250ml. The UK Sports Institute advises carbohydrate, protein and fluids after intense or prolonged exercise. | After a hard session, I want to know what the drink contributes to a snack and what else I need to include with it. |
| Added nutrients | Check the exact carton for calcium, iodine and added vitamins, alongside its protein and carbohydrate values. The UK government's assessment says nutrient content varies considerably between plant-based drinks. | If soya drink is a regular part of my meals, I want to compare its label rather than assume every unsweetened carton contains the same nutrients. |
| Flavour and sugars | Look for a flavour description that suits you, then read sugars per serving. Sainsbury's describes Alpro Soya No Sugars as mild and mellow; that description does not establish the taste of other unsweetened drinks. | A mellow drink that works in porridge or a smoothie matters to me, without choosing solely by a front-of-pack claim. |
| Storage and format | Check whether the carton is chilled or long-life, its pack size, and its instructions once opened. Long-life describes storage before opening, not how long an opened carton keeps. | I want a format I can store and use in time, whether I buy one carton for breakfast or a multipack. |
| Soya allergen | Read the current ingredients and allergen label. The Food Standards Agency identifies soya as a possible health risk for people with a soya allergy. | If I need to avoid soya, a dairy-free or vegan description does not make a soya drink suitable for me. |
Common buying mistakes
-
Treating unsweetened soya drink as complete run fuel
The British Dietetic Association identifies carbohydrate as the main fuel for exercising muscles. The specified Sainsbury's and Waitrose unsweetened drinks contain 3.0g and 2.0g carbohydrate per 250ml respectively.
Use the drink as part of a meal or snack with carbohydrate-containing food when planning for a demanding session; tailor the overall plan to the run.
-
Assuming all soya drinks have the same nutrients
The UK government's assessment says plant-based drinks vary considerably in nutrient content. An unsweetened label alone does not tell you how much protein or which added nutrients a carton contains.
Compare the nutrition and ingredients panels for the exact product and format you intend to buy.
-
Overlooking soya on an allergen label
A dairy-free or vegan soya drink still contains soya. The Food Standards Agency identifies products containing soya as a possible risk for people with a soya allergy.
If you must avoid soya, do not choose a soya drink; check the current label of any alternative.
-
Planning storage around an unopened carton
A long-life carton's unopened storage format does not tell you how to keep it after opening.
Check the pack's opened-carton instructions and choose a quantity that fits how quickly your household will use it.
An opened carton that cannot be used within its stated storage period may go to waste.
Brand and retailer references
These named ranges illustrate label and format differences; each description applies to the specified drink or listing, not every product from that brand or retailer.
Alpro
Sainsbury's describes Alpro Soya No Sugars Long Life Drink as having a mild, mellow soya taste.
- A directly described mellow option for shoppers who want a no-sugar soya drink.
- Its flavour positioning does not make the drink a substitute for carbohydrate-containing food around demanding runs.
Sainsbury's
Its Unsweetened Soya Drink listing gives, per 250ml, 5.6g protein, 3.0g carbohydrate, 300mg calcium and 56.3µg iodine.
- The stated serving values make it possible to compare the drink's contribution to a meal.
- Its stated carbohydrate amount is not a replacement for a carbohydrate-containing training meal or snack.
Waitrose Essential
Waitrose & Partners lists its Essential Unsweetened Soya Drink with 8.5g protein, 2.0g carbohydrate, 300mg calcium and 56.0µg iodine per 250ml.
- The listed protein and nutrient amounts offer specific figures to compare with other cartons on the same serving basis.
- Its stated carbohydrate amount means the rest of a training meal or snack still matters.
Tesco
Tesco Groceries lists both Tesco Soya Drink Unsweetened and Tesco Longlife Soya Drink Unsweetened.
- The listed options give shoppers chilled and long-life formats to consider.
- Check the chosen carton's own nutrition and storage label rather than applying another retailer's values to it.
Joybuy soya drink options
The option shown here is an Alpro no-sugar, long-life multipack for shoppers who want a mild soya drink to use with food; it is not a complete fuelling plan for a run.

Alpro Soya No Sugars Long Life Drink, 8 x 1L
A no-sugar soya drink for use with cereal, porridge or smoothies; Joybuy describes its soya taste as mellow. The pack contains eight 1L long-life cartons. Plan carbohydrate-containing food separately when using it around demanding runs, and check the current carton for the nutrient values and opened-carton storage instructions relevant to you.
Questions about choosing soya milk
Is unsweetened soya milk enough fuel before a long run?
Not on its own as the carbohydrate-containing part of a meal. The British Dietetic Association identifies carbohydrate as the main fuel for exercising muscles, while the specified unsweetened Sainsbury's and Waitrose drinks list just 3.0g and 2.0g carbohydrate per 250ml respectively. Consider the food you have with the drink when planning for the run.
What should I compare on a soya-drink carton?
Compare carbohydrate, sugars and protein on the same serving basis, then check whether the exact carton lists added nutrients that matter to your overall diet, such as calcium, iodine, vitamin D or B12. The UK government's assessment says nutrient content varies considerably between plant-based drinks.
Does dairy-free mean a soya drink is suitable for someone with a soya allergy?
No. A soya drink contains soya regardless of a dairy-free or vegan description. The Food Standards Agency identifies soya-containing products as a possible health risk for people with a soya allergy; check the current allergen label and choose a suitable alternative if you must avoid soya.
How should I store a carton after opening it?
Follow the opened-carton instructions on the exact pack. A long-life description concerns storage before opening, so check the refrigeration and use-by-opening directions when deciding whether a single carton or multipack fits your household.
