People carrying a drink to training
An unopened carton may fit the journey, but its size matters if you will have no way to refrigerate what remains after opening.
Who is this for?
People planning a snack around a soya drink
The drink is one part of the snack. Compare its carbohydrate and protein information with the other food you plan to bring.
Shoppers comparing unsweetened and fortified drinks
Check the exact carton for its ingredients, protein and added nutrients rather than treating all soya drinks as the same formulation.
What should you check?
Start with how much you will carry and whether you can refrigerate an opened carton; then compare labels for the qualities you want from the drink.
| Priority | What to check | Your needs |
|---|---|---|
| Carton size and storage | Compare an individual carton with a larger one. Read the unopened and opened storage instructions on the exact pack, including its refrigeration requirement. | I want to carry one drink without having to manage a larger opened carton afterwards. |
| Snack composition | Read carbohydrate and protein amounts on the same serving basis, then consider the other food in the snack. University College London Hospitals NHS Foundation Trust describes both carbohydrate and protein as components of an exercise snack. | The drink will be part of my snack, so I want to know what it contributes alongside the food I bring. |
| Ingredients and fortification | Check the exact ingredient and nutrition panels for sugars, protein and any added calcium or vitamins. Tesco Groceries lists added calcium, iodine and vitamins for Alpro Soya Original; that description does not apply to every variant. | If I choose an unsweetened drink, I still want to check its other nutritional details rather than rely on that label alone. |
| Allergens | Read the current ingredient and allergen label for everyone who may drink it. The Food Standards Agency identifies soya as an allergen. | If I am sharing snacks, I need to know whether soya is suitable for each person. |
Common buying mistakes
-
Treating a large long-life carton as an all-day opened drink
Long-life storage instructions change after opening. Waitrose & Partners says its listed Alpro Organic No Sugar drink must then be kept at +1°C to +7°C and used within 5 days; Sainsbury's gives its own unsweetened drink a 3-day period after opening.
Choose a carton size you can use while following its opened-pack instructions, and check those instructions before putting it in your bag.
-
Choosing by a protein claim alone
A front-of-pack description does not tell you how much protein you would get from the amount you intend to drink.
Compare the current nutrition panels on the same per-100ml or serving basis, including the serving size you actually plan to have.
-
Assuming unsweetened tells you everything else
Ingredients and fortification differ between products. Tesco Groceries lists added nutrients for Alpro Soya Original, while Sainsbury's lists spring water and organic soybeans as the ingredients of Plenish Organic Soya Drink.
Decide whether ingredients, added nutrients or a particular nutrition value matters to you, then read the label of that precise carton.
-
Overlooking soya when sharing snacks
The Food Standards Agency identifies soya as an allergen that can pose a risk to someone with a soya allergy.
Check with anyone sharing the snack and keep the labelled carton available so its ingredients can be read.
Brand and product-line references
These examples illustrate differences between particular UK-listed cartons, not a claim that every product from a brand has the same formulation or storage instructions.
Alpro
Tesco Groceries lists long-life Alpro Soya Original and High Protein variants, while Waitrose & Partners lists an Organic No Sugar variant.
- Tesco Groceries lists added calcium, iodine and vitamins B2, B12 and D2 for Soya Original.
- The Organic No Sugar carton listed by Waitrose & Partners requires refrigeration at +1°C to +7°C after opening and use within 5 days. Check the instructions for the variant you buy.
Sainsbury's
Sainsbury's lists a 1L unsweetened long-life own-label soya drink.
- Its product listing gives protein values per 100ml and per 250ml serving.
- The listed drink must be refrigerated and used within 3 days after opening; those instructions are specific to this product.
Plenish
Sainsbury's lists a 1L long-life Organic Soya Drink from Plenish.
- The listing names spring water and organic soybeans as its ingredients.
- Sainsbury's says to refrigerate this product after opening and consume it within 4 days; check its nutrition panel if added nutrients are a priority.

Vita Low-Sugar Soy Milk, 6 × 250ml
Six smaller cartons give you the option of packing one drink rather than carrying the whole pack. Check the carton's sugar information and opened-pack storage instructions against your plans.
No image available
Vitasoy Malted Soy Milk, 6 × 250ml
The six-carton format lets you take a 250ml drink for a snack. Read the ingredient and allergen label, particularly if barley or soya is a concern for anyone who may drink it.

YON HO Black Soybean Drink, 300ml
This 300ml drink is another single-container size to consider for a gym bag. Check its nutrition panel if you are comparing it with a 250ml carton, and follow its storage directions after opening.
No image available
Alpro Soya No Sugars Long Life Drink, 8 × 1L
This pack contains eight larger cartons; you can take one carton, but consider how you would store any drink left after opening it. Check this variant's own nutrition and storage labels rather than applying instructions from another Alpro product.
No image available
YONHO Black Soybean Drink, 920ml
The 920ml container suits a different carrying plan from an individual 250ml or 300ml drink. Read its label before relying on unopened storage outside a fridge, and plan for any leftovers after opening.
Frequently asked questions
Can I put an unopened long-life soya drink in my gym bag?
Yes, if the specific carton permits storage outside a fridge before opening. Waitrose & Partners gives ambient-before-opening instructions for its listed Alpro Organic No Sugar drink; read the label of the carton you intend to carry.
Can an opened carton stay in my gym bag?
Follow the carton's refrigeration instructions rather than treating it as an unopened long-life drink. Waitrose & Partners specifies +1°C to +7°C and use within 5 days for its listed Alpro Organic No Sugar drink; Sainsbury's says to refrigerate its listed unsweetened own-label drink and use it within 3 days.
Is a soya drink the whole snack I need around training?
Do not assume that a soya drink alone provides everything you want from a snack. University College London Hospitals NHS Foundation Trust describes carbohydrate and protein among the components of an exercise snack, so check the drink's label alongside any food you plan to take.
Can someone with a soya allergy have a soya drink?
No. The Food Standards Agency identifies soya as an allergen that can pose a health risk to someone with a soya allergy. Check the current product label before offering a drink to anyone else.
