People who dislike sweet drinks after exercise
If you want soya drink in a shake, cereal or a snack without a sweet flavour, look for an explicit taste description as well as the sugar figure. Alpro describes Soya No Sugars as mild and balanced.
Who is this for?
Plant-based shoppers comparing protein
If the drink needs to contribute protein after a longer session, compare protein per 100ml and the amount you will actually pour. British Heart Foundation guidance also discusses having carbohydrate alongside protein after exercise lasting longer than an hour.
Everyday unsweetened soya drink buyers
If you mainly want a drink for cereal or occasional post-workout snacks, Tesco Longlife and Waitrose Essential Unsweetened are own-label examples listing protein, calcium and iodine. Their unsweetened labels do not tell you whether you will find the flavour mild.
What should you check?
Decide whether a stated mild flavour or the drink’s protein contribution matters more, then check how it fits with the rest of your snack.
| Priority | What to check | Your needs |
|---|---|---|
| Mild flavour | Look for an explicit flavour description; check sugars and sweeteners separately. Alpro describes Soya No Sugars as mild and balanced. | I would rather have a drink that does not taste noticeably sweet in a shake or snack. |
| Protein | Compare labels per 100ml, then calculate your serving. Alpro lists 3.3g for Soya No Sugars and 5g for High Protein Plain per 100ml. | The amount I pour needs to make a useful contribution to my post-workout food, rather than just looking substantial on the carton. |
| Food alongside it | Consider the drink with the rest of your snack. The British Heart Foundation discusses carbohydrate alongside protein after exercise lasting longer than an hour; the British Dietetic Association advises prompt carbohydrate-rich food or fluids when quick recovery is required. | After a long session, or when I need to recover quickly, I may want cereal, fruit, toast or a meal with my drink. |
| Fortification | Check the exact carton for added nutrients. Tesco Longlife and Waitrose Essential Unsweetened list calcium and iodine. | I use soya drink regularly as well as after exercise, so I want to compare what each carton contains. |
| Allergens | Read the current ingredients and allergy statement. Soya is a declarable allergen in UK food labelling, as covered by GOV.UK guidance. | If I am buying for someone with an allergy, the current carton matters more than an older listing. |
What is easy to overlook?

Treating a zero-sugar drink as the entire post-workout snack
A soya drink can contribute protein, but the British Heart Foundation discusses carbohydrate alongside protein after exercise lasting longer than an hour.
For a longer session, consider the drink with carbohydrate-containing food and check how much protein your serving provides.
-
Assuming unsweetened means mild
A sugar figure does not describe how a drink tastes. Alpro explicitly calls its Soya No Sugars flavour mild and balanced; the compared own-label labels do not make that same taste claim.
If flavour is decisive, look for a specific description or try a carton before choosing a larger pack.
-
Comparing protein without comparing serving sizes
The labelled examples range from 2.2g to 5g protein per 100ml, according to Sainsbury’s and Alpro product information. Those figures do not tell you the contribution of a glass until you know its size.
Use the same per-100ml basis for comparison, then calculate the amount in your usual serving.
-
Skipping the current allergy label
Soya is an allergen that must be declared when it is an ingredient under UK food-labelling guidance from GOV.UK.
If you are buying for someone with an allergy, check the ingredients and allergy statement on the current carton.
Relevant brand options
These labelled examples illustrate different flavour and protein choices; a brand name alone does not establish how every drink in its range tastes.
Alpro
Its No Sugars and High Protein Plain drinks address different parts of the mild-flavour and protein decision.
- Alpro describes Soya No Sugars as mild and balanced; it lists 0g sugars and 3.3g protein per 100ml.
- High Protein Plain lists 5g protein and 2.5g sugars per 100ml, without the same stated mild-flavour description.
Tesco
Tesco Longlife Soya Drink Unsweetened is an own-label option for everyday use.
- Tesco Groceries lists 3.4g protein and 0.5g sugars per 100ml, plus calcium and iodine.
- The unsweetened description does not establish a mild flavour.
Waitrose Essential
Essential Unsweetened Soya Drink offers another own-label nutrition profile to compare.
- Waitrose & Partners lists 3.4g protein and 0g sugars per 100ml, plus calcium and iodine.
- A zero-sugars figure is not a description of mildness.
Sainsbury’s
Its Unsweetened Soya Drink is a separate everyday option, rather than a like-for-like protein match with every drink above.
- Sainsbury’s lists 2.2g protein and less than 0.5g sugars per 100ml, with added calcium, iodine, vitamin D and B12.
- Its listed protein per 100ml is lower than the Alpro, Tesco and Waitrose examples here.

Alpro Soya Drink OG, 6-pack
A six-unit soya-drink listing to consider for cereal or shakes. Check the carton’s flavour description and nutrition panel before choosing it specifically for mild taste or a particular protein contribution.

Vita Low-Sugar Soy Milk, 6 x 250ml
Individual 250ml cartons may suit a drink taken with a snack. Check sugars and protein per 100ml on the current nutrition panel: the Low-Sugar wording should not stand in for those figures or for a mild-flavour description.
Common questions
Is a mild soya drink enough on its own after a workout?
After exercise lasting longer than an hour, British Heart Foundation guidance discusses protein alongside carbohydrate. If quick recovery is required, the British Dietetic Association advises starting carbohydrate-rich food or fluids promptly. Consider the drink alongside food rather than assuming it covers both.
How much protein is in a 250ml glass?
Using their listed per-100ml figures, a 250ml serving contains about 8.25g protein from Alpro Soya No Sugars, 8.5g from either Tesco Longlife or Waitrose Essential Unsweetened, or 12.5g from Alpro Soya High Protein Plain. Check your actual serving size before comparing.
Does unsweetened soya drink necessarily taste mild?
No. Unsweetened describes sweetening, not your experience of the flavour. Alpro describes its Soya No Sugars drink as mild and balanced; for another drink, check its flavour description or try it before buying a larger pack.
What if I am buying for someone with a soya allergy?
Do not choose a soya drink for someone allergic to soya. GOV.UK guidance identifies soya beans among the allergens that must be declared when they are ingredients; read the ingredients and allergy statement on the current carton.
