Vegan gym-goers comparing protein
Standard and high-protein soya drinks can provide different amounts of protein. Compare the nutrition panel for the portion you expect to drink rather than relying on the vegan claim.
Who is choosing a post-gym soya drink?
The useful comparison depends on whether protein, sugars or allergen information matters most for your snack.
Shoppers watching sugars
An unsweetened or no-sugars drink may suit your preference, but check its protein figure too. A sweetened high-protein carton answers a different need.
Vegan shoppers with allergy concerns
Vegan suitability and allergen suitability are separate checks. Read the ingredients and any precautionary allergen statement on the exact product you intend to use.
What should you check on the carton?
Start with vegan suitability and the protein in your likely serving; then weigh sugars, fortification and format against how you will use the drink.
| Priority | What to check | Your needs |
|---|---|---|
| Protein | Compare grams per 100ml, then check the amount in the serving you plan to drink. Sainsbury's lists 5.0g per 100ml and 12.5g per 250ml serving for its Sweetened High Protein Soya Drink. | I want to know what the drink contributes to my snack, without assuming every vegan soya carton has the same protein content. |
| Sugars | Read sugars and protein together on the same per-100ml basis. Sainsbury's lists 2.9g sugars per 100ml for its sweetened high-protein drink; ASDA Groceries lists 0g for Alpro Organic Soya No Sugars. | Keeping sugars down matters more to me than getting the highest protein figure from the drink alone. |
| Vegan and allergen labels | Confirm vegan suitability, then read the ingredients, declared allergens and precautionary statements. The Food Standards Agency cautions that vegan labelling is not a substitute for allergen labelling. | I need a vegan drink, but an allergy means I must check the exact carton separately for relevant warnings. |
| Fortification | If you use soya drink regularly as a dairy alternative, check the current pack for calcium, iodine, vitamin D and vitamin B12. ASDA and M&S list these additions for the soya drinks described below. | I use the drink beyond an occasional post-gym snack and want to know which nutrients this particular carton lists. |
| Serving format | Check bottle or carton size, the number of units and storage directions. Confirm the pack count where a listing's quantity is unclear. | A single bottle is easier for me to take along; larger cartons make more sense when I will pour a serving at home. |
What mistakes are easy to make?
-
Assuming every vegan soya drink is equally high in protein
ASDA Groceries lists 2.0g protein per 100ml for ASDA Plant Based Soya Unsweetened, compared with Sainsbury's listed 5.0g per 100ml for its Sweetened High Protein Soya Drink. A vegan label does not indicate a protein amount.
Compare the per-100ml figures and the portion you will actually drink. If the drink contributes less protein than you want from the snack, consider it alongside another suitable food.
-
Reading ‘high protein’ as ‘no sugar’
Sainsbury's sweetened high-protein drink lists 2.9g sugars per 100ml. ASDA Groceries lists 0g sugars and 3.3g protein per 100ml for Alpro Organic Soya No Sugars, so the two labels address different priorities.
Compare both protein and sugars on the nutrition panels before choosing between these drinks.
-
Using a vegan label as an allergy check
The Food Standards Agency says vegan labelling alone should not stand in for allergen labelling. ASDA Plant Based Soya Unsweetened declares soya and says it may contain nuts; M&S says its Plant Kitchen Soya Drink is unsuitable for people with nut or peanut allergy.
If an allergy is relevant, check the ingredients and precautionary statements on the current pack of the exact drink.
Which brand ranges are relevant?
These examples show why it is more useful to compare individual soya drinks than to choose by brand name alone.
Alpro
Alpro has distinct high-protein and no-sugars soya drinks, rather than one nutrition profile across its range.
- ASDA Groceries lists 3.3g protein and 0g sugars per 100ml for Alpro Organic Soya No Sugars.
- For Alpro High Protein Soya, check the exact carton's protein figure before comparing it with another drink.
Sainsbury's
Its Sweetened High Protein Soya Drink is a vegan-labelled option with stated protein values.
- Sainsbury's lists 5.0g protein per 100ml and 12.5g per 250ml serving.
- The same drink is sweetened and lists 2.9g sugars per 100ml.
ASDA Plant Based
Its Unsweetened Soya Drink offers a Vegan Society-marked route with stated fortification.
- ASDA Groceries lists less than 0.5g sugars and 2.0g protein per 100ml, plus calcium, iodine and vitamins D2, B2 and B12.
- The product contains soya and may contain nuts.
M&S Plant Kitchen
Its Soya Drink is a vegan-labelled, fortified option; its declared protein and sugar figures use a per-100g basis.
- M&S lists 2.8g protein and 2.0g sugars per 100g, with added calcium, iodine, vitamin D and vitamin B12.
- M&S says this drink is unsuitable for people with nut or peanut allergy.
Tesco
Tesco Groceries lists both sweetened and unsweetened own-label soya drinks alongside other brands.
- The range gives shoppers different labelled formats and varieties to compare.
- Check each product's own vegan information and nutrition panel; a category listing does not establish those details for every carton.

Alpro Soya No Sugars Long Life Drink 8 x 1L
The no-sugars variant is worth checking if sugars are a deciding factor in your post-gym drink. Compare its protein per serving with other cartons, and confirm vegan suitability and allergen information on the exact pack. The listed format is 8 x 1L.

Yeo's Soy Bean Drink 300ml x 3
The listed three-bottle format offers separate 300ml drinks to consider for taking after a gym session. Check the exact bottles for vegan suitability, protein, sugars and allergen statements rather than assuming their nutrition matches a larger soya carton.

This 300ml bottle is a single-serving format to consider for a post-gym snack. Read its current vegan, nutrition and allergen labels to judge whether the drink fits the snack you have in mind.
Common questions
Is a standard vegan soya drink enough for a post-gym snack?
It can contribute protein, but the amount depends on the drink and the serving. ASDA Groceries lists 4.0g per 200ml for ASDA Plant Based Soya Unsweetened, while Sainsbury's lists 12.5g per 250ml for its Sweetened High Protein Soya Drink. Consider what else you will have with the drink rather than treating the vegan label as a protein measure.
Should I choose a high-protein or a no-sugars soya drink?
Choose according to which figure matters more to you, checking both on the same per-100ml basis. Sainsbury's Sweetened High Protein Soya Drink lists 5.0g protein and 2.9g sugars per 100ml; ASDA Groceries lists 3.3g protein and 0g sugars per 100ml for Alpro Organic Soya No Sugars.
Does a vegan logo mean a soya drink is suitable for someone with allergies?
No. The Food Standards Agency cautions that vegan labelling alone is not a substitute for allergen labelling. Check the exact pack's ingredients and precautionary statements: for example, ASDA Plant Based Soya Unsweetened declares soya and says it may contain nuts.
What should I check besides protein if I use soya drink regularly?
Check the current carton for sugars and any stated fortification that matters to your choice, such as calcium, iodine, vitamin D and vitamin B12. ASDA Plant Based Soya Unsweetened and M&S Plant Kitchen Soya Drink list these additions, but their nutrition figures use different stated bases, so read each label before comparing them.
