What to check before buying
Start with how you will carry the carton, then compare its ingredient list and nutrition information with what you want from the snack.
| Priority | What to check | Your needs |
| Storage |
Read the unopened-carton instructions and the refrigeration temperature and time limit after opening. Asda lists ambient storage before opening and use within five days after opening for Alpro; the Joybuy Plenish listing specifies a cool, dry place before opening and refrigeration at 0°C to 6°C for up to four days afterwards. |
I want to pack an unopened carton before leaving home, but I will need a way to refrigerate any leftovers as the label directs. |
| Nutrition label |
Compare figures on the same per-100ml basis and check the current pack. Asda lists 3.3g protein and 0g sugars for Alpro; Joybuy lists 3.2g protein and 0g sugars for Plenish. |
A drink that contributes protein fits my snack plans, but I do not want to assume the drink alone covers everything I need around exercise. |
| Snack timing |
Consider when you will eat and what else you will take. University College London Hospitals NHS Foundation Trust discusses carbohydrate-and-protein snacks before and after exercise; the appropriate choice varies with the activity. |
Before or after a session, I may want food alongside the drink rather than treating a carton as the whole snack. |
| Ingredients |
Check the organic designation and full ingredient list on the pack. The Joybuy Plenish listing names spring water and 8% organic soybeans; the Asda Alpro listing includes additional ingredients. |
A short recipe matters more to me than choosing between the two listed protein figures. |
| Allergens |
Check the pack’s allergen statement each time. Both drinks contain soya, and the cited Plenish listing also says it may contain nuts. |
If soya or nuts are relevant to me, I need the warning for the exact carton I am buying, not just its dairy-free description. |

Frequently asked questions
Can I carry an organic soya drink in my gym bag?
An unopened carton can be carried according to its pack instructions: Asda lists ambient storage before opening for Alpro Organic Soya No Sugars, while the Joybuy Plenish listing specifies a cool, dry place. Once opened, both need refrigeration; check the instructions for the exact carton.
Is a soya drink enough as a gym snack on its own?
Do not assume it is the whole snack for every session. University College London Hospitals NHS Foundation Trust discusses carbohydrate-and-protein snacks before and after exercise, so consider what food to take alongside the drink according to your activity and dietary needs.
Which of the two organic drinks has fewer listed ingredients?
Plenish Organic Unsweetened Soya lists spring water and 8% organic soybeans on its Joybuy page. The cited Asda listing for Alpro Organic Soya No Sugars includes other ingredients alongside its organic soya base, including calcium, flavourings and vitamins.
How do I check whether a soya drink is organic?
Look for the organic designation and certification information on the exact pack. A description such as plant-based or dairy-free does not, by itself, establish organic status.
Are these drinks suitable for someone with a soya allergy?
No. Both shortlisted drinks contain soya, and the cited Plenish listing also says it may contain nuts. Check the allergen declaration on the current pack before buying.
