For a regular vegan dairy alternative that can be kept in the cupboard before opening, look for a UHT soya drink labelled suitable for vegans, then check its current carton for calcium, vitamin D, vitamin B12 and iodine. Compare the sugars line if you want an unsweetened drink, and check allergens and after-opening storage separately: neither a vegan label nor UHT treatment answers those questions.
If you use soya drink in cereal, cooking or hot drinks, check the individual carton’s fortification and sugars rather than assuming all plant drinks have the same composition. The NHS recommends including fortified dairy alternatives, such as soya drinks, in a vegan diet.
A UHT or long-life label helps you identify a drink intended for storage before opening. If you also want no sugars, compare that claim with the nutrition panel and follow the carton’s separate instructions once opened.
Check age-specific wording on the exact product. Sainsbury’s says its unsweetened soya drink can form part of a balanced diet from age one but is not suitable as a main milk alternative for children under two; Waitrose says its Essential Unsweetened Soya Drink is not suitable for children under two.
Start with the carton’s vegan and long-life wording, then compare nutrition and allergen details for the way you plan to use the drink.
| Priority | What to check | Your needs |
|---|---|---|
| Fortification | Look for calcium, vitamin D, vitamin B12 and iodine on the exact carton. The UK SACN and COT assessment says plant drinks vary considerably in nutrient content and that UK organic plant drinks cannot be fortified with nutrients. | If I use soya drink regularly instead of dairy milk, I want to know which nutrients this particular drink lists, not rely on its vegan or organic wording. |
| Sugars | Read the ‘of which sugars’ value on the nutrition panel, using the same quantity basis when comparing cartons. Check whether the product is labelled unsweetened or no sugars. | For cereal or cooking, I may prefer a drink without the sweetness of a sweetened option. |
| Vegan and allergen labels | Check the vegan statement, ingredients, highlighted allergens and any ‘may contain’ wording separately. GOV.UK warns that vegan labelling does not guarantee the absence of animal-origin allergens through cross-contact. | I need a drink suitable for vegan shopping, but if someone also has an allergy, I cannot use ‘vegan’ as a substitute for allergen information. |
| Storage | Confirm that the carton says UHT or long-life. Read its refrigeration and use-within instructions for after opening; unopened and opened storage are different. | I want cartons I can keep unopened in the cupboard, with a size I can use according to the instructions once opened. |
| Use for children | Read the exact product’s age and main-drink guidance. Sainsbury’s and Waitrose give different product-specific wording for young children. | If I am buying for a child under two, I need to check whether this particular drink is suitable at all and whether it can be used as a main milk alternative. |
The UK SACN and COT assessment says nutrient content varies considerably between plant drinks; UK organic plant drinks cannot be fortified with nutrients.
If fortification matters to your choice, compare calcium, vitamin D, vitamin B12 and iodine on the current carton.
GOV.UK says vegan labelling does not guarantee that animal-origin allergens are absent through cross-contact. Soya itself is an allergen that must be declared when used as an ingredient.
Read the ingredients and precautionary allergen statements for the person who will drink it.
‘Plant-based’ does not tell you the sugars value of a particular soya drink.
If sweetness matters, compare the ‘of which sugars’ line on the nutrition panels using the same quantity basis.
Long-life treatment describes storage before opening; opened cartons have their own refrigeration and use-within instructions.
Follow the directions on your carton and choose a size you can use within its stated period.
These examples illustrate label differences between named drinks; check the exact carton rather than applying one product’s details to a whole brand.

For vegan shoppers wanting an unopened long-life carton, this listing describes a vegan UHT soya drink. It states 0g sugars and 3.3g protein per 100ml, and lists water and hulled soya beans among its ingredients. It contains soya; check the carton for calcium, vitamin D, vitamin B12 and iodine, and confirm what the ‘6’ in the listing includes. Refrigerate after opening and follow its stated five-day use period.
No. GOV.UK says vegan labelling does not guarantee the absence of animal-origin allergens through cross-contact. Check the ingredients, any ‘may contain’ statement and whether the product gives the allergen assurance you need.
Yes. GOV.UK identifies soya beans among the allergens that must be clearly labelled in the ingredients list when used in a prepacked food or drink.
Check the current carton for calcium, vitamin D, vitamin B12 and iodine, alongside its sugars value. The NHS recommends fortified dairy alternatives such as soya drinks in a vegan diet, while the UK SACN and COT assessment says nutrient content varies between plant drinks.
Do not assume so: Sainsbury’s says its unsweetened soya drink can form part of a balanced diet from age one but is not suitable as a main milk alternative for children under two. Waitrose warns that its Essential Unsweetened Soya Drink is not suitable for children under two. Check the exact product’s age guidance.
No—follow the carton’s after-opening instructions. For example, M&S says to refrigerate its Plant Kitchen Soya Drink after opening and consume it within three days; another product may give a different period.
