For a household top-up, choose individually sealed portions in a size you expect to finish after opening: several long-life 1L cartons suit regular use, while smaller cartons may suit occasional servings. If soya drink regularly replaces dairy, compare fortification on the exact product; also check its sugar declaration, allergy warnings and opened-carton instructions rather than assuming a multipack settles those choices.
Long-life cartons can be kept unopened as directed on the pack. Plan how many to buy around how quickly you finish each opened carton: the cited Waitrose Essential and M&S drinks specify three days after opening, while the cited Alpro drink specifies five.
Compare the fortification and nutrition information on the exact variant. The UK government’s 2025 SACN and COT assessment says nutrient content varies considerably between plant-based drinks and identifies calcium, iodine, riboflavin and vitamin B12 among its fortification considerations.
Check the sugars figure as well as the words on the front of the carton. A short ingredient list and added nutrients are different priorities: the UK government’s SACN and COT assessment states that organic plant-based drinks in the UK cannot be fortified with nutrients.
Start with the portion size your household will use, then compare the exact variants for nutrition, storage and allergy information.
| Priority | What to check | Your needs |
|---|---|---|
| Pack format | Check the number and size of sealed cartons or bottles. A multipack of small portions serves a different pattern of use from several 1L cartons. | We get through a full-size carton regularly, or we only want to open a small portion at a time. |
| Fortification | Read the exact carton’s ingredients and nutrition panel for added calcium, iodine and vitamins. The UK government’s 2025 SACN and COT assessment says plant-based drinks vary considerably in nutrient content. | If soya drink regularly replaces dairy in our household, I want to know what the particular variant contains rather than rely on its brand or pack size. |
| Sugars | Compare the declared sugars per 100ml and distinguish sweetened, unsweetened and no-sugars variants. Tesco Groceries lists both sweetened and unsweetened Tesco long-life soya drinks. | I want an unsweetened drink for everyday use, or I want to compare the sugar declarations of the flavours we buy. |
| Storage after opening | Follow the refrigeration and use-period instructions on each pack. Waitrose & Partners states three days after opening for Essential Unsweetened and five for the cited Alpro No Sugars drink; M&S states three for its cited unsweetened drink. | Several sealed cartons work for us, but I do not want to open more than we can finish within each carton’s stated period. |
| Allergy and age warnings | Read the current product label for soy and any further warnings. UK government allergen guidance lists soybeans as an allergen; the cited M&S drink also carries nut- and peanut-allergy unsuitability statements. | Someone in our household has an allergy, or the drink is for a young child, so I need to check the exact carton before serving it. |
| Ingredients | Compare the ingredient list with the fortification list. Waitrose & Partners lists water and organic soybeans for its cited Plenish organic drink; the UK government’s SACN and COT assessment says UK organic plant-based drinks cannot be fortified. | A short ingredient list matters to me, but I would consider that choice separately from whether the drink contains added nutrients. |
Unsweetened and plant-based labels do not tell you which nutrients have been added. The UK government’s SACN and COT assessment reports considerable variation in the nutrient content of plant-based drinks.
If the drink regularly replaces dairy, compare the ingredients and nutrition information on each variant before buying several cartons.
Long-life describes the unopened product, not how long it keeps after opening. Waitrose & Partners and M&S specify three days for their cited unsweetened drinks; Waitrose & Partners specifies five days for the cited Alpro No Sugars drink.
Keep unopened cartons sealed until needed, follow the refrigeration instructions and note when you open each one.
The UK government’s SACN and COT assessment states that UK organic plant-based drinks cannot be fortified with nutrients. An organic drink with few ingredients therefore answers a different shopping preference from a fortified variant.
Choose between those features deliberately by reading the exact product’s ingredient and nutrition information.
UK government guidance lists soybeans as an allergen, and individual drinks can carry further warnings. The cited M&S Unsweetened Soya Drink says it is not suitable for people with nut or peanut allergy.
Check the current carton for everyone who will drink it, particularly when switching products or variants.
These examples describe particular soya drinks and ranges, not every variant sold under each name.
Waitrose & Partners lists an Alpro Soya Long Life No Sugar drink with added calcium, iodine and vitamins B2, B12 and D2.
Tesco Groceries lists 1L own-label long-life soya drinks in both unsweetened and sweetened variants.
Sainsbury's grocery results list an Unsweetened Long Life Soya Drink in a 1L format.
M&S lists a 1L Unsweetened Soya Drink fortified with calcium, iodine, vitamin D and vitamin B12.
Waitrose & Partners lists 1L Essential Unsweetened Soya Drink with added calcium, iodine and vitamins.
These options include a long-life 1L soya drink multipack and smaller ready-to-drink portions for household top-ups. Compare the pack sizes and the current labels for the needs that matter to you.

Eight full-size cartons suit a household that uses soya drink regularly. Refrigerate each carton after opening and use it within the stated five days; check the current carton for iodine if that fortification matters to you.
No image available
These smaller portions offer an alternative to opening a 1L carton for each serving. Check the current pack’s sugar and fortification information before choosing it for a particular dietary preference, and follow its instructions after opening.

Six malt-flavoured portions suit a smaller top-up than a large case. This is a sweetened drink, not an unsweetened alternative; check the current label for its sugar declaration, soy and barley allergens, and precise instructions after opening.
No image available
Six individual cartons offer smaller servings for a household top-up. This original variant is sweetened; compare its current sugar declaration with other variants, and check the carton if a quantified calcium value matters to your choice.
No image available
Three smaller portions suit a limited top-up rather than a case of 1L cartons. This is a sweetened drink; check its current sugar and soy-allergen information and follow the package directions after opening.
Choose the sealed portion size that matches how your household uses the drink. Several long-life 1L cartons can be opened one at a time for regular use; smaller portions may suit occasional servings. Check the opened-carton period on the exact product before deciding how many to buy.
Check the exact drink’s fortification and nutrition information rather than relying on the words ‘soya’ or ‘plant-based’. The UK government’s 2025 SACN and COT assessment says nutrient content varies considerably and discusses calcium, iodine, riboflavin and vitamin B12 in its fortification recommendations.
No. The UK government’s SACN and COT assessment states that organic plant-based drinks in the UK cannot be fortified with nutrients. If added nutrients matter to your choice, compare the ingredient and nutrition information rather than treating organic status as a substitute for fortification.
Do not assume every carton is suitable for every age: Waitrose & Partners says its cited Essential Unsweetened Soya Drink is not suitable for children under two years old. Read the exact product label and seek appropriate clinical or dietetic advice if the drink would replace milk for a young child or an allergy is involved.
Read the current carton’s soy declaration and any additional product-specific warnings. UK government allergen guidance lists soybeans as an allergen, while the cited M&S Unsweetened Soya Drink also states that it is not suitable for people with nut or peanut allergy.
