For a new parent choosing soya milk for their own use, compare unsweetened cartons by their fat and sugar figures and check fortification rather than choosing by the front of the pack alone. NHS breastfeeding guidance recommends calcium- and vitamin D-fortified dairy alternatives, with iodine particularly important to check for a vegan diet. An ordinary low-fat soya drink must not replace breast milk or infant formula as a baby’s main milk drink before age one; a drink for an older child needs a separate age and allergy check.
If soya drink is going into your cereal, tea or cooking, compare the carton’s fat and sugar figures alongside its fortification. NHS breastfeeding guidance recommends a varied diet and calcium- and vitamin D-fortified dairy alternatives, with iodine to check particularly if you follow a vegan diet.
A carton suitable for an adult is not automatically suitable as a child’s main milk drink. North East London NHS Foundation Trust says plant-based drinks should not replace breast milk or formula as the main drink before age one; for an older child, check age guidance, fortification, allergens and the child’s wider diet.
Per-100ml nutrition figures make most cartons easier to compare, but storage instructions and allergen warnings also matter when choosing a format your household will use. Keep M&S figures stated per 100g separate from products labelled per 100ml rather than treating the measures as identical.
Start with who will drink the soya milk, then compare the current cartons’ nutrition labels and instructions for that use.
| Priority | What to check | Your needs |
|---|---|---|
| Fat and sugars | Compare fat and sugars using the same stated measure, usually per 100ml. Read the energy figure as well; an unsweetened name does not tell you the fat content. | I’m choosing a drink for my own cereal or hot drinks and want to compare lower-fat, lower-sugar options without assuming they suit everyone in the household. NHS breastfeeding guidance advises lower-fat and lower-sugar dairy alternatives where possible. |
| Fortification | Look for listed calcium and vitamin D, and check iodine when relevant to your diet. Check vitamin B12 if you follow a vegan diet; compare protein using the carton’s stated measure. | If soya drink replaces dairy in my meals, I want to know which nutrients the particular carton lists. NHS breastfeeding guidance identifies calcium and vitamin D fortification and highlights iodine for vegan diets. |
| Child’s age and use | Read the carton’s age guidance. Distinguish use in weaning foods from use as a child’s main milk drink, and consider the child’s wider diet. | Is this for me, for food prepared for a baby, or for an older child’s main drink? North East London NHS Foundation Trust says plant-based drinks can be introduced in weaning from six months but must not replace breast milk or formula as the main drink before age one. |
| Allergens | Read the current ingredients and allergen statement for soya. Check any nut or peanut warning against the needs of the person who will drink it. | Someone in my household needs an allergen check, so I need the warning on this carton rather than an assumption about soya drinks generally. ASDA lists soya and a possible-nuts warning for its unsweetened drink; M&S warns that its listed drink is unsuitable for people with nut or peanut allergy. |
| Pack and storage | Check the pack quantity, whether it is chilled or long-life, and the refrigeration and use instructions after opening. | A larger pack only works for us if we can use the opened cartons within their individual storage instructions. |
An ordinary soya drink is not a substitute for breast milk or infant formula as a baby’s main drink before age one, according to North East London NHS Foundation Trust.
Keep the adult carton for the parent’s use or age-appropriate food preparation. If a baby needs an alternative to their usual milk, seek advice appropriate to that baby’s circumstances.
Fat, sugars, protein and fortification differ between cartons. For example, ASDA lists 1.1g fat and 2.0g protein per 100ml for its unsweetened soya drink, while Alpro UK lists 1.9g fat and 3.3g protein per 100ml for Soya No Sugars Drink 1L.
Compare the current labels on the same stated basis and check the nutrients that matter for the intended drinker.
A dairy-free drink can still contain soya or carry a nut warning. ASDA’s listed unsweetened drink declares soya and may contain nuts; M&S says its unsweetened drink is unsuitable for people with nut or peanut allergy.
Read the current carton’s ingredients and warnings before giving it to anyone managing an allergy.
Opened-carton instructions differ: M&S and Waitrose specify three days for their listed drinks, while the Joybuy description for the Alpro 8 x 1L pack specifies five days refrigerated.
Match the pack quantity to household use, refrigerate opened cartons and follow the instructions on each carton.
These examples show why it is worth comparing particular cartons, not assuming every drink from a brand has the same recipe or age guidance.
Alpro UK lists Soya No Sugars Drink 1L as a long-life option with 0g sugars, 1.9g fat and 3.3g protein per 100ml.
Tesco Groceries lists both Tesco Longlife Soya Drink Unsweetened and Tesco Soya Drink Unsweetened.
Sainsbury’s Unsweetened Soya Drink 1L lists 1.3g fat, less than 0.5g sugars, 2.2g protein and 120mg calcium per 100ml.
Plant Based by ASDA Unsweetened Soya 1 Litre lists 1.1g fat, 19kcal and 2.0g protein per 100ml.
M&S Unsweetened Soya Drink lists 1.4g fat, 0.4g sugars and 2.8g protein per 100g.
Waitrose & Partners lists 1.9g fat, 0g sugars, 3.4g protein and 120mg calcium per 100ml for Essential Unsweetened Soya Drink.
These Alpro soya drink listings are options to consider for an adult’s everyday use. Check each current carton’s fat figure, fortification, allergen statement and age guidance before deciding whether it meets your household’s needs.

The 8 x 1L long-life pack is an option for a parent using soya drink in cereal or cooking. Joybuy lists calcium and vitamins B2, B12 and D for this pack; check its current carton for fat, iodine, allergens and opened-carton instructions. It is not an infant-formula substitute.

This Alpro soya drink listing is another option for an adult’s cereal or hot drinks. Compare the current carton’s fat and sugar figures, fortification and allergen statement before choosing it; check its age guidance separately if the drink is intended for a child.
Yes, for your own diet: NHS breastfeeding guidance advises choosing lower-fat and lower-sugar dairy alternatives where possible as part of a varied diet. Check that the drink is fortified with calcium and vitamin D, and check iodine particularly if you follow a vegan diet. This advice is not a reason to give an adult soya drink to a baby as their main milk.
No, not as the main milk drink before age one. North East London NHS Foundation Trust says plant-based drinks can be introduced in weaning foods from six months but should not replace breast milk or infant formula as the main drink until the child is one. Seek individual advice if a baby needs an alternative because of allergy or another feeding concern.
Check the carton’s age guidance, allergens and whether it is unsweetened and fortified, then consider its protein and energy figures alongside the child’s full diet. North West Knowledge Now NHS guidance identifies unsweetened, fortified soya and pea drinks as plant-based options for children aged one or over with cow’s-milk protein allergy, while noting that soya may not suit some of those children.
Follow the instructions on that carton and refrigerate it after opening. The listed M&S and Waitrose drinks specify three days; the Joybuy description for Alpro Soya No Sugars Long Life Drink 8 x 1L specifies five days. Do not apply one product’s instruction to another.
Do not give a soya drink to someone with a confirmed soya allergy. Read the current ingredients and precautionary warnings for the particular carton, including any nut or peanut warning. If you think someone is having an anaphylactic reaction, NHS advice is to call 999.
