An unsweetened, fortified soya drink can be a dairy-free choice when cow’s milk must be avoided and soya is tolerated. If soya must also be avoided, choose a non-soya alternative instead; for a child using a plant drink regularly, check its nutrition and discuss the choice with the clinician or dietitian managing the allergy.
The deciding distinction is whether the person avoiding cow’s milk can also have soya.
A soya drink may work for cereal, drinks or cooking. If it will be used regularly, compare unsweetened options and their calcium, iodine, vitamin D and vitamin B12 fortification, then check the current carton’s ingredients.
North West Knowledge Now NHS guidance for children aged one or over with cow’s-milk protein allergy discusses unsweetened, fortified soya drinks, but notes that some children may not tolerate soya. The child’s age, allergy plan and the drink’s protein, energy and fortification all matter.
A soya drink is not an option if soya must be avoided, even when it is dairy-free. Cambridge University Hospitals NHS Foundation Trust advises a milk-free and soya-free diet where a child has, or is suspected to have, both allergies. Check the ingredients of a non-soya alternative and seek individual dietetic advice for a restrictive diet.
Establish which allergens must be avoided before comparing fortification, protein and sugars on the same per-100 ml basis.
Consider when: Cow’s milk must be avoided, soya is tolerated and the drink will be used regularly.
Keep in mind: Soya is itself an allergen; for children, suitability also depends on age and individual allergy advice.
Consider when: Both milk and soya must be avoided, or soya tolerance is uncertain.
Keep in mind: Plant drinks differ in protein, energy and fortification. North West Knowledge Now NHS guidance highlights these differences when choosing for a child aged one or over.
| Priority | What to check | Your needs |
|---|---|---|
| Allergens | Read the current ingredients and highlighted allergens for milk and soya. Check any precautionary statement separately from the ingredients list. | I need to avoid the allergen that affects me, not just find a carton labelled dairy-free. If soya is one of my triggers, I need a non-soya drink. |
| Regular use | Compare calcium, iodine, vitamin D and vitamin B12 fortification, plus protein and energy per 100 ml. For a child, check the age guidance and the individual allergy plan. | If this drink will regularly replace cow’s milk for my child, its nutrition and suitability matter as well as its ingredients. North West Knowledge Now NHS guidance for children aged one or over favours unsweetened, fortified soya or pea options where appropriate. |
| Sugars | Check whether the drink is unsweetened and compare sugars per 100 ml; a front-of-pack description is not a substitute for the nutrition table. | For everyday cereal or hot drinks, I may prefer an unsweetened option. I still need it to meet my allergen requirements. |
| Precautionary labels | Distinguish a listed ingredient from a “may contain” statement about possible unintended presence. Follow the individual allergy-management plan when interpreting the latter. | A “may contain” warning leaves me with a different question from an ingredient declaration. Food Standards Agency research describes precautionary allergen labelling as communicating possible unintended allergen presence, not a measured amount. |
A soya drink still contains soya. Cambridge University Hospitals NHS Foundation Trust identifies soya milk as a food to avoid on a milk-free and soya-free diet.
Choose soya only when it is tolerated. If both allergens must be avoided, check a non-soya drink’s current ingredients instead.
Those descriptions do not identify every allergen relevant to an individual shopper, and recipes can change.
Read the ingredients and allergen information on the current carton each time you buy, even if you have used the product before.
Plant drinks differ in protein, energy and micronutrients. North West Knowledge Now NHS guidance considers these differences for children aged one or over with cow’s-milk protein allergy.
Compare the nutrition and fortification on the pack, and discuss a medically managed or restrictive diet with the child’s clinician or dietitian.
Food Standards Agency research describes precautionary allergen labelling as a warning about possible unintended allergen presence; it does not give a quantity.
Use the individual allergy-management plan and ask the relevant clinician or dietitian how to handle precautionary statements.
These named drinks provide starting points for checking current packs, not assurances that every product in a brand’s range has the same ingredients.
Tesco Soya Drink Unsweetened is an own-label option for shoppers comparing fortified soya drinks.
Alpro offers differently named soya drinks, so Original and No Sugars should not be treated as the same variant.
Waitrose Essential Unsweetened Soya Drink is a long-life option; Waitrose also has a separate soya-free shopping category.
M&S Plant Kitchen Unsweetened Soya Drink is a named option to assess when comparing drinks for someone who tolerates soya.
Sainsbury’s Unsweetened Soya Drink is another named supermarket option for comparing current labels.
These Joybuy options are soya drinks for shoppers who can have soya, including unsweetened and individually portioned formats. Their labels still need checking against the particular milk-allergy requirements before purchase.

No. Dairy-free does not mean soya-free or address every other allergen. Read the current ingredients and allergen information for the person’s particular allergy; Cambridge University Hospitals NHS Foundation Trust identifies soya milk as unsuitable on a milk-free and soya-free diet.
Compare the current pack’s calcium, iodine, vitamin D and vitamin B12 fortification, then protein, energy and sugars on a consistent per-100 ml basis.

Do not assume that every product is suitable. Waitrose & Partners states that its Essential Unsweetened Soya Drink is not suitable for children under two; check the specific product’s age guidance and discuss a child’s milk alternative with the clinician or dietitian managing their allergy.
It is a precautionary statement about possible unintended allergen presence, not an ingredient declaration or a stated quantity. Food Standards Agency research describes this purpose of precautionary allergen labelling; follow the individual allergy-management plan and seek clinical or dietetic advice if the statement affects the choice.
