What should you check?
Start with the amount you use, then compare nutrition figures on the same stated basis. If vegan certification is a requirement, check that separately from the nutrition panel.
| Priority | What to check | Your needs |
| Energy and sugars |
Check kcal and sugars per 100ml or per serving, then calculate them for the quantity you pour. Keep figures stated per 100g distinct from those stated per 100ml. |
For a splash in tea or a larger cereal portion, I want to know what the amount I use adds to my overall intake. |
| Protein and fortification |
Compare protein on the same stated basis. If the drink regularly replaces dairy milk, check the carton for added calcium, iodine, vitamin D and B12 rather than assuming every soya drink contains them. |
I use soya drink regularly and want to consider its listed nutrients, not just its kcal. |
| Vegan certification |
Read the vegan claim and look for a named third-party certification mark if required. The Vegan Society’s Vegan Trademark is a separate scheme with annual renewal; vegan wording alone does not establish that a carton carries it. |
Is a vegan suitability statement enough for me, or do I specifically want a certified product? |
| Soya allergen |
Read the current ingredients and allergen statement, including any relevant precautionary wording. GOV.UK lists soya beans among the allergens that must be declared when present. |
If I have a soya allergy, vegan or dairy-free wording does not make this drink an option for me. |
Brand and retailer references
These examples show why the particular drink and its current label matter more than the brand name alone.
Alpro
Sainsbury’s describes Alpro Soya No Sugar Long Life Drink as plant-based and suitable for vegans, with no sugars and added calcium and vitamins B2, B12 and D.
- A named no-sugar, long-life soya option for comparison.

Sainsbury’s lists its Unsweetened Soya Drink at 26 kcal, less than 0.5g sugars and 2.2g protein per 100ml, with added calcium, iodine, vitamin D and B12.

- Its vegan statement and per-100g nutrition figures are available for a product-specific check.
- Do not compare its per-100g figures directly with another drink’s per-100ml figures or assume the vegan statement establishes third-party certification.

Frequently asked questions
Is vegan soya milk automatically suitable for weight loss?
No. NHS Better Health explains that weight loss requires using more energy than you take in overall. Check the drink’s labelled kcal in the amount you use, whether that is in a hot drink, cereal or a smoothie.
Does a vegan label mean a drink is Vegan Trademark certified?
No. GOV.UK says there is no legal definition of vegan food in UK law, although food labelling must be accurate and not misleading. The Vegan Society’s Vegan Trademark is a separate scheme; check the current carton for its mark if you require that certification.
What should I compare on an unsweetened soya-drink carton?
Compare kcal, sugars and protein on the same stated basis, then calculate them for your usual portion. If you use the drink regularly instead of dairy milk, also check which nutrients are listed as added; do not treat a figure per 100g as interchangeable with one per 100ml.
Can someone with a soya allergy drink vegan soya milk?
No. Vegan and dairy-free claims do not remove the soya allergen. GOV.UK lists soya beans among the allergens food businesses must declare when present; avoid soya drinks if you have a soya allergy.
How should I store soya drink after opening?
Follow the instructions on your carton. The reviewed Sainsbury’s Unsweetened Soya Drink and Waitrose Essential Unsweetened Soya Drink both specify refrigeration and use within three days after opening, but instructions for other products may differ.
