Choose a soya drink by the protein in the portion you will drink and what else you plan to eat, rather than relying on a front-of-pack protein claim alone. The British Heart Foundation says extra protein after exercise lasting longer than an hour can be useful; if lower sugar or regular use instead drives your choice, compare unsweetened drinks and their fortification too.
The useful comparison depends on whether the drink is the main part of your snack, something to have alongside food, or a regular alternative to dairy.
If you will not eat a meal soon, check how much protein your intended portion contributes and consider what food you will have with it. The British Heart Foundation says extra protein after a session lasting longer than an hour can be useful.
If you also use soya drink in smoothies or cereal, compare sweetened and unsweetened cartons using the sugars figure for the amount you normally pour.
Check the exact carton for calcium, iodine and listed vitamins. The UK Scientific Advisory Committee on Nutrition and Committee on Toxicity assessment says nutrient content varies considerably between plant-based drinks.
Start with your likely portion and next meal, then compare the nutrition panel and ingredients of the exact variant you are buying.
| Priority | What to check | Your needs |
|---|---|---|
| Protein contribution | Compare protein per 100ml or for the same-sized portion. Sainsbury's lists 12.5g per 250ml for its Sweetened High Protein Soya Drink; Waitrose lists 3.4g per 100ml for Essential Unsweetened. | If my next meal is some time away, I want to know what the drink contributes to the whole snack, not just whether its name mentions protein. |
| Sugars and portion | Read sugars per 100ml and for the portion you intend to drink. The reviewed Sainsbury's sweetened high-protein drink lists 7.2g per 250ml; Waitrose Essential Unsweetened lists 0g per 250ml. | I may want an unsweetened everyday drink, or I may choose a sweetened one; either way, the amount in my glass matters. |
| Fortification | Look for the named nutrients on the exact carton, particularly calcium, iodine and vitamins if you regularly replace dairy. The UK SACN/COT assessment notes considerable variation between plant-based drinks. | When soya drink is a regular dairy alternative for me, I do not want to assume every brand or variant has the same fortification. |
| Ingredients and allergens | Read the current ingredients and allergy statement. A dairy-free description does not make a soya drink suitable for someone with a soya allergy. | If I am buying for someone with an allergy, I need to check their exact carton rather than rely on a familiar product name. |
| Pack and storage | Check whether the pack contains individual cartons or larger bottles, and follow its directions after opening. | A single carton is easier to take to the gym; a larger pack makes more sense if I can pour a portion and store the rest as directed. |
Protein figures differ by product and portion. Sainsbury's lists 12.5g per 250ml for its Sweetened High Protein Soya Drink, while the reviewed Waitrose Essential Unsweetened drink lists 8.5g per 250ml.
Compare like-sized portions and decide what else will be in your post-gym snack.
The reviewed Sainsbury's high-protein drink is sweetened and lists 7.2g sugars per 250ml; Waitrose Essential Unsweetened lists 0g for the same portion.
Read both protein and sugars for the portion you expect to drink.
The UK SACN/COT assessment says organic plant-based drinks in the UK cannot be fortified with nutrients. Organic status therefore does not tell you that a drink contributes the calcium, iodine or vitamins you are looking for.
If fortification matters to your choice, check the nutrition panel of the specific carton.
Soya remains an allergen in a soya drink, and ingredients can differ between products and change over time.
Read the current ingredients and allergy statement, especially when buying for someone with a soya, nut or peanut allergy.
These examples help distinguish product types; the nutrition figures apply to the named drinks, not every product from a brand or retailer.
Alpro has standard, no-sugars and Plant Protein soya-drink variants for different uses.
Its Sweetened High Protein Soya Drink gives a stated protein figure for a 250ml serving.
Essential Unsweetened Soya Drink is an option for comparing an unsweetened drink with a high-protein variant.
The reviewed Unsweetened Soya Drink is a fortified option in this range.
Tesco lists Alpro High Protein Soya Original, providing another place to identify that branded variant.
These Joybuy options include larger Alpro packs and smaller ready-to-drink cartons. Choose a pack format that fits your snack plans, then check the current carton for nutrition, allergens and storage instructions.

Consider this larger-pack option if protein is a priority and you can portion the drink for your snack. The Alpro Plant Protein listing states 5g protein per 100ml; check the current carton for sugars and allergens.

Consider this larger pack if you want a no-sugars soya drink to portion into a post-gym snack or use at home. Check the current carton for its nutrition, allergens and after-opening storage directions.

The 300ml format may suit a snack you want to carry as one drink. Read the current carton if protein, sugars, allergens or storage after opening affect your choice.

The individual 250ml cartons may fit a snack taken away from home. Malted and unsweetened drinks are different choices, so check the current sugars figure and the allergy statement; the listing identifies soya and barley.

The six individual cartons offer a portioned format. Do not rely on the Low-Sugar wording when choosing for sugar content: check the current carton's sugars figure before buying. The drink contains soya.
A soya drink can be part of a snack, but its protein figure alone does not describe everything you will eat. The British Heart Foundation says extra protein after exercise lasting longer than an hour can be useful; check the drink's portion and consider your next meal or accompanying food.
Choose by the contribution you want from the drink. Sainsbury's lists 12.5g protein per 250ml for its Sweetened High Protein Soya Drink, while Waitrose Essential Unsweetened lists 8.5g protein and 0g sugars per 250ml. Compare both protein and sugars alongside the rest of your snack.
Check the exact product for its listed nutrients rather than assuming soya drinks have the same fortification. The UK SACN/COT assessment says plant-based drinks vary considerably in nutrient content and notes that UK organic plant-based drinks cannot be nutrient-fortified.
No: dairy-free does not mean free from soya. Check the current ingredients and allergy statement for the precise drink, including any other allergens relevant to the person who will have it.
Follow the after-opening directions on the individual carton, including refrigeration and any stated use-by period. Long-life packaging before opening does not mean the opened drink can be stored the same way.
