If calories and fat are your main filters, Oatly Low-Cal Edition lists 20 kcal and 0.8 g fat per 100 ml; a no-sugars label answers a different question, as Alpro Oat No Sugars lists 0 g sugars but 1.5 g fat per 100 ml. For a drink you use regularly in a one- or two-person household, also check the exact carton’s added nutrients, protein, pack size and storage instructions.
For a smaller household, the useful comparison is between the drinks you will actually use, the size of the pack and what each carton provides per 100 ml.
If oat drink goes into cereal, tea or coffee most days, compare the per-100-ml figures rather than the wording on the front. Sainsbury’s lists 20 kcal and 0.8 g fat for Oatly Low-Cal Edition, while its own Oat Drink lists 39 kcal and 1.3 g fat per 100 ml.
If it is a regular part of breakfast and drinks, check the exact variant for calcium, iodine and added vitamins, then read its protein figure separately. Fortification and protein differ between named oat drinks, even within a brand’s range.
A drink chosen for its nutrition label also needs to work in the cup. Sainsbury’s advises letting hot water cool slightly before adding its Oat Drink to reduce separation; Oatly positions its Semi variant for tea and coffee. Check the instructions for the carton you choose.
Start with nutrition per 100 ml, then check whether the carton suits your usual drinks and how quickly your household will use it after opening.
| Priority | What to check | Your needs |
|---|---|---|
| Calories, fat and sugars | Compare all three figures per 100 ml on the exact variant. Sainsbury’s lists 20 kcal, 0.8 g fat and less than 0.1 g sugars for Oatly Low-Cal Edition; Alpro UK lists 0 g sugars but 1.5 g fat for Alpro Oat No Sugars. | I want to compare what is in the drink, not assume that “low-cal”, “semi” and “no sugars” mean the same thing. |
| Added nutrients | Look for calcium, iodine and vitamins D and B12 on the particular carton. Alpro UK lists 120 mg calcium and 22.6 µg iodine per 100 ml for its Oat No Sugars drink; do not transfer those figures to another variant. | If oat drink regularly replaces dairy in my routine, I want to know which nutrients my chosen carton actually lists. |
| Protein | Read protein per 100 ml separately from the fat figure. Sainsbury’s lists less than 0.1 g for Oatly Low-Cal Edition, while Oatly lists 1.1 g for its chilled Semi variant. | Protein matters to me when oat drink is a regular part of breakfast; a lower fat figure does not tell me its protein content. |
| Allergens and gluten | Check the exact allergen statement and any gluten-free claim. The Food Standards Agency defines “gluten-free” as no more than 20 mg/kg gluten in the food as sold to the final consumer. | Someone in my household needs me to check the label rather than assume every oat drink is suitable. |
| Pack size and storage | Check the number of cartons, their size and the instructions after opening. Sainsbury’s says to refrigerate its Long Life Oat Drink once opened and use it within three days; other cartons may give different instructions. | With one or two people using the drink, I need a pack size and an opened-carton period that fit our routine. |
| Hot drinks | Read any preparation guidance if the drink is mainly for tea or coffee. Sainsbury’s advises cooling hot water slightly before adding its Oat Drink to reduce separation. | Most of my oat drink goes into hot drinks, so the carton’s preparation advice matters as much as its name. |
These names describe different features. A drink with no sugars need not have the lowest calorie or fat figure among the cartons you are comparing.
Read calories, fat, sugars and protein per 100 ml together before choosing a variant.
Protein differs even between the named oat drinks here: Sainsbury’s lists less than 0.1 g per 100 ml for Oatly Low-Cal Edition, while Oatly lists 1.1 g for its chilled Semi variant.
If the drink is a regular part of your meals, check its protein line independently of its fat line.
A brand name alone does not establish which nutrients are added to a particular carton.
Check the exact product for calcium, iodine and vitamins D and B12 if those details affect your choice.
“Oat” does not establish a product’s gluten-free status, and oats also require attention on an allergen label.
Check the specific carton’s allergen declaration and gluten-free claim rather than relying on the category name.
These are references for named UK oat-drink variants, not claims about every product from each brand or what is available in the Joybuy selection below.
Oatly’s chilled Semi and Low-Cal Edition answer different questions: the former is positioned by Oatly for everyday uses including tea and coffee, while the latter has a lower listed calorie and fat figure.

An eight-carton pack calls for storage space in a smaller household. Joybuy lists 1.2 g fat, 0 g sugars and 0.9 g protein per 100 ml for this product; check its carton for the added-nutrient amounts and instructions after opening.

This six-carton pack is an option if you want to compare Oatly’s No Sugars variant with other oat drinks. Allow for the carton count, and read this product’s per-100-ml nutrition, added nutrients and storage directions rather than using figures from Oatly Semi or Low-Cal Edition.

This coffee-focused variant comes as eight 1L cartons. If you also want it as an everyday lower-fat drink, compare its per-100-ml fat and sugars with the other cartons, and check the preparation and after-opening directions.
No: compare the three per-100-ml figures separately. Sainsbury’s lists 20 kcal, 0.8 g fat and less than 0.1 g sugars for Oatly Low-Cal Edition, but 39 kcal, 1.3 g fat and 4.2 g sugars for its own Oat Drink; Alpro UK lists 0 g sugars and 1.5 g fat for Alpro Oat No Sugars.
Check the exact carton for calcium, iodine and added vitamins D and B12, and read protein separately. For example, Alpro UK lists 120 mg calcium, 22.6 µg iodine and 0.8 g protein per 100 ml for Oat No Sugars Drink; another variant may differ.
No; check the specific product’s gluten-free claim and allergen statement. The Food Standards Agency defines “gluten-free” as no more than 20 mg/kg gluten in the food as sold to the final consumer, and oats still need attention as an allergen.
It can, depending on the product and preparation. Sainsbury’s advises letting hot water cool slightly before adding its Oat Drink to reduce separation, so check your chosen carton’s hot-drink guidance.
Follow the instructions on the exact carton rather than treating “long-life” as an after-opening instruction. Sainsbury’s says to refrigerate its Long Life Oat Drink once opened and use it within three days; check other products individually.
