Oatly Oat Drink Original

A short, mostly clean ingredient list with fortification and no added sugar, but its enzyme-created maltose gives it a surprisingly high sugar content for a plant milk.

Ingredient Breakdown

Calories
About 46 kcal per 100 ml (about 115 kcal per 250 ml glass). Formulations vary by country.
Serving
250 ml (1 glass)
Sugar
About 10 g per 250 ml (about 11% of the daily reference intake). All of it is formed from oat starch, none is added.
Sat. Fat
About 0.5 g per 250 ml (about 2.5% of the daily value)
Contains gluten-containing grain (oats). Unless a pack is labeled gluten-free, it is not suitable for coeliacs. Labeling varies by country.
The enzyme-formed maltose has a high glycemic index, so people managing blood sugar may prefer an unsweetened soy or almond drink.
Low in protein (about 1 g per 100 ml) compared with dairy or soy milk, so it is not an equivalent protein source.
Contains a phosphate additive (E340). People with kidney disease on phosphate restrictions should check with their doctor.
Formulations differ between countries (for example, US and EU versions), so check your local pack.
Full Analysis

Ingredients (7)

Oat base (water, oats 10%)

aka Oat milk base

Whole-grain oats are a good source of soluble fiber (beta-glucan), which is linked to cholesterol reduction. Oatly's process removes much of the fiber, but some remains.

Daily Intake — No intake concern. Provides about 1 g of fiber per serving, including some beta-glucan.
SAFE

Maltose (formed from oat starch during enzyme treatment)

Controversial
aka Natural oat sugar

It is not added sugar, but enzymes break oat starch into maltose, which has a high glycemic index. This matters for people managing blood sugar, though the total amount is moderate.

Daily Intake — About 10 g of sugars per 250 ml, around 11% of the 90 g EU reference intake.
MODERATE

Rapeseed oil (1.2%)

aka Canola oil

It is rich in unsaturated fats and low in saturated fat. It gives the drink a creamy texture without dairy fat.

Daily Intake — About 3 g of fat per serving, with very low saturated fat (about 0.5 g, roughly 2.5% of the daily limit).
SAFE

Dipotassium phosphate

E340 Controversial
aka Phosphate stabilizer

It is generally recognized as safe and keeps the drink from separating. High intake of phosphate additives is a concern for people with chronic kidney disease, though a glass of oat milk adds little.

Daily Intake — Small amount per serving. Mainly relevant for people on phosphate-restricted diets.
MODERATE

Calcium carbonate

E170
aka Chalk (calcium supplement)

It is a well-studied, safe calcium source. It is added so the drink is comparable to dairy milk for calcium.

Daily Intake — Provides about 120 mg of calcium per 100 ml, roughly 15% of the daily value per 100 ml.
SAFE

Salt

aka Table salt

The amount is low and used mainly for flavor balance. It is not a meaningful sodium source unless you drink a lot.

Daily Intake — About 0.25 g per serving, roughly 4% of the daily limit.
SAFE

Vitamins (D2, riboflavin/B2, B12)

aka Added vitamins

Fortification helps close the nutritional gap with dairy milk, especially B12 and D for people who eat little animal food. The amounts are safe.

Daily Intake — Contributes roughly 15% of the daily value of each fortified vitamin per 100 ml.

Fun Fact

Oatly's oat drink grew out of research at Lund University in Sweden, where food scientist Rickard Öste developed an enzyme process that turns oat starch into sugars and makes a milk-like liquid, originally to help people who are lactose intolerant.
