Gluten Free Oat Milk Brands in the UK

Is oat milk typically gluten free?

Oats do not naturally contain gluten, HOWEVER, they are commonly grown and processed alongside gluten containing cereals and as such are not usually gluten free.

An oat milk is only gluten free if the oats used have been grown and processed in isolation.

The list below explores which UK brands of oat milk are gluten free and which are not. You may be surprised how few are gluten free!

Gluten free vs. low gluten

An oat milk is classified as "gluten free" if it contains less than 20PPM (parts per million) of gluten.

An oat milk is deemed "low gluten" if it contains between 20 and 100 PPM of gluten. Those wanting to minimise gluten should opt for certified gluten free oat milk.

How to know if oat milk contains gluten?

The main way to check if oat milk contains gluten is to check the label. Look for the allergens section next to the ingredients list.

If nothing is mentioned under allergens, but the oat milk isn’t specifically marked as “gluten free” it’s probably best to avoid it just to be safe.

Frustratingly lots of supermarkets still provide no gluten information on product pages, so it can often be difficult to know. Remember that if oat milk is marked as “low gluten”, this is different from “gluten free”.


Please don't rely on this information exclusively when selecting a gluten free oat milk as ingredients and formulas may change. Always check the packaging!
