Standard original formulations of Oatly contain natural sugars produced during the enzymatic breakdown process of oats, alongside modest amounts depending on the specific product variant, though unsweetened options avoid added refined sugars. The natural conversion process transforms complex starches into simple sugars like maltose, which gives the liquid its characteristic sweetness but also contributes to higher total carbohydrate and sugar readings on nutrition labels compared to plain nut milks. Consumers monitoring blood sugar levels or restricting carbohydrate intake should carefully review specific product labels, as flavored varieties typically feature higher amounts of added sugars.
