The present invention relates generally to the field of beverages. In particular, the present invention relates to the field of beverages fortified with iron. For example, the present inventors have found that iron fortification with ferrous bisglycinate in a red plant based beverage with a pH in the range of 3.5 to 4.0 leads to an increased colour stability and a better taste of the beverage compared to other compounds commonly used to fortify beverages with iron.
