Lutein is a dietary carotenoid present in eggs and yellow fruits and vegetables, exhibiting a variety of biological activities. At a concentration of 10 μM, it reduces mitochondrial DNA damage and the generation of reactive oxygen species (ROS) caused by hyperglycemia, and promotes mitochondrial biogenesis in ARPE-19 cells.
