Lutein is an antioxidant and one of 600 naturally occurring carotenoids, which are the yellow, orange and red organic pigments produced by plants, algae, bacteria and fungi. Lutein is also what gives plants like pumpkins, corn, carrots and even salmon and shrimp their characteristic colors. Lutein is synthesized only by plants and is found in high quantities in green leafy vegetables like spinach and kale. When ingested by humans, lutein may bioaccumulate in the eyes where it is thought to reduce oxidative stress, as well as affect immune responses and inflammation. Lutein is also believed to impact brain function, filter blue light and increase pigment density in the eyes.*
