Lutein is a natural pigment and carotenoid that belongs to the xanthophyll family. It is found abundantly in various fruits and vegetables , especially dark leafy greens such as spinach and kale , as well as in egg yolks and some types of algae . Lutein is known for its deep yellow color and its essential role in maintaining healthy vision .
One of the primary functions of lutein is to support eye health . It is a key component of macular pigment , a protective layer located in the central part of the retina called the macula . Macular pigment acts as a natural filter , absorbing harmful blue light and protecting the delicate photoreceptor cells in the retina from oxidative damage. By protecting the eyes from excessive blue light and reducing oxidative stress, lutein helps maintain the integrity of the macula and supports optimal visual function. It absorbs free radicals and helps neutralize their harmful effects on cells and tissues in the eye. In addition to its role in eye health, lutein has been linked to other potential benefits.
Lutein is a fat - soluble nutrient, which means it is better absorbed when consumed with fat in the diet . Therefore, for optimal absorption, it is recommended to consume foods rich in lutein or lutein supplements along with a source of healthy fats. While lutein can be obtained through a balanced diet , some individuals may benefit from lutein supplements to ensure adequate intake, especially if their diet lacks sufficient lutein-rich foods.
