Lutein is a naturally occurring carotenoid pigment belonging to the xanthophyll family, known for its vibrant yellow color and powerful antioxidant properties . It is a fat-soluble nutrient that is not produced by the body and must be obtained through diet or supplements. Lutein is particularly concentrated in the macula of the eye, where it acts as a filter, absorbing harmful blue light and protecting the macula from oxidative damage, which helps maintain healthy vision and prevent age-related macular degeneration (AMD) .
In addition to its role in eye health, lutein has been linked to various other health benefits. It exhibits anti-inflammatory properties, which can help mitigate chronic inflammation and potentially reduce the risk of conditions such as arthritis, diabetes, and cardiovascular disease . Lutein may also have a positive impact on cognitive function, with higher levels in the brain associated with improved cognitive performance, including memory, processing speed, and attention . Furthermore, it supports cardiovascular health by potentially reducing the risk of heart disease through the prevention of LDL cholesterol oxidation and promotion of endothelial function .
Lutein is found in various plants, including dark green leafy vegetables, egg yolks, and corn. It is commonly analyzed and quantified in foods or tissues via high-performance liquid chromatography (HPLC) . The recommended intake of lutein to achieve health benefits has been a topic of interest, with the suggestion that establishing dietary guidance would encourage the consumption of lutein-containing foods and raise public awareness about its potential health benefits .
