Lutein is a powerful antioxidant known for its eye health benefits and other physiological functions. Found naturally in marigold extract, leafy greens, and eggs, lutein is widely used in supplements, food coloring, and medicine. But what exactly does lutein do, and why should you include it in your daily routine?
This article explores lutein’s function, health benefits, applications, and market trends to help you understand its importance.
Lutein is a carotenoid, a type of plant pigment responsible for the yellow, orange, and red colors in fruits and vegetables. It belongs to the same family as beta-carotene and is often extracted from marigold flowers for use in supplements.
Lutein is not a vitamin, but it functions as an antioxidant. It helps protect cells from oxidative stress and supports various bodily functions, especially eye health.
Some of the richest sources of lutein include:
Leafy greens (spinach, kale, collard greens)
Egg yolks
Corn
Carrots
Marigold extract-based supplements
Lutein is primarily extracted from marigold flowers, which are processed to obtain lutein oil for use in dietary supplements and food additives.

Age-related macular degeneration (AMD)
Cataracts
Digital eye strain from screens
