About this ingredient
Lutein is a naturally occurring carotenoid belonging to the xanthophyll family. Unlike beta-carotene, lutein is not primarily used by the body as a vitamin A precursor. It is obtained from foods and is widely used as a nutritional supplement ingredient.
Lutein and zeaxanthin are important components of the macular pigment in the human eye. Their location in the retina has made them a major focus of nutritional research involving visual and retinal health.
The strongest clinical evidence for supplemental lutein relates to specific AREDS2 formulations for people with age-related macular degeneration at elevated risk of progression. This should not be interpreted as evidence that ordinary lutein supplements prevent or treat every type of eye condition.
Lutein is also valued for its antioxidant properties and is commonly included in multivitamins, eye-health formulas and carotenoid supplements.
