What Is LUTEIN?
Lutein is a carotenoid antioxidant that accumulates in the macula of the eye and various brain tissues, where it filters blue light and protects against oxidative damage. It is primarily obtained through dietary sources like leafy green vegetables, egg yolks, and supplements, and is well-established for supporting eye health, cognitive function, and reducing inflammation.
