    Lutein

    With meals containing fat

    Lutein is a xanthophyll carotenoid concentrated in dark leafy greens like kale and spinach, as well as egg yolks and marigold flowers. It selectively accumulates in the macula of the eye and in brain tissue, where it serves as both an antioxidant and a blue light filter. It is one of the most studied nutrients for long-term eye health preservation.
