    Test Description

    Lutein

    Lutein is one of a few carotenoids selectively accumulated in the central area of the retina called the macula. The macula is responsible for supporting the health of the eye’s photoreceptor cell layer. Lutein is considered a dietary xanthophyll that helps support visual health.
