Lutein - See Why Lutein is So Important
Lutein is naturally found in healthy eyes, and since it is not made in the body, it must be obtained from dietary sources.** Research indicates that Lutein may act as a filter to protect the central area of the eye’s retina, called the macula, from potentially damaging forms of light.** Lutein nutritionally promotes and maintains eye health.** It also possesses antioxidant capabilities.**
Lutein is a member of the carotenoid family, a group of naturally occurring fat-soluble pigments found in plants. Lutein is the principal carotenoid present in the macula. The macula is responsible for supporting the health of the eye’s photoreceptor cell layer, which is why carotenoid levels are so important.**
Lutein Research - Blinded Study with Visible Results
Lutein has been shown to be beneficial to long term visual health. Seventeen participants were randomized in a double-blind study involving dietary supplementation with Lutein (15 mg), alpha-tocopherol (100 mg), or placebo, three times a week for up to two years.1 Visual performance, acuity and glare sensitivity were measured as parameters of vision health. In all parameters measured, subjects that consumed the Lutein had significant improvements in vision health when compared to the other groups.
In another recent placebo-controlled study, Lutein resulted in a significant improvement in eye pigment and optical density when compared to the placebo.2 The Lutein groups also significantly improved their visual acuity when compared to placebo.
