Doctor's Best Lutein 20mg Lutein Esters, 120 CT

It has been well established that lutein and zeaxanthin are present in high concentrations in the retinal tissue of the human eye. Epidemiologic research and the majority of clinical studies infer that a higher intake of these two xanthophylls is associated with a superior level of eye health. In a study of 376 individuals (ages 18-75), blood nutrient levels were analyzed alongside lens optical density (LOD) and macular pigment optical density (MPOD) measurements to find out which nutrients may be beneficial for these markers of eye health as we age. MPOD is associated with blood levels of lutein and can be altered with dietary intake of xanthophylls. Due to the inverse relationship found between MPOD and LOD, the researchers determined that lutein and zeaxanthin intake supports maintenance of healthy eye lenses with age.
