Measuring macular pigment offers potential as a biomarker of cognitive health, and Alzheimer’s patients are more likely to be seriously deficient in carotenoids, say data from two new studies.
Sustained supplementation with the macular carotenoids can lead to greater augmentation of macular pigment and improve contrast sensitivity, says a new study.
Two years of supplementation with lutein and zeaxanthin may boost macular pigment optical density (MPOD) and retinal sensitivity in people with early age-related macular degeneration (AMD), says a new study.
A combination of lutein, zeaxanthin and omega-3 long-chain polyunsaturated fatty acids may boost the pigment in the retina and help people with age-related macular degeneration (AMD), says new data from Germany.

Claims that meso-zeaxanthin is not required for eye health formulations in addition to the established ingredients, lutein and zeaxanthin, are "misleading" and "erroneous", leading eye-health researchers tell NutraIngredients.
Supplementation with the carotenoids lutein and zeaxanthin could
boost retinal health in the eyes, and have benefits for people with
seemingly healthy eyes, says a new study.
Supplementation with meso-zeaxanthin, an unusual and consequently
rare isomer of zeaxanthin, may offer protection against age-related
macular degeneration.
Lutein supplements, shown previously to fortify the macular layer
in the eye and thought to protect against age-related blindness,
also appear to increase macular pigment in people at earlier stages
of age-related macular degeneration...
A study by researchers in Manchester, England, suggests that
Cognis' Xangold natural lutein ester supplements may promote eye
health in the elderly. If the evidence is confirmed, dietary
supplements and a higher intake of fruits...
