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.

Lutein and zeaxanthin are the only carotenoids capable of filtering the harmful blue light than can damage cells in the eye, the rods and the cones.


Increased intakes of lutein may not only have a direct beneficial role in the macula of the eye, but may also affect inflammation, says a new study.

Results from a one year study indicated that 10 mg per day of lutein indicated that supplementation with the carotenoid significantly reduced levels of sC5b-9, a marker of systemic inflammation, compared to placebo.


The naturally-occurring carotenoids lutein and zeaxanthin can enhance visual performance among young and healthy consumers, according to new research sponsored by two nutritional manufacturers.
