What are lutein and zeaxanthin?
Lutein and zeaxanthin are the only carotenoids known to selectively accumulate in the eye tissues. They are absorbed from the diet into circulation and deposited in the lens and macular regions of the eye. Because the eyes are subjected to such a high degree of oxidizing radiation each day, a generous dietary intake of these carotenoids is essential to provide optimal protection to delicate eye tissues. Research studies have shown that in the lens, lutein and zeaxanthin may provide protection against cataract formation. Similarly, other studies have shown a strong correlation between high dietary intakes of lutein and zeaxanthin with protection from age-related macular degeneration (AMD).
