Lutein helps to protect against the development of Age-Related
Macular Degeneration (ARMD) [3 mg or more per day of lutein lowers the risk of developing ARMD
Lutein concentrates in the Lens of the Eyes. Lutein protects
against the development of Cataracts by protecting the Cells of
the Eyes from light-generated Free Radicals)
Lutein concentrates in and improves the health of the Macula
(yellow spot on the back) of the Retina of the Eyes (it is
particularly concentrated in the Rods) [30 mg of Lutein per day
caused the Macula to become denser and to gain pigment. After 140
days of Lutein supplementation, Macula pigmentation increased by
an average of 30%. Improvements in Macula health/function
continued for six weeks after Lutein supplementation was
