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 eye and protects
against the development of cataracts by protecting against light-generated
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
