In the past, I have written about reports on the benefits of zeaxanthin and lutein supplements on eye health such as reducing cataracts and age-related macular degeneration risks. But to date, it has remained unclear how these compounds confer their protective benefits.
A new study published in the Journal of Lipid Research, however, provides clues as to how the compounds move from the blood stream to the eye. Apparently, a protein called SR-B1, or scavenger receptor class B, type 1, is responsible for transporting nutrients to the eye.
These study provides supporting evidence on the potential of zeaxanthin and lutein in preventing …read more

According to a prospective study published this month in Archives of Ophthalmology, higher dietary intakes of lutein, zeaxanthin and vitamin E from food and supplements were found to be associated with significantly decreased risks of cataract among women. A cataract is an age-related condition characterized by clouding of the lens in the eye, thus affecting vision.
According to this related article in WebMD:
Foods rich in lutein and zeaxanthin include leafy green vegetables (such as spinach, kale, turnip greens, collards, and mustard greens), squash, green peas, broccoli, pumpkin, and corn.
Foods rich in vitamin E include vegetable oils, almonds, sunflower seeds, leafy green …read more

A recent study indicates that Cognis’ Xangold lutein and zeaxanthin supplement (12 mg lutein for six months) is effective at boosting eye health among those with early-stage age-related macular degeneration (AMD). AMD is the number one cause of severe vision loss and legal blindness in adults over 60 in the U.S.
“A significant augmentation of macular pigment density was found in a majority of study subjects, including those afflicted with AMD. The importance of these findings rests on the fact that the beneficial effects of these antioxidants can also be extended to subjects with established disease.”
It seems that supplemental lutein and/or …read more
