1. Function and Application
Zeaxanthin is less common in the human diet-coming from certain orange and yellow fruits and vegetables Meco- zeaxanthin is not found in the normal human diet, and is thought to originate from Lutein. The high concentrations and specific uptake of the macular carotenoids is mediated by specific binding proteins that draw them into the tissue and stabilize them.
Studies have shown that eating lutein-and zeaxanthin-rich foods or taking supplements of these carotenoids canrestore macular pigment density, which declines with age .In fact, one such study of advanced macular degeneration patients who were taking high-dose lutein supplements(4mg or more per day) experienced normal levels after a few months. A Harvard-led study demonstrated that eating lutein-rich foods five days per week meant subjects were eight times less likely to develop macular degeneration compared to those who consumed the same foods just once per month.
