Product Name: Zeaxanthin
Zeaxanthin source:Lutein and Zeaxanthin are found in the macula of the human retina, as well as the human crystalline lens. They are thought to play a role in protection against age-related macular degeneration (ARMD) and age-related cataract formation. They may also be protective against some forms of cancer. These two carotenoids are sometimes referred to as macular yellow, retinal carotenoids or macular pigment.
Zeaxanthin introduction: 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.
