Lutein is a yellow member of the carotenoid family.  It is one of the major carotenoids found in human blood, with a high tissue concentration in the retina (and macula) of the human eye.  Lutein functions as a potent free radical scavenger in a number of tissues, including the eyes, skin, heart and lungs. * Zeaxanthin is the second major carotenoid found in the retina. Both lutein and zeaxanthin work synergistically to promote eye health.*  

FloraGLO Lutein is a source of purified free lutein, identical to that found in green leafy vegetables.  FloraGLO Lutein is extracted from marigold flowers, the most abundant source of lutein in nature. This patented process (US patents 5,382,714 and 5,648,564) ensures a standardized, potent and pure end product every time. Much of the published research on lutein has used FloraGLO Lutein, which has created an extensive body of literature supporting the efficacy and safety of this product in human and animal models. Additionally, in vitro studies have pointed to multiple mechanisms by which FloraGLO lutein confers benefit to eye, skin and general health. FloraGLO has also been used in more clinical trials than any other source of lutein, ensuring that the benefits found in these trials can be attributed specifically to FloraGLO Lutein.
