What is Doctor's Best Lutein with FloraGLO?
Doctor's Best Lutein with FloraGLO with Zeaxanthin maintains healthy visual function and supports macular pigment density. The lutein from FloraGLO supports skin health and helps prevent aging of the skin. It supplies high quality FloraGLO Lutein, a highly bioavailable, natural source of lutein. Lutein and zeaxanthin are two of the major carotenoids found in humans, and are highly concentrated in the retina of the human eye. Lutein and zeaxanthin are also potent free radical neutralizers that likely contribute to the body's spectrum of antioxidant defenses.

How does it work?
Most of the beneficial effects of xanthophylls, which are photochemical transformations of lutein, are ascribed to their ability to quench reactive oxygen species and scavenge other free radical substances that are either taken in from the environment or generated internally by natural metabolic processes. In vitro evidence for the free radical scavenging activity of lutein is found in studies of its effects on human lens epithelial cells. In one such study, cell cultures were exposed to ultraviolet (UV) light after pretreatment with lutein or alpha-tocopherol. Both nutrients were found to reduce UV-induced damage to lens epithelial cells. However, lutein was shown to have significantly higher photoprotective activity than alpha-tocopherol, demonstrating its potential as a high-powered antioxidant. Lutein has also been found to be an effective filter of "blue light," another daily source of oxidative stress on the polyunsaturated fatty acid-enriched photoreceptors of our eyes.

Why should I take Doctor's Best Lutein with FloraGLO?
Lutein and Zeaxanthin are yellow pigments in a class of carotenoids called xanthophylls. Since the human body does not synthesize them, we rely on dietary sources for these carotenoids. The average American consumes only 2mg of lutein & zeaxanthin per day. The best sources for these important nutrients are dark leafy-greens like spinach, collards, and kale, in addition to certain yellow-orange fruits & vegetables. Lutein, zeaxanthin, and meso-zeaxanthin are referred to as "the macular pigments," as they are the only carotenoids found in the lens and macular region of the retina of the human eye. Over 20 studies in humans using FloraGLO Lutein, established a body of literature published in peer-reviewed journals or presented as abstracts at scientific conferences that confirms the efficacy and safety of this particular ingredient.
