A member of the carotenoid family, Lutein is a nutrient with potent antioxidant abilities recognised as being important for human health to such a degree that a deficiency in these vital nutrients is thought to be the main cause of age related macular degeneration. Studies demonstrate Luteins ability to thicken the pigment layer in the macula, protecting against degeneration, and neutralize harmful chemical reactions involved in light detection. Up to 10mg of Lutein per day has been clinically proven to significantly reduce the risk of or indeed the progression of age related macular degeneration and cataracts.
