Get natural support for your vision and eye health. Natural Factors' Lutein delivers this essential carotenoid to the retina and macula, the central area of the retina responsible for vision. We've blended lutein with zeaxanthin to provide nutritional support to the eyes and skin and defend against sunlight-induced free radical damage. Our formula uses LuteinRich, which is naturally sourced from marigold petals and is non-irradiated and non-GMO.**These statements have not been evaluated by the FDA.
