MacuGuard® Ocular Support with Saffron provides lutein, trans-zeaxanthin, and meso-zeaxanthin, three important nutrients that protect the delicate photoreceptor cells in the retina's macula from light damage. This innovative formula also contains C3G (cyanidin-3-glucoside), a cutting-edge berry flavonoid compound that helps stimulate regeneration of rhodopsin, a compound in the eyes that absorbs light in the retina to help support night vision.
