The PIXEL Complex contains four xanthophyll carotenoids: lutein, zeaxanthin, meso-zeaxanthin, and astaxanthin. Lutein, zeaxanthin, and meso-zeaxanthin (also known as “macular pigments”) specifically accumulate in our macula where they provide antioxidant protection and function to filter blue light to support visual performance. As we age, however, levels of these three pigments decline. Supplementation with a specific combination of these three pigments has been clinically proven to increase macular pigment density and increase contrast sensitivity and vision in glare and low-light conditions. Astaxanthin in the PIXEL Complex is also a potent antioxidant and is clinically proven to improve blood flow to the retina to support the delivery of nutrients and oxygen and support eyes during extended screen use.
