Lutein, zeaxanthin, and astaxanthin are part of the carotenoid family known as xanthophyll carotenoids. Lutein and zeaxanthin are exclusively found in the macular part of the eye retina which protects the photoreceptor cells by filtering out the high-energy blue light. Both antioxidants also influence visual processing, support brain function, and enhance memory and learning. Meanwhile, astaxanthin, nature’s most powerful antioxidant helps to combat inflammation and oxidative stress and increases the eyes’ capillary blood flow.
