Our Essentials™ formula is a high-potency, once-daily capsule with lutein (LOO-teen), zeaxanthin (Zea-Zanthin) and selenium designed to be taken with multivitamins and any AREDS formula as an extra measure to fight Macular Degeneration. Lutein is a nutrient found in vegetables and fruits, particularly leafy greens like spinach and kale. Lutein acts as an antioxidant, protecting cells against the damage caused by free-radicals, highly unstable forms of oxygen. What makes lutein unique from other antioxidants such as vitamin C or beta-carotene is the fact that it is highly concentrated in the macula, the part of the eye that’s responsible for central vision. While lutein is found naturally in the body, it cannot be made by the body and must be obtained from food or dietary supplements. Zeaxanthin also is not made by the body and high levels can only be obtained from supplements. Like lutein, zeaxanthin is found in the macula, however it is much more concentrated in the center part of the macula compared to lutein. Our Essentials™ contains OPTISHARP™ brand zeaxanthin from DSM (formerly Roche Vitamins).
