OcuGuard Plus with Lutein, Zeaxanthin and Vitamin D3 (cholecalciferol) is an advanced vitamin and antioxidant nutritional supplement specifically formulated to support healthy vision clarity. Each easy-to-swallow capsule provides a special combination of micronutrients the eyes may require, including Lutein, Zeaxanthin and beta-carotene, which are potent antioxidant carotenoids. Lutein is the most abundant carotenoid in fruits and vegetables, and is found to be highly concentrated in the macula of the eye. Combining Lutein and Zeaxanthin carotenoids with Vitamin D3 provides dual-action macular support for healthy eye and vision clarity. Other nutrients included in this synergistic formula are zinc from zinc picolinate (a chelated from a zinc that is easy for the body to absorb and use), natural Vitamin E, Vitamin C, selenium, and much more.
