Optimize your eyes' protection against free radicals with our Swanson Ultra Ultimate Ocular Antioxidant formula. We combined nature's most effective antioxidant carotenoids for protecting eye tissues in one powerful formula to help maintain healthy eyesight at any age. Lutein and zeaxanthin are the two most prevalent carotenoids in the macula and retina of the eye, where they neutralize free radicals generated by environmental pollutants and protect against photo-oxidative damage. The effects of these antioxidants are enhanced even further by astaxanthin, a carotenoid cousin of zeaxanthin with unique photo-protective properties of its own. Unparalleled in quality and potency, our Ultimate Ocular Antioxidant features Non-GMO Project Verified Lutemax(R) 2020, a carotenoid complex extracted from marigold flowers. This high- potency complex delivers an impressive 20 mg of lutein and 4 mg of zeaxanthin isomers per softgel. Each softgel also includes 4 mg of algal-source astaxanthin in a safflower oil base that ensures optimal absorption and assimilation of these powerful fat-soluble carotenoids. It's nature's ultimate antioxidant all-star team for everyday vision protection.
