NOW® Clinical Strength Ocu Support has been formulated to provide comprehensive nutritional protection for the eyes. Each serving contains 10 mg of available Lutein, a critical pigment of the macula, lens, and other ocular tissues. Lutein is a powerful antioxidant related to beta-carotene that defends the eye from the ravages of sunlight. NOW has also included Green Tea Extract, Alpha-Lipoic Acid, Grape Seed Extract, and other synergists in this formula to maximize its antioxidant potential.*
Clinical Strength Ocu Support FAQ's
What makes Clinical Strength Ocu Support an effective supplement?
Although there are many biologically active ingredients in the Clinical Strength Ocu Support formula, the two ingredients with the most supporting research in Clinical Strength Ocu Support are Lutein and Zeaxanthin.
According to a study published in the April 2004 edition of Optometry: The Journal of the American Optometric Association, the lutein antioxidant supplementation trial (LAST) concluded that visual function of study participants with symptoms of age-related macular degeneration (ARMD) improved with the intake of lutein alone or lutein together with other nutrients such as antioxidants, vitamins, and minerals.
Lutein and Zeaxanthin are fat soluble, yellow-colored carotenoids found naturally in spinach and other green leafy vegetables, egg yolks, yellow corn, yellow squash, peaches and marigolds. Although these carotenoids are found in fatty tissues throughout the body, by far the highest concentration is found in the macula and retina of the eye. These fat-soluble antioxidants have been found to stop free radical reactions, specifically the photo-reactive oxygen species that are particularly damaging to eye and skin tissues. Think of internal ‘blue-blocker’ sunglasses!
What role do some of the other key ingredients play?
Beta-Carotene is another antioxidant carotenoid found naturally in dark green and orange-yellow vegetables and fruit. Unlike Lutein, Beta-carotene can be converted to Vitamin A as needed by the body. Vitamin A is necessary for proper eye function and low antioxidant levels may contribute to cataract formation.
Bilberry, Green Tea, Ginkgo Biloba and Grapeseed extracts contain compounds called Polyphenols and Anthocyanidins. These antioxidant compounds protect blood vessels that supply needed blood flow to the eyes and peripheral tissues.
Rutin and the other Bioflavonoids stabilize the collagen matrix and maintain the integrity of the vital blood vessels that carry oxygen and nutrients to the eyes.
Vitamins C and E are antioxidants that inhibit free radical damage and are used by the body to prevent some of the degenerative patterns related to the aging process. Vitamin C may protect the eye from UV rays that can damage the lens. This kind of oxidative damage may contribute to the formation of cataracts.
Taurine is a sulfur-containing amino acid that is the most abundant amino acid in the retina of the eye and plays a role in healthy vision.
Selenium and Zinc are minerals that help the body to produce the important antioxidants Glutathione and SOD, which protect eye tissues from oxidative damage.
