Most people would consider vision to be the most precious of their senses, so it makes sense to protect it. Certain nutrients prevent damage to the eyes and improve vision. A few of these nutrients can be obtained sufficiently in food; most only by supplementation.
• Beta-carotene occurs as retinal in the photoreceptor cells; protects the cornea; improves night vision
• Lutein, astaxanthin & zeaxanthin are fat-soluble antioxidants concentrated in the lens and macula; protect delicate photoreceptor cells from UV rays and free radicals; prevent cataracts and Age-related Macular Degeneration (AMD)
• Astaxanthin is the most potent antioxidant for protecting the eyes; protects DHA oxidation in the eye; inhibits inflammation; reduces eyestrain fatigue from computer use; protects or treats AMD, Cataracts, Diplopia (double vision), Diabetic Retinopathy, and depth perception problems
• Anthocyanins, water-soluble antioxidants found in dark berry pigments (bilberries, blackberries, blueberries), protect the eyes and improve vision
• Cyanidin-3-glucoside (C3G) is the most important anthocyanin for the eyes; improves night vision, reduces eye fatigue from computers
• Vitamin E: gamma tocopherol (GT) and alpha tocopherol (AT) work more effectively together, with GT the most important; protect eyes from free radicals and inflammation; help prevent cataracts and AMD
• Benfotiamine is a special form of Thiamine (B1) for the eyes; helps prevent glaucoma, cataracts, AMD, Diabetic Retinopathy and eye inflammation
• Zinc and Selenium are mineral antioxidants; methionine form best for safety and bioavailability for the eyes; selenium reduces risk of AMD, cataracts and glaucoma; zinc is concentrated in choroid layer of the retina which provides oxygen and nutrients to the photoreceptor cells
• L-Taurine is a sulfur containing amino acid essential for healthy eyes; improves Diabetic Retinopathy; helps prevent AMD
