What does Ocolut contain? Lutein 6 mg in 1 capsule What is it? Lutein is a member of the carotenoid family. It is fat-soluble yellowish pigment found in some plants, algae and photosynthetic bacteria. It serves as accessory light-gathering pigment and protects these organisms against the toxic effects of ultra-violet radiation and oxygen. Lutein is found in the macula of the human retina, as well as the human crystalline lens and together with zeaxanthin are called macular pigments. It is thought to play a role in protection against age-related macular degeneration and age-related cataract formation. How does Lutein work? Lutein exerts its ophthalmo-protective effects in 2 ways. First it filters out and neutralizes phototoxic ultra-violet radiation and second it has antioxidant activity. After oral administration Lutein is absorbed in the intestine. Lutein may be more efficiently absorbed when administered with high-fat meals, than with low-fat meals. Lutein binds to specific retinal protein and distributed throughout the retina and mainly accumulated in the macula.
