Age related vision loss or age related macular degeneration (AMD) is caused by steady damage of the retina. Lutein probably acts by preventing oxidative damage of the retina cells. Lutein is concentrated in the central part of the retina, called the macula. In the macula are yellow pigments (macular pigments composed of zeaxanthin and lutein) which protect the retina from damage of the photo-oxidative affect of blue light. Lutein can reduce the risk for artery diseases.In addition, Lutein can also reduce the risk of skin cancer and sunburn. Under influence of sunlight, free radicals are formed inside the skin. These free radicals can damage the DNA of cells. Lutein can protect against the damaging effects of UV-B radiation.【CHEMICAL ANALYSIS】 ITEMSRESULTSAssay BY UVLutein content >20%ColorEven YellowTasteCharacteristicOdorCharacteristicParticle size95% through 80 meshHeavy Metals≤10PPMMoisture≤8%Ash≤3%SolventHexane 【PACKAGE】：Packed in paper-drums and two plastic-bags inside.N.W.:25kgs .【STORAGE】：Keep in cool, dry and dark place, avoid high temperature.【SHELF LIFE】：24 months
