The importance of lutein for the eyes is similar to that of CoEnzyme Q10 for the skin. Lutein is a natural nutrient in the retina, but aging will cause it to thin. What's more disappointing, the eyes can not reproduce lutein by itself. But lutein as a powerful antioxidant is critical in preserving eye health. Antioxidants can fight against free radicals caused by UV rays and blue light. The commonest condition caused by lutein deficiency is probably age related macular degeneration.
Taking proper amount of lutein every day is essential to maintain healthy eyes. Age related macular degeneration can lead to blindness in an extreme case. Of course, no one wants to suffer from this condition because blindness will make an independent life impossible. In moderate cases, lutein intake is also needed to maintain healthy eye cells, especially for old individuals between 60 and 85. And the proper dosage of lutein everyday is between 6mg and 10mg.
In general, the public can get lutein nutrient from two main sources. The first one is eating diet. Platefuls of vegetables everyday are useful for people to get plenty of lutein. In fact, lutein is a special pigment that can be found in many green leafy vegetables and fruits. Good sources of lutein include collard greens, Swiss chard, broccoli, cabbage, corn, egg yolks and so forth. These natural substances are absolutely best sources of lutein nutrient. But the amount of lutein in these foods is usually inadequate.
Nutritional supplements coming in different brands and formulas effectively bridge this gap. They are good alternatives to natural foods contained in diet. Lutein is a must in these supplements, which has been explained before. But this nutrient is not enough. Supplement formulas usually contain many more substances such as vitamins and minerals. In addition, zeaxanthin, bilberry as well as other protective nutrients should also be contained. A supplement formula that contains multiple nutrients working in synergy is the best.
