Lutein, Zeaxanthin and Age-Related Macular Degeneration

[MineralMan]

In recent years, the carotenoids, lutein and zeaxanthin have become better known than in times past. There is some evidence that suggests that the lack of adequate amounts of these two nutrients may play a role in age-related macular degeneration, a major cause of blindness in the elderly. Studies are still ongoing to determine the exact role these nutrients have in preventing that disease, which is one of most common reasons for vision deterioration as we age.

Since both are natural parts of most people's diets, and are found in everything from egg yolks, corn, and many other vegetables, people who eat a balanced, healthy diet probably get all they need of these minor nutrients. However, not everyone eats a well-balanced diet that supplies adequate amounts. So, increasingly, ophthalmologists and other physicians are suggesting supplementing dietary intake of these nutrients to some of their patients, particularly those who show signs of early macular degeneration. To that end, the two nutrients have been added to many multi-vitamin supplements, and are available in other forms as well on the market, both at local drugstores and at vendors of nutrient supplements.

Studies are still going on, and optimal levels have not been set for these nutrients, but many physicians and ophthalmologists do make specific recommendations, often suggesting a product from Bausch and Lomb, a major manufacturer of optical products, including contact lenses. Similar amounts are available in a wide variety of supplement products, so consumers have a wide range of choices, if such supplementation is recommended by medical professionals.

To learn more about these two nutrients, you can visit the Wikipedia pages below, which also contain many links to additional sources. If you think such supplements could benefit you or they are recommended by a health care professional for you, the available products that contain them are many, and are available everywhere, including your local supermarket. In the articles, you'll also find which normal foods you may include in your diet are rich in these nutrients. The more you know, the less likely you are to be ripped off by marketing claims for expensive supplements that are identical with less expensive options. Get the facts from objective sources, then make your own choices, based on information rather than marketing claims.
