As a well-known carotenoid, zeaxanthin can be found in the macula, usually accompanied by lutein. In fact, lutein is believed to be less effective without zeaxanthin. Some daily foods contain plentiful of these two nutrients.
Zeaxanthin and lutein can fight off the free radicals caused by harmful rays and medications. The common eye disease age-related macular degeneration is exactly caused by these harmful radicals.
The two nutrients always appear together because they are cooperative. Zeaxanthin can repair and protect the cones in the macula and lutein ensures the well being of the rods which constitute the periphery of the retina. In addition, rods and cones work together and ensure good eyesight. In this case, eyesight may deteriorate if one of the two nutrients goes bad.
Zeaxanthin can be easily found in corn, pepper, saffron as well as other plants. And saffron maintains its characteristic taste and aroma through zeaxanthin. In addition, green leafy vegetables also contain plentiful of zeaxanthin and lutein, so that ordinary people are highly encouraged to eat a diet rich in green vegetables.
Studies show that natural sources of zeaxanthin are always better than those supplement pills. But zeaxanthin and lutein from these natural sources need a long period to build up vital reserves. In an emergency situation, supplements containing zeaxanthin and lutein can offer immediate help. Whats more, some people do not eat healthy foods. For those individuals, supplement pills are especially needed.
Most nutrient experts set the dosage of each zeaxanthin and lutein at about 24 mg each day. With proper dosage, central vision and color perception can be improved.
There are still other nutrients that are indicated to improve eye health, such as vitamin B12 and B2, I-carnosine, anthocyanins, beta-carotene and glucosamine.
