Eye protection from lutein and zeaxanthin

Eye protection from lutein and zeaxanthin

Lutein and zeaxanthin as powerful antioxidants are becoming increasingly important, suggested by some recent studies. These antioxidants can effectively fight against free radicals, preventing them from roaming about the eyes. Another function of these two antioxidant substances is to prevent oxidative stress from the blue light rays of the sun. In fact, lutein and zeaxanthin give rise to the color in many fruits and vegetables as well as some plants. Belonging to the carotenoid family, lutein and zeaxanthin have been considered as the strongest protection against macular degeneration and cataracts.

Oxidation can easily damage the retina if no prevention is taken. This damage is much likely to lead to age-related eye diseases such as macular degeneration. Zeaxanthin and lutein which are naturally found in the retina, can offer appropriate protection for the retina, especially the macula. The most convenient way to get enough amounts of these nutrients is to take supplements. Zeaxanthin and lutein supplements sold on the market have been carefully developed and researched by professional scientists. Customers can even ask the salesman about the details of supplement production process.

However, purchasing nutritional supplements also requires some precautions. Customers should learn to know how these supplements were made as well as their manufacturers. The reason lies in that there are many supplement products that do not deliver on their promises, although good quality pills are also available. Some manufacturers even have some tricks to keep customers in the dark. For instance, they may suppose most customers will ignore the difference between measurements such as mcg and mg. In fact, mg is 10 times the amount of mcg.

In this case, customers should always check the amount of zeaxanthin or lutein in supplements, which is usually marked on the bottle or described in the information they provide. Low amounts of these nutrients are useless. Furthermore, people are highly encouraged to take multi-nutritional supplements, which are believed to be more effective in preventing age-related eye diseases than supplements containing only lutein and zeaxanthin.
