Lutein, also known as xanthophyll, is a yellow carotenoid found is several vegetables, fruits, corn, flowers, and in egg yolks. The best source of lutein is the marigold flower (Tagetes erecta). Carotenoids are a group of natural fat-soluble pigments that play a significant role in the human body. They are well-known for their biological and chemical properties since they act as natural antioxidants aiding in protecting cells and tissues from the damaging effects of singlet oxygen and other free radicals.
However, among the over 600 compounds of known carotenoid pigments, less than 20 are found in the human body. In addition to other essential antioxidants, the human body does not synthesise lutein nor any other carotenoid. Therefore, all carotenoids found in the body are derived from dietary supplements or foods that people eat. Lutein is one of the largest groups of carotenoids and is a highly effective anti-oxidant that has enhanced stability and is, therefore, useful in multiple applications.
Although the best option would be to obtain lutein naturally, Lutein 20% helps realise the anti-oxidant’s full potential concerning disease prevention, chemical, and biological benefits. Other than its anti-oxidant properties, lutein can be converted to vitamin A in the body, which is an essential micronutrient that promotes normal vision. In the macula, lutein together with zeaxanthin filters out potentially harmful UV and blue light, protecting the sensitive optic nerve cells from damage. Recent studies demonstrated that lutein is also likely to protect against skin cancer, prostate and breast cancer, cardiovascular diseases, and certain diseases of the eye such as glaucoma and cataracts. In addition, people with existing eye problems or damage can decelerate or even stop the condition from progressing by adding plenty of lutein to their diet.
