Introduction:
Lutein, also known as "phytolutein", co-exists with zeaxanthin in nature. Human eyes contain high amounts of lutein and zeaxanthin, but these two elements cannot be manufactured by the human body and must be supplemented by foods containing lutein and zeaxanthin. Without these two elements, the eyes will be blind. Lutein and other carotenoids are thought to have antioxidant properties. Antioxidants protect cells from damage caused by free radicals. Lutein fights free radicals like vitamin E, a powerful antioxidant. Lutein is concentrated in the retina and lens and protects vision by neutralizing free radicals and increasing pigment density.
Benefit:
1.These carotenoid compounds extracted and refined from marigold flowers are not only beneficial to prevent eye muscle degeneration, effectively improve vision, but also prevent cardiovascular atherosclerosis, coronary heart disease, tumors and other diseases.
2.Studies have shown that supplementation with these carotenoids can restore macular pigment density that declines with age. Lutein has superior tinting strength.
3.They are widely used in food, cosmetics, feed additives and pharmaceuticals.
