Lutein, also known as phytolutein, is widely found in vegetables, fruits, flowers and other plants. Our free lutein is extracted from marigold flower, natural and pure. It is a carotenoid and the main pigment found in the macular area of the human eye. Lutein is non-toxic and harmless with its special physiological effects, which is in line with the development direction of "natural", "nutritional" and "multifunctional" food additives. It can be combined with common food additives such as vitamins and lysine, adding directly to food. Lutein is an important natural pigment and natural health product and it is a green healthy food material.
Marigold Extract Zeaxanthin
Lutein and zeaxanthin are carotenoids that filter harmful high-energy blue wavelengths of light and act as antioxidants in the eye, helping protect and maintain healthy cells. Of the 600 carotenoids found in nature, only two are deposited in high quantities in the retina (macula) of the eye: lutein and zeaxanthin. The quantity of lutein and zeaxanthin in the macular region of the retina can be measured as macular pigment optical density (MPOD). Recently, MPOD has become a useful biomarker for not only predicting disease but also visual function.

Lutein, Zeaxanthin and Cataracts
The primary function of the crystalline lens (or natural lens in the eye) is to collect and focus light on the retina. To properly provide this function throughout life, the lens must remain clear. Oxidation of the lens is a major cause of cataracts, which cloud the lens. As antioxidant nutrients neutralize free radicals (unstable molecules) associated with oxidative stress and retinal damage, lutein and zeaxanthin likely play a role in cataract prevention. In fact, a recent study demonstrated that higher dietary intakes of lutein and zeaxanthin and vitamin E was associated with a significantly decreased risk of cataract formation.
Lutein, Zeaxanthin and Age-Related Macular Degeneration
Much evidence supports the role of lutein and zeaxanthin in reducing the risk of AMD. In fact, The National Eye Institute presently is conducting a second large human clinical trial, Age-Related Eye Disease Study (AREDS2), to confirm whether supplements containing 10 mg a day of lutein and 2 mg of zeaxanthin per day affect the risk of developing AMD. Beyond reducing the risk of developing eye disease, separate studies have shown that lutein and zeaxanthin improve visual performance in AMD patients, cataract patients and individuals with good health.
