Lutein, also known as carotenoid, carotenol, phytolutein, riboflavin, marigold and lutein, etc. Lutein coexists with zeaxanthin in nature. It is the main component of plant pigments such as corn, vegetables, fruits, flowers, etc. It is contained in the chloroplast of leaves and can transfer the absorbed light energy to chlorophyll a. Light oxidation and light damage have a protective effect. It is also the main pigment that constitutes the macular area of the retina of the human eye.
Lutein is a nutrient that humans can absorb when eating fruits and vegetables daily, but the absorption and utilization rate is generally low. If you lack lutein, you can take supplements. If you have a poor digestive system, you can use a sublingual spray to supplement lutein. Lutein has been added as a dietary supplement as early as 1996. In addition, excessive intake of lutein will cause excess burden on the liver, and the recommended daily dosage is about 12 mg.
