Lutein is widely found in nature, especially in green leafy vegetables such as spinach, cabbage, kale, broccoli, and Swiss chard. Lutein can also be found in marigolds, egg yolks, and certain microorganisms.
Lutein has powerful antioxidant properties that can neutralize free radicals in the body, reduce damage to cells caused by oxidative stress, and thus maintain the health of cells and tissues, which may help reduce the risk of chronic diseases such as cancer, cardiovascular disease, and age-related eye diseases.
Lutein plays an important role in the retina, absorbing blue light and helping to protect the eyes from optical damage. It helps prevent retinal degenerative diseases such as macular degeneration, thereby maintaining clear and sharp vision.
Lutein may help reduce high blood pressure and improve cardiovascular health. It can promote blood vessel elasticity, lower cholesterol levels, and reduce the risk of arteriosclerosis.
It is believed to have anti-inflammatory properties that help reduce chronic inflammation and related health problems.
