1. Improve eyesight: When the retina is exposed to light and oxygen, it will be damaged by free radicals. Lutein is a high-concentration antioxidant, which can help filter out blue light, reduce color difference and make vision more accurate.

2. Protect the retina: The retina is rich in DHA unsaturated fatty acids, and lutein is a good antioxidant to prevent the retina from being damaged by oxidation when absorbing light.

3. Reduce cataracts: Lutein is the only carotenoid that can exist in the lens, and the damage of free radicals to the protein of the eye lens is the main cause of cataracts.

4. Treatment of retinitis pigmentosa: When retinitis pigmentosa occurs, rod-shaped cells and cone-shaped cells on the retina will undergo degenerative changes. Lutein supplementation is helpful for retinitis pigmentosa.

5. Prevention of breast cancer: Lutein can be used as an anti-reproductive agent of breast cancer cells to prevent the spread of breast cancer.

6. Reduce heart disease: the ability to kill hydrogen and oxygen free radicals is 1000 times greater than that of vitamin E, preventing cell damage.

7. Relieve asthenopia: In addition to the above, lutein ester can also relieve asthenopia quickly and improve symptoms such as dry eyes, blurred vision, eye swelling, photophobia and eye pain.

Second, it is suitable for people with lutein esters.

First, patients with low vision Modern people do not develop good habits due to the influence of life and work and daily life. Most people are in a state of low vision. When the human body lacks lutein, it is prone to macular degeneration and poor vision, and lutein has an extremely important protective effect on macular in the retina. Appropriate supplementation of lutein is helpful to protect vision and inhibit the deterioration of vision.

Second, the study of people who need to delay aging found that with the increase of age, reactive oxygen free radicals in the human body can react with DNA, protein and lipids, which will weaken the physiological function of the human body, and then appear pigmentation, dry skin and other phenomena. Lutein has strong antioxidant properties, which can inhibit the activity of oxygen free radicals and prevent the damage of active oxygen free radicals to normal cells, thus achieving the purpose of delaying aging.

Third, people with low immunity With the increase of life and work pressure, the immune ability of the human body will gradually decline, which will lead to the phenomenon of easy catching a cold and forgetfulness. Lutein can destroy living singlet oxygen by physical or chemical quenching, protect the body from damage, and then enhance the immune ability of the body. Fourth, patients with chronic diseases when the lutein content in human blood is low, it is easy to cause arterial wall thickening, thus a series of chronic diseases (such as hypertension, cardiovascular and cerebrovascular diseases, etc.) appear.
