Zeaxanthin, Lutein
Description of zeaxanthin
Basic information
Lutein and zeaxanthin are both carotenoids, which are mainly synthesized by plants and have a high content in marigold, corn and other plants, and also have a certain content in animal tissues. Lutein and zeaxanthin are isomers of each other and are important components of human retina and lens. Among them, zeaxanthin and lutein mainly exist in the macular region of the retina.
Zeaxanthin itself does not have the activity of vitamin A, but it and its isomer lutein play an important role in the prevention of age-related macular degeneration (AMD). Zeaxanthin is widely found in human body and has high concentration in eye, pancreas, liver, spleen, kidney, ovary and other tissues and organs, which plays an important role in human health. There are many carotenoids in human blood, but only zeaxanthin and xanthin are concentrated in the central position of the retina inside the human eye, which is clinically known as the macula and is the most effective component to prevent retinal damage caused by light exposure. Lutein is mainly deposited in the intermediate fovea of the retina, while zeaxanthin is dispersed in the retina. The entry of the two substances into the retina is mediated by specific lutein-binding proteins. Zeaxanthin and lutein protect retinal nerves from photooxidative damage mainly by filtering blue light and strong antioxidant properties, delaying the development of a series of retinal and lens lesions, and ultimately preventing or delaying the occurrence of age-related eye diseases and macular pigment abnormalities. Zeaxanthin cannot be synthesized by the body itself and must be consumed through diet
Health function
Oxidative damage of cells is caused by the imbalance of antioxidant protection and free radical metabolism in the body, which can lead to a variety of diseases. Zeaxanthin molecule has 11 conjugated double bonds, plus the hydroxyl group on its terminal structure, with strong antioxidant capacity, can play an antioxidant role in the organism by reducing the reactivity of active substances (such as free radicals, singlet oxygen), protect the body’s tissues and cells, and reduce the risk of certain diseases. Epidemiological investigation shows that zeaxanthin has unique physiological functions of antioxidant, prevention of age-related macular degeneration, cataract, reducing the incidence of cardiovascular disease and reducing the occurrence of cancer.
Zeaxanthin itself also has high nutritional value, which has special effects on promoting human growth and development, protecting epithelial cells, improving disease resistance and prolonging life. In recent years, due to the photoprotective ability of zeaxanthin, it can also be used as a photosensitive cell protector. In addition, zeaxanthin also has the effect of protecting skin, delaying aging and reducing lipofuscin formation, which makes zeaxanthin emerge in the field of cosmetics.
Description of lutein
Basic information
Lutein, also known as “eye gold”, is the most important nutrient in the human retina. It is found in the macula (the center of vision) of the retina of the eye and in the lens, especially in the macula which contains a high concentration of lutein. Lutein is an important antioxidant, a member of the carotenoid family, also known as “plant lutein”. It co-exists in nature with corn lutein. Scientific studies have shown that lutein is the only carotenoid found in the retina and lens of the eye, and this element is not manufactured by the body itself, and must be supplemented by external intake. In the absence of this element, the eye will go blind. The ultraviolet and blue light from sunlight entering the eyes can produce a large number of free radicals, which can lead to cataracts, macular degeneration, and even cancer. Lutein can filter blue light, decompose strong light and ultraviolet damage to the human eye, so as to avoid blue light damage to the eyes, to prevent vision degradation and blindness caused by lutein loss, so lutein is also known as the eye protection god.
