Lutein is an important antioxidant, a member of the carotenoid family (a group of naturally fat-soluble pigments found in plants), also known as "phytolutein", which occurs in nature alongside zeaxanthin.

Lutein is a kind of natural substance widely existing in vegetables, flowers, fruits and other plants, belonging to the "carrot-like" group of substances, known in nature there are more than 600 kinds of carotene, of which only about 20 exist in human blood and tissue. Carotenoids found in humans mainly include alpha-carotene, beta-carotene, cryptoflavin, lutein, lycopene and orthoeutein. Medical experiments have proved that natural lutein contained in plants is an excellent antioxidant. Adding a certain amount of lutein to food can prevent cell senescence and organ senescence, as well as prevent vision loss and blindness caused by age-related ocular macular degeneration. Through a series of medical studies, carotenoids have been recommended as cancer prevention agents. Life extenders, ulcer preventions, heart attacks and coronary artery disease preventions. At the same time, lutein can also be used as a feed additive for the coloring of poultry meat and eggs, and has also been used in the food industry as coloring and nutritional health agent.

Lutein is a nutrient that can be absorbed by human daily consumption of fruits and vegetables, but the absorption efficiency is generally low. If lutein is deficient, supplements can be taken.

(1) Main pigment components of retina: lutein and zeaxanthin constitute the main pigments of vegetables, fruits, flowers and other plants, and are also the main pigments in the macular region of the retina of human eyes. Human eyes contain high levels of lutein, an element the body cannot produce and must be replaced by ingestion of lutein. Without this element, the eye will go blind.

(2) Protect the eyes from light damage, delay the aging of the eyes and prevent lesions: the ultraviolet and blue light in the sun will produce a large number of free radicals into the eyes, leading to cataracts, macular degeneration, and even cancer. Uv rays are filtered out by the cornea and lens of the eye, but blue light penetrates through the eye to the retina and macula. Lutein in the macula filters out blue light, preventing blue light from damaging the eye. The fatty outer layer of the macula is particularly vulnerable to oxidative damage from sunlight, so this area is prone to degradation.

(3) Antioxidant helps prevent cardiovascular sclerosis, coronary heart disease and tumor diseases caused by aging.

(4) Vision protection: As an antioxidant and photoprotective effect, lutein can promote the regeneration of Rhodopsin in retinal cells, prevent severe myopia and retinal detachment, and improve vision and protect vision. Especially suitable for students, drivers and other people to eat.

(5) relieving symptoms of visual fatigue; (Blurred vision, dry eyes, bulging eyes, eye pain, photophobia, etc.)

(6) Improve the pigment density of macula, protect macula and promote the development of macula;

(7) Prevent macular degeneration and retinitis pigmentosa;

(8) Teenagers in the stage of eyeball development coincide with the heaviest period of school, lutein intake is insufficient or excessive consumption of "light" damage, is the basic cause of nearsightedness, amblyopia incidence of nearly 60%. The addition of lutein is equivalent to adding a pair of "natural sunglasses" in the body, will make the vast majority of teenagers false myopia, amblyopia restore normal vision!
