What is Lutein?
Lutein, also known as carotenoid, carotol, phytolutein, ribosome, marigold flower element and phytolutein, etc., the English name is Lutein, the molecular formula is C40H56O2, and the relative molecular weight is 568.85. Orange-yellow powder, slurry or liquid, insoluble in water, soluble in organic solvents such as hexane.
It is usually found in green leafy vegetables. Lutein itself is an antioxidant and can absorb harmful light such as blue light.
It exists together with zeaxanthin in nature and is the main component of plant pigments such as corn, vegetables, fruits, and flowers. It is contained in the chloroplasts of leaves and can transmit the absorbed light energy to chlorophyll a. Destruction is protective. It is also the main pigment that makes up the macular region of the retina of the human eye.
Lutein is a nutrient that humans can absorb when they eat fruits and vegetables in daily life, but the absorption and utilization rate is generally low. Supplements can be taken if lutein is deficient. For older adults with poor digestive systems, a sublingual spray can be used to supplement lutein. Lutein has been added as a dietary supplement as early as 1996.
Marigold Flower Extract Lutein Benefits
Lutein is an important antioxidant, a member of the carotenoid family (a group of natural fat-soluble pigments found in plants), also known as "phytolutein", which co-exists with zeaxanthin in nature.
(1) The main pigment components of the retina: Lutein and zeaxanthin constitute the main components of vegetable pigments, fruits, flowers, and other plant pigments, and are also the main pigments in the macular region of the human eye. Human eyes contain a high amount of lutein, an element that cannot be manufactured by the human body and must be supplemented by ingesting lutein. Without this element, the eyes will become blind;
(2) Protect the eyes from light damage, delay the aging of the eyes and prevent lesions: ultraviolet rays and blue light in the sun will generate a large number of free radicals when entering the eyes, causing cataracts, macular degeneration, and even cancer. Ultraviolet rays can generally be filtered out by the cornea and lens, but blue light can penetrate the eyeball and reach the retina and macula. Lutein in the macula can filter out blue light and avoid blue light damage to the eyes. The fatty outer layer of the macula is particularly susceptible to oxidative damage from sunlight, so this area is highly prone to degeneration;
(3) Antioxidant, helps to prevent cardiovascular sclerosis, coronary heart disease, and tumor diseases caused by aging;
(4) Protect vision: Lutein, as an antioxidant and photoprotective effect, can promote the regeneration of Rhodopsin in retinal cells, prevent severe myopia and retinal detachment, and improve and protect vision. Especially suitable for students, drivers, and other people to eat;
(5) Relieve visual fatigue symptoms: (blurred vision, dry eyes, eye swelling, eye pain, photophobia, etc.);
(6) Improve macular pigment density, protect the macula, and promote macular development;
(7) Prevention of macular degeneration and retinitis pigmentosa;
(8) Reduce the production of drusen and prevent the occurrence of AMD.
