Lutein, the Eye-protecting "Treasure"

CAS: 127-40-2

Appearance: Orange powder

Lutein, also known as marigold flower extract, is a carotenoid and a photosynthetic pigment. It is naturally present in vegetables (such as spinach, cabbage, broccoli, etc.), flowers, fruits and other plants. It can transfer the absorbed light energy to chlorophyll A in a special state for it to convert light energy, and it has the function of protecting chlorophyll.

It is the most important nutrient for the human retina. The macula (vision center) and lens of the retina contain high concentrations of lutein, which cannot be synthesized by the human body. It must be absorbed from food and then enter the lens and macula of the retina to play an antioxidant role, neutralize harmful free radicals, filter out blue light that is destructive to the eyes, and avoid oxidative damage to the eyes caused by light. Natural lutein is an excellent antioxidant. Adding an appropriate amount to food can prevent cell aging and organ aging, as well as prevent vision loss and blindness caused by age-related macular degeneration of the retina. At the same time, it can also be used as a feed additive for the coloring of poultry meat and eggs, and as a coloring and nutritional health agent in the food industry.

Lutein is a precursor of NA and can be converted into VA in the human body. The main physiological function of lutein to the eyes is as an antioxidant and photoprotective agent. The optic nerve cannot regenerate and is very susceptible to damage by harmful free radicals. The antioxidant effect of lutein can inhibit the formation of harmful free radicals. Lutein (marigold extract) can absorb a large amount of blue light. The wavelength of blue visible light is close to that of ultraviolet light, and it is the most potentially harmful type of visible light that can reach the retina. Before reaching the sensitive cells on the retina, the light first passes through the highest concentration area of lutein. At this time, if the lutein content in the macula is rich, the damage could be minimized.
