Lutein from the Latin luteus meaning “yellow” is a xanthophyll and one of 600 known naturally occurring carotenoids.
Lutein is synthesized only by plants and like other xanthophylls are found in high quantities in green leafy vegetables such as spinach, kale, and yellow carrots.
In green plants, xanthophylls act to modulate light energy and serve as non-photochemical quenching agents to deal with triplet chlorophyll (an excited form of chlorophyll), which is overproduced at very high light levels, during photosynthesis.
Lutein is a carotenoid antioxidant that can be found in many fruits and vegetables, such as spinach, kale, and corn. It is also commonly taken as a dietary supplement due to its potential health benefits.
One of the key benefits of lutein is its ability to support eye health. It helps to protect the eyes against damage from blue light, which is emitted by electronic screens and the sun. Lutein also helps to improve visual function, especially in people with age-related macular degeneration.
In addition to its benefits for eye health, lutein has also been shown to have anti-inflammatory properties, which may help to reduce the risk of chronic diseases such as heart disease and cancer. It may also help to improve skin health and prevent skin damage caused by UV radiation.
Overall, lutein is a valuable nutrient for maintaining good health, especially for those concerned with eye health and overall anti-inflammatory benefits.
