Lutein is a naturally occurring carotenoid. It plays an important role in keeping our eyes healthy and supporting good vision, as well as helping support our skin.
Lutein and zeaxanthin are similar because they both belong to the xanthophyll family of carotenoids. They are both found in the macula and lens of the human eye. They act as powerful antioxidants, and they help filter out damaging, high-energy blue light.
Lutein and zeaxanthin are chemically similar in—fact, both have the exact same chemical formula. They are the major components of the macular pigment in the retina. The macula is a small, heavily pigmented area of the retina responsible for our central, high-resolution vision. Both lutein and zeaxanthin are natural, fat-soluble, yellowish pigments found in plants, algae, and bacteria.
Dark green leafy vegetables contain the highest amounts of lutein. Brightly colored fruits and vegetables also contain a reasonable amount of lutein.
- Lutein nutritionally promotes the health of your eyes.
- Lutein is not made in the body and must be obtained from dietary sources.
- As we age, the body's natural supply of this vital carotenoid can decrease, especially if dietary intake is insufficient.
- Lutein has antioxidant properties and is found in the macula of healthy eyes.
- Scientific evidence indicates that lutein helps filter out high-energy light from the sun and artificial light, which may otherwise induce oxidative stress and possible damage to the eyes and skin.
- Lutein can accumulate in cell membranes of the central nervous system, where it may support cognitive health.
- Lutein promotes healthy skin and skin hydration.
