Carotenoids are the blue-light absorbing plant pigments are found in red and yellow plants, powered by photosynthesis as well as some kinds of fungus and bacteria. They are valuable antioxidants that help protect the eye from many eye diseases. These antioxidants are used throughout the body, but are found in the highest quantities in the retina or macula of the eye.
is a yellow pigment (from latin meaning, "yellow") which is found in the eye's macula and lens of the eyes. It is created only by plants
and is found in animal foods only because they eat plants. Lutein is an antioxidant that helps protect the eyes from the free
radical damage that UV and blue light from sunlight causes. Lutein is concentrated in the peripheral edges of the retina. It
works most effectively as a supplement in combination with zeaxanthin.1 In addition to supporting the retina, lutein is
important for a healthy lens.
Food sources: yellow and orange foods,corn, kale, spinach, collards and mustard greens, lettuce and salad greens, brussel sprouts, broccoli, and eggs.
Note: The lutein that comes from red/orange fruits and foods support macular pigment density than those from green vegetables.2
is a fat-soluble carotenoid which, in its value as an antioxidant is ten times more powerful than beta-carotene, and up to 500 times stronger than vitamin E. It must be taken in through food or in a supplement since it is not made by the body.
Food sources: It is found in the red yeast Phaffia rhodozyma which is used in Asian cooking, and accumulates in the muscles of salmon, shrimp, trout and other pink seafood that eat the red algae Haematococcus.
Daily Need: It can be taken in pill form, 4-10mg daily.
is also found in high amounts in the macula and like lutein protects against the free radical damage from UV light that damages the retina (macula and rods and cones).
Zeaxanthin is found most concentrated in the center of the macula. It works more effectively as a supplement in combination with lutein.1
