The Importance of Lutein
Lutein (pronounced LOO-teen) is a carotenoid, meaning a natural colorant or pigment, found in dark green leafy vegetables such as spinach, plus various fruits and corn. Egg yolks are also sources of lutein.
Lutein has been linked to promoting healthy eyes by possibly reducing the risk of macular degeneration eye disease. Within the human eye, lutein deposits itself in the macular region as well as the entire retina, ciliary iris bodies and lens.
Lutein also filters the high-energy, blue wavelengths of light from the visible-light spectrum. Blue light, in both indoor lighting and sunlight, is believed to induce oxidative stress and possible free-radical damage in human organs exposed to light, such as the eyes and skin. Blue light is not the same as the commonly known ultraviolet A and ultraviolet B wavelengths of the invisible spectrum.
Lutein has been found in the eye, serum, skin, cervix, brain and breast. Lutein is an antioxidant that appears to quench or reduce harmful free radicals in various parts of the body. Free radicals can play a role in a variety of chronic diseases.
Most Americans do not get enough lutein in their diets. Research has suggested 6 mg of lutein per day is necessary to maintain healthy eyes. Total Focus supplies 12 mg to realize additional health benefits. No lutein side-effects have been reported.
