Lutein and zeaxanthin are two very important antioxidant carotenoids.:
Photo: Normal eye with Lutein [left], AMD eye with less Lutein [right]
Originally, they were to be included in the AREDS formulation of antioxidants, but at the time no reliable commercial suppliers of lutein were available so lutein and zeaxanthin were dropped from the final formulation.
While the AREDS was underway, more evidence emerged to support the theory that lutein and zeaxanthin played an important role in the development and treatment of age-related macular degeneration (AMD).
Carotenoids are the yellow pigments found in fruits and vegetables. Lutein and zeaxanthin are two carotenoids primarily found in dark green leafy vegetables, like spinach. They're also found in the macula of your eyes. Lutein and zeaxanthin make up the bulk of the pigments contained in your macula and yet the only way your body can get them is through diet. In fact, the yellow appearance, and the name macula lutea, is due to the dense concentration of lutein.
If you eat a diet high in lutein, your body will have more of it to absorb and put to use, which is a good thing because scientists have long suspected a link between the amount of lutein in your system, your macular pigment, and the development of AMD. In fact, studies have shown that people with AMD have lower levels of lutein and zeaxanthin in their maculas.
One study in particular has shown that levels of lutein and zeaxanthin naturally decline with age, leveling off at about age 60. This same study also showed that people with AMD had even lower levels of these carotenoids - 32% lower. What's even more interesting is that people who began taking a lutein supplement in excess of four milligrams (4 mg) per day saw their macular lutein levels return to normal.
Another earlier, large scale study showed that people with AMD who ate a diet rich in lutein and zeaxanthin had a 57% lower chance of developing wet AMD. The people in this group consumed close to 6 mg of lutein per day. That's about the same as one large bowl of raw spinach salad per day. Unfortunately, most people, especially seniors, don't come close to getting that much lutein each day. The average diet provides only about one to three milligrams (1-3 mg) of lutein per day.
There are numerous other studies demonstrating the relationship between lutein, zeaxanthin and AMD. Some have shown that the harmful effects of blue light on the retina can lead to AMD. Blue light is a component of natural sunlight and when it reaches the retina, it can be harmful to the photoreceptors and the retinal pigment epithelium, which are essential to vision. A healthy macular pigment acts as a filter, absorbing most of the blue light before it reaches the photoreceptors. Conversely, more blue light gets through to the retinas of people with low concentrations of lutein in their maculas, creating a higher risk of developing AMD.
Taken together, all of these studies demonstrate a strong link between lutein, zeaxanthin and AMD. Anyone with, or at risk of developing AMD, should consult their eye-care professional about taking an AREDS formula vitamin supplement. They should also consider increasing their daily intake of lutein and zeaxanthin, either through diet, or supplements.
Antioxidant Character of Lutein:
Antioxidant Activity:In recent years, carotenoids have received a tremendous amount of attention as potential anti-cancer and anti-aging compounds. Carotenoids are powerful antioxidants, protecting the cells of the body from damage caused by free radicals. Carotenoids, and specifically beta-carotene, are also believed to enhance the function of the immune system.
As an overall antioxidant, Lutein is a key with other antioxidants in the mechanism of preventing the deleterious effects of oxidation processes and fighting against free radicals in the body.
1.Lutein also is the main carotenoid antioxidant identified with the lens of the eye and may play a role in the prevention of cataracts.
2.Lutein has been found to have specific applications for the eye, in maintaining optimum eye health whilst preventing macular degeneration.
Lutein's antioxidant qualities may help promote healthy skin during sun exposure, whether lutein is consumed in the diet or applied to the skin through a growing number of personal care products containing supplemental Lutein.
Marigold (Tagetes Erecta)flower extracts used as nutritional supplement.
Contrary to previous findings, insignificant levels (less than 0.3%) of lutein oxidation products were detected in the saponified extract. This compositional determination is important for the application of marigold extract in nutritional supplements and increases its value as a poultry fee colorant because it contains more biologically useful lutein compounds than previously believed.
Lutein and the Skin. Lutein as skin cancer inhibitor and care skin:
Since commonly agreed and well-known in public sphere of post-modern bio-science that antioxidant levels can actually protect the skin from sun damage and the onslaught of the aging process.
So the presence of lutein and other antioxidants in the skin, togethor with beta-carotene seemed effective in protecting the cells from UVA damage.
also lutein as good antioxidant help to inhibit free radical from skin, and lutein could act as best free radical inhibitor. and help to make skin more clean and health, show good appearance.
Lutein and the Heart. Lutein as inhibitor of LDL cholesterol Oxidizing:
Lutein is found in HDL, or 'good' cholesterol and this mean lutein prevent LDL cholesterol from oxidizing. Evidence from a 1994 study in Circulation suggested that one of the reasons the French have a low risk of heart disease is that they consume foods rich of lutein content like spinach and collard greens.
Lutein as cancer inhibitor and Lutein as inhibitor of tumor:
Lutein consumption has also been associated with reduced risk of heart disease and cancer of the cervix, breast and lungs possibly due to its anti-oxidant ability and concentration of these carotenoids in these body tissues, even during diseased states.
A recent study by Tufts University and Korean investigators revealed a dramatic 88% drop in breast cancer in women who had the highest blood concentrations of lutein.
Lutein and its oxidative metabolites in chemoprevention of cancer:
Carotenoids are abundant in fruits and vegetables and have been proposed as cancer protective compounds because of their antioxidant and provitamin A activities.
Lutein, an abundant carotenoid in many fruits and vegetables but without vitamin A activity, has been shown to possess strong antioxidant capability in laboratory studies. Results from the present clinical study from Beltsville demonstrate that lutein and zeaxanthin, an isomer of lutein, are partially oxidized in vivo to several metabolites. These observations confirm the antioxidant activity of lutein in vivo which supports one of the proposed cancer protective mechanisms of carotenoids. Results and conclusions from these studies will benefit the diet and health community as well as policy makers.
Lutein as cancer inhibitor:
Researchers at the University of Utah Medical School found that the highest consumers of lutein (a mere 2.4mg daily) were 17% less likely to develop colon cancer than those who ate the least (300 micrograms). Generally, the more lutein consumed, the lower the risk. High lutein also has been linked to fewer lung, prostate and ovarian cancers.
In animals, lutein even slowed the growth of breast tumors. In test tubes, it killed cancer cells.
Lutein(Marigold Extract) as enhancer of immunity and inhibitor of Mammary tumors
The effects of dietary lutein from marigold extract on the development and growth of a transplantable murine mammary tumor and onlymphocyte function were investigated. See the Experiment as following:
Mice Experiment of Lutein Against mammary tumor
Mice were fed a diet containing 0.1% or 0.4% of lutein.
In experiment 1,mice were fed on the diets for 3 weeks and infused with mammary tumor cells into the mammary gland. Result show that dietary lutein increased tumor latency and inhibited mammary tumor growth in a dose-dependent manner. The incidence of palpable tumors on day 28 post-infusion and final tumor weight were lower in mice fed lutein.
In experiment 2, dietary lutein enhanced phytohemagglutinin-induced lymphocyte proliferation but had no effect on interleukin-2 production or lymphocyte cytotoxicity. Therefore dietary lutein increased tumor latency, suppressed mammary tumor growth and enhanced lymphocyte proliferation.
Lutein Prevents clogged arteries:Lutein as inhibitor of blood-vessel clogging
A University of Southern California professor, James H. Dwyer, compared the carotid (neck) arteries of middle-aged people. In 18 months, people with the lowest blood lutein had four times the carotid thickening of people with the highest levels. (Thickening is a sign of blood-vessel clogging throughout the body.) Probable reason: Cells bathed in lutein were less likely to help "bad" LDL cholesterol stick to artery walls.
Lutein Delays lung aging:how lutein protect lung and lutein as lung enhancer.
People who eat the most lutein have "younger" lungs According to new research at the State University of New York at Buffalo.
In fact, high lutein shaved one to two years off lung age as indicated by standard lung function tests in 1,616 men and women, ages 35 to 79. (High vitamin E intake also boosted breathing capacity.) Lutein seems especially important for smokers.
Lutein Combats arthritis:Lutein as inhibitor of arthritis
Lutein may even help block osteoarthritis pain and disability in 16 million Americans.
Researchers at the National Institutes of Health of USA recently discovered that people with the highest blood lutein concentration were about 70% less likely to have arthritis of the knee and other joint tissues.
Nutrition for the Eyes:Lutein as AMD inhibitor,Cataract inhibitor,and eyes benefitor.
Health Claims:Proponents say lutein staves off cataracts and age-related macular degeneration (AMD).and AMD is the leading cause of blindness among the elderly.
The Need for Lutein from AMD treatment:
Insufficient levels of lutein in the macula has been linked as a risk factor in the onset of age-related macular degeneration (AMD), the leading cause of irreversible blindness amoung adults over 50. Eye research has also suggested that lutein deposits may reduce the formation of cataracts and retinal diseases.
What is Age-related Macular Degeneration(AMD)?
The two commonest causes of blindness in the elderly age group are CATARACT and MACULAR DEGENERATION.
Numerous studies show that what one eats can have a significant effect on health of the macula. Unfortunately, once a person has macular degeneration, a healthy diet is not enough to deter the progression of this disease. and a kind of Macular Degeneration caused by many reasons and mainly as the name of Aged and appear more oftenly on old person called Age-related Macular Degeneration(AMD). and what is the appearance and symons of AMD?
Age-related macular degeneration (AMD) is the leading cause of irreversible blindness among Americans age 65 and older.
More than half of all Americans experience cataracts, a clouding of the eye's lens.
Preventative measures are important because eye diseases develop over a long period of time. By the time patients are diagnosed with AMD in their 60's or 70's, the disease may have been developing for 20 years or more.
Common Synoms of AMD: Symptoms of macular degeneration are blurred vision, distorted vision or dark spots,dark blindness,etc.
Only the levels of nutrients found in foods and in typical multivitamins are not sufficient to significantly impact the progression of the disease.
And Lutein has beed documentedly and clinically proved under the guidance of modern science with positivism core that act as good inhibitor of AMD. And Why? please read on:
Mechanism of Lutein for against AMD ?
Lutein is an antioxidant carotenoid that occurs in nature with zeaxanthin. Dietary lutein and zeaxanthin concentrate in the eye's macula and lens, as well as the skin, breast and cervical tissue.
Promote Eye Health:
The eyes are repositories for carotenoids with lutein and zeaxanthin concentrated in the retina and lens.
In the eye, lutein is the primary carotenoid present in the central area of the retina, called macula. Lutein is thought to act as a filter to protect the light-sensitive photoreceptor cells (cone cells) in macula from potentially damaging forms of light and light-originated free radical damages. Dietary lutein is considered an essential micronutrient for normal vision.
How it Works?
Your body uses lutein to make macular pigment (MP) in your retina, and this substance protects your eyes from the sun's harmful blue light rays, which can damage your retina and lead to AMD. MP shields your eyes like a pair of sunglasses, explains Richard Bone, Ph.D., a lutein researcher at Florida International University in Miami. Lutein, an antioxidant, also fights the free radicals that contribute to eye damage.
Like beta-carotene that makes carrots orange and lycopene that makes tomatoes red, lutein is a carotenoid. Lutein is the pigment that makes corn yellow, and lutein gives marigolds their brilliant golden color. One of the most interesting aspects of the way carotenoids interact with the human body - beyond their broad spectrum antioxidant activity - is their tendency to be "organ specific." Different carotenoids have an affinity for different organs in the body. In the case of lutein, lutein is found concentrated in the structure of our eyes.
Both lutein and zeaxanthin protect the macula from degeneration normally associated with aging and oxidative stress. The macula is located behind the lens of the eyes, and it is responsible for focus and color differentiation.
Lutein is especially important to relieve eye disorders, such as Macular Degeneration and cataracts. Lutein and Zeaxanthin are deposited specifically in the macula of the eye, and its role postulated to prevent photo-oxidation. Macular Degeneration is the leading cause of blindness in adults over the age of 40 years old, for which there is no cure or treatment.
Utilizing Hero chromatic flicker photometry to determine macular pigment levels, researchers from the Netherlands found that lutein ester supplements increased macular pigment optical density, a significant finding since the macular pigment may protect against AMD.
Lutein and benefit of lutein to the retina of eyes:
Science has shown that lutein is a primary component of the macula, an area within the retina in the human eye. This macular lutein may protect eyes from some of the damaging effects of the sun by filtering blue light. Healthy lutein levels also help counteract the gradual deterioration of the macula from aging. Such damage to the macula can result in the onset of AMD, or age-related macular degeneration, the leading cause of vision loss in western populations.
The process of vision involves light being focused through the lens and onto the retina, the paper-thin tissue lining the back of the eye-ball. The central portion of the retina, called the macula, receives the most light. Its millions of cells produce the sharp vision needed to read and see objects clearly. With age, tiny blood vessels grow over this area, causing a gradual distortion and loss of vision.
This degeneration of the macular region of the retina is the leading cause of irreversible visual impairment in the USA today. It affects almost 20% of people past the age of 65. Research has shown that these people have lower than normal amounts of macular pigment, which suggests the protective role played by these pigments. In fact, the latest research suggests that low levels of mac-ular pigment is a cause, rather than a result, of macular deterioration.
More Experiment and Report prove that lutein has super ability to inhibiting AMD,so please read on:
Report1:Research compared the macular pigment levels of healthy eyes with those eyes of people with AMD. The researchers report that for the first time, they were able to objectively measure lutein and zeaxanthin levels in the eyes of living people in a large clinical study. Bernstein measured macular carotenoid levels in 93 eyes from 63 patients with AMD and in 220 normal eyes from 138 volunteers using resonance Raman spectroscopy.
The researchers found that macular carotenoid levels decline with age, reaching a stable low level after the age of 60, the age when AMD incidence begins to rise dramatically. They also found that macular pigment levels in the eyes of AMD patients not consuming high-dose lutein supplements were 32 per cent lower than elderly normal eyes.
Lutein acts as a yellow light filter in the eye, accumulating in tiny amounts directly in front of the cones of the retina, in an area called the macula. Macular disease patients experience a slow progressive loss of central vision, a loss of color vision, and difficulty reading and recognizing faces. About 10 million senior Americans show signs of macular degeneration and about four million have lost a significant amount of their central vision.
A 400-500% increased risk for macular degeneration is also experienced by postmenopausal females. Eighty-three percent of ophthalmologists recommend antioxidant supplements for their macular disease patients, but until recently these were zinc-based formulas that did not include lutein. Now researchers have found that adults who consume six milligrams of lutein daily from their diet have a significant decrease in their risk of developing macular disease.
Researchers studying macular degeneration as well as lung cancer are finding that supplementing with less beta-carotene and more lutein gives better results. This could be explained in part by the fact that these fat-soluble carotenoids compete for absorption and transportation. One answer might be to take these two nutrients each day at different meals. Beta carotene remains an important antioxidant nutrient. For instance, it may be more important in helping another eye disorder, retinitis pigmentosa. This is characterized by a progressive loss of night vision. Carotenoid blood levels of individuals with a diet high in fruits and vegetables were 20% lutein, 20% lycopene, 10% beta carotene and 6% alpha carotene and the remainder other carotenoids.
Why necessary to taste lutein and the damage of less lutein in body?
Because the human body does not naturally manufacture lutein, people must rely on lutein-rich foods or lutein supplements to maintain optimal levels of lutein in the eye. A 1994 Harvard University study showed six milligrams of lutein, equal to about one-third cup of cooked spinach, is likely to be a beneficial daily amount in reducing the risk of AMD. If you're not going to get that amount daily, it won't hurt to add a multivitamin that includes lutein, says Robert Abel, M.D., a leading ophthalmologist practicing in Wilmington, Del., and an advisory board member of the Lutein Information Bureau.
So,We know Lutein supplementation may be beneficial for the management of age-related macular degeneration, the leading cause of blindness in older people. Studies show that people who eat more lutein-containing foods appear to be less likely to develop macular degeneration.
Lutein supplements absorb better when taken with meals. Thus far, no lutein toxicity or side effect has been found.Observational studies have noted that higher dietary intake of lutein and zeaxanthin is related to reduced risk of cataracts and age-related macular degeneration, two eye conditions for which there is minimal options when it comes to effective prevention. Researchers speculate that these carotenoids may promote eye health through their ability to protect the eyes from light-induced oxidative damage and aging through both their antioxidant actions as well as their ability to filter out UV light.
What is Night Blindness?
Night blindness is one of the most common vision problems night blindness. Vitamin A is actually a cure for this condition. Triple B SuperVision contains adequate dose of Vitamin A in its natural precursor form, beta-carotene.
Lutein (a member of xanthophylls) is an antioxidant and consists one of a large group of over 600 compounds known as the carotenoid pigments. These pigments give yellow, green or orange coloration to vegetables and fruits and they are precursors for Vitamin A. Lutein is naturally found in egg yolk, and several plants including some flowers, red peppers, collard greens, kale, leeks, peas, romain lettuce, mustard and spinach.
In the eye, lutein is the primary carotenoid present in the central area of the retina, called macula. Lutein is thought to act as a filter to protect the light-sensitive photoreceptor cells (cone cells) in macula from potentially damaging forms of light and light-originated free radical damages. Dietary lutein is considered an essential micronutrient for normal vision. Lutein supplementation may be beneficial for the management of age-related macular degeneration, the leading cause of blindness in older people. Studies show that people who eat more lutein-containing foods appear to be less likely to develop macular degeneration. Lutein supplements absorb better when taken with meals. Thus far, no lutein toxicity or side effect has been found.
Additional Note Evidence:
Several large-scale observational human studies have found a correlation between a lutein-rich diet and healthy eyes. Placebo-controlled studies on lutein have not been done, and researchers have not yet tested lutein supplements in the lab.
Case1:One eight-year observational study of 36,644 men published in the American Journal of Clinical Nutrition in 1999 found that those men who consumed lutein-rich foods more than twice a week had 19 percent fewer cataract surgeries than those who ate fewer lutein-rich foods. A smaller study in Ophthalmology last October reported similar results.
Case2:Another observational study, published in the Journal of the American Medical Association in 1994, analyzed the dietary intake of carotenoids (including lutein) for 356 people with advanced AMD and 520 people without AMD. More of the participants who didn't have AMD consumed more daily servings (six or more) of carotenoid-rich foods (especially spinach or collard greens) than participants who had advanced AMD.
Case3:One study using lutein supplements resulted in a 15% increase in macular pigment levels after 72 days.
Case4:In another study, people who consumed the equivalent of 6 mg of lutein per day were 40% less likely to experience macular problems.
Case5:Another study using sets of identical twins demonstrated that macular lutein concentrations were related to dietary lutein. After consumption, lutein is found in significant quantities in blood serum, suggesting high bioavailability.
Lutein Study Results
According to Nutritional Outlook, a magazine dedicated to reporting on the creation, production, and distribution of nutritional supplements, eye health is one of the leading consumer health concerns in the United States. The focus of much of this concern is age-related macular degeneration or AMD. It affects more Americans than cataracts and glaucoma combined, and is caused by the deterioration of the central portion of the retina, often the result of damage done by harmful UV rays and free radicals.
Researchers believe that some natural antioxidants may be the key to reducing the risk of AMD. Two such antioxidants are lutein and zeaxanthin, which can be found in dark green, leafy vegetables like spinach and collard greens. These are the only two carotenoids found in the retina.
The relationship of lutein and macular health is strong because of the specific deposition of the macula. As an antioxidant, lutein deposits in the macula, the part of the eye that controls vision, and helps filter out harmful blue light preventing it from reaching and damaging the sensitive back tissue of the retina." Lutein and zeaxanthin can also be found in supplement form, usually derived from marigold flower concentrate.
For reasons scientists have yet to pinpoint, parts of the retina and the macula become diseased. As AMD progresses, tiny, fragile blood vessels begin to develop in the retina. These vessels often leak blood and fluid that damages the retina even further.
Blurred vision may be the first symptom.
Straight lines begin to appear crooked.
Dark or empty spaces may block central vision.
Lifetime Wellness Is Key. Everybody assumes their vision will worsen as they age. Most people are surprised to learn they can promote healthy vision before they reach 65.
Lutein in the diet can play a role in maintaining healthy eyes.

Dosage:How much lutein is enough? Dosage:6mg daily.
Nutrition experts currently use 6 milligrams a day as a reliable guideline.
A simple prescription of 10 mg. Of lutein per day could mean the difference between being able to see and not being able to see.
The two commonest causes of blindness in the elderly age group are CATARACT and MACULAR DEGENERATION.
Clinical trials have shown a direct relationship between Macular degeneration and Carotenoid deficiency. The autopsy of eyes with age related macular degeneration have shown 30% less Lutein and Zeaxanthin as compared to healthy eyes. Within 5 months of consuming 10 mg. of Lutein per day, the pigment level of Macula increased by 20% in a small clinical trial.
Lutein has also shown to be effective in preventing Cataract.
Hence, a simple prescription of 10 mg. Of lutein per day could mean the difference between being able to see and not being able to see.

What are current public health recommendations for lutein, zeaxanthin and carotenoids?
To date, no recommended dietary intake levels have been established for lutein, zeaxanthin and carotenoids. In an effort to set such recommendations, the Institute of Medicine at the National Academy of Sciences reviewed the existing scientific research on carotenoids in 2000.
Despite the large body of population-based research that links high consumption of foods containing beta-carotene and other carotenoids with a reduced risk of several chronic diseases, the Institute of Medicine concluded that this evidence was not strong enough to support a required carotenoid intake level because it is not yet known if the health benefits associated with carotenoid-containing foods are due to the carotenoids or to some other substance in the food.
However, the National Academy of Sciences supports the recommendations of various health agencies, which encourage individuals to consume five or more servings of fruits and vegetable every day.
Lutein is usually found in the following types of products:
Eyecare formulas:These products feature a number of nutrients that protect vision. Products may include 6 milligrams of lutein.
Multivitamin formulas:Check the label to see if lutein is included.
Single nutrient:Some products contain only lutein, 6 milligrams or more.
Lutein Absorb:Serum response of lutein in humans after ingestion of a lutein supplement or spinach.
A study was conducted in healthy men to investigate the blood levels of lutein (a pigment found in spinach) after eating a single large oral dose or spinach. Subjects ate an oral dose of pure lutein supplement or chopped, cooked spinach containing an equal amount of lutein, with a liquid diet containing fat. The amount of lutein that appeared in the blood was significantly greater in both the lutein supplement and spinach groups when compared to a control group, but was not different between the two experimental groups. These data suggest that the amount of lutein that gets into the body from supplements is similar to that contained in spinach when eaten as part of a fat containing diet.
