With the wide selection of lutein products, some people become skeptical about the effectiveness of these products in various forms. Some sellers make promising claims about their lutein products, but people with poor vision may wonder whether lutein will actually improve vision.
In fact, lutein products can only help patients with bad vision, which is exactly caused by a lutein deficiency. Lutein in the eyes can protect eye tissue from the damage caused by free radicals, which are highly reactive atoms. These free radicals in the eye act on other healthy atoms and damage them, because they require a supply of free electrons. Lutein can effectively fight against these radicals.
In either dry or wet form, age-related macular degeneration is the most common result of these reactive radicals, especially in elderly individuals. And lutein has been found to reverse macular degeneration by combating these radicals and thus improve overall eyesight.
Accounting for 80% of vision defects, dry form of AMD is usually caused by abnormal growth of blood vessels below the retina, which in turn results from reactive chemicals in the tissue. Fortunately, lutein supplements have proven to reverse this condition a lot.
In fact, lutein acts like a neutralizing agent and prevents harmful light rays from damaging the tissue in the macula, which is situated in the center of the retina. As a result, a deficiency of lutein can lead to eye tissue damage.
Lutein is actually only one of the 600 carotenoids in the nature and it is the only one present in the macula of the eye. This lucky carotenoid is available from all the green leafy vegetables consumed by ordinary people every day. A healthy way is to take lutein by eating a nutritious meal every day, including lots of fruits and vegetables.
However, some people have no time to maintain such a balanced diet but they also want to get enough lutein every day. Nutritional supplements are a good choice for those people. It is important to strictly follow the doctor’s instructions on the dosage of these supplements and the way they are administered.

Lutein is one of the carotenoids that are found in many plants and animals. Other pigments in the same family include zeaxanthin, astaxanthin, lycopene, beta-carotene and alpha-carotene. Although lutein and zeaxanthin are most commonly thought to benefit the eyes, other pigments also have antioxidant activity in the human body.
During the past several years, most eye doctors or nutritionists recommended a single-ingredient lutein supplement. They think this kind of supplement is beneficial to the eyes, because lutein is most highly concentrated in the retina. And some lutein supplement promoters are airing ads on television. But latest studies have shown other results.
It is true that some earlier studies have proved the effectiveness of lutein supplement or the combination of lutein and zeaxanthin. These nutrients alone can reduce the risk of developing age-related macular degeneration. These studies have considerably promoted the prevalence of lutein supplements.
However, a recent study revealed something different. It compared the blood level of various antioxidants in people with and without macular degeneration. Researchers found that people with high levels did not have macular degeneration. The result is that the total blood levels of carotenoids offer proper protection against the disease.
Supplement products on the market are quire disappointing. A shocking fact is that some lutein supplements as well as vitamins are synthetic. These vitamins can be basically plastic. In particular, most commercial lutein products at low prices are synthetic.
As mentioned before, astaxanthin is another less common antioxidant associated with macular degeneration prevention. A wholesaler of natural astaxanthin named ALGA technologies reveals that nearly all commercial astaxanthin is made of petrochemical sources synthetically.
There is no doubt that these synthetic chemicals have no benefit to human body. But many customers are told to take these supplements on a daily basis. They believe that these lutein supplements as well as multi-vitamins are good for their health. In conclusion, natural sources of these nutrients should be chosen.

Nutritional supplements are plentiful in the local vitamin store and which one is best for you will vary depending on age, medical condition and dietary habits. Lutein is a water soluble carotenoid that possesses anti-oxidant properties. Age related macular degeneration (ARMD) patients are particularly helped by the intake of additional anti-oxidants like Lutein. It is ingested orally and reached the target organs like the retina via the blood stream. The immediate benefit of Lutein is seen in the increase of macular pigment optical density. This improves visual function.
In addition, Lutein aids in the absorption of high energy, short wavelength light that has been shown to act as a catalyst to Macular Degeneration and cataracts. Since both the retina and the crystalline lens are vulnerable to oxidative damage, Lutein an anti-oxidant, is of particular benefit in preserving these structures and thus maintaining better ocular health and vision. The two foods that have the highest quantity of Lutein in them are spinach and kale.
Individuals who have deficiencies in the amount of macular pigment are especially helped by Lutein supplements. Patients with poor dietary habits are likewise encouraged to take Lutein. Visual function is improved rapidly upon consumption depending on the blood level of Lutein. Furthermore, since filtering high energy blue light increases contrast sensitivity, one can also expect an improvement there with additional levels of Lutein.
In short, young healthy individuals who eat well will probably not see many benefits with Lutein supplements. Since it is water soluble excess amounts will be excreted so there is no harm to taking extra amount. In patients who suffer from ARMD, cataracts and other ocular conditions who are older and eat poorly, Lutein supplements are of particular benefit. As always, consult your physician when taking any medications and supplements.

Fruits and vegetables have another disease-fighting weapon to offer: Lutein. Studies show this carotenoid prevents and, to some extent, reverses vision loss, immune system problems, cancer and cardiovascular disease. With that in mind, load up your plate with foods high in lutein — carrots, corn, kale, spinach, Swiss chard, collard, mustard greens, red peppers, dill, parsley, romaine lettuce, tomatoes, potatoes and red, blue and purple fruits.
Is your vision blurred? I know mine is after sitting in front of the television for a while. In that case, you and I need to eat more lutein-rich foods. A few weeks after consuming more lutein-rich foods or lutein supplements, some normal-sighted people report less glare, improved color vision and sharper vision. This suggests that lutein and its companion carotenoid zeaanthin may save our sight by acting as a shield or filter that helps to absorb harmful light and dangerous molecules, both of which threaten the retinal tissue. Using products for macular degeneration or specialized low vision aids together with lutein helps the most.
Though everyone’s sight could benefit from a diet high in lutein, it can literally save the sight of those who have family histories of macular degeneration and other vision loss problems. If someone in your family has experienced vision loss of sight at an old age, then your high-lutein diet should start long before you reach middle age. In a Houston University study, women with diets high in lutein and zeaxanthin experienced a 19 percent reduced risk of cataracts, while men reduced their risk by 22 percent.
A dietary intake of only six milligrams of lutein per day decreases your chances of developing age-related macular degeneration by 38 percent. Everyone over the age of 50 should be taking lutein supplements. However, if you are already experiencing macular degeneration or other vision problems, a high-lutein diet can still help you save your sight by increasing the density of your macular pigment. Macular degeneration may be stabilized or reversed with nutritional intervention, He later goes on to say, By far, lutein is the number one nutritional treatment for the disease.
Not only will lutein save your sight, it may also boost your immune system and, accordingly, prevent cancer. Healthy people seeking to boost overall immune function should consider consuming 5,000 IU of beta-carotene daily, along with other carotenoids, such as lycopene and lutein. By boosting your immunity, lutein decreases your chances of getting cancer, since development of cancer as a disease is associated with immune system impairment. I know you’ve probably heard this a million times, but just in case you haven’t, I’ll say it again: We all have cancer cells. Cancer cells develop in our bodies all the time, but our immune systems normally remove the malignant cells before they can develop into the symptoms we call cancer. In addition to boosting your immune system, lutein may also fight cancer by both protecting your cells from free radical damage and increasing cell-to-cell communication, thus preventing them from turning malignant.
However lutein prevents cancer, we know it works. People with high-lutein diets at any age decreased their chances of developing colon cancer; additionally, young people with high-lutein diets decreased their chances. Studies show that a diet high in lutein will also decrease your chances of other cancers, including cancers of the lung and breast. Women who have low levels of lutein have a 2.08-fold increased risk of breast cancer, so not eating enough lutein-rich foods can actually harm you.
It’s easy to add more lutein to your diet because it’s found in so many foods. Just refer back to the list you read above. In addition, lutein is seven times more available from vegetables than beta-carotene, Just adding a few more fruits and vegetables to your plate each day may save your sight, boost your immune system, prevent you from developing cancer and reduce your chances of having a heart attack.
