Understand the Benefits of Lutein for Eye health

Lutein Benefits: How can it improve eyesight?

Lutein is an antioxidant nicknamed “the eye vitamin”, because of its popularity in protecting eye health.

Most importantly, Lutein with eye vitamins makes some best vitamins for macular degeneration.

Like any other body organ, our eyes also need different nutrients for optimal health. Lutein is one of the key nutrients that contain anti-inflammatory properties. These properties make this carotenoid a key nutrient for improving eye health.

Despite the growing popularity of lutein supplements with eye vitamins, many people are still determining what it is. Therefore, here we have brought a comprehensive guide for you to consider.

So, here we go:

An introduction to Lutein

Lutein is a carotenoid antioxidant. Carotenoid is a phytonutrient type which is a plant chemical that you can find in multiple plant types. Moreover, carotenoids also cause vibrant colors in various plants such as bright yellow, orange, and red hues of different fruits and vegetables.

These pigments don’t only play an important part in plant health. In fact, these also provide benefits to eye health.

Most importantly, zeaxanthin and Lutein are the two carotenoids available in our retina. Both of these are found concentrated in the macula region mainly. This region is available in our eyes’ backside, which plays a key role in vision. Due to their placement in the eye, these molecules are familiar as macular pigments.

Moreover, these molecules are also familiar to work as a light filter. It means these work to keep the eye tissues protected from sun-caused damage.

Fortunately, lutein is also available in a variety of foods including vegetables and fruits. However, people commonly use lutein supplements to protect their eye health. The oral lutein supplement can also help in protecting you from various eye problems. These problems more often include ailments that can cause vision loss in the elderly, such as age-related macular degeneration.

Moreover, lutein is also familiar with various other health benefits. However, the scientific evidence supporting the benefits of lutein is less comparatively. In fact, more research is required to understand the impact of lutein in other health areas.

Why is Lutein good for eyes health and how it works?

Lutein is not only a potent antioxidant that you can find in various veggies and fruits but is also available in our eyes. The fact is truer, especially for the eye's lens, macula, or retina. Therefore, many of us believe that lutein is a good anti-oxidant for better eye health. Moreover, it also plays an important role in our vision.   

In addition, zeaxanthin and lutein can protect our eyes from harmful light waves with high energy. These include UV rays in sunlight.

  • Moreover, studies suggest that a high level of lutein in both eyes is linked with improved vision. This statement is truer, especially when you are in dim light and the glare.
  • Diets containing a rich amount of zeaxanthin and lutein can also help reduce age-related eye problems. For example, a research study suggested that people who consume lutein and zeaxanthin-rich foods such as green veggies are less likely to get cataracts.
  • Another research study has shown consuming a supplement with zeaxanthin and lutein can slow down the progress of macular degeneration. Macular degeneration is an eye condition that can damage your retina’s middle eye and take the central vision away.

Besides that, various research studies have also shown the effectiveness of these two nutrients combined with other nutrients. For example, vitamins E and C. It may be because consuming a mix of nutrients can better protect your eye health.

Lutein benefits for different eye conditions

In combination with zeaxanthin, Lutein can benefit you regarding the following eye conditions. Let’s indulge in the details below to understand the lutein benefits regarding different eye conditions.

So, here we go:

Age-related macular degeneration

Lutein is a lucrative nutrient that is a popular treatment for age-related macular degeneration. This problem is familiar as the most common yet popular blindness cause among older adults.

According to estimates, above 25 million people across the world are affected by age-related macular degeneration. The statistics are especially truer for people 55 or older who live in industrialized western parts.

According to AOA (American Optometric Association), it’s also estimated that the AMD is expected to rise 3x by 2025.  

Fortunately, Lutein can protect your eyes by filtering out some damaging UV light (short-length). This short-length UV light can affect your eyes’ delicate parts, such as the retina. According to Harvard University, researchers found that using lutein supplement daily can reduce macular degeneration’s risk.

Besides that, some other studies also show that lutein and zeaxanthin dietary intake can also improve vision in older people.

Diabetic retinopathy

Moreover, diabetic retinopathy can also impact one-third of people who already have diabetes. The research on the effectiveness of lutein regarding diabetic retinopathy is limited yet. However, animal research has shown that lutein can reduce oxidative stress markers. These stress markers can otherwise cause vision loss or eye damage.

Dry eye disease

Dry eye is another serious eye problem that occurs due to insufficient tear production. The condition can cause discomfort, redness, and impaired vision in your eyes.

Moreover, research has also suggested that people who suffer from eye tiredness can benefit from consuming lutein supplements. Consuming lutein can lead to a reduced score of overall eye fatigue. 

Moreover, lutein can also help in improving tear production. It can also cause increased macular pigment optical densities and reduce other symptoms of dry eyes.

Cataracts

The clouding in the lens of the eyes is familiar as cataracts. Moreover, it is also a key contributor to blindness worldwide. According to the survey, people consume more zeaxanthin, and lutein has decreased cataract prevalence.

Moreover, other research studies have shown the same benefits of using Lutein to reduce cataract risk.

Other eye conditions

Besides these eye health conditions; lutein can also protect your eye health in various other ways. According to research, lutein can help your eye health in different ways.

These include:

  • Lutein can suppress inflammation.
  • It provides a defense against oxidative stress and free radicals.
  • Lutein can enhance your vision’s sharpness.
  • It can also improve the visual contrast sensitivity of the consumers.
  • This nutrient can also decrease glare impairment.
  • It protects your eye tissues against sunlight damage
  • Lutein is also effective in reducing cell loss and fatal eye diseases.
  • This nutrient also works amazingly to protect your eyes from dangerous blue light.
  • Lutein converts light signals in your retina into electrical signals and helps transmit these signals to your brain’s visual cortex.
  • It also protects against myopia and protects pre-term infants against ROP effects.

Whenever it’s about using lutein for eye protection, the lutein benefits are different for every person.   

 

Other health benefits of Lutein you should know about

Arguably, lutein is a carotenoid that’s highly important for vision and eye health. However, the benefits of lutein continue beyond here. Besides protecting your eyes, there exist various other health benefits of lutein that you must know.

For instance, it can help prevent skin disorders, cancer, coronary heart disease risks, and type-2 diabetes.

Do you want to know what other benefits of lutein you can expect to enjoy? Then have a look at the health benefits of lutein enlisted below.

So, here we go:

Protects against skin problems  

Lutein is not only available in our eye pigments. Instead, you can also find these carotenoids within your skin. Lutein can help the skin to filter high-energy waves of visible light. This practice can help the body to slow down the oxidative stress rate. Moreover, lutein can also help improve our skin health and fight to reduce the risk of skin cancer.

According to some animal research studies, lutein can significantly protect our skin against skin damage caused by induced light. These conditions otherwise can lead to aging signs and a higher potential of developing skin cancer.

Lower diabetes risk.

Fortunately, lutein can also help in reducing the risk of type-2 diabetes.

According to some animal-based research studies, higher carotenoid levels within our blood are linked with reduced problems in controlling blood sugar levels throughout our body. Moreover, it can also reduce the chances of other complications.

Another research study from 2009 conducted on rats with diabetes found that DHA and lutein supplements can also help normalize all types of diabetes. The fact is truer for biochemical modifications induced by diabetes.

In this controlled study, diabetic rats who consumed lutein supplements experienced reduced oxidative stress rates. These rats also experienced lower damage to their eyes’ retinas besides experiencing hyperglycemic conditions.

Lowering the risk of cancer.

According to some evidence, people consuming lutein from dietary sources experience reduced cancer risk. These include lung cancer, breast cancer, and colon cancer. Even though currently the correlation between lutein and cancer formation is not clear yet. However, research studies have found that adults with lutein’s higher levels in the blood experience lower chances of developing common cancer types.

According to a study from 2018, supplementation of dietary lutein is a promising alternative against breast cancer.

Moreover, lutein also acts as a natural treatment for cancer. It is also because lutein-rich foods offer other nutrients and antioxidants that can reduce oxidative stress and disease-causing inflammation.

Still, more research is needed to understand carotenoids' effects on cancer.

Boosting memory

As per a University of Georgia study, people who consume lutein find it easier to perform memory-related tasks than others. A higher level of lutein can help the brain in retaining specific information.

Moreover, a University of Illinois study suggests that consuming high lutein levels is helpful in preserving crystallized intelligence. Crystallized intelligence is the ability of someone to remember skills that they have learned throughout their lifetime.

Lutein deters cognitive decline.

Are you someone who struggles to finish a crossword? Then it is a smart choice to get more greens inside. According to a 2017 study performed on adults between 25 to 45, older participants with higher lutein levels consumption through their diets had cognitive responses the same as the younger volunteers in that study.

Benefits your heart health.

According to some observational studies, lutein and other xanthophyll carotenoids can reduce the risk of stroke and heart problems. Lutein also contains antioxidant and anti-inflammatory properties. Due to these properties, it seems beneficial for heart health by reducing inflammation.

According to the University of Southern California, studies suggest that reduced lutein levels in the blood contribute to artery wall thickening. This problem can ultimately increase arteriosclerosis development and carotid artery clogging risks. Both of these conditions can cause heart attacks.

These observational studies have shown that people with the highest lutein levels in blood experience reduced plaque buildup in arteries. On the other hand, less lutein consumption means increased risks of clogged arteries.

What amount of lutein do you need per day?

Even though researchers don’t specify any certain lutein dietary intake recommendations. Moreover, lutein consumption is familiar as safe, even in higher amounts. The FDA has classified Lutein as GRAS (Generally Regarded as Safe).

It has been estimated that Americans consume about 1 to 2 mg of lutein daily. However, research suggests you may need a higher lutein intake to reduce the risk of developing AMD.

Moreover, according to the research for other eye diseases related to age found, lutein’s 10 mg is effective to intake.

In addition, as per Council for Responsible Nutrition, intaking a 20mg lutein dose is safe. For more details, may visit our article: Recommended Dosage of Lutein.
