What Is Lutein Good For?

Lutein, also known as plant lutein and carotene, is a type of carotenoid. It is widely found in green vegetables, fruits, flowers, egg yolks and some algae, and has attracted much attention for its powerful antioxidant and eye protection properties. It cannot be synthesized in the human body and can only be supplemented by ingesting external food. It can effectively filter blue light and protect the retina from damage, thereby preventing vision loss and eye diseases. In addition, it has a variety of biological activities such as anti-inflammatory, and has certain benefits for cardiovascular health and skin protection.

Lutein in a broad sense refers to carotenoids xanthophy II, which includes lutein and its isomers zeaxanthin and mesozeaxanthin. Although they have different names, they are essentially xanthophyll II, and can be converted into each other and coexist in a certain proportion. The main industrial source of natural lutein is to extract and saponify lutein esters in marigold to obtain lutein monomers.

As a natural plant pigment with multiple biological activities, it has been widely used in food, medicine and cosmetics. 1g of lutein is equal to the value of 1g of gold, and it is given the reputation of "plant gold".

What Are The Benefits Of Lutein?

Filter blue light: Lutein is the main pigment in the macula of the retina. It can effectively filter blue light, reduce the damage of blue light to the eyes, and protect the health of the retina.

Prevent eye diseases: It helps prevent a variety of eye diseases, such as cataracts, macular degeneration, etc., especially for people who use their eyes for a long time, such as students, IT workers, etc. It is particularly important.

Antioxidant: Lutein, as a powerful antioxidant, can remove free radicals in the body and reduce the damage of oxidative stress to cells, thereby delaying the aging process.

Relieve visual fatigue: It can improve visual function and reduce the symptoms of visual fatigue caused by long-term use of the eyes, such as dry eyes, soreness, blurred vision, etc.

Promote skin health: It can absorb ultraviolet rays, reduce the damage of ultraviolet rays to the skin, and help maintain the normal metabolism and health of the skin.

Anti-aging: As a powerful antioxidant, lutein can remove free radicals in the body, reduce the damage of oxidative stress to cells and organs, and help delay the aging process.

Lower cholesterol: It can lower the level of low-density lipoprotein cholesterol in the blood and reduce the risk of atherosclerosis.

Prevent heart disease: Through its antioxidant and anti-inflammatory effects, lutein helps protect the health of the cardiovascular system and prevent the occurrence of cardiovascular diseases such as heart disease.

Promote liver cell recovery: After liver damage, it can assist in promoting the recovery process of liver cells and support the metabolic activity of the liver.

Enhance immune function: It can reduce the damage of ROS to cell membranes, cell proteins and nucleic acids on immune cells, and help improve the body's immunity.

Promote brain health: Lutein can cross the blood-brain barrier into the brain, protect neurons from oxidative damage, and promote the growth and connection of neurons, thereby improving cognitive function and memory.

Can Lutein Promote Healthy Vision?

Lutein has a significant promoting effect on healthy vision. Through a balanced diet and proper supplementation, it can effectively prevent eye diseases and improve visual function.

Constitute the retinal macular pigment: In the human body, lutein and zeaxanthin together constitute the macular pigment in the retina, which is distributed in the macular area with high visual acuity, producing and maintaining normal vision of the human body.

Filter blue light: Long-term exposure to blue light will damage the eyes, and lutein can form an effective blue light filter in the retinal macular area, absorb blue-violet light with a wavelength of 400-500nm, reduce the oxidative damage of high-energy light to retinal pigment epithelial cells, reduce the stimulation of blue light to the retina, and reduce the risk of diseases such as macular degeneration. It is especially important for people who face electronic screens for a long time.

Antioxidant: Lutein is a powerful antioxidant that can neutralize free radicals in the eyes, reduce the damage of oxidative stress to eye tissues, protect the retina, lens and other structures from damage, and maintain the normal physiological function of the eyes. For example, ultraviolet rays and blue light in sunlight enter the eye and produce a large number of free radicals, which may lead to cataracts, macular degeneration and other diseases. Lutein can reduce the risk of these diseases through its antioxidant effect.

Maintain visual acuity: It is an important pigment in the macula of the retina, which can enhance the absorption and processing ability of the macula to light, making the transmission of visual signals more accurate, thereby improving visual clarity and acuity, and helping people see the details and colors of objects more clearly.

Protect retinal cells: When retinal cells are damaged, lutein can provide nutritional support, promote cell repair and regeneration, and help maintain the normal structure and function of the retina. For patients with early age-related macular degeneration, supplementing lutein can delay the progression of the disease and improve vision.

How Does Lutein Relieve Eye Fatigue?

Improve visual function: Lutein can improve the contrast sensitivity and visual clarity of the retina, which helps to reduce eye fatigue caused by vision problems.

Antioxidant: Long-term use of the eyes will cause the eyes to produce a large number of free radicals, which will attack eye cells, causing cell damage and oxidative stress reactions, and then cause symptoms such as eye fatigue and blurred vision. It is a strong antioxidant that can remove free radicals in the eyes, reduce oxidative damage, protect the health of retinal cells and macular areas, maintain normal physiological functions of the eyes, and thus relieve eye fatigue.

Filter blue light: Blue light has high energy and can penetrate the lens directly to the retina, causing damage and death of retinal cells. Lutein can absorb and filter blue light, reduce the damage of blue light to the eyes, reduce the stimulation of blue light to the retina, and reduce eye fatigue.

Promote rhodopsin regeneration: Rhodopsin is an important substance in the retina and plays a key role in the formation and maintenance of vision. Lutein can promote the regeneration of rhodopsin, allowing the eyes to better adapt to different light environments, improve visual acuity and clarity, and thus relieve eye fatigue.

Increase macular pigment density: Lutein is highly concentrated in the macular area, and supplementing lutein can increase macular pigment density. A higher macular pigment density can enhance the macular area's ability to absorb and filter light, reduce light stimulation to the macular area, and also help improve visual contrast sensitivity and enhance visual function in low-light environments, thereby relieving symptoms of visual fatigue, such as blurred vision and dry eyes.
