What is lutein?

Scientific studies have shown that lutein: also known as "phytoprogesterone", co-exists with zeaxanthin in nature and is an important antioxidant. At the same time, it is also the most important nutrient component of the human retina.

Effect of lutein on the eyes:

Protect the eyes from light damage, delay eye aging and prevent lesions: Ultraviolet and blue light from sunlight entering the eyes will produce a large number of free radicals, leading to cataracts, macular degeneration, and even cancer. Ultraviolet rays can generally be filtered out by the cornea and lens of the eye, but blue light can penetrate the eye ball directly to the retina and macula, and the lutein in the macula can filter out blue light to avoid damage to the eyes.

Protect eyesight: Lutein, as an antioxidant and photoprotectant, can promote the regeneration of rhodopsin in retinal cells, prevent severe myopia and retinal detachment, and improve and protect vision.

Alleviate eye fatigue: Lutein can alleviate the symptoms of eye fatigue, blurred vision, dry eyes, eye swelling, eye pain, photophobia, etc.

Lutein cannot be synthesized by the human body and must be absorbed into food or as a nutritional supplement. In addition, the lutein of the child must contain zinc. Because lutein is in the child's body, it must be synthesized through the conversion of zinc and absorbed by the child.

For example, Leyan Vision Nutrient, which is not only rich in lutein, but also contains zinc, is currently the only lutein for children in China, which has been recognized by more and more parents for several years.

Lutein, also known as phytoprogesterone, is a carotenoid with the chemical formula C40H56O2, which is widely found in vegetables, fruits, flowers and other plants, and its chemical formula contains two ketone rings, which are the main pigments present in the macular area of the retina of the human eye.

A variety of green leafy vegetables such as spinach, mustard greens, lettuce, broccoli, winter melon, green radish, corn, etc. contain a very large amount of lutein, and kiwifruit and egg yolk also contain lutein.

However, the content of lutein in the human body is particularly small, once consumed, it must be supplemented in time, and a single food can not be satisfied, and must be supplemented by in vitro nutrients.

Guidance: Leyan Vision Nutrient is rich in lutein, and it has a good effect if you take it consistently. Many children are using it, without any ***, which is the first choice for children's lutein.

The currently known effects of lutein are:

1. Protect the retina and ensure clear vision.

Lutein is a good antioxidant that can prevent the retina from oxidative damage when it absorbs light; It can also protect the microvasculature of the eye and maintain good blood circulation.

2. Improve eyesight.

Lutein is a very strong antioxidant that helps filter out blue light, reduce color aberration, and make vision more accurate.

3. Prevention of glaucoma.

Lutein can reduce the oxidative strength of ocular proteins, and the higher the intake, the lower the incidence of glaucoma.

4. Delay the occurrence of cataracts.

Lutein is the only carotenoid found in crystals, which can enhance the antioxidant capacity of crystals, resist damage from sunlight and free radicals, and delay or prevent the occurrence of cataracts.

5. Prevent the sequelae of high myopia.

High myopia is prone to retinal detachment, hydrops, floaters, etc., and even leads to permanent blindness.

6. Reduce macular degeneration and lesions.

Macular degeneration is a leading cause of blindness in older adults. Lutein has been shown to help improve vision in elderly patients with degenerative macular disease.

Lutein, also known as carotenoids, carotenol, phytoprogesterone, ribhetius, marigoldin and plum lutein, etc., the English name is lutein, the molecular formula is C40H56O2, and the relative molecular weight is. Orange-yellow powder, slurry or liquid, insoluble in water, soluble in organic solvents such as hexane.

Lutein is mainly found in vegetables, although it belongs to carotenoids, but carrots are not the best food for lutein**, the darker the color of vegetables, the higher the content of lutein. Such as kale, green cauliflower, spinach, asparagus, green lettuce, etc., are rich in lutein. Egg yolks are also good lutein providers.

There are several types of foods that contain lutein:

1. Egg yolk. We all know that eggs are called a whole nutritious food, from the shell to the yolk, which has very good nutritional value. Egg yolk is rich in lutein and zeaxanthin, which can make the eyes brighter after eating, and the more yellow the egg yolk, the more hidden benefits it will have for the eyes.

2. Kiwi.

This is a fruit that is recognized as having the most lutein content and has a very good eye protection effect. Long-term consumption of kiwifruit can not only help make ** better, but also prevent eye fatigue. Moreover, the vitamins rich in kiwifruit are high antioxidants, which can help clear the abnormal accumulation of oxides in the body.

3. Corn. In the nutrients of corn, it is not only rich in lutein, but also rich in zeaxanthin, which has a very good effect on the health of the eyes and can help prevent age-related macular degeneration.

4. Spinach and other green leafy vegetables.

The content of lutein in spinach and some green vegetables is also relatively high, but dark vegetables are the most abundant, such as spinach and cabbage, etc., and long-term consumption of these foods can effectively protect our eyes from damage.

However, research has also shown that lutein in food is not only absorbed and concealed, but also has a polar utilization rate, and must be supplemented additionally. Therefore, if you want to supplement lutein with empty pengkai, then in addition to food, it is best to supplement it through nutritional supplements such as Leyan Vision Nutrients.

Lutein ester is extracted from a plant called marigold flower, which is released in the human body and becomes lutein, which is the main component of pigment in the retina and crystal closed hand reed, which can effectively prevent retinal macular degeneration, as well as cataracts.

Lutein is mainly concentrated in the eyes and especially in the retina in the human body. The normal retina appears orange and reddish, which is the color of lutein. The most important function of lutein is to block the entry of the blue spectrum in sunlight.

The blue spectrum has a devastating effect on the retina. Lutein is an indispensable substance for the human body, but the human body cannot produce it itself and can only absorb it from food. As far as I know, now for people on the Internet, "Ye Huang Hui Pupil Tea" is the protector of the eyes, drinking tea while surfing the Internet to ensure the nutrition of the eyes and fight against the invasion of germs and light perception on the eyes, so that the eyes are always in a healthy, bright, normal and comfortable state.
