What are the functions of lutein esters?

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.

Jianshijia bilberry lutein ester is made of lutein ester.

Lutein ester is an important fatty acid lipid that has a carotene-like effect. Lutein ester has antioxidant and blue light filtration, which can prevent damage to the eyes caused by ultraviolet rays or blue light from mobile phones, and has a protective effect on the retina of the eye.

Lutein ester is a kind of carotenoid ester fatty acid ester, often found in marigold flowers, pumpkin, cabbage and other plants, the human body ingests lutein ester, can relieve the eye soreness, redness and other symptoms caused by excessive use of eyes, can also prevent ultraviolet rays or blue light damage to the eyes of electronic devices, so as to achieve the purpose of the effect.

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 benefits it will be 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 protecting 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 insufficiently absorbed, but also extremely utilized, and must be supplemented. Therefore, if you want to supplement lutein, in addition to food, it is best to supplement it through nutritional supplements such as Joyeye Vision Nutrients.

Lutein esters. 1. The efficacy and function of lutein esters.

Lutein ester is essential for our human body, it will be absorbed by our body and then decomposed into lutein, and this substance is not synthesized by ourselves, so we need to ingest it from the outside to supplement our body, so as to protect our eyes, prevent our eyes from being damaged, and relieve our visual fatigue. Usually, we can eat more carrots, papayas and fruits to get lutein esters.

Most importantly, it can also be used in food and cosmetics and other fields, after a series of processes, lutein esters can be made into colorants, so that they can replace chemically synthesized colorants, which can improve our healthy living standards.

Second, lutein ester is suitable for people.

There are many brands and types of lutein ester tablets, which are more suitable for people with blurred eye vision, inability to see clearly and fatigue easily, as well as people who need to delay aging, and finally people with low immunity can also take it, but infants are not suitable for taking it.

Lutein is an antioxidant, which can prevent the body from being damaged by free radicals, and lutein is more abundant in vegetables and fruits, which can protect the retina, increase vision, prevent glaucoma, delay the occurrence of cataracts, prevent the sequelae of high myopia, and reduce macular degeneration, which plays a key role in the protection of the eyes.

Lutein is a very important nutrient for the eyes, lutein exists in the chest, heart, serum, **, and eyes, and its efficacy is also very many.

1. Protect the retina.

Lutein is an antioxidant with a relatively high concentration, which can filter out blue light and reduce color aberration, so that vision can become better.

2. Prevention of glaucoma.

Lutein can also better reduce the oxidation of ocular protein, and the more lutein you consume, the lower the chance of glaucoma.

3. Delay the occurrence of cataracts.

Lutein is a carotenoid, which is stored in the crystal, which can make its resistance to oxidation stronger, and can also resist free radicals and sunlight, so that the probability of cataract is reduced, and the effect of delaying the appearance of cataract is achieved.

4. Prevent the sequelae of high myopia.

Many people have high myopia, so it is easy to have floaters, fluid accumulation and retinal detachment problems, and even permanent blindness.

5. Prevent macular degeneration.

The reason why older people lose their eyes is because of macular lesions, and experiments have found that lutein can improve the problem of degenerative macular disease and reduce the chance of blindness in the elderly.

1. The main intake in the daily diet is lutein, not lutein esters. It is estimated that 80% of the daily intake of carotenoids is free-form lutein, and only about 7% of lutein is in the form of lutein esters.

Second, what is present in human tissues is lutein, not lutein esters. Lutein is one of only two dietary carotenoids that are selectively deposited in the macular region of the retina, where it is called macular pigment. Macular pigment is located in the anterior part of the primate retinal photoreceptors, effectively creating a filter that absorbs light with damaging wavelengths, especially blue light (wavelength 400-480 nm).

Recent studies have found that lutein is the main carotenoid in the brains of the elderly and infants, and is also found in zeaxanthin, breast tissue, ovaries, and uterus, and even in breast milk and neonatal plasma.

3. Lutein can be directly absorbed by the human body, while lutein esters need to be converted. Lutein ester needs to be combined in the small intestine by bile and pancreatic lipase and hydrolytic ester system to produce free lutein, and then absorbed by the small intestinal mucosa to convert into effective lutein. Lutein, on the other hand, can directly enter the stomach and intestines and be absorbed by the body.

4. Pay attention to the comparison of the bioavailability of lutein and lutein esters. A direct comparative study of the bioavailability of lutein esters versus free lutein showed that about 5 times the amount of lutein esters must be consumed to ensure the same level of lutein in the blood compared to free lutein.

5. Lutein instead of lutein ester should be used in research on human health.

The effect is almost the same, all of them are eye protection. Lutein ester is a kind of carotenoid fatty acid lipid, often found in marigold flowers, pumpkin, cabbage and other plants, the human body ingestion of lutein ester, can relieve the eye soreness, redness and swelling caused by excessive eye use.
