What is the big difference between lutein and lutein esters, and which is better?

Difference between lutein and lutein esters:

1. Differences in nature.

Lutein is a plant lutein, which is a very good antioxidant. Lutein ester is different from lutein in that it is a fatty acid that is a type of carotenoid. These two substances are fundamentally different, so please don't confuse them anymore.

Second, the difference in efficacy.

Lutein is a good antioxidant, then it has an anti-aging effect, it can fight cardiovascular sclerosis and other diseases. Lutein also contains more carotenoids, so it also has an eye protection effect, which can protect our eyes.

Lutein is not equal to lutein esters, which need to be digested by the human body into lutein before they can be absorbed, while lutein can be directly absorbed. In general, the market price of lutein is higher than that of lutein esters.

Generally speaking, the preventive effect of lutein ester in children is more obvious, and it can be used for daily health care such as the prevention of myopia in adolescents and the prevention of macular degeneration in middle-aged and elderly people.

Although there is a big difference between lutein and lutein esters, there is a connection between the two, and the link between them is that lutein esters can be converted into lutein.

Lutein esters are better, and Jianshi can be.

Lutein esters and lutein should not be taken for a long time, the difference between the two is:

Different absorption methods, different stability, different acid resistance, different absorption rate and absorption amount. Lutein can be directly absorbed by the body, while lutein ester needs to be converted before it can be absorbed by the body.

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.

Lutein ester is an important carotenoid fatty acid ester with small particles of dark reddish-brown color. Most of the lutein esters existing in nature can be divided into trans-lutein esters and cis-lutein esters, which are basically all-trans molecular configurations.

All-trans lutein esters can be divided into: lutein monoester and lutein diester. It is widely found in plants such as marigold flowers, pumpkins, kale, and shou bai.

Among them, it is most abundant in marigold flowers, up to 30% to 40%. In marigold flowers and other plants, lutein is generally combined with fatty acids (such as lauric acid, palmitic acid, etc.) to form esters.

Difference Between Lutein Ester and Lutein

1. Different absorption methods.

Lutein is mainly obtained from the daily diet (corn, spinach, egg yolk, carrot, mango, kiwifruit, grapes, oranges, etc.), which can directly enter the intestine and be absorbed by the body. However, lutein esters are extracted from marigold flowers, which are first decomposed into the human body and then converted into lutein and then absorbed by the body.

2. Different acid resistance.

Lutein has poor acid tolerance, and it is easy to be dissolved by gastric acid after direct consumption, affecting human absorption; The consumption and loss of lutein esters through the stomach after consumption is very low and does not affect the absorption of the body. To put it bluntly, if you are not studying what the use of lutein is for the eyes in the laboratory, it is better to eat lutein esters, after all, only efficient absorption can effectively protect the eyes.

3. The absorption rate is different.

Lutein esters are much higher than lutein in terms of absorption and utilization. Lutein ester is a fat-soluble lutein with high biological activity in fat, so it is normal for lutein ester to have a 60% higher absorption rate than lutein.

The light and heat stability of lutein itself is not as good as that of lutein esters, so the utilization rate of lutein is also low. The stability of lutein ester in terms of light and heat is better than that of lutein.

Scientific Supplementation of Lutein:

Lutein ester and lutein are not recommended to be eaten for a long time, both are to supplement the loss of lutein in the body, our body is lacking what to make up for what, not too much or too little.

Lutein cannot be synthesized in the human body and needs to be ingested from the outside world, while eating corn, yellow-green vegetables, fruits, etc. can supplement the lutein needed by the human body. At the same time, the required lutein can also be obtained by eating eye care products containing lutein.

In addition, it is also very particular when buying eye care products that contain lutein. There are many lutein products on the market, and the purification technology of lutein still needs to be improved. Therefore, lutein products rich in lutein and lutein esters have their own advantages, and consumers can choose according to their needs, but when purchasing, it is recommended to choose lutein products from big brands.

The above content refers to People's Daily Online-eye protection needs to be scientifically supplemented with lutein.

Each capsule contains 5mg of lutein ester, which is conducive to human absorption.

I heard that the stability and absorption rate of lutein esters are higher than lutein, if you need to add them, it is recommended to choose lutein esters, such as Yiyoushanjia's lutein ester blueberry gel candy. There's also a lot of relevant information.

Lutein is the only carotenoid in the eye, and I have taken Genicview Bilberry Lutein Ester-Carotene Softgels before. The eye protection effect is very good, and my colleagues at the time said that my eyes didn't look like they were nearsighted.

Lutein is insoluble in water and propylene glycol, slightly soluble in oil and n-hexane, soluble in acetone, dichloromethane and ethanol, soluble in ethyl acetate, tetrahydrofuran, chloroform, etc., and its stability in solvents is anhydrous ethanol "ethyl acetate" tetrahydrofuran "toluene.

Lutein is found in many vegetables and fruits, and is found in many types of green vegetables. Such as spinach, cabbage, broccoli, etc. The richest food with lutein is kiwifruit, followed by yellow corn and egg yolk.

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 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.
