Is lutein or lutein ester better? Which one to choose for eye protection?

Lutein, also known as phytoprogesterone, is a high-quality antioxidant, which is widely found in chlorophyte vegetables, fruits, flowers and other plants in the form of esters. You must know that the retinal macula is responsible for the first vision, but the human body cannot synthesize lutein by itself, so it is very necessary for both children and adults to take lutein. The main component of lutein ester is lutein dipalmitate, which exists in an all-trans molecular configuration, and will be hydrolyzed into lutein after entering the human body, which plays the same eye protection function as lutein.

Lutein is the main pigment that makes up the macular area of the retina of the eye, which has antioxidant and photoprotective effects, can promote the regeneration of rhodopsin in retinal cells, prevent myopia and retinal detachment, and play a role in protecting vision. Lutein esters are compounds formed by lutein and fatty acids, which and lutein are both widely found nutrients in nature. Nutritionists found out through experimentsLutein esters can be naturally hydrolyzed into free lutein in the human body, which can then be absorbed by the body.

After reading the introduction of the two, will you think that lutein esters need to be digested by the human body into lutein before they can be absorbed, while lutein can be directly absorbed.

Lutein is very good for eye protection, so we should usually take it in food, eat more green vegetables that contain more lutein, and the fruit effect will be better.

Lutein ester is equivalent to an advanced version of "eye**" lutein, which has better stability than lutein in the "free state". After entering the human body, it will first be broken down and then converted into lutein, and the loss of nutrients is very small, so it is easier to be absorbed and utilized by the body. You can choose nutrients containing lutein esters to supplement, such as Jianshijia bilberry lutein, which has good raw material quality and can effectively play the efficacy and role of lutein esters.

Lutein: Mainly through dietary supplements, it can be obtained from yellow-green vegetables or kiwifruit, mango chicken, egg yolks, etc., and is absorbed directly into the intestinal tract.

Lutein esters: Mainly obtained through dietary supplements, lutein esters are broken down in the body and converted into lutein, which is then absorbed.

Why do you say that lutein esters are better?

Because compared with lutein, lutein esters are better in terms of absorption and utilization, as well as in terms of thermal stability. Lutein ester is a fat-soluble lutein, which has high biological activity in fat, and in the process of ingestion, it will be consumed less by the stomach, so as to ensure our absorption and utilization.

Step 1: Determine whether to use lutein or lutein esters.

Lutein can be directly absorbed by the human body, while lutein ester needs to be converted into lutein in the human body before it can be absorbed. However, compared with lutein esters, lutein can significantly slow down the loss of its content under the conditions of avoiding light, oxygen isolation and low temperature, and the stability of lutein esters is stronger than that of lutein crystals under these conditions.

Therefore, most people generally recommend using lutein esters to supplement.

Step 2: Look at the other ingredients.

At present, the nutrients that are beneficial to the eyes, in addition to lutein, anthocyanins, zeaxanthin, carotene, vitamin A, etc., if it is very troublesome to supplement alone, and it may not be enough, so if there is a comprehensive of these, it can be supplemented, then it is naturally the best, which is why many people will choose Leeye vision nutrients to supplement lutein.

Finally, look at the bright ridge or content of lutein.

At present, the daily intake of lutein is 12mg for Jingwu, and if you eat too much, the body can't absorb it, and it has no effect!

To sum up, let's choose the right lutein, and then consider the price point to be more appropriate.

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.
