How to choose lutein and which is better? How to choose

Before purchasing, we need to compare several companies in detail, and then consult the merchant to understand lutein.

The content of the active ingredient is very important. Because lutein products play a role in the active ingredient of lutein.

Generally, the lutein products on the market are labeled as marigolds, the raw material of lutein.

This does not represent the content of lutein. Be careful about this.

After the comparison, it's **. The ** of lutein on the web ranges from tens to hundreds. So, what is the best and most suitable?

The home page should exclude less than 100 yuan, why? Because the content of lutein active ingredients below 100 yuan simply does not meet the requirements. The WHO recommends that the daily intake of lutein is more than 20mg, according to this 100 yuan or less, the content of lutein will not be 2mg per tablet, so to meet the standard intake, eat more than 10 tablets a day, too troublesome.

Secondly, it is more than 100 yuan to 200 yuan, and the lutein content is generally more than 5mg per tablet, so that you can eat 4 tablets a day, which is simple and convenient. This is more recommended.

Lutein, also known as "eye**", is the most important nutrient in the human retina. It is mainly distributed in the retina and lens, especially in the macular part of the retina, where lutein content is the highest.

It depends on the content and ingredients, and the main thing is to choose a brand that you can trust.

The methods for choosing lutein are:

1. The existence pattern of lutein.

There are two common types of lutein: "free" and "esterified". The latter is often referred to as "lutein ester", which needs to be converted into lutein in the human body to be absorbed by the body, and its stability and absorption utilization rate are better than lutein. The ingredients are more stable and easier to be absorbed by the body.

Therefore, when choosing lutein products, it is better to choose lutein esters.

2. The content of lutein.

It is certainly no problem for the human body to supplement lutein every day for eye protection, but if it is supplemented excessively every day, it will bring unnecessary burden to the body. According to research, about 12mg of lutein per day can meet daily needs.

3. The presence of lutein dosage form.

There are many lutein products, and the choice of dosage forms is also diverse, such as capsules, tablets, powder forms and other ways of existence. However, powders are currently the safest and most easily absorbed dosage form by the body.

4. According to age group.

Children under the age of 4 should not ingest lutein directly because it can cause jaundice in the child. Lutein supplementation for children aged 4-18 must be synthesized and converted in the child's body under the action of zinc, so it must be selected to contain zinc at the same time. Adults can directly consume lutein.

To sum up, Leeye lutein is developed according to different age groups, which is suitable for the needs of different groups of people for lutein.

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.

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.

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.
