Eating lutein is good for the eyes, who is the best partner of lutein? What do compound ingredients do

It is said that the most indispensable things for modern people are mobile phones and computers. They are by their side or at hand almost all the time. Whenever they have free time, they take them out and take a look. It almost becomes a subconscious action. , are playing on the phone.

However, with the use of digital products for a long time, the pressure on people’s eyes will increase. In order to protect the eyes, people have begun to pay attention to the health care of the eyes. At this time, the first choice is lutein, but lutein Products are rarely single products, and manufacturers always recommend various ratios, which makes people wonder how to choose, then, which ingredients are the best partners of lutein, if you want to know, don’t miss it today .

Understand the health benefits of lutein

The reason why lutein can protect the eyes is that lutein can accumulate in the lens and macula of the eyes, which can play an antioxidant and anti-blue light effect, and can also protect the optic nerve cells of the eyes and avoid damage. We all know that the human eye is like a camera, the crystal is the lens of the camera, the macula is the photographic film, and the function of lutein is to protect the clarity of the lens and prevent overexposure of the film, thereby preventing cataracts and preventing macular degeneration.

In addition, lutein can also protect human vision, such as reducing color chromatic aberration, improving contrast acuity, and improving the accommodation ability of eyesight. This situation may not be understood by everyone, but it will be clear with an example. For example, when driving at night, if you suddenly enter a tunnel or are flashed by strong light, your eyes will have a brief blurred vision, but lutein It can help people adjust this light change, enhance their ability, and avoid being in a state of being unable to see objects clearly for a long time, so as to avoid accidents, so it is also helpful for drivers to eat lutein.

However, we need to let everyone understand that although lutein has many functions, it also has limitations. For example, problems such as myopia and floaters cannot be effective. In order to treat myopia, taking lutein is a waste of money.

Lutein sold on the market is often added with a lot of formulas, and it is said that this combination is better for the eyes, so is the effect true? Take a look!

Added Zeaxanthin

Zeaxanthin is most commonly used in combination with lutein, although the difference between the two is not well understood. Zeaxanthin is actually an isomer of lutein, they are all carotenoids, they are the same in chemical formula, the only difference is the different position of the double bond in one end of the ring. But it is this difference that leads to different wavelengths of light that the two can absorb.

Lutein absorbs light with a wavelength of 430-450nm, and zeaxanthin absorbs blue-violet light with a wavelength between 400-500nm, thereby neutralizing a wide range of blue light, which means that the two cannot replace each other, but They can complement each other, so it makes sense for both to exist.

Is the golden ratio of 5:1 really good for the two?

Generally, in the advertising slogans we hear, the ratio of lutein to zeaxanthin is the golden ratio of 5:1. This ratio is actually a default ratio. The source is the data given by the relevant papers of the American Health Nutrition Survey. It is based on the daily intake of lutein and zeaxanthin in the American diet at that time, as well as the ratio of the two in human blood.

Therefore, this is a conventional ratio, and it does not say that it must be good or bad. When choosing, you can choose other ratios of lutein and zeaxanthin, not necessarily according to the compatibility of 5:1.

Add anthocyanins

Many lutein products may add anthocyanin, which is also a common health care product. Anthocyanin is a natural plant pigment that exists in most vegetables and fruits, such as blueberries. But anthocyanin is actually a general term for many plant pigments, not a component, so the types and concentrations of anthocyanins extracted from different fruits and vegetables are different.

Modern research believes that anthocyanins have strong antioxidant effects and can help the body to remove free radicals. Some anthocyanins have other auxiliary effects. The blood flow of blood vessels in the eyes helps the metabolism of the eyes and improves visual fatigue. Diabetic patients are prone to eye diseases. If such ingredients are added, it can play a certain protective role. Therefore, from the perspective of these effects, anthocyanins are helpful for eye fatigue, myopia, night vision, etc. However, these health care functions are currently not supported by strict clinical research, and the choice is also based on individual effects.

In addition, some products play word games, and the description says that certain fruits and vegetables have more extracts. This is different from the concentration of anthocyanin, and it is necessary to judge the purchase based on the concentration of anthocyanin.

However, some people say that some of the anthocyanins sold on the market may be artificial pigments, which can be easily judged because anthocyanins have different colors under different pH values, reddish under acidic conditions, and bluish under alkaline conditions. So, we can check in different acid-base solutions, if there is a change it is true, if there is no it is false.

Add Astaxanthin

At present, many recipes will emphasize the additional addition of astaxanthin.

Structurally, astaxanthin is also similar to lutein, so it can also function similar to lutein. The problem, however, is that astaxanthin cannot accumulate in the macula, and its effectiveness in preventing macular degeneration is limited. However, astaxanthin can effectively relieve visual fatigue, especially for children who use digital products for a long time. According to research, taking 4-6 mg of astaxanthin every day for a month can significantly improve eye fatigue.

In addition, in addition to anti-oxidation, astaxanthin can also improve eye accommodation, control eye inflammation, increase retinal capillary blood flow, and achieve the effect of eye health care. Cataracts etc. also help.

However, what everyone needs to understand is that any product needs an appropriate dose. This is the result of scientific research. If it is only added and the effective concentration is not reached, then it is equivalent to eating for nothing. The same is true for astaxanthin, so it is not a certain The more nutrients added to a product, the better. Although there are many, they are not enough. Then, it is lonely to eat every day. Everyone should look at the dosage when choosing the corresponding product.

added fish oil

When I was a child, my parents often told me that eating fish is good for the eyes. In fact, it mainly refers to the intake of DHA, which is the main component of fish oil. More than half of the retinal photoreceptor cell membrane is composed of Omega-3 DHA. Direct supplementation of DHA can maintain normal visual function and protect the optic nerve.

In addition, Omega-3 can reduce inflammatory irritation in the eyes, prevent water loss, and improve dry eye syndrome. And more importantly, the combination of fish oil and lutein can also promote the absorption of lutein, so this is the best partner of lutein.

However, if the lutein compound fish oil product, the content of fish oil is generally not too high, and it is also limited by the packaging, so it is best to buy the two separately and take them together.

Added hyaluronic acid

Hyaluronic acid, the name is too familiar, it is mostly used for medical beauty, but what is the use of adding hyaluronic acid to lutein products?

Hyaluronic acid has good moisturizing and lubricating properties, and this effect can also be used on the eyes. Studies have shown that hyaluronic acid eye drops can prolong the time of tear layer destruction, help corneal wound healing, and improve the discomfort of dry eyes. Oral administration is different. The dose required by oral administration may not reach the dose of eye drops at all, so it is difficult to judge the effect of adding hyaluronic acid to lutein, and there is no research to confirm it, so everyone maintain a wait-and-see attitude.

Then, the best partner of lutein will be revealed:

Different formulas of eye care products have different health care effects. For the compatibility of lutein, try to choose the formula of compound zeaxanthin, because the two absorb light with different wavelengths; if you want to improve eye fatigue, you can choose compound anthocyanin or The formula of astaxanthin; if you want to improve dry eyes and help the absorption of lutein, you can choose additional fish oil products to take together, which will have better results; as for hyaluronic acid, it is better to wait and see!
