How long does lutein last to see the effect

The eye is the most important sensory organ of human being.

And when you stay up late at work, turn off the lights and play on your phone… With all the eye destruction,

There’s a substance in the eye that has a protective mechanism: lutein

¿Qué es la luteína?

Lutein is a carotenoid that is the main pigment in the retina of the human eye.

It focuses on the area of our eyes where vision is most acute, the macula region of the retina.

What does lutein do?

Filtered blue light

Luteína absorbs blue light, which is close to ultraviolet light, and can help reduce the damage caused by harmful blue light in the environment.

antioxidant

The strong antioxidant effect of lutein can help remove free radicals and protect the retinal nerve cells and macular area.

Reduces the risk of macular degeneration

Studies have shown that people who consume more lutein in their diet can reduce their risk of developing age-related macular degeneration (AMD), and taking lutein supplements for up to 12 months can improve some symptoms of AMD.

Reduce el riesgo de cataratas

Studies have shown that eating more lutein may reduce the risk of developing cataracts, and in addition, earlier studies have shown that taking lutein three times a week for up to two years can improve vision in older adults with cataracts.

How long does luteína eat have effect?

All nutrients into the body, there must be a digestion, absorption to the effective process.

Lutein is no exception, from taking to absorption, and then to effect, it certainly needs a process, generally about 2-4 months.

Because lutein supplementation needs to be absorbed through the gastrointestinal tract, through the chylous canal into the liver, the liver detoxifies and binds to the high-density protein (HDL) in the blood, and is transported to the macular area of the eye, the retina and the lens with the blood.

Therefore, the lutein absorbed into the blood has to circulate through almost all tissues of the body to reach the eye, which is a very slow process.

After taking it, it usually takes two weeks to detect an increase in lutein concentration in the blood and two months to detect an increase in lutein concentration in the eyes.

Depending on your lutein needs,

And the difference in intake,

The time to effect is also different.

In the human trial function test of alleviating visual fatigue, it was shown that:

After taking 1 tablet (10mg) of lutein once a day for 30 days, the symptoms of blurred vision, dry eyes, eye distention, eye pain and photophobia were improved.

Experiments on lutein supplementation in people with long-term light exposure to the eyes (such as people engaged in electric welding work) show that:

Lutein is taken orally 20mg daily for 12 weeks (approximately 3 months). The supplementation of lutein can significantly increase the macular pigment density and protect the visual function of these people. It is especially reflected in the protection of contrast sensitivity and glare sensitivity in dim environments

Although lutein is naturally present in our bodies, our bodies cannot synthesize lutein themselves and can only obtain it through diet.

The “Scientific Research Report on the Dietary Guidelines for Chinese Residents” (2021) pointed out that for dark vegetables rich in lutein, people eat only about 30% of the daily recommended total amount of vegetables, far less than the recommended level of more than 50%.

How to choose lutein?

Lutein is now on the market purified, made into capsules or chewable tablets, and ingested in this way is more direct. However, the key is to ensure quality.

In the choice of lutein supplement products, I also give you some tips:

1. Choose products from brands with food safety certification;

2. As a supplement for eye nutrition, the higher the content of lutein, the better the effect, the choice of products is to compare the content.

3. Clinically proven and patented lutein products are more trustworthy.
