Benefits of Marigold Extract Lutein 

Marigold Extract Lutein is natural yellow pigment, can be used food additives as colorant.
Marigold Extract Lutein can supply retina of the eye protect against UV rays and AMD prevention.
Marigold Extract Lutein is a natural anti-oxidant and carotenoids as a good nutrient for human health.
Marigold Extract Lutein can be used as feed additive for poultry and aquaculture.

The specific performance is as follows:

lutein from marigold Protect The Retina and Ensure Clear Vision

The retina is a thin film inside the eyeball that receives light and converts it into nerve signals that are sent to the brain to form vision.
There are special cells in the retina called cones, which are responsible for central vision and color vision. Cone cells are concentrated in a small area at the back of the eye called the macula.
The macula is the most important part for us to see objects clearly.
Lutein  marigold is found in the macula and absorbs harmful blue light, preventing it from damaging the retina and cone cells.
Blue light is a type of light with shorter wavelength and higher energy that can penetrate the cornea and lens and reach directly to the retina.
If you are exposed to too much blue light for a long time, such as using an electronic screen, it will cause inflammation, oxidation and degeneration of the retina, causing vision loss, dry eyes, eye fatigue and other problems.
Lutein marigoldacts as a natural light filter, filtering out excess blue light and protecting the retina and cone cells. Lutein also acts as an antioxidant, scavenging free radicals and preventing retinal aging.
Therefore, lutein protects our retinas and ensures clear vision.

lutein from marigold Improve Eyesight

In addition to protecting the retina, lutein can also improve our vision.
Lutein marigold can improve our adaptability to light, increase our sensitivity to contrast and color, and enhance our night vision and peripheral vision.
Lutein marigold can help us quickly adjust our eyes in environments of different brightness, reducing glare and dark adaptation time.
This allows us to see clearly in strong light or dim conditions.
Lutein marigold can also improve our ability to distinguish the edges and contours of objects, and increase our ability to distinguish colors and brightness. This allows us to see more detail and color.
Lutein marigold also enhances our night vision and low-light vision.
This is because lutein promotes cooperation between cones and rods. Rod cells are another type of cell found in the retina, and they are primarily responsible for dark light and peripheral vision.
Lutein marigold allows cone cells and rod cells to work better in coordination, improving our visual acuity and reaction speed in the dark.
Therefore, lutein can improve our vision, allowing us to see more clearly, more accurately, and faster.

lutein from marigold Prevent Glaucoma

Glaucoma is a common ophthalmic disease, its main characteristic is an increase in intraocular pressure, leading to damage to the optic nerve, resulting in visual field defects and vision loss.
If left untreated, glaucoma can lead to blindness. The occurrence of glaucoma is related to factors such as genetics, age, high blood pressure, and diabetes.
Lutein can prevent the occurrence and development of glaucoma because lutein can reduce intraocular pressure, protect the optic nerve, and improve blood circulation.
Lutein can reduce intraocular pressure by inhibiting the activity of carbonic anhydrase and reducing the secretion of aqueous humor.
Aqueous humor is a fluid found in the front of the eye that maintains its shape and pressure.
If the aqueous humor is secreted too much or is not discharged smoothly, it will cause the intraocular pressure to increase and compress the optic nerve.
Lutein can also protect the optic nerve from damage by free radicals and inflammatory factors through antioxidant and anti-inflammatory effects. The optic nerve is a nerve fiber that connects the eye to the brain and carries visual signals.
If the optic nerve is damaged, visual function will be affected.
Lutein can also increase blood flow and oxygen supply to eye tissues by improving blood circulation.
This can promote the metabolism and repair of eye tissue and prevent damage caused by ischemia and hypoxia.
Therefore, lutein can prevent the occurrence and development of glaucoma and protect our optic nerve and vision.


lutein from marigold Delay the Occurrence of Cataracts

Cataract is a common eye disease. Its main symptom is that the lens becomes cloudy and opaque, which affects the focus of light, leading to blurred vision, pale colors, reduced contrast and other problems.
If cataracts seriously affect your quality of life, surgery may be needed to replace the intraocular lens. The occurrence of cataracts is related to aging, ultraviolet rays, diabetes, smoking and other factors.
Lutein can delay the occurrence and progression of cataracts because it protects the crystalline lens from damage by ultraviolet rays and free radicals.
Lutein can absorb the blue part of ultraviolet light and prevent it from penetrating into the crystal.
Lutein can also scavenge free radicals in crystals through its antioxidant effect, preventing them from damaging the structure and transparency of crystals.
Free radicals are unstable molecules that can cause oxidative stress in the crystal, causing proteins in the crystal to denature and aggregate, forming cloudy spots or flakes.
Therefore, lutein can delay the occurrence and progression of cataracts and protect our lenses and vision.

lutein from marigold Prevent the Sequelae of High Myopia

High myopia refers to a condition in which the myopia degree exceeds 600 degrees or the spherical equivalent exceeds 800 degrees.
The main characteristic of high myopia is that the anterior and posterior axis of the eyeball is too long, resulting in thinning, weakening, and degeneration of the eyeball wall, choroid, and retina, and the corresponding fundus blood vessels become more slender and fragile.
These changes will increase the risk of some fundus diseases, such as floaters, macular hemorrhage, retinal detachment, etc. These lesions can seriously affect vision and even lead to blindness.
Lutein can prevent the sequelae of high myopia. This is because lutein can enhance the stability and elasticity of fundus tissue, prevent the axial length of the eyeball from continuing to increase, reduce the rupture and bleeding of fundus blood vessels, and protect the retina from traction and tearing.
Lutein can also promote the repair and regeneration of fundus tissues, increase the permeability and perfusion of fundus blood vessels, improve the nutrition and oxygen supply of fundus tissues, and prevent ischemia, hypoxia, and necrosis of fundus tissues.
Therefore, lutein can prevent the sequelae of high myopia and protect our fundus and vision.


Other effects of lutein from marigold

In addition to being good for the eyes, lutein also has some other effects, such as:

lutein from marigold Antioxidant

Marigold flower extract lutein is a powerful antioxidant that scavenges excess free radicals from the body and prevents them from causing oxidative damage to cells.
Free radicals are unstable molecules that can cause oxidative stress in the body, leading to cell aging, mutation, death and other problems.
Free radicals are associated with many chronic diseases, such as cardiovascular disease, neurodegenerative diseases, cancer, etc.
Lutein can protect us from free radicals, delay the aging process, enhance immunity, and prevent various chronic diseases.


Marigold flower extract lutein Anti-cancer Effect

Marigold flower extract lutein also has certain anti-cancer effects because lutein can regulate cell cycle, induce cancer cell apoptosis, inhibit cancer cell proliferation, metastasis, angiogenesis and other processes.
Lutein can also enhance the body’s tolerance to radiation and chemical drugs, and reduce the side effects of radiotherapy and chemotherapy.
Lutein has certain preventive and therapeutic effects on some common cancers, such as lung cancer, breast cancer, prostate cancer, colon cancer, etc.

Marigold lutein side effects:

In the known scientific literature, Marigold flower extract lutein is extremely safe when used in moderate doses, and no toxicity or adverse effects have been found with Lutein and zeaxanthin in a large-scale study of 10 mg daily over a five-year period.

The only confirmed side effect for the hands and feet skin yellowing (due to long-term large dose or overdose, also known as carotenemia), the cause of the body is more sensitive to Marigold flower extract lutein, metabolism is not enough to cause skin yellowing, do not know that it is jaundice

Carotenemia is harmless to the human body, as long as the intake is reduced, the phenomenon of skin yellowing will gradually fade, so do not worry too much.


Marigold flower extract lutein safety precautions (5 points of use taboo)


1. The safety of Marigold flower extract lutein use during pregnant women and lactation is unknown, so it is recommended to take more vegetables and fruits.

2. Cystic fibrosis patients are often unable to successfully absorb carotenoids in food or supplements, so pay attention when using Marigold flower extract lutein products.

3. Simultaneous consumption of snacks containing alternative oils or use of other carotenoid supplements may reduce lutein absorption.

4. In one case review, a woman with glaucoma who had been ingestion of Marigold flower extract lutein (20 mg daily for 8 years, combined with a high-lutein diet) developed a case of retinal crystal deposition, which did not affect the patient’s vision and partially disappeared after discontinuation.

5. Smokers taking high doses of Marigold flower extract lutein supplements (greater than 10 mg daily) may be associated with a higher risk of lung cancer, so caution should be exercised before use.
