What is lutein ester?

Lutein ester is a carotenoid fatty acid ester, chemically called lutein palmitate, which is easily soluble in organic solvents. It is widely found in plants such as corn, cabbage, and marigolds, especially in marigolds. Lutein ester is the main component of the retina and macula of the human eye. It has powerful anti-oxidant raw material and can prevent free radical oxidative damage to the eye, improve eye microcirculation, prevent senile cataracts, protect the retina, and prevent optic atrophy.

What are the effects?

1. Protect the retina: As the main pigment component of the macular area, lutein esters can effectively filter blue light, reduce the damage of blue light to the retina, prevent macular degeneration, and maintain clear vision.
2. Anti-oxidant raw material: Lutein esters have strong antioxidant capacity, can neutralize free radicals, reduce eye oxidative stress, protect eye cells from damage, and delay eye aging.
3. Relieve visual fatigue: Long-term exposure to electronic screens or reading can easily lead to dry and tired eyes. Lutein esters can enhance eye blood circulation, promote tear secretion, effectively relieve visual fatigue, and improve visual comfort.
4. Promote visual development: For children and adolescents, lutein esters are an indispensable nutrient for visual development. It can promote the normal growth and differentiation of retinal cells, and help prevent myopia, amblyopia and other vision problems.
5. Enhance immunity: Lutein esters can also enhance the body's resistance to eye infections and reduce the occurrence of eye inflammation by regulating the immune system.

What are the applications?

1. Eye care products: Lutein esters are added to eye care products such as eye drops, eye masks, eye creams, etc., acting directly on the eyes to provide a quick and effective eye protection experience.
2. Food additives: It can be used as a food colorant in frozen drinks, baked foods, instant rice and flour products, beverages and other fields.
3. Feed colorant: It is also used as a natural colorant in feed for the coloring of poultry eggs, salmon, trout and shrimp.
4. Pharmaceutical raw materials: It can also be used as pharmaceutical chemicals, mainly for eye diseases such as myopia, amblyopia, hyperopia, presbyopia, cataracts, etc.
