Core Functions
Professional Eye Protection: Safeguards eyesight and prevents vision decline by protecting the yellow membrane of the retina, inhibiting macular degeneration and blurred vision caused by aging or external stimuli. It acts as a natural “blue light filter” for the eyes, absorbing a large amount of harmful blue light that enters the eyes and reducing retinal damage.
Powerful Antioxidation: Inhibits the formation of harmful free radicals in the body, neutralizes oxidative stress, protects cells from free radical damage, and delays the oxidative aging of tissues and organs.
Food Industry
As a 100% natural colorant, our lutein powder adds a bright, natural yellow hue to food products, enhancing the visual appeal and shine of goods. It is suitable for beverages, pastries, candies, dairy products and other food formulations, and is a safe alternative to synthetic colorants, complying with food safety regulations for natural additive use.
Health Product Industry
As a key eye-nourishing nutrient, lutein powder is the core raw material for eye health supplements. It replenishes essential nutrients for the eyes, effectively protects the retinal structure, and is ideal for formulating capsules, tablets, gummies and oral liquids targeting blue light protection and retinal health, catering to the needs of people who use electronic devices for a long time and middle-aged and elderly groups concerned about macular health.

Q: What is the quality standard of your lutein powder?
A: Our lutein powder strictly complies with the USP (United States Pharmacopeia) standard, with a fixed molecular weight of 568.87 and CAS number 127-40-2, ensuring high purity and stable product performance.
Q: How does lutein protect our eyes from blue light?
A: Lutein is a natural component that can absorb a large quantity of blue light entering the eyes. It accumulates in the retinal yellow membrane, acts as a physical and chemical filter for blue light, and reduces the damage of high-energy blue light to retinal cells, thus protecting eye health and preventing vision decline.
Q: Can lutein powder be used as a food colorant?
A: Yes. Lutein powder is an excellent natural yellow colorant in the food field. It can add a natural and bright shine to food products, and is a safe, healthy alternative to synthetic colorants for various food formulations.
