Lutein is a natural yellow-orange pigment produced exclusively by plants. The human body alone cannot produce lutein, therefore it must be supplied with food. Lutein is transported through blood to the liver. Then from the liver it is transported to tissues depending on the demand and its role in the tissues. Most lutein accumulates in the eyeball, specifically in the lens and in the macula of retina.
Lutein together with zeaxanthin accumulated in the lens and retina, counteracts harmful UV radiation. It filters blue light and can protect the yellow spot against free radical damage. A healthy spot enables proper central vision. Lutein has a positive effect on visual acuity and prevents serious eye diseases.Lutein accumulates not only in the eye tissue but also in other tissues, e.g. in the skin tissue. Lutein affects the elasticity of the skin and improves hydration of its tissues. In addition, it normalizes the work of the sebaceous glands and contributes to the increase of the lipid layer of epidermis.Lutein is also an important nutrient that positively affects the cardiovascular system.
