The Effects and Effects of Marigold Extract Zeaxanthin

Zeaxanthin is An Important Component of Macular Pigment in The Eyes

Zeaxanthin (Z) and lutein (L) are isomers and are important carotenoids in the diet. After ingestion by the human body, they are distributed in different tissues and organs, and selectively in the retina of the eye. It is highly deposited in the macular area and together with racemic zeaxanthin (MZ) constitutes the macular pigment in the macular area of ​​the retina. Macular pigment plays an important role in filtering harmful blue light, scavenging free radicals, and interrupting lipid peroxidation, and can reduce the damage to the eyes caused by the above factors. Therefore, one of the functions of zeaxanthin is to maintain the normal and complete structure of macular pigment, which can Maintains healthy visual function and reduces the risk of age-related eye diseases.

Zeaxanthin and lutein Complement Each Other and Absorb Blue Light More Comprehensively

With the popularity of smartphones, the frequency and extent of eye exposure to blue light are increasing. Studies have proven that carotenoids with conjugated polyene chains can absorb visible light, while macular pigments, whose main components are zeaxanthin and lutein, can absorb 40-90% of blue light. The maximum absorption peak of zeaxanthin in ethanol solution is 451nm, and the maximum absorption peak of lutein in ethanol solution is 445nm. It can be seen that the second effect of zeaxanthin is to absorb blue light with longer wavelength, while lutein can absorb longer wavelength. Short blue light, the combination of the two can better absorb blue light.

Able to Better Quench Singlet Oxygen

The third function of zeaxanthin is antioxidant. The molecular structure of zeaxanthin makes it have strong antioxidant activity. By evaluating several carotenoids contained in macular pigment, the researchers found that zeaxanthin is better at quenching singlet oxygen.

Protect Visual Cells and Maintain Normal Visual Functions

Visual health is not only about seeing objects clearly, but also about being able to see various colors clearly. There are cones and rods on the retina. The cones are responsible for photopic vision and color vision. They are mainly distributed in the macular area. There are only cones in the concave center of the macula. When there is a problem with the cones, we may not be able to Recognize colors normally. Research data shows that the concentration of zeaxanthin in the fovea of ​​the macula is 500-1000 times higher than its concentration in plasma. It can be seen that in addition to being one of the components of macular pigment, the effect of zeaxanthin is also reflected in the visual protection of the eyes. .
