1. The efficacy and role of lutein
Increase macular pigment density
Lutein is an important component of the macular pigment in the human eye. The density of macular pigment is low, which can damage the retinal pigment epithelium and cause macular degeneration. Supplementing lutein can effectively increase the density of macular pigment, protect the macula, promote the development of the macula, and prevent the lack of this nutrient from causing lesions in the macular area of the retina, resulting in vision loss, dark shadows in front of the eyes, or distortion of vision, etc.
Protect eyes from blue light damage
Electronic product screens emit harmful blue light, which can penetrate the eyeball directly to the retina and macular area, causing macular damage and easily leading to macular degeneration. Supplementing lutein can absorb a large amount of harmful high-energy blue light and form a "blue light filter" to protect the macular area and retina from light damage.
Remove harmful free radicals from the eyes
Ultraviolet rays in sunlight enter the eyes and produce a large number of free radicals that attack the eyes and cause macular degeneration. Lutein has strong antioxidant activity and is equivalent to a powerful antioxidant. It can scavenge free radical substances harmful to the eyes and reduce the oxidative damage caused by free radicals to macular cells, thereby protecting the eyes.
To sum up, the efficacy and role of lutein is to increase macular pigment density, protect the eyes from blue light damage and remove harmful free radicals in the eyes, which is of great significance to protecting eye health.
2.Taboos on lutein consumption
Take after meals: The effect is better when taken after breakfast. The intestines are active during the day. At this time, lutein is supplemented and the absorption rate is relatively high. Try not to take it before going to bed, because the body's metabolism slows down at this time, which will reduce absorption.
Pay attention to the water temperature: Lutein itself has certain activity, but its stability is poor. It is easily affected by high temperatures and causes inactivation, and cannot have any effect on the human body. Therefore, when supplementing lutein, you cannot use hot water that is too hot. It is recommended to use warm boiled water.
