Study:
This is a study supporting the use of Lutein in eye disease. From that study: “Lutein is one of the few xanthophyll carotenoids that is present in high concentration in the macula of human retina. As de novo synthesis of lutein within the human body is impossible, lutein can only be obtained from diet. It is a natural substance abundant in egg yolk and dark green leafy vegetables. Many basic and clinical studies have reported lutein’s anti-oxidative and anti-inflammatory properties in the eye, suggesting its beneficial effects on protection and alleviation of ocular diseases such as age-related macular degeneration, diabetic retinopathy, retinopathy of prematurity, myopia, and cataract.
Most importantly, lutein is categorized as Generally Regarded as Safe (GRAS), posing minimal side-effects upon long term consumption. In this review, we will discuss the chemical structure and properties of lutein as well as its application and safety as a nutritional supplement. Finally, the effects of lutein consumption on the aforementioned eye diseases will be reviewed. Most animal and clinical studies have provided promising results, supporting lutein’s efficacy in delaying development and progression of these conditions. At the same time, more evidence has emerged to demonstrate lutein’s possible role in alleviating outcomes of other eye diseases including ROP, myopia, and cataract.”
