Retinal health is important for maintaining good vision, and there is growing evidence that lutein, zeaxanthin, and mesozeaxanthin can play a role in protecting and preserving retinal health. Lutein and zeaxanthin are carotenoids, which are pigments commonly found in fruits and vegetables. In the eyes, these carotenoids accumulate in the macula, a part of the retina which is responsible for central vision. Research suggests that lutein and zeaxanthin can filter blue light and protect the macula from damage caused by ultraviolet light.
Mesozeaxanthin is another carotenoid found in the retina, and it's thought to play a role in preventing and reducing age-related macular degeneration (AMD). Studies have shown that mesozeaxanthin accumulates in the macula, and that it can help protect the retina from light-induced damage. It may also play a role in preserving vision in people with AMD. Recent studies from 2021 and 2022 have continued to support the role of lutein, zeaxanthin, and mesozeaxanthin in retinal health. A 2021 study published in the journal Nutrition Research used animal models to assess the effects of lutein and zeaxanthin supplementation on retinal health. The study found that lutein and zeaxanthin supplementation was associated with increased retinal health and reduced damage from oxidative stress.
Another study, which was published in the journal Ophthalmology in 2022, examined the effects of mesozeaxanthin supplementation in people with AMD. This study found that mesozeaxanthin supplementation was associated with improved retinal health and reduced AMD-related damage. One study on the role of lutein and zeaxanthin in retinal health was published in the journal Ophthalmology in 2018. The study assessed the levels of lutein, zeaxanthin and mesozeaxanthin in participants with and without AMD, and found that those with higher levels of these carotenoids had lower levels of AMD-related damage. Previously a study w published in the journal Nutrition in 2016, examined the relationship between lutein and zeaxanthin intake and the risk of developing AMD. The study found that people with a higher intake of these carotenoids were less likely to develop AMD, even after adjusting for other factors such as age and smoking status. Overall, lutein, zeaxanthin, and mesozeaxanthin are important carotenoids that can help to protect and preserve retinal health. Eating a healthy, balanced diet with plenty of fruits and vegetables is the best way to ensure that you're getting enough of these carotenoids. Supplements may also be beneficial, but it's best to talk to your doctor or healthcare provider before taking any supplements. References:
