What does the science actually say about eye vitamins?
In this video, I share the upfront truth: while many supplements are marketed for “eye health,” some of the strongest research supports the use of macular carotenoids — specifically lutein, zeaxanthin, and meso-zeaxanthin.
These carotenoids help increase macular pigment, which plays an important role in protecting the retina and supporting visual function. Higher macular pigment has been associated with a lower risk of aging eye diseases, as well as improvements in visual performance such as contrast sensitivity, glare recovery, and photostress recovery.
You can get lutein and zeaxanthin naturally from foods like green leafy vegetables, corn, and egg yolks. But research suggests many people do not get enough through diet alone. And since I do not eat perfectly every day either, I personally choose to supplement so I know I am consistently getting the amounts shown in research to be beneficial.
I have been sharing this science for years, and people often ask which product I personally use and trust. The brand I use is MacuHealth. youtube.com/@MacuHealth

As always, supplements are not a replacement for a healthy diet or routine eye care. Talk with your own eye doctor or healthcare professional if you have specific eye health concerns.
