Zeaxanthin is a carotenoid, a type of pigment found in various fruits and vegetables, particularly in leafy greens like spinach and kale. It plays a crucial role in protecting the eyes from harmful light and oxidative stress, contributing to overall eye health. This compound is often found alongside another carotenoid called lutein, and both are known to accumulate in the retina. Research suggests that zeaxanthin may help reduce the risk of age-related macular degeneration (AMD) and improve visual performance, making it an important nutrient for maintaining good eyesight.
