Zeaxanthin is found in many vegetables, edible fish, and shrimp. The human body cannot synthesize zeaxanthin on its own and must obtain it through food or supplements.
Lutein and zeaxanthin are both carotenoids that are found in the macula of the retina of the eye.
Among the many eye protection ingredients, in addition to lutein (lutein esters), zeaxanthin also plays a key role in human eye health. "According to a recent study, children who supplement lutein + zeaxanthin daily for 40 consecutive days can increase macular pigment concentration and better protect vision.
