Zeaxanthin is a carotenoid antioxidant that collects in the macula of your eye. It supports macular pigment density and shields retinal cells from oxidative stress.
People reach for zeaxanthin to keep vision sharp, especially as eyes get older. Your body cannot manufacture it, so food or supplements supply what you need.
Being fat-soluble, zeaxanthin absorbs better alongside a meal containing some fat. Eye health blends often combine it with lutein.
