Sources of Lutein & Zeaxanthin

Lutein and zeaxanthin are present together in a variety of fruits and vegetables: dark green leafy vegetables like spinach and kale are particularly rich sources of lutein and zeaxanthin (47). That lutein and zeaxanthin are found together in green leafy vegetables is actually not surprising considering the role of lutein and zeaxanthin in photosynthesis. Although poultry do not themselves make carotenoids, lutein and zeaxanthin accumulate in the egg yolk, which depends upon diet (48).

Most available lutein and zeaxanthin supplements have much higher amounts of lutein than zeaxanthin. Such supplements typically contain 4–20 mg lutein and 0.2–1 mg zeaxanthin, although other dosages are available.
