Zeaxanthin is a yellow-orange carotenoid pigment found in fruits and vegetables such as peppers, corn and oranges. Zeaxanthin may be more important than lutein in protecting the ocular tissue from oxidative damage.
- Zeaxanthin is the primary pigment found in the center of the macula.
- The human macula preferentially accumulates zeaxanthin over lutein at a rate of 2.4 times more zeaxanthin than lutein.
- Zeaxanthin is selectively deposited at the center of the macula where protection from oxidation is most critical.
- Zeaxanthin is found in blood serum at a 1:4 ratio of zeaxanthin to lutein.
