What is the difference between lutein & zeaxanthin? Lutein and zeaxanthin are known as isomers. While lutein and zeaxanthin are both found in the eye, lutein is more prominent at the edges of the retina and in the rods of the eye, and zeaxanthin is found primarily in the centre of the retina.
How do you maximize lutein?
Foods With Lutein. Lutein is in most fruits and vegetables, but green and yellow foods have the highest amounts. Because it’s a fat-soluble nutrient, cooking or eating lutein-rich foods with a healthy fat like olive oil can improve its absorption in your body.

What is the best time to take lutein?
Lutein supplements are available in soft-gel capsule form. They should be taken at mealtime because lutein is absorbed better when ingested with a small amount of fat, such as olive oil. The recommended dosage is 6 mg to 30 mg daily.
