Lutein and zeaxanthin are free radical scavenging carotenoids that are preferentially deposited in the macula, a specialized area of the eye that is responsible for central vision.* Acting as primary filters of high-energy blue light, lutein and zeaxanthin help to promote normal visual health by neutralizing free radicals formed by light exposure, which is critical for normal recovery from bright light exposure and the maintenance of healthy contrast sensitivity.* Lutein and zeaxanthin are also found in neural tissues, including the brain, where they can support normal cognitive function, maintain a positive mood, and optimize the stress response.* These carotenoids may also play a role in optimizing sleep quality by minimizing sleep latency and arousal during the night
