Lutein and zeaxanthin

Lutein and zeaxanthin in the macula

What is the functionality of lutein and zeaxanthin?

As an antioxidant, lutein suppresses "reactive oxygen species" that cause eye aging, absorbs harmful light, and protects the eyes.

Lutein and zeaxanthin are abundant in the macula and lens of the eye, and their deficiency can lead to macular degeneration, cataracts, and other eye aging problems.


Lutein and zeaxanthin began to increase in lutein blood concentration and functionality approximately 2 weeks after intake began.

After 3 to 12 months of repeated administration, an increase in macular pigment density was observed, and the risk of developing macular degeneration was dramatically reduced in the group with high macular pigment density.
