Meso-Zeaxanthin
The most potent macular carotenoid, located at the very center of the macula for maximum protection.
Also known as: 3R,3'S-zeaxanthin
Overview
Meso-zeaxanthin is one of the three main carotenoids found in the macula, alongside lutein and regular zeaxanthin. It is the most powerful antioxidant of the three and is concentrated in the epicentre of the macula, where the need for protection is greatest. While some meso-zeaxanthin can be created in the retina from lutein, dietary intake or supplementation is crucial for maintaining optimal levels.
Key Benefits
Strengthens Central Macula
Specifically increases macular pigment optical density (MPOD) at the center of the macula, the area responsible for sharp, detailed vision.
Potent Blue Light Filtering
Is a more powerful blue light filter than lutein or zeaxanthin, offering superior protection for the fovea.
Completes the Carotenoid Shield
Works synergistically with lutein and zeaxanthin to provide a complete and robust protective layer of macular pigment.
Dosage & How to Take
Most research uses a formula containing 10 mg of meso-zeaxanthin, 10 mg of lutein, and 2 mg of zeaxanthin (10:10:2 ratio).
