Health Benefits
Supports eye health by filtering harmful blue light and reducing the risk of age-related macular degeneration (AMD) and cataracts.
Enhances visual performance by improving contrast sensitivity and reducing glare.
Provides antioxidant protection by neutralizing reactive oxygen species and limiting cellular oxidative damage.
Promotes cognitive health by reducing neuroinflammation and oxidative stress in brain tissue.
Improves skin resilience and photoprotection, reducing UV-induced aging and enhancing skin integrity.
Origin & History
Zeaxanthin is a key macular carotenoid extracted from *Zea mays* (yellow corn), a staple crop native to Mesoamerica and cultivated worldwide. This potent antioxidant contributes significantly to ocular, cognitive, and skin health through its powerful photoprotective and free-radical scavenging properties. It is a vital compound in functional nutrition for supporting visual acuity and systemic cellular defense.
“Traditionally consumed in maize-based diets throughout Central and South America, zeaxanthin-rich corn has contributed to visual resilience in populations with high sun exposure. This long-standing dietary intake highlights the historical recognition of corn's nutritional value, particularly for eye health in sun-drenched regions.”Traditional Medicine

Frequently Asked Questions
What is zeaxanthin?
Zeaxanthin is a powerful antioxidant known as a carotenoid, naturally found in corn and leafy greens. It accumulates in the retina of your eye to act as a natural filter against damaging blue light from screens and the sun.
How much zeaxanthin should I take for eye health?
Clinical studies, like the AREDS2 trial, support a daily intake of at least 2 mg, with many formulas providing 6-10 mg for optimal eye protection. Always take it with a meal that contains fat to ensure proper absorption.
What is the difference between lutein and zeaxanthin?
They are both vital eye antioxidants that work as a team. Zeaxanthin is more concentrated in the very center of the macula (responsible for sharp, central vision), while lutein is dominant in the surrounding areas. Taking both provides complete macular protection.
