Zeaxanthin, a carotenoid xanthophyll found in corn, primarily supports eye health by filtering harmful blue light and reducing the risk of age-related macular degeneration (AMD). It functions as a potent anti-inflammatory by inhibiting NF-κB p65 phosphorylation and as an antioxidant by neutralizing reactive oxygen species, protecting against cellular damage.
Reported Benefits (Provisional)
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.
Research Narrative (Provisional)
Clinically validated for its role in visual performance, AMD prevention, and oxidative stress reduction. Research supports additional benefits in cognitive and skin health.
Preparation & Dosage

Nutritional Profile
- Carotenoid: Zeaxanthin, a xanthophyll carotenoid, is the primary bioactive compound. - Antioxidant: Functions as a powerful antioxidant, neutralizing reactive oxygen species. - Photoprotective Pigment: Accumulates in the macula of the eye, filtering harmful blue light. - Lipophilic Compound: Its fat-soluble nature allows for integration into cell membranes, providing direct cellular protection.
Reported Mechanism (Provisional)
Zeaxanthin exerts its effects through potent anti-inflammatory and antioxidant mechanisms. It suppresses inflammatory cytokine production (IL-6, IL-8, MCP-1) and adhesion molecule expression by inhibiting the phosphorylation of NF-κB p65, a crucial upstream regulator of inflammatory responses. Additionally, it acts as a powerful antioxidant by neutralizing various reactive oxygen species, including singlet oxygen, hydroxyl radicals, and superoxide anions, thereby protecting against cellular damage like lipid peroxidation and DNA damage.
Clinical Narrative (Provisional)
Clinical studies have extensively validated zeaxanthin's efficacy in enhancing visual performance and reducing the risk of age-related macular degeneration (AMD) and cataracts. These investigations, often involving randomized controlled trials, demonstrate its ability to filter harmful blue light and improve contrast sensitivity. Furthermore, research supports its role in mitigating oxidative stress and suggests potential benefits for cognitive function and skin health, highlighting its broad systemic protective effects.
