2. What Is Zeaxanthin?
Zeaxanthin is a lipid-soluble carotenoid belonging to the xanthophyll family, commonly found in marigold flowers, corn, paprika, and leafy vegetables. It is structurally related to lutein and is widely researched as a diet-derived carotenoid concentrated in ocular tissues, particularly the macular region.
In ingredient applications, Zeaxanthin is valued for its chemical stability, compatibility with lipid-based systems, and antioxidant characteristics, making it suitable for capsules, softgels, beverages, and cosmetic formulations.
