Description

Lutein Epoxide is a naturally occurring xanthophyll carotenoid, structurally related to lutein, and is a key intermediate in the plant carotenoid biosynthetic pathway. Its significance lies in its potent antioxidant properties and its role as a precursor to other bioactive compounds, making it a valuable ingredient for advanced nutraceutical and cosmeceutical formulations. This high-purity compound is essential for manufacturers and R&D teams in the dietary supplement, functional food, and pharmaceutical industries seeking to develop products focused on eye health, skin protection, and oxidative stress management.

Application

• Nutraceutical Ingredients: A premium active component in high-end dietary supplements targeting macular health and visual function.
• Functional Food & Beverage Fortification: Used to enhance the nutritional profile of health-focused foods and drinks with antioxidant benefits.
• Cosmeceutical Formulations: Incorporated into anti-aging skincare products for its protective effects against blue light and environmental oxidative damage.
• Pharmaceutical Intermediates: Serves as a critical starting material or reference standard in the synthesis and research of ophthalmic drugs.
• Animal Nutrition: Added to feed for poultry and aquaculture to improve pigmentation and animal health.
• Analytical & Research Standards: Used as a high-purity reference compound in HPLC, LC-MS, and other analytical methods for quality control and metabolic studies.

Quality Control

Our Lutein Epoxide is manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for identity, purity, and potency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay by HPLC, heavy metals, and residual solvents. Our quality commitment supports compliance with relevant standards for nutraceutical and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C to minimize oxidation and ensure long-term stability. Keep the container in a cool, dry, and well-ventilated area, separate from incompatible materials.
