Description

Zeaxanthin is a vital, naturally occurring xanthophyll carotenoid prized for its potent antioxidant properties and vibrant yellow to red pigmentation. This compound is essential for applications demanding high-purity, stable colorants and bioactive ingredients that support human and animal health. It is a critical raw material for manufacturers in the nutraceutical, food & beverage, cosmetic, and animal feed industries seeking to enhance product value and efficacy.

Application

• Dietary Supplements & Nutraceuticals: A key ingredient in eye health formulas and antioxidant blends, supporting macular pigment density and visual function.
• Food & Beverage Fortification: Used as a natural colorant (E161h) and functional nutrient in beverages, dairy products, confectionery, and baked goods.
• Cosmetics & Personal Care: Incorporated into skincare serums and creams for its antioxidant benefits, helping to protect skin from environmental oxidative stress.
• Animal Nutrition (Feed Additives): Added to poultry feed to enhance yolk color in eggs and to aquaculture feed for salmon and trout flesh pigmentation.
• Pharmaceutical Intermediates: Serves as a starting material or intermediate in the synthesis of specialized pharmaceutical compounds.
• Clinical Research & Biomarkers: Utilized as a standard or reagent in biochemical research and studies related to carotenoid metabolism.
