Description

Zeaxanthin is a naturally occurring xanthophyll carotenoid, a powerful antioxidant known for its distinctive yellow to red pigmentation. It is a critical nutrient for eye health, specifically protecting the macula from blue light damage and oxidative stress. This high-purity ingredient is essential for manufacturers in the nutraceutical, food and beverage, and animal feed industries seeking to enhance the health profile and visual appeal of their products.

Application

• Dietary Supplements & Nutraceuticals: A key active ingredient in vision support formulas, antioxidant blends, and general wellness supplements.
• Food & Beverage Fortification: Used as a natural colorant and functional nutrient in health drinks, dairy products, and fortified foods.
• Cosmetics & Skincare: Incorporated into topical formulations for its antioxidant properties, helping to protect skin from environmental stressors.
• Animal Nutrition: Added to poultry feed to enhance yolk color in eggs and to aquaculture feed for salmon and trout pigmentation.
• Pharmaceutical Intermediates: Serves as a starting material or intermediate in the synthesis of specialized pharmaceutical compounds.
• Clinical Research: Used as a standard or reagent in studies focused on ophthalmology, antioxidant mechanisms, and carotenoid metabolism.
