Description

Antheraxanthin is a naturally occurring xanthophyll carotenoid, a vital intermediate in the plant-based violaxanthin cycle. This compound matters for its significant role as a photoprotective agent and antioxidant, helping to mitigate oxidative stress in biological systems. It is primarily needed by manufacturers in the nutraceutical, cosmetic, and food & beverage industries for formulating high-value, science-backed products.

Application

• Nutraceutical & Dietary Supplements: Used as a key active ingredient in antioxidant formulations and vision health supplements.
• Cosmetic & Personal Care: Incorporated into anti-aging serums and creams for its skin-protective and antioxidant properties.
• Functional Food & Beverage Fortification: Serves as a natural colorant and functional additive to enhance the nutritional profile of health foods and drinks.
• Aquaculture & Animal Feed: Applied in feed formulations to improve the coloration and health of farmed fish, shrimp, and poultry.
• Pharmaceutical Research: Utilized as a reference standard or intermediate in biochemical research and drug discovery related to oxidative stress.
• Agricultural Science: Studied for its role in plant stress physiology and as a potential biostimulant.
