Description

Neoxanthin is a naturally occurring xanthophyll carotenoid, a vital plant pigment involved in light harvesting and photoprotection. Its significance extends to human health as a key dietary precursor to the signaling molecule abscisic acid, which is linked to metabolic and inflammatory regulation. This compound is essential for manufacturers in the nutraceutical, food & beverage, and cosmetic industries seeking natural, bioactive ingredients for functional products.

Application

• Nutraceutical & Dietary Supplements: Used as a key ingredient in formulations targeting metabolic health, anti-inflammatory support, and overall antioxidant protection.
• Functional Food & Beverage Fortification: Incorporated into health drinks, yogurts, and snack bars to enhance nutritional value and provide natural color.
• Cosmetic & Personal Care: Valued in anti-aging and skin care products for its antioxidant properties, helping to protect skin from oxidative stress.
• Pharmaceutical Research: Serves as a reference standard and an active pharmaceutical ingredient (API) intermediate in metabolic and ophthalmological research.
• Animal Feed & Aquaculture: Added to feed to improve the coloration and health of poultry, fish, and crustaceans.
• Natural Colorant: Provides a stable yellow to orange hue in various food and cosmetic applications as a natural alternative to synthetic dyes.

Quality Control

Our Neoxanthin is produced and tested under strict quality management systems. Each batch is analyzed to ensure it meets high-purity standards suitable for food, nutraceutical, and research applications. A comprehensive Certificate of Analysis (COA), detailing parameters such as purity, identity, and heavy metals, is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store unopened vials at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. For daily use, keep the sealed container at 2-8°C. This product is easily oxidized and light-sensitive; prolonged exposure to air, heat, or light should be avoided.
