Description

Pterostilbene is a naturally occurring stilbenoid compound, structurally related to resveratrol but with superior bioavailability and metabolic stability. This high-value ingredient is prized for its potent antioxidant and cellular health-supporting properties, making it a critical component in advanced formulations. It is primarily sought by manufacturers in the nutraceutical, pharmaceutical, and cosmetic industries for developing premium health supplements and functional products.

Application

• Nutraceutical & Dietary Supplements: A key active ingredient in capsules, tablets, and powders targeting antioxidant support, healthy aging, and metabolic wellness.
• Pharmaceutical Intermediates: Serves as a starting material or intermediate for the research and synthesis of novel therapeutic agents.
• Cosmetic & Personal Care: Incorporated into anti-aging serums, creams, and lotions for its skin-protective and rejuvenating benefits.
• Functional Food & Beverages: Used to fortify health drinks, nutritional bars, and other food products with enhanced bioactive content.
• Research & Development: Utilized in biochemical and pharmacological studies investigating stilbenoid mechanisms and health effects.
• Animal Nutrition: Applied in premium feed additives for pets and livestock to promote overall health and vitality.

Quality Control

Our Pterostilbene is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, UV), to ensure it meets stringent specifications for high-grade applications. Certificates of Analysis (COA) documenting full test results are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). As the material is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat and incompatible materials.
