Description

Vitamin D3 Octanoate is a lipophilic ester derivative of cholecalciferol (Vitamin D3), designed for enhanced stability and bioavailability. This compound is critical for formulating advanced nutritional supplements and pharmaceutical preparations where precise fat-soluble vitamin delivery is required. It is primarily utilized by manufacturers in the nutraceutical, pharmaceutical, and advanced food fortification industries seeking a stable and efficacious form of Vitamin D.

Application

• Dietary Supplements & Nutraceuticals: As a key active ingredient in high-potency softgel capsules, liquid drops, and multivitamin formulations for Vitamin D3 supplementation.
• Pharmaceutical Formulations: Used in prescription and over-the-counter medications for treating and preventing Vitamin D deficiency and related bone disorders.
• Functional Food & Beverage Fortification: Incorporated into dairy products, plant-based milk alternatives, juices, and baked goods to enhance nutritional value.
• Cosmetic & Personal Care: Employed in specialized skincare products for its role in supporting skin health and cellular functions.
• Animal Nutrition (Feed Premixes): Used in poultry, swine, and aquaculture feed to ensure proper bone development, calcium homeostasis, and overall animal health.
• Research & Development: Serves as a standard or intermediate in biochemical research and the development of new therapeutic agents.
