Overview
Vitamin D3 500 CWS is a micro‑encapsulated, water‑dispersible beadlet form of Vitamin D3 (Cholecalciferol). Designed for feed premixes, liquid nutritional additives, and water-dispersible applications. Micro-encapsulation improves stability against oxidation, heat, and light. Water-dispersible properties allow easy incorporation into aqueous systems.
