Our high-quality cholecalciferol powder is produced in a cGMP-certified factory, strictly adhering to all FDA and EMA regulations, with a purity exceeding 99%. Whether you are producing therapeutic products, over-the-counter (OTC) supplements, or prescription drugs, our bulk vitamin D3 powder provides the stability and reliability you need for production, meeting the requirements of global regulatory agencies.

Vitamin D3 bulk powder is a microencapsulated, cold-water dispersed cholecalciferol with a standardized content ≥100,000 IU/g. Shaanxi Hongda's vitamin D3 pure powder utilizes a core "spray-drying microencapsulation" technology, encapsulating high-purity cholecalciferol in a patented water-soluble matrix, forming microcapsules with an extremely narrow particle size distribution.

Our powder exhibits excellent stability, low odor, and promotes bone resorption, supplementing the body's calcium needs.
