Description
The fine-granular particle-size format of Dry Vitamin D3 Powder, optimized for direct compression pharmaceutical tableting and premium dry-blend applications. Distinct from standard spray-dried powder by particle morphology and flow characteristics.
Pale yellow to brown free-flowing fine granular powder. Improved flow and reduced segregation in dry-blend manufacturing compared to standard spray-dried powder.
We supply food-grade and pharmaceutical-grade Dry Vitamin D3 Fine Granular from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production.
Common market grades include 100,000 IU/g Fine Granular, 500,000 IU/g Fine Granular, Direct-Compression Pharmaceutical Grade for tableting applications, and pre-blended Fine Granular systems with bulking agents for tabletable supplement manufacturing.
Bulk and reduced-MOQ shipments. Batch-level COA covering potency, particle size, flow characteristics, peroxide value, heavy metals, and microbiology.
Introduction
This SKU is the fine-granular particle-size format of Dry Vitamin D3 Powder, distinct from standard spray-dried powder by additional processing that produces uniform granules with improved flow and reduced segregation in dry-blend manufacturing.
Production starts with standard spray-dried Vitamin D3 powder, which is then granulated and classified to defined particle-size specifications optimized for pharmaceutical direct-compression tableting equipment.
Regulatory status follows that of standard Vitamin D3 (GRAS in the U.S., listed in major pharmacopoeias).
The fine-granular format addresses a specific manufacturing limitation of standard spray-dried powder: in high-speed pharmaceutical tableting, fine powders can segregate during hopper feed, producing tablets with inconsistent active-ingredient content. Granular formats reduce segregation and improve content uniformity.
Strategic positioning serves pharmaceutical and premium-supplement tableting where content uniformity matters for regulatory compliance and finished-product quality.
