Description
The 500,000 IU/g feed-grade format of Vitamin D3, the dominant commercial format for animal feed premix manufacturing. Provides Vitamin D3 in a stable, free-flowing powder optimized for feed-mill handling.
Pale yellow to brown free-flowing powder. Spray-dried gelatin or starch matrix protects Vitamin D3 from oxidation and enables uniform dispersion in feed-mill mixing.
We supply feed-grade Vitamin D3 from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production.
Common market grades include Vitamin D3 500 Feed Grade (this SKU), Vitamin D3 500 CWS Feed Grade (cold-water-soluble variant for liquid feed applications, catalog id 14620), and pre-blended Vitamin AD3 systems combining Vitamin A and D3 in defined ratios.
Bulk and reduced-MOQ shipments. Batch-level COA covering potency, particle size, peroxide value, heavy metals, and microbiology.
Introduction
This SKU is the 500,000 IU/g powder format of Vitamin D3 optimized for animal feed applications, distinct from human-food and pharmaceutical-grade Vitamin D3 (catalog id 7890) by application orientation and specification tolerances.
Production starts with Vitamin D3 resin (crude concentrate from UV irradiation of 7-dehydrocholesterol), which is standardized to defined IU concentration in oil, then mixed with food-grade gelatin or modified starch, spray-dried, and milled to defined particle-size specifications.
Regulatory status follows that of pharmaceutical-grade Vitamin D3 (GRAS in the U.S., E670 not applicable as Vitamin D3 is not regulated by E-number in EU), with feed-application specifications applying.
The 500 IU/g potency level matches premix manufacturing protocols across major poultry, swine, and dairy feed-mill operations. The spray-dried powder format provides 2 to 3 years of shelf stability when stored protected from light, heat, and humidity.
Strategic positioning serves the animal-feed and premix-manufacturing segment specifically. China dominates global production with substantial export volumes to animal nutrition markets worldwide.
