Our cholecalciferol powder complies with GB26687-2011 specifications with potency of ≥100,000 IU /g and a fine particle distribution (40-100 mesh) for excellent flowability during tablet compression and even dispersion in fortified drinks. We are ISO9001 certified and have 30 technical professionals on our team, providing dependable solutions for the dietary supplement, functional food and animal nutrition industries globally.

What Is Vitamin D3 Powder?

The substance is technically called cholecalciferol (CAS No.: 67-97-0). It is the bio-active form of vitamin D, which is required to control the metabolism of calcium and phosphorus. This fat soluble vitamin is a white to light yellow powder with the chemical formula C28H46O and a molecular weight of 398.66.

Cholecalciferol has better bioavailability than vitamin D2 (ergocalciferol). It is made in human skin spontaneously from 7-dehydrocholesterol when exposed to UV light. Micro-encapsulated formulations preserve the active chemical throughout heat processing and storage in industrial environments.

Our product corresponds to the reference standard GB26687-2011. The powder is very stable across a variety of pH values and retains its potency during cycles of pasteurization, which makes it suitable for demanding industrial applications.

Functions

The product performs five critical physiological functions:

Function	Description
Calcium & Phosphorus Absorption	Enhances intestinal uptake to achieve optimal plasma saturation levels
Bone Development Support	Promotes skeletal growth and mineralization processes in all life stages
Dental Health Maintenance	Strengthens tooth enamel through improved calcium deposition
Renal Regulation	Increases phosphorus reabsorption through renal tubules, preventing mineral loss
Metabolic Balance	Maintains normal blood citrate concentration and prevents amino acid excretion

These processes function in synergy. The vitamin also affects parathyroid hormone production, immunological function and cellular differentiation in addition to skeletal health.

Application Fields

We provide our cholecalciferol powder to three specific B2B sectors:

Dietary Supplement Manufacturing: The free-flowing qualities of the powder are useful for hard-shell capsules and multi-vitamin tablets. 40-100 mesh particle size avoids segregation in high speed mixing processes. The content uniformity is uniform in the manufacturing batches and fulfills the pharmacopeial standards for tablets crushed at 10-15 kN pressures.

Programs for Food Enrichment: Cold Water Soluble (CWS) grades dissolve quickly in dairy products, baby foods and morning cereals. Micro-encapsulation technology protects the Vitamin D3 Powder from heat shocks during extrusion and pasteurization. Fortified beverages are clear without oily ringing even in the acidic juice matrices (pH 3.5-4.2).

Animal Nutrition Premixes: Feed-grade formulations withstand pelleting processes involving steam conditioning at 80-85°C. Cross-linked coating technologies prevent activity loss during hydrothermal stress and interaction with trace minerals like copper and iron in complete feed formulations.

Quality Control

Our quality assurance system operates through five validation layers:

All raw ingredients are acquired only from verified providers. The identification of the individual batch is confirmed by UV spectrophotometry before entering manufacturing. In-process controls are used to monitor crucial control points such as particle size distribution, moisture (<5%) and microbiological parameters.

Finished products receive comprehensive testing including:

• Potency analysis via HPLC (High-Performance Liquid Chromatography)
• Heavy metal screening (Pb, As, Cd, Hg below regulatory limits)
• Microbiological enumeration (TPC, yeast, mold, pathogens)
• Stability studies under ICH Q1A conditions

Retention samples remain stored for traceability. Our laboratory holds CNAS accreditation, ensuring test results meet international recognition standards.

Certificates

• ISO9001 Quality Management System Certification (2012)
• SGS Verification
• HALAL-related Certifications
• High-tech Enterprise of Shaanxi Province (2013)
• Private Science and Technology Enterprise of Shaanxi Province
