Vitamin D3 (Cholecalciferol) Bulk Raw Material | Food & Pharma Grade Fat-Soluble Vitamin

Our bulk Vitamin D3 (Cholecalciferol) is premium fat-soluble micronutrient refined from lanolin-extracted 7-dehydrocholesterol via controlled photochemical synthesis. We manufacture three mainstream commercial grades: pure crystalline D3, high-concentration D3 oil, and cold-water dispersible CWD microencapsulated powder, fully compliant with USP, EP, ICH, FDA and global food safety norms.

Different from generic D3 raw materials in the market, our whole production line adopts amber light shielding, nitrogen-sealed spray drying and low-temperature crystallization technologies to minimize inactive isomer generation and oxidation loss, locking stable potency throughout shelf life. All batches are supported with full COA, TDS, MSDS and EDMF regulatory documents to simplify global import filing for food manufacturers, pharmaceutical factories and feed compounders. The CWD powder variant dissolves rapidly in cold water without agglomeration, compatible with tableting, beverage premix, hard capsule and feed pellet production workflows. Strict heavy metal, residual solvent and microbiology testing eliminate cross-contamination risks, holding Kosher, Halal, cGMP, ISO22000 and FSSC22000 certifications for cross-border wholesale supply.

Q1: What raw material source do you use for Vitamin D3 production?

A: Our Vitamin D3 is synthesized from lanolin-derived 7-dehydrocholesterol, no animal bone/liver extract added; full raw material traceability records available for every shipment.

Q2: How do you guarantee D3 potency stability during long ocean transit?

A: All goods adopt nitrogen-sealed light-blocking packaging and full reefer cold chain transport below 15°C; amber UV-shielded containers prevent photodegradation, avoiding potency drop in cross-season shipping.

Q3: Is your CWD Vitamin D3 powder suitable for high-pressure tableting production?

A: Yes. The carbohydrate microcapsule matrix is compression-resistant, protecting inner lipid D3 core under standard tableting mechanical shear without potency loss or demixing.

Q4: What certifications can you provide for EU & US customs clearance?

A: We supply cGMP, ISO22000, FSSC22000, Kosher, Halal certificates, USDMF, EDMF, batch COA, MSDS and residual solvent test reports complying with ICH Q3C.

Q5: What is the shelf life of your three D3 grades under proper storage?

A: Pure crystalline D3: 24 months; Vitamin D3 oil: 18 months; CWD cold-water dispersible powder: 20 months, stored sealed below 15°C away from sunlight.

Q6: Can you offer custom low-potency premix D3 for infant formula use?

A: Available. Our factory follows strict infant food-grade impurity limits, with extra low heavy metal and pre-Vitamin D3 content, fully matching infant nutrition additive standards.

Q7: How to solve D3 oil solidification risk during winter cross-border delivery?

A: We arrange temperature-controlled reefer containers maintained above crystallization threshold; insulated outer cartons prevent oil coagulation in low-temperature winter transit.

Q8: What is your order MOQ and delivery lead time for bulk export?

A: Trial order MOQ: 1kg; bulk wholesale MOQ: 25kg. Standard lead time 7–10 working days after deposit; rush order 3–5 days for urgent import demands.
