Ergocalciferol (Vitamin D2) Crystalline Powder | USP EP Standard Plant-Based Vitamin D Raw Material

Ergocalciferol, also known as Vitamin D2, is premium plant-sourced crystalline powder produced via controlled UV irradiation of fungal ergosterol raw materials. Our factory strictly follows USP & EP monographs to deliver consistent potency at 40,000 IU per milligram, ideal as fat-soluble vitamin API for pharmaceutical formulations, vegan dietary supplements and food fortification worldwide. Unlike generic D2 raw materials, we adopt cryogenic crystallization and nitrogen-blanketed micronization to cut toxic isomer impurities, guaranteeing stable potency during long-distance cold-chain export to EU, North America, Southeast Asia and Oceania markets. All batches support full batch traceability, complete regulatory documents and third-party testing reports for global importers, supplement brands and pharma manufacturers.

Q1: What's the difference between plant-based Ergocalciferol (D2) and Cholecalciferol (D3)?

A1: Ergocalciferol Vitamin D2 is extracted from fungal plant sterols, fully vegan and suitable for vegetarian/clean-label products; D3 mostly comes from lanolin animal sources. Our D2 raw material meets all global vegan supplement regulatory requirements, with stable potency matching USP/EP standards.

Q2: How do you prevent Ergocalciferol from converting back to tachysterol impurities during production & shipping?

A2: We adopt narrow-band UV filtering in photochemical reaction and sub-zero cooling crystallization to limit over-irradiation byproducts. All packaging uses nitrogen blanketing and light-blocking materials, plus cold-chain transit to avoid isomer reversion.

Q3: What export documents can you provide for customs clearance?

A3: Each batch supplies Certificate of Analysis (COA), Technical Data Sheet (TDS), Material Safety Data Sheet (MSDS), factory GMP audit report, origin certificate, heavy metal ICP-MS test report and microbial test report; we support customized documents for EU, US, Australia customs registration.

Q4: Can I order small trial samples before bulk bulk purchase?

A4: Yes, 1kg sample orders are available with full testing documents. After sample validation, we support flexible bulk order quantities from 25kg to multiple metric tons with stable factory supply capacity.

Q5: Is your Ergocalciferol free from genetically modified materials?

A5: Verified Non-GMO throughout the whole production chain, raw fungal sterols are non-transgenic, with official Non-GMO statement provided for every shipment.
