Buyer Decision Guide
Vitamin grades are specified by potency, carrier and purity, and the same vitamin name can cover several physical forms. Confirm the exact form and the analytical method before comparing quotations; overage and stability requirements are project-specific.
- Confirm the exact physical form and carrier
- Check declared potency and the assay method
- Review stability and overage needs for your format
- Confirm light, heat and oxygen sensitivity in handling
How This Grade Differs
Vitamin D3 Oil must be compared on physical form, carrier and declared potency rather than on the vitamin name alone. Powder, oil, crystal and diluted forms behave differently in blending, dosing and shelf life.
Compare these related grades before approval:
For a substitution review, confirm the vitamin D3 identity, 1.0 MIU/g potency and HPLC method, oil delivery form and the current offered-batch COA. D2 and D3, or powder, oil and crystal grades, require separate specification approval.
Application Areas
Discuss the intended formulation and processing conditions with the supplier before selecting this oil ingredient.
Packaging and Delivery

Quality and Documentation
Representative batch LXDF260602 supports the specification table above. Use the cited record for preliminary comparison and request the offered-lot COA for final technical approval. Batch COA, specification sheet, agreed third-party testing and export documents are available for buyer verification.
