Q1 How to accurately convert 0.05% and 1.25% concentrations?

Both 1.25% and 0.05% are calculated based on the actual content of pure 25-hydroxyvitamin D₃ per kilogram of product .

Q2 How does the recommended dosage correspond to international units (IU) of vitamin D₃?

Conversion ratio:  

Example: 500,000 IU/g vitamin D₃

1. Convert IU to μg: 500,000 IU/g × 0.025 μg/IU = 12,500 μg/g = 12.5 mg/g

2. Calculate per kilogram of product:

Conclusion: Each kilogram of product contains 12.5 g vitamin D₃.

Q3 Is 25-hydroxyvitamin D₃ water-soluble?

Structurally, 25-hydroxyvitamin D₃ contains a hydrophilic hydroxyl group at the C-25 position of vitamin D₃.
