Sourcing, Extraction and Manufacturing Process: Vitamin D3 (Cholecalciferol)Updated a month ago

Source and Origin 

• Sourcing: The Vitamin D3 (cholecalciferol) in Dr. Berg products is derived fromlanolin, which is extracted from the wool grease of sheep.
• Location: These sheep are raised in Australia and New Zealand.
• Rearing Practices: The sheep used for production are pasture-grazed. While conventional farming in these regions may involve some pesticide use on pastures or animals, the lanolin undergoes an extensive purification process.
• Safety Standards: The final Vitamin D3 extract complies with all international safety standards and is purified to remove contaminants.

Extraction and Manufacturing Process 

The conversion of sheep wool lanolin into a high-quality supplement involves a sophisticated, multi-step purification process: 

1. Purification: Lanolin is extracted from the wool and converted into purified Vitamin D3 crystals.
2. Dissolution: These crystals dissolve in caprylic/capric triglyceride oil (MCT oil).
3. Stabilization: The mixture is stabilized with d-alpha-tocopherol (Vitamin E) to prevent oxidation.
